Subject: Simplify GitHub Action entrypoint (#2119)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/5316836393682c6ec6a05d69c549d8167f46d8f6

Simplify GitHub Action entrypoint (#2119)

This commit simplifies entrypoint.sh for GitHub Actions by removing
duplication of args and black_args (cf. #1909).

The reason why #1909 uses the input id black_args is to avoid an overlap
with args, but this naming seems redundant. So let me suggest option
and src, which are consistent with CLI. Backward compatibility is
guaranteed; Users can still use black_args as well.

Commit history pre-merge:
* Simplify GitHub Action entrypoint (#1909)
* Fix prettier
* Emit a warning message when `black_args` is used

  This deprecation should be visible in GitHub Action's UI now.
