#
# Martin von Loewis, who wrote the initial implementation of the underlying

# gettext.py implementation.
#
# Peter Funk, who wrote fintl.py, a fairly complete wrapper around intlmodule,
# which also included a pure-Python implementation to read .mo files if
# intlmodule wasn't available.
#
# James Henstridge, who also wrote a gettext.py module, which has some
# interesting, but currently unsupported experimental features: the notion of
# a Catalog class and instances, and the ability to add to a catalog file via
# a Python API.
#
# Barry Warsaw integrated these modules, wrote the .install() API and code,
# and conformed all C and Python code to Python's coding standards.
#
# Francois Pinard and Marc-Andre Lemburg also contributed valuably to this
# module.
#
# J. David Ibanez implemented plural forms. Bruno Haible fixed some bugs.
#
# TODO:

Otherwise, exactly one of the following three options must be given:
-t, --trace Print each line to sys.stdout before it is executed.
-c, --count Count the number of times each line is executed
and write the counts to <module>.cover for each
module executed, in the module's directory.
See also `--coverdir', `--file', `--no-report' below.
-l, --listfuncs Keep track of which functions are executed at least
once and write the results to sys.stdout after the
program exits.
-T, --trackcalls Keep track of caller/called pairs and write the
results to sys.stdout after the program exits.
-r, --report Generate a report from a counts file; do not execute
any code. `--file' must specify the results file to
read, which must have been created in a previous run
with `--count --file=FILE'.
Modifiers:
-f, --file=<file> File to accumulate counts over several runs.
-R, --no-report Do not generate the coverage report files.
Useful if you want to accumulate over several runs.
-C, --coverdir=<dir> Directory where the report files. The coverage
report for <package>.<module> is written to file
<dir>/<package>/<module>.cover.
-m, --missing Annotate executable lines that were not executed
with '>>>>>> '.
-s, --summary Write a brief summary on stdout for each file.
(Can only be used with --count or --report.)
-g, --timing Prefix each line with the time since the program started.
Only used while tracing.
Filters, may be repeated multiple times:
--ignore-module=<mod> Ignore the given module(s) and its submodules
(if it is a package). Accepts comma separated
list of module names
--ignore-dir=<dir> Ignore files in the given directory (multiple

# Module doctest.
# Released to the public domain 16-Jan-2001, by Tim Peters (tim@python.org).
# Major enhancements and refactoring by:
# Jim Fulton
# Edward Loper
# Provided as-is; use at your own risk; no warranty; no promises; enjoy!
r"""Module doctest -- a framework for running examples in docstrings.
In simplest use, end each module M to be tested with:
def _test():
import doctest
doctest.testmod()
if __name__ == "__main__":
_test()
Then running the module as a script will cause the examples in the
docstrings to get executed and verified:
python M.py
This won't display anything unless an example fails, in which case the
failing example(s) and the cause(s) of the failure(s) are printed to stdout
(why not stderr? because stderr is a lame hack <0.2 wink>), and the final
line of output is "Test failed.".
Run it with the -v switch instead:
python M.py -v
and a detailed report of all examples tried is printed to stdout, along
with assorted summaries at the end.
You can force verbose mode by passing "verbose=True" to testmod, or prohibit
it by passing "verbose=False". In either of those cases, sys.argv is not
examined by testmod.
There are a variety of other ways to run doctests, including integration
with the unittest framework, and support for running non-Python text
files containing doctests. There are also many ways to override parts
of doctest's default behaviors. See the Library Reference Manual for
details.

