undefined method `+' for class `Date' (NameError)

[naiyyar]

Hello,

I have updated ruby motion version to v5 and using xcode9.2(ios11) and getting undefined method +' for class Date' (NameError)

/.rvm/gems/ruby-2.3.1/gems/motion-support-1.1.0/motion/core_ext/date/calculation: undefined method +' for class Date' (NameError)

While 2 days ago same was working absolutely fine with xcode8.3(ios10). and before updating rubymotion version.

Thanks

@naiyyar the issue is with High Sierra: the system version of ruby was upgraded to 2.3.1 from 1.8. There is a gem that ships with Ruby called ripper which is used to determine dependencies between ruby classes. The one that ships with 2.3.1 works differently than the one that ships with 1.8. I'm working on a fix for this, but there is a work around that you can use right away. Will provide more info soon.

edit: this ended up not being the issue because the Rakefile has app.detect_dependencies set to false.

[amirrajan]

The following update to motion-support's Rakefile is a quick fix (the files array needs to include the fully qualified location of the .rb files... I'll post a more robust version soon):

Motion::Project::App.setup do |app|
  # Use `rake config' to see complete project settings.
  app.name = 'MotionSupport'
  app.detect_dependencies = false
  app.sdk_version = '10.0'
  app.deployment_target = '10.0'

  files = [
    'motion-support/motion/_stdlib/date.rb',
    'motion-support/motion/_stdlib/array.rb',
    'motion-support/motion/_stdlib/cgi.rb',
    'motion-support/motion/_stdlib/time.rb',
    'motion-support/motion/_stdlib/enumerable.rb'
  ]

  files.each do |f|
    app.ordered_build_files.delete(f)
  end

  files.each do |f|
    app.ordered_build_files.unshift(f)
  end
end

Ok. Thanks @amirrajan

Now How can i fix it in my app. Should i remove the motion-support until fix for this is available?

also i'm unable to create a new app

[naiyyar]

Now after removing motion-support Always getting below error event after removing all code from home screen

[naiyyar]

@amirrajan i forked motion-support gem and changed rake file accordingly and still getting same issue https://github.com/naiyyar/motion-support/blob/master/Rakefile

[amirrajan]

@naiyyar fully qualify the paths and see if that works?

files = [
    File.expand_path('motion-support/motion/_stdlib/date.rb'),
    File.expand_path('motion-support/motion/_stdlib/array.rb'),
    File.expand_path('motion-support/motion/_stdlib/cgi.rb'),
    File.expand_path('motion-support/motion/_stdlib/time.rb'),
    File.expand_path('motion-support/motion/_stdlib/enumerable.rb')
  ]

[naiyyar]

Not Working.
When running rake from motion-support's directory there is no error after specifying fully qualify the paths(yes before adding paths to rake there was same error)

When adding gem to my app still getting same error

[amirrajan]

It's a bug in Ruby on High Sierra it seems. Just tracked it down. Examples as screenshots.

Working on a patch for RubyMotion to get around this.

[naiyyar]

Ok i'll try this after release. For now i removed gem from the app.
Thanks @amirrajan for the help.

[amirrajan]

I'll get the exact Rakefile setup for this repo as soon as I get it working on High Sierra.

This fixes it

[colinta]

I added @jeremiahlukus's patch to master, @naiyyar can you try installing the gem from source control and letting me know if that fixes things? If it does I'll push a release to rubygems.

[wndxlori]

@colinta that did fix my problem. It's basically a workaround (commenting out the code that crashed) for the deeper issue of of the changed behaviour on High Sierra.

My concern is that we are stripping out that duration functionality. I'm not using it, but if anyone else does, this'll break their code. But who knows if anyone is even using it... it does not appear to be covered by any unit tests.
