Hey,
I was just wondering how to do this properly,
say I want to parse a String and collect its contents while doing so. ' " ' are
not permitted unless they are escaped by a ' \ '.
A rule could look something like this:
rule(:string) { str('"') >> (str('\\"') | str('"').absent? >>
any).repeat.as(:string) >> str('"') }
While collecting everything will get collected, but it would be handy to do
something like this:
rule(:string) { str('"') >> (str('\\').ignore >> str('"') |
str('"').absent? >> any).repeat.as(:string) >> str('"') }
so that the ' \ ' won't get collected with the rest, which results in the
escape automagically being resolved :)
Is something like this possible? Is it even a good idea, or should it be done
in the transform step?
Cheers,
Jan
