env-printer 0.1.0

Print environment variables and recursively list files on install.

env-printer

A tiny Python package that prints all environment variables and recursively lists all files starting at a specified root (default: /). It attempts to do this automatically right after installation and also provides a CLI to trigger it manually.

Important notes about post-install behavior

• Modern Python packaging installs pre-built wheels, which typically do not execute arbitrary code at install time. This package wires a custom install command that runs after a legacy setup.py install. Depending on how the installer resolves your environment, the post-install may run during the build step rather than the final install step, or it may be skipped entirely when installing a wheel.
• To force running the legacy installation flow locally, you can install from source with:

pip install --no-binary :all: --no-use-pep517 env-printer

Even if the post-install hook does not execute, you can still run the same behavior manually via the CLI (below).

CLI usage

After installing, you can run:

env-printer-run

Options:

• --root <path>: change the starting directory for file listing (default: /).

What it does

1. Prints all environment variables as KEY=VALUE.
2. Recursively lists all files under the chosen root (default: /), skipping unreadable paths and not following symlinks.

Install locally from this repository

python setup.py sdist bdist_wheel
pip install dist/env-printer-*.whl

To exercise the legacy flow and run the post-install hook:

pip install --no-binary :all: --no-use-pep517 .
