# LESS imports from Mediawiki-core
|
||
|
|
|
||
|
|
The following files:
|
||
|
|
|
||
|
|
- mediawiki.mixins
|
||
|
|
- mediawiki.mixins.animation
|
||
|
|
- mediawiki.mixins.less
|
||
|
|
|
||
|
|
are LESS files containing one-line imports that correspond to files in
|
||
|
|
mediawiki-core. This file structure is required to mimick ResourceLoaders
|
||
|
|
LESS module-import behaviour.
|
||
|
|
|
||
|
|
ResourceLoader can resolve LESS modules with file paths like `@import "mediawiki.ui/variables"`.
|
||
|
|
Webpack however, cannot do this easily. The default LESS resolver requires
|
||
|
|
files ending in ".less", and although webpack can create an alias to a
|
||
|
|
module, that alias cannot include a path separator.
|
||
|
|
|
||
|
|
The webpack LESS-loader treats imports that don't begin with a relative or
|
||
|
|
absolute filepath as coming from the current directory (.i.e. "./").
|
||
|
|
However it provides an option to specify a custom module resolution path.
|
||
|
|
That path is set to this folder, and LESS files that can't be resolved by
|
||
|
|
either relative or absolute paths are searched for here.
|
||
|
|
|
||
|
|
Since this custom resolver requires also requires a ".less" extension,
|
||
|
|
files are duplicated so that "mediawiki.mixins" and "mediawiki.mixins.less"
|
||
|
|
can both be resolved.
