I've googled for it a bit and searched over newsgroup messages but I can't find the post that mentioned this. I think it might have been amidst the discussion of the javascript backend. I want to download it and try it out.

The original thread is here: http://forum.dlang.org/post/icmsymtoqgkcsxwlpqgj dfeed.kimsufi.thecybershadow.net Adam's javascript backend is based on this branch, and has had quite a bit more work done on it. It is much more of an experiment than a serious backend.

Hey, thanks! Bummer, no commits in the last 3 months or so. At any rate, I almost wonder if I can compile the output C code on the OpenVMS system at work. I have a project in C I work on from time to time, but it's an uncomfortable (to say the least) environment to work with. There is stuff like this: http://h30499.www3.hp.com/t5/Languages-and-Scripting/How-do-I-get-C-program-tracebacks-to-print-SOURCE-line-numbers/td-p/5570015 If I had DMD with C-backend at my disposal, then maybe I could instrument it with a calling convention that gives me exception handling and proper debug information. Then I'd also get arrays and various other really nice D features, even with just the basics. I wouldn't bother getting the GC to work, but it'd make me consider implementing some kind of reference counting. Even without ref counting I'd have way more at that point than what I have currently with straight C code. And if I /could/ get reference counting, and if the backend were solid enough, then the thing could probably be used for writing games. I'd have the ability to output extremely portable C code to pretty much any target except the web, and there's the JS backend for that. Very enticing! I wonder what it would take to get this sort of thing merged into mainline.

It is a loooong way from being able to do that. Your best bet is probably to try and configure gdc or ldc to output c or compiled code for your platform. Completing MicroD would require porting most of druntime as well.I wonder what it would take to get this sort of thing merged into mainline.
A huge amount of work.

I was afraid you might say that. Thanks for the input!

After having done the experiment, do you feel it's a promising approach? Are there things you figure would be better done differently?

I actually found it a lot easier than expected. Most of the constructs that survive to the glue layer are c constructs, which naturally map very well to c code. Writing the actual code is quite straightforward, it's very similar to what is done in 'toCBuffer' for di generation. I never hit a roadblock, so it should be easy for someone else to continue on from there (as Adam has). That said, reconfiguring gdc or ldc to output c (or to target the intended platform) is probably a better idea than writing a new c backend. Either way, druntime needs to be ported.

Interesting! I'd forgotten about that (or possibly not heard of it?). 5 years old though. *sigh*, I wish stuff like this had taken off much earlier.
