The Hook Programming Language

Hook is a simple, cross-platform, dynamically typed scripting language that utilizes a mutable value semantics approach. It was developed from scratch using C and employs clear and simple techniques such as recursive descent parsing, stack-based virtual machine, and reference counting.

Note: Hook is currently in the early stages of development and should not be used in production environments at this time.

What does it look like?

Hook features a modern syntax similar to C.

fn factorial(n) {
  if (n == 0)
    return 1;
  return n * factorial(n - 1);
}

Features

Hook offers the following key features:

• Imperative and functional programming paradigms
• Cross-platform compatibility
• Dynamic typing
• Mutable value semantics approach
• Familiar C-like syntax
• Support for value-captured closures

Installing

The following command can be used to install Hook on Linux (x64) and macOS (x64, arm64) systems:

curl -sSL https://raw.githubusercontent.com/hook-lang/hook/main/scripts/install.sh | sh

For Windows (x64) users, open a terminal and use the following commands:

cd %tmp%
curl -sSLO https://raw.githubusercontent.com/hook-lang/hook/main/scripts/install.bat
install

Installing with Homebrew

If you're a macOS user, you can also install Hook using Homebrew:

brew tap hook-lang/hook
brew install hook

Note: Follow the instructions provided by Homebrew to add the HOOK_HOME environment variable to your system.

Building from the source code

If you prefer, you can also build Hook locally by following the instructions provided in BUILDING.md.

Hello, world!

You can run the classic Hello, World! program directly from the terminal by using the following command:

hook -e 'println("Hello, world!");'

Documentation

Unfortunately, as the language undergoes constant breaking changes, it's impractical to have complete documentation. However, we have some text files and examples that can help:

• docs/grammar.md
• docs/built-in.md
• docs/core-modules.md
• examples

Additionally, we have a cheatsheet that can be accessed at: https://cheatsheets.zip/hook

Play with Hook online

Get hands-on with Hook by visiting the Hook Playground. You can easily write and run Hook code directly from your browser, whether it be from the provided examples or the code you've been itching to try.

Editor Support

Hook offers an extension for the popular code editor, Visual Studio Code. This extension provides features such as syntax highlighting, code completion, and code snippets, making your development experience more efficient. The extension can be easily installed from the Visual Studio Marketplace.
