rework-plugin-function
function() plugin for rework, formerly included in core
Add user-defined CSS functions.
For example create black(0.5) shortcut, to replace
long rgba(0, 0, 0, 0.5).
var rework = require('rework'),
var reworkFunction = require('rework-plugin-function');
var css = rework(css)
.use(reworkFunction({ black: black }))
.toString()
function black(opacity) {
return 'rgba(0, 0, 0, ' + opacity + ')';
}User code will receive CSS arguments and replace user-defined function by returned code.
input {
box-shadow: 0 0 5px black(0.7);
}yields:
input {
box-shadow: 0 0 5px rgba(0, 0, 0, 0.7);
}Nested functions works well too:
var css = rework(css)
.use(reworkFunction({
subtract: function(a, b) { return a - b },
multiply: function(a, b) { return a * b },
divide: function(a, b) { return a / b },
floor: Math.floor
}))
.toString()input {
top: divide(subtract(30, floor(multiply(20, 10))), 2);
}Would yield:
input {
top: -85;
}
