magicimporter 0.1.0

Smart Python import wrapper with lazy load and auto-install

🪄 magicimporter

Smart Python import wrapper that makes your imports lazier, safer, and smarter.

Written by a developer who's tired of writing try: import ... except: install ... everywhere.

🚀 What It Does

magicimporter is a tiny utility that helps you:

✅ Lazy-load modules - defer importing until first access
✅ Auto-install missing packages - no more pip install errors
✅ Avoid clutter - wrap your imports cleanly and clearly
✅ Support optional dependencies - without breaking your app

Perfect for:

• Notebooks and prototyping
• Reducing startup time (e.g., in CLI tools)
• Handling optional packages gracefully
• Plug-and-play with any Python script

📦 Installation

From PyPI (soon):

pip install magicimporter

From source:

git clone https://github.com/Deadpool2000/magicimporter
cd magicimporter
pip install -e .

🔧 How to Use

Basic Usage

from magicimporter import magic_import

json = magic_import("json")  # Just works like import
print(json.dumps({"hello": "world"}))

---

Lazy Import (delay loading until accessed)

np = magic_import("numpy", lazy=True)

# numpy isn’t imported until this line:
print(np.array([1, 2, 3]))

---

Auto-Install Missing Packages

requests = magic_import("requests", auto_install=True)

res = requests.get("https://httpbin.org/get")
print(res.status_code)

---

Lazy + Auto-Install Together

pandas = magic_import("pandas", lazy=True, auto_install=True)

# Nothing is loaded yet...
print("About to create DataFrame")

df = pandas.DataFrame({"a": [1, 2, 3]})  # Now pandas loads
print(df)

---

Import Submodules

os_path = magic_import("os.path", lazy=True)
print(os_path.basename("/foo/bar.txt"))

---

Optional Dependencies Pattern

try:
    yaml = magic_import("pyyaml", auto_install=False)
    config = yaml.safe_load(open("config.yaml"))
except ModuleNotFoundError:
    print("Skipping YAML config support: dependency missing")

🧪 Running Tests

pytest tests/

You can also test individual features manually from examples/demo.py.

🧠 Why This Exists

You're writing a script or notebook and hit this:

import somepackage  # ModuleNotFoundError

Then you type:

pip install somepackage

And do it again. And again.
What if your code just handled that?
That's what magicimporter does.

It’s especially useful when:

• Building CLI tools with optional features
• Using heavy modules only in specific branches
• Rapid prototyping in notebooks or scripts

---

📌 Notes & Caveats

• Auto-install uses subprocess to call pip - no fancy API yet.
• Lazy import doesn't delay sub-imports inside a module (standard Python behavior).
• Use responsibly in production: implicit installs may surprise your users.

---

🛠️ Roadmap Ideas

• Async import support
• Config file or env variable overrides
• Warnings and logging customization
• Module-level caching
