pip-compile: args

[hugocarr]

Summary

We would like to make the arguments into pip compile configurable for rules_uv. Specifically:

• --generate-hashes
• --emit-index-url
• --no-strip-extras
• --custom-compile-command

Description of changes

• Updated docs
• Extracted the logic which parses args into pip.bzl.
• In order for this to work correctly, had to use an eval for the uv pip compile command in both pip_compile.sh and pip_compile_test.sh

Risks

There doesn't seem to be a lot of automated testing available using bazel test, so there may be edge cases I've missed. Particularly with the changes to the bash scripts.

Testing

Tested locally by extending the repo BUILD file with

load("//uv:pip.bzl", "pip_compile")

pip_compile(
    name = "generate_requirements_txt",
    generate_hashes = True,
    emit_index_url = False,
    no_strip_extras = False,
    custom_compile_command = "./bin/run_pip_compile",
)

and running bazel run //:generate_requirements_txt

Tested in a much larger private codebase using

git_override(
    module_name = "rules_uv",
    remote = "https://github.com/hugocarr/rules_uv",
    commit = "c479c2dcb9819ef8cfc4501a0660c993ad8ab4ec",
)

and it works as expected for our usecase.
