pathlab 0.2

An object-oriented path interface to archives, images, remote filesystems, etc

Pathlab provides an object-oriented path interface to archives, images, remote filesystems, etc. It is built upon pathlib and includes built-in support for:

• tar archives

• zip archives

• iso disc images (inc Rock Ridge; exc Joliet and UDF)

• JFrog Artifactory (via requests)

You can also define your own Path subclass with its own accessor.

Installation

Requires Python 3.6+. Use pip:

pip install --user pathlab

Usage

These usage examples are adapted from the pathlib documentation.

Getting a path type:

>>> from pathlab import TarAccessor
>>> TarPath = TarAccessor('project.tgz').TarPath

Listing subdirectories:

>>> root = TarPath('/')
>>> [x for x in root.iterdir() if x.is_dir()]
[TarAccessor('project.tgz').TarPath('/docs')
 TarAccessor('project.tgz').TarPath('/etc'),
 TarAccessor('project.tgz').TarPath('/project')]

Listing Python source files in this directory tree:

>>> list(root.glob('**/*.py'))
[TarAccessor('project.tgz').TarPath('/setup.py'),
 TarAccessor('project.tgz').TarPath('/docs/conf.py'),
 TarAccessor('project.tgz').TarPath('/project/__init__.py')]

Navigating inside a directory tree:

>>> p = TarPath('/etc')
>>> q = p / 'init.d' / 'reboot'
>>> q
TarAccessor('project.tgz').TarPath('/etc/init.d/reboot')
>>> q.resolve()
TarAccessor('project.tgz').TarPath('/etc/rc.d/init.d/halt')

Querying path properties:

>>> q.exists()
True
>>> q.is_dir()
False

Opening a file:

>>> with q.open() as f: f.readline()
...
'#!/bin/bash\n'
