Code syntax highlighter using Google Prettify, supporting the HTML5 recommendation, and caching plugins.
The main reason for the development of this plugin was the lack of options supporting the HTML5 recommendation, where the code snippets should be tagged with
pre followed by
code, and optionally a class starting with
language- and then our language.
You can use the plugin like this:
<pre class="prettyprint"><code class="language-php"> // my code </code></pre>
Also very important is that although this plugin loads different files depending on your configuration, it fully supports caching scripts (W3 Total Cache) to concatenate and compress all the css and js, so the impact in performance will be minimum.
Other languages are supported via an extension (plugin options): CSS, SQL, YAML, Visual Basic, Clojure, Scala, Latek (TeX, LaTeX), WikiText, Erlang, Go, Haskell, Lua, OCAML, SML, F#, Nemerle, Protocol Buffers, CHDL (VHDL), XQ (XQuery), Lisp, Scheme, Dart, Llvm, Mumps, Pascal, R, S, RD, TCL
Four different styles are provided, and they can be previewed in the plugin options. They are modified to make sure they don't clash with any other styles in your theme.
You have also the option to include your custom style.
Plugin options are at Settings > Prettify Code Syntax. Have a look at the Screenshots tab to see how it looks like.
If you don't care too much about the HTML5 recommendation, you can skip the
language- class. The code always gets detected automatically.
It will also work if you only use a
pre tag without the
code tag (but long lines will be wrapped instead of get horizontal scroll), or if you only use a
code tag with the
prettyprint class (but if you don't use
pre your spaces/returns won't be maintained.)
Be careful using the Visual Editor tab when inserting code, as some HTML tags will be modified or removed.
Using a chaching plugin like W3 Total Cache is highly recommended.
