So lovely

C is still my first love. You can hold the whole language in your head, and it’s fast. Yes there are footguns but it’s a libertarian programming language - you’re responsible for what you build. No hand holding.

Amazing; when I tried something similar I used a "#!" line pointing to a C compiler + runner of sorts (https://github.com/radiospiel/jit). https://git.zx2c4.com/cscript/about/ is also following that approach.

What is the benefit of registering an extension via binfmt_misc?

was surprised that "sudo apt install binfmtc" works out of the box on my box (linux mint) and i can do the magic just as described here

You can already do this without using binfmt ...

  #if 0
  gcc "$0" -o "$@".out && exec ./"$@".out
  #endif
  #include <stdio.h>
  int main () { printf ("hello, world\n"); return 0; }

Usage:

  $ chmod +x print.c
  $ ./print.c
  hello, world

(Could be better to use a temporary file though.)

There's a similar cute trick for compiled OCaml scripts that we use with nbdkit: https://libguestfs.org/nbdkit-cc-plugin.3.html#Using-this-pl...

There's also tcc, which has a shebang compatible extension to allow it to be used by scripts.
