One last question and I suppose the problem will be solved.
Can I also access the location where the rule got matched within the
action?
When using events I used something along the lines:
/////////////////////////////////////////////////////////////////////////
my $pos = $recce->read( \"$input", $start, $length - $start );
......................
my ($start_rule, $length_rule) = $recce->last_completed($name);
my $last_expression = $recce->substring($start_rule, $length_rule);
push @$actual_events, [$pos - length($last_expression) +1,$pos+1, $_];
#Marpa counted unicode symbol length incorrectly - so that's a work
around....
.......................
eval {$pos = $recce->resume(); };
/////////////////////////////////////////////////////////////////////////
This way I found the positions where the notations/arguments matched - can
I rewrite this using actions?
