Hi there, I tried to use the Ruby on Rails console with IronRuby on an application I’m building by executing “ir script/console”. Doing so ended up with an exception from RubyProcess.CreateProcess. I debugged and found out that RoR tries to execute irb.bat which is MRI’s, so I modified rails-2.3.3\lib\commands\console.rb to point to iirb.bat instead. That didn’t work as well. I continued and discovered that RubyProcess doesn’t consider bat files as executables. I don’t know if it’s on purpose but in order to fix the problem, I added the bat extension to the valid executable extension list and set the full path of iirb.bat in rails’ console.rb file. Am I doing something wrong or is my little patch correct? Thanks, Shay. ---

You can add a RubySpec spec for it to see the details of the specific Ruby API. Then if MRI and IronRuby both have the same behavior for the spec, your patch would be correct. Ie. You can use TDD to figure out the right behavior.

I would like to see if MRI uses PATHEXT in this case, but I think from talking with Tomas, that it doesn’t.

Sorry, this is a patch I missed in the docs ([http://ironruby.net/Documentation/Real\_Ruby\_Applications/Rails#console](http://ironruby.net/Documentation/Real_Ruby_Applications/Rails#console)). This behavior hasn’t changed in Rails, and I fixed it in the past without patch IronRuby, so I would suggest not patching IronRuby now to fix it. I’ll figure out what the exact patch to Rails was and post it to the documentation.
