Hi, I searched some materials about the SIP parser writing, someone mentioned the SIP spec grammer is a ABNF, but not BNF and it's hard to use yacc to parse it. Is it true and I want to know why?
I know yacc can parse LALR grammer and does it has something to do with ABNF and BNF difference? Thanks. ABAI _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
