/* 9 April 2008. version 1.1
|
||||
*
|
||||
* This is the php version of the Dean Edwards JavaScript's Packer,
|
||||
* Based on :
|
||||
*
|
||||
* ParseMaster, version 1.0.2 (2005-08-19) Copyright 2005, Dean Edwards
|
||||
* a multi-pattern parser.
|
||||
* KNOWN BUG: erroneous behavior when using escapeChar with a replacement
|
||||
* value that is a function
|
||||
*
|
||||
* packer, version 2.0.2 (2005-08-19) Copyright 2004-2005, Dean Edwards
|
||||
*
|

* License: http://creativecommons.org/licenses/LGPL/2.1/
|

*
|
||||
* Ported to PHP by Nicolas Martin.
|
||||
*
|
||||
* ----------------------------------------------------------------------
|
||||
* changelog:
|
||||
* 1.1 : correct a bug, '\0' packed then unpacked becomes '\'.
|
||||
* ----------------------------------------------------------------------
|
||||
*
|
||||
* examples of usage :
|
||||
* $myPacker = new JavaScriptPacker($script, 62, true, false);
|
||||
* $packed = $myPacker->pack();
|
||||
*
|
||||
* or
|
||||
*
|
||||
* $myPacker = new JavaScriptPacker($script, 'Normal', true, false);
|
||||
* $packed = $myPacker->pack();
|
||||
*
|
||||
* or (default values)
|
||||
*
|
||||
* $myPacker = new JavaScriptPacker($script);
|
||||
* $packed = $myPacker->pack();
|
||||
*
|
||||
*
|
||||
* params of the constructor :
|
||||
* $script: the JavaScript to pack, string.
|
||||
* $encoding: level of encoding, int or string :
|
||||
* 0,10,62,95 or 'None', 'Numeric', 'Normal', 'High ASCII'.
|
||||
* default: 62.
|
||||
* $fastDecode: include the fast decoder in the packed result, boolean.
|
||||
* default : true.
|
||||
* $specialChars: if you are flagged your private and local variables
|
||||
* in the script, boolean.
|
||||
* default: false.
|
||||
*
|
||||
* The pack() method return the compressed JavasScript, as a string.
|
||||
*
|
||||
* see http://dean.edwards.name/packer/usage/ for more information.
|
||||
*
|
||||
* Notes :
|
||||
* # need PHP 5 . Tested with PHP 5.1.2, 5.1.3, 5.1.4, 5.2.3
|
||||
*
|
||||
* # The packed result may be different than with the Dean Edwards
|
||||
* version, but with the same length. The reason is that the PHP
|
||||
* function usort to sort array don't necessarily preserve the
|
||||
* original order of two equal member. The Javascript sort function
|
||||
* in fact preserve this order (but that's not require by the
|
||||
* ECMAScript standard). So the encoded keywords order can be
|
||||
* different in the two results.
|
||||
*
|
||||
* # Be careful with the 'High ASCII' Level encoding if you use
|
||||
* UTF-8 in your files...
