Localization

[Joe]

I tried to localize an app. Unfortunately NSLocalizedString is not
working.
Can somebody give me a short recipe on how to localize an app in
RubyMotion?

[Greg Pasquariello]

Can you be more specific with "not working"?

NSLocalizedString is a macro and thus isn't available by default. Use code like the following to implement it yourself: https://github.com/foeken/CarenMotion/blob/master/app/extentions/kernel.rb#L5

[Ian Phillips]

The BubbleWrap library already has a wrapper for this, see https://github.com/mattetti/BubbleWrap/blob/master/lib/kernel.rb for details.

Cheers,

Ian.

Has anyone tested the YAML library in Rubymotion? 

It would be nice to have a library like https://github.com/ai/r18n for Rubymotion.

Apples localization features are great, but it could be better!

someone interested to co-recreate it?

[Eloy Durán]

FYI: If you’re going to take a look at making it work, be sure to check the one that comes with MacRuby, *not* the one that’s in MRI 1.9 (Psych).

[Joe]

I'm already using BubbleWrap, which is already very useful. Thanks
btw.

I added the language files in the resources folder, but it doesn't
work. Have you tested localization in your apps?

resources/English.lproj/Localizable.strings
resources/German.lproj/Localizable.strings

I also tried to name the folders en.lproj and de.lproj, with the same
result.

The Localizable.strings file have the key / value pairs as usual:
"Turn on" = "Anschalten";

The files are being added to the project, but it seems that they are
not used by the bundle.

Any ideas?

Cheers,
Joe

Just doing some testing and while the fix I posted earlier for localized XIB files also takes care of including the string tables, it seems that NSLocalizedString is not implemented in RubyMotion at this point since I get a method missing error.

Laurent?

[Aaron H]

OK, while the NSLocalizedString method isn't implemented, the method this calls is part of NSBundle and does get called.  So, you can get the functionality by adding this somewhere to your app.

module Kernel

  # you could name this NSLocalizedString() for compatibility's sake

  def localized_string(*args)

    key     = args.shift

    default = args.shift || key

    NSBundle.mainBundle.localizedStringForKey(key, value:default, table:nil)

  end

end

We have put quite some effort in our own localization solution and provided a RubyMotion gem for it: motion-phrase 

It allows a quite sophisticated localization workflow for RubyMotion app in combination with our localization service PhraseApp. Would be great to have some other RubyMotion devs try it out :)

Hi Manuel,

Tried this today, but I'm getting an error:

2013-06-06 11:59:29.641 Pixsee[20107:c07] nsstring.rb:16:in `development?': uninitialized constant NSString::RUBYMOTION_ENV (NameError)

from nsstring.rb:4:in `_localized:'

Seems RUBYMOTION_ENV isn't defined in the development? method. Any work around?

Thanks,

Bruce

[Manuel Boy]

Hi Bruce,

we're currently trying to figure this out. Which version of RM do you use? And can you share your Gemfile? We would love to reproduce the issue because I can't imagine why the constant should be undefined.

Thanks!

Manuel

We've just released version 0.0.4 of the Gem and shifted some things around regarding the load order. Could you check and see if this version works better for you?

Please note that we have changed the configuration options a little: https://github.com/phrase/motion-phrase#configure-phraseapp

:)

[Bruce McTigue]

Hi Manuel,

Thanks for the update. I removed the old gems and reinstalled with 0.0.4. I did get through the init fine and the new config file is created, but there is essentially the same problem, App.delegate?, line 20 in nsstring.rb, is referencing delegate? in BubbleWrap. My version of bubble-wrap is 1.3.0. Here's the exception:

Simulate ./build/iPhoneSimulator-6.0-Development/Pixsee.app

Hope that helps.

That is really strange. Which version of RubyMotion do you currently use? Are you already on 2.0?

[Bruce McTigue]

Hi Manuel,

Yeah, 2.0. I think I have a fairly vanilla RM app installation. That's why I'm trying to just do the install as I normally would. No one else having any issues?

Thanks,

Bruce

[Manuel Boy]

Hey Bruce,

can you share your Gemfile?

Please try to add motion-phrase as the last Gem in the Gemfile. We run it successfully in multiple (vanilla) RubyMotion apps so there must be a way :)

Best regards,

Manuel

[Bruce McTigue]

Hi Manuel,

Here ya go...

# A sample Gemfile

source "https://rubygems.org"

gem 'rake'

gem 'bubble-wrap'

gem 'sugarcube'

gem 'cocoapods', '>= 0.17.0'

gem 'motion-cocoapods', '>=1.3.0.rc1'

gem 'rubymotion_generators'

gem 'geomotion'

gem 'motion-phrase'

By the way, just upgraded to RM 2.1 and same result.

Thanks,

Bruce

[Manuel Boy]

I've tried the exact same setup and I don't receive any errors: https://github.com/docstun/rubymotion_test

Can you reproduce it with my repository?

[Bruce McTigue]

HI Manuel,

I can't replicate it with your repository. Afraid I'm going to have to abandon the effort. 

Thanks for the help.

Bruce

[Manuel Boy]

Hey Bruce,

just got a message from the RubyMotion guys that they're looking at the issue you're describing and are about to fix it.

So stay tuned :)

Best regards,

Manuel
