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 TIP (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:
  1. local site 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.

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 VARIABLENAME = value
    • Set VARIABLENAME = 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. 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%, %PURPLE%, %TEAL%, %NAVY%, %BLUE%, %AQUA%, %LIME%, %GREEN%, %OLIVE%, %MAROON%, %BROWN%, %BLACK%, %GRAY%, %SILVER%, %WHITE%)
  • %H% - HELP Help icon
  • %I% - IDEA! Idea icon
  • %M% - MOVED TO... Moved to icon
  • %N% - NEW New icon
  • %P% - REFACTOR Refactor icon
  • %Q% - QUESTION? Question icon
  • %S% - PICK Pick icon
  • %T% - TIP Tip icon
  • %U% - UPDATED Updated icon
  • %X% - ALERT! Alert icon
  • %Y% - DONE Done icon

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.

  • ALERT! Predefined variables can be overridden by preferences variables
  • ALERT! Plugins may extend the set of predefined variables (see individual Plugins topics for details)
  • TIP 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%.

This version of TWiki - TWiki-4.1.2, Sat, 03 Mar 2007, build 13046 - predefines the following variables:

    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

    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.  
    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.

      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).

VOTE{ attributes } -- define a poll in a TWiki topic.

  • The following standard attributes are recognized
    Name Description Example
    id The identifier of the poll. You can have multiple independent votes in the same topic. id="Dining"
    selectN Defines the name of a select vote, where you select one from a ranges of options. N is a number that identifies this item within the poll e.g. select1, select2 etc. You must number all select and stars parameters uniquely and sequentially (e.g. select1 stars2 select3 select1="Drink"
    optionsN Each selectN must have a corresponding optionsN that defines a comma-separated list of the options that can be selected between. options1="Beer,Wine,Milk"
    starsN Defines the name of a rate vote, where you rate something by giving it a number of stars. N is a number that identifies this item within the poll e.g. select1, stars2 etc. You must number all select and stars parameters uniquely and sequentially (e.g. select1 stars2 select3 stars2="Usability"
    widthN Each starsN must have a corresponding widthN. This gives the number of stars to show e.g. width1="5" will show 5 stars. width2="10"
    formatN Defines the format of the results display. See formatting results, below. format="$large"
    chartN Defines the format of a single bar in the results bar chart generated for the corresponding select (for select type only). See formatting results, below. chart="<p>$option $score</p>"
    separator Defines the string to be used to separate each row in the result. separator="<br/>"
    global If set to "off", this makes the id local to this topic (the default). If set to "on" it will be a global poll that can be accessed from many topics. global="on"
    open If set to "off" this is a closed vote. If set to "on" it is open (the default) open="on"
    secret If set to "off", then the database will record who voted. If set to "on", votes are secret (the default) secret="on"
    saveto If set to the name of a topic, the poll results will be appended to the end of that topic. The results are formatted as a TWiki table for easy post-processing. saveto="Main.VoteResults"
    bayesian If set to "on", rating averages will be computed using the Bayesian average of this item against all the other items that have the same item in their stars field. This requires all the participating %VOTEs to be global, or to save their results to the same place using saveto. See http://www.thebroth.com/blog/118/bayesian-rating for more information about Bayesian rating. bayesian="off"
    submit If set to "off", this makes the %VOTE display the results of the vote without prompting for any input. This is useful when - for example - you want to show the results of a global vote, without permitting more voting.
