Hi all,
I am beginning to appreciate the power of grammars and the Match class.
This is truly a major asset within Perl6.
I have a question on an edge case. I was hoping to use a grammar for an
input that has meaningful indented blocks.
I was trying something like this:
token element { <.lm> [ <linetail> | $<ind>=[ ' '+ ] <level($<ind>)> ]
}
token lm { ^^ ' '**{$cur-indent} } # skip up to current indent level
My grammar has a method called within the level rule that maintains a
stack of indentations and sets a $cur-indent.
I can imagine that the inner workings of the parser (i.e. optimization)
frustrate this approach.
Is there a way to make something like this work?
Thanks,
Theo
