TWiki Variables
Special text strings expand on the fly to display user data or system info
TWikiVariables are text strings -
%VARIABLE%
or
%VARIABLE{ parameter="value" }%
- that expand into content whenever a topic is rendered for viewing. There are two types of variables:
- Preferences variables: Can be defined and changed by the user
- Predefined variables: Defined by the TWiki system or by Plugins (for example, the SpreadSheetPlugin introduces a
%CALC{}%
variable)
Using Variables
To use a variable type its name. For example,
- type
%T%
to get (a preferences variable)
- type
%TOPIC%
to get TWikiVariables
(a predefined variable)
- type
%CALC{ "$UPPER(Text)" }%
to get TEXT
(a variable defined by Plugin)
Note:
- To leave a variable unexpanded, precede it with an exclamation point, e.g. type
!%TOPIC%
to get %TOPIC%
- Variables are expanded relative to the topic they are used in, not the topic they are defined in
- Type
%ALLVARIABLES%
to get a full listing of all variables defined for a particular topic
Variable Names
Variable names must start with a letter. The following characters can be letters, numbers and the underscore '_'. You can use both upper-case and lower-case letters and you can mix the characteres. E.g.
%MYVAR%
,
%MyVar%
,
%My2ndVar%
, and
%My_Var%
are all valid variable names. Variables are case sensitive.
%MyVAR%
and
%MYVAR%
are not the same variable.
By convention all settings, predefined variables and variables used by plugins are always UPPER-CASE.
Preferences Variables
Unlike predefined variables, preferences variables can be defined by the user in various places.
Setting Preferences Variables
You can set variables in all the following places:
- local site level in TWikiPreferences
- user level in individual user topics in Main web
- web level in WebPreferences of each web
- topic level in topics in webs
- plugin topics (see TWikiPlugins)
- session variables (if sessions are enabled)
Settings at higher-numbered levels override settings of the same variable at lower numbered levels, unless the variable was included in the setting of FINALPREFERENCES at a lower-numbered level, in which case it is locked at the value it has at that level.
The syntax for setting Variables is the same anywhere in TWiki (on its own TWiki bullet line, including nested bullets):
[multiple of 3 spaces] * [space] Set [space] VARIABLENAME [space] = [space] value
Examples:
Spaces between the = sign and the value will be ignored. You can split a value over several lines by indenting following lines with spaces - as long as you don't try to use * as the first character on the following line.
Example:
* Set VARIABLENAME = value starts here
and continues here
Whatever you include in your Variable will be expanded on display, exactly as if it had been entered directly.
Example: Create a custom logo variable
- To place a logo anywhere in a web by typing
%MYLOGO%
, define the Variable on the web's WebPreferences topic, and upload a logo file, ex: mylogo.gif
. You can upload by attaching the file to WebPreferences, or, to avoid clutter, to any other topic in the same web, e.g. LogoTopic
. Sample variable setting in WebPreferences:
-
Set MYLOGO = %PUBURL%/%WEB%/LogoTopic/mylogo.gif
You can also set preferences variables on a topic by clicking the link
Edit topic preference settings
under
More topic actions
. Preferences set in this manner are not visible in the topic text, but take effect nevertheless.
Access Control Variables
These are special types of preferences variables to control access to content.
TWikiAccessControl explains these security settings in detail.
Local values for variables
Certain topics (a users home topic, web site and default preferences topics) have a problem; variables defined in those topics can have two meanings. For example, consider a user topic. A user may want to use a double-height edit box when they are editing their home topic - but
only when editing their home topic. The rest of the time, they want to have a normal edit box. This separation is achieved using
Local
in place of
Set
in the variable definition. For example, if the user sets the following in their home topic:
* Set EDITBOXHEIGHT = 10
* Local EDITBOXHEIGHT = 20
Then when they are editing any other topic, they will get a 10 high edit box. However when they are editing their home topic, they will get a 20 high edit box.
Local
can be used wherever a preference needs to take a different value depending on where the current operation is being performed.
Use this powerful feature with great care!
%ALLVARIABLES%
can be used to get a listing of the values of all variables in their evaluation order, so you can see variable scope if you get confused.
Frequently Used Preferences Variables
The following preferences variables are frequently used. They are defined in
TWikiPreferences#Miscellaneous_Settings:
-
%BR%
- line break
-
%BULLET%
- bullet sign
-
%BB%
- line break and bullet combined
-
%BB2%
- indented line break and bullet
-
%RED% text %ENDCOLOR%
- colored text (also %YELLOW%
, %ORANGE%
, %PINK%

