It is easy to collaborate; just type your text. You don't need to know HTML at all, though you can use it if you prefer. Links to topics will be created automatically, as long as you follow these simple Text Formatting Rules. TextFormattingFAQ has answers to frequently asked questions about text formatting.

Links

The Collaborative Work Area is a bunch of related links that are editable through your web browser.

RHUL Physics Department TWiki Internal Links

  • GoodStyle is a WikiWord that links to the GoodStyle topic located in the current RHUL Physics Department TWiki web.
  • NotExistingYet is a topic waiting to be written. You could create that topic by clicking on the question mark. (Do not create that topic; you would wreck this example!)

External Links

  • http://..., https://..., ftp://... and mailto:...@... are linked automatically.
  • Email addresses like name@domain.com are linked automatically.

Verbatim Mode:
Surround code excerpts and other formatted text with <verbatim> and </verbatim> tags.
Note: Use <pre> and </pre> tags instead if you want that HTML code is interpreted.
Note: Each tag must be on a line by itself.
<verbatim>

WikiWord Links:
CapitalizedWordsStuckTogether (or WikiWords) will produce a link automatically.
Note: In case you want to link to a topic in a different RHUL Physics Department TWiki web write Webname.TopicName.
WebNotify

Know.ReadmeFirst
WebNotify

ReadmeFirst

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.
[[wiki syntax]]

[[Public.TWiki users]]
wiki syntax

Public.TWiki users

Specific Links:
Create a link where you can specify the link text and the link reference separately, using nested square brackets like [[reference][text]]. Internal link references (i.e. WikiSyntax) and external link references (i.e. http://TWiki.org/) are supported. The same Forced Links rules apply for internal link references. Anchor names can be added as well, like [[WebHome#MyAnchor][go home]] and [[http://www.yahoo.com/#somewhere][Yahoo!]].
[[WikiSyntax][syntax]]

[[http://gnu.org][GNU]]
syntax

GNU

Anchors:
You can define a link reference inside a RHUL Physics Department TWiki topic (called an anchor name) and link to that. To define an anchor write #AnchorName at the beginning of a line. The anchor name must be a WikiWord. To link to an anchor name use the [[MyTopic#MyAnchor]] syntax. You can omit the topic name if you want to link within the same topic.
[[WebHome#NotThere]]

[[#MyAnchor][Jump]]

#MyAnchor To here
WebHome#NotThere

Jump

To here

Prevent a Link:
Prevent a WikiWord from being linked by prepending it with the <nop> tag.
<nop>SunOS
SunOS

Using HTML

Most HTML tags will work, but it's almost always preferable not to use HTML, so that the markup remains easy for everyone to edit.

TWiki Variables

Variables are names that are enclosed in percent signs; they get expanded on the fly.

  • %TOC% : The table of content, is based on headings in a topic.
  • %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 RHUL Physics Department TWiki web is the default web. Example: %INCLUDE{"TWiki.TWikiWebsTable"}%
  • There are many more variables, see TWikiVariables.

"Gotchas" when Editing Text

The formatting rules are fairly simple to use and fast to type. However, there are some things to watch out for:

  • 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, i.e. '&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'.
