[antlr-interest] lexing expression ('a'..'z')+ not matching single character input

[Jim Idle]

I think that your input text holds the clue here probably. Your CR lexer rule will return a CR token if the end of line is: '\r' '\n' and will skip it if it is just '\n'. If you are running your test on Windows, then your substituent rule will fail immediately if your input text starts with one or more blank lines.

What is the input and what error (if any) are you getting when trying to run the parser?

This will return token CR...

This will skip UNIX style end of line
