Viewing Meta Data in Page Source

Changed:

<
< When viewing a topic the Raw Text link can be clicked to show the text of a topic (i.e., 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

Rendering Meta Data

Meta Data is rendered with the %META% variable. This is mostly used in the view, preview and edit scripts.

Changed:

<
< Note: Rendering meta data is currently not supported in topic text. As a workaround, use FormattedSearch on the current topic only to render form fields.

>
> You can render form fields in topic text by using the FORMFIELD variable. Example:
%FORMFIELD{"TopicClassification"}%
For details, see TWikiVariables#VarFORMFIELD.

Current support covers:

Variable usage:	Comment:
`%META{"form"}%`	Show form data, see TWikiForms.
`%META{"formfield"}%`	Show form field value. Parameter: `name="field_name"`. Example: `%META{ "formfield" name="TopicClassification" }%`

Changed:

<
< | %META{"attachments"}% | Show attachments, except for hidden ones. Options:

>
> | %META{"attachments"}% | Show attachments, except for hidden ones. Options:

all="on": Show all attachments, including hidden ones. |

%META{"moved"}% Details of any topic moves.

| %META{"parent"}% | Show topic parent. Options:

Line: 152 to 153

At present, there is no Meta Data support for Plugins. However, the format is readily extendable and the Meta.pm code that supports the format needs only minor alteration.
