5 ---# TWiki Variables
6
7 _Special text strings expand on the fly to display user data or system info_
8
9 <nop>TWikiVariables are text strings - =%<nop>VARIABLE%= - that expand into content whenever a page is rendered for viewing. =VARIABLES= are replaced by data, either user-entered or automatically generated by TWiki (like the date, or the current username). There are predefined variables, and Preference variables that you can configure. You can also define custom variables, with new names and values.
10
11 __Notes:__
12 * To leave a variable unexpanded, precede it with an exclamation point, e.g. type =!%<nop>TOPIC%= to get !%TOPIC%.
13 * Variables are expanded relative to the topic they are _used_ in, not the topic they are _defined_ in.
14
15 ---++ Predefined Variables
16
17 Most predefined variables return values that were either set in the ==lib/twiki.cfg== file, when TWiki was installed, or taken from server info (like current username, or date and time). Many of the variables let you format the appearance of the display results.
18
19 * %T% *Take the time to thoroughly read through ALL preference variables.* If you actively configure your site, review variables periodically. They cover a wide range of functions, and it can be easy to miss the one perfect variable for something you have in mind. For example, see ==%<nop>INCLUDINGTOPIC%==, ==%<nop>INCLUDE%==, and the mighty ==%<nop>SEARCH%==.
20
21 This version of TWiki - %WIKIVERSION% - expands the following variables (enclosed in ==%== percent signs):

32 Additional variables are defined in the preferences topics:

35 * user level ( __UL__ ) in individual user topics

202 ---++ Setting Preferences
203
204 * The syntax for Preferences Variables is the same anywhere in TWiki (on its own TWiki bullet line, including nested bullets): <br />[multiple of 3 spaces] * [space] Set [space] VARIABLENAME [space] = [value]<br /> __Examples:__
205 * ==<nop>Set VARIABLENAME = value==
206 * ==<nop>Set VARIABLENAME = value==
207
208 ---++ Creating Custom Variables
209
210 * You can add your own Preference Variables for us across an entire site or a single web, using the standard [[#SettingPrefs][Preferences syntax]]. Whatever you include in your Variable will be expanded on display, exactly as if it had been entered directly. You can place formatted text, page links, image paths.

213 *Example: Create a custom logo variable the <nop>%WEB% web* <br />
214 * To place a logo anywhere in a web by typing ==%<nop>MYLOGO%==, define the Variable on the web's WebPreferences page, and upload a logo file, ex: =mylogo.gif=. You can upload by [[FileAttachment][attaching the file]] to WebPreferences, or, to avoid clutter, to any other topic in the same web, ex: =LogoTopic=:
215 * ==<nop>Set MYLOGO = %<nop>PUBURL%/<nop>TWiki/LogoTopic/mylogo.gif==
