I have multiple rules that are like identifierList ^ identifier, ($, asParser trim, identifier) star It parses a list of identifiers. The output is #('abc' #(#($, 'def') #($, 'ghj'))) What I like to have is an output of #( 'abc' 'def' 'ghj' ) I can produce this by changing the rule to ^ identifier , (($, asParser trim, identifier) ==> [:nodes| nodes second]) star ==> [:nodes| (Array with: nodes first) copyWithAll: nodes second ] But now the rule is uglified. It doesn't work with flatten because I it would flatten all together and I want to have the identifiers separated. What would be useful is a "skip" keyword for the parser so that it is skipped for the output nodes (that would be something like ?: in perl regex). Are there some better way to do this? thanks in advance, Norbert _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
