anniyan 0.1.1

MIME-type string validator

Anniyan

A fast, minimal, and IANA-compliant MIME type validator for Python.

---

✨ Features

• ✔️ Validates MIME types against official IANA registry
• ⚡ Zero runtime dependencies
• 🧠 Handles real-world inputs (; charset=utf-8, casing, etc.)
• 📦 Lightweight and fast (set-based lookup)
• 🔁 Deterministic, pre-generated data (no network at runtime)

---

📦 Installation

Local development

pip install -e /path/to/anniyan

From wheel

pip install dist/anniyan-0.1.0-py3-none-any.whl

---

🚀 Usage

from anniyan import is_valid_mime

is_valid_mime("application/json")              # True
is_valid_mime("text/html; charset=UTF-8")      # True
is_valid_mime("image/not-real")                # False

---

🧪 Behavior

• Case-insensitive
• Ignores MIME parameters (; charset=...)
• Requires valid type/subtype structure

---

🏗️ How It Works

• MIME types are fetched from the official IANA registry
• Data is normalized and compiled into Python sets
• Validation is a constant-time lookup

---

🔧 Development

Install dev dependencies:

pip install .[dev]

Run tests:

pytest

Regenerate MIME dataset:

python -m anniyan.data_generator
