Ruby for .NET

[Arich Chanachai]

A few questions for the Ruby community:

1. Does anyone know of a project that is implementing Ruby on the
..NET/Mono platform?
2. Do tools exist to port Python code to Ruby and vice versa?
3. Does a Ruby compiler exist similar to the python compiler for Java
(Jython)?
4. How easy is it to interface Ruby to C/C++ class libraries?

Thanks folks!

3. Does a Ruby compiler exist similar to the python compiler for Java
(Jython)?

Not exactly what you asked here, but perhaps you need to look into
JRuby.

Hope that helps.

I'm not sure. There were discussions about this issue recently. Maybe
you can find a project here
http://raa.ruby-lang.org/

3. Does a Ruby compiler exist similar to the python compiler for Java
(Jython)?

Not exactly but there is Groovy - if you need the looks of Ruby and the
speed of Java. See http://groovy.codehaus.org/

4. How easy is it to interface Ruby to C/C++ class libraries?

Quite easy AFAIK. See
http://www.ruby-doc.org/docs/ProgrammingRuby/html/ext_ruby.html

Kind regards

there is a proof of concept implementation, but nothing released.
Anyway you can use rubydotnet wich is an interesting bridge (it allows
you to use every .net library but does not compile to clr)

I've seen several posts that hint that Groovy runs at Java-like speeds.
I haven't found this to be true at all. You can find one of my (very
incomplete and probably totally useless) benchmarks here:

Don't get me wrong ... I think Groovy has a lot of promise for those
living in the JVM world. However, it is still a very young language and
has some growing to do.

To kinda/sorta/but-not-really answer question #1... check out

http://www.saltypickle.com/rubydotnet/

I got it working and hooked into .NET (both straight-up objects and
WinForms stuff). It's neat, but I wouldn't use it for anything
production related. Also, I've only tested it on XP.

Cheers...

That's interesting, although I think you didn't choose optimal
implementations:

10:16:21 [source]: ruby /c/temp/ruby/fact-bm.rb
Ruby: 54.1 MicroSeconds per call
Ruby: 14.7 MicroSeconds per call
Ruby: 13.5 MicroSeconds per call

and

10:33:25 [groovy]: groovy fact.gr
Groovy: 67.2 MicroSeconds per call
Groovy: 59.4 MicroSeconds per call (HotSpot)
Groovy: 57.9 MicroSeconds per call
Groovy: 57.8 MicroSeconds per call (HotSpot)
Groovy: 57.8 MicroSeconds per call
Groovy: 57.8 MicroSeconds per call (HotSpot)

Darn, I didn't expect groovy to be *that* slow.

Kind regards
