git <https://git-scm.com/docs/gitignore#_pattern_format>_.git-scm.com <https://git-scm.com/docs/gitignore#_pattern_format>_WalkBuilder <https://docs.rs/ignore/0.4.18/ignore/struct.WalkBuilder.html>_ , so You can expect things
will get better over timeThere are many rules that influence whether a particular file or directory is skipped. Those rules are documented here. Note that the rules assume a default configuration.
glob overrides are checked. If a path matches a glob override, then matching stops.
ignore files are checked.
After reading (nesting supported) the .gitignore file, You can match files against the parsers match function. If the file should be ignored, it matches.
We also provide an ignore function for shutil.treecopy so it is easy just to copy a directory tree without the files which should be ignored.
A match indicates, that the file should be ignored.
Suppose /home/bitranox/project/.gitignore contains the following:
.. code-block:: python
# /home/bitranox/project/.gitignore
__pycache__/
*.py[cod]
Then:
.. code-block:: python
>>> import igittigitt
>>> parser = igittigitt.IgnoreParser()
>>> parser.parse_rule_file(pathlib.Path('/home/bitranox/project/.gitignore'))
>>> parser.match(pathlib.Path('/home/bitranox/project/main.py'))
False
>>> parser.match(pathlib.Path('/home/bitranox/project/main.pyc'))
True
>>> parser.match(pathlib.Path('/home/bitranox/project/dir/main.pyc'))
True
>>> parser.match(pathlib.Path('/home/bitranox/project/__pycache__'))
True
# copy the tree without the files which should be ignored by .gitignore
>>> shutil.copytree('/home/bitranox/project', '/home/bitranox/project2', ignore=parser.shutil_ignore)
Patterns which a user wants Git to ignore in all situations (e.g., backup or temporary files generated by the user’s editor of choice) can be put in a file, which location is configured via environment variables :
POSIX : Its default value is $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore is used instead.
WINDOWS : Its default value is %XDG_CONFIG_HOME%/git/ignore. If %XDG_CONFIG_HOME% is either not set or empty, %HOME%/.config/git/ignore is used instead. If %HOME% is either not set or empty, %USERPROFILE%/git/ignore is used instead.
The Usage of the default Pattern can be disabled by setting conf_igittigitt.add_default_patterns=False
I couldn't find a good library for doing the above on PyPI. There are
several other libraries, but they don't seem to support all features,
be it the square brackets in *.py[cod] or top-level paths /....
inspired by https://github.com/mherrmann/gitignore_parser but in fact I needed to throw away almost everything, because of serious matching bugs and unmaintainable spaghetti code.
