tools package¶
Miscellaneous helper functions (not wiki-dependent).
- exception pywikibot.tools.CombinedError[source]¶
Bases:
KeyError
,IndexError
An error that gets caught by both KeyError and IndexError.
New in version 3.0.
- class pywikibot.tools.ComparableMixin[source]¶
Bases:
object
Mixin class to allow comparing to other objects which are comparable.
New in version 3.0.
- class pywikibot.tools.DequeGenerator[source]¶
Bases:
collections.abc.Iterator
,collections.deque
A generator that allows items to be added during generating.
New in version 3.0.
Changed in version 6.1: Provide a representation string.
- class pywikibot.tools.EmptyDefault[source]¶
Bases:
str
,collections.abc.Mapping
A default for a not existing siteinfo property.
It should be chosen if there is no better default known. It acts like an empty collections, so it can be iterated through it safely if treated as a list, tuple, set or dictionary. It is also basically an empty string.
Accessing a value via __getitem__ will result in a combined KeyError and IndexError.
New in version 3.0.
Changed in version 6.2:
empty_iterator()
was removed in favour ofiter()
.Initialise the default as an empty string.
- Return type
None
- class pywikibot.tools.MediaWikiVersion(version_str)[source]¶
Bases:
object
Version object to allow comparing ‘wmf’ versions with normal ones.
The version mainly consist of digits separated by periods. After that is a suffix which may only be ‘wmf<number>’, ‘alpha’, ‘beta<number>’ or ‘-rc.<number>’ (the - and . are optional). They are considered from old to new in that order with a version number without suffix is considered the newest. This secondary difference is stored in an internal _dev_version attribute.
Two versions are equal if their normal version and dev version are equal. A version is greater if the normal version or dev version is greater. For example:
1.34 < 1.34.1 < 1.35wmf1 < 1.35alpha < 1.35beta1 < 1.35beta2 < 1.35-rc-1 < 1.35-rc.2 < 1.35
Any other suffixes are considered invalid.
New in version 3.0.
Changed in version 6.1: Dependency of distutils was dropped because the package will be removed with Python 3.12.
- Parameters
version_str (str) – version to parse

None
- MEDIAWIKI_VERSION = re.compile('(\\d+(?:\\.\\d+)+)(-?wmf\\.?(\\d+)|alpha|beta(\\d+)|-?rc\\.?(\\d+)|.*)?$')¶
- class pywikibot.tools.RLock(*args, **kwargs)[source]¶
Bases:
object
Context manager which implements extended reentrant lock objects.
This RLock is implicit derived from threading.RLock but provides a locked() method like in threading.Lock and a count attribute which gives the active recursion level of locks.
Usage:
>>> from pywikibot.tools import RLock >>> lock = RLock() >>> lock.acquire() True >>> with lock: print(lock.count) # nested lock 2 >>> lock.locked() True >>> lock.release() >>> lock.locked() False
New in version 6.2.

Bases:
collections.abc.Container
,collections.abc.Iterable
,collections.abc.Sized
Structure to hold values where the key is given by the value itself.
A structure like a defaultdict but the key is given by the value itself and cannot be assigned directly. It returns the number of all items with len() but not the number of keys.
Samples:
>>> from pywikibot.tools import SizedKeyCollection >>> data = SizedKeyCollection('title') >>> data.append('foo') >>> data.append('bar') >>> data.append('Foo') >>> list(data) ['foo', 'Foo', 'bar'] >>> len(data) 3 >>> 'Foo' in data True >>> 'foo' in data False >>> data['Foo'] ['foo', 'Foo'] >>> list(data.keys()) ['Foo', 'Bar'] >>> data.remove_key('Foo') >>> list(data) ['bar'] >>> data.clear() >>> list(data) []
New in version 6.1.

