texte = Hello,This is meant to spark some discussion.. a bit technical question of =whether the include tag should be changed slightly.Here is my test page:http://www.euca.us/admin/tests/include-bug/test.htmlThe main issue for discussion is that when passing a variable in an =include:[include file=3Dsomefile.inc&var=3Dsomevalue]You can=92t overwrite the var value with a text context within =somefile.inc.=20 (I am guessing it is in a scope-preferred assignment... but haven=92t =looked that deeply yet... maybe this is documented somewhere=85 I don=92t =know.)Moreso, For me, i=92m wondering if it would be more intuitive if that =var only acted within the scope of that include file (level) only.For example in my test, there is an inc2.inc. Lets assume that in =inc1.inc that I don=92t actually try to reset var with 2. In that case, =it might begood if the value of var (within inc2.inc) is literally =91[var]=92, =(un-initialized).This question addresses encapsulation for the [include] tag I guess=85 =would we want it, or would we not=85 what are the ramifications, etc..=20=In my test, if we made the encapsulation change, the value of var within =inc2.inc would be =912=92, because I had set the text var above in the =hierarchy.=20So, two questions regarding the old [include] tag for discussion: 1.) Why can=92t or shouldn't a text var be able to override a passed =variable? 2.) What about the idea of encapsulation for the passed variables?Sincerely,Donovan