## 2. Example & DocTest
######################################################################
## - An "example" is a <source, want> pair, where "source" is a
## fragment of source code, and "want" is the expected output for
## "source." The Example class also includes information about
## where the example was extracted from.
##
## - A "doctest" is a collection of examples, typically extracted from
## a string (such as an object's docstring). The DocTest class also
## includes information about where the string was extracted from.
class Example:
"""
A single doctest example, consisting of source code and expected
output. `Example` defines the following attributes:
- source: A single Python statement, always ending with a newline.
The constructor adds a newline if needed.
- want: The expected output from running the source code (either
from stdout, or a traceback in case of exception). `want` ends
with a newline unless it's empty, in which case it's an empty
string. The constructor adds a newline if needed.
- exc_msg: The exception message generated by the example, if
the example is expected to generate an exception; or `None` if
it is not expected to generate an exception. This exception
message is compared against the return value of
`traceback.format_exception_only()`. `exc_msg` ends with a
newline unless it's `None`. The constructor adds a newline
if needed.
- lineno: The line number within the DocTest string containing
this Example where the Example begins. This line number is
zero-based, with respect to the beginning of the DocTest.
- indent: The example's indentation in the DocTest string.
I.e., the number of space characters that preceed the
example's first prompt.
- options: A dictionary mapping from option flags to True or
False, which is used to override default options for this
example. Any option flags not contained in this dictionary
are left at their default value (as specified by the
DocTestRunner's optionflags). By default, no options are set.

the test finder will attempt to automatically determine the
correct module. The object's module is used:
- As a default namespace, if `globs` is not specified.
- To prevent the DocTestFinder from extracting DocTests

Contained objects whose module does not match `module` are ignored.
If `module` is False, no attempt to find the module will be made.
This is obscure, of use mostly in tests: if `module` is False, or

considered to belong to the (non-existent) module, so all contained
objects will (recursively) be searched for doctests.

in `globs`). A new copy of the globals dictionary is created

2 tests in _TestClass

1 tests in _TestClass.square
7 tests in 4 items.

Test passed.

The aggregated number of tried examples and failed examples is
also available via the `tries` and `failures` attributes:

The comparison between expected outputs and actual outputs is done
by an `OutputChecker`. This comparison may be customized with a
number of option flags; see the documentation for `testmod` for
more information. If the option flags are insufficient, then the
comparison may also be customized by passing a subclass of
`OutputChecker` to the constructor.
The test runner's display output can be controlled in two ways.
First, an output function (`out) can be passed to
`TestRunner.run`; this function will be called with strings that
should be displayed. It defaults to `sys.stdout.write`. If
capturing the output is not sufficient, then the display output
can be also customized by subclassing DocTestRunner, and
overriding the methods `report_start`, `report_success`,
`report_unexpected_exception`, and `report_failure`.

"""Conversion pipeline templates.
The problem:
------------
Suppose you have some data that you want to convert to another format,
such as from GIF image format to PPM image format. Maybe the
conversion involves several steps (e.g. piping it through compress or
uuencode). Some of the conversion steps may require that their input
is a disk file, others may be able to read standard input; similar for
their output. The input to the entire conversion may also be read
from a disk file or from an open file, and similar for its output.
The module lets you construct a pipeline template by sticking one or
more conversion steps together. It will take care of creating and
removing temporary files if they are necessary to hold intermediate
data. You can then use the template to do conversions from many
different sources to many different destinations. The temporary
file names used are different each time the template is used.
The templates are objects so you can create templates for many
different conversion steps and store them in a dictionary, for
instance.
Directions:
-----------
To create a template:
t = Template()
To add a conversion step to a template:
t.append(command, kind)
where kind is a string of two characters: the first is '-' if the
command reads its standard input or 'f' if it requires a file; the
second likewise for the output. The command must be valid /bin/sh
syntax. If input or output files are required, they are passed as
$IN and $OUT; otherwise, it must be possible to use the command in
a pipeline.
To add a conversion step at the beginning:
t.prepend(command, kind)
To convert a file to another file using a template:
sts = t.copy(infile, outfile)
If infile or outfile are the empty string, standard input is read or
standard output is written, respectively. The return value is the
exit status of the conversion pipeline.
To open a file for reading or writing through a conversion pipeline:
fp = t.open(file, mode)
where mode is 'r' to read the file, or 'w' to write it -- just like
for the built-in function open() or for os.popen().
To create a new template object initialized to a given one:
t2 = t.clone()
For an example, see the function test() at the end of the file.

