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)

On this page:

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 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 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
  • %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.

  • ALERT! Predefined variables can be overridden by preferences variables (except TOPIC and WEB)
  • ALERT! Plugins may extend the set of predefined variables (see individual plugin 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%.

ENCODE{string} -- encode a string to URL entities, HTML entities, CSV format, and more

  • Encode "special" characters in a string to HTML numeric entities, URL entities. Also escapes special characters for CSV use and more.
  • Encoded characters:
    • 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). type="url"
    type="entity"
    extra=" $n$r"     		For type="entity" only, use the extra parameter to encode additional characters to HTML numeric entities. Formatting tokens can be used, such as "$n" for newline. Note that type="entity" extra=" $n$r" is equivalent to type="html". type="url"
    extra=""
    type="html" Encode special characters into HTML entities. In addition to type="entity", it also encodes space, \n and \r. Useful to encode text properly in HTML input fields. See equivalent ENTITY. type="url"
    type="json" Escape double quotes and backslashes with backslashes (\" and \\, respectively), escape non-printable characters with hex code \u0000 ... \u001F, does not change other characters. Use this to properly escape text for a JSON string. Example result: This is a string with \"quoted\" and \\backslashed\\ text. type="url"
    type="csv" Escape single quotes and double quotes by repeating them, other characters do not change. Use this to properly escape fields in CSV reports that output comma-separated values, such as "field 1","field 2 with ''single'' and ""double"" quotes". type="url"
    type="search" Special encoding used for SEARCH: Substitute % characters into non-printable characters, so that TWikiVariables are no longer expanded. Also escapes quotes. Used to feed a search string from a URLPARAM into SEARCH without expanding any variables, such as when searching for %BR%. type="url"
    newline="..." Replace a newline with the specified value before encoding.
    Please note that newline="<br/>" does not bring <br/> to the output because < and > are encoded (except with the quotes and csv types). To have <br/> in the output, you need to specify newline="$br". However, newline="$br" does not work in combination with type="url" (the defautl type). This shouldn't be a problem because it's very rare to need to have <br/> encoded in a URL.
    In addition to $br, $n has a special meaning in a newline parameter value - $n results in a newline in the output.
    This parameter is expected to be used in combination with the moderate, safe, entity, or html type. With the other types, it causes unuseful results.     		 
  • Examples:
    • %ENCODE{"spaced name"}% expands to spaced%20name
    • %ENCODE{"spaced name" type="entity" extra=" "}% expands to spaced&#32;name
  • Notes:
    • Values of HTML input fields should be encoded as "html". A shorter %ENTITY{any text}% can be used instead of the more verbose %ENCODE{ "any text" type="html" }%.
      Example: <input type="text" name="address" value="%ENTITY{any text}%" />
    • Double quotes in strings must be escaped when passed into other TWiki variables.
      Example: %SET{ "lunch" value="%ENCODE{ "string with "quotes"" type="quotes" }%" remember="1" }%
    • Use type="moderate", type="safe", type="entity" or type="html" to protect user input from URL parameters and external sources against cross-site scripting (XSS). type="html" 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.

ENDBG -- end background color section

ENDCOLOR -- end colored text

ENDCOLUMNS -- end a responsive multi-column page layout

ENDSECTION{"name"} -- marks the end of a named section within a topic

  • Syntax: %ENDSECTION{"name"}%
  • Syntax: %ENDSECTION{type="include"}%

  • Syntax: %ENDSECTION{type="expandvariables"}%
  • Supported parameter:
    Parameter: Description:
    "name" Name of the section.
    type="..." Type of the section being terminated; supported types "section", "include", "templateonly", "expandvariables"
  • If the STARTSECTION is named, the corresponding ENDSECTION must also be named with the same name. If the STARTSECTION specifies a type, then the corresponding ENDSECTION must also specify the same type. If the section is unnamed, ENDSECTION will match with the nearest unnamed %STARTSECTION% of the same type above it.

ENTITY{string} -- encode a string to HTML entities

  • Encode "special" characters to HTML entities. Useful to encode text properly for HTML input fields.
  • Encoded characters:
    • all non-printable ASCII characters below space, including newline ("\n") and linefeed ("\r")
    • Space
    • HTML special characters "<", ">", "&", single quote (') and double quote (")
    • TWiki special characters "%", "[", "]", "@", "_", "*", "=" and "|"
  • Syntax: %ENTITY{string}%
  • Example: %ENTITY{text with "quotes" and
    newline}%     expands to text&#32;with&#32;&#34;quotes&#34;&#32;and&#10;newline
  • Notes:
    • To protect against cross-site scripting (XSS), always entity encode text intended for HTML input fields. This is especially true if text is received dynamically via URLPARAM or the like.
      Example: <input type="text" name="address" value="%ENTITY{any text}%" />
    • %ENTITY{string}% is roughly equivalent to %ENCODE{ "string" type="html" }%, but the latter cannot handle strings that have double quotes embedded in it.

