zetuptools

zetuptools contains a command line tool, install-directives, used to aid in post-install and post-uninstall steps for packages installed with pip. It also includes a class to represent packages installed with pip.

It originally had some other functions I considered useful in a setup.py file, but these have been scrapped as of version 3.0 as they cause too many dependecy confusions and honestly do not save that much time.

As of version 4.0, there are breaking changes regarding Docker images. You need to specify them, sorted, in the constructor of an InstallDirectives object.

Usage

The idea is to write a custom class that extends InstallDirective, overriding its package_name and module_name attributes and its _install and _uninstall functions. This should be placed in a Python package called install_directives.

These overridden functions will be called upon running the command line tool as such.

usage: install-directives [-h] [--verbose] package {install,uninstall}

positional arguments:
  package
  {install,uninstall}

optional arguments:
  -h, --help           show this help message and exit
  --verbose            be verbose

See apt-repo for a real-world example of how to use this with your Python package. Note the placement of install_directives as well as the fact that the README mentions that you should run install-directives apt-repo install after the pip package is installed.

zetuptools should be also helpful for building Docker images related to the project. There is a function called build_docker_images that will do just that. It attempts to build Docker images cleverly in the order in which they are needed to be built, but this could actually be coded wrong. Be advised. I will revisit this at some point in the future.

install-directives [package_name] uninstall should be run before the uninstallation of the pip package. Similarly, a remove_docker_images function exists.
