digitalmars.D - JavaScript is the "VM" to target for D

A new moon (downunder) brings time for new D discussion topic :-)

Myself having a long time interest in "webapp" development and given 
that the web client platform is tied to having only JavaScript 
ubiquitously available (i.e. in the browser) and having tried a zillion 
OOP wrappers and frameworks for JavaScript that don't scale for 
significantly-sized apps,

my current thinking seems to be aligning with others that JavaScript 
should be seen as the new "binary", albeit in text form, that HLLs 
should be compiling down to for "webapp" development.

Accordingly I would like to promote a discussion on the suitability of 
D, perhaps even D1, as a HLL that could possibly compile down to 
JavaScript as a better candidate language compared to some of the other 
contenders.

To set some context for this discussion consider that GWT (Google Web 
Toolkit) is basically Java transmutated into JavaScript "object code" 
which is ultimately deployed on the client though development is 
facilitated via a Java IDE.

Also there is Haxe, http://haxe.org/ , which reminds me of D1, it being 
small and concise, and, well, rather than my words, let me copy what the 
intro page says:

haXe (pronounced as hex) is an open source programming language.

While most other languages are bound to their own platform (Java to the 

multiplatform language.

It means that you can use haXe to target the following platforms :

     * Javascript : You can compile a haXe program to a single .js file. 
You can access the typed browser DOM APIs with autocompletion support, 
and all the dependencies are resolved at compilation time.
     * Flash : You can compile a haXe program to a .swf file. haXe can 
compile for Flash Players 6 to 10, with either "old" Flash<8 API or 
newest AS3/Flash9+ API. haXe offers very good performance and language 
features to develop Flash content.
     * NekoVM : You can compile a haXe program to NekoVM bytecode. This 
can be used for server-side programming such as dynamic webpages (using 
mod_neko for Apache) and also for commandline or desktop applications, 
since the NekoVM can be embedded and extended with some other DLL.
     * PHP : You can compile a haXe program to .php files. This enable 
you to use a high level strictly-typed language such as haXe while 
keeping full compatibility with your existing server platform and libraries.
     * C++ : You can now generate C++ code from your haXe source code, 
with the required Makefiles. This is very useful for creating native 
applications, for instance in iPhone development.

The idea behind haXe is to let the developer choose the best platform to 
do a given job. In general, this is not easy to do because every new 
platform comes with its own programming language. What haXe provides to 
you is :

     * a standardized language with many good features
     * a standard library (including Date, Xml, Math...) that works the 
same on all platforms
     * platform-specific libraries : the full APIs for a given platform 
are accessible from haXe


So I guess the thrust of my topic tonight is, could D somehow reinvent 
itself to fame and fortune in the high-level-language-for-JavaScript space?

Cheers and beers as usual,

I've done a significant amount of web-app development myself, but to me this seems like a bad idea. If I want to sit down and write something quickly and don't care about performance, JavaScript or Haxe are great languages to do it in and can be more productive than D. However, even the best JavaScript vm's (like V8) are on average 10x slower than C++/D. So if performance matters, I always chose D. If I write D to run on a JavaScript VM, I lose both the productivity of JavaScript and the speed of D.

Thanks for the reality check; probably it's a silly idea. Nevertheless I'm glad to have inquired as, even though I like the idea of optional static typing in Haxe, I'll be reconsidering whether using Haxe in a new web project is a good idea also. One thing I can't figure out is why Haxe is not as popular as it "should" be. Maybe for similar reasons as you say? Cheers Justin

I haven't used Haxe, but why reconsider using it? I should've also clarified that I'm usually more productive in JavaScript for small projects because it usually takes less code for the same thing, but more so in D for large ones due to the benefits of static typing.

