igor-petruk / scriptisto

A language-agnostic "shebang interpreter" that enables you to write scripts in compiled languages.

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, scriptisto rebuilds it and caches the result. If a script was already built, scriptisto immediately delegates to a binary with only <1 ms overhead.

Builds in Docker are available.

Advantages and use-cases are listed in the 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

Note: some templates such as rust take more time to build during the first time. The default behaviour is to supress the build logs, so do not be discouraged that you do not immediately see any output. More info in the wiki.
