Re: [htmltmpl] loop counting

[Mathew R. <mat...@ne...>]

Having never actually tried this, I'm only about 99% sure that it will
work as "expected", which is -> the in child loop you will see the
child's counter - not the parent's counter.

Technically: the __counter__ is setup for each loop context -> the
"global_vars" thing which causes parent vars to be resolved inside the
loop, is resolved later in the output() phase and not in the parse()
phase which is where the __counter__ is set.

Your example is using a PARENT_LOOP_COUNTER - is that the name of the
variable, or was that meant to represent that you need access to the
parent's __counter__?

If it is a real variable, then your template should work as expected,
provided you use the "global_vars" option (as well as "loop_context_vars").

If PARENT_LOOP_COUNTER was just a way of explaining that you need access
to the parent's __counter__, then you are out of luck -> you will have
to find another way to do what you need.

Hope this helps,
Mathew
