[pmwiki-users] Page functions?

[Joachim Durchholz]

Hi all,

is there a function-style alternative to page variables?

I.e. I'd like to define something like {$add(x,y)} so that authors can 
write {$add(2,4)} and have it expand to 6.
That's a *very* silly example, of course. In reality, I'd want to do 
something like {$retrieve(datasource,key)}.

Regards,
Jo
