Path object VC index

Index versioned .py files

Install

pip install lsfiles

Development

poetry install

Usage

The LSFiles instance is a list-like object instantiated with an empty index

>>> from lsfiles import LSFiles
>>> from pathlib import Path
>>>
>>> files = LSFiles()
>>> files
<LSFiles []>

The LSFiles index calls git ls-files and only versioned files are indexed

>>> files.populate()
>>> for path in sorted([p.relative_to(Path.cwd()) for p in files]):
...     print(path)

The LSFiles instance is an index of unique file paths

It’s implementation of extend prevents duplicates

>>> p1 = Path.cwd() / "f1"
>>> p2 = Path.cwd() / "f1"
>>>
>>> files = LSFiles()
>>> files.extend([p1, p2])
>>> sorted([p.relative_to(Path.cwd()) for p in files.reduce()])
[PosixPath('f1')]

Reduce minimizes index to directories and individual files relative to the current working dir

The list value is returned, leaving the instance unaltered

>>> p1 = Path.cwd() / "f1"
>>>
>>> d = Path.cwd() / "dir"
>>> p2 = d / "f2"
>>> p3 = d / "f3"
>>>
>>> files = LSFiles()
>>> files.extend([p1, p2, p3])
>>> sorted(p.relative_to(Path.cwd()) for p in files.reduce())
[PosixPath('dir'), PosixPath('f1')]

Exclusions can be added on instantiation

Exclusions are evaluated by their basename, and does not have to be an absolute path

>>> p1 = Path.cwd() / "docs" / "conf.py"
>>> p2 = Path.cwd() / "lsfiles" / "__init__.py"
>>>
>>> files = LSFiles()
>>> files.populate(f".*\/{p1.name}")
>>>
>>> ps = [str(p) for p in files]
>>>
>>> assert not str(p1) in ps
>>> assert str(p2) in ps
