Difference: VarMETA ( vs. 1)

META -- displays meta-data

• "form" - generates the table showing the form fields. See Form Definition.
• "attachments" - generate a table of 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.
• "moved" - if a topic was moved or renamed, generates a message with details and a revert link
  • prefix="...": Prefix that goes before the moved message, but only if the message is generated, default "".
  • suffix="...": Prefix that goes after the moved message, but only if the message is generated, default "".
• "parent" - display details of ancestor topics
  • dontrecurse="on": By default recurses up tree, this has some cost. Equivalent to depth=1
  • depth="...": Return only the specified ancestor.
  • nowebhome="on": Suppress WebHome.
  • 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]]"
  • separator="...": Separator between parents; default " > "
  • prefix="...": Prefix that goes before parents, but only if there are parents, default "".
  • suffix="...": Suffix, only appears if there are parents; default "".
• "formfield" - display the value of a single form field
  • name="...": name of the field.
  • 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.
  • display="on" - only used with "formfield", retrieves the displayed value of a *+values formfield type, as against the default, stored, value.
• topic="Main.WebPreferences" - optional parameter to select which topic to get the meta-data from.

Use of "formfield" is deprecated in favour of the much more powerful QUERY macro.