ENV{"varname"} -- inspect the value of an environment variable

  • Returns the current value of the environment variable in the CGI (Common Gateway Interface) environment. This is the environment that the TWiki scripts run in on the web server.
  • Note: For security reasons, only those variables whose names match the regular expression in {AccessibleENV} in the Security Settings/Miscellaneous section of configure can be displayed. Any other variable will just be shown as an empty string, irrespective of its real value.
  • Example: %ENV{MOD_PERL}% displays as: not set
  • If a variable is undefined (as against being set to the empty string) it will be returned as not set.

FOURCOLUMNS -- responsive four-column page layout

  • Write %FOURCOLUMNS% ...text... %ENDCOLUMNS% to get a page layout with four columns. The layout is responsive, e.g. it automatically adjusts to a lower number of columns (4 => 3 => 2 => 1) depending on the window width or screen width of the device used. The 300 pixels minimum width of a column determines the number of columns shown. Embedded images scale down automatically to the width of the screen if needed.

IF{"condition" ...} -- simple conditionals

INCLUDE{"page"} -- include other topic, attachment, or web page

  • Merges the content of a specified page into the current one before rendering.
  • Syntax: %INCLUDE{"page" ...}%
  • Supported parameters:
    Parameter: Description: Default:
    "SomeTopic" The name of a topic located in the current web, i.e. %INCLUDE{"WebNotify"}%  
    "Web.Topic" A topic in another web, i.e. %INCLUDE{"TWiki.SiteMap"}%  
    "http://..." A full qualified URL, i.e. %INCLUDE{"http://twiki.org:80/index.html"}%. Supported content types are text/html and text/plain by default. See allowanytype.
    IDEA! if the URL resolves to an attachment file on the server this will automatically translate to a server-side include.     		 
    attachment="filename.ext" Include the specified attachment instead of topic text. The attachment content is subject to processing just like when topic text is included. For example, text up to %STARTINCLUDE% is excluded. When including an attachment, you can do without topic specification - %INCLUDE{attachment="filename.ext"}% works, which results in including the attachment of the same topic.  
    allowanytype="on" Suppress the content type checking in including the web page specified by a URL. disabled
    charset="CHARSET" Specify the charset of the included content so that a proper charset conversion happens when it's different from the site charset. Needless to say, this works for a TWiki topic, a topic attachment, and a content specified with a URL. This parameter overrides otherwise specified or implied charset. none
    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
    headingoffset="2" Adjust the level of headings in the included topic. A "2" or "+2" increases the level by two, e.g. a ---+ H1 turns into a ---+++ H3. Positive and negative values are supported. Adjusted min and max levels are H1 and H6, respectively. no adjustment
    hidetoc="on" Remove %TOC% in included content. Useful to show table of contents in individual topics, while suppressing them if included in a big master document. TOC_HIDE_IF_
    INCLUDED     setting
    rev="2" Include a previous topic revision; N/A for URLs top revision
    raw="on" (for HTTP inclusion) When a page is included via HTTP, 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
    raw="on" (for topic or attachment inclusion) When a topic is included, normally TWiki variables in the included topic are expanded in the context of the included topic. If raw="on" is specified, that variable expansion does not happen. You may wonder what's that for and what are the implications, which are found out on IncludeTopicRaw.
    Because of the "in the raw" nature of the parameter, if it's specified, parameters such as encode, headingoffset, hidetoc, newline, nofinalnewline, and section are ignored.     		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
    nofinalnewline="on" Delete the new line at the end of the result if exists disabled
    newline="$br" Convert newlines in textarea to other delimiters. Variable $br expands to <br /> tag, and $n to a newline. Other text is encoded based on encode parameter. no conversion
    encode="html" Encode special characters into HTML entities. If a FORMFIELD is passed into an HTML form field it should be encoded as "html". Additional encodings available: encode="quote", encode="moderate", encode="safe", encode="entity" and encode="url". See ENCODE for details. no encoding
    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
    disablefixlinks="on" Bypass fixing WikiWord links if include is done across webs. Fixing links in included text such as from SomeLink to Otherweb.SomeLink is usually desirable so that links in included text still point to the same target 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  
    PARAMONE="val 1"
    PARAMTWO="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 %PARAMONE% and %PARAMTWO% being defined within the included topic. A default value for a variable can be specified in the included topic in case the corresponding parameter is not specified, such as %PARAMONE{ default="..." }%  
  • 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.
  • Infinite INCLUDE loop prevention:
    • To prevent obvious infinite INCLUDE loop, %INCLUDE{"http://THIS_SERVER/.../THIS_WEB/THIS_TOPIC}% is detected and blocked.
    • If the server has aliases, $TWiki::cfg{UrlHostRegex} should be set so that it matches all possible server names. e.g. 
      $TWiki::cfg{UrlHostRegex} = qr{http://(www\.)?domain\.com};
  • INCLUDE attachment:
    As described above, there are two ways to include an attachment. They are similar, but behave slightly differently.
    • attachment="filename.ext"
      This works in the same manner as ordinary topic text inclusion. %STARTINCLUDE% and %STOPINCLUDE% in the attachment are observed. The section parameter is observed. The variables are expanded in the context of the topic having the attachment. For example, %TOPIC% is expanded to the name of the topic having the attachment.
    • Specifying the URL of an attachment. (e.g. %INCLUDE{%ATTACHURL%/foo.txt}%)
      The attachment content is processed in the same manner as when data is retrieved from another web server. Unless raw="on" is specified, the content of <body>...</body> is extracted, all occurrences of <script>...</script> are removed. Topic context change doesn't happen because in general inclusion via HTTP doesn't cause topic context change.

