Custom Shell with Autocompletion and Modern UI

Welcome to the Custom Shell project! This project implements a custom shell with autocompletion and a modern user interface using PyQt5. The shell supports both built-in commands and external executables, along with many advanced features to enhance user productivity.

Features

• Built-in Commands: Supports common shell commands like cd, pwd, echo, type, and clear.
• External Command Execution: Automatically detects and executes external executables from the user's PATH.
• Autocompletion: Offers command and path autocompletion using a Trie-based algorithm.
• Environment Variable Support: Set and export environment variables using the set and export commands.
• Command History and Search:
  • Maintains command history across sessions.
  • Navigate previous commands using the Up/Down arrow keys.
  • Search through history with Ctrl+R.
• File Redirection: Supports output and error redirection using operators such as >, 1>, 2>, >>, and 2>>.
• Relative Path Handling: Seamlessly manages relative paths (e.g., ./, ../, ~, ~/).
• Syntax Highlighting: Provides syntax highlighting for commands, paths, strings, and error messages.
• Directory Preview on Autocomplete: When a directory is uniquely completed, displays a preview of its contents.
• Modern UI & Customization:
  • Built with PyQt5 for a sleek, modern look.
  • Customize the interface by changing the font and text color.
  • Switch between Dark and Light themes for optimal viewing.

Getting Started

Prerequisites

• Python 3.x
• Pipenv
• PyQt5

Installation

1. Clone the repository:

   git clone https://github.com/Emir2099/ShellPy.git
   cd ShellPy
   
   

2. Install dependencies:

   pipenv install
   

3. Running the Shell: To run the shell locally, use the following command:

   python main.py
   

4. Usage: Once the shell is running, you can use it like a regular shell. Here are some examples of supported commands:

   Change Directory:

   $ cd /path/to/directory

   Print Working Directory:

   $ pwd

   Echo Text:

   $ echo "Hello, World!"

   Clear Screen:

   $ clear

   Type Command:

   $ type echo

   Set and Export Environment Variables:

   $ set VAR value
   $ export VAR

   Command Redirection:

   $ echo "Hello, World!" > output.txt
   

   History Search

   Ctrl + R
   

5. Customization: You can customize the shell's appearance through the settings menu:

Change Font: Select "Settings" > "Change Font" to choose a different font. Change Color: Select "Settings" > "Change Color" to choose a different text color. Themes: Switch between Dark and Light themes from the "Themes" menu.