file is either a text or byte string giving the name (and the path
if the file isn't in the current working directory) of the file to
be opened or an integer file descriptor of the file to be
wrapped. (If a file descriptor is given, it is closed when the
returned I/O object is closed, unless closefd is set to False.)
mode is an optional string that specifies the mode in which the file
is opened. It defaults to 'r' which means open for reading in text
mode. Other common values are 'w' for writing (truncating the file if
it already exists), and 'a' for appending (which on some Unix systems,
means that all writes append to the end of the file regardless of the
current seek position). In text mode, if encoding is not specified the
encoding used is platform dependent. (For reading and writing raw
bytes use binary mode and leave encoding unspecified.) The available
modes are:
========= ===============================================================
Character Meaning
--------- ---------------------------------------------------------------
'r' open for reading (default)
'w' open for writing, truncating the file first
'a' open for writing, appending to the end of the file if it exists
'b' binary mode
't' text mode (default)
'+' open a disk file for updating (reading and writing)
'U' universal newline mode (for backwards compatibility; unneeded
for new code)
========= ===============================================================
The default mode is 'rt' (open for reading text). For binary random
access, the mode 'w+b' opens and truncates the file to 0 bytes, while
'r+b' opens the file without truncation.
Python distinguishes between files opened in binary and text modes,
even when the underlying operating system doesn't. Files opened in
binary mode (appending 'b' to the mode argument) return contents as
bytes objects without any decoding. In text mode (the default, or when
't' is appended to the mode argument), the contents of the file are
returned as strings, the bytes having been first decoded using a
platform-dependent encoding or using the specified encoding if given.
buffering is an optional integer used to set the buffering policy.
Pass 0 to switch buffering off (only allowed in binary mode), 1 to select
line buffering (only usable in text mode), and an integer > 1 to indicate
the size of a fixed-size chunk buffer. When no buffering argument is
given, the default buffering policy works as follows:
* Binary files are buffered in fixed-size chunks; the size of the buffer
is chosen using a heuristic trying to determine the underlying device's
"block size" and falling back on `io.DEFAULT_BUFFER_SIZE`.
On many systems, the buffer will typically be 4096 or 8192 bytes long.
* "Interactive" text files (files for which isatty() returns True)
use line buffering. Other text files use the policy described above
for binary files.
encoding is the name of the encoding used to decode or encode the
file. This should only be used in text mode. The default encoding is
platform dependent, but any encoding supported by Python can be
passed. See the codecs module for the list of supported encodings.
errors is an optional string that specifies how encoding errors are to
be handled---this argument should not be used in binary mode. Pass
'strict' to raise a ValueError exception if there is an encoding error
(the default of None has the same effect), or pass 'ignore' to ignore
errors. (Note that ignoring encoding errors can lead to data loss.)
See the documentation for codecs.register for a list of the permitted
encoding error strings.
newline controls how universal newlines works (it only applies to text
mode). It can be None, '', '\n', '\r', and '\r\n'. It works as
follows:
* On input, if newline is None, universal newlines mode is
enabled. Lines in the input can end in '\n', '\r', or '\r\n', and
these are translated into '\n' before being returned to the
caller. If it is '', universal newline mode is enabled, but line
endings are returned to the caller untranslated. If it has any of
the other legal values, input lines are only terminated by the given
string, and the line ending is returned to the caller untranslated.
* On output, if newline is None, any '\n' characters written are
translated to the system default line separator, os.linesep. If
newline is '', no translation takes place. If newline is any of the
other legal values, any '\n' characters written are translated to
the given string.
If closefd is False, the underlying file descriptor will be kept open
when the file is closed. This does not work when a file name is given
and must be True in that case.
open() returns a file object whose type depends on the mode, and
through which the standard file operations such as reading and writing
are performed. When open() is used to open a file in a text mode ('w',
'r', 'wt', 'rt', etc.), it returns a TextIOWrapper. When used to open
a file in a binary mode, the returned class varies: in read binary
mode, it returns a BufferedReader; in write binary and append binary
modes, it returns a BufferedWriter, and in read/write mode, it returns
a BufferedRandom.
It is also possible to use a string or bytearray as a file for both
reading and writing. For strings StringIO can be used like a file
opened in a text mode, and for bytes a BytesIO can be used like a file
opened in a binary mode.

