fix(tailwindcss): fix TailwindCSS pack not loading when using tailwindcss-rails Ruby Gem

[natematykiewicz]

📑 Description

#912 caused the Tailwind LSP to not work, when using the tailwindcss-rails Ruby gem.

The tailwindcss-rails Ruby gem keeps the config at config/tailwind.config.js, which is not in the new root_dir config.

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Proper usage of opts table rather than setting things up with the config function.

LGTM!

Sorry about that!

This actually made me go look at the docs and it seems custom config location and names are supported: https://tailwindcss.com/docs/configuration#using-a-different-file-name.

We could consider adding a statement to check package.json for a tailwindcss key, and the equivalent for Ruby projects (and others?).

Thoughts? @mehalter @natematykiewicz

No problem. I sort of wish they didn’t change the default location of the config. But I also get it, every other Rails config is in the config directory.

The Ruby gem doesn’t use package.json. It includes a compiled executable and some Ruby config. It actually exists for Rails apps that want to use Tailwind but have no other need for NodeJS.

FWIW, the official Tailwind guides mention this config file.
