Reading through Ragel guide, I see examples like this one: # Match a word followed by a newline. Execute A when # finishing the word. main :=*(* lower+ %A *)* .

'\n'; And if not, what would be the difference ? _______________________________________________ ragel-users mailing list ragel-users@complang.org http://www.complang.org/mailman/listinfo/ragel-users
