[antlr-interest] newbie question about nondeterminism between keywords and identifiers

[David Guy]

I have tried putting my IDENT lexer rule last, but TYPE_DATE still
matches first. No matter what order I have tried, TYPE_DATE matches
first.

 

If "mydate : date" , "mydate" gets tokenized as IDENT, TYPE_DATE,

 

I am using ANTLR 2.7.2 in case that matters.

 

I am parsing a pre-existing language that I cannot change. Actually,
"date" can be an identifier and a type.

"date : date" is valid.
