Match at least 1 of the following

[Alex Matchneer]

Hi, I posted the following sort of question to SO: http://stackoverflow.com/questions/14471921/how-do-i-dry-this-pegjs-rule

I'm tempted to use something close to this:

id:idShortcut? classes:classShortcut* attrs:fullAttribute* 

But i don't want it to match if all three are empty/absent. Is there a way to do this in peg? Right now i have a really repetitive 3 prong rule.

I see you already answered your question yourself :-) I just want to
add that I don't think there is a better solution than the one you
figured out.
