Variables in this category:

ADDTOHEAD -- add HTML to the HTML head section of the current page

  • Useful for TWiki applications to add custom CSS or JavaScript to the HTML head section of a topic. Supplied TWiki variables will be expanded. %ADDTOHEAD{}% expands in-place to an empty string, unless there is an error in which case the variable expands to an error string.
  • Syntax: %ADDTOHEAD{ "..." text="..." }%
  • Supported parameters:
    Parameter: Description: Comment:
    "..." ID of the head block, such as "MY_CSS" Optional but recommended
    text="..." HTML text to add to the head section Mutually exclusive with topic=""
    topic="Web.TopicName" Name of topic that contains the full HTML text to add to the head section, such as topic="Main.MyCssTopic" Mutually exclusive with text=""
    section="name" If topic parameter is used, includes only the specified named section, as defined in the 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 Optional
    requires="..., ..." Comma-separated list of other IDs this one depends on Optional
  • Category: ApplicationsAndComponentsVariables, DevelopmentVariables
  • Example: %ADDTOHEAD{ "MYBOX_CSS" text="<style type=\"text/css\"> .myBox { height: 22px; background-color: #AFB3C5; } </style>" }% (this topic)

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="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"
    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: %SEARCH{ "%ENCODE{ "string with "quotes"" type="quotes" }%" noheader="on" }%
    • 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.

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

  • Merges the content of a specified page into the current one before rendering.
  • Syntax: %INCLUDE{"page" ...}%
  • Supported parameters:
    Parameter: Description: Default:Sorted ascending
    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
    allowanytype="on" Suppress the content type checking in including the web page specified by a URL. disabled
    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 inclusion) When a topic is included, normally TWiki variables in the included topic are expanded in the context of the inlcluded 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 parapmeter, 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
    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
    "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.     		 
    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="..." }%  
    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
    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
    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
    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
  • 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.

JQENDTAB -- end a JQuery tab within a tab pane

JQENDTABPANE -- end a JQuery tab pane

JQTAB -- start a JQuery tab within a tab pane

JQTABPANE -- start a JQuery tab pane

  • Create nice looking horizontal tab panes in TWiki topics. Write a sequence of %JQTAB{"..."}% and %JQENDTAB% pairs, and enclose them in %JQTABPANE% and %JQENDTABPANE%. Tab panes can be nested, e.g. within one tab you can add another tab pane. These variable are handled by the JQueryPlugin.
  • Syntax: %JQTABPANE% %JQTAB{"Tab 1}% ... %JQENDTAB% %JQTAB{"Tab 2}% ... %JQENDTAB% ... %JQENDTABPANE%
  • Example:
    %JQTABPANE%
    %JQTAB{"Tab 1"}%
    Tab 1 content...
    %JQENDTAB%
    %JQTAB{"Tab 2"}%
    Tab 2 content...
    %JQENDTAB%
    %JQENDTABPANE%
