Suite](https://github.com/encode/httpcore/workflows/Test%20Suite/badge.svg)](https://github.com/encode/httpcore/actions) +[![Package version](https://badge.fury.io/py/httpcore.svg)](https://pypi.org/project/httpcore/) + +> *Do one thing, and do it well.* + +The HTTP Core package provides a minimal low-level HTTP client, which does +one thing only. Sending HTTP requests. + +It does not provide any high level model abstractions over the API, +does not handle redirects, multipart uploads, building authentication headers, +transparent HTTP caching, URL parsing, session cookie handling, +content or charset decoding, handling JSON, environment based configuration +defaults, or any of that Jazz. + +Some things HTTP Core does do: + +* Sending HTTP requests. +* Thread-safe / task-safe connection pooling. +* HTTP(S) proxy & SOCKS proxy support. +* Supports HTTP/1.1 and HTTP/2. +* Provides both sync and async interfaces. +* Async backend support for `asyncio` and `trio`. + +## Requirements + +Python 3.8+ + +## Installation + +For HTTP/1.1 only support, install with: + +```shell +$ pip install httpcore +``` + +There are also a number of optional extras available... + +```shell +$ pip install httpcore['asyncio,trio,http2,socks'] +``` + +## Sending requests + +Send an HTTP request: + +```python +import httpcore + +response = httpcore.request("GET", "https://www.example.com/") + +print(response) +# +print(response.status) +# 200 +print(response.headers) +# [(b'Accept-Ranges', b'bytes'), (b'Age', b'557328'), (b'Cache-Control', b'max-age=604800'), ...] +print(response.content) +# b'\n\n\nExample Domain\n\n\n ...' +``` + +The top-level `httpcore.request()` function is provided for convenience. In practice whenever you're working with `httpcore` you'll want to use the connection pooling functionality that it provides. + +```python +import httpcore + +http = httpcore.ConnectionPool() +response = http.request("GET", "https://www.example.com/") +``` + +Once you're ready to get going, [head over to the documentation](https://www.encode.io/httpcore/). + +## Motivation + +You *probably* don't want to be using HTTP Core directly. It might make sense if +you're writing something like a proxy service in Python, and you just want +something at the lowest possible level, but more typically you'll want to use +a higher level client library, such as `httpx`. + +The motivation for `httpcore` is: + +* To provide a reusable low-level client library, that other packages can then build on top of. +* To provide a *really clear interface split* between the networking code and client logic, + so that each is easier to understand and reason about in isolation. + +## Dependencies + +The `httpcore` package has the following dependencies... + +* `h11` +* `certifi` + +And the following optional extras... + +* `anyio` - Required by `pip install httpcore['asyncio']`. +* `trio` - Required by `pip install httpcore['trio']`. +* `h2` - Required by `pip install httpcore['http2']`. +* `socksio` - Required by `pip install httpcore['socks']`. + +## Versioning + +We use [SEMVER for our versioning policy](https://semver.org/). + +For changes between package versions please see our [project changelog](CHANGELOG.md). + +We recommend pinning your requirements either the most current major version, or a more specific version range: + +```python +pip install 'httpcore==1.*' +``` +# Changelog + +All notable changes to this project will be documented in this file. + +The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). + +## Version 1.0.9 (April 24th, 2025) + +- Resolve https://github.com/advisories/GHSA-vqfr-h8mv-ghfj with h11 dependency update.

