-# Reproduces the CI "Preparse .sage files" step locally, so `ruff check` sees
-# the same generated *.sage.py files that the pipeline lints. Run this before
-# `ruff check --no-respect-gitignore .` to catch issues that only show up in
-# the generated output.

-# Uses the sage.repl.preparse.preparse_file() Python API directly rather than
-# the `sage --preparse` CLI flag: the conda-forge `sage` binary used in CI is
-# a cut-down entry point that doesn't support `--preparse` (or `--python`) at
-# all, unlike the official sagemath CLI. Whichever `python` on PATH can
-# actually `import sage.repl` is used to run it -- in CI that's the conda
-# env's own `python`; locally (official sage install) it's `sage --python`.
-#
-# The generated files are gitignored; clean them up afterwards with:
-#   git clean -x sage/ playground/
+
+# This script is run in the CI container to preparse all .sage files into .sage.py files
+# and can also be run locally for local linting/testing.