I've been finding D can do small things really effectively too; you can even write it in a pretty javascriptish style, using closures returning functions and associative arrays all over the place. I wrote an implementation of the Javascript DOM in D2 as well: http://arsdnet.net/dcode/dom.d To use: auto document = new Document(std.file.readText("file.html")); auto e = document.getElementById("blah"); e.attribute = "name"; And you have the whole innerHTML, outerHTML, innerText, etc. etc. too. Run it through ddoc for more info. My original idea with it was just have a similar API so I can copy/paste code between D and JS with minimal modification between the two, but I've been going wild with it on the server side too, parsing custom extensions to html to make my output, or stripping useless junk out of html fetched off the web. Infinitely more useful to me than std.xml, even though I cared more about looking like the browser than following the standard. -- Adam D. Ruppe http://arsdnet.net

 Also there is Haxe, http://haxe.org/ , which reminds me of D1, it being 
 small and concise, and, well, rather than my words, let me copy what the 
 intro page says:
I believe *very* strongly in using a REAL language that then gets compiled down to worthless crap like PHP, ActionScript, etc., whenever such worthless crap platforms are necessary. Which is, of course, necessary FAR too often when you do web development, as I do. I use Haxe for any and all PHP and Flash development and I will *never* go back to direct PHP or ActionScript. Never, ever, ever, ever, EVER! PHP in particular is by far the absolute worst, most pathetic language *and* platform (PHP's idiocy extends far beyond the language itself) ever conceived and actually used in the real world (Ok, I'm not counting old mainframes). ActionScript2 and the Flash8 API are barely any better (and unfortunately, if you want *real* compatibility, AS3/Flash9 aren't really as much of an option as all the kiddie trend-whores that have infected the programming world like the pretend.) So yea, count me as one person who does go the Haxe route (including HaxeIgniter), swears by it (quite literally, as you can see ;) ), and will *never* look back. D, or at least something closer to D, would be FAR better than Haxe, though. In fact even though I just raved about Haxe, I actually hate Haxe. Yes, it's vastly superior to using direct PHP/AS, so much so that IMO there's no good reason ever to use PHP/AS directly. But Haxe is still crap anyway. Just off the top of my head, and I know I'm forgetting a lot: - The documentation is god-awful. - The allegedly-strong type system has one hell of a blatant and idiotic hole that probably won't get fixed: http://code.google.com/p/haxe/issues/detail?id=105 generics ( http://blog.dev-scene.com/abscissa/2008/03/10/i-want-my-iarithmetic/ ) look practically super-powered. (Granted, at least you can add two generic types - The syntax for defining properties is absolutely horrid, and will cause severe optical hemorrhaging in anyone who values DRY. Although, Java-type people who enjoy seeing how many millions of lines of useless boilerplate garbage their IDE can spit out while still accomplishing practically nothing will probably love it. - Everything must be in a class (or an enum)...for no apparent reason other than, apparently, to ape Java (and why anyone would ever want to ape Java is beyond me). - There are a lot of PITA PHP idiosyncrasies that Haxe doesn't really shield you from. (Example: Some dumbass sysadmin decided your PHP5 installation should have magic quotes enabled by default? You, as the app developer, still have to work around it. Haxe theoretically could automatically add code that detects and reverses it as best as possible. But it doesn't.) - I'm beginning to question the sanity of the guy in charge: http://code.google.com/p/haxe/issues/detail?id=106 (He blatantly breaks basic browser behavior for quite obviously no benefit whatsoever, he's spoon-fed a trivial fix, and...he passes it off as a user issue? WTF? Granted, it's not a major issue, but seriously, the lack of logic involved in coming to a conclusion like that just stuns me.) But yea, while Haxe has its issues, I'm still a huge proponent of the idea of compiling real languages does to the garbage ones when you're forced to use a garbage one. In fact, my Goldie project ( www.dsource.org/projects/goldie ) has that sort of thing as one of it's original motivating factors and one of its ultimate goals. However, I'm not convinced that compiling a full real language down to browser-client-JavaScript is a great idea... For one thing, something like that is going to have overhead (and JS is sluggish enough already), unless it goes the Haxe route and actually designs the language around the idea of very easy/direct translation to the base language, which of course, limits how much of an improvement the new language can actually be. The other issue I have with it is that I feel *VERY* strongly that JavaScript should *only be used sparingly*. Specifically, any web app *should* be designed and built from the start without any use of JavaScript whatsoever. This is possible 99.99% of the time (In fact, most of the times people think they need JS for something, they're full of crap. Like button rollover images, for instance: CSS handles rollover images FAR better than any JS engine ever will.) *Then* and *only* then, you can toss in little snippets of optional JS here and there to clean up various things for people who choose to have JS enabled. I know I'm in the minority on this, but I feel very strongly that that's the *only* good way to design a web app, anything else is just plain crap design. (Correction: there's no such thing as a good way to design a web app, because "good web app" is a blatant contradiction of terms since the web is an absolute shit platform for applications *period*. (/me waits for Adam Ruppe's DWS with baited breath :) ) So I guess I should have said that's the *closest* it can possibly get to being a "good" way to design a web app.) Whew! ... Can you tell I've been itching to get all that off my chest for quite some time? ;)