This extension is needed for the HTTPX cli, in order to... + +* Log the point at which the connection is established, and the IP/port on which it is made. +* Determine if the outgoing request should log as HTTP/1.1 or HTTP/2, rather than having to assume it's HTTP/2 if the --http2 flag was passed. (Which may not actually be true.) +* Log SSL version info / certificate info. + +Note that `curio` support is not currently available in 0.14.0. If you're using `httpcore` with `curio` please get in touch, so we can assess if we ought to prioritize it as a feature or not. + +## 0.13.7 (September 13th, 2021) + +- Fix broken error messaging when URL scheme is missing, or a non HTTP(S) scheme is used. (Pull #403) + +## 0.13.6 (June 15th, 2021) + +### Fixed + +- Close sockets when read or write timeouts occur. (Pull #365) + +## 0.13.5 (June 14th, 2021) + +### Fixed + +- Resolved niggles with AnyIO EOF behaviours. (Pull #358, #362) + +## 0.13.4 (June 9th, 2021) + +### Added + +- Improved error messaging when URL scheme is missing, or a non HTTP(S) scheme is used. (Pull #354) + +### Fixed + +- Switched to `anyio` as the default backend implementation when running with `asyncio`. Resolves some awkward [TLS timeout issues](https://github.com/encode/httpx/discussions/1511). + +## 0.13.3 (May 6th, 2021) + +### Added + +- Support HTTP/2 prior knowledge, using `httpcore.SyncConnectionPool(http1=False)`. (Pull #333) + +### Fixed + +- Handle cases where environment does not provide `select.poll` support. (Pull #331) + +## 0.13.2 (April 29th, 2021) + +### Added + +- Improve error message for specific case of `RemoteProtocolError` where server disconnects without sending a response. (Pull #313) + +## 0.13.1 (April 28th, 2021) + +### Fixed + +- More resiliant testing for closed connections. (Pull #311) +- Don't raise exceptions on ungraceful connection closes. (Pull #310) + +## 0.13.0 (April 21st, 2021) + +The 0.13 release updates the core API in order to match the HTTPX Transport API, +introduced in HTTPX 0.18 onwards. + +An example of making requests with the new interface is: + +```python +with httpcore.SyncConnectionPool() as http: + status_code, headers, stream, extensions = http.handle_request( + method=b'GET', + url=(b'https', b'example.org', 443, b'/'), + headers=[(b'host', b'example.org'), (b'user-agent', b'httpcore')] + stream=httpcore.ByteStream(b''), + extensions={} + ) + body = stream.read() + print(status_code, body) +``` + +### Changed + +- The `.request()` method is now `handle_request()`. (Pull #296) +- The `.arequest()` method is now `.handle_async_request()`. (Pull #296) +- The `headers` argument is no longer optional. (Pull #296) +- The `stream` argument is no longer optional. (Pull #296) +- The `ext` argument is now named `extensions`, and is no longer optional. (Pull #296) +- The `"reason"` extension keyword is now named `"reason_phrase"`. (Pull #296) +- The `"reason_phrase"` and `"http_version"` extensions now use byte strings for their values. (Pull #296) +- The `httpcore.PlainByteStream()` class becomes `httpcore.ByteStream()`. (Pull #296) + +### Added + +- Streams now support a `.read()` interface. (Pull #296) + +### Fixed + +- Task cancellation no longer leaks connections from the connection pool. (Pull #305) + +## 0.12.3 (December 7th, 2020) + +### Fixed + +- Abort SSL connections on close rather than waiting for remote EOF when using `asyncio`. (Pull #167) +- Fix exception raised in case of connect timeouts when using the `anyio` backend. (Pull #236) +- Fix `Host` header precedence for `:authority` in HTTP/2. (Pull #241, #243) +- Handle extra edge case when detecting for socket readability when using `asyncio`. (Pull #242, #244) +- Fix `asyncio` SSL warning when using proxy tunneling.

