Add Ctags Support for Intelligent Code Navigation 🚀

[mireklzicar]

Add support for ctags - a powerful indexing system that creates smart summaries of your entire codebase structure.

What are Ctags?

Ctags generate a structured index of your code that maps:

• Functions → their parameters, return types, and locations
• Classes → their methods, properties, and inheritance
• Variables → their types and scopes
• Modules → their exports and dependencies

Real-World Example

Instead of scanning thousands of lines, ctags provide instant access to structure like:

src/
├── api/
│   └── handlers.py:
│       class UserHandler
│         ├── __init__(self, db_connection, auth_service)
│         ├── create_user(self, user_data: dict) → User
│         ├── get_user(self, user_id: str) → Optional[User]
│         └── delete_user(self, user_id: str) → bool
│       function
│         └── validate_email(email: str) → bool
└── models/
    └── user.py:
        class User
          ├── __init__(self, id: str, email: str, name: str)
          ├── to_dict(self) → dict
          └── from_json(cls, data: dict) → User

Success Story: Aider

The Aider AI coding assistant already uses ctags extensively:

• Enables AI to work with large codebases efficiently
• Provides accurate code suggestions and refactoring
• Significantly improves AI's understanding of project structure
• See their docs

Ctags provide the perfect balance of speed, accuracy, and universal language support.
