zgitignore 0.8.2

Check if a file is ignored by a .zgitignore file, compatible with .gitignore syntax

zgitignore is a small library to check if a file has been excluded by a .zgitignore file (those are compatible with .gitignore / .dockerignore files).

Installation

As simple as it can be via pip:

$ pip install zgitignore

Or direct installation from source:

$ git clone git://github.com/zb3/zgitignore.git
$ cd zgitignore
$ python setup.py install

Usage

import zgitignore

#ZgitIgnore class stores the patterns, optionally takes two parameters: ignore_case and docker
#by default, it is case sensitive to match .gitignore behaviour
#for .dockerignore compatibility, use docker=True
f = zgitignore.ZgitIgnore(['build/', 'dist/', '*egg-info'])

#Patterns ending with / will match folders only:
print('build file ignored?: ', f.is_ignored('build')) #False

#When matching directories, set second parameter to True:
print('build folder ignored?: ', f.is_ignored('build', True)) #True

#It is case sensitive by default:
print('BUILD folder ignored?: ', f.is_ignored('BUILD', True)) #False

#Want it to be case-insensitive? No problem
f = zgitignore.ZgitIgnore(['*pycache*', '*pyc'], True) #second parameter is ignore_case

print('PYCACHE file ignored?', f.is_ignored('PYCACHE')) #True

#You can also add patterns later
ignorefile = zgitignore.ZgitIgnore(ignore_case=True, docker=True) #this is compatible with .dockerignore files

try:
    with open('.gitignore', 'r') as f:
        ignorefile.add_patterns(f.read().splitlines())
except:
    pass

#You can start paths with ./ or not.
#Paths are normalized to match Unix style paths
print('./a/b/c/d/e ignored?', ignorefile.is_ignored('./a/b/c/d/e'))

#But by default, parent directories aren't checked recursively
#To check them, use check_parents=True
f = zgitignore.ZgitIgnore(['build/'])

print('build/test ignored?', f.is_ignored('build/test')) #False
print('build/test ignored when check_parents=True?', f.is_ignored('build/test', check_parents=True)) #True

Format

zgitignore supports format similar to .gitignore file format. Differences are:

• ** works everywhere

  ``aaa**ooo``

  Will match aaapotato2000/beeeee/llllll/sdsdooo

• It can embed custom regex via {}. You can use \} to pass } to regex and \\ to pass \ to regex

  aaa{12(34|56|78)oo(aa|bb|dd)ii}888

  Will match aaa1256oobbii888

  aaa{#[0-9a-f]{3,6\}}888

  Will match aaa#00ffff888
