Preserve compiled file:/ requirement names.

Issue

Compiling requirements.in files with file: requirements that are named, creates .txt output that lacks the names.
This is in contrast to urls which maintain names.

Thus disallowing .txt generated files from being used as constraints files.

Note: this worked in uv 0.1.2

Info

Version - uv 0.5.5 (95cd8b8b3 2024-11-27)
Platform - 24.1.0 Darwin

# file req
foo @ file:./something

# something/setup.py

setup(name='foo', version='0.1')

# something/something/__init__.py

python -m uv pip compile requirements.in -o requirements.txt

I thought pip didn't allow relative paths in file:, but I guess they do?

Yeah 😅. Vendoring this has just been an adventure all around. Excludingfile: in favor of just referencing the relative path produces the same results, but pip-tools outputs an absolute path to the .txt when you do that, so I use file: as a way to stay a bit more cross-compatible just in case other people read my requirements files and try to emulate anything without using uv.

Wow! Thank you Charlie, that was so fast.