LANGUAGE -- current user's language

  • Returns the language code for the language used as the current user. This is the language actually used by TWiki Internationalization (e.g. in user interface).
  • 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.
  • Category: AdministrationVariables, SystemInformationVariables
  • 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: %LANGUAGES{...}%
  • Supported parameters:

MAKETEXT -- translate text using TWiki's I18N infrastructure

  • Text in MAKETEXT is translated into another language at page view time if the user activates a language other than the default English language.
  • Syntax: %MAKETEXT{"string" args="..."}%
  • Supported parameters:
    Parameter Description Default
    "text" or string="text" The text to be displayed. none
    args="param1, param2" a comma-separated list of arguments to be interpolated in the string, replacing the [_N] placeholders in it. none
  • Examples:
    • %MAKETEXT{string="Notes:"}%
      expands to
      Notes:
    • %MAKETEXT{"If you have any questions, please contact [_1]." args="%WIKIWEBMASTER%"}%
      expands to
      If you have any questions, please contact 0.
    • %MAKETEXT{"Did you want to ~[~[[_1]~]~[reset [_2]'s password~]~]?" args="%SYSTEMWEB%.ResetPassword, %WIKINAME%"}%
      expands to
      Did you want to reset 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.
    • Ampersands (&) 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.
    • Square brackets ~[ and ~] in the text have a special meaning and need to be escaped using ~[ and ~], respectively.
    • Translatable string starting with underscores (_) are reserved. You must not use translatable phrases starting with an underscore.
    • Make sure that the translatable string is constant. Specially, do not include %VARIABLES% inside the translatable strings - string would not get translated because variables get expanded before the %MAKETEXT{...}% itself is handled.

