pigar is a Python CLI tool that automatically generates requirements.txt files by analyzing import statements in a project's source code, including Jupyter notebooks and dynamic imports. It can also search PyPI for distributions by top-level import name and check requirements for outdated versions.

Use cases

• generate requirements.txt from python project imports
• find which pypi package provides an import name like bs4
• check if requirements.txt dependencies are outdated
• generate requirements for jupyter notebooks
• create separate requirements files for python 2 and 3
• resolve ImportError by mapping module name to package

When to choose

• you need to bootstrap a requirements.txt for an existing codebase with no dependency file
• you want to trace imports (including dynamic ones and notebooks) to their distributions
• you need to look up the package behind an unfamiliar import name

When to avoid

• you need full dependency management with lockfiles - use pipenv, uv, or poetry instead
• you need transitive dependency resolution rather than direct import scanning
• your project relies heavily on packages not installed locally and not on PyPI
