[ragel-users] Bug in Go language when using %%{ write first_final; }%%

[Anton Ageev]

Ragel defines constant "[machine name]_first_final" (where "[machine name]"
is a name specified in directive "machine [machine name]").

You could rewrite the code to use this constant:

%%{
  machine sdp;

// the machine definitions are here
....
}%%

...
// go code

if cs != sdp_first_final {
...
}
