capturing output of a plugin in a page variable

[Bob Paige <bo...@gmail.com>]

We use a naming convention on pages in our wiki, where each page name is
prefixed with the project name and suffixed with the page type. Project
pages are just suffixed with the word 'Project'. It has some limitations,
but it works for us :)

So I created a simple plugin that, given a page name, strips the prefix and
suffix as appropriate. I (confusingly) called it 'PageName'. It works like
this:

[{PageName}]

If the name of the page is 'My Project Section 5 Specification', the macro
strips off the 'My Project' (because there is a page called 'My Project' it
assumes that is the prefix) and the word 'Specification' because that is the
last word in the page name (page types are always one word).

Is it possible to capture the output of a macro in a page variable, as
described in (
http://lwa08.informatik.uni-wuerzburg.de/Wiki.jsp?page=WikiVariables)?

[{SET name='foo'}]
[{$name}]

returns 'foo'

What I want is:

[{SET name='[{PageName}]'}]
[{$name}]

Unfortunately, all I get is 'PageName'.

Great! Works like a charm.

I think I'll add this 'var=' behavior to all my plugins!

D'oh.  Now I understood what you meant :-)

There are two techniques you could use.

1) Create a custom PageFilter which does a  
wikiContext.setVariable("name",  
extractRealName(wikiContext.getPage().getName()) in preTranslate().  
This effectively creates a "{$name}" variable on every single page.

2) Create a plugin which does the same.  So you could say

[{PageName var="name"}]

and the PageName plugin would then put the page name into the "name"  
variable.  See the Counter plugin for an example how this can be done.

Almost!

[{SET name='{$PageName}'}]
[{$name}]

The reason is that [ ] is a "special" sequence. Then there are many  
kinds of special sequences:

{$name} for variable
{plugin} for plugin
PageName for page names.

Granted, this is slightly illogical.
