+"""Convert graminit.[ch] spit out by pgen to Python code.
+
+Pgen is the Python parser generator.  It is useful to quickly create a
+parser from a grammar file in Python's grammar notation.  But I don't
+want my parsers to be written in C (yet), so I'm translating the
+parsing tables to Python data structures and writing a Python parse
+engine.
+
+Note that the token numbers are constants determined by the standard
+Python tokenizer.  The standard token module defines these numbers and
+their names (the names are not used much).  The token numbers are
+hardcoded into the Python tokenizer and into pgen.  A Python
+implementation of the Python tokenizer is also available, in the
+standard tokenize module.
+
+On the other hand, symbol numbers (representing the grammar's
+non-terminals) are assigned by pgen based on the actual grammar
+input.
+
+Note: this module is pretty much obsolete; the pgen module generates
+equivalent grammar tables directly from the Grammar.txt input file
+without having to invoke the Python pgen C program.

+class Grammar(object):
+    """Pgen parsing tables conversion class.
+
+    Once initialized, this class supplies the grammar tables for the
+    parsing engine implemented by parse.py.  The parsing engine
+    accesses the instance variables directly.  The class here does not
+    provide initialization of the tables; several subclasses exist to
+    do this (see the conv and pgen modules).
+
+    The load() method reads the tables from a pickle file, which is
+    much faster than the other ways offered by subclasses.  The pickle
+    file is written by calling dump() (after loading the grammar
+    tables using a subclass).  The report() method prints a readable
+    representation of the tables to stdout, for debugging.
+
+    The instance variables are as follows:
+
+    symbol2number -- a dict mapping symbol names to numbers.  Symbol
+                     numbers are always 256 or higher, to distinguish
+                     them from token numbers, which are between 0 and
+                     255 (inclusive).
+
+    number2symbol -- a dict mapping numbers to symbol names;
+                     these two are each other's inverse.
+
+    states        -- a list of DFAs, where each DFA is a list of
+                     states, each state is a list of arcs, and each
+                     arc is a (i, j) pair where i is a label and j is
+                     a state number.  The DFA number is the index into
+                     this list.  (This name is slightly confusing.)
+                     Final states are represented by a special arc of
+                     the form (0, j) where j is its own state number.
+
+    dfas          -- a dict mapping symbol numbers to (DFA, first)
+                     pairs, where DFA is an item from the states list
+                     above, and first is a set of tokens that can
+                     begin this grammar rule (represented by a dict
+                     whose values are always 1).
+
+    labels        -- a list of (x, y) pairs where x is either a token
+                     number or a symbol number, and y is either None
+                     or a string; the strings are keywords.  The label
+                     number is the index in this list; label numbers
+                     are used to mark state transitions (arcs) in the
+                     DFAs.
+
+    start         -- the number of the grammar's start symbol.

+"""Tokenization help for Python programs.
+
+generate_tokens(readline) is a generator that breaks a stream of
+text into Python tokens.  It accepts a readline-like method which is called
+repeatedly to get the next line of input (or "" for EOF).  It generates
+5-tuples with these members:
+
+    the token type (see token.py)
+    the token (a string)
+    the starting (row, column) indices of the token (a 2-tuple of ints)
+    the ending (row, column) indices of the token (a 2-tuple of ints)
+    the original line (string)
+
+It is designed to match the working of the Python tokenizer exactly, except
+that it produces COMMENT tokens for comments and gives type OP for all
+operators
+
+Older entry points
+    tokenize_loop(readline, tokeneater)
+    tokenize(readline, tokeneater=printtoken)
+are the same, except instead of generating tokens, tokeneater is a callback
+function to which the 5 fields described above are passed as 5 arguments,
+each time a new token is found."""

+    allows a formatting string to be specified. If none is supplied, the

+                        call was issued (if available)

+def basicConfig(**kwargs):
+    """
+    Do basic configuration for the logging system.
+
+    This function does nothing if the root logger already has handlers
+    configured, unless the keyword argument *force* is set to ``True``.
+    It is a convenience method intended for use by simple scripts
+    to do one-shot configuration of the logging package.
+
+    The default behaviour is to create a StreamHandler which writes to
+    sys.stderr, set a formatter using the BASIC_FORMAT format string, and
+    add the handler to the root logger.
+
+    A number of optional keyword arguments may be specified, which can alter
+    the default behaviour.
+
+    filename  Specifies that a FileHandler be created, using the specified
+              filename, rather than a StreamHandler.
+    filemode  Specifies the mode to open the file, if filename is specified
+              (if filemode is unspecified, it defaults to 'a').
+    format    Use the specified format string for the handler.
+    datefmt   Use the specified date/time format.
+    style     If a format string is specified, use this to specify the
+              type of format string (possible values '%', '{', '$', for
+              %-formatting, :meth:`str.format` and :class:`string.Template`
+              - defaults to '%').
+    level     Set the root logger level to the specified level.
+    stream    Use the specified stream to initialize the StreamHandler. Note
+              that this argument is incompatible with 'filename' - if both
+              are present, 'stream' is ignored.
+    handlers  If specified, this should be an iterable of already created
+              handlers, which will be added to the root handler. Any handler
+              in the list which does not have a formatter assigned will be
+              assigned the formatter created in this function.
+    force     If this keyword  is specified as true, any existing handlers
+              attached to the root logger are removed and closed, before
+              carrying out the configuration as specified by the other
+              arguments.
+    encoding  If specified together with a filename, this encoding is passed to
+              the created FileHandler, causing it to be used when the file is
+              opened.
+    errors    If specified together with a filename, this value is passed to the
+              created FileHandler, causing it to be used when the file is
+              opened in text mode. If not specified, the default value is
+              `backslashreplace`.
+
+    Note that you could specify a stream created using open(filename, mode)
+    rather than passing the filename and mode in. However, it should be
+    remembered that StreamHandler does not close its stream (since it may be
+    using sys.stdout or sys.stderr), whereas FileHandler closes its stream
+    when the handler is closed.

+# Server process to keep track of unlinked resources (like shared memory
+# segments, semaphores etc.) and clean them.
+#
+# On Unix we run a server process which keeps track of unlinked
+# resources. The server ignores SIGINT and SIGTERM and reads from a
+# pipe.  Every other process of the program has a copy of the writable
+# end of the pipe, so we get EOF when all other processes have exited.
+# Then the server process unlinks any remaining resource names.
+#
+# This is important because there may be system limits for such resources: for
+# instance, the system only supports a limited number of named semaphores, and
+# shared-memory segments live in the RAM. If a python process leaks such a
+# resource, this resource will not be removed till the next reboot.  Without
+# this resource tracker process, "killall python" would probably leave unlinked
+# resources.

+# MarkupSafe
+
+MarkupSafe implements a text object that escapes characters so it is
+safe to use in HTML and XML. Characters that have special meanings are
+replaced so that they display as the actual characters. This mitigates
+injection attacks, meaning untrusted user input can safely be displayed
+on a page.
+
+
+## Examples
+
+```pycon
+>>> from markupsafe import Markup, escape
+
+>>> # escape replaces special characters and wraps in Markup
+>>> escape("<script>alert(document.cookie);</script>")
+Markup('&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
+
+>>> # wrap in Markup to mark text "safe" and prevent escaping
+>>> Markup("<strong>Hello</strong>")
+Markup('<strong>hello</strong>')
+
+>>> escape(Markup("<strong>Hello</strong>"))
+Markup('<strong>hello</strong>')
+
+>>> # Markup is a str subclass
+>>> # methods and operators escape their arguments
+>>> template = Markup("Hello <em>{name}</em>")
+>>> template.format(name='"World"')
+Markup('Hello <em>&#34;World&#34;</em>')
+```

+
+BLP1 files, used mostly in Warcraft III, are not fully supported.
+All types of BLP2 files used in World of Warcraft are supported.
+
+The BLP file structure consists of a header, up to 16 mipmaps of the
+texture
+
+Texture sizes must be powers of two, though the two dimensions do
+not have to be equal; 512x256 is valid, but 512x200 is not.
+The first mipmap (mipmap #0) is the full size image; each subsequent
+mipmap halves both dimensions. The final mipmap should be 1x1.
+
+BLP files come in many different flavours:
+* JPEG-compressed (type == 0) - only supported for BLP1.
+* RAW images (type == 1, encoding == 1). Each mipmap is stored as an
+  array of 8-bit values, one per pixel, left to right, top to bottom.
+  Each value is an index to the palette.
+* DXT-compressed (type == 1, encoding == 2):
+- DXT1 compression is used if alpha_encoding == 0.
+  - An additional alpha bit is used if alpha_depth == 1.
+  - DXT3 compression is used if alpha_encoding == 1.
+  - DXT5 compression is used if alpha_encoding == 7.

+Independence War 2: Edge Of Chaos - Texture File Format - 16 October 2001
+
+The textures used for 3D objects in Independence War 2: Edge Of Chaos are in a
+packed custom format called FTEX. This file format uses file extensions FTC
+and FTU.
+* FTC files are compressed textures (using standard texture compression).
+* FTU files are not compressed.
+Texture File Format
+The FTC and FTU texture files both use the same format. This
+has the following structure:
+{header}
+{format_directory}
+{data}
+Where:
+{header} = {
+    u32:magic,
+    u32:version,
+    u32:width,
+    u32:height,
+    u32:mipmap_count,
+    u32:format_count
+}
+
+* The "magic" number is "FTEX".
+* "width" and "height" are the dimensions of the texture.
+* "mipmap_count" is the number of mipmaps in the texture.
+* "format_count" is the number of texture formats (different versions of the
+same texture) in this file.
+
+{format_directory} = format_count * { u32:format, u32:where }
+
+The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB
+uncompressed textures.
+The texture data for a format starts at the position "where" in the file.
+
+Each set of texture data in the file has the following structure:
+{data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } }
+* "mipmap_size" is the number of bytes in that mip level. For compressed
+textures this is the size of the texture data compressed with DXT1. For 24 bit
+uncompressed textures, this is 3 * width * height. Following this are the image
+bytes for that mipmap level.
+
+Note: All data is stored in little-Endian (Intel) byte order.

+        and ``dither`` and ``palette`` are ignored.
+
+        When converting from "PA", if an "RGBA" palette is present, the alpha
+        channel from the image will be used instead of the values from the palette.

+
+    The pyCMS.py module provides a "clean" interface between Python/PIL and
+    pyCMSdll, taking care of some of the more complex handling of the direct
+    pyCMSdll functions, as well as error-checking and making sure that all
+    relevant data is kept together.
+
+    While it is possible to call pyCMSdll functions directly, it's not highly
+    recommended.
+
+    Version History:
+
+        1.0.0 pil       Oct 2013 Port to LCMS 2.
+
+        0.1.0 pil mod   March 10, 2009
+
+                        Renamed display profile to proof profile. The proof
+                        profile is the profile of the device that is being
+                        simulated, not the profile of the device which is
+                        actually used to display/print the final simulation
+                        (that'd be the output profile) - also see LCMSAPI.txt
+                        input colorspace -> using 'renderingIntent' -> proof
+                        colorspace -> using 'proofRenderingIntent' -> output
+                        colorspace
+
+                        Added LCMS FLAGS support.
+                        Added FLAGS["SOFTPROOFING"] as default flag for
+                        buildProofTransform (otherwise the proof profile/intent
+                        would be ignored).
+
+        0.1.0 pil       March 2009 - added to PIL, as PIL.ImageCms
+
+        0.0.2 alpha     Jan 6, 2002
+
+                        Added try/except statements around type() checks of
+                        potential CObjects... Python won't let you use type()
+                        on them, and raises a TypeError (stupid, if you ask
+                        me!)
+
+                        Added buildProofTransformFromOpenProfiles() function.
+                        Additional fixes in DLL, see DLL code for details.
+
+        0.0.1 alpha     first public release, Dec. 26, 2002

+# drawing interface operations
+#
+# History:
+# 1996-04-13 fl   Created (experimental)
+# 1996-08-07 fl   Filled polygons, ellipses.
+# 1996-08-13 fl   Added text support
+# 1998-06-28 fl   Handle I and F images
+# 1998-12-29 fl   Added arc; use arc primitive to draw ellipses
+# 1999-01-10 fl   Added shape stuff (experimental)
+# 1999-02-06 fl   Added bitmap support
+# 1999-02-11 fl   Changed all primitives to take options
+# 1999-02-20 fl   Fixed backwards compatibility
+# 2000-10-12 fl   Copy on write, when necessary
+# 2001-02-18 fl   Use default ink for bitmap/text also in fill mode
+# 2002-10-24 fl   Added support for CSS-style color strings
+# 2002-12-10 fl   Added experimental support for RGBA-on-RGB drawing
+# 2002-12-11 fl   Refactored low-level drawing API (work in progress)
+# 2004-08-26 fl   Made Draw() a factory function, added getdraw() support
+# 2004-09-04 fl   Added width support to line primitive
+# 2004-09-10 fl   Added font mode handling
+# 2006-06-19 fl   Added font bearing support (getmask2)

+# 1999-02-06 fl   rewrote most font management stuff in C
+# 1999-03-17 fl   take pth files into account in load_path (from Richard Jones)
+# 2001-02-17 fl   added freetype support
+# 2001-05-09 fl   added TransposedFont wrapper class
+# 2002-03-04 fl   make sure we have a "L" or "1" font
+# 2002-12-04 fl   skip non-directory entries in the system path
+# 2003-04-29 fl   add embedded default font
+# 2003-09-27 fl   added support for truetype charmap encodings

+JPEG quality settings equivalent to the Photoshop settings.
+Can be used when saving JPEG files.
+
+The following presets are available by default:
+``web_low``, ``web_medium``, ``web_high``, ``web_very_high``, ``web_maximum``,
+``low``, ``medium``, ``high``, ``maximum``.
+More presets can be added to the :py:data:`presets` dict if needed.
+
+To apply the preset, specify::
+
+  quality="preset_name"
+
+To apply only the quantization table::
+
+  qtables="preset_name"
+
+To apply only the subsampling setting::
+
+  subsampling="preset_name"
+
+Example::
+
+  im.save("image_name.jpg", quality="web_high")
+
+Subsampling
+-----------
+
+Subsampling is the practice of encoding images by implementing less resolution
+for chroma information than for luma information.
+(ref.: https://en.wikipedia.org/wiki/Chroma_subsampling)
+
+Possible subsampling values are 0, 1 and 2 that correspond to 4:4:4, 4:2:2 and
+4:2:0.
+
+You can get the subsampling of a JPEG with the
+:func:`.JpegImagePlugin.get_sampling` function.
+
+In JPEG compressed data a JPEG marker is used instead of an EXIF tag.
+(ref.: https://exiv2.org/tags.html)
+
+
+Quantization tables
+-------------------
+
+They are values use by the DCT (Discrete cosine transform) to remove
+*unnecessary* information from the image (the lossy part of the compression).
+(ref.: https://en.wikipedia.org/wiki/Quantization_matrix#Quantization_matrices,
+https://en.wikipedia.org/wiki/JPEG#Quantization)
+
+You can get the quantization tables of a JPEG with::
+
+  im.quantization
+
+This will return a dict with a number of lists. You can pass this dict
+directly as the qtables argument when saving a JPEG.
+
+The quantization table format in presets is a list with sublists. These formats
+are interchangeable.

+# TIFF file handling
+#
+# TIFF is a flexible, if somewhat aged, image file format originally
+# defined by Aldus.  Although TIFF supports a wide variety of pixel
+# layouts and compression methods, the name doesn't really stand for
+# "thousands of incompatible file formats," it just feels that way.
+#
+# To read TIFF data from a stream, the stream must be seekable.  For
+# progressive decoding, make sure to use TIFF files where the tag
+# directory is placed first in the file.
+#
+# History:
+# 1995-09-01 fl   Created
+# 1996-05-04 fl   Handle JPEGTABLES tag
+# 1996-05-18 fl   Fixed COLORMAP support
+# 1997-01-05 fl   Fixed PREDICTOR support
+# 1997-08-27 fl   Added support for rational tags (from Perry Stoll)
+# 1998-01-10 fl   Fixed seek/tell (from Jan Blom)
+# 1998-07-15 fl   Use private names for internal variables
+# 1999-06-13 fl   Rewritten for PIL 1.0 (1.0)
+# 2000-10-11 fl   Additional fixes for Python 2.0 (1.1)

+
+## Easy to integrate
+
+🤗 Accelerate was created for PyTorch users who like to write the training loop of PyTorch models but are reluctant to write and maintain the boilerplate code needed to use multi-GPUs/TPU/fp16.
+
+🤗 Accelerate abstracts exactly and only the boilerplate code related to multi-GPUs/TPU/fp16 and leaves the rest of your code unchanged.
+
+Here is an example:
+
+```diff
+  import torch
+  import torch.nn.functional as F
+  from datasets import load_dataset
++ from accelerate import Accelerator
+
++ accelerator = Accelerator()
+- device = 'cpu'
++ device = accelerator.device
+
+  model = torch.nn.Transformer().to(device)
+  optimizer = torch.optim.Adam(model.parameters())
+
+  dataset = load_dataset('my_dataset')
+  data = torch.utils.data.DataLoader(dataset, shuffle=True)
+
++ model, optimizer, data = accelerator.prepare(model, optimizer, data)
+
+  model.train()
+  for epoch in range(10):
+      for source, targets in data:
+          source = source.to(device)
+          targets = targets.to(device)
+
+          optimizer.zero_grad()
+
+          output = model(source)
+          loss = F.cross_entropy(output, targets)
+
+-         loss.backward()
++         accelerator.backward(loss)
+
+          optimizer.step()
+```
+
+As you can see in this example, by adding 5-lines to any standard PyTorch training script you can now run on any kind of single or distributed node setting (single CPU, single GPU, multi-GPUs and TPUs) as well as with or without mixed precision (fp8, fp16, bf16).
+
+In particular, the same code can then be run without modification on your local machine for debugging or your training environment.
+
+🤗 Accelerate even handles the device placement for you (which requires a few more changes to your code, but is safer in general), so you can even simplify your training loop further:
+
+```diff
+  import torch
+  import torch.nn.functional as F
+  from datasets import load_dataset
++ from accelerate import Accelerator
+
+- device = 'cpu'
++ accelerator = Accelerator()
+
+- model = torch.nn.Transformer().to(device)
++ model = torch.nn.Transformer()
+  optimizer = torch.optim.Adam(model.parameters())
+
+  dataset = load_dataset('my_dataset')
+  data = torch.utils.data.DataLoader(dataset, shuffle=True)
+
++ model, optimizer, data = accelerator.prepare(model, optimizer, data)
+
+  model.train()
+  for epoch in range(10):
+      for source, targets in data:
+-         source = source.to(device)
+-         targets = targets.to(device)
+
+          optimizer.zero_grad()
+
+          output = model(source)
+          loss = F.cross_entropy(output, targets)
+
+-         loss.backward()
++         accelerator.backward(loss)
+
+          optimizer.step()
+```

+
+## Launching script
+
+🤗 Accelerate also provides an optional CLI tool that allows you to quickly configure and test your training environment before launching the scripts. No need to remember how to use `torch.distributed.run` or to write a specific launcher for TPU training!
+On your machine(s) just run:
+
+```bash
+accelerate config
+```
+
+and answer the questions asked. This will generate a config file that will be used automatically to properly set the default options when doing
+
+```bash
+accelerate launch my_script.py --args_to_my_script
+``` 
+
+For instance, here is how you would run the GLUE example on the MRPC task (from the root of the repo):
+
+```bash
+accelerate launch examples/nlp_example.py
+```
+
+This CLI tool is **optional**, and you can still use `python my_script.py` or `python -m torchrun my_script.py` at your convenience.
+
+You can also directly pass in the arguments you would to `torchrun` as arguments to `accelerate launch` if you wish to not run` accelerate config`.
+
+For example, here is how to launch on two GPUs:
+
+```bash
+accelerate launch --multi_gpu --num_processes 2 examples/nlp_example.py
+```
+
+To learn more, check the CLI documentation available [here](https://huggingface.co/docs/accelerate/package_reference/cli).
+
+Or view the configuration zoo [here](https://github.com/huggingface/accelerate/blob/main/examples/config_yaml_templates/)
+
+## Launching multi-CPU run using MPI
+
+🤗 Here is another way to launch multi-CPU run using MPI. You can learn how to install Open MPI on [this page](https://www.open-mpi.org/faq/?category=building#easy-build). You can use Intel MPI or MVAPICH as well.
+Once you have MPI setup on your cluster, just run:
+```bash
+accelerate config
+```
+Answer the questions that are asked, selecting to run using multi-CPU, and answer "yes" when asked if you want accelerate to launch mpirun.
+Then, use `accelerate launch` with your script like:
+```bash
+accelerate launch examples/nlp_example.py
+```
+Alternatively, you can use mpirun directly, without using the CLI like:
+```bash
+mpirun -np 2 python examples/nlp_example.py
+```
+
+## Launching training using DeepSpeed
+
+🤗 Accelerate supports training on single/multiple GPUs using DeepSpeed. To use it, you don't need to change anything in your training code; you can set everything using just `accelerate config`. However, if you desire to tweak your DeepSpeed related args from your Python script, we provide you the `DeepSpeedPlugin`.
+
+```python
+from accelerate import Accelerator, DeepSpeedPlugin
+
+# deepspeed needs to know your gradient accumulation steps beforehand, so don't forget to pass it
+# Remember you still need to do gradient accumulation by yourself, just like you would have done without deepspeed
+deepspeed_plugin = DeepSpeedPlugin(zero_stage=2, gradient_accumulation_steps=2)
+accelerator = Accelerator(mixed_precision='fp16', deepspeed_plugin=deepspeed_plugin)
+
+# How to save your 🤗 Transformer?
+accelerator.wait_for_everyone()
+unwrapped_model = accelerator.unwrap_model(model)
+unwrapped_model.save_pretrained(save_dir, save_function=accelerator.save, state_dict=accelerator.get_state_dict(model))
+```
+
+Note: DeepSpeed support is experimental for now. In case you get into some problem, please open an issue.
+
+## Launching your training from a notebook
+
+🤗 Accelerate also provides a `notebook_launcher` function you can use in a notebook to launch a distributed training. This is especially useful for Colab or Kaggle notebooks with a TPU backend. Just define your training loop in a `training_function` then in your last cell, add:
+
+```python
+from accelerate import notebook_launcher
+
+notebook_launcher(training_function)
+```
+
+An example can be found in [this notebook](https://github.com/huggingface/notebooks/blob/main/examples/accelerate_examples/simple_nlp_example.ipynb). [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/huggingface/notebooks/blob/main/examples/accelerate_examples/simple_nlp_example.ipynb)
+
+## Why should I use 🤗 Accelerate?
+
+You should use 🤗 Accelerate when you want to easily run your training scripts in a distributed environment without having to renounce full control over your training loop. This is not a high-level framework above PyTorch, just a thin wrapper so you don't have to learn a new library. In fact, the whole API of 🤗 Accelerate is in one class, the `Accelerator` object.
+
+## Why shouldn't I use 🤗 Accelerate?
+
+You shouldn't use 🤗 Accelerate if you don't want to write a training loop yourself. There are plenty of high-level libraries above PyTorch that will offer you that, 🤗 Accelerate is not one of them.
+
+## Frameworks using 🤗 Accelerate
+
+If you like the simplicity of 🤗 Accelerate but would prefer a higher-level abstraction around its capabilities, some frameworks and libraries that are built on top of 🤗 Accelerate are listed below:
+
+* [Amphion](https://github.com/open-mmlab/Amphion) is a toolkit for Audio, Music, and Speech Generation. Its purpose is to support reproducible research and help junior researchers and engineers get started in the field of audio, music, and speech generation research and development.
+* [Animus](https://github.com/Scitator/animus) is a minimalistic framework to run machine learning experiments. Animus highlights common "breakpoints" in ML experiments and provides a unified interface for them within [IExperiment](https://github.com/Scitator/animus/blob/main/animus/core.py#L76).
+* [Catalyst](https://github.com/catalyst-team/catalyst#getting-started) is a PyTorch framework for Deep Learning Research and Development.

