When I wrote ui tags for velocity back around 1.2, I used a directive for
each tag (#textfield, #hidden, etc), which is still the format that I
prefer. The problem I ran into (and why I've never committed anything to
CVS) was dealing with parameters, and dealing with directives having to be
either inline, or body tags, but not both. I never came up with a solution
that I liked.
On what you've done. I like diretives better than a variable. Using a
variable like you were seemed... out of scope for a variable. I didn't
like .Show either (though I understood the need for it). The "key=value"
syntax I've never liked.
I like #tagname("value" "name" "label") or something like that, but that
would require a certain order for the params, which is again ugly.
I have a love/hate relationship with velocity. I love it when I'm using
it, but hate it when I try to extend it. Go figure.
