Help:Code Syntax Highlighting

This Help topic explains how to add highlighting to code markup in your articles.

For more information see: Extension:SyntaxHighlight_GeSHi (Extension Help). Note that this is a "new plugin" and its native syntax differs from that used on the wiki - which we have maintained for backwards compatability.

Inline code

Use {{Icode|your inline code fragment}} to markup up code fragments within the body of text. For example: "Class CActive is the base class of all Active Objects". This maps to the HTML <tt> tag.

Note: Replace the equals (=) and pipe (|) characters with the &#61; and &#124; codes respectively or this will not work.

Code blocks

The wiki allows you to specify code blocks syntax formatted for a large number of programming languages. You can also specify the initial line number of the block (if any) and a line that should be highlighted.

For example

• <code chsarp> your code</code> - markup code as C#
• <code xml 5> your code</code> - markup code as XML and start line numbering from line 5
• <code cpp 6 highlight="3"> your code</code> - markup code as C++, start line numbering from line 6, and highlight the 3^rd line:

  6. int main(int argc,char *argv){

  7.    int d;

  8.    d = argc + 1;

  9. }

Syntax

<code [language] [n] [highlight="linenumber"] >source code here</code>

Parameters

• language: Code for any of the supported languages, including C# (csharp), C++ (cpp), XML (xml), Java (java) - see full list here.
• n: Line number to start with. A non numeric value (ie "n") will start the list at 001. NOTE that the numbering cycles back to 001 for line numbers greater than 1000.
• highlight="linenumber" : Marks the specified linenumber in highlight (line of the code sample, irrespective of "n" value)

The "default syntax" without parameters is the same as the pre tag: <code>

public class MyClass extends SomeOtherClass
{
    public MyClass()
    {
        System.exit(); // surprise, you're dead!
    }
}

Examples

Specify language (java)

<code java>

public class MyClass extends SomeOtherClass
{
    public MyClass()
    {
        System.exit(); // surprise, you're dead!
    }
}

Line numbers

<code cpp 5>

5. int main(int argc,char *argv){

6.    int d;

7.    d = argc + 1;

8. }

Highlighting (with line numbers)

<code cpp 6 highlight="linenumber">

6. int main(int argc,char *argv){

7.    int d;

8.    d = argc + 1;

9. }
