What’s the status on the IO and File classes? Is that something you  
would  
take contributions on?

I would rate that as a pretty high barrier to entry. Having File would  
make  
lots of useful scripts possible.

Hi Eric,

John M. has been looking at IO and File, however he’s swamped with  
other work at the moment. We would love some help in implementing IO and  
File, so feel free to start work on it.

John - if you have any code, feel free to share with Eric!

Thanks,  
-John

I looked at this briefly, and it looks like “RegisterClass” and  
“Load…”  
entries for IO and File are needed in  
“Builtins\Initializer.Generated.cs”.  
I’m guessing from the name that this file is generated dynamically, but  
how?

Is there some rake option to create this file? Or can I just modify it  
by  
hand?

Thanks,  
Eric

By compiling and running the program under  
utils/ironruby.classinitgenerator.

I agree that this should be in the rakefile. Together with a target to  
run gppg parser generator.

That worked! Of course now I have some other issues, but I’ll work my  
through them.

Thanks!

Ok, so I should have asked this sooner, but…

Do core classes (specifically IO, File) go into Ruby.Builtins or  
IronRuby.Libraries?

All classes that the compiler directly doesn’t depend on belong to  
IR.Libraries (currently, many of them are in Builtins though - we are  
going to take them out soon). As IO and File are not compiler  
dependencies they belong to Libraries.
