[Templates] Accessing "global" vars inside an INCLUDE

[prev] [thread] [next] [Date index for 2004/05/21]

 I've got a template that uses INCLUDE so the block's variables are
localised. However there's a "global" variable I need to update inside the
block (to keep track of a count in this instance). I've worked around it by
passing a hash to exploit the fact that the localisation isn't a deep copy,
but this seems kind of icky. Is there something nicer?

[% SET count = { count => 1 } %]
[% INCLUDE test_block global=count %]
[% INCLUDE test_block global=count %]
[% INCLUDE test_block global=count %]

[% BLOCK test_block %]
 [% SET i = 0 %]
 [% WHILE i < 10 %]
   i = [% i %], count = [% global.count %]
   [% i = i + 1; global.count = global.count + 1 %]
 [% END %]
[% END %]

Cheers,
Gavin.
