I’ve checked out revision 76 of IronRuby, and finally got it setup in  
VS2008 where everything was compiling. For some reason the VS project  
file looks for the sub-projects in the wrong locations, and you have  
to redirect it to the proper project locations, and reset all the  
references.

I thought I would try to hack in a few more of the ruby string  
methods, and located the source file in the “MutableStringOps.cs” file  
in the IronRuby.Libraries project. I’ve written the code, but for  
some reason, it won’t get called. I’ve cleaned the solution, and  
built from scratch. I have a feeling I’m missing something obvious.  
I’ve continued to simplify it until now I have this:

```
    [RubyMethodAttribute("reverse", 

```

RubyMethodAttributes.PublicInstance)]  
public static MutableString/_!_/ Reverse(MutableString/_!_/  
self) {  
MutableString result = new MutableString(“reverse”); //just  
temp  
return result;  
}

When I try calling this method on a string from the ruby console, I  
get a NoMethodError. This is driving me crazy. I would really like  
to hack this together, and contribute it back, but I’m at my wits end  
here. It should work, but it’s not.

Sincerely,  
Josh

You should use the _other_ solution in that directory - IronRuby.sln.  
That points to the right locations.

You’ll need to run ‘rake gen’ from the command line to regenerate the  
Initializers.Generated.cs file.

Or you can actually use the ClassInitGenerator.exe in your output  
directory directly:

classinitgenerator IronRuby.Libraries.dll Ruby.Libraries  
LibrariesInitalizer \> Initializer.Generated.cs

copy Initializer.Generated.cs to trunk/src/IronRuby.Libraries/

recompile.

I didn’t even know there was a rake task, I’ve been doing it like that  
from the start 😉 Still fighting to make the rake files play nice on  
Cygwin…

Or more easily run GenerateInitializers.cmd from  
trunk\src\IronRuby.Libraries

Got it, thanks!

I feel a bit foolish at the moment for not seeing that.

Never-the-less, I went ahead and implemented the string.reverse  
methods and submitted the patch to rubyforge. I don’t know how  
helpful that is specifically, but I hope to contribute more down the  
line.

Sincerely,  
Josh
