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:

1. Preferences variables: Can be defined and changed by the user
2. 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 a 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:

1. system level in TWiki.TWikiPreferences
2. plugin topics (see TWikiPlugins)
3. local site level in Main.TWikiPreferences
4. user level in individual user topics in Main web
5. web level in WebPreferences of each web
6. topic level in topics in webs
7. 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.

If you are setting a variable and using it in the same topic, note that TWiki reads all the variable settings from the saved version of the topic before it displays anything. This means you can use a variable anywhere in the topic, even if you set it somewhere inconspicuous near the end. But beware: it also means that if you change the setting of a variable you are using in the same topic, preview will show the wrong thing, and you must save the topic to see it correctly.

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:

   * Set VARIABLENAME1 = value
      * Set VARIABLENAME2 = value

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. Use the same * Set VARIABLENAME = value syntax. 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:

• %BB% - line break and bullet combined
• %BB2% - level 2 bullet with line break
• %BB3% - level 3 bullet with line break
• %BB4% - level 4 bullet with line break
• %BR% - line break
• %BULLET% - bullet sign
• %CARET% - caret symbol
• %VBAR% - vertical bar
• %H% - Help icon
• %I% - Idea icon
• %M% - Moved to icon
• %N% - New icon
• %P% - Refactor icon
• %Q% - Question icon
• %S% - Pick icon
• %T% - Tip icon
• %U% - Updated icon
• %X% - Alert icon
• %Y% - Done icon
• %RED% text %ENDCOLOR% - colored text (also %YELLOW%, %ORANGE%, %PINK%, %PURPLE%, %TEAL%, %NAVY%, %BLUE%, %AQUA%, %LIME%, %GREEN%, %OLIVE%, %MAROON%, %BROWN%, %BLACK%, %GRAY%, %SILVER%, %WHITE%)
• %REDBG% text %ENDBG% - colored background (also %YELLOWBG%, %ORANGEBG%, %PINKBG%, %PURPLEBG%, %TEALBG%, %NAVYBG%, %BLUEBG%, %AQUABG%, %LIMEBG%, %GREENBG%, %OLIVEBG%, %MAROONBG%, %BROWNBG%, %BLACKBG%, %GRAYBG%, %SILVERBG%, %WHITEBG%)

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 (except TOPIC and WEB)
• Plugins may extend the set of predefined variables (see individual plugin 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%.

ENCODE{"string"} -- encodes a string to HTML entities

• Encode "special" characters to HTML numeric entities. Encoded characters are:
  • all non-printable ASCII characters below space, except newline ("\n") and linefeed ("\r")
  • HTML special characters "<", ">", "&", single quote (') and double quote (")
  • TWiki special characters "%", "[", "]", "@", "_", "*", "=" and "|"
• Syntax: %ENCODE{"string"}%
• Supported parameters:

  Parameter:	Description:	Default:
  "string"	String to encode	required (can be empty)
  type="url"	Encode special characters for URL parameter use, like a double quote into %22	(this is the default)
  type="quotes"	Escape double quotes with backslashes (\"), does not change other characters. This type does not protect against cross-site scripting.	type="url"
  type="moderate"	Encode special characters into HTML entities for moderate cross-site scripting protection: "<", ">", single quote (') and double quote (") are encoded. Useful to allow TWiki variables in comment boxes.	type="url"
  type="safe"	Encode special characters into HTML entities for cross-site scripting protection: "<", ">", "%", single quote (') and double quote (") are encoded.	type="url"
  type="entity"	Encode special characters into HTML entities, like a double quote into &#034;. Does not encode newline (\n) or linefeed (\r). Useful to encode text properly in HTML input fields.	type="url"
  type="html"	As type="entity" except it also encodes \n and \r	type="url"

• Example: %ENCODE{"spaced name"}% expands to spaced%20name
• Notes:
  • Values of HTML input fields must be entity encoded.
    Example: <input type="text" name="address" value="%ENCODE{ "any text" type="entity" }%" />
  • Double quotes in strings must be escaped when passed into other TWiki variables.
    Example: %SEARCH{ "%ENCODE{ "string with "quotes"" type="quotes" }%" noheader="on" }%
  • Use type="moderate", type="safe" or type="entity" to protect user input from URL parameters and external sources against cross-site scripting (XSS). type="entity" is the safest mode, but some TWiki applications might not work. type="safe" provides a safe middle ground, type="moderate" provides only moderate cross-site scripting protection.

  "http://..."	A full qualified URL, i.e. %INCLUDE{"http://twiki.org:80/index.html"}%. Supported content types are text/html and text/plain. if the URL resolves to an attachment file on the server this will automatically translate to a server-side include.
  pattern="..."	Include a subset of a topic or a web page. Specify a RegularExpression that scans from start ('^') to end and contains the text you want to keep in parenthesis, e.g., pattern="^.*?(from here.*?to here).*". IncludeTopicsAndWebPages has more.	none
  rev="2"	Include a previous topic revision; N/A for URLs	top revision
  raw="on"	When a page is included, normally TWiki will process it, doing the following: 1) Alter relative links to point back to originating host, 2) Remove some basic HTML tags (html, head, body, script) and finally 3) Remove newlines from HTML tags spanning multiple lines. If you prefer to include exactly what is in the source of the originating page set this to on. raw="on" is short for disableremoveheaders="on", disableremovescript="on", disableremovebody="on", disablecompresstags="on" and disablerewriteurls="on".	disabled
  literal="on"	While using the raw option will indeed include the raw content, the included content will still be processed and rendered like regular topic content. To disable parsing of the included content, set the literal option to "on".	disabled
  disableremoveheaders="on"	Bypass stripping headers from included HTML (everything until first </head> tag)	disabled
  disableremovescript="on"	Bypass stripping all <script> tags from included HTML	disabled
  disableremovebody="on"	Bypass stripping the </body> tag and everything around over and below it	disabled
  disablecompresstags="on"	Bypass replacing newlines in HTML tags with spaces. This compression step rewrites unmatched <'s into &lt; entities unless bypassed	disabled
  disablerewriteurls="on"	Bypass rewriting relative URLs into absolute ones	disabled
  warn="off"	Warn if topic include fails: Fail silently (if off); output default warning (if set to on); else, output specific text (use $topic for topic name)	%INCLUDEWARNING% preferences setting
  section="name"	Includes only the specified named section, as defined in the included topic by the STARTSECTION and ENDSECTION variables. Nothing is shown if the named section does not exists. section="" is equivalent to not specifying a section
  PARONE="val 1"   PARTWO="val 2"	Any other parameter will be defined as a variable within the scope of the included topic. The example parameters on the left will result in %PARONE% and %PARTWO% being defined within the included topic.

• Security Considerations:
  • The ability to INCLUDE arbitrary URLs, such as %INCLUDE{"http://www.google.com/"}% is turned off by default. To turn this on, ask your TWiki administrator to enable the {INCLUDE}{AllowURLs} flag in the Security setup section of configure.
  • JavaScript in included web pages is filtered out as a security precaution per default. Disable filtering with raw or disableremovescript parameter.

  • 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.
