HTML Purifier Extras The Method Behind The Madness!The extras/ folder in HTML Purifier contains--you guessed it--extra thingsfor HTML Purifier. Specifically, these are two extra libraries calledFSTools and ConfigSchema. They're extra for a reason: you don't need themif you're using HTML Purifier for normal usage: filtering HTML. However,if you're a developer, and would like to test HTML Purifier, or need touse one of HTML Purifier's maintenance scripts, chances are they'll needthese libraries. Who knows: maybe you'll find them useful too!Here are the libraries:FSTools-------Short for File System Tools, this is a poor-man's object-oriented wrapper forthe filesystem. It currently consists of two classes:- FSTools: This is a singleton that contains a manner of useful functions such as recursive glob, directory removal, etc, as well as the ability to call arbitrary native PHP functions through it like $FS->fopen(...). This makes it a lot simpler to mock these filesystem calls for unit testing.- FSTools_File: This object represents a single file, and has almost any method imaginable one would need.Check the files themselves for more information. vim: et sw=4 sts=4
