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 [email protected] <mailto:[email protected]> http://www.complang.org/mailman/listinfo/ragel-users -- WBR, Anton _______________________________________________ ragel-users mailing list [email protected] http://www.complang.org/mailman/listinfo/ragel-users
