ruby kernel does not work for me about hydrogen HOT 9 CLOSED

This is an issue with the Ruby kernel (SciRuby/iruby#29) — it just needs to skip the signature check when it's given an empty signing key.

I probably won't have time to write a PR for this myself in the next couple of days (I'm coming up against a paper deadline for a conference). It looks like you can just add another clause at this line and skip the check if the key is empty. It would be great if you or someone else would write a pull request to fix it!

should be fixed in sciruby/iruby master. But what about implementing signatures in hydrogen?

I reinstalled iruby from sciruby/iruby master. But it is still not working yet. The complete shell output is

Maybe my fix wasn't correct and @willwhitney can help out when he has time. I am totally not into atom/hydrogen, haven't used it yet.

After installing IRuby from master I get the following error (for any code, run either in Hydrogen or the notebook). Have I just done something wrong installing?

And yeah, I do want to add signing to Hydrogen at some point. At present it only ever starts kernels on localhost and can't connect to remote kernels, so it's not critical.

@willwhitney this means your ruby version is too old. But the problem in iruby with no signatures should be fixed.

It is working now if I save the file before running hydrogen!
It's a bit strange, as in the console output it seems that hydrogen is sending the expression and not the filename. However, saving the file solves the problem.

OK, glad it's working for you now!

@minad thanks for the quick fix!
