Re: Parse::RecDescent Grammar Questions

Second try :)

Seems to me that this rules:

keylist:  '{' <leftop: string /[,;]/ string> '}'
association: '{' <leftop: key_value /[,;]/ key_value> '}'
[download]

will match only keylists and associations of length==2. Should not they be:

keylist:  '{' <leftop: string (/[,;]/ string>)(s?) '}'
association: '{' <leftop: key_value (/[,;]/ key_value>)(s?) '}'
[download]

to match groups of any length?

Rule One: Do not act incautiously when confronting a little bald wrinkly smiling man.

No. `<leftop: key_value /[,;]/ key_value>` [download] is equivalent to `( key_value (/[,;]/ key_value)(s?) { [ $item[1], @{$item[2]} ] } )` [download] The "(s?)" is already built in.	[reply] [d/l] [select]