MAROON -- start maroon colored text

MDREPO -- retrieve data from metadata repository

  • Attention: This variable works only if MetadataRepository is in use. Otherwise, it always returns a zero length string.
  • This retrieves data from the specified metadata repository table.
  • Syntax: %MDREPO{ "table" ...}% (generic form), %MDREPO{ web="..." ...}% (web specific form)
  • Parameters (generic form without web="..." parameter):
    Parameter Description Default
    "..." Specify the table to retrieve This or below is required
    table="..." (Alternative to above) This or above is required
    separator="..." The separator string of records "$n" (new line)
    format="..." Format of one record. It may contain the following items. In addtion, the standard special tokens are handled accordingly.
    Item Description
    $_ or $_() the record ID
    $__ or $__() The record value in the following format:
    FIELD_NAME=FIELD_VALUE FIELD_NAME=FIELD_VALUE ...
    $marker or $marker() Expands to marker for the item matching selection only
    $_FILED_NAME or $_FIELD_NAME() Please be noted that you need to put _ (underscore) in front of a field name. $_FIELD_NAME$ yields the value of the specified field. If the specified field does not exist in the record, it returns the null string ("").
    ?FIELD_NAME?IF_FIELD_HAS_VALUE? If the specified field has value and it's neither 0 nor the null string (""), it's evaluated as IF_FIELD_HAS_VALUE. Otherwise, it's evaluated as the null string. This is like q/.../ in Perl. A non-word character following ?FIELD_NAME becomes the terminator; i.e. you can write: ?FIELD_NAME:IF_TRUE:
    Specifically, the following characters can be used as the delimiter: ! # % ' / : ? @ ^ ` | ~
    = is excluded because it clashes with a parameter specification in a URL (?name=value).
    ?!FIELD_NAME?IF_FIELD_HAS_NO_VALUE? Similar to above but it's opposite. If the field has value, it's evaluated as the null string. Otherwise, it's evaluated as IF_FIELD_HAS_NO_VALUE.
    $question Replaced with ? after the ?FIEL_DNAME and ?!FIELD_ANME constructs are processed.
    		"| $_ | $__ |"
    selection="..." The record ID to be regarded as the selected. It affects how $marker in the format is evaluated. none
    marker="..." Text for $marker in the format if the item matches selection "selected"
    filter="..." The regular expression of record IDs to filter records. Matching is case-insensitive none
    exclude="..." Comma separated list of record IDs to be excluded. You can use regular expression. If you specify Trash\d*, then Trash, Trash1, Trash2, ... are exluded but LightTrash and TrashBag are not excluded none
  • Example: %MDREPO{"webs" filter="^A" format="| $_ | $_admin | $_master |"}%
    This would show the metadata of webs whose names start with A.
  • Paramerers (web specific form):
    Parameter Description Default
    web="..." Specify the web. If it's a subweb, the corresponding top level web is specified This is required
    "..." Specify the format of the return value in the same manner as the format parameter in the generic form $__
    default="..." Specify the value to be returned when the specified or implied top level web does not exist in MDREPO "" (null string)
  • Example: %MDREPO{web="Foo/Bar" "$_admin"}%
    This would show the admin field of the Foo web.

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.
  • Syntax: %META{ "item" ...}%
  • Parameters:
    Item Options Description
    "formfield" name="...": name of the field. The field value can be shortened as described in FormattedSearch for $formfield.
    newline="...": by default, each newline character will be rewritten to <br /> to allow metadata that contains newlines to be used in tables, etc. $n indicates a newline character.
    bar="...": by default, each vertical bar is rewritten to an HTML entity so as to not be mistaken for a table separator.
    encode="type": have the value encoded in the specified type. Possible types are the same as ENCODE's. If this is specified, newline and bar options are ignored.
    topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%".     		Show a single form field
    "form" topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%". Generates the table showing the form fields. See Form Templates
    "attachments" all="on" to show hidden attachments.
    title="..." to show a title - only if attachments are displayed.
    template="..." to use a custom template for the rendering of attachments; default attachtables is used.
    topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%".     		Generates the list of attachments
    "moved" topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%". Details of any topic moves
    "parent" dontrecurse="on": By default recurses up tree, this has some cost.
    nowebhome="on": Suppress WebHome.
    prefix="...": Prefix that goes before parents, but only if there are parents, default "".
    format="...": Format string used to display each parent topic where $web expands to the web name, and $topic expands to the topic name; default: "[[$web.$topic][$topic]]"
    suffix="...": Suffix, only appears if there are parents; default "".
    separator="...": Separator between parents; default " > ".
    topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%".     		Generates the parent link
  • Attention: The base topic, not the current topic, is used if %META{}% is placed in an included topic. Add a topic="%WEB%.%TOPIC%" parameter if you need meta info of the current topic.
  • Note: Formatting tokens can be used for newline, prefix, format, suffix and separator options, such as separator="$n   * "