Catalyst provides a [Runner](https://catalyst-team.github.io/catalyst/api/core.html#runner) to connect all parts of the experiment: hardware backend, data transformations, model training, and inference logic.
+* [fastai](https://github.com/fastai/fastai#installing) is a PyTorch framework for Deep Learning that simplifies training fast and accurate neural nets using modern best practices. fastai provides a [Learner](https://docs.fast.ai/learner.html#Learner) to handle the training, fine-tuning, and inference of deep learning algorithms.
+* [Finetuner](https://github.com/jina-ai/finetuner) is a service that enables models to create higher-quality embeddings for semantic search, visual similarity search, cross-modal text<->image search, recommendation systems, clustering, duplication detection, anomaly detection, or other uses.
+* [InvokeAI](https://github.com/invoke-ai/InvokeAI) is a creative engine for Stable Diffusion models, offering industry-leading WebUI, terminal usage support, and serves as the foundation for many commercial products.
+* [Kornia](https://kornia.readthedocs.io/en/latest/get-started/introduction.html) is a differentiable library that allows classical computer vision to be integrated into deep learning models. Kornia provides a [Trainer](https://kornia.readthedocs.io/en/latest/x.html#kornia.x.Trainer) with the specific purpose to train and fine-tune the supported deep learning algorithms within the library.
+* [Open Assistant](https://projects.laion.ai/Open-Assistant/) is a chat-based assistant that understands tasks, can interact with their party systems, and retrieve information dynamically to do so. 
+* [pytorch-accelerated](https://github.com/Chris-hughes10/pytorch-accelerated) is a lightweight training library, with a streamlined feature set centered around a general-purpose [Trainer](https://pytorch-accelerated.readthedocs.io/en/latest/trainer.html), that places a huge emphasis on simplicity and transparency; enabling users to understand exactly what is going on under the hood, but without having to write and maintain the boilerplate themselves!
+* [Stable Diffusion web UI](https://github.com/AUTOMATIC1111/stable-diffusion-webui) is an open-source browser-based easy-to-use interface based on the Gradio library for Stable Diffusion.
+* [torchkeras](https://github.com/lyhue1991/torchkeras) is a simple tool for training pytorch model just in a keras style, a dynamic and beautiful plot is provided in notebook to monitor your loss or metric.
+* [transformers](https://github.com/huggingface/transformers) as a tool for helping train state-of-the-art machine learning models in PyTorch, Tensorflow, and JAX. (Accelerate is the backend for the PyTorch side).

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+class Accelerator:
+    """
+    Creates an instance of an accelerator for distributed training or mixed precision training.
+
+    Args:
+        device_placement (`bool`, *optional*, defaults to `True`):
+            Whether or not the accelerator should put objects on device (tensors yielded by the dataloader, model,
+            etc...).
+        mixed_precision (`str`, *optional*):
+            Whether or not to use mixed precision training. Choose from 'no','fp16','bf16' or 'fp8'. Will default to
+            the value in the environment variable `ACCELERATE_MIXED_PRECISION`, which will use the default value in the
+            accelerate config of the current system or the flag passed with the `accelerate.launch` command. 'fp8'
+            requires the installation of transformers-engine.
+        gradient_accumulation_steps (`int`, *optional*, default to 1):
+            The number of steps that should pass before gradients are accumulated. A number > 1 should be combined with
+            `Accelerator.accumulate`. If not passed, will default to the value in the environment variable
+            `ACCELERATE_GRADIENT_ACCUMULATION_STEPS`. Can also be configured through a `GradientAccumulationPlugin`.
+        cpu (`bool`, *optional*):
+            Whether or not to force the script to execute on CPU. Will ignore GPU available if set to `True` and force
+            the execution on one process only.
+        dataloader_config (`DataLoaderConfiguration`, *optional*):
+            A configuration for how the dataloaders should be handled in distributed scenarios.
+        deepspeed_plugin ([`~utils.DeepSpeedPlugin`] or dict of `str`: [`~utils.DeepSpeedPlugin`], *optional*):
+            Tweak your DeepSpeed related args using this argument. This argument is optional and can be configured
+            directly using *accelerate config*. If using multiple plugins, use the configured `key` property of each
+            plugin to access them from `accelerator.state.get_deepspeed_plugin(key)`. Alias for `deepspeed_plugins`.
+        fsdp_plugin ([`~utils.FullyShardedDataParallelPlugin`], *optional*):
+            Tweak your FSDP related args using this argument. This argument is optional and can be configured directly
+            using *accelerate config*
+        torch_tp_plugin ([`~utils.TorchTensorParallelPlugin`], *optional*):
+            Deprecated: use `parallelism_config` with `tp_size` instead.
+        megatron_lm_plugin ([`~utils.MegatronLMPlugin`], *optional*):
+            Tweak your MegatronLM related args using this argument. This argument is optional and can be configured
+            directly using *accelerate config*
+        rng_types (list of `str` or [`~utils.RNGType`]):
+            The list of random number generators to synchronize at the beginning of each iteration in your prepared
+            dataloaders. Should be one or several of:
+
+            - `"torch"`: the base torch random number generator
+            - `"cuda"`: the CUDA random number generator (GPU only)
+            - `"xla"`: the XLA random number generator (TPU only)
+            - `"generator"`: the `torch.Generator` of the sampler (or batch sampler if there is no sampler in your
+              dataloader) or of the iterable dataset (if it exists) if the underlying dataset is of that type.
+
+            Will default to `["torch"]` for PyTorch versions <=1.5.1 and `["generator"]` for PyTorch versions >= 1.6.
+        log_with (list of `str`, [`~utils.LoggerType`] or [`~tracking.GeneralTracker`], *optional*):
+            A list of loggers to be setup for experiment tracking. Should be one or several of:
+
+            - `"all"`
+            - `"tensorboard"`
+            - `"wandb"`
+            - `"trackio"`
+            - `"aim"`
+            - `"comet_ml"`
+            - `"mlflow"`
+            - `"dvclive"`
+            - `"swanlab"`
+            If `"all"` is selected, will pick up all available trackers in the environment and initialize them. Can
+            also accept implementations of `GeneralTracker` for custom trackers, and can be combined with `"all"`.
+        project_config ([`~utils.ProjectConfiguration`], *optional*):
+            A configuration for how saving the state can be handled.
+        project_dir (`str`, `os.PathLike`, *optional*):
+            A path to a directory for storing data such as logs of locally-compatible loggers and potentially saved
+            checkpoints.
+        step_scheduler_with_optimizer (`bool`, *optional*, defaults to `True`):
+            Set `True` if the learning rate scheduler is stepped at the same time as the optimizer, `False` if only
+            done under certain circumstances (at the end of each epoch, for instance).
+        kwargs_handlers (list of [`~utils.KwargsHandler`], *optional*)
+            A list of [`~utils.KwargsHandler`] to customize how the objects related to distributed training, profiling
+            or mixed precision are created. See [kwargs](kwargs) for more information.
+        dynamo_backend (`str` or [`~utils.DynamoBackend`], *optional*, defaults to `"no"`):
+            Set to one of the possible dynamo backends to optimize your training with torch dynamo.
+        dynamo_plugin ([`~utils.TorchDynamoPlugin`], *optional*):
+            A configuration for how torch dynamo should be handled, if more tweaking than just the `backend` or `mode`
+            is needed.
+        gradient_accumulation_plugin ([`~utils.GradientAccumulationPlugin`], *optional*):
+            A configuration for how gradient accumulation should be handled, if more tweaking than just the

+

+        checkpoint (`str` or `os.PathLike`):
+            The folder checkpoint to load. It can be:
+            - a path to a file containing a whole model state dict
+            - a path to a `.json` file containing the index to a sharded checkpoint
+            - a path to a folder containing a unique `.index.json` file and the shards of a checkpoint.
+        device_map (`Dict[str, Union[int, str, torch.device]]`, *optional*):
+            A map that specifies where each submodule should go. It doesn't need to be refined to each parameter/buffer
+            name, once a given module name is inside, every submodule of it will be sent to the same device.
+
+            To have Accelerate compute the most optimized `device_map` automatically, set `device_map="auto"`. For more
+            information about each option see [here](../concept_guides/big_model_inference#designing-a-device-map).
+            Defaults to None, which means [`dispatch_model`] will not be called.
+        max_memory (`Dict`, *optional*):
+            A dictionary device identifier to maximum memory. Will default to the maximum memory available for each GPU
+            and the available CPU RAM if unset.
+        no_split_module_classes (`List[str]`, *optional*):
+            A list of layer class names that should never be split across device (for instance any layer that has a
+            residual connection).
+        offload_folder (`str` or `os.PathLike`, *optional*):
+            If the `device_map` contains any value `"disk"`, the folder where we will offload weights.
+        offload_buffers (`bool`, *optional*, defaults to `False`):
+            In the layers that are offloaded on the CPU or the hard drive, whether or not to offload the buffers as
+            well as the parameters.
+        dtype (`str` or `torch.dtype`, *optional*):
+            If provided, the weights will be converted to that type when loaded.
+        offload_state_dict (`bool`, *optional*):
+            If `True`, will temporarily offload the CPU state dict on the hard drive to avoid getting out of CPU RAM if
+            the weight of the CPU state dict + the biggest shard does not fit. Will default to `True` if the device map
+            picked contains `"disk"` values.
+        skip_keys (`str` or `List[str]`, *optional*):
+            A list of keys to ignore when moving inputs or outputs between devices.
+        preload_module_classes (`List[str]`, *optional*):
+            A list of classes whose instances should load all their weights (even in the submodules) at the beginning
+            of the forward. This should only be used for classes that have submodules which are registered but not
+            called directly during the forward, for instance if a `dense` linear layer is registered, but at forward,
+            `dense.weight` and `dense.bias` are used in some operations instead of calling `dense` directly.
+        force_hooks (`bool`, *optional*, defaults to `False`):
+            Whether or not to force device hooks to be attached to the model even if all layers are dispatched to a
+            single device.
+        strict (`bool`, *optional*, defaults to `False`):
+            Whether to strictly enforce that the keys in the checkpoint state_dict match the keys of the model's
+            state_dict.
+        full_state_dict (`bool`, *optional*, defaults to `True`): if this is set to `True`, all the tensors in the
+            loaded state_dict will be gathered. No ShardedTensor and DTensor will be in the loaded state_dict.
+        broadcast_from_rank0 (`False`, *optional*, defaults to `False`): when the option is `True`, a distributed
+            `ProcessGroup` must be initialized. rank0 should receive a full state_dict and will broadcast the tensors
+            in the state_dict one by one to other ranks. Other ranks will receive the tensors and shard (if applicable)
+            according to the local shards in the model.

+            are split and broadcast to each process. Will default to `True` when the underlying dataset is an
+            `IterableDataset`, `False` otherwise.
+        even_batches (`bool`, *optional*, defaults to `True`):
+            If set to `True`, in cases where the total batch size across all processes does not exactly divide the
+            dataset, samples at the start of the dataset will be duplicated so the batch can be divided equally among
+            all workers.

+            If passed, this function will be used to slice tensors across `num_processes`. Will default to

+        data_seed (`int`, *optional*, defaults to `None`):
+            The seed to use for the underlying generator when using `use_seedable_sampler`. If `None`, the generator
+            will use the current default seed from torch.
+        non_blocking (`bool`, *optional*, defaults to `False`):
+            If set to `True`, dataloader will utilize non-blocking host-to-device transfers. If the dataloader has
+            `pin_memory` set to `True`, this will help to increase overlap between data transfer and computations.
+        use_stateful_dataloader (`bool`, *optional*, defaults to `False`):
+            "If set to true, the dataloader prepared by the Accelerator will be backed by "
+            "[torchdata.StatefulDataLoader](https://github.com/pytorch/data/tree/main/torchdata/stateful_dataloader).

+A. HISTORY OF THE SOFTWARE
+==========================
+
+Python was created in the early 1990s by Guido van Rossum at Stichting
+Mathematisch Centrum (CWI, see https://www.cwi.nl) in the Netherlands
+as a successor of a language called ABC.  Guido remains Python's
+principal author, although it includes many contributions from others.
+
+In 1995, Guido continued his work on Python at the Corporation for
+National Research Initiatives (CNRI, see https://www.cnri.reston.va.us)
+in Reston, Virginia where he released several versions of the
+software.
+
+In May 2000, Guido and the Python core development team moved to
+BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
+year, the PythonLabs team moved to Digital Creations, which became
+Zope Corporation.  In 2001, the Python Software Foundation (PSF, see
+https://www.python.org/psf/) was formed, a non-profit organization
+created specifically to own Python-related Intellectual Property.
+Zope Corporation was a sponsoring member of the PSF.
+
+All Python releases are Open Source (see https://opensource.org for
+the Open Source Definition).  Historically, most, but not all, Python
+releases have also been GPL-compatible; the table below summarizes
+the various releases.
+
+    Release         Derived     Year        Owner       GPL-
+                    from                                compatible? (1)
+
+    0.9.0 thru 1.2              1991-1995   CWI         yes
+    1.3 thru 1.5.2  1.2         1995-1999   CNRI        yes

+    2.2 and above   2.1.1       2001-now    PSF         yes
+
+Footnotes:
+
+(1) GPL-compatible doesn't mean that we're distributing Python under
+    the GPL.  All Python licenses, unlike the GPL, let you distribute
+    a modified version without making your changes open source.  The
+    GPL-compatible licenses make it possible to combine Python with
+    other software that is released under the GPL; the others don't.
+
+(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
+    because its license has a choice of law clause.  According to
+    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
+    is "not incompatible" with the GPL.
+
+Thanks to the many outside volunteers who have worked under Guido's
+direction to make these releases possible.

+([RFC 8305](https://www.rfc-editor.org/rfc/rfc8305.html))
+
+## Use case
+
+This library exists to allow connecting with
+[Happy Eyeballs](https://en.wikipedia.org/wiki/Happy_Eyeballs)
+([RFC 8305](https://www.rfc-editor.org/rfc/rfc8305.html))
+when you
+already have a list of addrinfo and not a DNS name.
+
+The stdlib version of `loop.create_connection()`
+will only work when you pass in an unresolved name which
+is not a good fit when using DNS caching or resolving
+names via another method such as `zeroconf`.
+
+## Installation
+
+Install this via pip (or your favourite package manager):
+
+`pip install aiohappyeyeballs`
+
+## License
+
+[aiohappyeyeballs is licensed under the same terms as cpython itself.](https://github.com/python/cpython/blob/main/LICENSE)
+
+## Example usage
+
+```python
+
+addr_infos = await loop.getaddrinfo("example.org", 80)
+
+socket = await start_connection(addr_infos)
+socket = await start_connection(addr_infos, local_addr_infos=local_addr_infos, happy_eyeballs_delay=0.2)
+
+transport, protocol = await loop.create_connection(
+    MyProtocol, sock=socket, ...)
+
+# Remove the first address for each family from addr_info
+pop_addr_infos_interleave(addr_info, 1)
+
+# Remove all matching address from addr_info
+remove_addr_infos(addr_info, "dead::beef::")
+
+# Convert a local_addr to local_addr_infos
+local_addr_infos = addr_to_addr_infos(("127.0.0.1",0))

+    Run coroutines with staggered start times and take the first to finish.
+
+    This method takes an iterable of coroutine functions. The first one is
+    started immediately. From then on, whenever the immediately preceding one
+    fails (raises an exception), or when *delay* seconds has passed, the next
+    coroutine is started. This continues until one of the coroutines complete
+    successfully, in which case all others are cancelled, or until all
+    coroutines fail.
+
+    The coroutines provided should be well-behaved in the following way:
+
+    * They should only ``return`` if completed successfully.
+
+    * They should always raise an exception if they did not complete
+      successfully. In particular, if they handle cancellation, they should

+            ``None``, the coroutines will run sequentially.

+          coroutine may return None on success, *winner_index* can be used
+          to definitively determine whether any coroutine won.
+
+        - *exceptions*: list of exceptions returned by the coroutines.
+          ``len(exceptions)`` is equal to the number of coroutines actually
+          started, and the order is the same as in ``coro_fns``. The winning

+
+Key Features
+============
+
+- Supports both client and server side of HTTP protocol.
+- Supports both client and server Web-Sockets out-of-the-box and avoids
+  Callback Hell.
+- Provides Web-server with middleware and pluggable routing.
+
+
+Getting started
+===============
+
+Client
+------
+
+To get something from the web:
+
+.. code-block:: python
+
+  import aiohttp
+  import asyncio
+
+  async def main():
+
+      async with aiohttp.ClientSession() as session:
+          async with session.get('http://python.org') as response:
+
+              print("Status:", response.status)
+              print("Content-type:", response.headers['content-type'])
+
+              html = await response.text()
+              print("Body:", html[:15], "...")
+
+  asyncio.run(main())
+
+This prints:
+
+.. code-block::
+
+    Status: 200
+    Content-type: text/html; charset=utf-8
+    Body: <!doctype html> ...
+
+Coming from `requests <https://requests.readthedocs.io/>`_ ? Read `why we need so many lines <https://aiohttp.readthedocs.io/en/latest/http_request_lifecycle.html>`_.
+
+Server
+------
+
+An example using a simple server:
+
+.. code-block:: python
+
+    # examples/server_simple.py
+    from aiohttp import web
+
+    async def handle(request):
+        name = request.match_info.get('name', "Anonymous")
+        text = "Hello, " + name
+        return web.Response(text=text)
+
+    async def wshandle(request):
+        ws = web.WebSocketResponse()
+        await ws.prepare(request)
+
+        async for msg in ws:
+            if msg.type == web.WSMsgType.text:
+                await ws.send_str("Hello, {}".format(msg.data))
+            elif msg.type == web.WSMsgType.binary:
+                await ws.send_bytes(msg.data)
+            elif msg.type == web.WSMsgType.close:
+                break
+
+        return ws
+
+
+    app = web.Application()
+    app.add_routes([web.get('/', handle),
+                    web.get('/echo', wshandle),
+                    web.get('/{name}', handle)])
+
+    if __name__ == '__main__':
+        web.run_app(app)

+This middleware implements HTTP Digest Authentication according to RFC 7616,
+providing a more secure alternative to Basic Authentication. It supports all
+standard hash algorithms including MD5, SHA, SHA-256, SHA-512 and their session
+variants, as well as both 'auth' and 'auth-int' quality of protection (qop) options.

+
+        This method safely updates the request body by first closing any existing
+        payload to prevent resource leaks, then setting the new body.
+
+        IMPORTANT: Always use this method instead of setting request.body directly.
+        Direct assignment to request.body will leak resources if the previous body
+        contains file handles, streams, or other resources that need cleanup.
+
+        Args:
+            body: The new body content. Can be:
+                - bytes/bytearray: Raw binary data
+                - str: Text data (will be encoded using charset from Content-Type)
+                - FormData: Form data that will be encoded as multipart/form-data
+                - Payload: A pre-configured payload object
+                - AsyncIterable: An async iterable of bytes chunks
+                - File-like object: Will be read and sent as binary data
+                - None: Clears the body
+
+        Usage:
+            # CORRECT: Use update_body
+            await request.update_body(b"new request data")
+
+            # WRONG: Don't set body directly
+            # request.body = b"new request data"  # This will leak resources!

+            await request.update_body(None)
+
+        Note:
+            This method is async because it may need to close file handles or
+            other resources associated with the previous payload. Always await
+            this method to ensure proper cleanup.
+
+        Warning:
+            Setting request.body directly is highly discouraged and can lead to:
+            - Resource leaks (unclosed file handles, streams)
+            - Memory leaks (unreleased buffers)
+            - Unexpected behavior with streaming payloads
+
+            It is not recommended to change the payload type in middleware. If the
+            body was already set (e.g., as bytes), it's best to keep the same type
+            rather than converting it (e.g., to str) as this may result in unexpected
+            behavior.

