[[template id=plugin name=conditional core=1 author="[[Joey]]"]]
|
|
[[tag type/format]]
|
|
|
|
With this plugin, you can make text be conditionally displayed on a page.
|
|
For example:
|
|
|
|
\[[if test="enabled(smiley)"
|
|
then="The smiley plugin is enabled :-)"
|
|
else="No smiley plugin here.."]]
|
|
|
|
If the specified `test` succeeds, the `then` text will be displayed,
|
|
otherwise the `else` text will be displayed. The `else` part is optional.
|
|
|
|
The `then` and `else` values can include any markup that would be allowed
|
|
in the wiki page outside the template. Triple-quoting the values even allows
|
|
quotes to be included.
|
|
|
|
The `test` is a [[PageSpec]]; if it matches any page in the wiki then it
|
|
succeeds. So you can do things like testing for the existence of a page or
|
|
pages, testing to see if any pages were created in a given month, and so
|
|
on.
|
|
|
|
If you want the [[PageSpec]] to only match against the page that
|
|
contains the conditional, rather than matching against all pages in the
|
|
wiki, set the "all" parameter to "no".
|
|
|
|
The regular [[PageSpec]] syntax is expanded with the following additional
|
|
tests:
|
|
|
|
* enabled(plugin)
|
|
|
|
Tests whether the specified plugin is enabled.
|
|
|
|
* sourcepage(glob)
|
|
|
|
Tests whether the glob matches the name of the page that contains the
|
|
conditional.
|
|
|
|
* destpage(glob)
|
|
|
|
Tests whether the glob matches the name of the page that is being built.
|
|
That might be different than the name of the page that contains the
|
|
conditional, if it's being inlined into another page.
|
|
|
|
* included()
|
|
|
|
Tests whether the page is being included onto another page.
