Run compiled language files as if they were scripts

RunC

Run compiled language files as if they were shell scripts.

Example

$ cat main.c
#include <stdio.h>

int main()
{
	printf("Hello, World!\n");
	return 0;
}

$ runc main.c
Hello, World!

To debug with gdb:

$ runc -d main.c

How it works

RunC compiles the source file using some default compiler flags and invokes the built executable, passing on any other arguments. The executable is cached in ~/.runc/caches/<hash>, where hash is a SHA-1 hash of the full file.

The default compilation command line is:

clang -Wall -std=c99 <filename> -o ~/.runc/caches/<hash>

RunC is not limited to C programs. Use a hint comment to supply a different command line:

/*! mcs /ref:SomeLib.dll */

class Program
{
	public static void Main()
	{
		System.Console.WriteLine("Hello, World!");
	}
}

This file would be compiled like so:

mcs /ref:SomeLib.dll <filename> -o <filename> ~/.runc/caches/<hash>

This will work as long as the compiler accepts the -o option and the resulting executable can be ran directly by the shell.

It is also possible to supply only cflags:

/*! -lcrypto -g */

Hints will be interpreted as solely cflags when the first non-whitespace character is a -. For this example, the resulting command would be:

clang -Wall -std=c99 -lcrypto -g <filename> -o ~/.runc/caches/<hash>