This class provides dummy implementations for many methods that
derived classes can override selectively; the default implementations
represent a file that cannot be read, written or seeked.
Even though IOBase does not declare read, readinto, or write because
their signatures will vary, implementations and clients should
consider those methods part of the interface. Also, implementations
may raise a IOError when operations they do not support are called.
The basic type used for binary data read from or written to a file is
bytes. bytearrays are accepted too, and in some cases (such as
readinto) needed. Text I/O classes work with str data.
Note that calling any method (even inquiries) on a closed stream is
undefined. Implementations may raise IOError in this case.
IOBase (and its subclasses) support the iterator protocol, meaning
that an IOBase object can be iterated over yielding the lines in a
stream.
IOBase also supports the :keyword:`with` statement. In this example,
fp is closed after the suite of the with statement is complete:
with open('spam.txt', 'r') as fp:
fp.write('Spam and eggs!')

Methods:
__init__()

startbody()
startmultipartbody()
nextpart()
lastpart()
A MIME writer is much more primitive than a MIME parser. It
doesn't seek around on the output file, and it doesn't use large
amounts of buffer space, so you have to write the parts in the
order they should occur on the output file. It does buffer the
headers you add, allowing you to rearrange their order.
General usage is:
f = <open the output file>
w = MimeWriter(f)
...call w.addheader(key, value) 0 or more times...
followed by either:
f = w.startbody(content_type)
...call f.write(data) for body data...
or:
w.startmultipartbody(subtype)
for each part:
subwriter = w.nextpart()
...use the subwriter's methods to create the subpart...
w.lastpart()
The subwriter is another MimeWriter instance, and should be
treated in the same way as the toplevel MimeWriter. This way,
writing recursive body parts is easy.
Warning: don't forget to call lastpart()!
XXX There should be more state so calls made in the wrong order
are detected.
Some special cases:
- startbody() just returns the file passed to the constructor;
but don't use this knowledge, as it may be changed.
- startmultipartbody() actually returns a file as well;
this can be used to write the initial 'if you can read this your
mailer is not MIME-aware' message.
- If you call flushheaders(), the headers accumulated so far are
written out (and forgotten); this is useful if you don't need a
body part at all, e.g. for a subpart of type message/rfc822
that's (mis)used to store some header-like information.
- Passing a keyword argument 'prefix=<flag>' to addheader(),
start*body() affects where the header is inserted; 0 means
append at the end, 1 means insert at the start; default is
append for addheader(), but insert for start*body(), which use
it to determine where the Content-Type header goes.

Formatter objects transform an abstract flow of formatting events into

paragraph separation.

WARNING: you may want to backup your browser's cookies file if you use
this class to save cookies. I *think* it works, but there have been
bugs in the past!
This class differs from CookieJar only in the format it uses to save and
load cookies to and from a file. This class uses the Mozilla/Netscape
`cookies.txt' format. lynx uses this file format, too.
Don't expect cookies saved while the browser is running to be noticed by
the browser (in fact, Mozilla on unix will overwrite your saved cookies if
you change them on disk while it's running; on Windows, you probably can't
save at all while the browser is running).
Note that the Mozilla/Netscape format will downgrade RFC2965 cookies to
Netscape cookies on saving.
In particular, the cookie version and port number information is lost,
together with information about whether or not Path, Port and Discard were
specified by the Set-Cookie2 (or Set-Cookie) header, and whether or not the
domain as set in the HTTP header started with a dot (yes, I'm aware some
domains in Netscape files start with a dot and some don't -- trust me, you
really don't want to know any more about this).
Note that though Mozilla and Netscape use the same format, they use
slightly different headers. The class saves cookies using the Netscape
header by default (Mozilla can cope with that).

