rl-lang — VS Code Syntax Highlighting

Syntax highlighting for rl-lang, a custom programming language built in Rust.

Features

• Syntax highlighting for .rl files
• Keywords, operators, literals, strings, and comments highlighted
• Based on TextMate grammar for broad theme compatibility

Usage

Install the extension, then open any .rl file — highlighting is applied automatically.

If VS Code doesn't detect the language, select RL manually from the language picker in the status bar.

dec int x = 10
dec string name = "rl-lang"

fn greet(string name) {
    println("Hello, ", name)
}