+
+Introduction
+============
+
+A project to manage callbacks in `asyncio` projects.
+
+``Signal`` is a list of registered asynchronous callbacks.
+
+The signal's life-cycle has two stages: after creation its content
+could be filled by using standard list operations: ``sig.append()``
+etc.
+
+After you call ``sig.freeze()`` the signal is *frozen*: adding, removing
+and dropping callbacks is forbidden.
+
+The only available operation is calling the previously registered
+callbacks by using ``await sig.send(data)``.
+
+For concrete usage examples see the `Signals
+<https://docs.aiohttp.org/en/stable/web_advanced.html#aiohttp-web-signals>
+section of the `Web Server Advanced
+<https://docs.aiohttp.org/en/stable/web_advanced.html>` chapter of the `aiohttp
+documentation`_.
+
+
+Installation

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,

+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+</a>
+
+## Installation
+
+```bash
+pip install annotated-doc
+```
+
+Or with `uv`:
+
+```Python
+uv add annotated-doc
+```
+
+## Usage
+
+Import `Doc` and pass a single literal string with the documentation for the specific parameter, class attribute, return type, or variable.
+
+For example, to document a parameter `name` in a function `hi` you could do:
+
+```Python
+from typing import Annotated
+
+from annotated_doc import Doc
+
+def hi(name: Annotated[str, Doc("Who to say hi to")]) -> None:
+    print(f"Hi, {name}!")
+```
+
+You can also use it to document class attributes:
+
+```Python
+from typing import Annotated
+
+from annotated_doc import Doc
+
+class User:
+    name: Annotated[str, Doc("The user's name")]
+    age: Annotated[int, Doc("The user's age")]
+```
+
+The same way, you could document return types and variables, or anything that could have a type annotation with `Annotated`.
+
+## Who Uses This
+
+`annotated-doc` was made for:
+
+* [FastAPI](https://fastapi.tiangolo.com/)
+* [Typer](https://typer.tiangolo.com/)
+* [SQLModel](https://sqlmodel.tiangolo.com/)
+* [Asyncer](https://asyncer.tiangolo.com/)
+
+`annotated-doc` is supported by [griffe-typingdoc](https://github.com/mkdocstrings/griffe-typingdoc), which powers reference documentation like the one in the [FastAPI Reference](https://fastapi.tiangolo.com/reference/).
+
+## Reasons not to use `annotated-doc`
+
+You are already comfortable with one of the existing docstring formats, like:
+
+* Sphinx
+* numpydoc
+* Google
+* Keras
+
+Your team is already comfortable using them.
+
+You prefer having the documentation about parameters all together in a docstring, separated from the code defining them.
+
+You care about a specific set of users, using one specific editor, and that editor already has support for the specific docstring format you use.
+
+## Reasons to use `annotated-doc`
+
+* No micro-syntax to learn for newcomers, it’s **just Python** syntax.
+* **Editing** would be already fully supported by default by any editor (current or future) supporting Python syntax, including syntax errors, syntax highlighting, etc.
+* **Rendering** would be relatively straightforward to implement by static tools (tools that don't need runtime execution), as the information can be extracted from the AST they normally already create.
+* **Deduplication of information**: the name of a parameter would be defined in a single place, not duplicated inside of a docstring.
+* **Elimination** of the possibility of having **inconsistencies** when removing a parameter or class variable and **forgetting to remove** its documentation.
+* **Minimization** of the probability of adding a new parameter or class variable and **forgetting to add its documentation**.
+* **Elimination** of the possibility of having **inconsistencies** between the **name** of a parameter in the **signature** and the name in the docstring when it is renamed.
+* **Access** to the documentation string for each symbol at **runtime**, including existing (older) Python versions.
+* A more formalized way to document other symbols, like type aliases, that could use Annotated.
+* **Support** for apps using FastAPI, Typer and others.
+* **AI Accessibility**: AI tools will have an easier way understanding each parameter as the distance from documentation to parameter is much closer.
+
+## History
+
+I ([@tiangolo](https://github.com/tiangolo)) originally wanted for this to be part of the Python standard library (in [PEP 727](https://peps.python.org/pep-0727/)), but the proposal was withdrawn as there was a fair amount of negative feedback and opposition.
+
+The conclusion was that this was better done as an external effort, in a third-party library.
+
+So, here it is, with a simpler approach, as a third-party library, in a way that can be used by others, starting with FastAPI and friends.

+
+[PEP-593](https://peps.python.org/pep-0593/) added `typing.Annotated` as a way of
+adding context-specific metadata to existing types, and specifies that
+`Annotated[T, x]` _should_ be treated as `T` by any tool or library without special
+logic for `x`.
+
+This package provides metadata objects which can be used to represent common
+constraints such as upper and lower bounds on scalar values and collection sizes,
+a `Predicate` marker for runtime checks, and
+descriptions of how we intend these metadata to be interpreted. In some cases,
+we also note alternative representations which do not require this package.
+
+## Install
+
+```bash
+pip install annotated-types
+```
+
+## Examples
+
+```python
+from typing import Annotated
+from annotated_types import Gt, Len, Predicate
+
+class MyClass:
+    age: Annotated[int, Gt(18)]                         # Valid: 19, 20, ...
+                                                        # Invalid: 17, 18, "19", 19.0, ...
+    factors: list[Annotated[int, Predicate(is_prime)]]  # Valid: 2, 3, 5, 7, 11, ...
+                                                        # Invalid: 4, 8, -2, 5.0, "prime", ...
+
+    my_list: Annotated[list[int], Len(0, 10)]           # Valid: [], [10, 20, 30, 40, 50]
+                                                        # Invalid: (1, 2), ["abc"], [0] * 20
+```
+
+## Documentation
+
+_While `annotated-types` avoids runtime checks for performance, users should not
+construct invalid combinations such as `MultipleOf("non-numeric")` or `Annotated[int, Len(3)]`.
+Downstream implementors may choose to raise an error, emit a warning, silently ignore
+a metadata item, etc., if the metadata objects described below are used with an
+incompatible type - or for any other reason!_
+
+### Gt, Ge, Lt, Le
+
+Express inclusive and/or exclusive bounds on orderable values - which may be numbers,
+dates, times, strings, sets, etc. Note that the boundary value need not be of the
+same type that was annotated, so long as they can be compared: `Annotated[int, Gt(1.5)]`
+is fine, for example, and implies that the value is an integer x such that `x > 1.5`.
+
+We suggest that implementors may also interpret `functools.partial(operator.le, 1.5)`
+as being equivalent to `Gt(1.5)`, for users who wish to avoid a runtime dependency on
+the `annotated-types` package.
+
+To be explicit, these types have the following meanings:
+
+* `Gt(x)` - value must be "Greater Than" `x` - equivalent to exclusive minimum
+* `Ge(x)` - value must be "Greater than or Equal" to `x` - equivalent to inclusive minimum
+* `Lt(x)` - value must be "Less Than" `x` - equivalent to exclusive maximum
+* `Le(x)` - value must be "Less than or Equal" to `x` - equivalent to inclusive maximum
+
+### Interval
+
+`Interval(gt, ge, lt, le)` allows you to specify an upper and lower bound with a single
+metadata object. `None` attributes should be ignored, and non-`None` attributes
+treated as per the single bounds above.
+
+### MultipleOf
+
+`MultipleOf(multiple_of=x)` might be interpreted in two ways:
+
+1. Python semantics, implying `value % multiple_of == 0`, or
+2. [JSONschema semantics](https://json-schema.org/draft/2020-12/json-schema-validation.html#rfc.section.6.2.1),
+   where `int(value / multiple_of) == value / multiple_of`.
+
+We encourage users to be aware of these two common interpretations and their
+distinct behaviours, especially since very large or non-integer numbers make
+it easy to cause silent data corruption due to floating-point imprecision.
+
+We encourage libraries to carefully document which interpretation they implement.
+
+### MinLen, MaxLen, Len
+
+`Len()` implies that `min_length <= len(value) <= max_length` - lower and upper bounds are inclusive.
+
+As well as `Len()` which can optionally include upper and lower bounds, we also
+provide `MinLen(x)` and `MaxLen(y)` which are equivalent to `Len(min_length=x)`
+and `Len(max_length=y)` respectively.
+
+`Len`, `MinLen`, and `MaxLen` may be used with any type which supports `len(value)`.
+
+Examples of usage:
+
+* `Annotated[list, MaxLen(10)]` (or `Annotated[list, Len(max_length=10))`) - list must have a length of 10 or less
+* `Annotated[str, MaxLen(10)]` - string must have a length of 10 or less
+* `Annotated[list, MinLen(3))` (or `Annotated[list, Len(min_length=3))`) - list must have a length of 3 or more
+* `Annotated[list, Len(4, 6)]` - list must have a length of 4, 5, or 6
+* `Annotated[list, Len(8, 8)]` - list must have a length of exactly 8
+
+#### Changed in v0.4.0
+
+* `min_inclusive` has been renamed to `min_length`, no change in meaning
+* `max_exclusive` has been renamed to `max_length`, upper bound is now **inclusive** instead of **exclusive**
+* The recommendation that slices are interpreted as `Len` has been removed due to ambiguity and different semantic
+  meaning of the upper bound in slices vs. `Len`
+
+See [issue #23](https://github.com/annotated-types/annotated-types/issues/23) for discussion.
+
+### Timezone
+
+`Timezone` can be used with a `datetime` or a `time` to express which timezones
+are allowed. `Annotated[datetime, Timezone(None)]` must be a naive datetime.
+`Timezone[...]` ([literal ellipsis](https://docs.python.org/3/library/constants.html#Ellipsis))
+expresses that any timezone-aware datetime is allowed. You may also pass a specific
+timezone string or [`tzinfo`](https://docs.python.org/3/library/datetime.html#tzinfo-objects)
+object such as `Timezone(timezone.utc)` or `Timezone("Africa/Abidjan")` to express that you only
+allow a specific timezone, though we note that this is often a symptom of fragile design.
+
+#### Changed in v0.x.x
+
+* `Timezone` accepts [`tzinfo`](https://docs.python.org/3/library/datetime.html#tzinfo-objects) objects instead of
+  `timezone`, extending compatibility to [`zoneinfo`](https://docs.python.org/3/library/zoneinfo.html) and third party libraries.
+
+### Unit
+
+`Unit(unit: str)` expresses that the annotated numeric value is the magnitude of
+a quantity with the specified unit. For example, `Annotated[float, Unit("m/s")]`
+would be a float representing a velocity in meters per second.
+
+Please note that `annotated_types` itself makes no attempt to parse or validate
+the unit string in any way. That is left entirely to downstream libraries,
+such as [`pint`](https://pint.readthedocs.io) or
+[`astropy.units`](https://docs.astropy.org/en/stable/units/).
+
+An example of how a library might use this metadata:
+
+```python
+from annotated_types import Unit
+from typing import Annotated, TypeVar, Callable, Any, get_origin, get_args
+
+# given a type annotated with a unit:
+Meters = Annotated[float, Unit("m")]
+
+
+# you can cast the annotation to a specific unit type with any
+# callable that accepts a string and returns the desired type
+T = TypeVar("T")
+def cast_unit(tp: Any, unit_cls: Callable[[str], T]) -> T | None:
+    if get_origin(tp) is Annotated:
+        for arg in get_args(tp):
+            if isinstance(arg, Unit):
+                return unit_cls(arg.unit)
+    return None
+
+
+# using `pint`
+import pint
+pint_unit = cast_unit(Meters, pint.Unit)
+
+
+# using `astropy.units`
+import astropy.units as u
+astropy_unit = cast_unit(Meters, u.Unit)
+```
+
+### Predicate
+
+`Predicate(func: Callable)` expresses that `func(value)` is truthy for valid values.
+Users should prefer the statically inspectable metadata above, but if you need
+the full power and flexibility of arbitrary runtime predicates... here it is.
+
+For some common constraints, we provide generic types:
+
+* `IsLower       = Annotated[T, Predicate(str.islower)]`
+* `IsUpper       = Annotated[T, Predicate(str.isupper)]`
+* `IsDigit       = Annotated[T, Predicate(str.isdigit)]`
+* `IsFinite      = Annotated[T, Predicate(math.isfinite)]`
+* `IsNotFinite   = Annotated[T, Predicate(Not(math.isfinite))]`
+* `IsNan         = Annotated[T, Predicate(math.isnan)]`
+* `IsNotNan      = Annotated[T, Predicate(Not(math.isnan))]`
+* `IsInfinite    = Annotated[T, Predicate(math.isinf)]`
+* `IsNotInfinite = Annotated[T, Predicate(Not(math.isinf))]`
+
+so that you can write e.g. `x: IsFinite[float] = 2.0` instead of the longer
+(but exactly equivalent) `x: Annotated[float, Predicate(math.isfinite)] = 2.0`.
+
+Some libraries might have special logic to handle known or understandable predicates,
+for example by checking for `str.isdigit` and using its presence to both call custom
+logic to enforce digit-only strings, and customise some generated external schema.
+Users are therefore encouraged to avoid indirection like `lambda s: s.lower()`, in
+favor of introspectable methods such as `str.lower` or `re.compile("pattern").search`.
+
+To enable basic negation of commonly used predicates like `math.isnan` without introducing introspection that makes it impossible for implementers to introspect the predicate we provide a `Not` wrapper that simply negates the predicate in an introspectable manner. Several of the predicates listed above are created in this manner.
+
+We do not specify what behaviour should be expected for predicates that raise
+an exception.  For example `Annotated[int, Predicate(str.isdigit)]` might silently
+skip invalid constraints, or statically raise an error; or it might try calling it
+and then propagate or discard the resulting
+`TypeError: descriptor 'isdigit' for 'str' objects doesn't apply to a 'int' object`
+exception.  We encourage libraries to document the behaviour they choose.
+
+### Doc
+
+`doc()` can be used to add documentation information in `Annotated`, for function and method parameters, variables, class attributes, return types, and any place where `Annotated` can be used.
+
+It expects a value that can be statically analyzed, as the main use case is for static analysis, editors, documentation generators, and similar tools.
+
+It returns a `DocInfo` class with a single attribute `documentation` containing the value passed to `doc()`.
+
+This is the early adopter's alternative form of the [`typing-doc` proposal](https://github.com/tiangolo/fastapi/blob/typing-doc/typing_doc.md).
+
+### Integrating downstream types with `GroupedMetadata`
+
+Implementers may choose to provide a convenience wrapper that groups multiple pieces of metadata.
+This can help reduce verbosity and cognitive overhead for users.
+For example, an implementer like Pydantic might provide a `Field` or `Meta` type that accepts keyword arguments and transforms these into low-level metadata:
+
+```python
+from dataclasses import dataclass
+from typing import Iterator
+from annotated_types import GroupedMetadata, Ge
+
+@dataclass
+class Field(GroupedMetadata):
+    ge: int | None = None
+    description: str | None = None
+
+    def __iter__(self) -> Iterator[object]:
+        # Iterating over a GroupedMetadata object should yield annotated-types
+        # constraint metadata objects which describe it as fully as possible,
+        # and may include other unknown objects too.
+        if self.ge is not None:
+            yield Ge(self.ge)
+        if self.description is not None:
+            yield Description(self.description)
+```
+
+Libraries consuming annotated-types constraints should check for `GroupedMetadata` and unpack it by iterating over the object and treating the results as if they had been "unpacked" in the `Annotated` type.  The same logic should be applied to the [PEP 646 `Unpack` type](https://peps.python.org/pep-0646/), so that `Annotated[T, Field(...)]`, `Annotated[T, Unpack[Field(...)]]` and `Annotated[T, *Field(...)]` are all treated consistently.
+
+Libraries consuming annotated-types should also ignore any metadata they do not recongize that came from unpacking a `GroupedMetadata`, just like they ignore unrecognized metadata in `Annotated` itself.
+
+Our own `annotated_types.Interval` class is a `GroupedMetadata` which unpacks itself into `Gt`, `Lt`, etc., so this is not an abstract concern.  Similarly, `annotated_types.Len` is a `GroupedMetadata` which unpacks itself into `MinLen` (optionally) and `MaxLen`.
+
+### Consuming metadata
+
+We intend to not be prescriptive as to _how_ the metadata and constraints are used, but as an example of how one might parse constraints from types annotations see our [implementation in `test_main.py`](https://github.com/annotated-types/annotated-types/blob/f59cf6d1b5255a0fe359b93896759a180bec30ae/tests/test_main.py#L94-L103).
+
+It is up to the implementer to determine how this metadata is used.
+You could use the metadata for runtime type checking, for generating schemas or to generate example data, amongst other use cases.
+
+## Design & History
+
+This package was designed at the PyCon 2022 sprints by the maintainers of Pydantic
+and Hypothesis, with the goal of making it as easy as possible for end-users to
+provide more informative annotations for use by runtime libraries.
+
+It is deliberately minimal, and following PEP-593 allows considerable downstream
+discretion in what (if anything!) they choose to support. Nonetheless, we expect
+that staying simple and covering _only_ the most common use-cases will give users
+and maintainers the best experience we can. If you'd like more constraints for your
+types - follow our lead, by defining them and documenting them downstream!

+
+    We provide a few predefined predicates for common string constraints:

+
+    Some libraries might have special logic to handle certain predicates, e.g. by
+    checking for `str.isdigit` and using its presence to both call custom logic to
+    enforce digit-only strings, and customise some generated external schema.
+
+    We do not specify what behaviour should be expected for predicates that raise
+    an exception.  For example `Annotated[int, Predicate(str.isdigit)]` might silently

+# The embodiment of the adaptive LL(*), ALL(*), parsing strategy.
+#
+# <p>
+# The basic complexity of the adaptive strategy makes it harder to understand.
+# We begin with ATN simulation to build paths in a DFA. Subsequent prediction
+# requests go through the DFA first. If they reach a state without an edge for
+# the current symbol, the algorithm fails over to the ATN simulation to
+# complete the DFA path for the current input (until it finds a conflict state
+# or uniquely predicting state).</p>
+#
+# <p>
+# All of that is done without using the outer context because we want to create
+# a DFA that is not dependent upon the rule invocation stack when we do a
+# prediction. One DFA works in all contexts. We avoid using context not
+# necessarily because it's slower, although it can be, but because of the DFA
+# caching problem. The closure routine only considers the rule invocation stack
+# created during prediction beginning in the decision rule. For example, if
+# prediction occurs without invoking another rule's ATN, there are no context
+# stacks in the configurations. When lack of context leads to a conflict, we
+# don't know if it's an ambiguity or a weakness in the strong LL(*) parsing
+# strategy (versus full LL(*)).</p>
+#
+# <p>
+# When SLL yields a configuration set with conflict, we rewind the input and
+# retry the ATN simulation, this time using full outer context without adding
+# to the DFA. Configuration context stacks will be the full invocation stacks
+# from the start rule. If we get a conflict using full context, then we can
+# definitively say we have a true ambiguity for that input sequence. If we
+# don't get a conflict, it implies that the decision is sensitive to the outer
+# context. (It is not context-sensitive in the sense of context-sensitive
+# grammars.)</p>
+#
+# <p>
+# The next time we reach this DFA state with an SLL conflict, through DFA
+# simulation, we will again retry the ATN simulation using full context mode.
+# This is slow because we can't save the results and have to "interpret" the
+# ATN each time we get that input.</p>
+#
+# <p>
+# <strong>CACHING FULL CONTEXT PREDICTIONS</strong></p>
+#
+# <p>
+# We could cache results from full context to predicted alternative easily and
+# that saves a lot of time but doesn't work in presence of predicates. The set
+# of visible predicates from the ATN start state changes depending on the
+# context, because closure can fall off the end of a rule. I tried to cache
+# tuples (stack context, semantic context, predicted alt) but it was slower
+# than interpreting and much more complicated. Also required a huge amount of
+# memory. The goal is not to create the world's fastest parser anyway. I'd like
+# to keep this algorithm simple. By launching multiple threads, we can improve
+# the speed of parsing across a large number of files.</p>
+#
+# <p>
+# There is no strict ordering between the amount of input used by SLL vs LL,
+# which makes it really hard to build a cache for full context. Let's say that
+# we have input A B C that leads to an SLL conflict with full context X. That
+# implies that using X we might only use A B but we could also use A B C D to
+# resolve conflict. Input A B C D could predict alternative 1 in one position
+# in the input and A B C E could predict alternative 2 in another position in
+# input. The conflicting SLL configurations could still be non-unique in the
+# full context prediction, which would lead us to requiring more input than the
+# original A B C.	To make a	prediction cache work, we have to track	the exact
+# input	used during the previous prediction. That amounts to a cache that maps
+# X to a specific DFA for that context.</p>
+#
+# <p>
+# Something should be done for left-recursive expression predictions. They are
+# likely LL(1) + pred eval. Easier to do the whole SLL unless error and retry
+# with full LL thing Sam does.</p>
+#
+# <p>
+# <strong>AVOIDING FULL CONTEXT PREDICTION</strong></p>
+#
+# <p>
+# We avoid doing full context retry when the outer context is empty, we did not
+# dip into the outer context by falling off the end of the decision state rule,
+# or when we force SLL mode.</p>
+#
+# <p>
+# As an example of the not dip into outer context case, consider as super
+# constructor calls versus function calls. One grammar might look like
+# this:</p>
+#
+# <pre>
+# ctorBody
+#   : '{' superCall? stat* '}'
+#   ;
+# </pre>
+#
+# <p>
+# Or, you might see something like</p>
+#
+# <pre>
+# stat
+#   : superCall ';'
+#   | expression ';'
+#   | ...
+#   ;
+# </pre>
+#
+# <p>
+# In both cases I believe that no closure operations will dip into the outer
+# context. In the first case ctorBody in the worst case will stop at the '}'.
+# In the 2nd case it should stop at the ';'. Both cases should stay within the
+# entry rule and not dip into the outer context.</p>
+#
+# <p>
+# <strong>PREDICATES</strong></p>
+#
+# <p>
+# Predicates are always evaluated if present in either SLL or LL both. SLL and
+# LL simulation deals with predicates differently. SLL collects predicates as
+# it performs closure operations like ANTLR v3 did. It delays predicate
+# evaluation until it reaches and accept state. This allows us to cache the SLL
+# ATN simulation whereas, if we had evaluated predicates on-the-fly during
+# closure, the DFA state configuration sets would be different and we couldn't
+# build up a suitable DFA.</p>
+#
+# <p>
+# When building a DFA accept state during ATN simulation, we evaluate any
+# predicates and return the sole semantically valid alternative. If there is
+# more than 1 alternative, we report an ambiguity. If there are 0 alternatives,
+# we throw an exception. Alternatives without predicates act like they have
+# true predicates. The simple way to think about it is to strip away all
+# alternatives with false predicates and choose the minimum alternative that
+# remains.</p>
+#
+# <p>
+# When we start in the DFA and reach an accept state that's predicated, we test
+# those and return the minimum semantically viable alternative. If no
+# alternatives are viable, we throw an exception.</p>
+#
+# <p>
+# During full LL ATN simulation, closure always evaluates predicates and
+# on-the-fly. This is crucial to reducing the configuration set size during
+# closure. It hits a landmine when parsing with the Java grammar, for example,
+# without this on-the-fly evaluation.</p>
+#
+# <p>
+# <strong>SHARING DFA</strong></p>
+#
+# <p>
+# All instances of the same parser share the same decision DFAs through a
+# static field. Each instance gets its own ATN simulator but they share the
+# same {@link #decisionToDFA} field. They also share a
+# {@link PredictionContextCache} object that makes sure that all
+# {@link PredictionContext} objects are shared among the DFA states. This makes
+# a big size difference.</p>
+#
+# <p>
+# <strong>THREAD SAFETY</strong></p>
+#
+# <p>
+# The {@link ParserATNSimulator} locks on the {@link #decisionToDFA} field when
+# it adds a new DFA object to that array. {@link #addDFAEdge}
+# locks on the DFA for the current decision when setting the
+# {@link DFAState#edges} field. {@link #addDFAState} locks on
+# the DFA for the current decision when looking up a DFA state to see if it
+# already exists. We must make sure that all requests to add DFA states that
+# are equivalent result in the same shared DFA object. This is because lots of
+# threads will be trying to update the DFA at once. The
+# {@link #addDFAState} method also locks inside the DFA lock
+# but this time on the shared context cache when it rebuilds the
+# configurations' {@link PredictionContext} objects using cached
+# subgraphs/nodes. No other locking occurs, even during DFA simulation. This is
+# safe as long as we can guarantee that all threads referencing
+# {@code s.edge[t]} get the same physical target {@link DFAState}, or
+# {@code null}. Once into the DFA, the DFA simulation does not reference the
+# {@link DFA#states} map. It follows the {@link DFAState#edges} field to new
+# targets. The DFA simulator will either find {@link DFAState#edges} to be
+# {@code null}, to be non-{@code null} and {@code dfa.edges[t]} null, or
+# {@code dfa.edges[t]} to be non-null. The
+# {@link #addDFAEdge} method could be racing to set the field
+# but in either case the DFA simulator works; if {@code null}, and requests ATN
+# simulation. It could also race trying to get {@code dfa.edges[t]}, but either
+# way it will work because it's not doing a test and set operation.</p>
+#
+# <p>
+# <strong>Starting with SLL then failing to combined SLL/LL (Two-Stage
+# Parsing)</strong></p>
+#
+# <p>
+# Sam pointed out that if SLL does not give a syntax error, then there is no
+# point in doing full LL, which is slower. We only have to try LL if we get a
+# syntax error. For maximum speed, Sam starts the parser set to pure SLL
+# mode with the {@link BailErrorStrategy}:</p>
+#
+# <pre>
+# parser.{@link Parser#getInterpreter() getInterpreter()}.{@link #setPredictionMode setPredictionMode}{@code (}{@link PredictionMode#SLL}{@code )};
+# parser.{@link Parser#setErrorHandler setErrorHandler}(new {@link BailErrorStrategy}());
+# </pre>
+#
+# <p>
+# If it does not get a syntax error, then we're done. If it does get a syntax
+# error, we need to retry with the combined SLL/LL strategy.</p>
+#
+# <p>
+# The reason this works is as follows. If there are no SLL conflicts, then the
+# grammar is SLL (at least for that input set). If there is an SLL conflict,
+# the full LL analysis must yield a set of viable alternatives which is a
+# subset of the alternatives reported by SLL. If the LL set is a singleton,
+# then the grammar is LL but not SLL. If the LL set is the same size as the SLL
+# set, the decision is SLL. If the LL set has size &gt; 1, then that decision
+# is truly ambiguous on the current input. If the LL set is smaller, then the
+# SLL conflict resolution might choose an alternative that the full LL would
+# rule out as a possibility based upon better context information. If that's

