### Code blocks

Code can be rendered generically in a block or inline format (depending on if there are new line characters in the text), or you can specify a supported language for enhanced syntax highlighting. Syntax highlighting requires a suitable rendering plugin such as hilite. Supported languages with the hilite plugin include php, css, mysql, sql, abap, diff, html, perl, ruby, vbscript, avrc, dtd, java, xml, cpp, python, javascript, js, json, sh .
If a rendering plugin is not installed or an unsupported language is specified, the output for syntax highlighted code blocks is the same as the block format code tag.
