How do I...Display syntax highlighting?

No headers

The Deki Wiki syntax extension provides built-in support for highlighting syntax of popular programming languages. This extension is based on the work done by Alex Gorbatchev on the syntaxhighlighter project. To use it:

Enable the syntax extension using these instructions.
Open the affected page in the editor.
Set Style to Formatted.

Figure 1

Enter the content to which you want to apply syntax highlighting.

Figure 2

Select the content, click Transform Content, and choose a language.

Figure 3

Save the page.

Note that it is also possible to use syntax highlighting on file data, rather than page content. To do this, pass the output of web.text to the syntax extension:

To display the formatted contents of an XML file:

{{ syntax.xml(web.text("http://scripts.mindtouch.com/scratch.xml")) }}