+# alternatives.</p>
+#
+# <p>
+# Let's say we have a set of SLL conflicting alternatives {@code {1, 2, 3}} and
+# a smaller LL set called <em>s</em>. If <em>s</em> is {@code {2, 3}}, then SLL
+# parsing will get an error because SLL will pursue alternative 1. If
+# <em>s</em> is {@code {1, 2}} or {@code {1, 3}} then both SLL and LL will
+# choose the same alternative because alternative one is the minimum of either
+# set. If <em>s</em> is {@code {2}} or {@code {3}} then SLL will get a syntax
+# error. If <em>s</em> is {@code {1}} then SLL will succeed.</p>
+#
+# <p>
+# Of course, if the input is invalid, then we will get an error for sure in
+# both SLL and LL parsing. Erroneous input will therefore require 2 passes over

+    # Implements first-edge (loop entry) elimination as an optimization
+    #  during closure operations.  See antlr/antlr4#1398.
+    #
+    # The optimization is to avoid adding the loop entry config when
+    # the exit path can only lead back to the same
+    # StarLoopEntryState after popping context at the rule end state
+    # (traversing only epsilon edges, so we're still in closure, in
+    # this same rule).
+    #
+    # We need to detect any state that can reach loop entry on
+    # epsilon w/o exiting rule. We don't have to look at FOLLOW
+    # links, just ensure that all stack tops for config refer to key
+    # states in LR rule.
+    #
+    # To verify we are in the right situation we must first check
+    # closure is at a StarLoopEntryState generated during LR removal.
+    # Then we check that each stack top of context is a return state
+    # from one of these cases:
+    #
+    #   1. 'not' expr, '(' type ')' expr. The return state points at loop entry state
+    #   2. expr op expr. The return state is the block end of internal block of (...)*
+    #   3. 'between' expr 'and' expr. The return state of 2nd expr reference.
+    #      That state points at block end of internal block of (...)*.
+    #   4. expr '?' expr ':' expr. The return state points at block end,
+    #      which points at loop entry state.
+    #
+    # If any is true for each stack top, then closure does not add a
+    # config to the current config set for edge[0], the loop entry branch.
+    #
+    #  Conditions fail if any context for the current config is:
+    #
+    #   a. empty (we'd fall out of expr to do a global FOLLOW which could
+    #      even be to some weird spot in expr) or,
+    #   b. lies outside of expr or,
+    #   c. lies within expr but at a state not the BlockEndState
+    #   generated during LR removal
+    #
+    # Do we need to evaluate predicates ever in closure for this case?
+    #
+    # No. Predicates, including precedence predicates, are only
+    # evaluated when computing a DFA start state. I.e., only before
+    # the lookahead (but not parser) consumes a token.
+    #
+    # There are no epsilon edges allowed in LR rule alt blocks or in
+    # the "primary" part (ID here). If closure is in
+    # StarLoopEntryState any lookahead operation will have consumed a
+    # token as there are no epsilon-paths that lead to
+    # StarLoopEntryState. We do not have to evaluate predicates
+    # therefore if we are in the generated StarLoopEntryState of a LR
+    # rule. Note that when making a prediction starting at that
+    # decision point, decision d=2, compute-start-state performs
+    # closure starting at edges[0], edges[1] emanating from
+    # StarLoopEntryState. That means it is not performing closure on
+    # StarLoopEntryState during compute-start-state.
+    #
+    # How do we know this always gives same prediction answer?
+    #
+    # Without predicates, loop entry and exit paths are ambiguous
+    # upon remaining input +b (in, say, a+b). Either paths lead to
+    # valid parses. Closure can lead to consuming + immediately or by
+    # falling out of this call to expr back into expr and loop back
+    # again to StarLoopEntryState to match +b. In this special case,
+    # we choose the more efficient path, which is to take the bypass
+    # path.
+    #
+    # The lookahead language has not changed because closure chooses
+    # one path over the other. Both paths lead to consuming the same
+    # remaining input during a lookahead operation. If the next token
+    # is an operator, lookahead will enter the choice block with
+    # operators. If it is not, lookahead will exit expr. Same as if
+    # closure had chosen to enter the choice block immediately.
+    #
+    # Closure is examining one config (some loopentrystate, some alt,
+    # context) which means it is considering exactly one alt. Closure
+    # always copies the same alt to any derived configs.
+    #
+    # How do we know this optimization doesn't mess up precedence in

+    #
+    # Looking through expr from left edge of stat only has to confirm
+    # that an input, say, a+b+c; begins with any valid interpretation
+    # of an expression. The precedence actually doesn't matter when

+     #
+     # s : (ID | ID ID?) ';' ;
+     #
+     # When the ATN simulation reaches the state before ';', it has a DFA
+     # state that looks like: [12|1|[], 6|2|[], 12|2|[]]. Naturally
+     # 12|1|[] and 12|2|[] conflict, but we cannot stop processing this node
+     # because alternative to has another way to continue, via [6|2|[]].
+     # The key is that we have a single state that has config's only associated
+     # with a single alternative, 2, and crucially the state transitions
+     # among the configurations are all non-epsilon transitions. That means
+     # we don't consider any conflicts that include alternative 2. So, we

+     # conflicting alts when there is an intersection with an alternative
+     # associated with a single alt state in the state&rarr;config-list map.

+     # also a 3rd nonconflicting configuration for a different alternative:
+     # [1|1|[], 1|2|[], 8|3|[]]. This can come about from grammar:

+     # conflict and no amount of further lookahead will separate the two.
+     # However, alternative 3 will be able to continue and so we do not
+     # stop working on this state. In the previous example, we're concerned
+     # with states associated with the conflicting alternatives. Here alt
+     # 3 is not associated with the conflicting configs, but since we can continue
+     # looking for input reasonably, I don't declare the state done. We

+    # cannot lead to a unique SLL prediction.</p>
+    #
+    # <p>Assuming combined SLL+LL parsing, an SLL configuration set with only
+    # conflicting subsets should fall back to full LL, even if the

+    # {@code {1,2}} and {@code {3,4}}. If there is at least one non-conflicting
+    # configuration, SLL could continue with the hopes that more lookahead will
+    # resolve via one of those non-conflicting configurations.</p>
+    #
+    # <p>Here's the prediction termination rule them: SLL (for SLL+LL parsing)

+    # <p>As a heuristic, we stop prediction when we see any conflicting subset
+    # unless we see a state that only has one alternative associated with it.
+    # The single-alt-state thing lets prediction continue upon rules like
+    # (otherwise, it would admit defeat too soon):</p>
+    #
+    # <p>{@code [12|1|[], 6|2|[], 12|2|[]]. s : (ID | ID ID?) ';' ;}</p>
+    #
+    # <p>When the ATN simulation reaches the state before {@code ';'}, it has a
+    # DFA state that looks like: {@code [12|1|[], 6|2|[], 12|2|[]]}. Naturally
+    # {@code 12|1|[]} and {@code 12|2|[]} conflict, but we cannot stop
+    # processing this node because alternative to has another way to continue,
+    # via {@code [6|2|[]]}.</p>
+    #
+    # <p>It also let's us continue for this rule:</p>
+    #
+    # <p>{@code [1|1|[], 1|2|[], 8|3|[]] a : A | A | A B ;}</p>
+    #
+    # <p>After matching input A, we reach the stop state for rule A, state 1.
+    # State 8 is the state right before B. Clearly alternatives 1 and 2
+    # conflict and no amount of further lookahead will separate the two.
+    # However, alternative 3 will be able to continue and so we do not stop
+    # working on this state. In the previous example, we're concerned with
+    # states associated with the conflicting alternatives. Here alt 3 is not
+    # associated with the conflicting configs, but since we can continue
+    # looking for input reasonably, don't declare the state done.</p>
+    #
+    # <p><strong>PURE SLL PARSING</strong></p>
+    #
+    # <p>To handle pure SLL parsing, all we have to do is make sure that we
+    # combine stack contexts for configurations that differ only by semantic
+    # predicate. From there, we can do the usual SLL termination heuristic.</p>
+    #
+    # <p><strong>PREDICATES IN SLL+LL PARSING</strong></p>
+    #
+    # <p>SLL decisions don't evaluate predicates until after they reach DFA stop
+    # states because they need to create the DFA cache that works in all
+    # semantic situations. In contrast, full LL evaluates predicates collected
+    # during start state computation so it can ignore predicates thereafter.
+    # This means that SLL termination detection can totally ignore semantic
+    # predicates.</p>
+    #
+    # <p>Implementation-wise, {@link ATNConfigSet} combines stack contexts but not
+    # semantic predicate contexts so we might see two configurations like the
+    # following.</p>
+    #
+    # <p>{@code (s, 1, x, {}), (s, 1, x', {p})}</p>
+    #
+    # <p>Before testing these configurations against others, we have to merge
+    # {@code x} and {@code x'} (without modifying the existing configurations).
+    # For example, we test {@code (x+x')==x''} when looking for conflicts in
+    # the following configurations.</p>
+    #
+    # <p>{@code (s, 1, x, {}), (s, 1, x', {p}), (s, 2, x'', {})}</p>
+    #
+    # <p>If the configuration set has predicates (as indicated by
+    # {@link ATNConfigSet#hasSemanticContext}), this algorithm makes a copy of
+    # the configurations to strip out all of the predicates so that a standard
+    # {@link ATNConfigSet} will merge everything ignoring predicates.</p>

+    # <p>Can we stop looking ahead during ATN simulation or is there some
+    # uncertainty as to which alternative we will ultimately pick, after
+    # consuming more input? Even if there are partial conflicts, we might know
+    # that everything is going to resolve to the same minimum alternative. That
+    # means we can stop since no more lookahead will change that fact. On the
+    # other hand, there might be multiple conflicts that resolve to different
+    # minimums. That means we need more look ahead to decide which of those
+    # alternatives we should predict.</p>
+    #
+    # <p>The basic idea is to split the set of configurations {@code C}, into
+    # conflicting subsets {@code (s, _, ctx, _)} and singleton subsets with
+    # non-conflicting configurations. Two configurations conflict if they have
+    # identical {@link ATNConfig#state} and {@link ATNConfig#context} values
+    # but different {@link ATNConfig#alt} value, e.g. {@code (s, i, ctx, _)}
+    # and {@code (s, j, ctx, _)} for {@code i!=j}.</p>
+    #
+    # <p>Reduce these configuration subsets to the set of possible alternatives.
+    # You can compute the alternative subsets in one pass as follows:</p>
+    #
+    # <p>{@code A_s,ctx = {i | (s, i, ctx, _)}} for each configuration in
+    # {@code C} holding {@code s} and {@code ctx} fixed.</p>
+    #
+    # <p>Or in pseudo-code, for each configuration {@code c} in {@code C}:</p>
+    #
+    # <pre>
+    # map[c] U= c.{@link ATNConfig#alt alt} # map hash/equals uses s and x, not
+    # alt and not pred
+    # </pre>
+    #
+    # <p>The values in {@code map} are the set of {@code A_s,ctx} sets.</p>
+    #
+    # <p>If {@code |A_s,ctx|=1} then there is no conflict associated with
+    # {@code s} and {@code ctx}.</p>
+    #
+    # <p>Reduce the subsets to singletons by choosing a minimum of each subset. If
+    # the union of these alternative subsets is a singleton, then no amount of
+    # more lookahead will help us. We will always pick that alternative. If,
+    # however, there is more than one alternative, then we are uncertain which
+    # alternative to predict and must continue looking for resolution. We may
+    # or may not discover an ambiguity in the future, even if there are no
+    # conflicting subsets this round.</p>
+    #
+    # <p>The biggest sin is to terminate early because it means we've made a
+    # decision but were uncertain as to the eventual outcome. We haven't used
+    # enough lookahead. On the other hand, announcing a conflict too late is no
+    # big deal; you will still have the conflict. It's just inefficient. It
+    # might even look until the end of file.</p>
+    #
+    # <p>No special consideration for semantic predicates is required because
+    # predicates are evaluated on-the-fly for full LL prediction, ensuring that
+    # no configuration contains a semantic context during the termination
+    # check.</p>
+    #
+    # <p><strong>CONFLICTING CONFIGS</strong></p>
+    #
+    # <p>Two configurations {@code (s, i, x)} and {@code (s, j, x')}, conflict
+    # when {@code i!=j} but {@code x=x'}. Because we merge all
+    # {@code (s, i, _)} configurations together, that means that there are at
+    # most {@code n} configurations associated with state {@code s} for
+    # {@code n} possible alternatives in the decision. The merged stacks
+    # complicate the comparison of configuration contexts {@code x} and
+    # {@code x'}. Sam checks to see if one is a subset of the other by calling
+    # merge and checking to see if the merged result is either {@code x} or
+    # {@code x'}. If the {@code x} associated with lowest alternative {@code i}
+    # is the superset, then {@code i} is the only possible prediction since the
+    # others resolve to {@code min(i)} as well. However, if {@code x} is
+    # associated with {@code j>i} then at least one stack configuration for
+    # {@code j} is not in conflict with alternative {@code i}. The algorithm
+    # should keep going, looking for more lookahead due to the uncertainty.</p>
+    #
+    # <p>For simplicity, I'm doing a equality check between {@code x} and
+    # {@code x'} that lets the algorithm continue to consume lookahead longer
+    # than necessary. The reason I like the equality is of course the
+    # simplicity but also because that is the test you need to detect the
+    # alternatives that are actually in conflict.</p>
+    #
+    # <p><strong>CONTINUE/STOP RULE</strong></p>
+    #
+    # <p>Continue if union of resolved alternative sets from non-conflicting and
+    # conflicting alternative subsets has more than one alternative. We are
+    # uncertain about which alternative to predict.</p>
+    #
+    # <p>The complete set of alternatives, {@code [i for (_,i,_)]}, tells us which
+    # alternatives are still in the running for the amount of input we've
+    # consumed at this point. The conflicting sets let us to strip away
+    # configurations that won't lead to more states because we resolve
+    # conflicts to the configuration with a minimum alternate for the
+    # conflicting set.</p>

+#  a stack of states, tracking the closure operations as they
+#  jump from rule to rule, emulating rule invocations (method calls).
+#  I have to add a stack to simulate the proper lookahead sequences for
+#  the underlying LL grammar from which the ATN was derived.
+#
+#  <p>I use a set of ATNConfig objects not simple states.  An ATNConfig

+    # sync : {consume to what can follow sync} ;
+    # </pre>

+    # At the start of a sub rule upon error, {@link #sync} performs single
+    # token deletion, if possible. If it can't do that, it bails on the current
+    # rule and uses the default error recovery, which consumes until the
+    # resynchronization set of the current rule.
+    #
+    # <p>If the sub rule is optional ({@code (...)?}, {@code (...)*}, or block
+    # with an empty alternative), then the expected set includes what follows
+    # the subrule.</p>
+    #
+    # <p>During loop iteration, it consumes until it sees a token that can start a
+    # sub rule or what follows loop. Yes, that is pretty aggressive. We opt to
+    # stay in the loop as long as possible.</p>
+    #
+    # <p><strong>ORIGINS</strong></p>
+    #
+    # <p>Previous versions of ANTLR did a poor job of their recovery within loops.

+    # member definition of the current class.
+    #
+    # <p>This functionality cost a little bit of effort because the parser has to

+    # the parser returns from the nested call to {@code expr}, it will have
+    # call chain:</p>
+    #
+    # <pre>
+    # stat &rarr; expr &rarr; atom
+    # </pre>
+    #
+    # and it will be trying to match the {@code ')'} at this point in the
+    # derivation:
+    #
+    # <pre>
+    # =&gt; ID '=' '(' INT ')' ('+' atom)* ';'
+    #                    ^
+    # </pre>
+    #
+    # The attempt to match {@code ')'} will fail when it sees {@code ';'} and
+    # call {@link #recoverInline}. To recover, it sees that {@code LA(1)==';'}
+    # is in the set of tokens that can follow the {@code ')'} token reference
+    # in rule {@code atom}. It can assume that you forgot the {@code ')'}.