Sometimes I get errors from the haxe compiler, and sometimes I get errors from the PHP runtime. But if I weren't using Haxe then all the errors would be from the PHP runtime, so I count that as a net improvement. About the only problem I've seen from the extra layer of abstraction is that the PHP runtime errors show the file/line of haxe's php output instead of the file/line in the original haxe source. So you have to go to the php file that haxe generated to see where the problem occurred. However: 1. At worst, that's only a minor inconvenience. 2. It's not a completely insurmountable problem. I can think of lots of ways that problem could be mitigated, if not outright eliminated. For instance, Haxe could output a file-by-file/line-by-line mapping from the php output to the haxe source and another program could take the that info and the error message and translate back. Or PHP could add some feature or features to help in that regard (ie, something comparable to how D's "#line" feature exists to make it easy for a theoretical D preprocessor to not screw up the line numbers output by DMD). Or, in some cases, Haxe could just tighten up it's static analysis and not let the issue get to the run-time stage. Does that answer your question?

Well, it would be slow if it was run in an interpreter written in those languages, but it's compiled. People run interpreteres on top of javascript these days without any complaints.

The problem is, even if you come up with a superior alternative, there's a lots of politics in the way. Some (all?) enterprises expect to make profits from their old technology and push it further in all possible ways. It would take years or decades to replace anything without a killer application or two. They only recently started to improve Javascript performance. It's not that bad actually. And the code can be distributed in cross-platform way across the network. They have low loading times unlike applets - a big win. E.g. I've started to use google docs, the UI is nice and doesn't crash unlike buggy native office applications.

If some idiot wants to cling onto a piece of crap tech that never should have taken off to begin with, I see no good reason to help enable them by staying on the bandwagon.

For anything non-trivial, JS loading times are terrible. Better than applets, yes, but compared to non-JS sites? Yes, it's *that* bad. And by "that" bad, I mean bad enough to qualify as a bad approach.

Really, such as? The largest problem by far has been to increase the global user base of these better technologies. The most widely used side virtual machines are for Flash and Javascript. Java had a good position, but now its dying away (on the client side). Silverlight has patent issues. What else do we have? You can't just run python or ruby in a windows box -- it doesn't have any runtime support.