S -- red star icon

SCRIPTNAME -- name of current script

SCRIPTSUFFIX -- script suffix

SCRIPTURL -- base URL of TWiki scripts

SCRIPTURL{"script"} -- URL of TWiki script

  • Expands to the URL of the specified script. Optionally, you can specify a web and/or a topic. In that case, the URL of the script for the specified web and topic is returned.
  • If ReadOnlyAndMirrorWebs is in effect and a web is specified, whether the web is a slave or not is taken into account. For a slave web, with scripts edit, save, attach, upload, and rename, the URL on the master site is returned.
    For the other scripts, if the master="on" parameter is specified, the URL on the master site is returned.
  • Syntax: %SCRIPTURL{"script" ...}%
  • Supported parameters:
    Parameter: Description: Default:
    "script" The name of the script  
    web="WEB" Specifies a web When a topic name is specified and a web is not, the current web is assumed
    topic="TOPIC" or topic="WEB.TOPIC" Specifies a topic or both a web and a topic  
    master="on" A URL on the master site is needed or not off
  • If web="WEB" is specified but topic is not specified, the resulting URL ends with WEB.
  • Example: To get the authenticated version of the current topic you can write %SCRIPTURL{"viewauth"}%/%WEB%/%TOPIC% which expands to https://twiki.cargooffice.com/bin/viewauth/TWiki/TWikiVariables. It can be written %SCRIPTURL{"viewauth" topic="%TOPIC%"}% as well.
  • Example: Let's assume this site has a web named 'Flowers' whose master site is http://florawiki/cgi-bin. Then %SCRIPTURL{"edit" web="Flowers"}% expands to http://florawiki/cgi-bin/edit/Flowers. This is because the 'Flower' web on this site is a slave and editing needs to happen on the master site.
  • Example: Asuming above, %SCRIPTURL{"view" web="Flowers" master="on"}% expands to http://florawiki/cgi-bin/view/Flowers. The view script works on a slave site, but master="on" parameter forces to yield the master site URL.
  • Example: How to link to another topic with a URL parameter: [[%SCRIPTURL{view}%/%WEB%/MyQuery?food=sushi][Sushi]]
  • Note: In most cases you should use %SCRIPTURLPATH{"script"}% instead, as it works with URL rewriting much better

SCRIPTURLPATH -- base URL path of TWiki scripts

SCRIPTURLPATH{"script"} -- URL path of TWiki script

  • As %SCRIPTURL{"script"}%, but doesn't include the protocol and host part of the URL
  • Like %SCRIPTURL{"script"}%, this variable is aware of ReadOnlyAndMirrorWebs. So it may return a URL of a different site.
  • Syntax: %SCRIPTURLPATH{"script" ...}%
  • Supported parameters:
    Parameter: Description: Default:
    "script" The name of the script.  
    web="WEB" Specifies a web When a topic name is specified and a web is not, the current web is assumed
    topic="TOPIC" or topic="WEB.TOPIC" Specifies a topic or both a web and a topic  
    master="on" A URL on the master site is needed or not. off
  • If web="WEB" is specified but topic is not specified, the resulting URL ends with WEB.
  • Example: %SCRIPTURLPATH{"view"}% expands to "/bin/view" (This might be a null string. Hence surrounded by double quotes)
  • Example: %SCRIPTURLPATH{"view" web="%WEB%"}% expands to /bin/view/TWiki
  • Example: %SCRIPTURLPATH{"view" topic="%TOPIC%"}% expands to /bin/view/TWiki/VarSCRIPTURLPATH2
  • Example: Let's assume this site has a web named 'Flowers' whose master site is http://florawiki/cgi-bin. Then %SCRIPTURLPATH{"edit" web="Flowers"}% expands to http://florawiki/cgi-bin/edit/Flowers. This is because the 'Flower' web on this site is a slave and editing needs to happen on the master site.

    web="Main, Know"
    web="all"     		Comma-separated list of webs to search. You can specifically \*exclude\* webs from an all search using a minus sign - for example, web="all,-Secretweb". The special word all means all webs that do not have the NOSEARCHALL variable set to on in their WebPreferences. Note that TWikiAccessControls are respected when searching webs; it is much better to use them than NOSEARCHALL. Current web
    topic="WebPreferences"
    topic="*Bug"     		Limit search to topics: A topic, a topic with asterisk wildcards, or a list of topics separated by comma. Note this is a list of topic names and must not include web names. All topics in a web
    excludetopic="Web*"
    excludetopic="WebHome, WebChanges"     		Exclude topics from search: A topic, a topic with asterisk wildcards, or a list of topics separated by comma. Note this is a list of topic names and must not include web names. None

    word: identical to keyword but searches whole words: topics with "soapsuds" will not be found, and topics with "shampoos" will not be excluded
    literal: search for the exact string, like web service
    regex: use a RegularExpression search like soap;web service;!shampoo; to search on whole words use \bsoap\b
    query: query search of form fields and other meta-data, like (Firstname='Emma' OR Firstname='John') AND Lastname='Peel'     		%SEARCHVAR- DEFAULTTYPE% preferences setting (literal)
    sort="topic"
    sort="created"
    sort="modified"
    sort="editby"
    sort="parent"
    sort="parent(99)"
    sort="formfield(name)"
    sort="parent,
     formfield(name)"         		Sort the search results by:

