23 # <a name="TWiki Text Formatting"></a> TWiki Text Formatting
25 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 laid out below - refer back to this page in a pop-up window from the **Edit** screen.

313 ## <a name="Using HTML"></a> Using HTML
315 You can use just about any HTML tag without a problem - however, there are a few usability and technical considerations to keep in mind.
317 ### <a name="HTML and TWiki Usability"></a> HTML and TWiki Usability
319 - On collaboration pages, it's preferable NOT to use HTML, and to use [[TWiki shorthand|Main/WebHome#TWikiShorthand]] instead - this keeps the text uncluttered and easy to edit.
320 - %X% **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.
322 ### <a name="TWiki HTML Rendering"></a> TWiki HTML Rendering
324 - 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.
325 - %T% 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."
326 - %X% **NOTE:** The opening and closing angle brackets - <code>**<...>**</code> - of an HTML tag **_must be on the same line_**, or the tag will be broken.
327 - 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: <code>**a < b**</code>
328 - %T% 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.
330 ## <a name="Hyperlinks"></a> Hyperlinks
332 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.
334 ### <a name="Internal Links"></a> Internal Links
336 - [[GoodStyle]] is a [[WikiWord]] that links to the GoodStyle topic located in the current %WIKITOOLNAME% web.
338 - [[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!)
340 ### <a name="External Links"></a> External Links
342 - `http://...`, `https://...`, `ftp://...`, `gopher://...`, `news://...`, `file://...`, `telnet://...` and `mailto:...@...` are linked automatically.
344 - Email addresses like `name@domain.com` are linked automatically.
346 - `[[Square bracket rules]]` let you easily create [[non-WikiWord links|Main/WebHome#SquareBrackets]].
347 - You can also write `[[http://yahoo.com Yahoo home page]]` as an easier way of doing external links with descriptive text for the link, such as [Yahoo home page](http://yahoo.com/).
349 ## <a name="TWiki Variables"></a> TWiki Variables
351 Variables are names that are enclosed in percent signs `%` that are expanded on the fly.
353 - `%TOC%` : Automatically generates a table of contents based on headings in a topic - see the top of this page for an example.
355 - `%WEB%` : The current web, is **%WEB%**.
357 - `%TOPIC%` : The current topic name, is **%TOPIC%**.
359 - `%ATTACHURL%` : The attachment URL of the current topic. Example usage: If you attach a file to a topic you can refer to it as <code>**%ATTACHURL%/image.gif**</code> to show the URL of the file or the image in your text.
361 - `%INCLUDE{"SomeTopic"}%` : Server side include, includes another topic. The current %WIKITOOLNAME% web is the default web. Example: <code>**%INCLUDE\{"TWiki.SiteMap"\}%**</code>
363 - `%SEARCH{"sushi"}%` : Inline search showing the search result embedded in a topic. [[FormattedSearch]] gives you control over formatting, used to create web-based applications.
365 - [[TWikiPreferences]] defines site-wide variables. Among others:
366 - **Line break:** Write <code><span><font>%BR%</font></span></code> to start a new line.
367 - **Colored text:** Write: <code><span><font> %RED% Red %ENDCOLOR% and %BLUE% blue %ENDCOLOR% colors</font></span></code> to get: %RED% Red %ENDCOLOR% and %BLUE% blue %ENDCOLOR% colors.
368 - **Documentation Graphics:** Write: <code><span><font> %H% Help, %T% Tip, %X% Alert</font></span></code> to get: %H% Help, %T% Tip, %X% Alert. For more info see [[TWikiDocGraphics]].
370 - There are many more variables, see **[[TWikiVariables]]**.
372 - To "escape" a percent sign that would otherwise be interpreted as a variable, add `<nop>` after the first percent sign. Write: <code><span><font> %<nop>SOMEVARIABLE% </font></span></code> to get: %SOMEVARIABLE%.
374 ## <a name="TWikiPlugin Formatting Extension"></a><a name="_TWikiPlugin Formatting Extensio"></a> TWikiPlugin Formatting Extensions
376 Plugins provide additional text formatting capabilities and can extend the functionality of %WIKITOOLNAME% into many other areas. For example, the optional [SpreadSheetPlugin](http://twiki.org/cgi-bin/view/Plugins/SpreadSheetPlugin) lets you create a spreadsheet with the same basic notation used in TWiki tables.
378 Available Plugins are located in the [Plugins](http://twiki.org/cgi-bin/view/Plugins) web on TWiki.org. Currently enabled plugins on this TWiki installation, as listed by `%PLUGINDESCRIPTIONS%`:
380 - [[SpreadSheetPlugin]] <span>(any TWiki, 10197)</span>:
381 - [[CommentPlugin]] <span>(Dakar, 11359)</span>: Allows users to quickly post comments to a page without an edit/preview/save cycle

392 ## <a name="Common Editing Errors"></a> Common Editing Errors
394 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]]:
396 - **Q:** Text enclosed in angle brackets like `<filename>` is not displayed. How can I show it as it is?
397 - **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 `'>'`. <br /> Example: Type `'prog <filename>'` to get `'prog <filename>'`.
399 - **Q:** Why is the `'&'` character sometimes not displayed?
400 - **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 `'&'`. <br /> Example: Type `'This & that'` to get `'This & that'`.
