* Remove legacy *main.py* and introduce *pkgmgr* module entry via *python -m pkgmgr* * Add ***main**.py* as the canonical entry point delegating to the CLI * Export *PYTHONPATH=src* in Makefile to ensure reliable imports in dev and CI * Update setup scripts (venv & nix) to use module execution * Refactor all E2E tests to execute the real module entry instead of file paths This aligns pkgmgr with standard Python packaging practices and simplifies testing, setup, and execution across environments. https://chatgpt.com/share/693c9056-716c-800f-b583-fc9245eab2b4

End-to-end tests for the `pkgmgr path` command.
|
|
|
|
We verify two usage patterns:
|
|
|
|
1) pkgmgr path --all
|
|
- Should print the paths of all configured repositories.
|
|
|
|
2) pkgmgr path pkgmgr
|
|
- Should print the path for the repository identified as "pkgmgr".
|
|
|
|
Both tests are considered successful if the command completes without
|
|
raising an exception and exits with code 0 (or no explicit exit code).