A mutex has two pieces of state -- a 'locked' bit and a queue.

When the mutex is unlocked while the queue is not empty,
the first queue entry is removed and its function(argument) pair called,

Of course, no multi-threading is implied -- hence the funny interface

At least one of fileobj and filename must be given a
non-trivial value.
The new class instance is based on fileobj, which can be a regular
file, a StringIO object, or any other object which simulates a file.
It defaults to None, in which case filename is opened to provide
a file object.
When fileobj is not None, the filename argument is only used to be
included in the gzip file header, which may includes the original
filename of the uncompressed file. It defaults to the filename of
fileobj, if discernible; otherwise, it defaults to the empty string,
and in this case the original filename is not included in the header.
The mode argument can be any of 'r', 'rb', 'a', 'ab', 'w', or 'wb',
depending on whether the file will be read or written. The default
is the mode of fileobj if discernible; otherwise, the default is 'rb'.
Be aware that only the 'rb', 'ab', and 'wb' values should be used
for cross-platform portability.
The compresslevel argument is an integer from 1 to 9 controlling the
level of compression; 1 is fastest and produces the least compression,
and 9 is slowest and produces the most compression. The default is 9.
The mtime argument is an optional numeric timestamp to be written
to the stream when compressing. All gzip compressed streams
are required to contain a timestamp. If omitted or None, the
current time is used. This module ignores the timestamp when
decompressing; however, some programs, such as gunzip, make use
of it. The format of the timestamp is the same as that of the
return value of time.time() and of the st_mtime member of the
object returned by os.stat().

objects decoded by this instance (utf-8 by default). It has no
effect when decoding ``unicode`` objects.
Note that currently only encodings that are a superset of ASCII work,
strings of other encodings should be passed in as ``unicode``.
``object_hook``, if specified, will be called with the result
of every JSON object decoded and its return value will be used in
place of the given ``dict``. This can be used to provide custom
deserializations (e.g. to support JSON-RPC class hinting).
``object_pairs_hook``, if specified will be called with the result of
every JSON object decoded with an ordered list of pairs. The return
value of ``object_pairs_hook`` will be used instead of the ``dict``.
This feature can be used to implement custom decoders that rely on the
order that the key and value pairs are decoded (for example,
collections.OrderedDict will remember the order of insertion). If
``object_hook`` is also defined, the ``object_pairs_hook`` takes
priority.
``parse_float``, if specified, will be called with the string
of every JSON float to be decoded. By default this is equivalent to
float(num_str). This can be used to use another datatype or parser
for JSON floats (e.g. decimal.Decimal).
``parse_int``, if specified, will be called with the string
of every JSON int to be decoded. By default this is equivalent to
int(num_str). This can be used to use another datatype or parser
for JSON integers (e.g. float).
``parse_constant``, if specified, will be called with one of the
following strings: -Infinity, Infinity, NaN.
This can be used to raise an exception if invalid JSON numbers
are encountered.
If ``strict`` is false (true is the default), then control
characters will be allowed inside strings. Control characters in
this context are those with character codes in the 0-31 range,
including ``'\\t'`` (tab), ``'\\n'``, ``'\\r'`` and ``'\\0'``.