+    #  computing FIRST of what follows the rule reference in the
+    #  enclosing rule. See LinearApproximator.FIRST().
+    #  This local follow set only includes tokens
+    #  from within the rule; i.e., the FIRST computation done by
+    #  ANTLR stops at the end of a rule.
+    #
+    #  EXAMPLE
+    #
+    #  When you find a "no viable alt exception", the input is not
+    #  consistent with any of the alternatives for rule r.  The best
+    #  thing to do is to consume tokens until you see something that
+    #  can legally follow a call to r#or* any rule that called r.
+    #  You don't want the exact set of viable next tokens because the
+    #  input might just be missing a token--you might consume the
+    #  rest of the input looking for one of the missing tokens.
+    #
+    #  Consider grammar:
+    #
+    #  a : '[' b ']'
+    #    | '(' b ')'
+    #    ;
+    #  b : c '^' INT ;
+    #  c : ID
+    #    | INT
+    #    ;
+    #
+    #  At each rule invocation, the set of tokens that could follow
+    #  that rule is pushed on a stack.  Here are the various
+    #  context-sensitive follow sets:
+    #
+    #  FOLLOW(b1_in_a) = FIRST(']') = ']'
+    #  FOLLOW(b2_in_a) = FIRST(')') = ')'
+    #  FOLLOW(c_in_b) = FIRST('^') = '^'
+    #
+    #  Upon erroneous input "[]", the call chain is
+    #
+    #  a -> b -> c
+    #
+    #  and, hence, the follow context stack is:
+    #
+    #  depth     follow set       start of rule execution
+    #    0         <EOF>                    a (from main())
+    #    1          ']'                     b
+    #    2          '^'                     c
+    #
+    #  Notice that ')' is not included, because b would have to have
+    #  been called from a different context in rule a for ')' to be
+    #  included.
+    #
+    #  For error recovery, we cannot consider FOLLOW(c)
+    #  (context-sensitive or otherwise).  We need the combined set of
+    #  all context-sensitive FOLLOW sets--the set of all tokens that
+    #  could follow any reference in the call chain.  We need to
+    #  resync to one of those tokens.  Note that FOLLOW(c)='^' and if
+    #  we resync'd to that token, we'd consume until EOF.  We need to
+    #  sync to context-sensitive FOLLOWs for a, b, and c: {']','^'}.
+    #  In this case, for input "[]", LA(1) is ']' and in the set, so we would
+    #  not consume anything. After printing an error, rule c would
+    #  return normally.  Rule b would not find the required '^' though.
+    #  At this point, it gets a mismatched token error and throws an
+    #  exception (since LA(1) is not in the viable following token
+    #  set).  The rule exception handler tries to recover, but finds
+    #  the same recovery set and doesn't consume anything.  Rule b
+    #  exits normally returning to rule a.  Now it finds the ']' (and
+    #  with the successful match exits errorRecovery mode).
+    #
+    #  So, you can see that the parser walks up the call chain looking
+    #  for the token that was a member of the recovery set.
+    #
+    #  Errors are not generated in errorRecovery mode.
+    #
+    #  ANTLR's error recovery mechanism is based upon original ideas:
+    #
+    #  "Algorithms + Data Structures = Programs" by Niklaus Wirth
+    #
+    #  and
+    #

+    #  "Efficient and Comfortable Error Recovery in Recursive Descent
+    #  Parsers":
+    #  ftp:#www.cocolab.com/products/cocktail/doca4.ps/ell.ps.zip
+    #
+    #  Like Grosch I implement context-sensitive FOLLOW sets that are combined
+    #  at run-time upon error to avoid overhead during parsing.

+# A tree pattern matching mechanism for ANTLR {@link ParseTree}s.
+#
+# <p>Patterns are strings of source input text with special tags representing
+# token or rule references such as:</p>
+#
+# <p>{@code <ID> = <expr>;}</p>
+#
+# <p>Given a pattern start rule such as {@code statement}, this object constructs
+# a {@link ParseTree} with placeholders for the {@code ID} and {@code expr}
+# subtree. Then the {@link #match} routines can compare an actual
+# {@link ParseTree} from a parse with this pattern. Tag {@code <ID>} matches
+# any {@code ID} token and tag {@code <expr>} references the result of the
+# {@code expr} rule (generally an instance of {@code ExprContext}.</p>
+#
+# <p>Pattern {@code x = 0;} is a similar pattern that matches the same pattern
+# except that it requires the identifier to be {@code x} and the expression to
+# be {@code 0}.</p>
+#
+# <p>The {@link #matches} routines return {@code true} or {@code false} based
+# upon a match for the tree rooted at the parameter sent in. The
+# {@link #match} routines return a {@link ParseTreeMatch} object that
+# contains the parse tree, the parse tree pattern, and a map from tag name to
+# matched nodes (more below). A subtree that fails to match, returns with
+# {@link ParseTreeMatch#mismatchedNode} set to the first tree node that did not
+# match.</p>
+#
+# <p>For efficiency, you can compile a tree pattern in string form to a
+# {@link ParseTreePattern} object.</p>
+#
+# <p>See {@code TestParseTreeMatcher} for lots of examples.
+# {@link ParseTreePattern} has two static helper methods:
+# {@link ParseTreePattern#findAll} and {@link ParseTreePattern#match} that
+# are easy to use but not super efficient because they create new
+# {@link ParseTreePatternMatcher} objects each time and have to compile the
+# pattern in string form before using it.</p>
+#
+# <p>The lexer and parser that you pass into the {@link ParseTreePatternMatcher}
+# constructor are used to parse the pattern in string form. The lexer converts
+# the {@code <ID> = <expr>;} into a sequence of four tokens (assuming lexer
+# throws out whitespace or puts it on a hidden channel). Be aware that the
+# input stream is reset for the lexer (but not the parser; a
+# {@link ParserInterpreter} is created to parse the input.). Any user-defined
+# fields you have put into the lexer might get changed when this mechanism asks
+# it to scan the pattern string.</p>
+#
+# <p>Normally a parser does not accept token {@code <expr>} as a valid
+# {@code expr} but, from the parser passed in, we create a special version of
+# the underlying grammar representation (an {@link ATN}) that allows imaginary
+# tokens representing rules ({@code <expr>}) to match entire rules. We call
+# these <em>bypass alternatives</em>.</p>
+#
+# <p>Delimiters are {@code <} and {@code >}, with {@code \} as the escape string
+# by default, but you can set them to whatever you want using
+# {@link #setDelimiters}. You must escape both start and stop strings
+# {@code \<} and {@code \>}.</p>

+
+AnyIO is an asynchronous networking and concurrency library that works on top of either asyncio_ or
+Trio_. It implements Trio-like `structured concurrency`_ (SC) on top of asyncio and works in harmony
+with the native SC of Trio itself.
+
+Applications and libraries written against AnyIO's API will run unmodified on either asyncio_ or
+Trio_. AnyIO can also be adopted into a library or application incrementally – bit by bit, no full
+refactoring necessary. It will blend in with the native libraries of your chosen backend.
+
+To find out why you might want to use AnyIO's APIs instead of asyncio's, you can read about it
+`here <https://anyio.readthedocs.io/en/stable/why.html>`_.

+
+Features
+--------
+
+AnyIO offers the following functionality:
+
+* Task groups (nurseries_ in trio terminology)
+* High-level networking (TCP, UDP and UNIX sockets)
+
+  * `Happy eyeballs`_ algorithm for TCP connections (more robust than that of asyncio on Python
+    3.8)
+  * async/await style UDP sockets (unlike asyncio where you still have to use Transports and
+    Protocols)
+
+* A versatile API for byte streams and object streams
+* Inter-task synchronization and communication (locks, conditions, events, semaphores, object
+  streams)
+* Worker threads
+* Subprocesses
+* Subinterpreter support for code parallelization (on Python 3.13 and later)
+* Asynchronous file I/O (using worker threads)
+* Signal handling
+* Asynchronous version of the functools_ module
+
+AnyIO also comes with its own pytest_ plugin which also supports asynchronous fixtures.
+It even works with the popular Hypothesis_ library.

+
+asyncio-compatible timeout context manager.
+
+
+
+DEPRECATED
+----------
+
+This library has effectively been upstreamed into Python 3.11+.
+
+Therefore this library is considered deprecated and no longer actively supported.
+
+Version 5.0+ provides dual-mode when executed on Python 3.11+:
+``asyncio_timeout.Timeout`` is fully compatible with ``asyncio.Timeout`` *and* old
+versions of the library.
+
+Anyway, using upstream is highly recommended. ``asyncio_timeout`` exists only for the
+sake of backward compatibility, easy supporting both old and new Python by the same
+code, and easy misgration.
+
+If rescheduling API is not important and only ``async with timeout(...): ...`` functionality is required,
+a user could apply conditional import::
+
+    if sys.version_info >= (3, 11):
+        from asyncio import timeout, timeout_at
+    else:
+        from async_timeout import timeout, timeout_at
+
+
+Usage example
+-------------
+
+
+The context manager is useful in cases when you want to apply timeout
+logic around block of code or in cases when ``asyncio.wait_for()`` is
+not suitable. Also it's much faster than ``asyncio.wait_for()``
+because ``timeout`` doesn't create a new task.
+
+The ``timeout(delay, *, loop=None)`` call returns a context manager
+that cancels a block on *timeout* expiring::
+
+   from async_timeout import timeout
+   async with timeout(1.5):
+       await inner()
+
+1. If ``inner()`` is executed faster than in ``1.5`` seconds nothing
+   happens.
+2. Otherwise ``inner()`` is cancelled internally by sending
+   ``asyncio.CancelledError`` into but ``asyncio.TimeoutError`` is
+   raised outside of context manager scope.
+
+*timeout* parameter could be ``None`` for skipping timeout functionality.
+
+
+Alternatively, ``timeout_at(when)`` can be used for scheduling
+at the absolute time::
+
+   loop = asyncio.get_event_loop()
+   now = loop.time()
+
+   async with timeout_at(now + 1.5):
+       await inner()
+
+
+Please note: it is not POSIX time but a time with
+undefined starting base, e.g. the time of the system power on.
+
+
+Context manager has ``.expired()`` / ``.expired`` for check if timeout happens
+exactly in context manager::
+
+   async with timeout(1.5) as cm:
+       await inner()
+   print(cm.expired())  # recommended api
+   print(cm.expired)    # compatible api
+
+The property is ``True`` if ``inner()`` execution is cancelled by
+timeout context manager.
+
+If ``inner()`` call explicitly raises ``TimeoutError`` ``cm.expired``
+is ``False``.
+
+The scheduled deadline time is available as ``.when()`` / ``.deadline``::
+
+   async with timeout(1.5) as cm:
+       cm.when()    # recommended api
+       cm.deadline  # compatible api
+
+Not finished yet timeout can be rescheduled by ``shift()``
+or ``update()`` methods::
+
+   async with timeout(1.5) as cm:
+       # recommended api
+       cm.reschedule(cm.when() + 1)  # add another second on waiting
+       # compatible api
+       cm.shift(1)  # add another second on waiting
+       cm.update(loop.time() + 5)  # reschedule to now+5 seconds
+
+Rescheduling is forbidden if the timeout is expired or after exit from ``async with``
+code block.
+
+
+Disable scheduled timeout::
+
+   async with timeout(1.5) as cm:
+       cm.reschedule(None)  # recommended api
+       cm.reject()          # compatible api
+

+    A class decorator that adds :term:`dunder methods` according to
+    :term:`fields <field>` specified using :doc:`type annotations <types>`,
+    `field()` calls, or the *these* argument.
+
+    Since *attrs* patches or replaces an existing class, you cannot use
+    `object.__init_subclass__` with *attrs* classes, because it runs too early.
+    As a replacement, you can define ``__attrs_init_subclass__`` on your class.
+    It will be called by *attrs* classes that subclass it after they're
+    created. See also :ref:`init-subclass`.
+
+    Args:
+        slots (bool):
+            Create a :term:`slotted class <slotted classes>` that's more
+            memory-efficient. Slotted classes are generally superior to the
+            default dict classes, but have some gotchas you should know about,
+            so we encourage you to read the :term:`glossary entry <slotted
+            classes>`.
+
+        auto_detect (bool):
+            Instead of setting the *init*, *repr*, *eq*, and *hash* arguments
+            explicitly, assume they are set to True **unless any** of the
+            involved methods for one of the arguments is implemented in the
+            *current* class (meaning, it is *not* inherited from some base
+            class).
+
+            So, for example by implementing ``__eq__`` on a class yourself,
+            *attrs* will deduce ``eq=False`` and will create *neither*
+            ``__eq__`` *nor* ``__ne__`` (but Python classes come with a
+            sensible ``__ne__`` by default, so it *should* be enough to only
+            implement ``__eq__`` in most cases).
+
+            Passing :data:`True` or :data:`False` to *init*, *repr*, *eq*, or *hash*
+            overrides whatever *auto_detect* would determine.
+
+        auto_exc (bool):
+            If the class subclasses `BaseException` (which implicitly includes
+            any subclass of any exception), the following happens to behave
+            like a well-behaved Python exception class:
+
+            - the values for *eq*, *order*, and *hash* are ignored and the
+              instances compare and hash by the instance's ids [#]_ ,
+            - all attributes that are either passed into ``__init__`` or have a
+              default value are additionally available as a tuple in the
+              ``args`` attribute,
+            - the value of *str* is ignored leaving ``__str__`` to base
+              classes.
+
+            .. [#]
+               Note that *attrs* will *not* remove existing implementations of
+               ``__hash__`` or the equality methods. It just won't add own
+               ones.
+
+        on_setattr (~typing.Callable | list[~typing.Callable] | None | ~typing.Literal[attrs.setters.NO_OP]):
+            A callable that is run whenever the user attempts to set an
+            attribute (either by assignment like ``i.x = 42`` or by using
+            `setattr` like ``setattr(i, "x", 42)``). It receives the same
+            arguments as validators: the instance, the attribute that is being
+            modified, and the new value.
+
+            If no exception is raised, the attribute is set to the return value
+            of the callable.
+
+            If a list of callables is passed, they're automatically wrapped in
+            an `attrs.setters.pipe`.
+
+            If left None, the default behavior is to run converters and
+            validators whenever an attribute is set.
+
+        init (bool):
+            Create a ``__init__`` method that initializes the *attrs*
+            attributes. Leading underscores are stripped for the argument name,
+            unless an alias is set on the attribute.
+
+            .. seealso::
+                `init` shows advanced ways to customize the generated
+                ``__init__`` method, including executing code before and after.
+
+        repr(bool):
+            Create a ``__repr__`` method with a human readable representation
+            of *attrs* attributes.
+
+        str (bool):
+            Create a ``__str__`` method that is identical to ``__repr__``. This
+            is usually not necessary except for `Exception`\ s.
+
+        eq (bool | None):
+            If True or None (default), add ``__eq__`` and ``__ne__`` methods
+            that check two instances for equality.
+
+            .. seealso::
+                `comparison` describes how to customize the comparison behavior
+                going as far comparing NumPy arrays.
+
+        order (bool | None):
+            If True, add ``__lt__``, ``__le__``, ``__gt__``, and ``__ge__``
+            methods that behave like *eq* above and allow instances to be
+            ordered.
+
+            They compare the instances as if they were tuples of their *attrs*
+            attributes if and only if the types of both classes are
+            *identical*.
+
+            If `None` mirror value of *eq*.
+
+            .. seealso:: `comparison`
+
+        unsafe_hash (bool | None):
+            If None (default), the ``__hash__`` method is generated according
+            how *eq* and *frozen* are set.
+
+            1. If *both* are True, *attrs* will generate a ``__hash__`` for
+               you.
+            2. If *eq* is True and *frozen* is False, ``__hash__`` will be set
+               to None, marking it unhashable (which it is).
+            3. If *eq* is False, ``__hash__`` will be left untouched meaning
+               the ``__hash__`` method of the base class will be used. If the
+               base class is `object`, this means it will fall back to id-based
+               hashing.
+
+            Although not recommended, you can decide for yourself and force
+            *attrs* to create one (for example, if the class is immutable even
+            though you didn't freeze it programmatically) by passing True or
+            not.  Both of these cases are rather special and should be used
+            carefully.
+
+            .. seealso::
+
+                - Our documentation on `hashing`,
+                - Python's documentation on `object.__hash__`,
+                - and the `GitHub issue that led to the default \ behavior
+                  <https://github.com/python-attrs/attrs/issues/136>`_ for more
+                  details.
+
+        hash (bool | None):
+            Deprecated alias for *unsafe_hash*. *unsafe_hash* takes precedence.
+
+        cache_hash (bool):
+            Ensure that the object's hash code is computed only once and stored
+            on the object.  If this is set to True, hashing must be either
+            explicitly or implicitly enabled for this class.  If the hash code
+            is cached, avoid any reassignments of fields involved in hash code
+            computation or mutations of the objects those fields point to after
+            object creation.  If such changes occur, the behavior of the
+            object's hash code is undefined.
+
+        frozen (bool):
+            Make instances immutable after initialization.  If someone attempts
+            to modify a frozen instance, `attrs.exceptions.FrozenInstanceError`
+            is raised.
+
+            .. note::
+
+                1. This is achieved by installing a custom ``__setattr__``
+                   method on your class, so you can't implement your own.
+
+                2. True immutability is impossible in Python.
+
+                3. This *does* have a minor a runtime performance `impact
+                   <how-frozen>` when initializing new instances.  In other
+                   words: ``__init__`` is slightly slower with ``frozen=True``.
+
+                4. If a class is frozen, you cannot modify ``self`` in
+                   ``__attrs_post_init__`` or a self-written ``__init__``. You
+                   can circumvent that limitation by using
+                   ``object.__setattr__(self, "attribute_name", value)``.
+
+                5. Subclasses of a frozen class are frozen too.
+
+        kw_only (bool):
+            Make attributes keyword-only in the generated ``__init__`` (if
+            *init* is False, this parameter is ignored).  Attributes that
+            explicitly set ``kw_only=False`` are not affected; base class
+            attributes are also not affected.
+
+            Also see *force_kw_only*.
+
+        weakref_slot (bool):
+            Make instances weak-referenceable.  This has no effect unless
+            *slots* is True.
+
+        field_transformer (~typing.Callable | None):
+            A function that is called with the original class object and all
+            fields right before *attrs* finalizes the class.  You can use this,
+            for example, to automatically add converters or validators to
+            fields based on their types.
+
+            .. seealso:: `transform-fields`
+
+        match_args (bool):
+            If True (default), set ``__match_args__`` on the class to support
+            :pep:`634` (*Structural Pattern Matching*). It is a tuple of all
+            non-keyword-only ``__init__`` parameter names on Python 3.10 and
+            later. Ignored on older Python versions.
+
+        collect_by_mro (bool):
+            If True, *attrs* collects attributes from base classes correctly
+            according to the `method resolution order
+            <https://docs.python.org/3/howto/mro.html>`_. If False, *attrs*
+            will mimic the (wrong) behavior of `dataclasses` and :pep:`681`.
+
+            See also `issue #428
+            <https://github.com/python-attrs/attrs/issues/428>`_.
+
+        force_kw_only (bool):
+            A back-compat flag for restoring pre-25.4.0 behavior.  If True and
+            ``kw_only=True``, all attributes are made keyword-only, including
+            base class attributes, and those set to ``kw_only=False`` at the
+            attribute level.  Defaults to False.
+
+            See also `issue #980
+            <https://github.com/python-attrs/attrs/issues/980>`_.
+
+        getstate_setstate (bool | None):
+            .. note::
+
+                This is usually only interesting for slotted classes and you
+                should probably just set *auto_detect* to True.
+
+            If True, ``__getstate__`` and ``__setstate__`` are generated and
+            attached to the class. This is necessary for slotted classes to be
+            pickleable. If left None, it's True by default for slotted classes
+            and False for dict classes.
+
+            If *auto_detect* is True, and *getstate_setstate* is left None, and
+            **either** ``__getstate__`` or ``__setstate__`` is detected
+            directly on the class (meaning: not inherited), it is set to False
+            (this is usually what you want).
+
+        auto_attribs (bool | None):
+            If True, look at type annotations to determine which attributes to
+            use, like `dataclasses`. If False, it will only look for explicit
+            :func:`field` class attributes, like classic *attrs*.
+
+            If left None, it will guess:
+
+            1. If any attributes are annotated and no unannotated
+               `attrs.field`\ s are found, it assumes *auto_attribs=True*.
+            2. Otherwise it assumes *auto_attribs=False* and tries to collect
+               `attrs.field`\ s.
+
+            If *attrs* decides to look at type annotations, **all** fields
+            **must** be annotated. If *attrs* encounters a field that is set to
+            a :func:`field` / `attr.ib` but lacks a type annotation, an
+            `attrs.exceptions.UnannotatedAttributeError` is raised.  Use
+            ``field_name: typing.Any = field(...)`` if you don't want to set a
+            type.
+
+            .. warning::
+
+                For features that use the attribute name to create decorators
+                (for example, :ref:`validators <validators>`), you still *must*
+                assign :func:`field` / `attr.ib` to them. Otherwise Python will
+                either not find the name or try to use the default value to
+                call, for example, ``validator`` on it.
+
+            Attributes annotated as `typing.ClassVar`, and attributes that are
+            neither annotated nor set to an `field()` are **ignored**.
+
+        these (dict[str, object]):
+            A dictionary of name to the (private) return value of `field()`
+            mappings. This is useful to avoid the definition of your attributes
+            within the class body because you can't (for example, if you want
+            to add ``__repr__`` methods to Django models) or don't want to.
+
+            If *these* is not `None`, *attrs* will *not* search the class body
+            for attributes and will *not* remove any attributes from it.
+
+            The order is deduced from the order of the attributes inside
+            *these*.
+
+            Arguably, this is a rather obscure feature.
+
+    .. versionadded:: 20.1.0
+    .. versionchanged:: 21.3.0 Converters are also run ``on_setattr``.
+    .. versionadded:: 22.2.0
+       *unsafe_hash* as an alias for *hash* (for :pep:`681` compliance).
+    .. versionchanged:: 24.1.0
+       Instances are not compared as tuples of attributes anymore, but using a
+       big ``and`` condition. This is faster and has more correct behavior for
+       uncomparable values like `math.nan`.
+    .. versionadded:: 24.1.0
+       If a class has an *inherited* classmethod called
+       ``__attrs_init_subclass__``, it is executed after the class is created.
+    .. deprecated:: 24.1.0 *hash* is deprecated in favor of *unsafe_hash*.
+    .. versionadded:: 24.3.0
+       Unless already present, a ``__replace__`` method is automatically
+       created for `copy.replace` (Python 3.13+ only).
+    .. versionchanged:: 25.4.0
+       *kw_only* now only applies to attributes defined in the current class,
+       and respects attribute-level ``kw_only=False`` settings.
+    .. versionadded:: 25.4.0
+       Added *force_kw_only* to go back to the previous *kw_only* behavior.
+
+    .. note::
+
+        The main differences to the classic `attr.s` are:
+
+        - Automatically detect whether or not *auto_attribs* should be `True`
+          (c.f. *auto_attribs* parameter).
+        - Converters and validators run when attributes are set by default --
+          if *frozen* is `False`.
+        - *slots=True*
+
+          Usually, this has only upsides and few visible effects in everyday
+          programming. But it *can* lead to some surprising behaviors, so
+          please make sure to read :term:`slotted classes`.
+
+        - *auto_exc=True*
+        - *auto_detect=True*
+        - *order=False*
+        - *force_kw_only=False*
+        - Some options that were only relevant on Python 2 or were kept around
+          for backwards-compatibility have been removed.

