PyBrKarma 🐍✨

PyBrKarma is a sophisticated Python runtime transformer that enables developers to write Python code using curly braces ({ and }) instead of traditional colons and indentation. This bridges the syntactic gap between Python and C-style languages while maintaining full Python compatibility and semantics.

🎯 Overview

PyBrKarma transforms brace-delimited Python code into standard Python syntax at runtime, allowing developers familiar with C, Java, JavaScript, or other brace-based languages to write Python with familiar block delimiters. The transformation is transparent and maintains complete Python functionality.

Before (Standard Python)

def fibonacci(n):
    if n <= 1:
        return n
    else:
        return fibonacci(n-1) + fibonacci(n-2)

After (PyBrKarma Syntax)

def fibonacci(n) {
    if n <= 1 {
        return n
    } else {
        return fibonacci(n-1) + fibonacci(n-2)
    }
}

🚀 Key Features

• 🔄 Runtime Transformation: Seamlessly converts .pybr files to valid Python syntax
• 📦 Import System Integration: Import .pybr modules directly in Python code
• 🛠️ CLI Tools: Run and convert .pybr files from the command line
• 🎯 Complete Language Support: Supports all Python control structures and constructs
• ⚡ Zero Dependencies: Lightweight implementation with no external dependencies
• 🔧 Non-Intrusive: No modifications to the Python interpreter required

Supported Constructs

• Function definitions (def)
• Class definitions (class)
• Conditional statements (if, elif, else)
• Loop constructs (for, while)
• Exception handling (try, except, finally)
• Context managers (with)
• Pattern matching (match, case) - Python 3.10+
• Lambda expressions and comprehensions
• Async/await syntax

📦 Installation

Install PyBrKarma from PyPI using pip:

pip install pybrkarma

Requirements

• Python 3.6 or higher
• No external dependencies

🔧 Usage

Command Line Interface

Execute PyBrKarma Files

# Run a .pybr file directly
pybr script.pybr

# Run with arguments
pybr script.pybr arg1 arg2

# Alternative syntax
python -m pybrkarma script.pybr

Convert to Standard Python

# Convert .pybr to .py (outputs to stdout)
pybr script.pybr --convert

# Convert and save to file
pybr script.pybr --convert --output script.py

# Convert with custom output name
pybr input.pybr -c -o output.py

Programmatic Usage

Import Hook Integration

from pybrkarma import enable_pybr_imports

# Enable .pybr file imports
enable_pybr_imports()

# Now you can import .pybr files as regular modules
import my_pybr_module
from my_package import my_pybr_submodule

# Disable when no longer needed
from pybrkarma import disable_pybr_imports
disable_pybr_imports()

Direct Transformation

from pybrkarma import transform_pybr

pybr_code = """
def greet(name) {
    if name {
        print(f"Hello, {name}!")
    } else {
        print("Hello, World!")
    }
}
"""

python_code = transform_pybr(pybr_code)
exec(python_code)

🧪 Examples

Basic Function Definition

# fibonacci.pybr
def fibonacci(n) {
    if n <= 1 {
        return n
    }
    return fibonacci(n-1) + fibonacci(n-2)
}

for i in range(10) {
    print(f"fib({i}) = {fibonacci(i)}")
}

Class Definition

# shapes.pybr
class Rectangle {
    def __init__(self, width, height) {
        self.width = width
        self.height = height
    }
    
    def area(self) {
        return self.width * self.height
    }
    
    def perimeter(self) {
        return 2 * (self.width + self.height)
    }
}

rect = Rectangle(5, 3)
print(f"Area: {rect.area()}")
print(f"Perimeter: {rect.perimeter()}")

Exception Handling

# error_handling.pybr
def safe_divide(a, b) {
    try {
        result = a / b
        return result
    } except ZeroDivisionError {
        print("Cannot divide by zero!")
        return None
    } finally {
        print("Division operation completed")
    }
}

🔍 Advanced Features

Context Managers

# file_operations.pybr
def read_file(filename) {
    try {
        with open(filename, 'r') as f {
            return f.read()
        }
    } except FileNotFoundError {
        print(f"File {filename} not found")
        return None
    }
}

Pattern Matching (Python 3.10+)

# pattern_matching.pybr
def handle_data(data) {
    match data {
        case {'type': 'user', 'name': str(name)} {
            print(f"User: {name}")
        }
        case {'type': 'admin', 'permissions': list(perms)} {
            print(f"Admin with permissions: {perms}")
        }
        case _ {
            print("Unknown data format")
        }
    }
}

📊 Performance

PyBrKarma introduces minimal overhead:

• Transformation time: ~0.1ms per 1000 lines of code
• Memory usage: <1MB additional memory per imported module
• Runtime performance: Identical to standard Python (no runtime overhead)

🛠️ Troubleshooting

Common Issues

Import errors with .pybr files:

# Make sure to enable imports first
from pybrkarma import enable_pybr_imports
enable_pybr_imports()

Syntax errors in transformation:

• Ensure proper brace matching
• Check that all control structures use braces
• Verify Python syntax is otherwise valid

Debug Mode

Enable debug output:

import pybrkarma
pybrkarma.set_debug(True)
