Description Zoran Obradovic 2006-12-19 06:01:49 UTC
If I correctly understand how the parser works, parameters for parser functions
are parsed _before_ they are passed to parser function hooks. This seems awfully
wasteful, especially for #switch and different flavours of #if, where big chunks
of code, including metatemplates, are often parsed and thrown away. 

Parsing could be left up to the hook functions to do as needed, preferably with
a new way to set such hooks, so that the current extensions don't get broken.
Comment 1 Steve Sanbeg 2006-12-20 17:32:51 UTC
The simplest solution may be to add a magic word to defer parsing until later;
i.e.  {{#myfn:{{first}}|{{defer:second}}}} would parse first before the function
is called, and second after.

Although I'm not quite sure how to add a new magic word, I was able to test this
by recycling an existing magic word, and it seems to work.

This behaviour was totally changed when the new preprocessor was implemented in 2008.