+            Callable that is called by *attrs*-generated ``__init__`` methods
+            after the instance has been initialized.  They receive the
+            initialized instance, the :func:`~attrs.Attribute`, and the passed
+            value.
+
+            The return value is *not* inspected so the validator has to throw
+            an exception itself.
+
+            If a `list` is passed, its items are treated as validators and must
+            all pass.
+
+            Validators can be globally disabled and re-enabled using

+            Include this attribute in the generated ``__repr__`` method. If
+            True, include the attribute; if False, omit it. By default, the
+            built-in ``repr()`` function is used. To override how the attribute
+            value is formatted, pass a ``callable`` that takes a single value
+            and returns a string. Note that the resulting string is used as-is,
+            which means it will be used directly *instead* of calling
+            ``repr()`` (the default).
+
+        eq (bool | ~typing.Callable):
+            If True (default), include this attribute in the generated
+            ``__eq__`` and ``__ne__`` methods that check two instances for
+            equality. To override how the attribute value is compared, pass a
+            callable that takes a single value and returns the value to be
+            compared.
+
+            .. seealso:: `comparison`
+
+        order (bool | ~typing.Callable):
+            If True (default), include this attributes in the generated
+            ``__lt__``, ``__le__``, ``__gt__`` and ``__ge__`` methods. To
+            override how the attribute value is ordered, pass a callable that
+            takes a single value and returns the value to be ordered.
+
+            .. seealso:: `comparison`
+
+        hash (bool | None):
+            Include this attribute in the generated ``__hash__`` method.  If
+            None (default), mirror *eq*'s value.  This is the correct behavior
+            according the Python spec.  Setting this value to anything else
+            than None is *discouraged*.
+
+            .. seealso:: `hashing`
+
+        init (bool):
+            Include this attribute in the generated ``__init__`` method.
+
+            It is possible to set this to False and set a default value. In
+            that case this attributed is unconditionally initialized with the
+            specified default value or factory.
+
+            .. seealso:: `init`
+
+        converter (typing.Callable | Converter):
+            A callable that is called by *attrs*-generated ``__init__`` methods
+            to convert attribute's value to the desired format.
+
+            If a vanilla callable is passed, it is given the passed-in value as
+            the only positional argument. It is possible to receive additional
+            arguments by wrapping the callable in a `Converter`.
+
+            Either way, the returned value will be used as the new value of the
+            attribute.  The value is converted before being passed to the
+            validator, if any.
+
+            .. seealso:: :ref:`converters`
+
+        metadata (dict | None):

+
+            .. seealso:: `extending-metadata`.
+
+        type (type):
+            The type of the attribute. Nowadays, the preferred method to
+            specify the type is using a variable annotation (see :pep:`526`).
+            This argument is provided for backwards-compatibility and for usage
+            with `make_class`. Regardless of the approach used, the type will
+            be stored on ``Attribute.type``.
+
+            Please note that *attrs* doesn't do anything with this metadata by
+            itself. You can use it as part of your own code or for `static type
+            checking <types>`.
+
+        kw_only (bool | None):
+            Make this attribute keyword-only in the generated ``__init__`` (if
+            *init* is False, this parameter is ignored).  If None (default),
+            mirror the setting from `attrs.define`.
+
+        on_setattr (~typing.Callable | list[~typing.Callable] | None | ~typing.Literal[attrs.setters.NO_OP]):
+            Allows to overwrite the *on_setattr* setting from `attr.s`. If left
+            None, the *on_setattr* value from `attr.s` is used. Set to
+            `attrs.setters.NO_OP` to run **no** `setattr` hooks for this
+            attribute -- regardless of the setting in `define()`.
+
+        alias (str | None):
+            Override this attribute's parameter name in the generated
+            ``__init__`` method. If left None, default to ``name`` stripped
+            of leading underscores. See `private-attributes`.

+
+*attrs* is the Python package that will bring back the **joy** of **writing classes** by relieving you from the drudgery of implementing object protocols (aka [dunder methods](https://www.attrs.org/en/latest/glossary.html#term-dunder-methods)).
+Trusted by NASA for [Mars missions since 2020](https://github.com/readme/featured/nasa-ingenuity-helicopter)!
+
+Its main goal is to help you to write **concise** and **correct** software without slowing down your code.
+
+

+</p>
+
+<!-- teaser-end -->
+
+## Example
+
+*attrs* gives you a class decorator and a way to declaratively define the attributes on that class:
+
+<!-- code-begin -->
+
+```pycon
+>>> from attrs import asdict, define, make_class, Factory
+
+>>> @define
+... class SomeClass:
+...     a_number: int = 42
+...     list_of_numbers: list[int] = Factory(list)
+...
+...     def hard_math(self, another_number):
+...         return self.a_number + sum(self.list_of_numbers) * another_number
+
+
+>>> sc = SomeClass(1, [1, 2, 3])
+>>> sc
+SomeClass(a_number=1, list_of_numbers=[1, 2, 3])
+
+>>> sc.hard_math(3)
+19
+>>> sc == SomeClass(1, [1, 2, 3])
+True
+>>> sc != SomeClass(2, [3, 2, 1])
+True
+
+>>> asdict(sc)
+{'a_number': 1, 'list_of_numbers': [1, 2, 3]}
+
+>>> SomeClass()
+SomeClass(a_number=42, list_of_numbers=[])
+
+>>> C = make_class("C", ["a", "b"])
+>>> C("foo", "bar")
+C(a='foo', b='bar')
+```
+
+After *declaring* your attributes, *attrs* gives you:
+
+- a concise and explicit overview of the class's attributes,
+- a nice human-readable `__repr__`,
+- equality-checking methods,
+- an initializer,
+- and much more,
+
+*without* writing dull boilerplate code again and again and *without* runtime performance penalties.
+
+---
+
+This example uses *attrs*'s modern APIs that have been introduced in version 20.1.0, and the *attrs* package import name that has been added in version 21.3.0.
+The classic APIs (`@attr.s`, `attr.ib`, plus their serious-business aliases) and the `attr` package import name will remain **indefinitely**.
+
+Check out [*On The Core API Names*](https://www.attrs.org/en/latest/names.html) for an in-depth explanation!
+
+
+### Hate Type Annotations!?
+
+No problem!
+Types are entirely **optional** with *attrs*.
+Simply assign `attrs.field()` to the attributes instead of annotating them with types:
+
+```python
+from attrs import define, field
+
+@define
+class SomeClass:
+    a_number = field(default=42)
+    list_of_numbers = field(factory=list)
+```
+
+
+## Data Classes
+
+On the tin, *attrs* might remind you of `dataclasses` (and indeed, `dataclasses` [are a descendant](https://hynek.me/articles/import-attrs/) of *attrs*).
+In practice it does a lot more and is more flexible.
+For instance, it allows you to define [special handling of NumPy arrays for equality checks](https://www.attrs.org/en/stable/comparison.html#customization), allows more ways to [plug into the initialization process](https://www.attrs.org/en/stable/init.html#hooking-yourself-into-initialization), has a replacement for `__init_subclass__`, and allows for stepping through the generated methods using a debugger.
+
+For more details, please refer to our [comparison page](https://www.attrs.org/en/stable/why.html#data-classes), but generally speaking, we are more likely to commit crimes against nature to make things work that one would expect to work, but that are quite complicated in practice.

+
+## Release Information
+
+### Backwards-incompatible Changes
+
+- Class-level `kw_only=True` behavior is now consistent with `dataclasses`.
+
+  Previously, a class that sets `kw_only=True` makes all attributes keyword-only, including those from base classes.
+  If an attribute sets `kw_only=False`, that setting is ignored, and it is still made keyword-only.
+
+  Now, only the attributes defined in that class that doesn't explicitly set `kw_only=False` are made keyword-only.
+
+  This shouldn't be a problem for most users, unless you have a pattern like this:
+
+  ```python
+  @attrs.define(kw_only=True)
+  class Base:
+      a: int
+      b: int = attrs.field(default=1, kw_only=False)
+
+  @attrs.define
+  class Subclass(Base):
+      c: int
+  ```
+
+  Here, we have a `kw_only=True` *attrs* class (`Base`) with an attribute that sets `kw_only=False` and has a default (`Base.b`), and then create a subclass (`Subclass`) with required arguments (`Subclass.c`).
+  Previously this would work, since it would make `Base.b` keyword-only, but now this fails since `Base.b` is positional, and we have a required positional argument (`Subclass.c`) following another argument with defaults.
+  [#1457](https://github.com/python-attrs/attrs/issues/1457)
+
+
+### Changes
+
+- Values passed to the `__init__()` method of `attrs` classes are now correctly passed to `__attrs_pre_init__()` instead of their default values (in cases where *kw_only* was not specified).
+  [#1427](https://github.com/python-attrs/attrs/issues/1427)
+- Added support for Python 3.14 and [PEP 749](https://peps.python.org/pep-0749/).
+  [#1446](https://github.com/python-attrs/attrs/issues/1446),
+  [#1451](https://github.com/python-attrs/attrs/issues/1451)
+- `attrs.validators.deep_mapping()` now allows to leave out either *key_validator* xor *value_validator*.
+  [#1448](https://github.com/python-attrs/attrs/issues/1448)
+- `attrs.validators.deep_iterator()` and `attrs.validators.deep_mapping()` now accept lists and tuples for all validators and wrap them into a `attrs.validators.and_()`.
+  [#1449](https://github.com/python-attrs/attrs/issues/1449)
+- Added a new **experimental** way to inspect classes:
+
+  `attrs.inspect(cls)` returns the _effective_ class-wide parameters that were used by *attrs* to construct the class.
+
+  The returned class is the same data structure that *attrs* uses internally to decide how to construct the final class.
+  [#1454](https://github.com/python-attrs/attrs/issues/1454)
+- Fixed annotations for `attrs.field(converter=...)`.
+  Previously, a `tuple` of converters was only accepted if it had exactly one element.
+  [#1461](https://github.com/python-attrs/attrs/issues/1461)
+- The performance of `attrs.asdict()` has been improved by 45–260%.
+  [#1463](https://github.com/python-attrs/attrs/issues/1463)
+- The performance of `attrs.astuple()` has been improved by 49–270%.
+  [#1469](https://github.com/python-attrs/attrs/issues/1469)
+- The type annotation for `attrs.validators.or_()` now allows for different types of validators.
+
+  This was only an issue on Pyright.
+  [#1474](https://github.com/python-attrs/attrs/issues/1474)

+# Backgrounds
+
+![backgrounds](https://www.news-world.us/wp-content/uploads/2015/02/Stone-and-wall-backgrounds-3.jpg)
+
+## 介绍
+
+backgrounds 是公司内通用的异步刷新任务，目的是为了解决多个库分别创建后台线程造成资源浪费，以及使用 fork 的 server 中，容易有主线程中创建后台线程，fork 之后的子进程没有，造成业务受损。
+
+将来还可能利用 Python 提供的单进程多解释器模型，提供真正的并发能力去执行这些后台任务。
+
+### 节省资源
+
+很多库需要有后台刷新机制，包括不限于：
+
+- servicediscovery(consul)：定期刷新服务地址
+- metrics：后台异步发送数据
+- 流式日志：后台异步发送数据
+- TCC：后台刷新配置
+- kafka：后台刷新集群拓扑
+
+有这类需求的库理论上后续会越来越多，如果每个库都有自己的后台线程，一个依赖这些库的服务如果有数十个 worker 进程，很容易导致服务中出现上百个线程，造成不必要的内存浪费。
+
+### 提升性能
+
+[PEP 554](https://www.python.org/dev/peps/pep-0554/) 中提出了 Python 的“单进程多解释器”模型，可以在一个进程中启动多个解释器，并且每个解释器实例有自己单独的 GIL，不同的解释器可以“真正的并发”，CPU bound 的任务可以同时执行。
+
+Python3.8 中对此已经有了初步支持，3.9 中会正式引入此特性。后续本库可以将目前的后台线程，改为“后台解释器实例”，并且隐藏相关细节，即可让所有接入的库不修改代码的情况下获得收益。
+
+### fork 与多线程的问题
+
+Unix 环境下，fork 的时候子进程会继承会父进程的大部分资源，但是线程不在此列。
+
+因此需要创建后台线程的库，很容易因为用户在主进程做了库的初始化工作（其中包括创建线程），造成worker 子线程中丢失后台线程，数据不刷新，引发生产环境事故。
+
+虽然可以让库本身和用户做好约定，只在 worker 进程中执行初始化，但是这给库的使用者造成了很大的心智负担。并且库的编写者也容易因为不了解这点，造成潜在问题。
+
+使用 backgrounds 库的话，只需要 backgrounds 库和用户使用的框架（Euler、BytedUnicorn 等）做好约定，在框架的 fork 之后再调用 `backgrounds.start()`，这样对于库的编写者、使用者来说，使用上就不需要有任何心智负担，只需要框架编写者（目前公司内的框架并不是很多）来解决这个问题。
+
+## 开发
+
+* 使用 `$ virtualenv venv --python=python3 && source venv/bin/activate` 创建并激活此 `virtualenv`;
+* 使用 `$ make install_dev` 或者`$ pip install -e .[dev]` 安装项目依赖
+* Coding 🍻
+
+
+
+## 静态检查
+
+项目已经配置好使用 `flake8` 做静态检查，执行`$ make lint`即可。
+
+
+
+## 测试
+
+单元测试位于 `tests/` 目录中，使用 `$ make test` 可以运行单元测试。如何编写单元测试可以参考 [pytest](https://github.com/pytest-dev/pytest) 
+
+默认会在 Python2.7/3.7 环境下运行单元测试，如果需要支持更多版本 Python，可以修改 `tox.ini`。
+
+
+
+## 规范
+
+### 代码规范
+
+* 需要保证代码兼容 Python2.7，Python3.5+；
+* 代码风格兼容 [PEP8](https://www.python.org/dev/peps/pep-0008/)，除了代码最大宽度放宽到 120。
+
+### 版本规范
+
+* 版本需要遵循 [Semver](https://semver.org/lang/zh-CN/)；
+* 发布分支后，需要创建类似 `v0.0.1` 的 tag；
+* 每次 Release，需要编辑 CHANGELOG.md，内容需要遵守 [changelog 规范](https://keepachangelog.com/zh-CN/1.0.0/)。
+
+
+
+## Tips
+
+### Makefile指南
+
+makefile用于帮助开发者快速使用功能，目前支持的命令有
+
+|       指令       |                             作用                             |
+| :--------------: | :----------------------------------------------------------: |
+|       make       | 按顺序执行 install_dev、isort、isort_check、lint、test(**操作更改代码!**) |
+|    make check    |       按顺序执行 install_dev、isort_check、lint、test        |
+| make install_dev |         安装测试所需依赖(位于setup.py的DEV_REQUIRES)         |
+|    make isort    |        执行isort，规范化import顺序(**操作更改代码!**)        |
+| make isort_check |                   执行import顺序规范性检查                   |
+|    make lint     |                执行flake8，检查你的代码规范性                |
+|    make test     |                执行tox，检测单元测试的正确性                 |
+|    make clean    |                      清除测试和检查产物                      |
+
+建议每次准备发布代码前，执行一次make或者make check来保证代码的规范性和健壮性。
+
+### Python2/3 兼容
+
+**每个** Python 文件头部都增加如下代码(尽量保证此import位于任何其他import之前)：
+
+```python
+# coding: utf-8
+
+from __future__ import absolute_import, division, print_function, unicode_literals
+```
+
+来保证代码在 Python2 和 Python3 下尽可能保持一致。
+
+Python2 与 Python3 不兼容的代码，尽量使用 [six](https://pythonhosted.org/six/) 模块做兼容。比如 Python2 和 Python3 下 `range` 函数行为不一致，统一使用 `six.moves.range` 可以保证兼容性。
+
+### 类型标注
+
+Python [PEP484](https://www.python.org/dev/peps/pep-0484/) 中新增了类型标注功能，可以给代码增加可选的类型标注，配合 [mypy](http://mypy-lang.org/) 可以静态的给代码做类型检查。
+
+开发中给每个 `.py` 文件编写一个对应的 `.pyi`，编写好导出类型的函数签名。此项目已经配置好相关规则，包发布后，使用者就可以使用编写好的类型信息做静态类型检查、代码补全。
+
+如果对导出函数写 docstring，除了按照 PEP8 的要求进行编写之外，还可以对传入传出数据类型做标注与注释。注释格式参考 PyCharm 的[这篇文档](https://www.jetbrains.com/help/pycharm/using-docstrings-to-specify-types.html)的格式进行编写。PyCharm 以及 Jedi（vim / emacs / vscode 都是基于 jedi 进行自动补全）等等自动补全/静态检查工具都可以基于此格式的信息进行检查，Sphinx 生成的 API doc 也可以进行识别。
+
+### editorconfig
+
+可以安装 [editorconfig](https://editorconfig.org/) 编辑器插件，保持代码一致性。此项目已经默认配置。

+
+## Usage
+
+### Server
+
+Write you IDL file:
+
+```thrift
+include "base.thrift"
+
+namespace py echo
+
+struct EchoRequest {
+    1: string Message,
+
+    255: optional base.Base Base,
+}
+
+struct EchoResponse {
+    1: string Resp,
+
+    255: base.BaseResp BaseResp,
+}
+
+service EchoService {
+    EchoResponse echo(1: EchoRequest req)
+}
+```
+
+Implement logic codes:
+
+```python
+import euler
+euler.install_thrift_import_hook()
+
+import echo_thrift
+
+
+app = euler.Server(echo_thrift.EchoService)
+
+
+@app.register('echo')
+def echo(ctx, req):
+    msg = req.Message
+    return echo_thrift.EchoResponse(Resp=msg)
+
+
+@app.use
+def logging(ctx, *args, **kwargs):
+    print('function %s is called with args: %s, kwargs: %s' % (ctx.name, args, kwargs))
+    res = ctx.next(*args, **kwargs)
+    return res
+
+
+app.run('tcp://localhost:1234')
+```
+
+### Client
+
+```python
+import euler
+euler.install_thrift_import_hook()
+
+import echo_thrift
+
+
+client = euler.Client(echo_thrift.EchoService, 'tcp://localhost:1234')
+
+
+@client.use
+def logging(ctx, *args, **kwargs):
+    print('calling function %s with args: %s, kwargs: %s' % (ctx.name, args, kwargs))
+    res = ctx.next(*args, **kwargs)
+    return res
+
+
+req = echo_thrift.EchoRequest(Message='Hello Euler!')
+print(client.echo(req))
+```
+
+
+#### With Service Discovery
+
+```python
+import euler
+euler.install_thrift_import_hook()
+
+import example_thrift
+
+
+req = example_thrift.ExampleRequest(Name='Leonhard Euler')
+client = euler.Client(example_thrift.ExampleService, target='sd://pie.rpc.svc', transport='buffered')
+print(client.Visit(req).Resp)
+```

+## 开发
+
+* 使用 `$ virtualenv venv --python=python3 && source venv/bin/activate` 创建并激活此 `virtualenv`;
+* 使用 `$ make install_dev` 或者`$ pip install -e .[dev]` 安装项目依赖
+* Coding
+
+
+
+## 静态检查
+
+项目已经配置好使用 `flake8` 做静态检查，执行`$ make lint`即可。
+
+
+
+## 测试
+
+单元测试位于 `tests/` 目录中，使用 `$ make test` 可以运行单元测试。如何编写单元测试可以参考 [pytest](https://github.com/pytest-dev/pytest) 
+
+默认会在 Python2.7/3.7 环境下运行单元测试，如果需要支持更多版本 Python，可以修改 `tox.ini`。
+
+
+
+## 规范
+
+### 代码规范
+
+* 需要保证代码兼容 Python2.7，Python3.7+；
+* 代码风格兼容 [PEP8](https://www.python.org/dev/peps/pep-0008/)，除了代码最大宽度放宽到 120。
+
+### 版本规范
+
+* 版本需要遵循 [Semver](https://semver.org/lang/zh-CN/)；
+* 发布分支后，需要创建类似 `v0.0.1` 的 tag；
+* 每次 Release，需要编辑 CHANGELOG.md，内容需要遵守 [changelog 规范](https://keepachangelog.com/zh-CN/1.0.0/)。
+
+
+
+## Tips
+
+### Makefile指南
+
+makefile用于帮助开发者快速使用功能，目前支持的命令有
+
+|       指令       |                             作用                             |
+| :--------------: | :----------------------------------------------------------: |
+|       make       | 按顺序执行 install_dev、isort、isort_check、lint、test(**操作更改代码!**) |
+|    make check    |       按顺序执行 install_dev、isort_check、lint、test        |
+| make install_dev |         安装测试所需依赖(位于setup.py的DEV_REQUIRES)         |
+|    make isort    |        执行isort，规范化import顺序(**操作更改代码!**)        |
+| make isort_check |                   执行import顺序规范性检查                   |
+|    make lint     |                执行flake8，检查你的代码规范性                |
+|    make test     |                执行tox，检测单元测试的正确性                 |
+|    make clean    |                      清除测试和检查产物                      |
+
+建议每次准备发布代码前，执行一次make或者make check来保证代码的规范性和健壮性。
+
+### Python2/3 兼容
+
+**每个** Python 文件头部都增加如下代码(尽量保证此import位于任何其他import之前)：
+
+```python
+# coding: utf-8
+
+from __future__ import absolute_import, division, print_function, unicode_literals
+```
+
+来保证代码在 Python2 和 Python3 下尽可能保持一致。
+
+Python2 与 Python3 不兼容的代码，尽量使用 [six](https://pythonhosted.org/six/) 模块做兼容。比如 Python2 和 Python3 下 `range` 函数行为不一致，统一使用 `six.moves.range` 可以保证兼容性。
+
+### 类型标注
+
+Python [PEP484](https://www.python.org/dev/peps/pep-0484/) 中新增了类型标注功能，可以给代码增加可选的类型标注，配合 [mypy](http://mypy-lang.org/) 可以静态的给代码做类型检查。
+
+开发中给每个 `.py` 文件编写一个对应的 `.pyi`，编写好导出类型的函数签名。此项目已经配置好相关规则，包发布后，使用者就可以使用编写好的类型信息做静态类型检查、代码补全。
+
+如果对导出函数写 docstring，除了按照 PEP8 的要求进行编写之外，还可以对传入传出数据类型做标注与注释。注释格式参考 PyCharm 的[这篇文档](https://www.jetbrains.com/help/pycharm/using-docstrings-to-specify-types.html)的格式进行编写。PyCharm 以及 Jedi（vim / emacs / vscode 都是基于 jedi 进行自动补全）等等自动补全/静态检查工具都可以基于此格式的信息进行检查，Sphinx 生成的 API doc 也可以进行识别。
+
+### editorconfig
+
+可以安装 [editorconfig](https://editorconfig.org/) 编辑器插件，保持代码一致性。此项目已经默认配置。

+# Metrics
+
+## Deprecated! Using `bytedance.metrics` instead!
+
+More document can be found [here](https://python.byted.org/library/metrics.html).
+
+## Development notice
+
+Current implmentation is cythonized for better performance. But some users are using old version of setuptools / pip, so
+we can not specify cython as a dependency before the setup.py running. As a result, we're committing the cythonized c
+file (`bytedmetrics/client.c`) to git. Any change to it should run `cythonize bytedmetrics/client.py`. Cython version
+should be `~=0.20` for we still support python2.
+
+A naive benchmark result with 100,000 times interation of `emit_counter` with one tag and unix domain socket:
+
+| Implementation| Result in seconds |
+| ------------- | ----------------- |
+| Pure python   | 1.85728           |
+| Cythonized    | 1.39842 (75%)     |
+
+### TBD
+
+Using `cdef` to improvement performance.