(Pull #221) + +### Fixed + +- Tweak detection of dropped connections, resolving an issue with open files limits on Linux. (Pull #185) +- Avoid leaking connections when establishing an HTTP tunnel to a proxy has failed. (Pull #223) +- Properly wrap OS errors when using `trio`. (Pull #225) + +## 0.12.0 (October 6th, 2020) + +### Changed + +- HTTP header casing is now preserved, rather than always sent in lowercase. (#216 and python-hyper/h11#104) + +### Added + +- Add Python 3.9 to officially supported versions. + +### Fixed + +- Gracefully handle a stdlib asyncio bug when a connection is closed while it is in a paused-for-reading state. (#201) + +## 0.11.1 (September 28nd, 2020) + +### Fixed + +- Add await to async semaphore release() coroutine (#197) +- Drop incorrect curio classifier (#192) + +## 0.11.0 (September 22nd, 2020) + +The Transport API with 0.11.0 has a couple of significant changes. + +Firstly we've moved changed the request interface in order to allow extensions, which will later enable us to support features +such as trailing headers, HTTP/2 server push, and CONNECT/Upgrade connections. + +The interface changes from: + +```python +def request(method, url, headers, stream, timeout): + return (http_version, status_code, reason, headers, stream) +``` + +To instead including an optional dictionary of extensions on the request and response: + +```python +def request(method, url, headers, stream, ext): + return (status_code, headers, stream, ext) +``` + +Having an open-ended extensions point will allow us to add later support for various optional features, that wouldn't otherwise be supported without these API changes. + +In particular: + +* Trailing headers support. +* HTTP/2 Server Push +* sendfile. +* Exposing raw connection on CONNECT, Upgrade, HTTP/2 bi-di streaming. +* Exposing debug information out of the API, including template name, template context. + +Currently extensions are limited to: + +* request: `timeout` - Optional. Timeout dictionary. +* response: `http_version` - Optional. Include the HTTP version used on the response. +* response: `reason` - Optional. Include the reason phrase used on the response. Only valid with HTTP/1.*. + +See https://github.com/encode/httpx/issues/1274#issuecomment-694884553 for the history behind this. + +Secondly, the async version of `request` is now namespaced as `arequest`. + +This allows concrete transports to support both sync and async implementations on the same class. + +### Added + +- Add curio support. (Pull #168) +- Add anyio support, with `backend="anyio"`. (Pull #169) + +### Changed + +- Update the Transport API to use 'ext' for optional extensions. (Pull #190) +- Update the Transport API to use `.request` and `.arequest` so implementations can support both sync and async. (Pull #189) + +## 0.10.2 (August 20th, 2020) + +### Added + +- Added Unix Domain Socket support. (Pull #139) + +### Fixed + +- Always include the port on proxy CONNECT requests. (Pull #154) +- Fix `max_keepalive_connections` configuration. (Pull #153) +- Fixes behaviour in HTTP/1.1 where server disconnects can be used to signal the end of the response body. (Pull #164) + +## 0.10.1 (August 7th, 2020) + +- Include `max_keepalive_connections` on `AsyncHTTPProxy`/`SyncHTTPProxy` classes. + +## 0.10.0 (August 7th, 2020) + +The most notable change in the 0.10.0 release is that HTTP/2 support is now fully optional. + +Use either `pip install httpcore` for HTTP/1.1 support only, or `pip install httpcore[http2]` for HTTP/1.1 and HTTP/2 support. + +### Added + +- HTTP/2 support becomes optional. (Pull #121, #130) +- Add `local_address=...` support. (Pull #100, #134) +- Add `PlainByteStream`, `IteratorByteStream`, `AsyncIteratorByteStream`. The `AsyncByteSteam` and `SyncByteStream` classes are now pure interface classes. (#133) +- Add `LocalProtocolError`, `RemoteProtocolError` exceptions. (Pull #129) +- Add `UnsupportedProtocol` exception. (Pull #128) +- Add `.get_connection_info()` method. (Pull #102, #137) +- Add better TRACE logs. (Pull #101) + +### Changed + +- `max_keepalive` is deprecated in favour of `max_keepalive_connections`. (Pull #140) + +### Fixed + +- Improve handling of server disconnects. (Pull #112) + +## 0.9.1 (May 27th, 2020) + +### Fixed + +- Proper host resolution for sync case, including IPv6 support. (Pull #97) +- Close outstanding connections when connection pool is closed. (Pull #98) + +## 0.9.0 (May 21th, 2020) + +### Changed + +- URL port becomes an `Optional[int]` instead of `int`. (Pull #92) + +### Fixed + +- Honor HTTP/2 max concurrent streams settings. (Pull #89, #90) +- Remove incorrect debug log. (Pull #83) + +## 0.8.4 (May 11th, 2020) + +### Added + +- Logging via HTTPCORE_LOG_LEVEL and HTTPX_LOG_LEVEL environment variables +and TRACE level logging.