None
- class pywikibot.tools.ThreadList(limit=128, wait_time=2, *args)[source]¶
Bases:
list
A simple threadpool class to limit the number of simultaneous threads.
Any threading.Thread object can be added to the pool using the append() method. If the maximum number of simultaneous threads has not been reached, the Thread object will be started immediately; if not, the append() call will block until the thread is able to start.
>>> pool = ThreadList(limit=10) >>> def work(): ... time.sleep(1) ... >>> for x in range(20): ... pool.append(threading.Thread(target=work)) ...
- Parameters
limit (int) – the number of simultaneous threads

- class pywikibot.tools.ThreadedGenerator(group=None, target=None, name='GeneratorThread', args=(), kwargs=None, qsize=65536)[source]¶
Bases:
threading.Thread
Look-ahead generator class.
Runs a generator in a separate thread and queues the results; can be called like a regular generator.
Subclasses should override self.generator, not self.run
Important: the generator thread will stop itself if the generator’s internal queue is exhausted; but, if the calling program does not use all the generated values, it must call the generator’s stop() method to stop the background thread. Example usage:
>>> gen = ThreadedGenerator(target=range, args=(20,)) >>> try: ... data = list(gen) ... finally: ... gen.stop() >>> data [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]
..versionadded:: 3.0
Initializer. Takes same keyword arguments as threading.Thread.
target must be a generator function (or other callable that returns an iterable object).
- Parameters
qsize (int) – The size of the lookahead queue. The larger the qsize, the more values will be computed in advance of use (which can eat up memory and processor time).
name (str) –
- Return type
None
- class pywikibot.tools.Version(version)[source]¶
Bases:
pkg_resources.extern.packaging.version.Version
Version from pkg_resouce vendor package.
This Version provides propreties of vendor package 20.4 shipped with setuptools 49.4.0.
New in version 6.4.
- pywikibot.tools.cached(*arg)[source]¶
Decorator to cache information of an object.
The wrapper adds an attribute to the instance which holds the result of the decorated method. The attribute’s name is the method name with preleading underscore.
Usage:
@cached def this_method(self) @cached def that_method(self, force=False)
No parameter may be used with this decorator. Only a force parameter may be used with the decorated method. All other parameters are discarded and lead to a TypeError.
Note
A property must be decorated on top of the property method below other decorators. This decorator must not be used with functions.
New in version 7.3.
- Raises
TypeError – decorator must be used without arguments
- Parameters
arg (Callable) –
- Return type
Any
- class pywikibot.tools.classproperty(cls_method)[source]¶
Bases:
object
Descriptor class to access a class method as a property.
This class may be used as a decorator:
class Foo: _bar = 'baz' # a class property @classproperty def bar(cls): # a class property method return cls._bar
Foo.bar gives ‘baz’.
New in version 3.0.
Hold the class method.
- Return type
None
- pywikibot.tools.compute_file_hash(filename, sha='sha1', bytes_to_read=None)[source]¶
Compute file hash.
Result is expressed as hexdigest().
- Parameters
filename (str) – filename path
sha (str) – hashing function among the following in hashlib: md5(), sha1(), sha224(), sha256(), sha384(), and sha512() function name shall be passed as string, e.g. ‘sha1’.
bytes_to_read (None or int) – only the first bytes_to_read will be considered; if file size is smaller, the whole file will be considered.
- pywikibot.tools.file_mode_checker(filename, mode=384, quiet=False, create=False)[source]¶
Check file mode and update it, if needed.
- Parameters
filename (str) – filename path
mode (int) – requested file mode
quiet (bool) – warn about file mode change if False.
create (bool) – create the file if it does not exist already
- Raises
IOError – The file does not exist and
create
is False.
- pywikibot.tools.filter_unique(iterable, container=None, key=None, add=None)[source]¶
Yield unique items from an iterable, omitting duplicates.
By default, to provide uniqueness, it puts the generated items into a set created as a local variable. It only yields items which are not already present in the local set.
For large collections, this is not memory efficient, as a strong reference to every item is kept in a local set which cannot be cleared.
Also, the local set can’t be re-used when chaining unique operations on multiple generators.
To avoid these issues, it is advisable for the caller to provide their own container and set the key parameter to be the function
hash
, or use aweakref
as the key.The container can be any object that supports __contains__. If the container is a set or dict, the method add or __setitem__ will be used automatically. Any other method may be provided explicitly using the add parameter.
Beware that key=id is only useful for cases where id() is not unique.
Note: This is not thread safe.
- Parameters
iterable (collections.abc.Iterable) – the source iterable
container (type) – storage of seen items
key (callable) – function to convert the item to a key
add (callable) – function to add an item to the container

