|
A [SCSS] parser for [PostCSS].
|
|||
|
|
|
|||
|
|
**This module does not compile SCSS.** It simply parses mixins as custom
|
|||
|
|
at-rules & variables as properties, so that PostCSS plugins can then transform
|
|||
|
|
SCSS source code alongside CSS.

|
|||
|

|
## Usage
|
|||
|
|
|
|||
|
|
There are two ways to use this parser:
|
|||
|
|
|
|||
|
|
### 1. SCSS Transformations
|
|||
|
|
|
|||
|
|
The main use case of this plugin is to apply PostCSS transformations directly
|
|||
|
|
to SCSS source code.
|
|||
|
|
|
|||
|
|
For example, you can lint SCSS source with [Stylelint]
|
|||
|
|
and linter will automatically fix issues in the source.
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
// postcss.config.js
|
|||
|
|
module.exports = {
|
|||
|
|
syntax: 'postcss-scss',
|
|||
|
|
plugins: {
|
|||
|
|
…
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
[Stylelint]: http://stylelint.io/
|
|||
|
|
|
|||
|
|
|
|||
|
|
### 2. Inline Comments for PostCSS
|
|||
|
|
|
|||
|
|
Also you can use this parser just to add `//` single-line comment
|
|||
|
|
to your PostCSS project (without any Sass):
|
|||
|
|
|
|||
|
|
```scss
|
|||
|
|
:root {
|
|||
|
|
// Main theme color
|
|||
|
|
--color: red;
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Note that you don’t need a special stringifier to handle the output; the default
|
|||
|
|
one will automatically convert single line comments into block comments.
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
// postcss.config.js
|
|||
|
|
module.exports = {
|
|||
|
|
parser: 'postcss-scss',
|
|||
|
|
plugins: {
|
|||
|
|
…
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
If you want Sass behaviour with removing inline comments, you can use
|
|||
|
|
[postcss-strip-inline-comments] plugin.