Various optionally supported features might require specification of custom +extra require, e.g. `pip install fsspec[ssh]` will install dependencies for `ssh` backends support. +Use `pip install fsspec[full]` for installation of all known extra dependencies. + +Up-to-date package also provided through conda-forge distribution: + +```bash +conda install -c conda-forge fsspec +``` + + +## Purpose + +To produce a template or specification for a file-system interface, that specific implementations should follow, +so that applications making use of them can rely on a common behaviour and not have to worry about the specific +internal implementation decisions with any given backend. Many such implementations are included in this package, +or in sister projects such as `s3fs` and `gcsfs`. + +In addition, if this is well-designed, then additional functionality, such as a key-value store or FUSE +mounting of the file-system implementation may be available for all implementations "for free". + +## Documentation + +Please refer to [RTD](https://filesystem-spec.readthedocs.io/en/latest/?badge=latest) + +## Develop + +fsspec uses GitHub Actions for CI. Environment files can be found +in the "ci/" directory. Note that the main environment is called "py38", +but it is expected that the version of python installed be adjustable at +CI runtime. For local use, pick a version suitable for you. + +```bash +# For a new environment (mamba / conda). +mamba create -n fsspec -c conda-forge python=3.10 -y +conda activate fsspec + +# Standard dev install with docs and tests. +pip install -e ".[dev,doc,test]" + +# Full tests except for downstream +pip install s3fs +pip uninstall s3fs +pip install -e .[dev,doc,test_full] +pip install s3fs --no-deps +pytest -v + +# Downstream tests. +sh install_s3fs.sh +# Windows powershell. +install_s3fs.sh +``` + +### Testing + +Tests can be run in the dev environment, if activated, via ``pytest fsspec``. + +The full fsspec suite requires a system-level docker, docker-compose, and fuse +installation. If only making changes to one backend implementation, it is +not generally necessary to run all tests locally. + +It is expected that contributors ensure that any change to fsspec does not +cause issues or regressions for either other fsspec-related packages such +as gcsfs and s3fs, nor for downstream users of fsspec. The "downstream" CI +run and corresponding environment file run a set of tests from the dask +test suite, and very minimal tests against pandas and zarr from the +test_downstream.py module in this repo. + +### Code Formatting + +fsspec uses [Black](https://black.readthedocs.io/en/stable) to ensure +a consistent code format throughout the project. +Run ``black fsspec`` from the root of the filesystem_spec repository to +auto-format your code. Additionally, many editors have plugins that will apply +``black`` as you edit files. ``black`` is included in the ``tox`` environments. + +Optionally, you may wish to setup [pre-commit hooks](https://pre-commit.com) to +automatically run ``black`` when you make a git commit. +Run ``pre-commit install --install-hooks`` from the root of the +filesystem_spec repository to setup pre-commit hooks. ``black`` will now be run +before you commit, reformatting any changed files. You can format without +committing via ``pre-commit run`` or skip these checks with ``git commit +--no-verify``. + +## Support + +Work on this repository is supported in part by: + +"Anaconda, Inc. -

HTTPX - A next-generation HTTP client for Python.

+ +

+ + Test Suite + + + Package version + +

+ +HTTPX is a fully featured HTTP client library for Python 3. It includes **an integrated command line client**, has support for both **HTTP/1.1 and HTTP/2**, and provides both **sync and async APIs**. + +--- + +Install HTTPX using pip: + +```shell +$ pip install httpx +``` + +Now, let's get started: + +```pycon +>>> import httpx +>>> r = httpx.get('https://www.example.org/') +>>> r + +>>> r.status_code +200 +>>> r.headers['content-type'] +'text/html; charset=UTF-8' +>>> r.text +'\n\n\nExample Domain...' +``` + +Or, using the command-line client. + +```shell +$ pip install 'httpx[cli]' # The command line client is an optional dependency. +``` + +Which now allows us to use HTTPX directly from the command-line... + +

