First of all, you need to tell PRD that you have a line-oriented syntax rather than a whitespace separated syntax. Otherwise, newlines will be swallowed between tokens arbitrarily. And then all you really have is a command and its args:
grammar: line(s?) /\z/ { $item[1] }
line: <skip:[ \t]+> command arg(s?) "\n" { [$item[2], $item[3]] }
command: /\w+/
arg: <perl_quotelike>
That should get you started. If you have more questions, the
Parse::RecDescent mailing list can be accessed via
http://lists.perl.org.
update:My PRD coding skills may be a bit rusty, and I didn't have time to test this code. Hopefully, if you can't get it to work, it'll at least be a model to start debugging from.
update2:OK, this works:
grammar: line(s?) /\z/ { $item[1] }
line: <skip:'[ \t]*'> command arg(s?) "\n" { [$item[2], @{$item[3]}] }
command: /\w+/
arg: /\w+/ | <perl_quotelike> { $item[1][2] }
the problem is that "perl_quotelike" doesn't match a bareword! So you have to have either barewords or quoted words.
