A-SHELL

A-SHELL is a custom-built POSIX-compliant shell created with the help of CodeCrafters. This project is part of the "Build Your Own Shell" Challenge, and it aims to provide a robust foundation for a shell capable of running external programs as well as handling built-in commands.

Features

• REPL (Read-Eval-Print Loop): An interactive shell interface to enter commands.
• Basic Commands:
  • echo (including support for quoting)
  • exit
  • type
  • cd
  • Error Handling: Gracefully handles errors with informative messages.
  • Redirection: Supports redirection of both stdout and stderr.
• Tab Completion:
  • Currently a work in progress – the goal is to implement tab completion using rustyline, similar to how readline works in C.

Getting Started

1. Prerequisites:

   • Ensure you have Rust installed (tested with cargo 1.82).

2. Running the Shell:

   • Use the provided shell script to compile and run the project:

     ./your_program.sh

   • The first run may be slow as the project compiles, but subsequent runs will be faster.

Next Steps

This shell is a work in progress and further stages will include additional features and improvements. Stay tuned for:

• Enhanced tab completion
• Extended built-in command support
• More robust error handling and feature enhancements
