Highlight and format source code fragments of various languages


This plugin allows you to have code fragments automatically formatted and highlighted. It uses the Beautifier library (included) written by Mike Jewell.

Syntax Rules

Insert the code between %CODE{"language"}% and %ENDCODE%. The following table indicates the values used for the different languages:

Language Syntax
bash %CODE{"bash"}% ... %ENDCODE%
C++ %CODE{"cpp"}% ... %ENDCODE%
C# %CODE{"csharp"}% ... %ENDCODE%
Corba %CODE{"corba"}% ... %ENDCODE%
CSS %CODE{"css"}% ... %ENDCODE%
HTML %CODE{"html"}% ... %ENDCODE%
IDL %CODE{"idl"}% ... %ENDCODE%
Java %CODE{"java"}% ... %ENDCODE%
JavaScript %CODE{"javascript"}% ... %ENDCODE%
Lua %CODE{"lua"}% ... %ENDCODE%
Makefile %CODE{"makefile"}% ... %ENDCODE%
Perl %CODE{"perl"}% ... %ENDCODE%
PHP3 %CODE{"php3"}% ... %ENDCODE%
PL/SQL %CODE{"plsql"}% ... %ENDCODE%
Python %CODE{"python"}% ... %ENDCODE%
Scheme %CODE{"scheme"}% ... %ENDCODE%
TCL %CODE{"tcl"}% ... %ENDCODE%
Visual Basic %CODE{"vb"}% ... %ENDCODE%
Verilog %CODE{"verilog"}% ... %ENDCODE%
VHDL %CODE{"vhdl"}% ... %ENDCODE%
XML %CODE{"xml"}% ... %ENDCODE%

Additional languages can be added since the Beautifier library is flexible and can support a wide range of language families. Other languages can be added with relative ease by downloading the full PHP dist from and converting the relevant language file from PHP to Perl. Note: The original website is defunct.

Display Customisation

The code fragments are formaated using CSS. To change the look, upload a new version of style.css to this topic.


   void foo() {
     print("Do stuff.\n");
