Classpublic class Minifier
InheritanceMinifier Inheritance Object
Implements Runnable

Provides a script to remove comments and unnecessary whitespaces from ECMAScript strings. You can use this class to minify .eden, .json, .js files.

Constructor Detail
Minifier()Constructor
public function Minifier(input:String, level:uint = 2)

Creates a new JSMinifier instance.

Parameters
input:String — The String source to minify.
 
level:uint (default = 2) — The level of compression :
  • 1 : minimal, keep linefeeds if single
  • 2 : normal, the standard algorithm
  • 3 : agressive, remove any linefeed and doesn't take care of potential missing semicolons (can be regressive)
    • Method Detail
    action()method
    protected function action(d:uint):String

    Do something! What you do is determined by the argument: 1 : Output A. Copy B to A. Get the next B. 2 : Copy B to A. Get the next B. (Delete A). 3 : Get the next B. (Delete B). action treats a string as a single character. Wow! action recognizes a regular expression if it is preceded by ( or , or =.

    Parameters

    d:uint

    Returns
    String
    run()method 
    public function run(... arguments):void

    minify the javascript/ecmascript String input value.

    Parameters

    ... arguments

    Constant Detail
    AGRESSIVEConstant
    public static const AGRESSIVE:uint = 3

    Remove more linefeed than the original algorithm but can be regressive

    MINIMALConstant 
    public static const MINIMAL:uint = 1

    Original algorithm but keep linefeeds if single.

    NORMALConstant 
    public static const NORMAL:uint = 2

    Original algorithm (conservative).
