Component Classes

PHP5 Component Classes

Class	Functionality
Minify	Combine, process, and serve pieces of content (usually CSS/JS files). Almost all behavior is configurable including request handling (via controllers), HTTP headers & encoding, caching (file/APC/memcached), and compression functions (by default, the classes below)
JSMin	A port of jsmin.c, extended to preserve some multi-line comments and IE conditional comments (since these occasionally have their uses).
Minify_CSS	Uses the two classes below to minify CSS and optionally rewrite URIs.
Minify_CSS_Compressor	Agressively minifies CSS. Includes a thorough test suite to make sure most common hacks and unusual syntaxes are preserved.
Minify_CSS_UriRewriter	In CSS files, rewrites file-relative URIs as root-relative. With test suite
Minify_HTML	Agressively minifies (X)HTML markup. Preserves TEXTAREA/PRE contents, can invoke minifiers on STYLE and SCRIPT blocks, and wraps content in CDATA blocks in XHTML when necessary. Includes test suite.
Minify_YUICompressor	(Experimental) PHP wrapper for invoking the Java-based YUI Compressor
Minify_ImportProcessor	Linearize a CSS/JS file by including content specified by CSS import declarations. In CSS files, relative URIs are fixed. This has a test suite but should be considered "experimental".
HTTP_Encoder	Applies HTTP encoding to content. Can serve content with conditional encoding based on Accept-Encoding headers (parsed according to HTTP spec) and known browser bugs.
HTTP_ConditionalGet	Implements HTTP conditional GETs via a simple, flexible API.