New in version 3.0.
- Return type
Optional[str]
- pywikibot.tools.open_archive(filename, mode='rb', use_extension=True)[source]¶
Open a file and uncompress it if needed.
This function supports bzip2, gzip, 7zip, lzma, and xz as compression containers. It uses the packages available in the standard library for bzip2, gzip, lzma, and xz so they are always available. 7zip is only available when a 7za program is available and only supports reading from it.
The compression is either selected via the magic number or file ending.
New in version 3.0.
- Parameters
filename (str) – The filename.
use_extension (bool) – Use the file extension instead of the magic number to determine the type of compression (default True). Must be True when writing or appending.
mode (str) – The mode in which the file should be opened. It may either be ‘r’, ‘rb’, ‘a’, ‘ab’, ‘w’ or ‘wb’. All modes open the file in binary mode. It defaults to ‘rb’.
- Raises
ValueError – When 7za is not available or the opening mode is unknown or it tries to write a 7z archive.
FileNotFoundError – When the filename doesn’t exist and it tries to read from it or it tries to determine the compression algorithm.
OSError – When it’s not a 7z archive but the file extension is 7z. It is also raised by bz2 when its content is invalid. gzip does not immediately raise that error but only on reading it.
lzma.LZMAError – When error occurs during compression or decompression or when initializing the state with lzma or xz.
ImportError – When file is compressed with bz2 but neither bz2 nor bz2file is importable, or when file is compressed with lzma or xz but lzma is not importable.
- Returns
A file-like object returning the uncompressed data in binary mode.
- Return type
file-like object

tools.deprecate module¶
Module providing deprecation decorators.
Decorator functions without parameters are _invoked_ differently from decorator functions with function syntax. For example, @deprecated causes a different invocation to @deprecated().
The former is invoked with the decorated function as args[0]. The latter is invoked with the decorator arguments as *args & **kwargs, and it must return a callable which will be invoked with the decorated function as args[0].
The follow deprecators may support both syntax, e.g. @deprecated and @deprecated() both work. In order to achieve that, the code inspects args[0] to see if it callable. Therefore, a decorator must not accept only one arg, and that arg be a callable, as it will be detected as a deprecator without any arguments.
Changed in version 6.4: deprecation decorators moved to _deprecate submodule
- class pywikibot.tools._deprecate.ModuleDeprecationWrapper(module)[source]¶
Bases:
module
A wrapper for a module to deprecate classes or variables of it.
Initialise the wrapper.
It will automatically overwrite the module with this instance in
sys.modules
.- Parameters

- Return type
None
- add_deprecated_attr(name, replacement=None, *, replacement_name=None, warning_message=None, since='', future_warning=True)[source]¶
Add the name to the local deprecated names dict.
Changed in version 7.0: `since`parameter must be a release number, not a timestamp.
- Parameters
name (str) – The name of the deprecated class or variable. It may not be already deprecated.
replacement (Optional[Any]) – The replacement value which should be returned instead. If the name is already an attribute of that module this must be None. If None it’ll return the attribute of the module.
replacement_name (Optional[str]) – The name of the new replaced value. Required if
replacement
is not None and it has no __name__ attribute. If it contains a ‘.’, it will be interpreted as a Python dotted object name, and evaluated when the deprecated object is needed.warning_message (Optional[str]) – The warning to display, with positional variables: {0} = module, {1} = attribute name, {2} = replacement.
since (str) – a version string string when the method was deprecated
future_warning (bool) – if True a FutureWarning will be thrown, otherwise it provides a DeprecationWarning
- pywikibot.tools._deprecate.add_decorated_full_name(obj, stacklevel=1)[source]¶

stacklevel (int) – level to use
- Return type
None
- pywikibot.tools._deprecate.add_full_name(obj)[source]¶
A decorator to add __full_name__ to the function being decorated.
This should be done for all decorators used in pywikibot, as any decorator that does not add __full_name__ will prevent other decorators in the same chain from being able to obtain it.
This can be used to monkey-patch decorators in other modules. e.g. <xyz>.foo = add_full_name(<xyz>.foo)
- Parameters
obj (callable) – The function to decorate
- Returns
decorating function
- Return type
function
- pywikibot.tools._deprecate.deprecate_arg(old_arg, new_arg)[source]¶
Decorator to declare old_arg deprecated and replace it with new_arg.