    • parent: parent topic name,
    • parent(N): parent breadcrumb up to indicated level,
    • formfield(NAME): named TWikiForms field,
    • or a combination to sort by more than one field using a comma list.
    The sorting is done web by web; if you want to sort across webs, create a formatted table and sort it with TablePlugin's initsort. Note that dates are sorted most recent date last (i.e at the bottom of the table). Legacy order parameter is used in case sort is not specified.     		"topic"
    reverse="on"
    reverse="off, on"     		Reverse the direction of the search. Specify a comma list of on, off tokens to toggle direction by sort field. If sort has more fields than reverse tokens, the state of the last reverse token is taken for the remaining fields. "off"
    start="0"
    start="20"     		Specify the number of results to skip. This is done after sorting if sort parameter is specified. This is intended for pagination of results. If this parameter is specified, %NTOPICS% in the search template is replaced with the number of topics matched. Without this parameter, %NTOPICS% doesn't exceed the limit value. "0"
    limit="all"
    limit="16"     		Limit the number of results returned. This is done after sorting if sort parameter is specified. This parameter specifing the number of results remains the same in the presense of the start parameter. Assuming there are more than 20 results matched, start="10" limit="10" results in 11th to 20th results are returned "all"
    date="..." limits the results to those pages with latest edit time in the given time interval. All results
    createdate="..." similar to date but it's about create time instead of last edit. You can specify both date and createdate, in which case topics matching both conditions are shown. All results

    nosummary="on" Show topic title only Show topic summary
    nosearch="on" Suppress search string Show search string
    noheader="on" Suppress default search header
    Topics: Changed: By: , unless a header is explicitly specified     		Show default search header, unless search is inline and a format is specified (Cairo compatibility)
    nototal="on" Do not show number of topics found Show number
    zeroresults="off" Suppress all output if there are no hits zeroresults="on", displays: "Number of topics: 0"
    noempty="on" Suppress results for webs that have no hits. Show webs with no hits
    headingoffset="2" Adjust the level of headings in text of topics found, taking effect in $text and $pattern() of a FormattedSearch. A "2" or "+2" increases the level by two, e.g. a ---+ H1 turns into a ---+++ H3. Positive and negative values are supported. Adjusted min and max levels are H1 and H6, respectively. no adjustment
    header="..."
    format="..."
    footer="..."     		Custom format results. See FormattedSearch for usage, variables & examples Results in table
    default="..." Default message if there are no hits in a web. See FormattedSearch for usage, variables & examples No output
    expandvariables="on" Expand variables before applying a FormattedSearch on a search hit. Useful to show the expanded text, e.g. to show the result of a SpreadSheetPlugin %CALC{}% instead of the formula Raw text
    multiple="on" Multiple hits per topic. Each hit can be formatted. The last token is used in case of a regular expression ";" and search Only one hit per topic
    nofinalnewline="on" If on, the search variable does not end in a line by itself. Any text continuing immediately after the search variable on the same line will be rendered as part of the table generated by the search, if appropriate. off
    recurse="on" Recurse into subwebs, if subwebs are enabled. off
    separator=", " Line separator between search hits. Specify format="$topic" separator=", " to get a comma separated list of topic names. The following variables can be used in the separator value: $n expands to a newline, $br expands to a <br /> line break tag. "$n" (Newline)
    newline="$br" Line separator within a search hit. Useful if you want to put multi-line content into a table cell, for example if the format="" parameter contains a $pattern() that captures more than one line, or contains a $formfield() that returns a multi-line textfield. The following variables can be used in the newline value: $n expands to a newline, $br expands to a <br /> line break tag. "$n" (Newline)
    encode="html" Encode special characters into HTML entities. If a FORMFIELD is passed into an HTML form field it should be encoded as "html". Additional encodings available: encode="quote", encode="moderate", encode="safe", encode="entity" and encode="url". See ENCODE for details. no encoding
  • Example: %SEARCH{"wiki" web="Main" scope="topic"}%
  • Example with URLPARAM: %SEARCH{"%URLPARAM{"query" encode="search"}%" web="Main"}%
  • Example with format: %SEARCH{"FAQ" scope="topic" nosearch="on" nototal="on" header="| *Topic: * | *Summary: * |" format="| $topic | $summary |"}% (displays results in a table with header - details)
  • HELP Hint: If the TWiki:Plugins.TablePlugin is installed, you may set a %TABLE{}% variable just before the %SEARCH{}% to alter the output of a search. Example: %TABLE{ tablewidth="90%" }%

