rshell

A lightweight command-line shell written in Rust.

Features

• Command Execution: Run system binaries and external programs.
• Built-in Commands: Includes native support for cd, pwd, and exit.
• Dynamic Prompt: Displays the current working directory.
• Git Integration: Automatically detects and displays the current Git branch in the prompt with color coding.
• Input Parsing: Handles basic tokenization of commands and arguments.

Project Structure

The project is organized into modular components:

• main.rs: The core REPL (Read-Eval-Print Loop) and execution logic.
• parser.rs: Logic for splitting input strings into executable commands and arguments.
• logging.rs: Internal utility for formatted output and error handling.
• tests.rs: Suite for verifying shell functionality.

Installation

Ensure you have the Rust toolchain installed, then clone the repository and build:

cargo build --release

Usage

Run the shell directly using cargo:

cargo run

Once inside, you will see a prompt showing your path and Git branch:

/home/user/project master ❯ ls -l
