It's designed for scenarios where credentials or other sensitive configuration must be scoped to a short lifetime\u2014common in testing and in applications that receive secrets via environment variables. The package provides a simple `with TemporaryEnvironment({...})` block that accepts a dictionary of variable names to values; setting a value to `None` unsets the variable. It can optionally warn if code inside the block modifies one of the temporary variables, and can be configured to either restore the original value or leave the modified value in place.\n\nThe package has no runtime dependencies, installs as a pure Python wheel, and supports Python 3.9 through 3.13. It can be used as a context manager in regular code or as a decorator on test methods. The main use case is isolating credential or configuration changes to a specific code scope, ensuring they don't leak into the broader process environment.","worth_installing":"Yes, if you need scoped environment variable management in tests or credential-sensitive code. The package is stable, has no dependencies, and solves a real problem cleanly. The aging maintenance status (509 days since last release) is not a blocker for a simple, focused tool\u2014check whether the code already handles your Python version and use case before adopting."},"id":"tempenv","links":{"html":"https://skillfed.io/packages/tempenv","md":"https://skillfed.io/packages/tempenv.md","pypi":"https://pypi.org/project/tempenv/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-03-23","license_spdx":null,"license_treatment":"permissive","name":"tempenv","python_support":"supports_current","summary":"Environment Variable Context Manager"},"popularity":{"monthly_downloads":181869,"position":10111,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.1.0"}
