+/-0 I'd give it a +1 if TAL would support boolean operators :) Seriously, there are situations where all you need is a trivial AND or an OR expression, writing a view method to simply be able to "select" a value (like in [0]) is just too much overhead... Another use case is the passing of arguments to a method/function/whatever - you might have a tal:repeat where each iteration calls a view method and where just need to supply an argument and you can't since TALs path syntax doesn't support that (I say tal:repeat here, 'cos in other situations you _probably_ can retrieve the value from REQUEST). [0]: e.g. tal:define="foo python: bar and 'yes' or 'no'" Cheers, Igor _______________________________________________ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com
