Description Jelte (WebBoy) 2005-11-28 14:03:01 UTC
The links [[w:Wikipedia|]] and [[w:Wikipedia|{{{showas|}}}]] are the same
(showas is not given), but the result is that link 1 is a link and link 2 is
showing as [[w:Wikipedia|]].
Comment 1 Brion Vibber 2007-01-13 06:49:06 UTC
Changed subject line to clarify.

The 'pipe trick' name expansion is a transformation performed at page save time
and operates on input text, so won't apply to the results of a template expansion.
Comment 2 Dan Barrett 2007-03-28 15:45:21 UTC
The pipe trick also doesn't work in this case:

[[{{ns:project}}:my topic|]]

However, this works:

[[{{ns:project}}:my topic|my topic]]
Comment 3 P.Copp 2009-11-26 03:35:50 UTC
The pre-save-transform step can't predict to what the templates or arguments will expand in the future, so there is no way to do a correct replacement.

Suggesting WONTFIX