+ httpx --help +

+ +Sending a request... + +

+ httpx http://httpbin.org/json +

+ +## Features + +HTTPX builds on the well-established usability of `requests`, and gives you: + +* A broadly [requests-compatible API](https://www.python-httpx.org/compatibility/). +* An integrated command-line client. +* HTTP/1.1 [and HTTP/2 support](https://www.python-httpx.org/http2/). +* Standard synchronous interface, but with [async support if you need it](https://www.python-httpx.org/async/). +* Ability to make requests directly to [WSGI applications](https://www.python-httpx.org/advanced/transports/#wsgi-transport) or [ASGI applications](https://www.python-httpx.org/advanced/transports/#asgi-transport). +* Strict timeouts everywhere. +* Fully type annotated. +* 100% test coverage. + +Plus all the standard features of `requests`... + +* International Domains and URLs +* Keep-Alive & Connection Pooling +* Sessions with Cookie Persistence +* Browser-style SSL Verification +* Basic/Digest Authentication +* Elegant Key/Value Cookies +* Automatic Decompression +* Automatic Content Decoding +* Unicode Response Bodies +* Multipart File Uploads +* HTTP(S) Proxy Support +* Connection Timeouts +* Streaming Downloads +* .netrc Support +* Chunked Requests + +## Installation + +Install with pip: + +```shell +$ pip install httpx +``` + +Or, to include the optional HTTP/2 support, use: + +```shell +$ pip install httpx[http2] +``` + +HTTPX requires Python 3.8+. + +## Documentation + +Project documentation is available at [https://www.python-httpx.org/](https://www.python-httpx.org/). + +For a run-through of all the basics, head over to the [QuickStart](https://www.python-httpx.org/quickstart/). + +For more advanced topics, see the [Advanced Usage](https://www.python-httpx.org/advanced/) section, the [async support](https://www.python-httpx.org/async/) section, or the [HTTP/2](https://www.python-httpx.org/http2/) section. + +The [Developer Interface](https://www.python-httpx.org/api/) provides a comprehensive API reference. + +To find out about tools that integrate with HTTPX, see [Third Party Packages](https://www.python-httpx.org/third_party_packages/). + +## Contribute + +If you want to contribute with HTTPX check out the [Contributing Guide](https://www.python-httpx.org/contributing/) to learn how to start. + +## Dependencies + +The HTTPX project relies on these excellent libraries: + +* `httpcore` - The underlying transport implementation for `httpx`. + * `h11` - HTTP/1.1 support. +* `certifi` - SSL certificates. +* `idna` - Internationalized domain name support. +* `sniffio` - Async library autodetection. + +As well as these optional installs: + +* `h2` - HTTP/2 support. *(Optional, with `httpx[http2]`)* +* `socksio` - SOCKS proxy support. *(Optional, with `httpx[socks]`)* +* `rich` - Rich terminal support. *(Optional, with `httpx[cli]`)* +* `click` - Command line client support. *(Optional, with `httpx[cli]`)* +* `brotli` or `brotlicffi` - Decoding for "brotli" compressed responses. *(Optional, with `httpx[brotli]`)* +* `zstandard` - Decoding for "zstd" compressed responses. *(Optional, with `httpx[zstd]`)* + +A huge amount of credit is due to `requests` for the API layout that +much of this work follows, as well as to `urllib3` for plenty of design +inspiration around the lower-level networking details. + +--- + +

HTTPX is BSD licensed code.
Designed & crafted with care.