THREECOLUMNS -- responsive three-column page layout

  • Write %THREECOLUMNS% ...text... %ENDCOLUMNS% to get a page layout with three columns. The layout is responsive, e.g. it automatically adjusts to a lower number of columns (3 => 2 => 1) depending on the window width or screen width of the device used. The 300 pixels minimum width of a column determines the number of columns shown. Embedded images scale down automatically to the width of the screen if needed.
  • Syntax: %THREECOLUMNS% ... %ENDCOLUMNS%
  • Example:
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed viverra ante ac augue sagittis semper. Vestibulum sed urna quam. Phasellus eleifend dolor id dui dictum lobortis. Etiam enim erat, fermentum eget libero non, pretium vestibulum nisi. Nam eget nisi diam. Cras egestas, nibh a malesuada hendrerit, tellus turpis gravida dolor, at fermentum ipsum libero id eros. Mauris a nunc turpis. Fusce turpis dui, blandit nec maximus at, sagittis et arcu. Duis eros sapien, accumsan sed varius eget, elementum eu sapien.

URLPARAM{"name"} -- get value of a URL parameter

  • Returns the value of a URL parameter.
  • Syntax: %URLPARAM{"name"}%
  • Supported parameters:
    Parameter: Description: Default:
    "name" The name of a URL parameter required
    newline="$br" Convert newlines in textarea to other delimiters. Variables $br (for <br /> tag), $n (for newline) are expanded. Other text is encoded based on encode parameter. no conversion
    encode="off" Turn off encoding. See important security note below encode="safe"
    encode="quote" Escape double quotes with backslashes (\"), does not change other characters; required when feeding URL parameters into other TWiki variables. This encoding does not protect against cross-site scripting. encode="safe"
    encode="moderate" Encode special characters into HTML entities for moderate cross-site scripting protection: "<", ">", single quote (') and double quote (") are encoded. Useful to allow TWiki variables in comment boxes. encode="safe"
    encode="safe" Encode special characters into HTML entities for cross-site scripting protection: "<", ">", "%", single quote (') and double quote (") are encoded. (this is the default)
    encode="entity" Encode special characters into HTML entities. See ENCODE for details. encode="safe"
    encode="html" Encode special characters into HTML entities. In addition to encode="entity", it also encodes space, newline (\n) and linefeed (\r). Useful to encode text properly in HTML input fields. encode="safe"
    encode="url" Encode special characters for URL parameter use, like a double quote into %22 encode="safe"
    encode="search" Special encoding used for SEARCH: Substitute % characters into non-printable characters, so that TWikiVariables are no longer expanded. Also escapes quotes. Used to feed a search string from a URLPARAM into SEARCH without expanding any variables, such as when searching for %BR%. type="url"
    multiple="on"
    multiple="[[$item]]"     		If set, gets all selected elements of a <select multiple="multiple"> tag. A format can be specified, with $item indicating the element, e.g. multiple="Option: $item" first element
    separator=", " Separator between multiple selections. Only relevant if multiple is specified "\n" (newline)
    format="..." Format the result. $value expands to the URL parameter. If multiple is specified, $value expands to the result of the concatenated items. "$value"
    default="..." Default value in case parameter is empty or missing. The format parameter is not applied. empty string
  • Example: %URLPARAM{"skin"}% returns print for a .../view/TWiki/TWikiVariables?skin=print URL
  • ALERT! Notes:
    • IMPORTANT: There is a risk that this variable can be misused for cross-site scripting (XSS) if the encoding is turned off. The encode="safe" is the default, it provides a safe middle ground. The encode="entity" is more aggressive, but some TWiki applications might not work.
    • URL parameters passed into HTML form fields should be encoded as "html".
      Example: <input type="text" name="address" value="%URLPARAM{ "address" encode="html" }%" />
    • Double quotes in URL parameters must be escaped when passed into other TWiki variables.
      Example: %SET{ "lunch" value="%ENCODE{ "string with "quotes"" type="quotes" }%" remember="1" }%
    • Percent characters and double quotes in URL parameters should be escaped when passed into a SEARCH variable.
      Example: %SEARCH{ "%URLPARAM{ "query" encode="search" }%" noheader="on" }%
    • When used in a template topic, this variable will be expanded when the template is used to create a new topic. See TWikiTemplates#TemplateTopicsVars for details.
    • Watch out for TWiki internal parameters, such as rev, skin, template, topic, web; they have a special meaning in TWiki. Common parameters and view script specific parameters are documented at TWikiScripts.
    • If you have %URLPARAM{ in the value of a URL parameter, it will be modified to %<nop>URLPARAM{. This is to prevent an infinite loop during expansion.