@deprecate_arg(‘foo’, ‘bar’) def my_function(bar=’baz’): pass # replaces ‘foo’ keyword by ‘bar’ used by my_function
@deprecare_arg(‘foo’, None) def my_function(): pass # ignores ‘foo’ keyword no longer used by my_function
deprecated_args decorator should be used in favour of this deprecate_arg decorator but it is held to deprecate args which become a reserved word in future Python releases and to prevent syntax errors.
- Parameters
old_arg (str) – old keyword
new_arg (str or None or bool) – new keyword
- pywikibot.tools._deprecate.deprecated(*outer_args, **outer_kwargs)[source]¶
Outer wrapper.
The outer wrapper may be the replacement function if the decorated decorator was called without arguments, or the replacement decorator if the decorated decorator was called without arguments.
- Parameters
outer_args – args
outer_kwargs – kwargs
- pywikibot.tools._deprecate.deprecated_args(**arg_pairs)[source]¶

Return a function which can be used to redirect to ‘target’.
It also acts like marking that function deprecated and copies all parameters.
Changed in version 7.0: `since`parameter must be a release number, not a timestamp.
- Parameters
target (callable) – The targeted function which is to be executed.
source_module (Optional[str]) – The module of the old function. If ‘.’ defaults to target_module. If ‘None’ (default) it tries to guess it from the executing function.
target_module (Optional[str]) – The module of the target function. If ‘None’ (default) it tries to get it from the target. Might not work with nested classes.
old_name (Optional[str]) – The old function name. If None it uses the name of the new function.

Any arguments (positional or keyword) which are not present in arg_names are forwarded. For example a call with 3 parameters and the original function requests one and arg_names contain one name will result in an error, because the function got called with 2 parameters.
The decorated function may not use
*args
or**kwargs
.- Parameters
arg_names (iterable; for the most explanatory message it should retain the given order (so not a set for example).) – The names of all arguments.
tools.djvu module¶
Wrapper around djvulibre to access djvu files properties and content.
- class pywikibot.tools.djvu.DjVuFile(file)[source]¶
Bases:
object
Wrapper around djvulibre to access djvu files properties and content.
Perform file existence checks.
Control characters in djvu text-layer are converted for convenience (see http://djvu.sourceforge.net/doc/man/djvused.html for control chars details).
- Parameters
file (str) – filename (including path) to djvu file
- Return type
None
tools.formatter module¶
Module containing various formatting related utilities.
- class pywikibot.tools.formatter.SequenceOutputter(sequence)[source]¶
Bases:
object
A class formatting a list of items.
It is possible to customize the appearance by changing
format_string
which is used bystr.format
withindex
,width
anditem
. Each line is joined by the separator and the complete text is surrounded by the prefix and the suffix. All three are by default a new line. The index starts at 1 and for the width it’s using the width of the sequence’s length written as a decimal number. So a length of 100 will result in a with of 3 and a length of 99 in a width of 2.It is iterating over
self.sequence
to generate the text. That sequence can be any iterator but the result is better when it has an order.Create a new instance with a reference to the sequence.
- Return type
None
- format_string = ' {index:>{width}} - {item}'¶
- property out¶
Create the text with one item on each line.
- prefix = '\n'¶
- separator = '\n'¶
- suffix = '\n'¶
- pywikibot.tools.formatter.color_format(text, *args, **kwargs)[source]¶
Do
str.format
without having to worry about colors.It is automatically adding 03 in front of color fields so it’s unnecessary to add them manually. Any other 03 in the text is disallowed.
You may use a variant {color} by assigning a valid color to a named parameter color.
Deprecated since version 7.2: new color format pattern like <<color>>colored text<<default>> may be used instead.
- Parameters
text (str) – The format template string
- Returns
The formatted string
- Raises
ValueError – Wrong format string or wrong keywords
- Return type
str
tools._logging module¶
Logging tools.
- class pywikibot.tools._logging.LoggingFormatter(fmt=None, datefmt=None, style='%')[source]¶
Bases:
