Javascript/CSS Problems

When Javascript errors occur, or URIs in CSS files are incorrectly rewritten, enable "debug mode" to ease debugging combined files:

1. Set $min_allowDebugFlag = 'true' in min/config.php
2. Append &debug to the Minify URI. E.g. /min/?f=script1.js,script2.js&debug

Comments will be inserted into the output showing you the line number of the original file(s). E.g.:

/* waitFor.jquery.js */

/* 1  */ (function () {
/* 2  */ 	if (window._waitFor$) {
...
/* 10 */ 	}
/* 11 */ })();

;
/* QueryString.js */

/* 1   */ var MrClay = window.MrClay || {};
/* 2   */ 
...

CSS output will be appended with a comment showing how any relative URIs were rewritten. E.g.:

docRoot    : M:\home\foo\www
currentDir : M:\home\foo\www\css

file-relative URI  : typography.css
path prepended     : M:\home\foo\www\css\typography.css
docroot stripped   : \css\typography.css
traversals removed : /css/typography.css

file-relative URI  : ../images/bg.jpg
path prepended     : M:\home\foo\www\css\..\images\bg.jpg
docroot stripped   : \css\..\images\bg.jpg
traversals removed : /images/bg.jpg

400 Bad Request errors

If Minify can't serve a file for some reason, you'll get a 400 Bad Request error.

1. Set $min_errorLogger = true; in min/config.php
2. Install and enable FirePHP.
3. Reload the URL in Firefox and open Firebug's console

Hopefully you'll see the error appear (misspelled "jquery"):

Minify: Path "M:/home/foo/www/js/jqueryy.js" failed realpath()
