Module | Sass::Features |
In: |
lib/sass/features.rb
|
Provides `Sass.has_feature?` which allows for simple feature detection by providing a feature name.
KNOWN_FEATURES | = | Set[*%w( global-variable-shadowing extend-selector-pseudoclass units-level-3 at-error )] |
This is the set of features that can be detected.
When this is updated, the documentation of `feature-exists()` should be updated as well. |
Add a feature to Sass. Plugins can use this to easily expose their availability to end users. Plugins must prefix their feature names with a dash to distinguish them from official features.
@example
Sass.add_feature("-import-globbing") Sass.add_feature("-math-cos")
@param feature_name [String] The case sensitive name of the feature to
to add to Sass. Must begin with a dash.
Check if a feature exists by name. This is used to implement the Sass function `feature-exists($feature)`
@param feature_name [String] The case sensitive name of the feature to
check if it exists in this version of Sass.
@return [Boolean] whether the feature of that name exists.
