[Feature Request] Specify run directory

[Samuraien2]

I needed an executable that would load some files to accompany it. The problem is that the c3c run command runs the executable from your the project directory and not the build directory. Therefore the paths were different for the executable.

build/
├ executable
├ required_file.txt

Could we add an extra field to project.json where you could either specify where to run at or if you should run from build directory or project directory?

Currently i have to do
c3c compile
cd build
./run
cd ..

Hopefully I have time tomorrow.

Added as --run-dir

This seems to work.
I created a new project with c3c init check, and I modified the contents of src/main.c3 to the following:

module check;
import std::io;
// I know this is recursively imported, but I prefer explicit over implicit here
import std::io::path; 
import std::core::mem;

fn int main(String[] args)
{
	io::printn("Hello, World!");
	io::printn(path::cwd(tmem)!!.path_string);
	return 0;
}

Running this normally with c3c run does: says

Hello, World!
/home/bram/tmp/verify/check

With c3c run --run-dir build/:

Hello, World!
/home/bram/tmp/verify/check/build

Full paths also work.

There is however one thing missing: a run-dir parameter in project.json. I would expect that I could modify the targets like this:

"targets": {
	"check": {
		"type": "executable",
		"run-dir": "build"
	}
},

@BWindey it should now be work for projects too.

@lerno I am on the newest compiler but it does not seem to work. I tried both defining "run-dir" at top-level and at target-level, but they do not change the output of the program I posted previously here.

For the record, this is now my project.json:

"run-dir": "/home",
"targets": {
  "check": {
    "type": "executable",
	  "run-dir": "/home"
  },
  "foo": {
    "type": "executable",
	  "run-dir": "build"
  }
},

c3c run prints the current working directory, as does c3c run check and c3c run foo.
