digitalmars.D - Inline D in Javascript

What about "inline D" in javascript (/php)?

What strikes me is the perfect profile of D. The compiler is fast, and the
resulting code is fast as well. Still, with some few issues (like
documentation), D is relatively easy to learn. The safety is hight, compared
with C++.

I understand that other forces than "how good it is" are of higher importance
for the direction of the development on Internet. For instance, html5 is moving
forward due to its compability with new technology, although much of its
handling of text and graphics are awkward, gaining an edge over java/flash.

Still I believe in reason as part of the development. My own primary interest
is in developing demonstration platforms for simple functions (open source). I
believe there is so much good software out there which is ignored just because
of lack of accessibility. Also D has this problem to some extent, although the
obvious solution is more people getting to use D and taking part in its growth.

Obviously, inline D would need some kind of package to make it. Then if D code
occurs in the JavaScript, it is compiled "just in time" and the machine code
temporarily stored like a (virtual) cookie. The D functions are then called
from the script in analogy to how local server scripts are called and the
result dynamically implemented.

I can see the safety issues, but how about the vision? Is the vision realistic
at all?

*** Many thanks for the link. Although I found the discussion about "inline D", and many of the idas there seemed very interesting, I must admit I have some problems to see exactly what it does. But I understand he is on a very interesting track with regard to a lot of the issues on my mind. I will dig into this and see what comes up. sincerely / Kre

Or, if you really want client side javascript, try mixing emscripten
en ldc. If you want a great server-side library, take a look at adam

*** Thankyou - then I probably misunderstood Adam Rupes post. If it takes compiled D and output JavaScript, the tool has other objectives then for demonstration.

What it does is take a D file in and spit out a javascript file. There's no speed boost from JS because it IS javascript on the output.

*** Such a beautiful idea, and very useful. It looks like mr. Jacob Carlborg went ahead and read my thoughts with that link. Firstly, I have always believed that for instance downloading someting, is an obstacle for someone who just wants to get a first grasp of a new programming language. They want to instantly and online do some tests and get a feeling before downloading something. Secondly, and maybe it is the primary goal, it can be a good development tool, especially for functions, with the capacity of immediate demonstrations. Even a more advanced programmer wants to know exacly what a function/tool does before investing further energy examining it.

*** Thankyou. Saw there were several compilers to choose among also, compared with a site like codepad.org, which is useful.

There's also a project that converts LLVM IR to JavaScript that might be of interest. https://github.com/kripken/emscripten/wiki -- /Jacob Carlborg

*** Very inspiring indeed, also from a demo-perspective. Almost hard to believe JavaScript can be made to do such havy duty stuff. I will se if I am able to add anything of worth to all this activity. First I have to learn D properly. Right now, I have only experience in other computer languages.