VAR{"NAME" ...} -- get a preference value from another web or topic and more

  • Gets the value of a variable in various manners.
    • If the topic parameter is specified, it gets the value of the specified preferences variable in the specified topic. Please note that the WebPreferences of the web of the specified topic is not examined. So the returned value may not be the same as the value of the variable when the specified topic is viewed.
    • If the topic parameter is not specified and the web parameter is specified, it gets the value of the specified preferences variable in the specified web, which means the specified web's WebPreferences is examined for the variable.
    • If the neither the topic nor web parameter is specified, it gets the value of the specified variable in the current context -- the variable can either be a preferences variable or a session variable but cannot be a tag with a tag handler (e.g. %GMTIME%).
      %VAR{"NAME"}% is similar to %NAME%, but they differ if NAME is undefined, in which case %VAR{"NAME"}% is expanded to null (zero width string) while %NAME% remains as is (%NAME%). %VAR{"NAME"}% yields the same value as %IF{"defined NAME" then="$percntNAME$percnt"}% if NAME is a variable, but the latter is cubmersome.
  • Syntax: %VAR{"NAME" ...}%
  • Supported parameters:
    Parameter: Description: Default:
    "Variable" The name of the variable to be retrieved. If not specified, %VAR{...}% is expanded to null. required
    topic="Web.Topic" Specifies the topic in which the specified preferences vaiable is fetched. none
    topic="Topic" Same as above, but the web is specified specified explicitly with the web parameter or the current web is specified. none
    web="Web" Specifies the web in which the specified preferences variable is fetched. none
    default="Value" Specifies the value to be returned if the specified variable is undefined. "" (null string)
    ignorenull="on" If specified, a null string ("") value is regarded as undefined. This affects whether or not the value specified by the default parameter is returned. "off"
  • Example 1: To get the members of TWikiAdminGroup, %VAR{"GROUP" topic="%USERSWEB%.TWikiAdminGroup"}%, which expands to HenkRoelofs,RutgerRutgers,KarlGorz,JoostHoeve,NicoRos,WiljoVanLenthe,JosVos.
  • Example 2: To get %WEBBGCOLOR% of the Main web write %VAR{"WEBBGCOLOR" web="Main"}%, which expands to #FFEFA6
  • Example 3: Let's say you are writing the "foo" skin. And you want to have the users specify a string inserted in the head tag with FOOSKIN_HTML_HEAD_HOOK. That can be achived by the following:
    %VAR{"FOOSKIN_HTML_HEAD_HOOK" default="<nop>" ignorenull="on"}%

    public expands to all non-hidden webs.
    cancopyto similar to public, but webs to which a topic of the current web cannot be copied to are excluded. Specifically, excluded are read-only webs and mirror webs.
    canmoveto similar to cancopyto, but webs to which a topic of the current web cannot be moved to are excluded. Specifically, excluded are webs residing on different disks from the current web.
    webtemplate expands to all template webs, whose name start with underscore (_)
    NOTE 1: Administrators will see all webs, not just the public ones.
    NOTE 2: If MetadataRepository is used and webs are required to be registered, then cancopyto, canmoveto, and webtemplate behave differently.
    • cancopyto and canmoveto results include all top level webs and subwebs of the current webs are listed regardless of accessibility - subwebs of non-current webs are excluded. They also include the user's subweb.
    • webtemplate result has top level template webs only.
    		 "public"
    exclude="Legacy*, Sandbox" Comma separated list of webs to exclude. Wildcards can be used, such as Legacy* to exclude all webs starting with Legacy. ""

    selection="%WEB%" Current value to be selected in list selection="%WEB%"
    subwebs="Sandbox" Show webs that are a sub-web of this one (recursivly) ""
    depth="1" Specify the maximum depth of recursive search. E.g. %WEBLIST{depth="1"}% shows only top level webs. %WEBLIST{subwebs="Foo" depth="1"}% shows the direct subwebs of Foo. (no maximum depth)
    limit="30" Limit number of webs to show "" (all)
    overlimit="..." Message shown if over limit, such as: overlimit="   * [[%SYSTEMWEB%.SiteMap][More...]]" ""
    reverse="on" Reverse the order of the result. "" (off)
  • Example: %WEBLIST{"$listindent   * [[$name.WebHome]]"}% - creates a indented bullet list of all webs.
  • Example: <form><select name="web"> %WEBLIST{"<option $marker value=$qname>$name</option>" webs="Trash, public" selection="%WEB%" separator=" "}% </select></form> - creates a dropdown of all public webs + Trash web, with the current web highlighted.
