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

```c

!/usr/bin/env scriptisto

include

include

// scriptisto-begin // scriptsrc: main.c // buildcmd: 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; } ```

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