Alternative Languages on .NET and the JVM

3 08 2007

The other day I stumbled across this link on Reddit about the formation a coherent project (the JVM Language Runtime)for implementors of alternative (non-Java) languages on the JVM to get useful information and code for using the JVM. The article points out something I’d taken note of before, which is the difference in Microsoft and Sun’s attitudes towards third parties implementing languages on their virtual machines. Really, until relatively recently, Sun did not really care about such projects. They did nothing to actively stop them, but little if anything to assist them. They really only started helping out (and hiring) members of projects like JRuby after Microsoft took the lead! Microsoft, almost as soon as projects like IronPython appeared, started actively helping them and hiring their developers – what better way to draw programmers to your platform than let them use any language they want? On the other hand, Sun also spent many years trying to push Java Java Java, while Microsoft’s developer tools have always included a variety of languages, most notably Visual Basic and Visual C++ in the pre-.NET era. So perhaps Microsoft just planned support for things like this from the start, because they already needed/wanted support for multiple languages on the same runtime – really, C#, VB.NET, ASP.NET, and a number of other .NET upgrades to major Microsoft product lines ran and inter-operated on the CLR right from the get-go.

For some reason it took Sun some time to see the light on this, and it’s one of the things for which I admire Microsoft (don’t get me wrong – I have all sorts of gripes with other things they do and have done). Mainly that, and the fact that they really spend a lot of money on pure, corporate-hands-off research. Sun also does this, though not as much, with good reason. Sun is doing much better since the pain of the dot-com bubble burst, but still has a ways to go to return to it’s previous state.

Really, I’m just looking forward to the time that I can write a program in Python or Ruby, have it run normally on any *nix (BSDs, OS X, Solaris, Linux, etc.), and run correctly on the JVM or .NET (user’s choice) on Windows through IronPython, Jython (which last I heard was semi-dead), JRuby, and IronRuby. I suppose I’ll have to wait for one of the proper native Ruby VMs for Ruby to be adequately fast – I’m rooting for Rubinius.

See also Microsoft’s framework for webapps, which from what I’ve seen is basically a .NET-esque multi-language Flash competitor (currently Windows and OS X versions): Silverlight.
