CMarkdownParser is a wrapper of MarkdownExtra_Parser.

CMarkdownParser extends MarkdownExtra_Parser by using Text_Highlighter to highlight code blocks with specific language syntax. In particular, if a code block starts with the following:
[language]
The syntax for the specified language will be used to highlight code block. The languages supported include (case-insensitive): ABAP, CPP, CSS, DIFF, DTD, HTML, JAVA, JAVASCRIPT, MYSQL, PERL, PHP, PYTHON, RUBY, SQL, XML

You can also specify options to be passed to the syntax highlighter. For example:
[php showLineNumbers=1]
which will show line numbers in each line of the code block.

For details about the standard markdown syntax, please check the following:
