TIL: RubyGem executables now go in exe

Update 2015-03-20: Now cross-posted at http://bundler.io/blog/2015/03/20/moving-bins-to-exe.html.

Bundler diff: move gem bins to exe

-  spec.executables   = spec.files.grep(%r{^bin/}) { |f| File.basename(f) }
+  spec.executables   = spec.files.grep(%r{^exe/}) { |f| File.basename(f) }

I really like this new convention. Since we’ve started generating binstubs in bin, I’ve had bizarre errors resulting from forgetting that my gemspec was specifying that my gem should install all the files in bin as executables. Changing the executables directory to exe means that I needn’t worry my gem might be including binstubs as exectubles.

I had noticed that RSpec is already doing this when I wrote some code to check if RSpec was running before starting Simplecov.

if defined?(@running_tests)
  @running_tests = false
else
  @running_tests = caller.any? {|line| line =~ /exe\/RSpec/ }
end

But it turns out RSpec has been doing that since 2011.

I hope you found this helpful. :)
