A pragma is a special component of WikiText that provides control over the way the remaining text is parsed.

Pragmas occupy lines that start with \. They can only appear at the start of the text of a tiddler, but blank lines and comments are allowed between them. If a pragma appears in the main body of the text, it is treated as if it was ordinary text.

Introduced in v5.2.6 Pragmas can have preceding optional whitespace characters.

The following pragmas are available:

• Pragma: \define
• Pragma: \function
• Pragma: \import
• Pragma: \parameters
• Pragma: \procedure
• Pragma: \rules
• Pragma: \whitespace
• Pragma: \widget
