digitalmars.D.learn - Embed JavaScript into D

Is there a way I can embed javascript into my D application? I 
basically want to create a modular application which allows 
adding and removing plugins by dragging and dropping them into a 
folder. I love the idea of them being editable on the fly.

Don't know about JavaScript but there is a well-maintained Lua 
integration library : https://github.com/JakobOvrum/LuaD

Also with dmd compilation speeds you actually can just compiler 
shared library binaries of the fly from D plugin sources and get 
pretty much the same thing with pure D.

I would still prefer to use a scripting language though because 
of a lot of removed complexity for simple tasks.

LuaD is great. There is also https://bitbucket.org/ariovistus/pyd/

The reason I'm not picking up any of these is purely based on my 
opinion, I hate developping in LUA or Python. Are there no 
JavaScript / PHP bindings available yet?

None that are widely known at least. There can always be some 
hidden treasures on GitHub of course. But general attitude to PHP 
and JS in this community does not seem very friendly, so this 
stuff would be surprising to find.

Yup. I'm no massive fan of Lua or Python, but in comparison to 
php and JS they look like works of genius.

You could use any C javascript lib too, but for ones already 
wrapped or something, I know there's a few D implementations of 
javascript: dmdscript 
<http://www.digitalmars.com/dscript/index.html> (written in D1 
but there's two or three ports out there to D2), an experimental 
implementation by Maxime Chevalier-Boisvert 
<http://dconf.org/talks/chevalier_boisvert.html>, and I think a 
couple more.

I also wrote a language that is kinda like javascript but isn't 
actually the same and is buggy... but might be easier to integrate
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff

get script.d and jsvar.d, don't need the other files.

usage:

import arsd.jsvar;
import arsd.script;

void main() {
     var globals = var.emptyObject;

     // add a variadic write function...
     globals.write._function = (var _this, var[] args) {
         import std.conv;
         import std.stdio;
	string s;
	foreach(a; args)
		s ~= a.get!string;
	writeln(s);
	return var(null);
     };

     // you can also add D functions pretty straightforwardly
     globals.otherFunction = (int a, int b) {
        return a+b;
     };

     // can also set values easily in D
     globals.yourValue = 10;

     import std.file;
     // read the user's code file
     interpret(readText("scriptcode.js"), globals);
     /*
          // suppose the code there is:
          // the syntax is kinda like javascript and kinda like D
          // the concat operator is D style, but function decls 
are JS style
          function foo(name) { return "hello, " ~ name; }
          // set a global variable too
          var myname = "adam"; // my language requires variables 
be declared, even if global
     */

     // and functions/variable set in the script code are also 
available via the globals object

     // extra parens are needed to call script funs because D's 
 property is broken
     auto message = globals.foo()(globals.myname); // calls the 
script function with a script variable
     import std.stdio;
     writeln(message); // write what the script returned
     globals.write()(globals.foo()("D code")); // can also call it 
with D variables/data
}



If you use my little language, you'll probably find bugs, but I 
think it is about as easy as you can get when interfacing with D: 
the jsvar module gives you a var type, in D, that works very 
similarly to the javascript style var in the script language 
(except the double parens needed when calling a function) so the 
line can be easily blurred between native and script functions, 
as you see here.

Compile easily too:

dmd yourfile.d jsvar.d script.d

D1 version is now on github:

D2 version:
http://dsource.org/projects/dmdscript-2/
pretty sure it will need tweaks to compile with current DMD version

You could rather easyly embed Mozilla Spidermonkey engine, as it 
provides a C api and D work great with C

I'm probably going with spidermonkey then. Didn't really know it 
had a C API... Thanks. :P

If your bindings end up being reusable, be sure to post them here 
so next time someone asks this, I can link to that too!

I have some bindings and simple wrappers for Ruby, if that is of interest:
