in reply to First steps with Marpa::R2 and BNF
3 - Returned structures
First: sorry for the piecemeal replies. I'm playing with your code and refreshing my Marpa as I go - it's been a while since I played with it.
You are getting a "bogus" array because that is the default action and you haven't specified actions for Dice_Expression ::= .... You can fix it by:
Dice_Expression ::= Simple_Dice action => ::first |Dice_with_modifier_x action => ::first |Dice_with_modifier_r action => ::first
which will cause just the hash ref to be returned from $grammar->parse(\$input, 'My_Actions'). See the semantics section in the Marpa::R2 documentation.
