Andy/all,
$context->process(\$text);
That was easy enough; thanx.
Now for a harder (perhaps impossible) one ...
Is there any way for TT2 to know the "path" of a given variable? IOW, could I
write a custom vmethod such that, say:
[% Thing.OtherThing.subthing.pathname() %]
would print "Thing.OtherThing.subthing"? Or is that just not doable?
My ultimate goal--and maybe I'm just approaching it all wrong--is have TT2 act a little bit like a spreadsheet. So, I
could have my objects contain "formulae" that are TT2 code, such as:
Object.thing + 2
Easy enough, especially with the trick Andy just showed me. But I also want to be able to refer to the "nodes" in my
tree (i.e. the hash of hashes that I'm passing into TT2) by "relative paths". IOW, given a structure like this:
ShoppingCart
|__________Item1
|_____price = 100
|_____qty = 3
|_____ext_price = "ShoppingCart.Item1.price *
ShoppingCart.Item1.qty"
I really don't want to have to refer to price and qty with "absolute paths"
like that. I'd much prefer something like:
ext_price = "..price * ..qty"
or whatever syntax I eventually settle on. But the point is, turning "..price" into "ShoppingCart.Item1.price" is
trivial *if* I happen to know that I'm currently "on" ShoppingCart.Item1.ext_price.
Does any of that make sense? is there a whole better way that I'm just not
seeing?
