Subject: Menhir and ocamlyacc: Ambiguous grammar
Date: Tue, 1 May 2007 20:16:33 +0100 [thread overview]
Message-ID: <8E37041B-229B-4C5C-9964-C468C347E426@gmail.com> (raw)
name_shares:
| LP expr RP expr SHARES { (Some $2, `Qty $4) }
| LP expr RP { (Some $2, `All) }
| expr SHARES { (None, `Qty $1) }
| { (None, `All) }
This is intended to parse a "name" that is followed by the # of shares.
The problem is that expr itself can be LP expr LP in which case the
only differentiator is the SHARES that follows.
Is there any way to parse this using ocamlyacc or Menhir?
Thanks, Joel