+# ZTI jwt helper
+
+This library is a convenient python library for working with [jwt-svid](https://github.com/spiffe/spiffe/blob/master/standards/JWT-SVID.md) 
+which is an jwt based format of zero trust identity in addition to the x.509 certificate based format. The
+sdk provides the high level functionality that includes:
+* Fetch the jwt-svid token string from zti-agent or from file path of SEC_TOKEN_PATH
+* Check whether a token string is a zti token or not
+
+## Build Package
+```bash 
+python3 -m pip install --upgrade build
+python3 -m build
+```
+
+## Install Package
+```bash
+python3 -m pip install dist/bytedztijwthelper-*.tar.gz
+```
+
+## Defined identity
+The legacy identity has the same content as identity defined in dps-sdk-python
+```python
+# the identity defined in the gdpr token
+class LegacyIdentity(object):
+    def __init__(self, version=0, authority=None, authority_chain=None, primary_auth_type=None, psm=None, user=None,
+                 expire_time=0, extension=None):
+        self.version = version
+        self.authority = authority
+        self.authorityChain = authority_chain
+        self.primaryAuthType = primary_auth_type
+        self.psm = psm
+        self.user = user
+        self.expireTime = expire_time
+        self.extension = extension
+```
+The new zero trust identity defined with spiffeID and an optional field LegacyID in the JWT Claims 
+which provides backward compatibility.
+```json
+{
+  "aud": [
+    "spire"
+  ],
+  "exp": 1610775154,
+  "iat": 1610775094,
+  "iss": "issuer",
+  "legid": {
+    "authority": "host",
+    "expireTime": 34,
+    "extension": {
+      "key1": "val1",
+      "key2": "val2"
+    },
+    "primaryAuthType": "PSM",
+    "psm": "a.b.c",
+    "user": "",
+    "version": 0
+  },
+  "sub": "spiffe://test.domain/ns:host/id:a.b.c"
+}
+```
+
+The "sub" field in the payload of token will be the spiffe ID which is the identity. 
+The sdk provide a helper identity to help parse information in the json format as below:
+```python
+class ZeroTrustIdentity(object):
+    def __init__(self, spiffe_id=None, expiry=None, namespace=None, region=None,
+                 vdc=None, identity=None, legacy_id=None):
+        self.spiffeID = spiffe_id
+        self.expiry = expiry
+        self.namespace = namespace
+        self.region = region
+        self.vdc = vdc
+        self.id = identity
+        self.legacyID = legacy_id
+```
+
+## Quick Start
+```shell script
+$ pip install bytedztijwthelper --index-url=http://pypi.byted.org/simple/pypi/+simple --trusted-host=pypi.byted.org
+```
+
+### Running Service on TCE
+Prerequisites:
+1. Check whether system env SEC_TOKEN_PATH has point to the token file.
+```shell script
+echo $SEC_TOKEN_PATH
+cat SEC_TOKEN_PATH
+```
+
+### Running Service on VM or Physical Nodes
+Prerequisites:
+1. Check whether zti-agent running on the host.
+```shell script
+ps aux | grep -i zti
+ls /var/run/zti-agent.sock
+```
+2. apply for an zero trust identity by create a registration entry of the service in the spire server
+
+
+## Usage Example
+To get / decode a jwt-svid token string:
+```python
+from ztijwthelper import jwt_helper, is_token_zti, ZtiJwtError
+
+try:
+    # decode legacy identity from token string
+    # if it's zti-jwt, legacy identity is translated from the zero trust identity
+    tokenStr = jwt_helper.get_jwt_svid()    
+    print(str(is_token_zti(tokenStr)))
+except ZtiJwtError as e:
+    print("fail to get token: %s" % e)
+```

+Certifi: Python SSL Certificates
+================================
+
+Certifi provides Mozilla's carefully curated collection of Root Certificates for
+validating the trustworthiness of SSL certificates while verifying the identity
+of TLS hosts. It has been extracted from the `Requests`_ project.
+
+Installation
+------------
+
+``certifi`` is available on PyPI. Simply install it with ``pip``::
+
+    $ pip install certifi
+
+Usage
+-----
+
+To reference the installed certificate authority (CA) bundle, you can use the
+built-in function::
+
+    >>> import certifi
+
+    >>> certifi.where()
+    '/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'
+
+Or from the command line::
+
+    $ python -m certifi
+    /usr/local/lib/python3.7/site-packages/certifi/cacert.pem
+
+Enjoy!
+
+.. _`Requests`: https://requests.readthedocs.io/en/master/
+
+Addition/Removal of Certificates
+--------------------------------
+
+Certifi does not support any addition/removal or other modification of the
+CA trust store content. This project is intended to provide a reliable and
+highly portable root of trust to python deployments. Look to upstream projects
+for methods to use alternate trust.

+This package contains a modified version of ca-bundle.crt:

+ca-bundle.crt -- Bundle of CA Root Certificates
+
+This is a bundle of X.509 certificates of public Certificate Authorities
+(CA). These were automatically extracted from Mozilla's root certificates
+file (certdata.txt).  This file can be found in the mozilla source tree:
+https://hg.mozilla.org/mozilla-central/file/tip/security/nss/lib/ckfw/builtins/certdata.txt
+It contains the certificates in PEM format and therefore

+an Apache+mod_ssl webserver for SSL client authentication.
+Just configure this file as the SSLCACertificateFile.#

+Testing/development tips
+------------------------
+
+After `git clone` or `wget && tar`, we will get a directory called `cffi` or `cffi-x.x.x`. we call it `repo-directory`. To run tests under CPython, run the following in the `repo-directory`:
+
+    pip install pytest
+    pip install -e .  # editable install of CFFI for local development
+    pytest src/c/ testing/

+
+/* We try to define Py_LIMITED_API before including Python.h.
+
+   Mess: we can only define it if Py_DEBUG, Py_TRACE_REFS and
+   Py_REF_DEBUG are not defined.  This is a best-effort approximation:
+   we can learn about Py_DEBUG from pyconfig.h, but it is unclear if
+   the same works for the other two macros.  Py_DEBUG implies them,
+   but not the other way around.
+
+   The implementation is messy (issue #350): on Windows, with _MSC_VER,
+   we have to define Py_LIMITED_API even before including pyconfig.h.
+   In that case, we guess what pyconfig.h will do to the macros above,
+   and check our guess after the #include.
+
+   Note that on Windows, with CPython 3.x, you need >= 3.5 and virtualenv
+   version >= 16.0.0.  With older versions of either, you don't get a
+   copy of PYTHON3.DLL in the virtualenv.  We can't check the version of
+   CPython *before* we even include pyconfig.h.  ffi.set_source() puts
+   a ``#define _CFFI_NO_LIMITED_API'' at the start of this file if it is
+   running on Windows < 3.5, as an attempt at fixing it, but that's
+   arguably wrong because it may not be the target version of Python.
+   Still better than nothing I guess.  As another workaround, you can
+   remove the definition of Py_LIMITED_API here.
+
+   See also 'py_limited_api' in cffi/setuptools_ext.py.

+       completely concurrently from unrelated threads.  It assumes
+       that we don't hold the GIL before (if it exists), and we don't
+       hold it afterwards.
+
+       (What it really does used to be completely different in Python 2
+       and Python 3, with the Python 2 solution avoiding the spin-lock
+       around the Py_InitializeEx() call.  However, after recent changes
+       to CPython 2.7 (issue #358) it no longer works.  So we use the
+       Python 3 solution everywhere.)
+
+       This initializes Python by calling Py_InitializeEx().
+       Important: this must not be called concurrently at all.
+       So we use a global variable as a simple spin lock.  This global
+       variable must be from 'libpythonX.Y.so', not from this
+       cffi-based extension module, because it must be shared from
+       different cffi-based extension modules.
+
+       In Python < 3.8, we choose
+       _PyParser_TokenNames[0] as a completely arbitrary pointer value
+       that is never written to.  The default is to point to the
+       string "ENDMARKER".  We change it temporarily to point to the
+       next character in that string.  (Yes, I know it's REALLY
+       obscure.)
+
+       In Python >= 3.8, this string array is no longer writable, so
+       instead we pick PyCapsuleType.tp_version_tag.  We can't change
+       Python < 3.8 because someone might use a mixture of cffi
+       embedded modules, some of which were compiled before this file
+       changed.
+
+       In Python >= 3.12, this stopped working because that particular
+       tp_version_tag gets modified during interpreter startup.  It's
+       arguably a bad idea before 3.12 too, but again we can't change
+       that because someone might use a mixture of cffi embedded
+       modules, and no-one reported a bug so far.  In Python >= 3.12
+       we go instead for PyCapsuleType.tp_as_buffer, which is supposed
+       to always be NULL.  We write to it temporarily a pointer to
+       a struct full of NULLs, which is semantically the same.

+         PyEval_InitThreads() (possibly with Py_InitializeEx() first).
+
+       * then we use a (local) custom lock to make sure that a call to this
+         cffi-based extension will wait if another call to the *same*
+         extension is running the initialization in another thread.
+         It is reentrant, so that a recursive call will not block, but
+         only one from a different thread.
+
+       * then we grab the GIL and (Python 2) we call Py_InitializeEx().
+         At this point, concurrent calls to Py_InitializeEx() are not
+         possible: we have the GIL.
+
+       * do the rest of the specific initialization, which may
+         temporarily release the GIL but not the custom lock.

+[^1]: They are clearly using specific code for a specific encoding even if covering most of used one.
+[^2]: Chardet 7.0+ was relicensed from LGPL-2.1 to MIT following an AI-assisted rewrite. This relicensing is disputed on two independent grounds: **(a)** the original author [contests](https://github.com/chardet/chardet/issues/327) that the maintainer had the right to relicense, arguing the rewrite is a derivative work of the LGPL-licensed codebase since it was not a clean room implementation; **(b)** the copyright claim itself is [questionable](https://github.com/chardet/chardet/issues/334) given the code was primarily generated by an LLM, and AI-generated output may not be copyrightable under most jurisdictions. Either issue alone could undermine the MIT license. Beyond licensing, the rewrite raises questions about responsible use of AI in open source: key architectural ideas pioneered by charset-normalizer - notably decode-first validity filtering (our foundational approach since v1) and encoding pairwise similarity with the same algorithm and threshold — surfaced in chardet 7 without acknowledgment. The project also imported test files from charset-normalizer to train and benchmark against it, then claimed superior accuracy on those very files. Charset-normalizer has always been MIT-licensed, encoding-agnostic by design, and built on a verifiable human-authored history.

+## ⚡ Performance
+
+This package offer better performances (99th, and 95th) against Chardet. Here are some numbers.
+

+
+_updated as of March 2026 using CPython 3.12, Charset-Normalizer 3.4.6, and Chardet 7.1.0_
+
+~Chardet's performance on larger file (1MB+) are very poor. Expect huge difference on large payload.~ No longer the case since Chardet 7.0+
+
+> Stats are generated using 400+ files using default parameters. More details on used files, see GHA workflows.
+> And yes, these results might change at any time. The dataset can be updated to include more files.
+> The actual delays heavily depends on your CPU capabilities. The factors should remain the same.
+> Chardet claims on his documentation to have a greater accuracy than us based on the dataset they trained Chardet on(...)
+> Well, it's normal, the opposite would have been worrying. Whereas charset-normalizer don't train on anything, our solution
+> is based on a completely different algorithm, still heuristic through, it does not need weights across every encoding tables.
+
+## ✨ Installation
+
+Using pip:
+
+```sh
+pip install charset-normalizer -U
+```
+
+## 🚀 Basic Usage
+
+### CLI
+This package comes with a CLI.
+
+```
+usage: normalizer [-h] [-v] [-a] [-n] [-m] [-r] [-f] [-t THRESHOLD]
+                  file [file ...]
+
+The Real First Universal Charset Detector. Discover originating encoding used
+on text file. Normalize text to unicode.
+
+positional arguments:
+  files                 File(s) to be analysed
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -v, --verbose         Display complementary information about file if any.
+                        Stdout will contain logs about the detection process.
+  -a, --with-alternative
+                        Output complementary possibilities if any. Top-level
+                        JSON WILL be a list.
+  -n, --normalize       Permit to normalize input file. If not set, program
+                        does not write anything.
+  -m, --minimal         Only output the charset detected to STDOUT. Disabling
+                        JSON output.
+  -r, --replace         Replace file when trying to normalize it instead of
+                        creating a new one.
+  -f, --force           Replace file without asking if you are sure, use this
+                        flag with caution.
+  -t THRESHOLD, --threshold THRESHOLD
+                        Define a custom maximum amount of chaos allowed in
+                        decoded content. 0. <= chaos <= 1.
+  --version             Show version information and exit.
+```
+
+```bash
+normalizer ./data/sample.1.fr.srt
+```
+
+or
+
+```bash
+python -m charset_normalizer ./data/sample.1.fr.srt
+```
+
+🎉 Since version 1.4.0 the CLI produce easily usable stdout result in JSON format.
+
+```json
+{
+    "path": "/home/default/projects/charset_normalizer/data/sample.1.fr.srt",
+    "encoding": "cp1252",
+    "encoding_aliases": [
+        "1252",
+        "windows_1252"
+    ],
+    "alternative_encodings": [
+        "cp1254",
+        "cp1256",
+        "cp1258",
+        "iso8859_14",
+        "iso8859_15",
+        "iso8859_16",
+        "iso8859_3",
+        "iso8859_9",
+        "latin_1",
+        "mbcs"
+    ],
+    "language": "French",
+    "alphabets": [
+        "Basic Latin",
+        "Latin-1 Supplement"
+    ],
+    "has_sig_or_bom": false,
+    "chaos": 0.149,
+    "coherence": 97.152,
+    "unicode_path": null,
+    "is_preferred": true
+}
+```
+
+### Python
+*Just print out normalized text*
+```python
+from charset_normalizer import from_path
+
+results = from_path('./my_subtitle.srt')
+
+print(str(results.best()))
+```
+
+*Upgrade your code without effort*
+```python
+from charset_normalizer import detect
+```
+
+The above code will behave the same as **chardet**. We ensure that we offer the best (reasonable) BC result possible.
+
+See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/)
+
+## 😇 Why
+
+When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a
+reliable alternative using a completely different method. Also! I never back down on a good challenge!
+
+I **don't care** about the **originating charset** encoding, because **two different tables** can
+produce **two identical rendered string.**
+What I want is to get readable text, the best I can.
+
+In a way, **I'm brute forcing text decoding.** How cool is that ? 😎
+
+Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode.
+
+## 🍰 How
+
+  - Discard all charset encoding table that could not fit the binary content.
+  - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding.
+  - Extract matches with the lowest mess detected.
+  - Additionally, we measure coherence / probe for a language.
+
+**Wait a minute**, what is noise/mess and coherence according to **YOU ?**
+
+*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then
+**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text).
+ I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to
+ improve or rewrite it.
+
+*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought
+that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design.
+
+## ⚡ Known limitations
+
+  - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters))
+  - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content.
+
+## ⚠️ About Python EOLs
+
+**If you are running:**
+
+- Python >=2.7,<3.5: Unsupported
+- Python 3.5: charset-normalizer < 2.1
+- Python 3.6: charset-normalizer < 3.1
+
+Upgrade your Python interpreter as soon as possible.

+Charset-Normalizer
+~~~~~~~~~~~~~~
+The Real First Universal Charset Detector.
+A library that helps you read text from an unknown charset encoding.
+Motivated by chardet, This package is trying to resolve the issue by taking a new approach.
+All IANA character set names for which the Python core library provides codecs are supported.
+
+Basic usage:
+   >>> from charset_normalizer import from_bytes
+   >>> results = from_bytes('Bсеки човек има право на образование. Oбразованието!'.encode('utf_8'))
+   >>> best_guess = results.best()
+   >>> str(best_guess)
+   'Bсеки човек има право на образование. Oбразованието!'
+
+Others methods and usages are available - see the full documentation
+at <https://github.com/Ousret/charset_normalizer>.

+# Click
+
+Click is a Python package for creating beautiful command line interfaces
+in a composable way with as little code as necessary. It's the "Command
+Line Interface Creation Kit". It's highly configurable but comes with
+sensible defaults out of the box.
+
+It aims to make the process of writing command line tools quick and fun
+while also preventing any frustration caused by the inability to
+implement an intended CLI API.
+
+Click in three points:
+
+-   Arbitrary nesting of commands
+-   Automatic help page generation
+-   Supports lazy loading of subcommands at runtime
+
+
+## A Simple Example
+
+```python
+import click
+
+@click.command()
+@click.option("--count", default=1, help="Number of greetings.")
+@click.option("--name", prompt="Your name", help="The person to greet.")
+def hello(count, name):
+    """Simple program that greets NAME for a total of COUNT times."""
+    for _ in range(count):
+        click.echo(f"Hello, {name}!")
+
+if __name__ == '__main__':
+    hello()
+```
+
+```
+$ python hello.py --count=3
+Your name: Click
+Hello, Click!
+Hello, Click!
+Hello, Click!
+```

+

+                      is the most descriptive name for the script or
+                      command.  For the toplevel script it is usually

+                               variables which are always read.
+    :param default_map: a dictionary (like object) with default values
+                        for parameters.
+    :param terminal_width: the width of the terminal.  The default is
+                           inherit from parent context.  If no context

+                             at the end will not raise an error and will be
+                             kept on the context.  The default is to inherit

+                              the default help parameter is named.  The
+                              default is ``['--help']``.

+                                 etc.).  This for instance can be used to
+                                 implement case insensitive behavior.
+    :param color: controls if the terminal supports ANSI colors or not.  The
+                  default is autodetection.  This is only needed if ANSI
+                  codes are used in texts that Click prints which is by

+        specific command.

+

+

+                        argument.  This is a list of flags or argument
+                        names.
+    :param type: the type that should be used.  Either a :class:`ParamType`
+                 or a Python type.  The latter is converted into the former
+                 automatically if supported.

+                    without any arguments.
+    :param callback: A function to further process or validate the value
+        after type conversion. It is called as ``f(ctx, param, value)``
+        and must return the value. It is called for all sources,
+        including prompts.
+    :param nargs: the number of arguments to match.  If not ``1`` the return
+                  value is a tuple instead of single value.  The default for
+                  nargs is ``1`` (except if the type is a tuple, then it's
+                  the arity of the tuple). If ``nargs=-1``, all remaining
+                  parameters are collected.
+    :param metavar: how the value is represented in the help page.
+    :param expose_value: if this is `True` then the value is passed onwards
+                         to the command callback and stored on the context,
+                         otherwise it's skipped.
+    :param is_eager: eager values are processed before non eager ones.  This
+                     should not be set for arguments or it will inverse the
+                     order of processing.
+    :param envvar: environment variable(s) that are used to provide a default value for
+        this parameter. This can be a string or a sequence of strings. If a sequence is
+        given, only the first non-empty environment variable is used for the parameter.
+    :param shell_complete: A function that returns custom shell
+        completions. Used instead of the param's type completion if
+        given. Takes ``ctx, param, incomplete`` and must return a list
+        of :class:`~click.shell_completion.CompletionItem` or a list of
+        strings.
+    :param deprecated: If ``True`` or non-empty string, issues a message
+                        indicating that the argument is deprecated and highlights
+                        its deprecation in --help. The message can be customized
+                        by using a string as the value. A deprecated parameter
+                        cannot be required, a ValueError will be raised otherwise.

+
+    .. versionchanged:: 8.0
+        ``process_value`` validates required parameters and bounded
+        ``nargs``, and invokes the parameter callback before returning
+        the value. This allows the callback to validate prompts.
+        ``full_process_value`` is removed.
+
+    .. versionchanged:: 8.0
+        ``autocompletion`` is renamed to ``shell_complete`` and has new

+        be removed in 8.1, until then it will be wrapped to match the
+        new requirements.
+
+    .. versionchanged:: 8.0
+        For ``multiple=True, nargs>1``, the default must be a list of
+        tuples.
+
+    .. versionchanged:: 8.0
+        Setting a default is no longer required for ``nargs>1``, it will
+        default to ``None``. ``multiple=True`` or ``nargs=-1`` will
+        default to ``()``.
+
+    .. versionchanged:: 7.1
+        Empty environment variables are ignored rather than taking the
+        empty string value. This makes it possible for scripts to clear
+        variables if they can't unset them.
+
+    .. versionchanged:: 2.0
+        Changed signature for parameter callback to also be passed the
+        parameter. The old callback format will still work, but it will

+"""
+This module started out as largely a copy paste from the stdlib's
+optparse module with the features removed that we do not need from
+optparse because we implement them in Click on a higher level (for
+instance type handling, help formatting and a lot more).
+
+The plan is to remove more and more from here over time.
+
+The reason this is a different module and not optparse from the stdlib
+is that there are differences in 2.x and 3.x about the error messages
+generated and optparse in the stdlib uses gettext for no good reason
+and might cause us issues.
+
+Click uses parts of optparse written by Gregory P. Ward and maintained
+by the Python Software Foundation. This is limited to code in parser.py.

