I have a bunch of things running around in my head that I’m curious  
about  
regarding IronRuby and I’m not sure where to find the answer. I figure  
my  
best bet is to drop my questions here.

The first question I have is what the current status is regarding using  
existing Ruby libraries from IronRuby. One of the use cases where I  
could  
see a lot of .NET developers using IronRuby is for writing  
specificiations/unit tests for their code. I’ve been experimenting with  
testing some really simple classes written in C# with simple test and  
I’d  
like to see if/how IronRuby could get to the next level of testing which  
might include being able to mock/stub behavior. I’ve used mocha a bit  
on a  
couple Ruby projects and am wondering if someone could help me  
understand  
where IronRuby is in regards to being able to use a ruby library such as  
mocha. The second part of the question is what is the best method for  
determining what’s needed (but not yet implemented in IronRuby) for a  
given  
ruby library to run.

Now assuming it could run an external ruby library, how would you need  
to  
setup IronRuby to properly load it? I assume that’s coming when we get  
gems

- yaml support and will just be a require ‘mocha’?

Cheers,  
Steve

You can try requiring any existing libraries out there, but you’ll  
likely to run into issues where IronRuby simply hasn’t implemented  
either syntax or built-in libraries yet. Check the archives of this  
list a bit, Wayne K. has been doing a fantastic job of testing ruby  
gem’s setup.rb file (which is the first step to alot of things), the  
wiki page for his findings is here:  
[http://ironruby.rubyforge.org/wiki/wiki.pl?TowardsRails](http://ironruby.rubyforge.org/wiki/wiki.pl?TowardsRails)

Remember, the end goal of IronRuby is to run “real ruby programs”, so  
yes it should just be “require mocha”, with perhaps some bridging  
layer (written in ruby) being required.
