c2run

Fork of Jason A. Donenfeld's cscript

c2run executes C code from stdin using any variety of compiler arguments. It can be used from the command line:

$ echo 'main(){puts("hello world");}' | c2run

Or it can be used at the top of scripts:

 #!/usr/bin/c2run
 main(){puts("hello world");}

One might even register .c as an executable file type:

# echo ':cfile:E::c::/usr/bin/c2run:' > /proc/sys/fs/binfmt_misc/register
$ echo 'main(){puts("hello world");}' > a.c
$ chmod +x a.c
$ ./a.c

It respects the CC environment variable, and does not create any temporary dentries that need to be cleaned up ever.
