Module tidy::ext_tool_checks

Optional checks for file types other than Rust source

Handles python tool version managment via a virtual environment in build/venv.

Functional outline

1. Run tidy with an extra option: --extra-checks=py,shell, --extra-checks=py:lint, or similar. Optionally provide specific configuration after a double dash (--extra-checks=py -- foo.py)
2. Build configuration based on args/environment:
   • Formatters by default are in check only mode
   • If in CI (TIDY_PRINT_DIFF=1 is set), check and print the diff
   • If --bless is provided, formatters may run
   • Pass any additional config after the --. If no files are specified, use a default.
3. Print the output of the given command. If it fails and TIDY_PRINT_DIFF is set, rerun the tool to print a suggestion diff (for e.g. CI)

  Attempt to create a virtualenv at this path. Cycles through all expected valid python versions to find one that is installed.
• find_with_extension 🔒
  Check git for tracked files matching an extension
• get_or_create_venv 🔒
  Create a virtuaenv at a given path if it doesn’t already exist, or validate the install if it does. Returns the path to that venv’s python executable.

  Run a python command with given arguments. py_path should be a virtualenv.
• shellcheck_runner 🔒
  Check that shellcheck is installed then run it at the given path
• verify_py_version 🔒
  Parse python’s version output (Python x.y.z) and ensure we have a suitable version.
