can't convert MotionSupport::Duration into an exact number

[gvalmon]

Strange issue, not sure if it's related with RubyMotion or MotionSupport.

When I write in motion console, it works fine:

(main)> Time.now + 1.month
=> 2014-04-05 17:56:07 +0400

But when I write the same in compiled method:

def test
   Time.now + 1.month
end

It raises exception:

app_delegate.rb:156:in `test': can't convert MotionSupport::Duration into an exact number (TypeError)

It works fine if i write Time.now + 1.month.to_i

This issue started from latest RubyMotion (2.23/2.24).

Do you know something about it?

Thanks.

That sure looks weird. I don't have the current version of RubyMotion installed, so I can't reproduce the issue. Maybe someone else can?

I can reproduce this in RM 2.24.

Steps:

1. Clone the motion-support project
2. typical bundle update, etc. nonesense
3. rake
4. in the repl: (main)> Time.now + 1.month => 2014-04-05 11:03:53 -0400
5. Open the app_delegate.rb file and replace with the code below
6. rake
7. in the console:

2014-03-05 11:04:34.587 MotionSupport[78149:80b] app_delegate.rb:7:in `test': can't convert MotionSupport::Duration into an exact number (TypeError)
    from app_delegate.rb:3:in `application:didFinishLaunchingWithOptions:'

class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)
    test
    true
  end
  def test
     Time.now + 1.month
  end
end

Same problem here

To me, this looks like it's a RubyMotion issue ... at least part of it. An expression that works in the REPL should also work in a method (given there are no locals involved, as is the case here). Maybe someone in the RubyMotion team wants to comment? @Watson1978?

Hi, guys. Indeed, this is definitely RubyMotion bug. You could track the status in http://hipbyte.myjetbrains.com/youtrack/issue/RM-475, and you could close this.

Thanks

Thanks @Watson1978! :-)

Has this been fixed? I am still getting it

$ motion --version
