coc-scssmodules

Deprecation Notice

coc-cssmodules@v1.1.0 has implemented support for parent selectors so this extension is no longer required. It is recommended to use coc-cssmodules instead going forward.

coc-scssmodules

coc.nvim extension for autocompletion and go-to-definition functionality for CSS Modules.

Note: If you have coc-tsserver installed, the go-to-defininition might show a popup instead linking to type definition for *.module.s?css instead. You'll just need to select the .css file for this case since I don't know how to fix it.

Installation

:CocInstall coc-scssmodules

If you are using vim's plugin manager for coc-extensions, here's an example with vim-plug:

Plug 'mlaursen/coc-scssmodules', {'do': 'yarn install && yarn build'}

Configuration

This extension supports two configuration properties:

{
  "cssmodules.camelCase": {
    "type": ["boolean", "string"],
    "enum": [true, false, "dashes"],
    "default": false,
    "description": "Boolean if the suggestions should be converted to camelCase if you use kebab-case in css files. Should also work with sass parent selectors"
  },
  "cssmodules.hintMessage": {
    "type": "string",
    "default": "string (cssmodule)",
    "description": "The hint message to display next to an autocomplete suggestion from a css module"
  }
}

Acknowledgements

This extension is essentially a port of vscode-css-modules-plugin and coc-cssmodules.

Differences with coc-cssmodules (before v1.1.0)

The main reason I created this implementation was to support parent selectors within scss since I still like BEM for describing different states. If parent selectors (&) are not a concern, you should use the "official" coc-cssmodules instead.

Another small difference is that the configuration will be correctly typed when using :CocConfig and show warnings when the camelCase option is valid or invalid. (This could get ported into the "official" module as well though)

Finally, there is another configuration setting that can be used to show hint details when the autocompletion items if you do not like the default value of string (cssmodule).

TODO

Need to look into a way to actually write tests for this. None of the other coc-* extensions have tests right now, so nothing really to reference. I could write some tests for the utils and regexp at least.

Look into overriding/changing the coc-tsserver plugin for go-to-definitions so this one is the "default" so it doesn't require a selection.

Developing

Since I don't know a way to write automated tests yet with coc.nvim, the best way to do this is:

• start the build watcher with yarn build -w
• update your .vimrc to disable/remove the downloaded coc-scssmodules and use a local path with something like vim-plug to open up one of the test files within the test

  Plug '~/path/to/this-repo'
  

• open up one of the test files in test
• open up the log with :CocOpenLog
• use the provided this.logger to log with this.logger.info
• whenever you make a change, run :CocRestart and :CocOpenLog to see changes

It's pretty ugly.
