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

CALCULATE{"formula"} -- handle spreadsheet calculations outside tables

• The %CALCULATE{formula}% variable is handled by the SpreadSheetPlugin. Over 100 functions are available, such as $ABS(), $EXACT(), $EXISTS(), $GET()/$SET(), $IF(), $LOG(), $LOWER(), $PERCENTILE(), $TIME(), $VALUE().
• Syntax: %CALC{formula}%
• Examples:
  • %CALC{$EXISTS(Web.SomeTopic)}% returns 1 if the topic exists
  • %CALC{$UPPER(Collaboration)}% returns COLLABORATION
• Note: The CALCULATE variable is handled inside-out & left-to-right like ordinary TWiki variables, but it does not support functions that refer to table cells, such as $LEFT() or $T(). Use CALC instead.

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 with "quotes" and
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.
