[ragel-users] Go code generations

[Dan Kortschak]

Can I ask what the status of this development is? And whether there is a
framework for resolving this that someone could contribute to.

thanks

I don't have a timeline at this point. I'm not sure if anyone else is working
on it.

Regards,
Adrian

No worries. If there are any ideas of a sensible way to procede in tackling the problem I'd be happy to take a stab at it when time permits (I've had some ideas, but I'm not very happy with them so far).

thanks
Dan

I'm getting a 404 on the Redmine issue, what remains to be done on the Go
generation? I might be able to help.

The issues are available in the issues directory in the git repo:

<--->
$ cat issues/307.txt
Id: 307
Subject: go code generator is now broken
Tracker: Bug
Status: New
Fixed-Version: 7.0
Created-On: Sun Jul 17 19:40:11 -0700 2011
Updated-On: Sun Dec 25 10:51:08 -0800 2011

>From Miek Gieben:

With new Go versions Ragel breaks, as the
newest weekly release(s) restricts the use of 'goto'.

See this message from Andrew Gerrand:
http://groups.google.com/group/golang-nuts/browse_thread/thread/a27ca841a496956b/6768a0f0326a6569?lnk=gst&q=goto#6768a0f0326a6569

This will soon show up in a 'stable' release thereby breaking
Ragel's ability to generate Go code.
<--->

The central issue is how to get the state machine to do transitions
without use of goto into blocks. The only thing that I can come up with
is an additional state variable handled switch by the switch, which
doesn't seem very efficient.
