Monster Language for VS Code

Basic VS Code support for the Monster programming language and .mnst source files.

This extension is developed alongside the main Monster compiler project:

• Compiler: https://github.com/jwheo12/monster-lang
• Extension: https://github.com/jwheo12/monster-vscode

Install

From the VS Code Marketplace:

• https://marketplace.visualstudio.com/items?itemName=monster-lang.monster-language

Or from the command line:

code --install-extension monster-lang.monster-language

What You Get

• .mnst file association
• syntax highlighting for core Monster syntax
• line comments and bracket rules
• starter snippets for main, hello, if, and while
• Monster file icon support for themes that do not define one already

Quick Start

fn main() -> i32 {
    print_str("Hello, World!");
    return 0;
}

Open a .mnst file and VS Code will automatically switch to Monster language mode.
