accessing constants from another module within Examples doesn't work

[jarmo]

When including module within ExampleGroup then constants from that module should be accessible directly without specifying module name:

module MyModule 
  MyConstant = 1 
  
  def my_method 
    2 
  end 
end 

describe "including modules" do 
  include MyModule 

  it "works" do 
    my_method.should == 2 
    MyModule::MyConstant.should == 1 
  end 

  it "doesn't work, but should" do 
    MyConstant.should == 1 
  end 
end 

Running this simple spec will produce one failure with this message:

1) 
NameError in 'including modules doesn't work' 
uninitialized constant MyConstant

But in regular Ruby everything works as expected:

class MyClass
  include MyModule

  def initialize
    p my_method
    p MyModule::MyConstant
    p MyConstant
  end
end

MyClass.new # produces 2 1 1

Ruby version?

[jarmo]

ruby 1.8.6 (2010-02-04 patchlevel 398) [i386-mingw32]
rspec version is 1.3.0

[jarmo]

The problem also exists with:
ruby 1.8.7 (2010-01-10 patchlevel 249) [i386-mingw32]

But everything is working with:
ruby 1.9.1p378 (2010-01-10 revision 26273) [i386-mingw32]

So it seems that this problem exists only with Ruby 1.8

i think that this is the problem I had when I updated to beta13. It does not happen in beta12

[dchelimsky]

Is this fixed with beta 14?

[Papipo]

Seems so, thanks a lot :D

[dchelimsky]

@jarmo - please confirm this is fixed

[jarmo]

It doesn't seem to be fixed for me. Since there's no newer version in 1.x then it's still the same in that branch, but it's also broken for me in beta 19.

Similar to #106, you're expecting lambdas to work like classes (regular Ruby), but they don't. To get this to work the way you expect I think I'd have to do something pretty invasive, which I'm trying to do less of as we move RSpec forward. I'll leave it open though. If anyone has a non-invasive means of doing this (i.e. something that doesn't redefine the included hook on Module), I'm interested.

I'm seeing a similar bug. See this gist. A few things to note:

• This is only a problem on ruby 1.9.1. The example spec passes on 1.8.6, 1.8.7, and 1.9.2.
• The constant is referenced in the same module it is defined, rather than being referenced in the example group that includes the module.

[dchelimsky]

With 1.9.2 final, I'm going to close this.
