[antlr-interest] Fixed field

[Brian Lavender]

What's the best way to get the words out of a fixed field file? Say the title
is in the first 20 columns, and then the author is in the next 20?

Below is a feeble attempt that will get four letters, but I would like to ignore
any whitespace that occurs after the last letter before the end column.

grammar Foo;

title	:	LTR LTR LTR LTR '\n'{System.out.println($title.text);};

LTR 	:	('a'..'z'|'A'..'Z');
