## README

# PostCSS define-function [![Build Status][ci-img]][ci]

[PostCSS] plugin to implement sass @function.

[PostCSS]: https://github.com/postcss/postcss
[ci-img]:  https://travis-ci.org/titancat/postcss-define-function.svg
[ci]:      https://travis-ci.org/titancat/postcss-define-function

```css
@define-function rem($val) {
    @return $val / 640 * 10 * 1rem;
}
@callFn .foo {
    /* Input example */
    height: rem(640);
}
```

```css
.foo {
  /* Output example */
  height: 10rem}
```

**It only supports the basic four mixed operations: `+`、`-`、`*`、`/`. If you want to be able to use more advanced features, you can use [mixins](https://github.com/postcss/postcss-mixins) instead or help me to improve it.**

**Looking forward to your [issues](https://github.com/titancat/postcss-define-function/issues) and [pull requests](https://github.com/titancat/postcss-define-function/pulls)**

## Usage

```js
postcss([ require('postcss-define-function') ])
```

See [PostCSS] docs for examples for your environment.

## Options

Call plugin function to set options:

```js
postcss([ require('postcss-define-function')({ silent: true }) ])
```

### `silent`
Remove unknown callFns and do not throw a error. Default is `false`.

## Test
```js
// basic feature test
npm test
// preview visual test results
npm run testCase
```
