not sure what is the probleme exactly.
if you don't put any semantic action "==> [....]"
then the parser does not produce anything, no?

Hi,
is it possible to add such a parser that would consume input, but wouldn't return anything?
Right now I do things like...
MyParser>>rule ^ ($[ asParser, anotherRule, $] asParser) ==> [ :nodes | nodes second ]
Of course when the rules are more complex, so is the block; however it seems that this is how it's done in the example parsers...
So, would it be possible to add some kind of Null/Void/Ignore/Throwaway parser, that would consume the input, but would be omitted from the result?
so the above method could be written as
MyParser>>rule ^ $[ asNullPaser, anotherRule, $] asNullParser
or
MyParser>>rule ^ $[ asParser ignore, anotherRule, $[ asParser ignore
or something else.
Thanks, Peter
