Code in Habari

Using <code>, I can post short code snippets without relying on Github. e.g,

// my first program in C++
#include 
using namespace std;
int main ()
{
  cout << "Hello World!";
  return 0;
}

Habari has two plug-ins that cater especially to code snippets:

google-code-prettify allows syntax highlighting of source code snippets.

code_escape runs htmlspecialchars() on any code blocks in your post.

Whilst in user/plugins, fetch both plug-ins from their subversion repositories:

$ svn checkout http://svn.habariproject.org/habari-extras/plugins/google-code-prettify/trunk google-code-prettify $ svn checkout http://svn.habariproject.org/habari-extras/plugins/code_escape/trunk code_escape

Make the following changes to plugins/code_escape/code_escape.plugin.php:
