.Net<->IR Object Mapping

Ruby IronRuby
21

I had an old version (3-4 week old). After I got the latest source and
compiles it really works. Sorry for that.

Thanks!
Shay.

That should work:

If you want to try with this class, it is defined in the
fixtures.generated.dll assembly in
Merlin\Main\Languages\Ruby\Tests\Interop\net

Thanks,

…there is no try

I just wrote up a blog post detailing, step by step, the process I
followed
to get Cucumber working with IronRuby. May be old hat to some of you,
but I
figured that documenting my process might help others going forward.

Thanks for the post! It will be very useful to people wanting to use it.
Mind if I put something similar on the “Real Ruby applications and
libraries” page?
http://ironruby.net/Documentation/Real_Ruby_Applications

I have comment about the last section:
SUPER IMPORTANT NOTE!
Any time you rebuild IronRuby, the C# compiler will erase the contents
of the directory C:\Development\IronRuby\Merlin\Main\Bin\Debug. This
includes the cucumber and cucumber.bat files. The only way I know to
rectify this is to igem install -–no-rdoc -–no-ri cucumber once again.
To avoid doing this, just have people create the cucumber.bat/cucumber
files in Merlin/Main/Languages/Ruby/Scripts/bin, where all the other
files like that are (rails.bat, rake.bat, etc). I believe that directory
already copies to a build’s $(TargetDir), but if not you can either just
add it to the path or make it copy.

My pleasure! I hope others will find the guide helpful. Pleas feel
free to link to the post and publicize it any way you see fit.

As for the cucumber executables (cucumber & cucumber.bat), or any gem
that installs executable commands, these files are installed by the
gem command, by default, in the same directory as the ruby executable.
Perhaps some combination of setting GEM_HOME and GEM_PATH could allow
them to be installed elsewhere? My RubyGems-foo is not yet advanced
enough.

I would hate for this to be a manual process for every gem install,
every time you rebuild IronRuby. I’m open to suggestions on automating
this, and ammending the post.

Shri,
I am very interested in using cucumber for my .Net projects, so I’m
willing
to give it a go at porting win32console. To that end, I’ve created a git
repo for it on GitHub:
http://github.com/hotgazpacho/ironruby-win32console

Any guidance anyone can offer would be appreciated. Thanks!
