<pre class="haskell"><code>print "hello"</code></pre>

will highlight code as haskell source, for that the value of class attribute of pre element is haskell.


a syntax highlighter middleware

note, do not use this on rss feed, i.e.

make a middleware in your hack middleware chain:

none_rss_highlight :: Middleware
none_rss_highlight app = \env -> do
  if env.path_info.ends_with "rss.xml" 
    then app env
    else highlight app env

and use this!


underneath, it’s just highlighting-kate, so grab those css.

Add them to config/theme/blueprint.txt, e.g.

css        = screen, blueprint-wp, highlight/ascetic, hk-kate, custom

also customized in custom, if you want, e.g.

/* highlight */
table.sourceCode {
  border-top: 1px solid #eee;
  padding-top: 20px;
  padding-bottom: 20px;
  margin-bottom: 20px;
  border-bottom:  1px solid #eee;
  border-left: 5px solid #eee;
  border-right: 0;
  width: 530px;

td.lineNumbers { 
  display: none;
