Add pre-commit hook support for wikilint

[Chocobo1]

Please consider providing a pre-commit hook for wikilint.

pre-commit is a widely popular framework for managing and maintaining multi-language linter and formatter hooks: https://pre-commit.com/

Implementation references:

• Official instructions for adding hooks:
  https://pre-commit.com/#developing-hooks-interactively
  https://pre-commit.com/#node
• See the markdownlint-cli repository as an example of providing a pre-commit hook: https://github.com/igorshubovych/markdownlint-cli#use-with-pre-commit

Thanks in advance!

Could you please elaborate on your request? I think wikilint should already support pre-commit using the entry hook, e.g.,

- repo: local
  hooks:
  - id: wikilint
    name: wikilint
    entry: npx wikilint --strict
    language: system
    files: \.(wiki|wikitext|mediawiki)$

I will add a -- flag to mark the end of options in the next release, which may help improve the entry hook.

Thanks! That could work.

A few observations after doing more research:

• language: system is obsolete.
  Now it is: language: unsupported
• Lack of clean isolation
  Running npx wikilint --strict installs the package to a shared user directory, and the runtime still depends on the host's installed Node.js version. This is less ideal, as pre-commit hooks typically install into a clean, isolated virtual environment to ensure reproducibility across all supported platforms.
  Fortunately, a workaround is available:

  entry: wikilint --strict
  language: node
  additional_dependencies: ['wikilint']

So the final hook would look like this:

- repo: local
  hooks:
  - id: wikilint
    name: wikilint
    entry: wikilint --strict
    language: node
    additional_dependencies: ['wikilint']
    files: \.(mediawiki|wiki|wikitext)$

I think it is worth to document this in the README to help other users!
I think there isn't much else to add for now. Feel free to close the issue afterwards.
