I have a somewhat large library written in C that I want to be able to  
call from ruby and I have used SWIG in the past. Right now if I did  
this with swig it would take me several  
days, and I don’t want to risk this becoming obsolete in 3 months.

Am I right that yarv is the future? Can SWIG be used with yarv or  
would it  
be better for me to build my library into yarv? (modify the language)

I don’t want to have to write new glue code when the next release of  
ruby (or yarv) is out.

Any opinions or pointers are greatly appreciated.

Thanks in advance,  
Tom

I am not sure what you mean here. At least you don’t have to modify  
your extension for YARV (1.9).
