    मुद्रण("अल्पवयीन")
}

While Loop

चल i = १
जोपर्यंत i <= ५ {
    मुद्रण("संख्या:", i)
    i = i + १
}

For-Each Loop

चल यादी = [१, २, ३, ४, ५]
प्रत्येक item मध्ये यादी {
    मुद्रण("आयटम:", item)
}

Operators

• + (addition)
• - (subtraction)
• * (multiplication)
• / (division)
• % (modulo)

Comparison

• == (equal)
• != (not equal)
• < (less than)
• > (greater than)
• <= (less than or equal)
• >= (greater than or equal)

Logical

• आणि (and)
• किंवा (or)
• नाही (not)

Fibonacci Sequence

कार्य फिबो(n) {
    जर n <= १ {
        परत n
    }
    परत फिबो(n - १) + फिबो(n - २)
}

चल परिणाम = फिबो(८)
मुद्रण("फिबोनाची संख्या:", परिणाम)

Factorial

कार्य फॅक्टोरियल(n) {
    जर n <= १ {
        परत १
    }
    परत n * फॅक्टोरियल(n - १)
}

मुद्रण("फॅक्टोरियल:", फॅक्टोरियल(५))

Array Operations

चल यादी = [१, २, ३, ४, ५]
मुद्रण("यादी:", यादी)
मुद्रण("पहिला element:", यादी[०])

प्रत्येक num मध्ये यादी {
    मुद्रण("संख्या:", num)
}

• Code Editor: Syntax-highlighted text editor
• Run Code: Execute Marathi programs with F5 or Run button
• File Operations: New, Open, Save files
• Output Display: Shows program output and errors
• Status Bar: Shows current operation status
• Keyboard Shortcuts:
  • F5 or Ctrl+R: Run code
  • Ctrl+N: New file
  • Ctrl+O: Open file
  • Ctrl+S: Save file

REPL Commands

When running in REPL mode:

• मदत or help: Show help
• बाहेर or exit: Exit REPL
• इतिहास: Show command history
• चल: Show variables
• दस्त: Show documentation
• उदाहरण [topic]: Show examples

Error Handling

The interpreter provides error messages in both Marathi and English:

• Syntax errors show line and column information
• Runtime errors provide descriptive messages
• Unicode encoding issues are handled automatically

Contributing

1. Fork the repository
2. Create a feature branch
3. Make your changes
4. Add tests for new features
5. Submit a pull request

Troubleshooting

Unicode Issues on Windows

If you encounter Unicode display issues:

1. Use run_marathi.py instead of main.py
2. Ensure your console supports UTF-8
3. The IDE handles Unicode automatically

Common Issues

• File not found: Ensure the file path is correct and the file exists
• Syntax errors: Check for proper Marathi keywords and syntax
• Runtime errors: Verify variable declarations and function calls

Future Enhancements

• VS Code extension for syntax highlighting
• More comprehensive standard library
• Package management system
• Advanced debugging features
• Web-based IDE
• Mobile app support
