Description Goplat 2004-10-08 02:33:27 UTC
Templates inside template parameters, e.g. {{foo|{{bar}}}}, 
don't work, the parser sees the first }} as ending foo.

Comment 2 Wil Mahan 2004-10-15 19:31:23 UTC
Templates within templates like {{foo{{bar}}}} don't work, either.
The regex that replaces templates doesn't balance the braces.

Before doing something like in the attached patch, we should
make sure:
1) it's useful - I'm not sure there's any reason to make the
code more complex
2) it doesn't hurt performance
Comment 3 Egil Kvaleberg 2005-02-11 06:24:28 UTC
Templates within template arguments are defintely useful. The more templates
like infoboxes that are created, the more useful this becomes. One example: A
template for geographical coordinates (generating an uniform look as well as a
link to a map) cannot be used in templates for geographical locations :(

If there is a problem with syntax/parsing, then perhaps we can some special ugly
syntax for this case. Since 3 brackets is already used for arguments, why not go
to 4?
E.g:

{{foo{{{{bar}}}}}}
Comment 4 Egil Kvaleberg 2005-02-11 07:41:50 UTC
That said, I it seems strange from a syntax point of view why templates as
template arguments cannot be handled, when template arguments (which also
contain braces) can (for instance when using a template in another template
definition).

In response to comment 0

Hallo!

The first }} should be seen as the end of the template started with the last {{.
Implementing this would solve bug 895 and would help for bug 2148.

Comment 7 Jamie Bliss 2005-07-06 17:52:01 UTC
Probably related to this, "{{localurle:{{ns:4}}:Requested articles}}" don't work
under 1.5 (they did under 1.4).

The parser outputs "{{localurle:Astro73:Requested articles}}" (HTML) on my
private wiki (the meta namespace is "Astro73").
Comment 8 lɛʁi לערי ריינהארט 2005-10-26 11:05:03 UTC
testcase from http://eo.wikipedia.org/w/index.php?title=Ap%C5%9Deronsk&oldid=310604

{{Rusia urbo 2|Apsxeronsk||[[Krasnodara regiono]]|[[Apsxeronska distrikto de
Krasnodara regiono|Apsxeronska]]|[[1863]]|[[1947]]|{{Koordinatoj
gm|44|28|N|39|45|E}}|39,6 (2003)|03205501|86152|0}}

behaves differently then
the first example at http://test.leuksman.com/view/Ap%C5%9Deronsk

Note:
I will recommend the usage of distinct paramters for geographical coordinates
for this template at [[eo:]].

Fix for 3526 should have fixed this
Comment 10 lɛʁi לערי ריינהארט 2005-11-08 17:29:37 UTC
changed to worksforme

http://yi.wiktionary.org/wiki/%D7%B0%D7%A2%D7%A8%D7%91
includes templates in templates at two levels

Thanks for fixing this. Best regards reinhardt [[user:gangleri]]
