Relevant Rules

gazelle python BUILD file generator.

Description

I have a repo organized as follows:

• a
  • b
    • d
      • e.py
  • c.py
  • f.py
  • m
    • n.py
    • o.py
    • p.py

I'd like to generate BUILD files that have an individual py_library for each python file. As I understand it, the existing package generation mode will make py_librarys for //a:a, //a:b, //a/b:d, and //a:m in the example above.

Instead, I'd like a file generation mode that makes py_librarys for //a:c, //a/b/d:e, //a:f, //a/m:n, //a/m:o, //a/m:p. This would let me preserve the existing repo structure and file imports in different files (from a.b.d import e).

Describe the solution you'd like

See above.

With enough pointers I could potentially take on the modifications, but wondering if there's reasons this isn't implemented.

Describe alternatives you've considered

I could reorganize my imports to match what the existing package rules expect. However, that would be a huge undertaking and break our existing Pants BUILD rules.
