Any thoughts on RubyMotion?

[Mykn]

http://www.rubymotion.com/

Seems similar to Nu (built on the objective-c runtime)

If you watch the video (http://www.rubymotion.com/getting-started/)
at around 4:30 he begins manipulating the iOS simulator from the
command line.
That would be an awesome to do with Nu.

Funny, I actually implemented Simulator Control via Distributed Objects some days ago: https://github.com/ksjogo/nu
Take a look into the NuRemoteHost and NuRemoteClient.

I think Nu has some advantages:
No ugly syntax ObjC forced into.
No need to recompile. With NuRemote you could just send the changed the files to the simulator and it gets evaled.

My initial thought is that they've taken the open source MacRuby
stuff, applied it to iOS, wrapped it up in some niceties, and are
trying to sell it for $200 a pop. Nice trick, but it would be even
nicer if they'd pay back the open source MacRuby effort by making
RubyMotion open source as well, instead of trying to turn a quick
buck. Anyway, a person who puts two and two together may come to the
conclusion that Apple will likely provide something along these lines
at some point, for free.

RubyMotion is headed by the creator and lead developer of MacRuby (after leaving Apple).

I don't think Laurent is trying to make a "quick buck", I think he's trying to create a sustainable income source. Because he has left a cushy job at Apple for this new venture - which may or may not work out. He has said he left so that he could focus solely on RubyMotion / MacRuby instead of being put on other projects at Apple, now that MacRuby is stable.

Oh! In that case I take it all back. :) I've been living under a rock apparently, and didn't realize that was Laurent's project. If anyone deserves to make a buck  (quick or otherwise) off a MacRuby offshoot, it's Laurent!

I doubt they've fixed up the problems pointed out here:

Actually, I think to a large extent they have. MacRuby is completely
different from RubyCocoa and other bridging integrations, since
there's really no bridging going on at all. Instead, they've
implemented ruby (including most of its standard libraries) on top of
llvm and foundation, to the extent that when you create a "normal"
ruby string in Mac Ruby, you are actually creating an NSString of some
kind, etc. They've also extended ruby's method syntax to make it
somewhat more compatible with Objective-C.

Good answer, and I wasn't aware of this. Link to why you're right:

After just under two months it has 163 repositories on Github.

There is huge momentum behind RubyMotion so I'm sure it will soon come to dominate Objective-C.  I have pasted the Objective-C, Ruby and Nu versions of the Aaron Hillegass' Cocoa Programming for Mac OS X Speakline examples. The code is by A. Hillegass, B Schwartz and T Burks respectively.

---------start ruby-----------------------

class ApplicationController

attr_writer :textField, :stopButton, :startButton

attr_reader :synth, :textField

def init

@synth = NSSpeechSynthesizer.alloc.initWithVoice(nil)

synth.delegate = self

super

end

def sayIt(sender)

unless textField.stringValue.strip.empty?

synth.startSpeakingString(textField.stringValue)

end

@stopButton.enabled = true

@startButton.enabled = false

end

def stopIt(sender)

synth.stopSpeaking

end

private

def speechSynthesizer(sender, didFinishSpeaking: success)

@stopButton.enabled = false

@startButton.enabled = true

end

def awakeFromNib

@stopButton.enabled = false

end

end
