What, indeed!
See Meta Data Rendering for variables used to display meta data.
Current version: 1.0
name
, this appears first for easier searching (note the order of the variables themselves is defined)
%_N_
and '"' by %_Q_%

There no absolute need for meta data variables to be in a specific order, however, it does for the following reasons:
These could be done in other ways, but this adds complexity
So the order is:
When viewing a topic the Raw Text
link can be clicked to show the text of a topic (ie: as seen when editing). This is done by adding raw=on
to URL. raw=debug
shows the meta data as well as the topic data, ex: debug view for this topic
There is currently no support for meta data for Plugins. However, the format is readily extendable and the Meta.pm
code that supports the format needs only minor alteration.
Various types of meta data can be stored in topics. The data is rendered using the %META% variable. This is mostly used in the view
, preview
and edit
scripts.
Current support is fairly basic:
Variable usage: | Comment: |
---|---|
%META{"form"}% | Show form data, see Form Templates |
%META{"attachments"}% | Show attachments, exclude hidden |
options for attachments: | |
all="on" | Show ALL attachments (including hidden) |
%META{"moved"}% | Details of any topic moves |
%META{"parent [options]"}% | Show topic parent |
options for parent: | |
dontrecurse="on" | By default recurses up tree, at some cost |
prefix="..." | Prefix for parents, only if there are parents; default "" |
suffix="..." | Suffix, only appears if there are parents; default "" |
seperator="..." | Separator between parents, default is " > " |
