|

|

|
Transforms:
|
|
|
|
```css
|
|
:local(.continueButton) {
|
|
composes: button from "library/button.css";
|
|
color: green;
|
|
}
|
|
```
|
|
|
|
into:
|
|
|
|
```css
|
|
:import("library/button.css") {
|
|
button: __tmp_487387465fczSDGHSABb;
|
|
}
|
|
:local(.continueButton) {
|
|
composes: __tmp_487387465fczSDGHSABb;
|
|
color: green;
|
|
}
|
|
```
|
|
|
|
## Specification
|
|
|
|
- Only a certain whitelist of properties are inspected. Currently, that whitelist is `['composes']` alone.
|
|
- An extend-import has the following format:
|
|
```
|
|
composes: className [... className] from "path/to/file.css";
|
|
```
|
|
|
|
## Options
|
|
|
|
- `failOnWrongOrder` `bool` generates exception for unpredictable imports order.
|
|
|
|
```css
|
|
.aa {
|
|
composes: b from './b.css';
|
|
composes: c from './c.css';
|
|
}
|
|
|
|
.bb {
|
|
/* "b.css" should be before "c.css" in this case */
|
|
composes: c from './c.css';
|
|
composes: b from './b.css';
|
|
}
|
|
```
|
|
|
|
## Building
|
|
|
|
```
|
|
npm install
|
|
npm test
|
|
```