If I had my way, I'd just be rid of the virtual machine altogether. Simply run native programs as a restricted user. (Indeed, I'd run the browser itself with that restricted user, then let it create whatever processes it wants, possibly stripping the child processes of more privileges.) The operating system keeps it from doing anything evil. We could define a new header in the HTTP request that lists the kind of code you'd accept, from highest priority to lowest. For example, a linux box with Wine might say: X-Accept-Code: linux64; linux; win32 Meaning it'd prefer 64 bit linux apps, but if you don't offer that, it'll settle for a generic 32 bit linux binary, or a Windows one if that fails. The application is responsible for getting its own dependencies resolved - if a dll load fails, download it from your site automatically. A statically built standard library could simplify this for the programmer. This gives the programmers huge freedom by taking the code execution out of the browser's hands. Want to use a different language? Just compile it, or bundle an interpreter for it. The accept-code header could list various VMs the system has installed too. If the browser didn't send the accept-code header, you have two options: offer the binary as a download in a link or fallback on javascript. The only problem with the former is users without the right security setup probably shouldn't get used to approving binary downloads. But, fixing the browser's create process powers are the direction I'd take instead of adding more and more to their javascript interpreters. If they can create the appropriately restricted token (which they should be running under themselves anyway!), you're in business. Seems like a lot less work than what they've put in the javascript, and gives a lot more flexibility. -- Adam D. Ruppe http://arsdnet.net

It gives different kinds of flexibility. The advantage of Javascript is easy interfacing with the DOM, the html document and all kinds of powers the browser is providing. The hypertext widget is actually pretty good at modelling user interfaces even though it's not optimal by modern standards. The web applications have many contradicting goals and as a systems programmer you only have a narrow view which is from the pov of the traditional local applications. It's true that you can restrict privileges on operating system level. However, there is no cross-platform way of controlling this system manually on a proper abstraction level. If you fail to see the advantages of a middleware layer, you need to think more about it.

Yeah, this came to mind only after I made the last post. The best solution would probably be exposing the DOM objects to the child process somehow, probably in a process similar to how browser plug-ins work. Dynamically linking the DOM API to the application and passing opaque pointers to and from it should do the trick, while insulating the downloaded code from different browser implementations. Hopefully. An alternative is interpreting Javascript through a pipe to manipulate the webpage, but then the native code is kinda pointless.

I don't know what you mean here... for security, there are no controls on Javascript, you just get what the browser offers you and nothing more. An OS level security restriction would be the same thing.

The problem is, the most common object code interfaces on top of the OS have been optimized for C/C++ and that won't change anytime soon. The layer isn't really language agnostic. If favors C/C++ compatible languages.

The Javascript world is a bit naive today, but the middleware layer will likely become more complex later. You can see some security features in most browser plugins. Javascript will eventually replace these.

I'm referring to how they run browser components all as separate processes with restricted tokens to improve stability and security, not the native client, which I find completely useless.

The websites that want to cater to them can offer alternative methods, and/or gracefully degrade. The websites that don't care about them lose out on that market opportunity. Web 2.0 works like this now, but instead of operating systems, it is browsers. If you don't use IE7+ or Firefox (which require two separate code paths in a number of cases), you're pretty much on your own. Nobody cares when their website doesn't work in Lynx.

Maybe I'm just naive about this, but it would seem to me that it should be possible to have a single compiled-native-code format that could be "framed" by the client to work on the whatever the client's OS is. I mean, x86 is x86 regardless of OS. Of course, that still leaves a need for a CPU architecture request header, and 99% of sites would ignore anything but x86, but it'd be an improvement over needing both CPU and OS. Also, a web server could be set up to automatically convert or cross-compile to whatever CPU or OS was requested by the client (and then internally cached, of course). Probably involving LLVM or something. Having standard plugins like that even for just for Apache and IIS would fix the issue for 99% of sites and 99% of users. And there could certainly still be fallbacks for the oddball servers and clients. Plus, there's still other VM-bytecode possiblities besides just JVM. There's LLVM. Or you could transmit a standardized precompiled JS bytecode (even though JS may be quick to parse, I've still thought it was a bit silly to have the clients do the JS compilation since 99% of it is all the same code being sent out to all the different clients).

It probably could be done, especially if all calls were done through a dynamically linked interface. But it seems simpler to just recompile the source for the other platforms.

Yes, this should work excellently. The cross-platform aspect is the easiest thing to solve to me.

The biggest problem there is each browser would surely insist on having their own separate bytecode.

Sure, that's reasonable. I'll point out that if the VM is compromised, you're back to depending on the OS, but you'll be right to counter that it is one more hurdle for the bad guys.

