[pmwiki-users] Pagelist PTV wildcard usage? Possible? Opinions wanted on tagging system.

Is it possible to specify "user functions" as a pagelist selection 
criteria ? I thought I've seen it in a receipe.

Then - if you enter all the tags in a fox-field it shoul be easy to 
write such a user-function in php to do the query to a page-var.


tags are entered via fox-form in the page-var "tags" like:

:tags: tag1 tag2 tag3

then the pagelist markup could be something like:

(:pagelist match="/(tag1|tag2)/,tags" ...

or could this possibly be done by using these markup-expressions {(...)}  ?
Is it possible to extend the options of the pagelist without rewriting 
the whole pagelist-function ?

By the way: would be nice to have a "picklist" for the tag-field showing 
the already used tags (sample: tbGTD) I've two extensions like the 
datepicker which can replace or add values of a list to a field. Idea: 
below or above an tag-input-field a list of knows tags is displayed 
(each as a link (href)). Klicking on the tag, it will be added at the 
end of the tag-input-field.
