DMD Compiler as a Library: A Call to Arms

Not saying it's not worth it, just, it's strange to put them in the same sentence when one is what makes the difference between usable and completely unusable. I lived with 20-60s dirty build times for 1-line changes at symmetry, solely because of redundant compile-time recomputation—I wouldn't wish that on anybody. 10x would have been on the upper edge of tolerable, but you certainly won't get 10x for 'cheap'—and even so, latency should rightfully be measured in the milliseconds, not seconds. (~10x, incidentally, is quoted as an upper bound for newctfe here https://forum.dlang.org/post/qxiggjwhvadbpdfkidvu@forum.dlan..., had it ever materialised.)

Not built into the compiler, but Dub, the official package manager distributed with the compiler, should be what I think your concise statement is referring to.

1. yes

2. no

3. that's what this topic is about

4. yes

Thanks for checking up,

I did it on my Winows 10 machine, it's kinda too late to start it up now and run it but I'll do it tomorrow and post both the code and the error message.

Update: I did this quickly on my MBP.

Code: #include <stdio.h> #include <stdlib.h>

int main() { puts("Hello, world!"); return EXIT_SUCCESS; }

Command: dmd test.c

Error: ld: address=0x0 points to section(2) with no content in '/Users/james/.asdf/installs/dmd/2.107.0/dmd2/osx/lib/libphobos2.a[3233](config_a98_4c3.o)' clang: error: linker command failed with exit code 1 (use -v to see invocation) Error: linker exited with status 1

On my windows machine, running the following code:

#include <stdio.h>

#include <stdlib.h>

int main()

{

puts("Hello, world");

return EXIT_SUCCESS;

}

with the following command:

dmd main.c

gives the following error:

main.c(1): Error: C preprocessor directive `#include` is not supported

main.c(1): Error: no type for declarator before `#`

main.c(2): Error: C preprocessor directive `#include` is not supported

main.c(7): Error: no type for declarator before `return`

main.c(8): Error: no type for declarator before `}`

Running the c code using docker just says that it cannot process c extensions.

docker run --rm -it -v .:/src dlanguage/dmd dmd main.c

Working in programming is often a puzzle, and something useful is accomplished beyond exercising your brain.

For an analogy, if you walk to work every day instead of driving, you are accomplishing something useful beyond just the exercising.

My dad always tried to get a residence that was about a 15 min walk to work.

You don't say. Appalling, even!

And packaged in a way that allows for both JIT and AOT workflows.
