Irc.rb

Ruby IronRuby
1

Hi, I’ve created an irc.rb (attached) which mimics IronPython’s pyc.py.
It
is failing on this line:

Microsoft::Scripting::ScriptCode.save_to_assembly(outfile,
codes.to_array())

With the following exception… Any help would be greatly appreciated.
The
test file I’m trying to compile is also attached. I am building on
revision
140. I have also tried with the Microsoft.Scripting and
Microsoft.Scripting.Core dlls from IronPython with the same result.

Right. This is the error Dino overheard me talking about :slight_smile: As you can
see from the stack trac, something seems to be broken in DLR. I’ll look
at it and see whether I can come with a simple fix. Precompilation is
currently P2 on our task list though, so I’m afraid any more complex
work would need to wait until P1’s are done.

Thanks! I’ve also created a bug report:

http://rubyforge.org/tracker/index.php?func=detail&aid=21839&group_id=4359&a
tid=16798

This includes the irc.rb which I think IronRuby will be interested in
including in the IronRuby distribution as well…

I’ll try to step through into this bug and understand what’s going on,
although I have no clue what I’m looking at :slight_smile:
Thanks,
