Hi,

I am looking for a D2 java-script engine. I saw DMDScript but 
it's seems works only with D1 and abandoned. In an other side 
there is V8 engine but is written in c++, which certainly can't 
works fine with D code.

May I just need chose an other script language like lua which is 
written in c and already ported on D by LuaD?

Both https://bitbucket.org/ariovistus/pyd and luaD work very nicely. Personally I would always prefer to write in python or lua than javascript, where it's practical. Lua is very fast and python has some fantastic libraries.

I already have some experiences with Lua unlike javascript, but for my project javascript must be my first choice. I want do some tests to see if it's feasible to interpret directly simple QML files (QtQuick framework). Instead I only have the possibility to do something different.

I think DMDScript was ported to D2 too. Bye, bearophile

This is the latest version of my D2 port. https://github.com/blackwhale/DMDScript I do not work on it anymore but it should work just fine. In fact I tweaked it so that now it's in line with ECMAScript-v5 except for strict mode (as measured by Google's sputnik test suite). The only problem is that I haven't compiled it since dmd 2.054 or so (and speed is about 20-80x slower then V8, but blah they JIT and the stuff). Could take a good few hours to make it compile with latest dmd removing deprecated language features, fixing some old syntaxes etc. -- Dmitry Olshansky

Sadly, just because I don't have a lot of free time, I certainly fallback on Lua instead of putting my nose in DMDScript. Maybe in a far far future if my project is viable, a migration from Lua to javascript would be possible.

There's my D JavaScript engine, but it might not be mature enough

I'm implementing a JIT compiler for it as we speak.

Maxime will be doing a presentation on her JIT compiler at D Conference 2013: http://dconf.org/schedule/chevalier_boisvert.html Me, I'm really looking forward to hearing about it.

Small correction: LuaD is a wrapper, and is used together with any C API compliant Lua implementation, such as the reference implementation or LuaJIT. LuaD's radically D-ified API is not possible because it's a port (because it's not) but because the C API is so versatile in the first place :)