For example, this +can be used to redirect the messages writing to a log file or class. + +Redirecting writing +~~~~~~~~~~~~~~~~~~~ + +If using a library that can print messages to the console, editing the library +by replacing ``print()`` with ``tqdm.write()`` may not be desirable. +In that case, redirecting ``sys.stdout`` to ``tqdm.write()`` is an option. + +To redirect ``sys.stdout``, create a file-like class that will write +any input string to ``tqdm.write()``, and supply the arguments +``file=sys.stdout, dynamic_ncols=True``. + +A reusable canonical example is given below: + +.. code:: python + + from time import sleep + import contextlib + import sys + from tqdm import tqdm + from tqdm.contrib import DummyTqdmFile + + + @contextlib.contextmanager + def std_out_err_redirect_tqdm(): + orig_out_err = sys.stdout, sys.stderr + try: + sys.stdout, sys.stderr = map(DummyTqdmFile, orig_out_err) + yield orig_out_err[0] + # Relay exceptions + except Exception as exc: + raise exc + # Always restore sys.stdout/err if necessary + finally: + sys.stdout, sys.stderr = orig_out_err + + def some_fun(i): + print("Fee, fi, fo,".split()[i]) + + # Redirect stdout to tqdm.write() (don't forget the `as save_stdout`) + with std_out_err_redirect_tqdm() as orig_stdout: + # tqdm needs the original stdout + # and dynamic_ncols=True to autodetect console width + for i in tqdm(range(3), file=orig_stdout, dynamic_ncols=True): + sleep(.5) + some_fun(i) + + # After the `with`, printing is restored + print("Done!") + +Redirecting ``logging`` +~~~~~~~~~~~~~~~~~~~~~~~ + +Similar to ``sys.stdout``/``sys.stderr`` as detailed above, console ``logging`` +may also be redirected to ``tqdm.write()``. + +Warning: if also redirecting ``sys.stdout``/``sys.stderr``, make sure to +redirect ``logging`` first if needed. + +Helper methods are available in ``tqdm.contrib.logging``. For example: + +.. code:: python + + import logging + from tqdm import trange + from tqdm.contrib.logging import logging_redirect_tqdm + + LOG = logging.getLogger(__name__) + + if __name__ == '__main__': + logging.basicConfig(level=logging.INFO) + with logging_redirect_tqdm(): + for i in trange(9): + if i == 4: + LOG.info("console logging redirected to `tqdm.write()`") + # logging restored + +Monitoring thread, intervals and miniters +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +``tqdm`` implements a few tricks to increase efficiency and reduce overhead. + +- Avoid unnecessary frequent bar refreshing: ``mininterval`` defines how long + to wait between each refresh. ``tqdm`` always gets updated in the background, + but it will display only every ``mininterval``. +- Reduce number of calls to check system clock/time. +- ``mininterval`` is more intuitive to configure than ``miniters``. + A clever adjustment system ``dynamic_miniters`` will automatically adjust + ``miniters`` to the amount of iterations that fit into time ``mininterval``. + Essentially, ``tqdm`` will check if it's time to print without actually + checking time. This behaviour can be still be bypassed by manually setting + ``miniters``. + +However, consider a case with a combination of fast and slow iterations. +After a few fast iterations, ``dynamic_miniters`` will set ``miniters`` to a +large number. When iteration rate subsequently slows, ``miniters`` will +remain large and thus reduce display update frequency. To address this: + +- ``maxinterval`` defines the maximum time between display refreshes. + A concurrent monitoring thread checks for overdue updates and forces one + where necessary. + +The monitoring thread should not have a noticeable overhead, and guarantees +updates at least every 10 seconds by default. +This value can be directly changed by setting the ``monitor_interval`` of +any ``tqdm`` instance (i.e. ``t = tqdm.tqdm(...); t.monitor_interval = 2``). +The monitor thread may be disabled application-wide by setting +``tqdm.tqdm.monitor_interval = 0`` before instantiation of any ``tqdm`` bar. + + +Merch +----- + +You can buy `tqdm branded merch `__ now! + +Contributions +------------- + +|GitHub-Commits| |GitHub-Issues| |GitHub-PRs| |OpenHub-Status| |GitHub-Contributions|

