Scriptisto

This is not an officially supported Google product

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.

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 ./app // target_bin: @@@/app // 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

Installation

Install Rust, for example via https://rustup.rs/. Then install from Crates.io:

shell $ cargo install scriptisto

Or the latest from Github:

shell $ git clone https://github.com/igor-petruk/scriptisto.git $ cd scriptisto $ cargo install --path .

Creating scripts from templates

Try one of the script templates from one of the language available. To see the list:

shell $ scriptisto -g

Then generate your basic script:

shell $ scriptisto -g rust | tee ./rust-script $ chmod +x ./rust-script $ ./rust-script Hello, Rust!
