Its niche is small Python programs: the authoring model is to invoke a script through fades, mark dependencies inline, in requirements files, docstrings, or command-line options, and let the tool build the environment before execution. ### Project history The public project history visible in the official GitHub releases starts with 1.0 and 2.0 tags and continues through major releases such as v4, v6, v7, v8, and v9. The README presents the central design unchanged across that line: fades creates or reuses a virtual environment, installs dependencies, then runs the child script or opens an interpreter inside that environment. ### Adoption history fades has remained a specialist Python-packaging utility rather than a mainstream workflow manager. Its official materials show packaging and distribution across PyPI, Read the Docs, Snap/AppVeyor-era CI badges, and Debian/Ubuntu guidance, while the Homebrew formula gives macOS command-line users another route to install it. ### How it is used Typical usage is `fades myscript.py`, often paired with a `#!/usr/bin/env fades` shebang. Dependencies can be marked next to imports with `# fades`, supplied with `--dependency`, read from requirement files, or listed in a docstring section, after which fades chooses or creates the matching virtual environment. ### Why package nerds care For package-manager users, fades is an example of a pre-`uv` and pre-modern-tooling answer to one-off Python script isolation. It sits between raw `virtualenv`, `pip`, and full project tools: a small executable whose point is making transient script environments feel automatic. ### Timeline - 2015: Official GitHub releases include 1.0 and 2.0-era tags. - 2017: v6 release published. - 2018: v7 release published. - 2019: v8.1 release published. - 2020: v9.0 and v9.0.1 releases published. ### Related projects - virtualenv, pip, requirements.txt workflows, pipx, pip-run, uv ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
