The Code Block macro allows you to display source code in your page with syntax highlighting, like the one below:


Add the Code Block Macro

The Macro Browser allows you to view the list of available Confluence macros and to add them to the current page or blog post.


  1. In the Confluence editor, choose  > Other Macros
  2. Find and select the required macro


Speeding up macro entry with autocomplete:

  • Type { and the beginning of the macro name to see a list of suggested macros.


Details are in Keyboard shortcuts, markdown, and autocomplete.




To edit an existing macro


Click the macro placeholder and choose Edit. A macro dialog window will open, where you can edit the parameters of the macro.


You type the code block directly into the macro placeholder in the editor. Note that any white space contained in the placeholder is not manipulated in any way by the Code Block macro. This is to provide the writer with flexibility over code indentation.

Parameters

Parameters are options that you can set to control the content or format of the macro output. Where the parameter name used in Confluence storage format or wikimarkup is different to the label used in the browser, it will be listed below in brackets (example).
