Usage

Getting started:

>>> import pth
>>> pth  # the module is a function!
<function pth at ...>
>>> p = pth("a.txt")
>>> p
<Path 'a.txt'>
>>> p
<Path 'a.txt'>

API

>>> p = pth('tests')
>>> p
<Path 'tests'>

Joining paths:

>>> p/"a"/"b"/"c"/"d"
<Path 'tests/a/b/c/d'>

>>> p/"/root"

True

>>> p2.isfile
True

>>> p2()
<...'tests/b.txt'...mode...'r'...>

>>> pth('bogus-doesnt-exist')()

Working with files in a .zip:

Iterating though the contents of the zip:

>>> [i for i in z.tree]
[<ZipPath 'tests/test.zip' / '1/'>, <ZipPath 'tests/test.zip' / '1/1.txt'>, <ZipPath 'tests/test.zip' / 'B.TXT'>, <ZipPath 'tests/test.zip' / 'a.txt'>]

>>> [i for i in z.files]
[<ZipPath 'tests/test.zip' / 'B.TXT'>, <ZipPath 'tests/test.zip' / 'a.txt'>]

>>> [i for i in z.dirs]
[<ZipPath 'tests/test.zip' / '1/'>]

Note that there’s this inconsistency with joining absolute paths:

>>> z/pth('/root')
<Path '/root'>

Vs:

>>> z/'/root'
<ZipPath 'tests/test.zip' / '/root'>

TODO: Make this nicer.

>>> pth.ZipPath('tests', '', '')
<Path 'tests'>

>>> pth.ZipPath.from_string('/bogus/path/to/stuff/bla/bla/bla')
<Path '/bogus/path/to/stuff/bla/bla/bla'>

>>> pth.ZipPath.from_string('bogus')
<Path 'bogus'>

>>> pth.ZipPath.from_string('tests/test.zip/bogus/path/to/stuff/bla/bla/bla')
<ZipPath 'tests/test.zip' / 'bogus/path/to/stuff/bla/bla/bla'>

>>> pth.ZipPath.from_string('tests/1/bogus/path/to/stuff/bla/bla/bla')
<Path 'tests/1/bogus/path/to/stuff/bla/bla/bla'>

>>> pth.ZipPath.from_string('tests')
<Path 'tests'>

>>> pth.ZipPath.from_string('tests/bogus')
<Path 'tests/bogus'>

And there’s a temporary path:

>>> t = pth.TempPath()
>>> t
<TempPath '/tmp/...'>

>>> with t:
...     with (t/"booo.txt")('w+') as f:
...         _ = f.write("test")
...     print([i for i in t.tree])
[<Path '/tmp/.../booo.txt'>]

>>> t.exists
False
