10 Forces Guiding the Future of Scripting
snydeq writes "InfoWorld examines the platforms and passions underlying today's popular dynamic languages, and though JavaScript, Perl, PHP, Python, Ruby, Groovy, and other scripting tools are fast achieving the critical mass necessary to flourish into the future, 10 forces in particular appear to be driving the evolution of this development domain. From the cooption of successful ideas across languages, to the infusion of application development into applications that are fast evolving beyond their traditional purpose, to the rise of frameworks, the cloud, and amateur code enablers, each will have a profound effect on the future of today's dynamic development tools."

I didn't read the article, but from the summary I'll assume one of the forces is gravity.
It's too bad it's such a weak force.
Well, back to rejecting software patent applications.
Does anyone know of a project to bring some of the fast Javascript implementations like V8 to the server? It could be like PHP or Perl, only very fast-- if the numbers hold out. I would like to write in the same language on the client and the server. (Java almost achieved that...)
Ya, once Perl is used in a few more places, it'll have critical mass.
It must have been something you assimilated. . . .
I'm surprised there was no mention of Lua. Besides Javascript, Lua is probably the most widely used scripting language out there. Usually its use is hidden from the end-user but it's in everything from embedded devices to World of Warcraft.
It has a very simple design and is very fast (especially with LuaJIT). The semantics are similar to Javascript but Lua is a lot more pure and simple. There probably will never be a Javascript engine as fast as the fastest Lua engines.
Larry Wall nabbed Python's object system when he created Perl...
Erm, WTF? Perl was released in 1987; Python was 1991.
Don't thank God, thank a doctor!
Most human wars throughout the ages are based on religion. Scary, isn't it?
You think that's scary, you should've seen the camel wars.
So, I read the rest of the article, to see if he got anything else right. Well...
But will PHP be able to shake the casual structure that encourages beginners to whip up spaghetti code? Will it be able to continue to mix the presentation layer and the application layer without driving everyone insane?
It's true that PHP encourages this, and I find it a little disturbing that people are building web frameworks in what is essentially a Turing-complete template language. It would be as if the next big thing was written in PostScript.
But in a larger sense, this isn't nearly as relevant as how you use it. Drupal is proof that you can do good things with PHP.
However, I do prefer to work in a language that helps, rather than hinders, such a design.
Some want to place their bets on Ruby on Rails, a striking and elegant solution that produces sophisticated results in no time.... This simplicity often turns into shackles when the programmers reach the edge of the framework's capabilities. Changing little details or producing slightly unorthodox output can be maddening.
That's downright flamebait.
I suspect that many Rails developers do feel this way, for the same reason that many PHP programs are useless spaghetti code -- as a complete side effect. Since Rails is so easy to get into, it's a rude awakening when you need to do something it doesn't provide -- you're finding out just how much work Rails has done for you.
But seriously, "slightly unorthodox output"? Are you serious? Probably one of the easiest things to do is add another view of the same data -- even in another format.
A programmer gets the rock-solid foundation of compiled Java code mixed with the flexibility to diddle with the Java objects in real time.
Maybe Groovy makes that easier, but Java already had reflection. Next!
thanks to the lightning performance of the new JavaScript semi-compilers, the language is bound to look even more attractive.... The semantic barriers won't be as important as the languages rush to steal good ideas from one and other.... In five years, there's a good chance you'll be able to imagine you're writing Python while the code is interpreted by something called JavaScript.
Interesting ideas. None of which apply to Javascript, now or ever.
You see, Javascript client-side is a nightmare, because you have to make it work in several existing browsers, which don't always play nice with the standards.
And Javascript, the language, is evolving at an incredibly slow pace -- mostly because it's got the worst case of cruft of any language. Add an interesting feature in a browser, and you probably break some client code. Even if you're careful, as a developer, I can't use your feature if it isn't also present in other browsers.
So changing the core syntax of the language is right out. If we were to break backwards compatibility in such a dramatic way, it'd make a lot more sense to port Python to the browser.
In which case, we may as well use Java or Silverlight -- plenty of dynamic languages target these. My personal favorite would probably be JRuby in an applet.
Libraries such as Dojo and jQuery aren't just a set of helpful routines; they actively tweak the language and ask you to adopt a particular set of idioms.
True enough -- except that in the case of jQuery, it actually doesn't force anything. If you really like wasting time, you can write using the old idioms you learned. If you don't like jQuery, you can always rename the $ variable and pretend it doesn't exist.
The focus really should be on the next point, which is actually a good one:
Applications are becoming their own worlds.
Especially in a dynamic language, any body of code of sufficient size is going to have some idioms of its own.
The main reason frameworks are important
