Re: [antlr-interest] Column Identification
- I am new in antlr too but will try to help if I can.
In the version of antlr (2.7.1) the column information works fine.
If I call getColumn() from a Token it gives the correct column and the
Lexer or Parser have done nothing special for that.
If you have an old version try to update antlr.
