Where's the "IronPerl" Project? 390
pondlife writes "A friend asked me today about using some Microsoft server components from Perl. Over the years he's built up a large collection of Perl/COM code using Win32::OLE and he had planned on doing the same thing here. The big problem is that as with many current MS APIs, they're available for .NET only because COM is effectively deprecated at this point. I did some Googling, expecting to find quickly the Perl equivalent of IronPython or IronRuby. But to my surprise I found almost nothing. ActiveState has PerlNET, but there's almost no information about it, and the mailing list 'activity' suggests it's dead or dying anyway. So, what are Perl/Windows shops doing now that more and more Microsoft components are .NET? Are people moving to other languages for Windows administration? Are they writing wrappers using COM interop? Or have I completely missed something out there that solves this problem?"

The biggest reason is that Python is a fairly small language with a well-defined spec.

If you write a Python program you are programming for the defined language and usually not for the quirks of any one implementation.
Perl 5, on the other hand, is very much defined by its single implementation, full of odd quirks and things that don't really make any sense but have to be kept for compatibility. To implement a fully compatible Perl 5 you would essentially need to reproduce the guts of the existing perl source code, which is why nobody has really bothered.

Opinionated post follows, feel free to ignore or disagree....
Perl is the original language that taught a whole generation of programmers that you don't have to write 1000s of lines to do a simple thing. I love its expressiveness, its design philosophy (There's More Than One Way To Do It) and its linguistic roots. Despite being known for write-only shit, actually writing clean, maintainable code in perl is a pure pleasure. It just gives you the extra bit of latitude in your coding, that what you write can express not just what you want done, but a little extra bit of how you think of it... by using "unless" instead of "if" at times, putting the conditionals after the statement at others, you can actually make the code read like the main points are main points, adn the accessory checks are accessory. I love that flexibility.
For years, perl was the secret productivity tool of many. What others would spend weeks writing in C++ or java whatever, a perl coder would prototype in a day or two, and often the result was good enough to be declared final. And with the amazing collaboration experiment called CPAN, there was a good chance you would find a module to do the heavly lifting for you, and the two days could be shortened to a couple hours.
Sadly, the perl development community missed not one, but two boats.
First, it missed the second wave of web programming. Perl was virtually synonymous with CGI programming, but then the web world moved on to embedding code inside the HTML, which is a rather crappy combination but is easy to start with. So the perl guys produce mod_perl and about a thousand templating kits, which all together made mod_perl a powerful, scalable, flexible web platform that was at the same time confusing, hard to learn, and unfriendly towards shared hosts. And then PHP came to fulfil that need, with their bastardized watered down clone of the language, and basically stole the show.
Second, the perl community in all their wisdom, back in 2000, decided that the whole language needed to be redesigned from scratch, and built on a new generic virtual machine for dynamic languages, which would run not only perl6 but also python, tcl, logo, and who knows what else. They embarked on a prolonged process of design by committee, which 8 years later has just managed to produce a variety of incomplete specifications, and two incomplete prototypes of the language interpreter, with no completion date nor any backwards compatibility to be seen. In the meantime, the whole .NET framework has been created and gone through several iterations, Ruby has risen from obscurity to fame, etc. For all we know, perl6 may still one day reach completion, and be a useful language. The design specs are way cool, and the people implementing it sound like they are having fun.
So what happens with perl and .NET? Well, not much. Apparently ActiveState have at some point developped a bridge of some kind, but I can't find it in CPAN. There's Inline::Java, but no Inline::CSharp. Maybe no-one cares enough.

The Iron* family of languages are re-implementations from scratch of a language to run on top of .NET. This approach requires a large time investment to get it working as reimplementing a language and then tuning it to run fast is not a weekend hack.
There is another option, to build bridges from a language to .NET. This is possible because .NET can be used as a library, Perl can host .NET and then create objects and send messages to objects living in the .NET world.
For a language in continuous evolution like Perl, following the Iron* route is more difficult, and the second approach might be better.
I believe there used to be a set of .NET bindings for Perl.

No, a Perl lover will jump in and say Perl is FAST to write. Its so easy to do so many things. I'm not talking large systems here, I'm talking things you need to do day to day.
I've yet to find another language where I can process a text file 100 different ways with just a few lines. I really don't give a damn if anyone else can read or maintain my short scripts. There for me.

The figures on this simply don't support that claim. Your anecdotal evidence of two places you worked it meaningless.
If anything I'd say this is because many people consider Perl's time to have passed and no longer see a reason to use it in any significant project. Perl is a typical example of a jack of all trades, master of none. These days with so many well-designed languages to choose from it's a great deal easier and more productive to learn several languages that each do one paradigm well and use them

Ho, lo, and behold. Many people consider that, and many don't.

A quote from CIO.com story entitled "PHP, JavaScript, Ruby, Perl, Python, and Tcl Today: The State of the Scripting Universe" (8/29/08)
"Of all the scripting languages, Perl offers the biggest installed base of applications, of code, of integrated systems, of skilled programmers. It has the lowest defect rate of any open-source software product. It is ported to essentially every hardware architecture and operating systems, from embedded control systems to mainframes. It is optimized for speed, for memory footprint, for programmer productivity. It has readily-accessible libraries for all types of programming tasks: Web application development, systems and network integration and management, end-user application development, middleware programming, REST and service-oriented architecture programming. Perl is ideal for the organization that takes charge of its own IT future."

I love perl in the windows world it allows us with skills to have yet another noose around the neck of management.
VB.NET was our first noose for management. I was so glad when Microsoft made VB hard. Almost all the part time VB programmers in the office instantly were ineffective as they could not wrap their heads around OO programming.
Problem is, there are still millions of VB6 applications in use today in corporations all over america... and one day micrsoft will do something to break every one of them.

I wouldn't say everyone is moving away from Windows, my last job was very Microsoft centered. Windows workstations everywhere, Exchange server, IIS servers, Microsoft SQL, Active Directory, all that bullshit.
But, I do think anyone using Windows is very unlikely to use Perl; they just seem diametrically opposed. One being used for Unix administration since large systems were in their infancy, and the other one being a the-suits-picked-it decision. At least in my (very biased) opinion.

Your theory appears to be that Windows is a good web platform, because on netcraft, 2 out of the top 50 sites by uptime are running Windows. Wouldn't the goodness of a web platform depend on a whole bunch of things, only one of which would be uptime? And uptime would be less important than things like availability and ease of installing software. And most importantly, whether the machine has a blue or green LED for the power light. Obviously machines with blue power LEDs suck, but machines with green LEDs rock! And Windows web servers always have blue LEDs for power lights! Windows sucks and always will. They don't even know how to write drivers for green LEDs.

It'd be interesting to see what the distribution of web servers between Windows & the rest is when you completely take out the uptime.

Maybe the 2 windows servers listed are just administered by brilliant admins, have zero load or run on a hardware/software combo that has been untouched since Windows 2003 was actually released...
