installcheck 0.1.0

CLI tool to check Python import dependencies in .py files

🧪 installcheck

Check which Python modules your project actually needs – line by line.

---

🚀 What is this?

installcheck is a CLI tool that scans your Python codebase,
parses every import statement, and checks whether those modules are actually available in your environment.

It helps you:

• Identify missing dependencies 🧩
• Clean up broken or unused imports 🧹
• Write better CI/CD checks 🛠
• Know exactly what you need to pip install 📦

---

📦 Installation

pip install installcheck

Or for development:

git clone https://github.com/seong-hun/installcheck.git
cd installcheck
pip install -e .

---

⚙️ Usage

installcheck ./your_project              # summary mode
installcheck ./your_project --verbose   # line-by-line failure details

---

🧪 Example Output

✅ All Good

✅ All imports succeeded!

❌ Failures Detected (with –verbose)

❌ Import Failures Detected:

src/foo.py:
  [12] from torch.nn import Linear
      → ModuleNotFoundError: No module named 'torch'

  [30] import non_existent_lib
      → ModuleNotFoundError: No module named 'non_existent_lib'

Total failed imports: 2 in 1 files

📦 Missing modules you might need to install:
   pip install torch non_existent_lib

✨ Features

•	✅ Scans all .py files recursively
•	✅ Ignores virtualenvs and hidden/system folders
•	✅ Parses actual import statements via ast
•	✅ Reports:
•	Which files fail
•	Which import lines fail (with --verbose)
•	Which modules are missing (pip install ...)
•	✅ Multiprocessing for speed ⚡

---

💡 Why?

Because ModuleNotFoundError should never be a surprise in CI. And because import foo might look innocent… until it silently fails 😅