If ensure_ascii is true, the output is guaranteed to be str
objects with all incoming unicode characters escaped. If
ensure_ascii is false, the output will be unicode object.
If check_circular is true, then lists, dicts, and custom encoded
objects will be checked for circular references during encoding to
prevent an infinite recursion (which would cause an OverflowError).
Otherwise, no such check takes place.
If allow_nan is true, then NaN, Infinity, and -Infinity will be
encoded as such. This behavior is not JSON specification compliant,
but is consistent with most JavaScript based encoders and decoders.
Otherwise, it will be a ValueError to encode such floats.

sorted by key; this is useful for regression tests to ensure
that JSON serializations can be compared on a day-to-day basis.

r"""JSON (JavaScript Object Notation) <http://json.org> is a subset of
JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
interchange format.
:mod:`json` exposes an API familiar to users of the standard library
:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
version of the :mod:`json` library contained in Python 2.6, but maintains
compatibility with Python 2.4 and Python 2.5 and (currently) has
significant performance advantages, even without using the optional C
extension for speedups.
Encoding basic Python object hierarchies::
>>> import json
>>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
'["foo", {"bar": ["baz", null, 1.0, 2]}]'
>>> print json.dumps("\"foo\bar")
"\"foo\bar"
>>> print json.dumps(u'\u1234')
"\u1234"
>>> print json.dumps('\\')
"\\"
>>> print json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)
{"a": 0, "b": 0, "c": 0}
>>> from StringIO import StringIO
>>> io = StringIO()
>>> json.dump(['streaming API'], io)
>>> io.getvalue()
'["streaming API"]'
Compact encoding::
>>> import json
>>> json.dumps([1,2,3,{'4': 5, '6': 7}], separators=(',',':'))
'[1,2,3,{"4":5,"6":7}]'
Pretty printing::
>>> import json
>>> s = json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
>>> print '\n'.join([l.rstrip() for l in s.splitlines()])
{
"4": 5,

"""Append module search paths for third-party packages to sys.path.
****************************************************************
* This module is automatically imported during initialization. *
****************************************************************
In earlier versions of Python (up to 1.5a3), scripts or modules that
needed to use site-specific modules would place ``import site''
somewhere near the top of their code. Because of the automatic
import, this is no longer necessary (but code that does it still
works).
This will append site-specific paths to the module search path. On
Unix (including Mac OSX), it starts with sys.prefix and
sys.exec_prefix (if different) and appends
lib/python<version>/site-packages as well as lib/site-python.
On other platforms (such as Windows), it tries each of the
prefixes directly, as well as with lib/site-packages appended. The
resulting directories, if they exist, are appended to sys.path, and
also inspected for path configuration files.
A path configuration file is a file whose name has the form
<package>.pth; its contents are additional directories (one per line)
to be added to sys.path. Non-existing directories (or
non-directories) are never added to sys.path; no directory is added to
sys.path more than once. Blank lines and lines beginning with
'#' are skipped. Lines starting with 'import' are executed.
For example, suppose sys.prefix and sys.exec_prefix are set to
/usr/local and there is a directory /usr/local/lib/python2.5/site-packages
with three subdirectories, foo, bar and spam, and two path
configuration files, foo.pth and bar.pth. Assume foo.pth contains the
following:
# foo package configuration
foo
bar
bletch
and bar.pth contains:
# bar package configuration
bar
Then the following directories are added to sys.path, in this order:
/usr/local/lib/python2.5/site-packages/bar
/usr/local/lib/python2.5/site-packages/foo
Note that bletch is omitted because it doesn't exist; bar precedes foo
because bar.pth comes alphabetically before foo.pth; and spam is
omitted because it is not mentioned in either path configuration file.
After these path manipulations, an attempt is made to import a module
named sitecustomize, which can perform arbitrary additional
site-specific customizations. If this import fails with an
ImportError exception, it is silently ignored.

""" Encoding Aliases Support
This module is used by the encodings package search function to
map encodings names to module names.
Note that the search function normalizes the encoding names before
doing the lookup, so the mapping will have to map normalized
encoding names to module names.
Contents:
The following aliases dictionary contains mappings of all IANA
character set names for which the Python core library provides
codecs. In addition to these, a few Python specific codec
aliases have also been added.
