python-transmute | idea behind this module is to support self

python-transmute is a Python library. python-transmute has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can install using 'pip install python-transmute' or download it from GitHub, PyPI.

The idea behind this module is to support self-updating Python applications, namely command-line tools. Transmute probes remote repositories for updated components, fetches updates and adds them to sys.path, making them available for use in the application. Components are assumed to be standard Python Eggs. Repositories are then simple containers for these eggs. Currently PyPI and S3 "folders" are supported as repositories. (Mostly for testing purposes, local directories are also supported as repositories). Under the hood, pkg_resources (from setuptools) is used to parse and fulfill requirements, based on listings of available eggs obtained from each repository. Once updated packages are made available, their modules can be imported or the application can be re-launched with an adjusted environment to pick up updated modules. The application writer controls the packages to update, repositories each package will be grabbed from, and when an update is actioned. The philosophy has been that an absent or flaky network should not prevent (or significantly delay) an application from running on top of outdated packages, if they've been cached locally. That said, there are currently no provisions for testing and verifying a successful update or rolling back a failed update.
