🦀 rusty_repl

A lightweight, modular framework for building interactive REPLs in Rust — with clean prompts, terminal isolation, and customizable input handling.

✨ Features

🖥️ Alternate screen mode — clean, isolated terminal workspace
💬 Custom prompts — easily define your own Prompt style
⚡ Input handling loop — powered by reedline
🧹 Automatic cleanup — restores cursor, title, and screen on exit
🎨 Extensible design — plug in custom keyword highlighters or prompt logic

🚀 Quick Start

Add to your Cargo.toml:

[dependencies]
rusty_repl = "0.1.0"

Then in your project:

use rusty_repl::Repl;

fn handle_input(line: String) -> bool {
    if line.trim() == "exit" {
        return true;
    }
    println!("You typed: {line}");
    false
}

fn main() -> std::io::Result<()> {
    let repl = Repl::new("Demo REPL", None);
    repl.run(handle_input)
}

This opens an alternate terminal screen with a minimal prompt.

Type exit to leave the session.

🧩 Architecture

Module	Responsibility
`repl::input`	Handles user input with `reedline`
`repl::output`	Manages terminal (alternate screen, cursor, cleanup)
`repl::prompt`	Defines a cleaner, customizable prompt
`repl::manager`	Connects all components into a cohesive REPL session

Top-level entrypoint:

use rusty_repl::Repl;
