Scriptisto

It is tool to enable writing one file scripts in languages that require compilation, dependencies fetching or preprocessing.

It works as a "shebang" for those scripts, extracting build instructions from comments. If a script is changed, it rebuilds it and caches the result. If it was already built, it immediately delegates to a binary with only <1 ms overhead.

Also useful for non-compiled languages like Typed Python, but type validation is slow and a good idea to do it once after very change. More advantages are listed in Wiki.

Demo

#!/usr/bin/env scriptisto

#include <stdio.h>
#include <glib.h>

// scriptisto-begin
// script_src: main.c
// build_cmd: clang -O2 main.c `pkg-config --libs --cflags glib-2.0` -o ./script
// scriptisto-end

int main(int argc, char *argv[]) {
  gchar* user = g_getenv("USER");
  printf("Hello, C! Current user: %s\n", user);
  return 0;
}

$ chmod +x ./script.c
$ ./script.c
Hello, C! Current user: username
