%TOC\{depth="4"\}% %STARTINCLUDE% # 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. ## TWiki Editing Shorthand
Formatting Command: Example: You write: You get:
Paragraphs:
Blank lines will create new paragraphs.
1st paragraph

2nd paragraph
1st paragraph

2nd paragraph

Headings:
At least three dashes at the beginning of a line, followed by plus signs and the heading text. One plus creates a level 1 heading (most important), two pluses a level 2 heading; the maximum is level 6. Note: A Table of Content can be created automatically with the %TOC% variable, see TWiki Variables?.

Bold Text:
Words get bold by enclosing them in * asterisks.
*Bold*

Italic Text:
Words get italic by enclosing them in _ underscores.
_Italic_

Bold Italic:

Fixed Font:
Words get shown in fixed font by enclosing them in = equal signs.
=Fixed font=
Fixed font
Bold Fixed Font:
Words get shown in bold fixed font by enclosing them in double equal signs.
==Bold fixed==
Bold fixed
Note: Make sure to "stick" the * _ = == signs to the words, e.g. take away spaces.
_This works_,
_this not _
This works, _this not _
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>
class CatAnimal {
  void purr() {
    <code here>
  }
}
</verbatim>
class CatAnimal {
  void purr() {
    <code here>
  }
}
Separator:
At least three dashes at the beginning of a line.

List Item:
Three spaces and an asterisk.

Nested List Item:
Six, nine, ... spaces and an asterisk.
      * nested stuff
    • nested stuff
Ordered List:
Three spaces and a number.
   1 Sushi
   1 Dim Sum
  1. Sushi
  2. Dim Sum
Definition List:
Three spaces, the term, a colon, a space, followed by the definition.
Note: Terms with spaces are not supported. In case you do have a term with more then one word, separate the words with dashes or with the   non-breaking-space entity.
   Sushi: Japan
   Dim Sum: S.F.

Dim Sum

Table:
Optional spaces followed by the cells enclosed in vertical bars.
Note: | *bold* | cells are rendered as table headers.
Note: |   spaced   | cells are rendered center aligned.
Note: |     spaced | cells are rendered right aligned.
Note: | 2 colspan || cells are rendered as multi-span columns.
Note: In case you have a long row and you want it to be more readable when you edit the table you can split the row into lines that end with a '\' backslash character.
| *L* | *C* | *R* |
| A2 |  2  |  2 |
| A3 |  3  |  3 |
| multi span |||
| A4 \
  | next \
  | next |
L C R
A2 2 2
A3 3 3
multi span
A4 next next
WikiWord Links:
CapitalizedWordsStuckTogether (or Wiki Words?) will produce a link automatically.
Note: In case you want to link to a topic in a different %WIKITOOLNAME% web write Webname.TopicName.
WebNotify

Know.ReadmeFirst
Web Notify?

Readme First?

#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 Text Formatting FAQ?. You can also refer to a different web and use anchors.
[[wiki syntax]]

[[%MAINWEB%.TWiki users]]
wiki syntax?

%MAINWEB%.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. Wiki Syntax?) 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 %WIKITOOLNAME% 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 Wiki Word?. 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
Web Home#Not There?

Jump

To here

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

## Using HTML You can use just about any HTML tag without a problem - however, to keep in mind: * On collaboration pages, it's preferable NOT to use HTML, and to use TWiki shorthand instead - this keeps the text uncluttered and easy to edit. * **_NOTE:_** TWiki converts shorthand notation to XHTML 1.0 for display. To copy a fully marked-up page, simply view source in your browser and save the contents. * **_NOTE:_** The standard installation TWiki is compatible across a wide range of browsers and computer platforms. If this is important to you, remember that using browser-specific tags or any other mark-up that doesn't degrade well will reduce compatibility. ## Hyperlinks Being able to create links without any formatting required is a core TWiki feature, made possible with [[WikiWords]]. New TWiki linking rules are a simple extension of the syntax that provide a new set of flexible options. ### Internal Links * [[GoodStyle]] is a [[WikiWord]] that links to the GoodStyle topic located in the current %WIKITOOLNAME% web. * [[NotExistingYet]] is a topic waiting to be written. Create the topic by clicking on the **?**. (Try clicking, but then, **Cancel** - creating the topic would wreck this example!) ### External Links * `http://...`, `https://...`, `ftp://...` and `mailto:...@...` are linked automatically. * Email addresses like `name@domain.com` are linked automatically. * [[Square bracket rules]] let you easily create non-WikiWord links. ## 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 **%WEB%**. * %TOPIC% : The current topic name, is **%TOPIC%**. * %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 %WIKITOOLNAME% web is the default web. Example: **%INCLUDE\{"%TWIKIWEB%.TWikiWebsTable"\}%** * There are many more variables, see **[[TWikiVariables]]**. ## 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 `` 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 `'<'` instead of `'<'`, and `'>'` instead of `'>'`.
Example: Type `'prog <filename>'` to get `'prog '`. * **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. `'©'` is the `©` copyright character. You need to escape `'&'` to see it as it is, so write `'&'` instead of `'&'`.
Example: Type `'This & that'` to get `'This & that'`. ## TWiki Plugins Plugins provide additional text formatting capabilities and can extend the functionality of %WIKITOOLNAME% into many other areas. For example, one optional Plugin lets you create a basic spreadsheet in a similar way to tables. Available Plugins are located in the [[TWikiPlugins]] web on TWiki.org. Currently enabled plugins on here: %PLUGINDESCRIPTIONS% Check on current Plugin status and settings for this site in [[TWikiPreferences]]. -- [[MikeMannix]] - 30 Aug 2001