+    """This function creates an iterable context manager that can be used
+    to iterate over something while showing a progress bar.  It will
+    either iterate over the `iterable` or `length` items (that are counted
+    up).  While iteration happens, this function will print a rendered
+    progress bar to the given `file` (defaults to stdout) and will attempt
+    to calculate remaining time and more.  By default, this progress bar
+    will not be rendered if the file is not a terminal.
+
+    The context manager creates the progress bar.  When the context
+    manager is entered the progress bar is already created.  With every
+    iteration over the progress bar, the iterable passed to the bar is
+    advanced and the bar is updated.  When the context manager exits,
+    a newline is printed and the progress bar is finalized on screen.
+
+    Note: The progress bar is currently designed for use cases where the
+    total progress can be expected to take at least several seconds.
+    Because of this, the ProgressBar class object won't display
+    progress that is considered too fast, and progress where the time
+    between steps is less than a second.
+
+    No printing must happen or the progress bar will be unintentionally
+    destroyed.
+
+    Example usage::
+
+        with progressbar(items) as bar:
+            for item in bar:
+                do_something_with(item)
+
+    Alternatively, if no iterable is specified, one can manually update the
+    progress bar through the `update()` method instead of directly
+    iterating over the progress bar.  The update method accepts the number
+    of steps to increment the bar with::
+
+        with progressbar(length=chunks.total_bytes) as bar:
+            for chunk in chunks:
+                process_chunk(chunk)
+                bar.update(chunks.bytes)
+
+    The ``update()`` method also takes an optional value specifying the
+    ``current_item`` at the new position. This is useful when used
+    together with ``item_show_func`` to customize the output for each
+    manual step::
+
+        with click.progressbar(
+            length=total_size,
+            label='Unzipping archive',
+            item_show_func=lambda a: a.filename
+        ) as bar:
+            for archive in zip_file:
+                archive.extract()
+                bar.update(archive.size, archive)
+
+    :param iterable: an iterable to iterate over.  If not provided the length
+                     is required.
+    :param length: the number of items to iterate over.  By default the
+                   progressbar will attempt to ask the iterator about its
+                   length, which might or might not work.  If an iterable is
+                   also provided this parameter can be used to override the
+                   length.  If an iterable is not provided the progress bar
+                   will iterate over a range of that length.
+    :param label: the label to show next to the progress bar.
+    :param hidden: hide the progressbar. Defaults to ``False``. When no tty is
+        detected, it will only print the progressbar label. Setting this to
+        ``False`` also disables that.
+    :param show_eta: enables or disables the estimated time display.  This is
+                     automatically disabled if the length cannot be
+                     determined.
+    :param show_percent: enables or disables the percentage display.  The
+                         default is `True` if the iterable has a length or
+                         `False` if not.
+    :param show_pos: enables or disables the absolute position display.  The
+                     default is `False`.
+    :param item_show_func: A function called with the current item which
+        can return a string to show next to the progress bar. If the
+        function returns ``None`` nothing is shown. The current item can
+        be ``None``, such as when entering and exiting the bar.
+    :param fill_char: the character to use to show the filled part of the
+                      progress bar.
+    :param empty_char: the character to use to show the non-filled part of
+                       the progress bar.
+    :param bar_template: the format string to use as template for the bar.
+                         The parameters in it are ``label`` for the label,
+                         ``bar`` for the progress bar and ``info`` for the
+                         info section.
+    :param info_sep: the separator between multiple info items (eta etc.)
+    :param width: the width of the progress bar in characters, 0 means full
+                  terminal width
+    :param file: The file to write to. If this is not a terminal then
+        only the label is printed.
+    :param color: controls if the terminal supports ANSI colors or not.  The
+                  default is autodetection.  This is only needed if ANSI
+                  codes are included anywhere in the progress bar output
+                  which is not the case by default.
+    :param update_min_steps: Render only when this many updates have
+        completed. This allows tuning for very fast iterators.

+
+``cryptography`` is a package which provides cryptographic recipes and
+primitives to Python developers. Our goal is for it to be your "cryptographic
+standard library". It supports Python 3.8+ and PyPy3 7.3.11+.
+
+``cryptography`` includes both high level recipes and low level interfaces to
+common cryptographic algorithms such as symmetric ciphers, message digests, and
+key derivation functions. For example, to encrypt something with
+``cryptography``'s high level symmetric encryption recipe:
+
+.. code-block:: pycon
+
+    >>> from cryptography.fernet import Fernet
+    >>> # Put this somewhere safe!
+    >>> key = Fernet.generate_key()
+    >>> f = Fernet(key)
+    >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
+    >>> token
+    b'...'
+    >>> f.decrypt(token)
+    b'A really secret message. Not for prying eyes.'
+
+You can find more information in the `documentation`_.
+
+You can install ``cryptography`` with:
+
+.. code-block:: console
+
+    $ pip install cryptography
+
+For full details see `the installation documentation`_.
+
+Discussion
+~~~~~~~~~~
+
+If you run into bugs, you can file them in our `issue tracker`_.
+
+We maintain a `cryptography-dev`_ mailing list for development discussion.
+
+You can also join ``#pyca`` on ``irc.libera.chat`` to ask questions or get
+involved.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+              are also functionally equivalent. That is to say, failing to
+              provide a subnetmask will create an object with a mask of /32.
+
+              If the mask (portion after the / in the argument) is given in
+              dotted quad form, it is treated as a netmask if it starts with a
+              non-zero field (e.g. /255.0.0.0 == /8) and as a hostmask if it
+              starts with a zero field (e.g. 0.255.255.255 == /8), with the
+              single exception of an all-zero mask which is treated as a
+              netmask == /0. If no mask is given, a default of /32 is used.
+
+              Additionally, an integer can be passed, so

+Python shell for SymPy.
+
+This is just a normal Python shell (IPython shell if you have the
+IPython package installed), that executes the following commands for
+the user:
+
+    >>> from __future__ import division
+    >>> from sympy import *
+    >>> x, y, z, t = symbols('x y z t')
+    >>> k, m, n = symbols('k m n', integer=True)
+    >>> f, g, h = symbols('f g h', cls=Function)
+    >>> init_printing()
+
+So starting 'isympy' is equivalent to starting Python (or IPython) and
+executing the above commands by hand.  It is intended for easy and quick
+experimentation with SymPy.  isympy is a good way to use SymPy as an
+interactive calculator. If you have IPython and Matplotlib installed, then
+interactive plotting is enabled by default.
+
+COMMAND LINE OPTIONS
+--------------------
+
+-c CONSOLE, --console=CONSOLE
+
+     Use the specified shell (Python or IPython) shell as the console
+     backend instead of the default one (IPython if present, Python
+     otherwise), e.g.:
+
+        $isympy -c python
+
+    CONSOLE must be one of 'ipython' or 'python'
+
+-p PRETTY, --pretty PRETTY
+
+    Setup pretty-printing in SymPy. When pretty-printing is enabled,
+    expressions can be printed with Unicode or ASCII. The default is
+    to use pretty-printing (with Unicode if the terminal supports it).
+    When this option is 'no', expressions will not be pretty-printed
+    and ASCII will be used:
+
+        $isympy -p no
+
+    PRETTY must be one of 'unicode', 'ascii', or 'no'
+
+-t TYPES, --types=TYPES
+
+    Setup the ground types for the polys.  By default, gmpy ground types
+    are used if gmpy2 or gmpy is installed, otherwise it falls back to python
+    ground types, which are a little bit slower.  You can manually
+    choose python ground types even if gmpy is installed (e.g., for
+    testing purposes):
+
+        $isympy -t python
+
+    TYPES must be one of 'gmpy', 'gmpy1' or 'python'
+
+    Note that the ground type gmpy1 is primarily intended for testing; it
+    forces the use of gmpy version 1 even if gmpy2 is available.
+
+    This is the same as setting the environment variable
+    SYMPY_GROUND_TYPES to the given ground type (e.g.,
+    SYMPY_GROUND_TYPES='gmpy')
+
+    The ground types can be determined interactively from the variable
+    sympy.polys.domains.GROUND_TYPES.
+
+-o ORDER, --order ORDER
+
+    Setup the ordering of terms for printing.  The default is lex, which
+    orders terms lexicographically (e.g., x**2 + x + 1). You can choose
+    other orderings, such as rev-lex, which will use reverse
+    lexicographic ordering (e.g., 1 + x + x**2):
+
+        $isympy -o rev-lex
+
+    ORDER must be one of 'lex', 'rev-lex', 'grlex', 'rev-grlex',
+    'grevlex', 'rev-grevlex', 'old', or 'none'.
+
+    Note that for very large expressions, ORDER='none' may speed up
+    printing considerably but the terms will have no canonical order.
+
+-q, --quiet
+
+    Print only Python's and SymPy's versions to stdout at startup.
+
+-d, --doctest
+
+    Use the same format that should be used for doctests.  This is
+    equivalent to -c python -p no.
+
+-C, --no-cache
+
+    Disable the caching mechanism.  Disabling the cache may slow certain
+    operations down considerably.  This is useful for testing the cache,
+    or for benchmarking, as the cache can result in deceptive timings.
+
+    This is equivalent to setting the environment variable
+    SYMPY_USE_CACHE to 'no'.
+
+-a, --auto-symbols (requires at least IPython 0.11)
+
+    Automatically create missing symbols.  Normally, typing a name of a
+    Symbol that has not been instantiated first would raise NameError,
+    but with this option enabled, any undefined name will be
+    automatically created as a Symbol.
+
+    Note that this is intended only for interactive, calculator style
+    usage. In a script that uses SymPy, Symbols should be instantiated
+    at the top, so that it's clear what they are.
+
+    This will not override any names that are already defined, which
+    includes the single character letters represented by the mnemonic
+    QCOSINE (see the "Gotchas and Pitfalls" document in the
+    documentation). You can delete existing names by executing "del
+    name".  If a name is defined, typing "'name' in dir()" will return True.
+
+    The Symbols that are created using this have default assumptions.
+    If you want to place assumptions on symbols, you should create them
+    using symbols() or var().
+
+    Finally, this only works in the top level namespace. So, for
+    example, if you define a function in isympy with an undefined
+    Symbol, it will not work.
+
+    See also the -i and -I options.
+
+-i, --int-to-Integer (requires at least IPython 0.11)
+
+    Automatically wrap int literals with Integer.  This makes it so that
+    things like 1/2 will come out as Rational(1, 2), rather than 0.5.  This
+    works by preprocessing the source and wrapping all int literals with
+    Integer.  Note that this will not change the behavior of int literals
+    assigned to variables, and it also won't change the behavior of functions
+    that return int literals.
+
+    If you want an int, you can wrap the literal in int(), e.g. int(3)/int(2)
+    gives 1.5 (with division imported from __future__).
+
+-I, --interactive (requires at least IPython 0.11)
+
+    This is equivalent to --auto-symbols --int-to-Integer.  Future options
+    designed for ease of interactive use may be added to this.
+
+-D, --debug
+
+    Enable debugging output.  This is the same as setting the
+    environment variable SYMPY_DEBUG to 'True'.  The debug status is set
+    in the variable SYMPY_DEBUG within isympy.
+
+-- IPython options
+
+    Additionally you can pass command line options directly to the IPython
+    interpreter (the standard Python shell is not supported).  However you
+    need to add the '--' separator between two types of options, e.g the
+    startup banner option and the colors option. You need to enter the
+    options as required by the version of IPython that you are using, too:
+
+    in IPython 0.11,
+
+        $isympy -q -- --colors=NoColor
+
+    or older versions of IPython,
+
+        $isympy -q -- -colors NoColor
+
+See also isympy --help.

+Use W&B to build better models faster. Track and visualize all the pieces of your machine learning pipeline, from datasets to production machine learning models. Get started with W&B today, [sign up for a W&B account](https://wandb.com?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=readme)!
+
+<br>
+
+Building an LLM app? Track, debug, evaluate, and monitor LLM apps with [Weave](https://wandb.github.io/weave?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=readme), our new suite of tools for GenAI.
+
+&nbsp;
+
+# Documentation
+
+See the [W&B Developer Guide](https://docs.wandb.ai/?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=documentation) and [API Reference Guide](https://docs.wandb.ai/training/api-reference#api-overview?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=documentation) for a full technical description of the W&B platform.
+
+&nbsp;
+
+# Quickstart
+
+Install W&B to track, visualize, and manage machine learning experiments of any size.
+
+## Install the wandb library
+
+```shell
+pip install wandb
+```
+
+## Sign up and create an API key
+
+Sign up for a [W&B account](https://wandb.ai/login?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=quickstart). Optionally, use the `wandb login` CLI to configure an API key on your machine. You can skip this step -- W&B will prompt you for an API key the first time you use it.
+
+## Create a machine learning training experiment
+
+In your Python script or notebook, initialize a W&B run with `wandb.init()`.
+Specify hyperparameters and log metrics and other information to W&B.
+
+```python
+import wandb
+
+# Project that the run is recorded to
+project = "my-awesome-project"
+
+# Dictionary with hyperparameters
+config = {"epochs" : 1337, "lr" : 3e-4}
+
+# The `with` syntax marks the run as finished upon exiting the `with` block,
+# and it marks the run "failed" if there's an exception.
+#
+# In a notebook, it may be more convenient to write `run = wandb.init()`
+# and manually call `run.finish()` instead of using a `with` block.
+with wandb.init(project=project, config=config) as run:
+    # Training code here
+
+    # Log values to W&B with run.log()
+    run.log({"accuracy": 0.9, "loss": 0.1})
+```
+
+Visit [wandb.ai/home](https://wandb.ai/home) to view recorded metrics such as accuracy and loss and how they changed during each training step. Each run object appears in the Runs column with generated names.
+
+&nbsp;
+
+# Integrations
+
+W&B [integrates](https://docs.wandb.ai/models/integrations) with popular ML frameworks and libraries making it fast and easy to set up experiment tracking and data versioning inside existing projects.
+
+For developers adding W&B to a new framework, follow the [W&B Developer Guide](https://docs.wandb.ai/models/integrations/add-wandb-to-any-library).
+
+&nbsp;
+
+# W&B Hosting Options
+
+Weights & Biases is available in the cloud or installed on your private infrastructure. Set up a W&B Server in a production environment in one of three ways:
+
+1. [Multi-tenant Cloud](https://docs.wandb.ai/platform/hosting/hosting-options/multi_tenant_cloud?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=hosting): Fully managed platform deployed in W&B’s Google Cloud Platform (GCP) account in GCP’s North America regions.
+2. [Dedicated Cloud](https://docs.wandb.ai/platform/hosting/hosting-options/dedicated_cloud?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=hosting): Single-tenant, fully managed platform deployed in W&B’s AWS, GCP, or Azure cloud accounts. Each Dedicated Cloud instance has its own isolated network, compute and storage from other W&B Dedicated Cloud instances.
+3. [Self-Managed](https://docs.wandb.ai/platform/hosting/hosting-options/self-managed?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=hosting): Deploy W&B Server on your AWS, GCP, or Azure cloud account or within your on-premises infrastructure.
+
+See the [Hosting documentation](https://docs.wandb.ai/guides/hosting?utm_source=github&utm_medium=code&utm_campaign=wandb&utm_content=hosting) in the W&B Developer Guide for more information.
+
+&nbsp;
+
+# Python Version Support
+
+We are committed to supporting our minimum required Python version for _at least_ six months after its official end-of-life (EOL) date, as defined by the Python Software Foundation. You can find a list of Python EOL dates [here](https://devguide.python.org/versions/).
+
+When we discontinue support for a Python version, we will increment the library’s minor version number to reflect this change.
+
+&nbsp;
+
+# Contribution guidelines
+
+Weights & Biases ❤️ open source, and we welcome contributions from the community! See the [Contribution guide](https://github.com/wandb/wandb/blob/main/CONTRIBUTING.md) for more information on the development workflow and the internals of the wandb library. For wandb bugs and feature requests, visit [GitHub Issues](https://github.com/wandb/wandb/issues) or contact support@wandb.com.

+
+        TypedDict creates a dictionary type such that a type checker will expect all
+        instances to have a certain set of keys, where each key is
+        associated with a value of a consistent type. This expectation
+        is not checked at runtime.
+
+        Usage::
+
+            class Point2D(TypedDict):
+                x: int
+                y: int
+                label: str
+
+            a: Point2D = {'x': 1, 'y': 2, 'label': 'good'}  # OK
+            b: Point2D = {'z': 3, 'label': 'bad'}           # Fails type check
+
+            assert Point2D(x=1, y=2, label='first') == dict(x=1, y=2, label='first')
+
+        The type info can be accessed via the Point2D.__annotations__ dict, and
+        the Point2D.__required_keys__ and Point2D.__optional_keys__ frozensets.
+        TypedDict supports an additional equivalent form::
+
+            Point2D = TypedDict('Point2D', {'x': int, 'y': int, 'label': str})
+
+        By default, all keys must be present in a TypedDict. It is possible
+        to override this by specifying totality::
+
+            class Point2D(TypedDict, total=False):
+                x: int
+                y: int
+
+        This means that a Point2D TypedDict can have any of the keys omitted. A type
+        checker is only expected to support a literal False or True as the value of
+        the total argument. True is the default, and makes all items defined in the
+        class body be required.
+
+        The Required and NotRequired special forms can also be used to mark
+        individual keys as being required or not required::
+
+            class Point2D(TypedDict):
+                x: int  # the "x" key must always be present (Required is the default)
+                y: NotRequired[int]  # the "y" key can be omitted
+
+        See PEP 655 for more details on Required and NotRequired.

+        Usage::
+
+           P = ParamSpec('P')
+
+        Parameter specification variables exist primarily for the benefit of static
+        type checkers.  They are used to forward the parameter types of one
+        callable to another callable, a pattern commonly found in higher order
+        functions and decorators.  They are only valid when used in ``Concatenate``,
+        or s the first argument to ``Callable``. In Python 3.10 and higher,
+        they are also supported in user-defined Generics at runtime.
+        See class Generic for more information on generic types.  An
+        example for annotating a decorator::
+
+           T = TypeVar('T')
+           P = ParamSpec('P')
+
+           def add_logging(f: Callable[P, T]) -> Callable[P, T]:
+               '''A type-safe decorator to add logging to a function.'''
+               def inner(*args: P.args, **kwargs: P.kwargs) -> T:
+                   logging.info(f'{f.__name__} was called')
+                   return f(*args, **kwargs)

+           def add_two(x: float, y: float) -> float:
+               '''Add two numbers together.'''

+
+        Parameter specification variables defined with covariant=True or
+        contravariant=True can be used to declare covariant or contravariant
+        generic types.  These keyword arguments are valid, but their actual semantics
+        are yet to be decided.  See PEP 612 for details.
+
+        Parameter specification variables can be introspected. e.g.:
+
+           P.__name__ == 'T'
+           P.__bound__ == None
+           P.__covariant__ == False
+           P.__contravariant__ == False

+
+        Usage::
+
+            Ts = TypeVarTuple('Ts')
+
+        In the same way that a normal type variable is a stand-in for a single
+        type such as ``int``, a type variable *tuple* is a stand-in for a *tuple*
+        type such as ``Tuple[int, str]``.
+
+        Type variable tuples can be used in ``Generic`` declarations.
+        Consider the following example::
+
+            class Array(Generic[*Ts]): ...
+
+        The ``Ts`` type variable tuple here behaves like ``tuple[T1, T2]``,
+        where ``T1`` and ``T2`` are type variables. To use these type variables
+        as type parameters of ``Array``, we must *unpack* the type variable tuple using
+        the star operator: ``*Ts``. The signature of ``Array`` then behaves
+        as if we had simply written ``class Array(Generic[T1, T2]): ...``.
+        In contrast to ``Generic[T1, T2]``, however, ``Generic[*Shape]`` allows
+        us to parameterise the class with an *arbitrary* number of type parameters.
+
+        Type variable tuples can be used anywhere a normal ``TypeVar`` can.
+        This includes class definitions, as shown above, as well as function
+        signatures and variable annotations::
+
+            class Array(Generic[*Ts]):
+
+                def __init__(self, shape: Tuple[*Ts]):

+        it's called; calling it twice on the same object will return two
+        different but equivalent dicts.
+
+        This is a backport of `inspect.get_annotations`, which has been
+        in the standard library since Python 3.10. See the standard library
+        documentation for more:
+
+            https://docs.python.org/3/library/inspect.html#inspect.get_annotations
+
+        This backport adds the *format* argument introduced by PEP 649. The
+        three formats supported are:
+        * VALUE: the annotations are returned as-is. This is the default and
+          it is compatible with the behavior on previous Python versions.
+        * FORWARDREF: return annotations as-is if possible, but replace any
+          undefined names with ForwardRef objects. The implementation proposed by
+          PEP 649 relies on language changes that cannot be backported; the
+          typing-extensions implementation simply returns the same result as VALUE.
+        * STRING: return annotations as strings, in a format close to the original
+          source. Again, this behavior cannot be replicated directly in a backport.
+          As an approximation, typing-extensions retrieves the annotations under
+          VALUE semantics and then stringifies them.
+
+        The purpose of this backport is to allow users who would like to use
+        FORWARDREF or STRING semantics once PEP 649 is implemented, but who also
+        want to support earlier Python versions, to simply write:
