[Ironruby-core] Passing a .NET object to the RubyEngine...

Nice stuff Eric,

 

Have you already passed real objects back and forth between Ruby and C#?? That
would be the real cool stuff. I will hack a little tomorrow I guess, but if you
have any tips already, that would be great.

 

Thanks

Stefan

Whoops ... missing some semicolons there.  Can you tell I spend most of my day
in VB.NET?

Here's a quick example:

RubyEngine re = RubyEngine.CurrentEngine;
IScriptModule mod = ScriptDomainManager.CurrentManager.Host.DefaultModule

  string script = "puts 'Ruby and ' + var.to_s + ' together at last'"

 mod.SetVariable("var", ".NET")

  re.ExecuteCommand(script, mod);

A couple things to note:
1. var.to_s is necessary because I don't think IR is coercing CLR Strings to
Ruby Strings yet. 
2. I'm not sure why you need to pass in the default module to ExecuteCommand,
but I wasn't able to evaluate the variable in Ruby otherwise.

Hi All, I posted some code for calling IronRuby code I found in the mailing
list onto the wiki.

 

http://ironruby.rubyforge.org/wiki/wiki.pl?ExecutingIronRubyFromCSharp 

 

  RubyEngine re = RubyEngine.CurrentEngine;

  string script = "s = 'let us get started'" + Environment.NewLine

    + "i = s.length");

  re.ExecuteCommand(script);

 

The only thing is, I don't know how to pass a .NET object to the context of the
RubyEngine so it can be called from within the script. I'd like to update the
example with that.

 

Any help?

 

Phil