+\-\-mininterval=\f[I]mininterval\f[R] +float, optional. +Minimum progress display update interval [default: 0.1] seconds. +.TP +\-\-maxinterval=\f[I]maxinterval\f[R] +float, optional. +Maximum progress display update interval [default: 10] seconds. +Automatically adjusts \f[CR]miniters\f[R] to correspond to +\f[CR]mininterval\f[R] after long display update lag. +Only works if \f[CR]dynamic_miniters\f[R] or monitor thread is enabled. +.TP +\-\-miniters=\f[I]miniters\f[R] +int or float, optional. +Minimum progress display update interval, in iterations. +If 0 and \f[CR]dynamic_miniters\f[R], will automatically adjust to equal +\f[CR]mininterval\f[R] (more CPU efficient, good for tight loops). +If > 0, will skip display of specified number of iterations. +Tweak this and \f[CR]mininterval\f[R] to get very efficient loops. +If your progress is erratic with both fast and slow iterations (network, +skipping items, etc) you should set miniters=1. +.TP +\-\-ascii=\f[I]ascii\f[R] +bool or str, optional. +If unspecified or False, use unicode (smooth blocks) to fill the meter. +The fallback is to use ASCII characters \(rq 123456789#\(lq. +.TP +\-\-disable +bool, optional. +Whether to disable the entire progress bar wrapper [default: False]. +If set to None, disable on non\-TTY. +.TP +\-\-unit=\f[I]unit\f[R] +str, optional. +String that will be used to define the unit of each iteration [default: +it]. +.TP +\-\-unit\-scale=\f[I]unit_scale\f[R] +bool or int or float, optional. +If 1 or True, the number of iterations will be reduced/scaled +automatically and a metric prefix following the International System of +Units standard will be added (kilo, mega, etc.) +[default: False]. +If any other non\-zero number, will scale \f[CR]total\f[R] and +\f[CR]n\f[R]. +.TP +\-\-dynamic\-ncols +bool, optional. +If set, constantly alters \f[CR]ncols\f[R] and \f[CR]nrows\f[R] to the +environment (allowing for window resizes) [default: False]. +.TP +\-\-smoothing=\f[I]smoothing\f[R] +float, optional. +Exponential moving average smoothing factor for speed estimates (ignored +in GUI mode). +Ranges from 0 (average speed) to 1 (current/instantaneous speed) +[default: 0.3]. +.TP +\-\-bar\-format=\f[I]bar_format\f[R] +str, optional. +Specify a custom bar string formatting. +May impact performance. +[default: `{l_bar}{bar}{r_bar}'], where l_bar=`{desc}: +{percentage:3.0f}%|' and r_bar=`| {n_fmt}/{total_fmt} +[{elapsed}<{remaining}, \(cq \(cq{rate_fmt}{postfix}]' Possible vars: +l_bar, bar, r_bar, n, n_fmt, total, total_fmt, percentage, elapsed, +elapsed_s, ncols, nrows, desc, unit, rate, rate_fmt, rate_noinv, +rate_noinv_fmt, rate_inv, rate_inv_fmt, postfix, unit_divisor, +remaining, remaining_s, eta. +Note that a trailing \(lq:\(rq is automatically removed after {desc} if +the latter is empty. +.TP +\-\-initial=\f[I]initial\f[R] +int or float, optional. +The initial counter value. +Useful when restarting a progress bar [default: 0]. +If using float, consider specifying \f[CR]{n:.3f}\f[R] or similar in +\f[CR]bar_format\f[R], or specifying \f[CR]unit_scale\f[R]. +.TP +\-\-position=\f[I]position\f[R] +int, optional. +Specify the line offset to print this bar (starting from 0) Automatic if +unspecified. +Useful to manage multiple bars at once (eg, from threads). +.TP +\-\-postfix=\f[I]postfix\f[R] +dict or *, optional. +Specify additional stats to display at the end of the bar. +Calls \f[CR]set_postfix(**postfix)\f[R] if possible (dict). +.TP +\-\-unit\-divisor=\f[I]unit_divisor\f[R] +float, optional. +[default: 1000], ignored unless \f[CR]unit_scale\f[R] is True. +.TP +\-\-write\-bytes +bool, optional. +Whether to write bytes. +If (default: False) will write unicode. +.TP +\-\-lock\-args=\f[I]lock_args\f[R] +tuple, optional. +Passed to \f[CR]refresh\f[R] for intermediate output (initialisation, +iterating, and updating). +.TP +\-\-nrows=\f[I]nrows\f[R] +int, optional. +The screen height. +If specified, hides nested bars outside this bound. +If unspecified, attempts to use environment height. +The fallback is 20. +.TP +\-\-colour=\f[I]colour\f[R] +str, optional. +Bar colour (e.g.\ `green', `#00ff00'). +.TP +\-\-delay=\f[I]delay\f[R] +float, optional. +Don\(cqt display until [default: 0] seconds have elapsed. +.TP +\-\-delim=\f[I]delim\f[R] +chr, optional. +Delimiting character [default: `\(rsn']. +Use `\(rs0' for null. +N.B.: on Windows systems, Python converts `\(rsn' to `\(rsr\(rsn'. +.TP +\-\-buf\-size=\f[I]buf_size\f[R] +int, optional. +String buffer size in bytes [default: 256] used when \f[CR]delim\f[R] is +specified. +.TP +\-\-bytes +bool, optional. +If true, will count bytes, ignore \f[CR]delim\f[R], and default +\f[CR]unit_scale\f[R] to True, \f[CR]unit_divisor\f[R] to 1024, and +\f[CR]unit\f[R] to `B'. +.TP +\-\-tee +bool, optional. +If true, passes \f[CR]stdin\f[R] to both \f[CR]stderr\f[R] and +\f[CR]stdout\f[R]. +.TP +\-\-update +bool, optional. +If true, will treat input as newly elapsed iterations, i.e.\ numbers to +pass to \f[CR]update()\f[R]. +Note that this is slow (\(ti2e5 it/s) since every input must be decoded +as a number. +.TP +\-\-update\-to +bool, optional. +If true, will treat input as total elapsed iterations, i.e.\ numbers to +assign to \f[CR]self.n\f[R]. +Note that this is slow (\(ti2e5 it/s) since every input must be decoded +as a number. +.TP +\-\-null +bool, optional. +If true, will discard input (no stdout). +.TP +\-\-manpath=\f[I]manpath\f[R] +str, optional. +Directory in which to install tqdm man pages. +.TP +\-\-comppath=\f[I]comppath\f[R] +str, optional. +Directory in which to place tqdm completion. +.TP
