JSXS
====

[](#jsxs)

Another Javascript compressor, written in PHP.

Test online at

JSXS is in BETA test since 1 april 2009. Its possible the output compressed code not be a comptatible javascript code. Your browser can return a syntax error after the evaluation of it.

Requirement
-----------

[](#requirement)

JSXS requires a minimum of php 5.1.0 . works on all plateforms.

Usage
-----

[](#usage)

See [example file](https://github.com/xxorax/JSXS/blob/master/example.php).

Options
-------

[](#options)

- compatibility : add semi-colons at the end of block (like function, object...) if necessary. Currently, works only if shrink option is actived.
- reduce : removes blank spaces and comments.
- shrink : reduces the names of variables to shorter.
- concatString : all strings concatenated with the operator of addition are merged.

Features
--------

[](#features)

- adding semicolumn if necessary : In javascript language, the end of line can be interpreted as a semicolumn, so your code without blankspace is probably wrong. This feature adds semicolumns for prevent syntax error.
- remove multiple and unused semicolumn : Multiple ending semicolumn, and semicolumn before ending block are removed, except in for statements.
- remove blankspace and endline : simple and usefull.
- reduce variable names : The names of variable in non-global context are reduced to the smallest possible name, with none conflict. It's the same with function names.
- concat string : Two string separated by + can be concatened.

Example
-------

[](#example)

Uncompressed :

```
function test (arg1) {
  var func = function (arg1) {
    return arg1+2;
  }
  return 'your value' + ' : ' + arg1 + func(arg1);
}
```

Compressed :

```
function test(b){var c=function(a){return a+2};return'your value : '+b+c(b)}
```

Result explained:

- removed white space.
- concatened string : 'your value' + ' : ' => 'your value : '.
- reduced variable names : arg1 => b, func => c, arg1 => a.
- removed semicolumn : ...func(arg1); => ...c(b).
- adding semicolumn for compatibility "} return 'your val..." => "};return'your val...".
