vibethon 1.0.1

Automatic Python Debugger with LLM-powered Interactive REPL

Vibethon - Automatic Python Debugger 🐍✨

Vibethon is an enhanced Python debugger that automatically instruments your code to provide interactive debugging capabilities whenever errors occur. No more adding breakpoint() calls or struggling with complex debugger setups!

🌟 Features

• 🔧 Automatic Function Instrumentation: All functions are automatically wrapped with error handling as they're defined or imported
• 🎯 Interactive REPL: When errors occur, you get an interactive debugging session right in the error context
• 🚀 Runtime Instrumentation: Functions are instrumented dynamically as modules are loaded
• ➡️ Continue Execution: Fix issues and continue execution from the error point
• 🔗 Compatible: Works transparently with any existing Python script or module
• 🎮 User-Friendly: Simple command-line interface, just like running python but with superpowers

📦 Installation

Option 1: Install from source (recommended for development)

# Clone or navigate to the vibethon directory
cd /path/to/vibethon

# Create and activate a virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

# Install in development mode
pip install -e .

# Or install normally
pip install .

Option 2: Direct usage (without installation)

You can also run vibethon directly after setting up dependencies:

# Create and activate a virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

# Run directly
python vibethon_cli.py script.py

Option 3: Development with Cursor DevContainer (Recommended for contributors)

This project includes a pre-configured devcontainer for seamless development in Cursor:

1. Open in Cursor: Open the vibethon directory in Cursor
2. Reopen in Container: When prompted, click "Reopen in Container" or use Cmd/Ctrl + Shift + P and select "Dev Containers: Reopen in Container"
3. Automatic Setup: The devcontainer will automatically:
   • Install Python and all dependencies
   • Set up the virtual environment
   • Install the package in development mode
   • Configure the development environment

Benefits of using the devcontainer:

• Consistent development environment across all contributors
• No need to manually manage Python versions or dependencies
• Pre-configured debugging and linting tools
• Isolated environment that doesn't affect your system Python installation

To use Vibethon in the devcontainer:

# The environment is already set up, just run:
vibethon script.py

# Or for development:
python vibethon_cli.py script.py

🚀 Usage

Once installed, you can use the vibethon command just like you would use python:

# Run a Python script with automatic debugging
vibethon script.py

# Run with command-line arguments
vibethon my_script.py arg1 arg2 --flag

# Run a Python module
vibethon -m my_package.my_module

# Execute Python code directly
vibethon -c "print('Hello from Vibethon!')"

🎮 Interactive Debugging

When an error occurs in your code, Vibethon automatically starts an interactive debugging session:

🐛 ERROR DETECTED: ZeroDivisionError: division by zero
==================================================
Traceback:
  File "test_script.py", line 28, in divide_numbers
    result = a / b

🔍 DEBUG REPL - You are now in the scope where ZeroDivisionError occurred
Available commands:
  - Type any Python expression to evaluate it
  - Use 'locals()' to see local variables
  - Use 'globals()' to see global variables
  - Type 'continue <value>' to continue execution with a return value
  - Type 'continue' to continue execution with None
  - Type 'quit' or 'exit' to exit the debugger
  - Type 'vars' to see current local variables

Current local variables:
  a = 10
  b = 0

debug> 

Debugging Commands

In the debug REPL, you can:

• Inspect variables: print(my_variable) or just my_variable
• Modify variables: my_variable = new_value
• See all local variables: vars
• Run any Python code: Execute any valid Python expression or statement
• Continue execution: continue or continue some_return_value
• Exit debugger: quit, exit, or q

Example Debugging Session

debug> vars
Local variables:
  a = 10  
  b = 0

debug> b = 1  # Fix the problematic variable
debug> a / b  # Test the fix
→ 10.0

debug> continue a / b  # Continue execution with the corrected result
Continuing execution by setting return value: 10.0

📝 Example

Here's a simple example to try:

test_example.py:

def problematic_function():
    numbers = [1, 2, 3]
    result = numbers[10]  # This will cause an IndexError
    return result

def main():
    print("Starting the program...")
    value = problematic_function()
    print(f"Got value: {value}")

if __name__ == "__main__":
    main()

Run it with Vibethon:

vibethon test_example.py

When the IndexError occurs, you'll be dropped into a debug session where you can:

• Inspect the numbers list
• Fix the index or modify the list
• Continue execution with a proper value

🔧 How It Works

1. Import Hook: Vibethon installs a custom import hook that automatically instruments functions as modules are loaded
2. AST Transformation: Each function's body is wrapped in try/catch blocks that preserve original line numbers
3. Error Interception: When errors occur, instead of crashing, you get an interactive REPL in the error context
4. Scope Preservation: The debug session has access to all local and global variables at the point of failure

🎯 Advanced Usage

Multiple Frame Selection

When errors occur in nested function calls, Vibethon lets you choose which frame to debug:

Multiple frames available:
  0: test_script.py:45 in main
  1: test_script.py:32 in process_data  
  2: test_script.py:28 in divide_numbers
Select frame (0-2, or press Enter for innermost):

Continuing with Values

You can continue execution and provide return values for failed functions:

debug> continue 42  # The function will return 42 instead of failing
debug> continue [1, 2, 3]  # Return a list
debug> continue {"status": "fixed"}  # Return a dictionary

🐛 Troubleshooting

Common Issues

1. Import errors: Make sure vibezz.py is in the same directory as vibethon_cli.py
2. Permission errors: You may need to use pip install --user . for user-only installation
3. Python version: Requires Python 3.6 or later

Getting Help

If you encounter issues:

1. Check that all files are in the correct location
2. Try running with python -v vibethon_cli.py script.py for verbose output
3. Make sure your script works normally with python script.py first