There are additional useful preferences variables defined in
TWikiPreferences, in
Main.TWikiPreferences, and in
WebPreferences of every web.
Predefined Variables
Most predefined variables return values that were either set in the configuration when TWiki was installed, or taken from server info (such as current username, or date and time). Some, like
%SEARCH%
, are powerful and general tools.
- Predefined variables can be overridden by preferences variables
- Plugins may extend the set of predefined variables (see individual Plugins topics for details)
- 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
%INCLUDINGTOPIC%
, %INCLUDE%
, and the mighty %SEARCH%
.

- The language is detected from the user's browser, unless some site/web/user/session-defined setting overrides it:
- If the
LANGUAGE
preference is set, it's used as user's language instead of any language detected from the browser.
- Avoid defining
LANGUAGE
at a non per-user way, so each user can choose his/her preferred language.
- Related: LANGUAGES
LANGUAGES -- list available TWiki languages
- List the languages available (as
PO
files) to TWiki. Those are the languages in which TWiki's user interface is available.
- Syntax:

expands to
Notes:
-

-
%MAKETEXT{"Did you want to [[[_1]][reset [_2]'s password]]?" args="%TWIKIWEB%.ResetPassword,%WIKIUSERNAME%"}%
expands to
Did you want to reset Main.TWikiGuest's password?
- Notes:
- TWiki will translate the
string
to the current user's language only if it has such string in its translation table for that language.
- Amperstands (
&
) followed by one letter (one of a...z, A...Z) (say, X
) in the translatable string will be translated to <span class='twikiAccessKey'>X</span>
. This is used to implement access keys. If you want to write an actual amperstand that stays just before a letter, write two consecutive amperstands (&&
): they will be transformed in just one.
- translatable string starting with underscores (
_
) are reserved. You cannot use translatable phrases starting with an underscore.
- Make sure that the translatable string is constant. Specially, do not include
%VARIABLES%
inside the translatable strings (since they will get expanded before the %MAKETEXT{...}%
itself is handled).
META -- displays meta-data
- Provided mainly for use in templates, this variable generates the parts of the topic view that relate to meta-data (attachments, forms etc.) The
formfield
item is the most likely to be useful to casual users.

recurse="on" | Recurse into subwebs, if subwebs are enabled. | off |
separator=", " | Line separator between hits | Newline "$n" |
- Example:

type="include"
- like %STARTINCLUDE%
... %STOPINCLUDE%
except that you can have as many include blocks as you want (%STARTINCLUDE%
is restricted to only one).

type="templateonly"
- start position of text to be removed when a template topic is used. This is used to embed text that you do not want expanded when a new topic based on the template topic is created. See TWikiTemplates for more information.
- Syntax:
%STARTSECTION{"name"}% ................ %ENDSECTION{"name"}%
- Syntax:
%STARTSECTION{type="include"}% ........ %ENDSECTION{type="include"}%
- Syntax:

TOC -- table of contents of current topic
TOC{"Topic"} -- table of contents
- Table of Contents. Shows a TOC that is generated automatically based on headings of a topic. Headings in WikiSyntax (
"---++ text"
) and HTML ("<h2>text</h2>"
) are taken into account. Any heading text after "!!"
is excluded from the TOC; for example, write "---+!! text"
if you do not want to list a header in the TOC
- Syntax:
%TOC{"SomeTopic" ...}%
- Supported parameters:
Parameter: | Description: | Default: |
"TopicName" | topic name | Current topic |
web="Name" | Name of web | Current web |
depth="2" | Limit depth of headings shown in TOC | 6 |
title="Some text" | Title to appear at top of TOC | none |
- Example:
%TOC{depth="2"}%
- Example:
%TOC{"TWikiDocumentation" web="TWiki" title="Contents:"}%
- Example: see TWiki:Sandbox.TestTopicInclude
- Hint: TOC will generate links to the headings, so when a reader clicks on a heading it will jump straight where that heading is anchored in the text. If you have two headings with exactly the same text, then their anchors will also be identical and they won't be able to jump to them. To make the anchors unique, you can add an invisible HTML comment to the text of the heading. This will be hidden in normal view, but will force the anchors to be different. For example, ---+ Heading <!--5-->.