The downloads say "source and toolchain".

Maybe they'll offer one once it goes live, but I wouldn't count on it. Even so, odds are good that users won't have it installed anyway.

It looks like that's something that's necessary for the sandboxing and shouldn't be difficult for compilers to provide their own options for. Maybe Walter could add options to DMC to do that (or someone could do it to DMD or LDC) and we could see if that would be enough to get things to work on NaCL. I suspect the only reason they didn't just simply submit a patch to GCC may have just been because of GCC's (IMHO) slow and nearly impenetrable submission/acceptance process (There was a modification I once made to GCC and thought about submitting a patch, but after hours of digging through their site I couldn't figure out the process. The one thing I did learn about it is that there are periods during which patches aren't accepted).

Well, that would be an issue anyway with anything along the lines of what we've been talking about. Either getting a plugin installed in people's browsers, or getting it built into browsers and then getting people to upgrade to that new browser version.

Indeed, it's hard to believe that a "web 3.0" application vendor would suddenly support several platforms after 25+ years of Microsoft dominance. The second platform might increase the development costs 10..50% and bring 4% more money. It doesn't make sense to support other platforms unless enforced by the law. This problem won't go away in the long run, on the contrary, as new (mobile/htpc/whatnot) platforms emerge. A middleware is about building the infrastructure. Later (ideally) there are no platform specific costs involved. A history lesson might help Adam. Both Apple and Microsoft are afraid of middleware solutions. That's why Microsoft corrupted Java & Javascript and Apple recently banned all non-Apple middleware tools on iPhone. The web 2.0 apps were built because people got tired of Microsoft monoculture. Web 2.0 is a crappy technology, but we haven't got anything better.

Web 2.0 emerged due to two things: a) Developers are grossly incompetent. They are too damn stupid to even recognize a correct solution when they see it, much less to use one. b) Ease of deployment. The existing web platform could be used to distribute applications without expending much effort. c) Centralized control. Being tired of Microsoft has nothing whatsoever to do with it. -- Adam D.

Cool. I just found out earlier today that my web host ( 100megswebhosting.com ) allows arbitrary CGI (ie this is the host *my* site is on, not any of my clients unfortunately...but I've been very happy with my host for a long time so I've been thinking about trying to go with either their reseller program, or at least affiliate program, for future clients, assuming the client will go for it. They seem to usually have their own hosting already though, and then I have to put up with whatever hosting idiots they decided to hire :/ ). But anyway, my host is x86 linux, so I probably won't have to deal with cross-compiling. Unfortunately, they don't do any sort of FastCGI, though :( But I've been wanting to whip up my own blog^H^H^H^Hpersonal-site software for awhile now, so I'm deciding between D and Haxe. I love D, of course, but Haxe has HaxeIgniter, a rails-like framework that I'm already neck-deep into for one of my clients. I'd like to make a rails-like framework for D, but that would take time, so I think I'm leaning towards "Haxe for now, and re-write in D if I ever get a chance."

You might be interested in this. Maybe you've already known but I just came across it a few weeks ago: http://www.anybrowser.org/campaign/ The FAQ is pretty old, and although it seems to frowns on mandatory JS it's not particularly clear about that point (it mainly focuses on browser-choice), but I thought it was pretty cool. Yet another of of my "5,000,000 projects that I want to do, if I ever have the time" is to start an updated version of that which, among other things, emphasizes not trying to cram unnecessary JS down people's throats.

D.NET (D.CLR), D.JVM, D.ECMAScript, anything except D.assembler would have a lot of market appeal. I would hesitate at D.LLVM though as that's not where the "money" is, sadly (imho).
llvm has vmkit though, which can target both .net and java runtimes, I have no idea how mature that is. It could be a route to silverlight, meaning webapps in D. SafeD might be important here for interop. http://vmkit.llvm.org/

CoffeeScript looks quite interesting : http://jashkenas.github.com/coffee-script/ and based on a similar idea to yours. Regards Alex
