I’ll share my add-on: the D language brush for SyntaxHighlighter Evolved, the WordPress plugin. Author of “Evolved” recommands that instead of adding unsupported/unofficial brushes into third-party-brushes directory of his plugin, users should write a NEW plugin that they need for themselves.
Btw, here’s the file.
You may download this, upload to your WordPress blog, and activate manually. Feel free to use it 🙂
