NOTE: TWiki is designed to work with a wide range of browsers and computer platforms, holding to HTML 3.2 compatibility in the standard installation - adding raw HTML, particularly browser-specific tags (or any other mark-up that doesn't degrade well) will reduce compatibility.
TWiki HTML Rendering
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.
If you need to save HTML frequently, you may want to check out TWiki:Plugins/GenHTMLAddon - it will "generate a directory containing rendered versions of a set of TWiki pages together with any attached files."
NOTE: The opening and closing angle brackets - <...> - of an HTML tag must be on the same line, or the tag will be broken.
This feature allows you to enter an unclosed angle bracket - as a greater than or less than symbol - and have it automatically rendered as if you had entered its HTML character, <, ex: a > b
If you're pasting in preformatted HTML text and notice problems, check the file in a text processor with no text wrap. Also, save without hard line breaks on text wrap, in your HTML editing program.
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 netfrag.org web is the default web. Example: %INCLUDE{"TWiki.TWikiWebsTable"}%
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 '<' instead of '<', and '>' instead of '>'. Example: Type 'prog <filename>' to get 'prog <filename>'.
Q: Why is the '&' character sometimes not displayed?
Plugins provide additional text formatting capabilities and can extend the functionality of netfrag.org into many other areas. For example, the optional SpreadSheetPlugin lets you create a spreadsheet with the same basic notation used in TWiki tables.

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.

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.
Being able to create links without any formatting required is a core TWiki feature, made possible using WikiNames. With the latest version of TWiki linking rules, a simple extension of the syntax provides an new set of flexible linking options.

"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 '<' instead of '<', and '>' instead of '>'. Example: Type 'prog <filename>' to get 'prog <filename>'.
Q: Why is the '&' character sometimes not displayed?
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.
> >
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.
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 TWikiVariables.

Text strings expanded on the fly to display data or system info
Overview
TWikiVariables are text strings - %VARIABLE% - that expand into content whenever a page is opened. Variables are replaced by their actual values: stored data, or system info (like the date, or the current user). There are predefined variables, and Preference variables that you set. You can also define custom variables, with new names and values.
Predefined Variables
Most predefined variables return values that were either defined when TWiki was installed, or taken from server info (like current username, or date and time). Many of the variables let you control how the formatted results appear.
netfrag.org expands the following variables (enclosed in % percent signs):
Variable:
Expanded to:
%WIKIHOMEURL%
The base script URL of netfrag.org, is the link of the Home icon in the upper left corner, is http://TWiki.org/
%SCRIPTURL%
The script URL of netfrag.org, is https://netfrag.org/twiki/bin
%SCRIPTURLPATH%
The path of the script URL of netfrag.org, is /twiki/bin
%SCRIPTSUFFIX%
The script suffix, ex: .pl, .cgi is
%PUBURL%
The public URL of TWiki, is https://netfrag.org/twiki/pub
%PUBURLPATH%
The path of the public URL of netfrag.org, is /twiki/pub
%ATTACHURL%

%ATTACHURLPATH%
The path of the attachment URL of the current topic, is /twiki/pub/TWiki/TWikiVariables
%URLPARAM{"name"}%
Returns the value of a URL parameter. Ex: %URLPARAM{"skin"}% returns print for a .../view/TWiki/TWikiVariables?skin=print URL. Is

Set VARIABLENAME = value
Creating Custom Variables
You can add your own preference variables for an entire site, a single web, or a single topic, using the standard syntax. Whatever you include in your variable will be expanded on display, and treated exactly as if it had been written out. So you can place formatted text, page links, image paths.
Example: Create a custom logo variable
To place a logo anywhere in a web by typing %MYLOGO%, simply define the variable on the web's WebPreferences page. You also have to upload logo.gif - this can be done by attaching a file to LogoTopic (any topic name you choose):
Set MYLOGO = %PUBURL%/%MAINWEB%/LogoTopic/logo.gif
Variables are names enclosed in percent signs that gets expanded on the fly.
%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{"file.ext"}% : Server side include, includes the text of a file. The default directory is the current Wiki web. Example: %INCLUDE{"Know/TopicName.txt"}%
Text strings expanded on the fly to display data or system info
Overview
TWikiVariables are text strings - %VARIABLE% - that expand into content whenever a page is opened. Variables are replaced by their actual values: stored data, or system info (like the date, or the current user). There are predefined variables, and Preference variables that you set. You can also define custom variables, with new names and values.
Predefined Variables
Most predefined variables return values that were either defined when TWiki was installed, or taken from server info (like current username, or date and time). Many of the variables let you control how the formatted results appear.

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.
The TWiki web has the following types of internal links:
GoodStyle is a topic that is part of the current 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!)
ReadmeFirst? is a topic in a different TWiki web. (You write it as Web.TopicName , but it will show up as TopicName )
External links:
http://..., https://..., ftp://... and mailto:...@... are linked automatically.
Email addresses like name@domain.com are linked automatically.
EDITING
CapitalizedWordsWillProduce? a link automatically.
Blank lines will create new paragraphs.
words get bold by enclosing it with * asterisks
words get italic by enclosing it with _ underscores
words get showns in fixed font by enclosing it with = equal signs
NOTE: TWiki is designed to work with a wide range of browsers and computer platforms, holding to HTML 3.2 compatibility in the standard installation - adding raw HTML, particularly browser-specific tags (or any other mark-up that doesn't degrade well) will reduce compatibility.
If you need to save HTML frequently, you may want to check out TWiki:Plugins/GenHTMLAddon - it will "generate a directory containing rendered versions of a set of TWiki pages together with any attached files."
