[stringtemplate-interest] nesting templates and getting theloop count of the outer loop

[Roel Vanhout]

Here's how I see it; the engine 'executes' outer() for the first time.
<i0>, in outer, is 0. Then, for every element, inner() is called with
the argument argument '0'. In my example, inner() would be called 2
times. So group_nr in inside inner could only be 0 for the first element
and then 1 for the second element if it is set to the value of <i0>
_inside inner_, i.e. if it is evaluated as 'the value of <i0> inside
inner'.

I may be looking at this in a too code-like way, I don't know - but is
there a way to do what I want?


cheers,

roel

if you pass group_nr = i0 to inner,  how could they have different
values?
