I just have a gut feeling that Ruby will be a significant language for iOS/OS X development going forward. I really hope so anyway, even in its present state MacRuby is insanely fast against any other Ruby implementation. With the the resources of Apple behind it, the Ruby VM ecosystem will benefit greatly from thing like AOT MacRuby is bringing into the game. I've looked on with envy at how Node.js is getting such a boost by leveraging a component of a heavily developed consumer product. Node.js gets such incredible performance for free because of the JS VM arms race. If Ruby has the weight of a giant behind it, hopefully it will experience a similar wave. IMO Ruby is a lot better suited to async programming than JS, as it has fibers for example, making it easy to untangle the nested, continuation passing style of async code. Ruby is such a beautiful, productive language, it really deserves a giant like Apple throwing their weight behind it.

  "If Ruby has the weight of a giant behind it, hopefully it will experience a similar wave." I take it you didn't consider Sun a giant?
  - sjtgraham 16y ago
    Sun was all about Java and I think it's disingenuous to say that Sun ever threw any significant effort into JRuby further than seeing JRuby as a way to assimilate Ruby into the Java Borg.
    - jamesbritt 16y ago
      I have no idea what Sun's motivations were (and I doubt you do, either), but all the time I've been using JRuby I never got the sense there was anything going on that was designed to hook people into Java other than using the JVM. There was no more assimilation going on than what I would expect to see from Apple and MacRuby. Less, perhaps, since JRuby apps run on multiple platforms, something MacRuby apps won't do. And since JRuby itself was nothing more than a jar, developers could slip it into their usual Java environment without having to explain how or why they were installing Ruby. I've sat in JUG meetings watching JRuby explained to Java fans, and each time they crowd goes from notable skepticism to smiles and head-nodding when they see what they can do. Sun's support of Charlie, Tom, et al really helped get JRuby up to speed making it not only the fastest complete Ruby implementation but also acceptable to "the enterprise". Sun may have been all about Java, but to the extent they helped JRuby they've enabled many Java devs to be all about Ruby.

  I agree, and I think MacRuby is a great idea. Ruby in particular is very close to Objective-C in practice, and some of the latest Apple's changes to Objective-C have made it even more so. But as much as I love Ruby, MacRuby is still not that much faster than Ruby and often it is slower [1]. But that said I am not bashing MacRuby: it is still a very young project and it has a lot of potential still untapped.

I rather use Javascript and the Nitro engine (like google's V8) and explode the iOS ecosystem ten-fold of what objective-C has done already. Palm is already betting on JS, google too, so it is just a matter of time when the mobile world uses a flavor of JS for apps.
- kjksf 16y ago
  Technically (i.e. ignoring Apple's recently lifted ban on non-objective-c languages) that has been possible for a long time. See http://inexdo.com/JSCocoa http://inexdo.com/JSCocoa and http://stackoverflow.com/questions/327200/jscocoa-and-the-iphone http://stackoverflow.com/questions/327200/jscocoa-and-the-ip... I'm a Mac developer and I have to tell you that writing Cocoa apps in JavaScript is not great because JavaScript is not a great language. I would much prefer Ruby, Python or C# syntax than JavaScript syntax. It's also a reason why JSCoca hasn't taken off despite being available for almost 2 years now and why MacRuby is such a promising, although not yet production quality, project. Nitpicking: Palm didn't bet on JS but on HTML stack (of which JS is a part, but not the whole).

    Unfortunately, your opinion isn't very popular around here. People here don't seem to want to accept the fact that javascript was never designed to be a scalable general purpose language for writing large applications. It has slowly evolved over time, but is still not there. I hope something like Google'ss NaCL becomes popular, and instead of javascript slowly creeping to the server/desktop/phone because we have no choice in browser-land, the browser opens itself up to all computer languages so javascript can start feeling some competition. I even think this would be good for javascript, as it would spur the language to evolve faster.

Shouldn't the headline read something more like "Senior engineer confirms he is woking on MacRuby for iOS" -- didn't seem to me that he is implying that it is an official Apple project. reply

    But it's really more a sponsored project, not a project in the same sense as WebKit. It's more of a "sure, work on it and see where it goes" thing.
    - naixn 16y ago
      I'm not sure I agree. It was started by an Apple employee, endorsed by Apple, 90% of all commits is done by Apple employees, and is hosted on Mac OS Forge (http://www.macosforge.org/ http://www.macosforge.org/), where Apple releases its open-source projects (Webkit, launchd, libdispatch, etc.)

This would be seriously awesome! I love the cocoa frameworks, but I can't stand objective c. being able to use ruby would be a dream come true.
kjksf 16y ago
I would love nothing more than writing Mac or iOS apps in Ruby, but Apple's commitment to MacRuby isn't all that great. A quick look at commit stats for MacRuby shows that there's really just one full-time Apple person working on MacRuby, 3 others that contribute occasionally and a few non-apple people. I call that "barely committed" or "hedging your bets". For some perspective, Sun sponsored more people to work on JRuby at some point, more people worked on Rubinius at some point etc. Sorry for tempering the enthusiasm with hard, cold facts. kjkmacpro:macruby kkowalczyk$ git log | awk '/Author:/ {print $2}' | sort | uniq -c | sort -n 1 emoy@apple.com 6 watson1978@gmail.com 8 joshua.ballanco@apple.com 16 ben@tanjero.com 21 psychs@limechat.net 23 neeracher@apple.com 96 mattaimonetti@gmail.com 138 martinlagardette@apple.com 162 vincent.isambart@gmail.com 185 rich@infoether.com 211 pthomson@apple.com 227 ernest.prabhakar@gmail.com 542 eloy.de.enige@gmail.com 2377 lsansonetti@apple.com

  Assuming that Apple is doing all of their MacRuby development around this 3rd party hosted, public git server, and that Apple doesn't have version control facilities on their own private network. There is only one branch on that server, do you seriously suggest that is representative of all the development work ongoing internally at Apple and that one can infer "commitment" from what Apple has made public at this point? I'm not saying that Apple is or isn't heavily committed to Ruby, I do say that it is unsafe to conclude that they are not from the limited information provided.
  - kjksf 16y ago
    Actually, the source is hosted at git://git.macruby.org/macruby which is owned by Apple. So yes, unless you provide the evidence to support your claims, I'll assume that all MacRuby work is being done in public on macruby.org, similar to how other Apple open-source project work (llvm, WebKit, clang) and that the amount of that work is representative of Apple's commitment to the project. In comparison, if you do similar stats on other Apple projects (like llvm, WebKit) you'll see that they have order of magnitude more people working on them, producing order of magnitude more code.
aufreak3 16y ago
More than just MacRUby is to come I think. After Apple recently retracted their limitations on languages and runtimes, I'm actually drooling over the possibility of a slew of dev env apps for various languages including Squeak, SuperCollider and visual languages like Scratch. Making interactive stuff on the iPad with the power of a full programming language behind will be super fun.
