This is good work but let's be realistic - it doesn't work yet on any real C code I've tried it with.
Yeah, it doesn't support C headers yet. But an excellent prototype nonetheless.
Lol, he is a paid hype man for the Dlang community, and you should ask him about Symmetry Investments and if they are hiring.
I'm starting in July.

That isn't why Warp was discontinued. (My last change to Warp was 7 years ago.) Even with my C code, it's unsurprising to have to update a few things after 7 years.
My version of the repository is:
https://github.com/DigitalMars/dmpp
and compiles with DMD 2.067. I'll see about updating it later today. Stay tuned!

Small price to pay for an elegant language.
He implemented the ANSI C compiler here in just 5 days.
Semi-related project, using libclang to import C++ directly (with C++ templates and all the other features, regular D has C++ linking and exception support built-in): https://github.com/Syniurge/Calypso
Some quotes from the forum https://forum.dlang.org/post/[email protected] :
- Writing a C preprocessor is a nightmare. Fortunately, I already did that https://github.com/facebookarchive/warp and we can use it if we choose.
- The D code will be able to inline C code, and even CTFE it.
- There are a lot of wacky C extensions out there. We only need to implement currently used ones (not the 16 bit stuff), and only the stuff that appears in C headers.
- Without a C compiler, we're stuck with, wedded to, and beholden to libclang. I wouldn't be surprised that the eventual cost of adapting ourselves to libclang will exceed the cost of doing our own C compiler.
