Introduction📜

AssistScript is a simple scripting(?) language that I made for fun. Not very useful, but it's fun to play around with. Initially started as a joke, and as time passed it became a fun project to work on.

The language is a straightforward, all you have to do is to specify a command and its arguments. The basic syntax is:

<command> <arg1> <arg2> ... <argN>

eg:

add 10 20 40

Outputs 70

Installation📲

You can install AssistScript using npm.

npm install -g assistscript

This installs the AssistScript CLI globally on your system. If you don't want AssistScript to be installed globally, you can omit the -g flag or use npx to run AssistScript without installing it.

Demos▶️

Want to see what the language can do? Check out the demos🧪 directory for some examples.

These demos are simple programs that demonstrate the language's features. You can run them using the CLI.

Sample Program - Bubble Sort🔢

Here is bubble sort in AssistScript:

(array arr 4 5 2 4 5 6 7 1)

(for (set i 0) (lt (get i) (len arr)) (incr i) (
    (for (set j 0) (lt (get j) (sub (len arr) (get i) 1)) (incr j) (
        (if (gt
                (index arr (get j))
                (index arr (add (get j) 1))
        ) (
            (set temp (index arr (get j)))

            (set-arr arr (get j) (index arr (add (get j) 1)))
            (set-arr arr (add (get j) 1) (get temp))
        ))
    ))
))

(for (set i 0) (lt (get i) (len arr)) (incr i) (
    (print (index arr (get i)))
))

Output:

1
2
4
4
5
5
6
7

Usage✍

AssistScript can be used in multiple ways. You can use it as a standalone program in the terminal using the AssistScript CLI, or you can use it inside your JavaScript code.

Using terminal💻

You can run AssistScript using the terminal. The AssistScript package comes with a command-line interface to run AssistScript files. It also has a REPL mode to run commands interactively.

# Without installing the package
npx assistscript

OR

# Once the package is installed
aslangc

The above commands, once executed, will show the help menu for the CLI.

📝 You can interchangeably use aslangc and assistscript in the terminal.

REPL mode⌨️

You can run the REPL mode by using the -r or --repl flag.

aslangc -r

File Mode📂

You can run AssistScript(.asrc) files using the CLI by providing the path to the file.

aslangc <path-to-file>

Using the API💻

You can also use AssistScript in your JavaScript code, for this AssistScript exposes a simple API. The AssistScript class is the main class that you can use run AssistScript code.

import {AssistScript} from 'assistscript';

const as = new AssistScript();

// Prints 70
console.log(as.run('add 10 20 30'));
// Prints 50 <- (100 - 20 - (10 + 20))
console.log(as.run('sub 100 20 (add 10 20)'));
