I realized it isn't a bug. Go compiler takes in consideration a distance between '//line' directive and a line with error. I added experimental support for '//line' directive at https://github.com/antage/ragel-go/tree/golang-6 I need a feedback about how to accurate go compiler report error line location in *.rl file.

So we can't rely on '//line' directive to locate errors in .rl files. _______________________________________________ ragel-users mailing list ragel-users@complang.org <mailto:ragel-users@complang.org> http://www.complang.org/mailman/listinfo/ragel-users -- WBR, Anton _______________________________________________ ragel-users mailing list ragel-users@complang.org http://www.complang.org/mailman/listinfo/ragel-users
