This plugin provides configurable rules to check scss files for sassdoc comments. It abides by the stylelint developer guide.

private mixins, functions and variables are currently ignored. See Open issues for more information.

npm install --save-dev stylelint-sassdoc

Make sure you already included your stylelint job to package.json

// all scss files
"stylelint": "stylelint "**/*.scss" --config ./your.stylelint.config.js --fix -s scss"

Add stylelint plugin and sassdoc rules to stylelint config

plugins: [
   'stylelint-sassdoc',
   ...
]

rules: {
   'sassdoc/atExample': [true, {
        severity: 'warning', // optional
    }],
    'sassdoc/atName': true,
    'sassdoc/atParameter': true,
    'sassdoc/atReturn': true,
    'sassdoc/commentblock-postercomment': true,
    'sassdoc/poster-comment': true,
    'sassdoc/variable-has-type': true,

Open issues

  • atReturn
    • Fix RegEx for @return to work without whitespace (might be stylelint stringformatter bug)
  • Optimise Utils
    • Merge checkCommentsForReturn/-Name/-Group/-GroupName/-Params/-Example into one function with parameters for the regex(s) and the direction of the search.
  • atParam
    • checking actual name of parameters
  • poster comment
    • description comes before any annotations
    • check for '/// string' between the last '/// @something' and the closing '////' of the poster comment
    • check for multiple poster comments (only 1 allowed)
    • create option for @group-name since it's a custom property
  • private things
    • mixins, functions and variables that start with underscore '_myColor' need to be parsed differently.
      • either check that they aren't commented and throw an error if they are
      • or check that they have @access private
      • CHALLENGE: the first method conflicts in a way with the other rules, checking for parameters and returns etc. Either we need a separate rule for access private, or extend all the other rules for a check of private things.
  • helper to find all "/// @something" to make the next part simpler
  • optional annotations, to complete the plugin
    • alias
    • author
    • content
    • deprecated
    • ignore
    • link
    • output
    • property
    • require
    • see
    • since
    • throw
    • todo
  • performance
    • try to reuse the sourceArray if it's used multiple times
  • testing

Development

IMPORTANT

postCSS does some on-the-fly processing, so a SCSS comment like:

/// my comment

gets output (and compared) like this:

/*/ my comment */

This makes regEx comparisons more difficult. Check out the helper functions adjacentLineIsSCSSComment, nodeToString and getSourceArray for this.
