unix-style path processing functions

Project description


unix-style path processing functions


My goal was to provide posixpath path processing functions in pure Python (e.g. normpath, join, split, etc) minus any functions that rely on any kind of "filesystem" concept (stat, etc).

Basically, this is a "minimum viable unix path processing framework." Path processing functions are useful for e.g. ML libraries that want to use unix-style paths to refer to model variables.

(Honestly unixpath is kind of pointless. Its functions are copy-pasted from posixpath, so why not just import posixpath and not worry about the extra dependency on unixpath? Answer: because I was curious how Python implemented their unix path processing functions, so I made this library as a learning exercise.)


python3 -m pip install -U unixpath


import unixpath
unixpath.join('a', 'b') # 'a/b'
unixpath.join('a', 'b', '..', 'c') # 'a/b/../c'
unixpath.normpath('a/b/../c') # 'a/c'
