TWiki Text Formatting

 Working in TWiki is as easy as typing in text - exactly like email. You don't need to know HTML, though you can use it if you prefer. Links to topics are created automatically when you enter WikiWords. And TWiki shorthand gives you all the power of HTML with a simple coding system that takes no time to learn. It's all layed out below - refer back to this page in a pop-up window from the Edit screen.

#SquareBrackets
 Forced Links:
You can create a forced internal link by enclosing words in double square brackets.
Note: Text within the brackets may contain optional spaces; the topic name is formed by capitalizing the initial letter and by removing the spaces; i.e. [[text formatting FAQ]] links to topic TextFormattingFAQ. You can also refer to a different web and use anchors.

TWiki Variables

Variables are names that are enclosed in percent signs % that are expanded on the fly.

  • %TOC% : Automatically generates a table of contents based on headings in a topic - see the top of this page for an example.

  • %WEB% : The current web, is TWiki.

  • %TOPIC% : The current topic name, is TextFormattingRules.

  • %ATTACHURL% : The attachment URL of the current topic. Example usage: If you attach a file to a topic you can refer to it as %ATTACHURL%/image.gif to show the URL of the file or the image in your text.

  • %INCLUDE{"SomeTopic"}% : Server side include, includes another topic. The current TWiki web is the default web. Example: %INCLUDE{"TWiki.TWikiWebsTable"}%

Common Editing Errors

TWiki formatting rules are fairly simple to use and quick to type. However, there are some things to watch out for, taken from the TextFormattingFAQ:

  • Q: Text enclosed in angle brackets like <filename> is not displayed. How can I show it as it is?
    • A: The '<' and '>' characters have a special meaning in HTML, they define HTML tags. You need to escape them, so write '&lt;' instead of '<', and '&gt;' instead of '>'.
      Example: Type 'prog &lt;filename&gt;' to get 'prog <filename>'.

  • Q: Why is the '&' character sometimes not displayed?
    • A: The '&' character has a special meaning in HTML, it starts a so called character entity, ex: '&copy;' is the © copyright character. You need to escape '&' to see it as it is, so write '&amp;' instead of '&'.
      Example: Type 'This &amp; that' to get 'This & that'.
