<!-- ==================== MODULE DESCRIPTION ==================== -->
<h1 class="epydoc">Module rcssmin</h1><p class="nomargin-top"><span class="codelink"><a href="rcssmin-pysrc.html">source code</a></span></p>
<p>CSS Minifier.</p>
<p>The minifier is based on the semantics of the <a class="rst-reference external" href="https://github.com/yui/yuicompressor/" target="_top">YUI compressor</a>, which
itself is based on <a class="rst-reference external" href="https://github.com/isaacs/cssmin/" target="_top">the rule list by Isaac Schlueter</a>.</p>
<p>This module is a re-implementation aiming for speed instead of maximum
compression, so it can be used at runtime (rather than during a preprocessing
step). RCSSmin does syntactical compression only (removing spaces, comments
and possibly semicolons). It does not provide semantic compression (like
removing empty blocks, collapsing redundant properties etc). It does, however,
support various CSS hacks (by keeping them working as intended).</p>
<p>Here's a feature list:</p>
<ul class="rst-simple">
<li>Strings are kept, except that escaped newlines are stripped</li>
<li>Space/Comments before the very end or before various characters are
stripped: <tt class="rst-docutils literal"><span class="pre">:{});=>+],!</span></tt> (The colon (<tt class="rst-docutils literal">:</tt>) is a special case, a single
space is kept if it's outside a ruleset.)</li>
<li>Space/Comments at the very beginning or after various characters are
stripped: <tt class="rst-docutils literal"><span class="pre">{}(=:>+[,!</span></tt></li>
<li>Optional space after unicode escapes is kept, resp. replaced by a simple
space</li>
<li>whitespaces inside <tt class="rst-docutils literal">url()</tt> definitions are stripped</li>
<li>Comments starting with an exclamation mark (<tt class="rst-docutils literal">!</tt>) can be kept optionally.</li>
<li>All other comments and/or whitespace characters are replaced by a single
space.</li>
<li>Multiple consecutive semicolons are reduced to one</li>
<li>The last semicolon within a ruleset is stripped</li>
<li>CSS Hacks supported:<ul>
<li>IE7 hack (<tt class="rst-docutils literal"><span class="pre">>/**/</span></tt>)</li>
<li>Mac-IE5 hack (<tt class="rst-docutils literal"><span class="pre">/*\*/.../**/</span></tt>)</li>
<li>The boxmodelhack is supported naturally because it relies on valid CSS2
strings</li>
<li>Between <tt class="rst-docutils literal"><span class="pre">:first-line</span></tt> and the following comma or curly brace a space is
inserted. (apparently it's needed for IE6)</li>
<li>Same for <tt class="rst-docutils literal"><span class="pre">:first-letter</span></tt></li>
</ul>
</li>
</ul>
<p>rcssmin.c is a reimplementation of rcssmin.py in C and improves runtime up to
factor 100 or so (depending on the input). docs/BENCHMARKS in the source
distribution contains the details.</p>
<p>Both python 2 (>= 2.4) and python 3 are supported.</p>
