I'm stumped on creating a grammar for PRD that will parse lines like these:
SomeName val1 val2 "this is val3"
NoValDefaultsTo1
I want to match the SomeName with one rule, and then
match each of the whitespace separated values separately.
(i.e. (val1, val2, "this is val3") )
Here is my grammar:
single: key val(s) { [$item[1], $item[2]] }
| key { [$item[1],1] }
key: /\w+/
val: <perl_quotelike> { $item[1]->[2] }
Note: I know that the val terminal is not complete for what I'm trying to do.
My problem is, If I don't use the <perl_quotelike> directive,
(i.e. /.*?$/) then it grabs NoValDefaultsTo1 as a val of
SomeName instead of a key.
I am very new to PRD, any help/advise is greatly appreciated.
Thanks,
MG
Update:
P.S.
Could someone explain the difference between <leftop> and <rightop>
I couldn't find this anywhere.
