Haml syntax highlighting for Zed

[!NOTE] This extension is regularly published (https://zed.dev/extensions?query=haml) and can be installed directly from Zed.

You will likely also want to install the Ruby extension so that Ruby snippets within your HAML templates are correctly highlighted.

Releasing

  1. Create a new commit which updates the version field in extensions.toml and commit it to main
  2. Tag that commit with the new version number (e.g. v0.0.1) 
    git tag v0.0.1
git push origin v0.0.1
  3. Create a new GitHub release (https://github.com/davidcornu/zed-haml/releases/new) for that tag. The automatically-generated release notes should suffice.
  4. In https://github.com/zed-industries/extensions/
    1. Update the version field in extensions.toml under [haml]
    2. Run git submodule update --remote --merge extensions/haml
    3. Make sure the ref returned by git submodule status extensions/haml is the correct tag
    4. Commit the above and open a PR
