ANN: Third Drop of RubyCLR

John Lam

3/17/2006 2:18:00 AM

This is the biggest release so far of the RubyCLR bridge:

http://www.iu.../articles/2006/03/16/third-drop-...

Here's a brief summary of the current feature set of the bridge:

- Reference .NET assemblies by assembly name or by filename
- Create and manipulate .NET reference and value types
- Automatically marshal .NET reference and value types to / from Ruby
- Dynamic generation of interop code using CIL instructions
- Create and manipulate generic .NET reference types
- Discover and consume .NET interfaces on a .NET object
- Implement .NET event handlers using Ruby blocks
- Map .NET member names to Ruby names (e.g. WordCount becomes
word_count)
- Mix in Ruby Enumerable support for .NET IEnumerable types
- Dynamically access .NET XML documentation from irb (requires
text/format – to make it work uncomment require in rubyclr.rb)

There is now a pretty cool Avalon (Windows Presentation Foundation) sample
in this release. It renders math equations from a quick and dirty Ruby DSL
that I hacked up yesterday. I think it really shows off some of the cool
things you can do when you have a powerful client-side rendering engine. You
can see a screenshot here:
http://www.iu.../articles/2006/03/15/rubyclr-...

I did a lot of perf tuning in this release, so dynamic compilation time of
the interop shims should be much faster. Runtime performance is pretty good
- I can parse a 7.5MB XML doc using XmlTextReader (a pull-mode XML parser)
which results in over a million calls across the interop boundary in about
2s.

Comments / flames / suggestions / contributions are always welcome.

Cheers,
-John

Sound like this is really coming along. I wonder does the project have
a web page of its own?

An aside... but I was wondering if you could tell me exactly what a
..NET assembly is.

Thanks,
T.

Sounds great, John. I can't wait to start playing with it this weekend.

John, does this address my earlier comments about being able to create
your own assemblies with the RubyCLR "embedded cil assembler"?

Robert

a .NET assembly is what you get when you compile a .NET (C#, VB.Net...)
language into binary form.

Ok, I will take a look. Any you are using Komodo for all this dev?
Only Windows yet though or could this work also on the Mono/Linux
side?

Sounds great. But at least a month away?

Thanks,

As .NET should be portable (I never tried it), are there any chances to
use your cool assembly to write Ruby Programs on Pocket PC based systems
(which should run a NET framework on)?

I really haven't looked at what features the compact framework stuff
supports. DynamicMethod support would be an absolute minimum. Does Ruby run
on any compact framework systems?
