[Ironruby-core] Cucumber / RSpec Story Runner

Are those behaviors spec'd? If not they should be.

Qualified constants (and method calls) in 'define?' are actually quite interesting.

In:

defined? x(f(1))::y(f(2))::D

methods f, x, f, y are called (in this order) and if any of them throws an exception the exception is swallowed ($! is not set).
It seems that the code should actually do something like:

begin
  x(f(1))::y(f(2)).const_defined?(:D) ? 'constant' : nil
rescue Exception
end

Also 'defined?' on a method call:

defined? foo(1,2,3).bar(1,2,3)

should do:

begin
  foo(1,2,3).instance_methods.include? 'bar'
rescue Exception
end

I just ran rspec 1.1.9 (straight from github) on IronRuby build 167, and it appears to work (I only have a simple test, but hey).

I only had to make 2 changes:

rspec\lib\spec\extensions\main.rb:26 is

args.last[:spec_path] = File.expand_path(caller(0)[1])
IronRuby still doesn't seem to handle caller quite the same as MRI. I have no idea what that code is for, but I replaced it with this as a quick hack

args.last[:spec_path] = "."

and it seemed to work.
I encountered another problem using the 'have' matcher - rspec does this

if inflector = (defined?(ActiveSupport::Inflector) ? ActiveSupport::Inflector : (defined?(Inflector) ? Inflector : nil))
IronRuby throws uninitialized constant Object::ActiveSupport, whereas MRI just returns nil - it looks like IR isn't handling defined? on nested things properly yet.

To work around this I just put

module ActiveSupport; end
at the top of my ruby file to get around the nested module issue.

And presto!

C:\development\irtest>ir rspectest.rb

.



Finished in 2.072133 seconds



1 example, 0 failures



C:\development\irtest>ruby rspectest.rb

.



Finished in 0.053 seconds



1 example, 0 failures


The only problem now is that 2.07 seconds is somewhat larger than 0.053... I am using the debug build of ir though, as that's what rake:compile seems to give me.

Just playing with VS now to see if I can build a release version and try that

Hi,



To get rspec to work you will need to modify the actual Ironruby

source.  I've raised bugs to get the changes required fixed, however I

did this based on 1.1.4, I think Cucumber will have a whole load more

bugs attached as it has more dependencies.



I know for a fact you won't be able to run Cucumber unmodified due to

existing bugs around gems.  (for example, gem needing .rb at the end

of the file to be able to find it)



However, I haven't had chance to take a closer look.

If you explicitly set the GEM_PATH before requiring gems, you should be able to use gems that are already present.  I haven't tried any other gem operations.



I assume you're running with the latest source?

Subject: [Ironruby-core] Cucumber / RSpec Story Runner



Has anyone tried to get Cucumber (or it's predecessor: the RSpec story

runner) to work with IronRuby?  I have not had any luck thus far (I am

extremely new to Ruby), and I would really like to be able to use

Cucumber to write executable feature documentation for my .NET code.



http://github.com/aslakhellesoy/cucumber/wikis



I copied it under the "lib" directory, as well as several of its

dependencies, but when I try to do "require

'cucumber-0.1.7/lib/cucumber'", ir (interactive ruby) fails with a stack

overflow.  The same thing happens when I try to require some its

dependencies manually (eg. "require 'hoe-1.8.0/lib/hoe'" and "require

'rake-0.8.3/lib/rake'"), but some work just fine (eg. "require

'polyglot-0.2.3/lib/polyglot'" and "require

'treetop-1.2.4/lib/treetop'").



I also tried to get gem working to aide me in this process, but I had

problems with that too.  Has anyone got gem working with IronRuby?



Thanks in advance!
