Create filters

Overview

A filter should be placed in alight.filters (you can change path with alight.getFilter), or in scope.$ns for private filters.

Example filter

alight.filters.mylimit = function(exp, cd) {
    var ce = cd.compile(exp);           // compile the input expression
    return function(value) {            // return handler
        var limit = Number(ce() || 5);
        return value.slice(0, limit)
    }
}

Example on jsfiddle

Input arguments

• expression - an input expression
• cd - change detector

The filter should return a handler/function, one instance of filter.
