SourceHighlightPlugin

This plugin allows you to have code fragments automatically formatted and highlighted using the GNU source-highlight package.

Syntax Rules

• Just paste the code between %CODE{"syntax"}% and %ENDCODE%. The following indicates the syntax used for the different languages:

Language	Key	Syntax
C++	cpp	%CODE{"cpp"}% ... %ENDCODE%
C	cpp	%CODE{"cpp"}% ... %ENDCODE%
Flex	flex	%CODE{"flex"}% ... %ENDCODE%
Java	java	%CODE{"java"}% ... %ENDCODE%
Perl	perl	%CODE{"perl"}% ... %ENDCODE%
PHP3	php3	%CODE{"php3"}% ... %ENDCODE%
Prolog	prolog	%CODE{"prolog"}% ... %ENDCODE%
Python	python	%CODE{"python"}% ... %ENDCODE%

You can also define a default language and use the shortcut:

%CODE% ... %ENDCODE%

Examples

%CODE{"cpp"}%
   void foo() {
     print("Do stuff.\n");
   }
%ENDCODE%

Plugin Installation Instructions

Note: You do not need to install anything on the browser to use this plugin. The following instructions are for the administrator who installs the plugin on the server where TWiki is running.

• Install the GNU source-highlight package and note its location
• Open /usr/local/shard/source-highlight/html.outlang. Eliminate all <tt> </tt>s. Because in my browser Firefox 3, it results in a blank line ahead of my code.
• Download the ZIP file from the Plugin web (see below)
• Unzip SourceHighlightPlugin.zip in your twiki installation directory. Content:

• To get a smart-looking box around the code fragment, something like the following is needed in the skin's stylesheet. Note that you may need to change the class name if you modify the FORMATCLASS configuration variable above.

.codefragment {
        background : #FFFFCC;
        border : 1px solid #CCCCCC;
        margin-left : 2em;
        margin-right : 2em;
        padding : 4px;
}

• Test if the installation was successful:

%CODE{"java"}% package com.foo.stuff;

import java.util.ArrayList; import java.util.List;

public class Thingy { private List myList;

public Thingy() { myList = new ArrayList (); }

/** * @param count This is the thingy you want. */ public String getThingy( int count ) { return (String)myList.get( count ); } } %ENDCODE%
