Options

functions

Type: Object

An object containing functions. The function name will correspond with the object key.

Example:

var color = require('css-color-converter');

require('postcss-functions')({
    functions: {
        darken: function (value, frac) {
           var darken = 1 - parseFloat(frac);
           var rgba = color(value).toRgbaArray();
           var r = rgba[0] * darken;
           var g = rgba[1] * darken;
           var b = rgba[2] * darken;
           return color([r,g,b]).toHexString();
        }
    }
});

.foo {
    /* make 10% darker */
    color: darken(blue, 0.1);
}

glob

Type: string|string[]

Loads files as functions based on one or more glob patterns. The function name will correspond with the file name.

Example:

require('postcss-functions')({
	glob: path.join(__dirname, 'functions', '*.js')
});
