A Python package for programmatic creation of Python virtual environments
Project description
A Python package for programmatic creation of Python virtual environments
Prerequisites
A virtualenvwrapper installation must have been installed and be available in a login shell. The following virtualenvwrapper implementations have been tested:
Possibly in future we will also support:
Shell selection
This venv-management package delegates most operations to one of the virtualenvwrapper tools listed above which are implemented using shell scripts and shell functions. In order to invoke these scripts and functions successfully the shell environment mush have been correctly configured. By default venv-management attempts to use the current user’s preferred shell by examining the $SHELL environment variable. This can be overridden by setting the $VENV_MANAGEMENT_SHELL variable with a shell executable name or the path to a shell executable, for example:
export VENV_MANAGEMENT_SHELL=zsh
If neither $SHELL nor $VENV_MANAGEMENT_SHELL are set, an attempt to use bash will be made.
Shell configuration
The selected shell must be configured to make the virtualenvwrapper commands available. By default, venv-management will source the rc file corresponding to the selected shell, for example .bashrc for bash, .zshrc for zsh, and so on, on the basis that virtualenvwrapper initialization is often performed from these files. If the rc file for the selected shell can only be usefully sources in an interactive shell, set VENV_MANAGEMENT_INTERACTIVE_SHELL to yes:
export VENV_MANAGEMENT_INTERACTIVE_SHELL=yes
Should you wish to specify a different file for shell configuration, provide its path in the VENV_MANAGEMENT_SETUP_FILEPATH environment variable. For example, since .bashrc returns immediately in non-interactive shells, and only login shells source .profile on start-up, you may want to set up both pyenv and virtualenvwrapper in a separate file, in this example called .venvwraprc:
export PYENV_ROOT=$HOME/.pyenv export PATH=$PYENV_ROOT/bin:$PATH eval "$(pyenv init -)" eval "$(pyenv init --path)" pyenv virtualenvwrapper
If the VENV_MANAGEMENT_USE_SETUP is set to yes, the script whose filepath is specified in the VENV_MANAGEMENT_SETUP_FILEPATH variable will be sourced before every command provided by this package:
export VENV_MANAGEMENT_USE_SETUP=yes export VENV_MANAGEMENT_SETUP_FILEPATH=$HOME/.venvwraprc
You can also source this custom config file in a shell-specific rc file using the source or . command, so that virtualenvwrapper could be used in interactive shells.
Manual release
Upgrade the version:
$ bumpversion <major | minor | patch>
Push the tagged commit into the repository together with the tag. You can find the latest tag using the git tag command or find and fill in the most recent tag with git describe:
$ git push --atomic origin master $(git describe --abbrev=0 --tags)
Create the source and the binary distribution (outputs in the dist directory):
$ python setup.py sdist bdist_wheel
Remove old versions in the dist directory and use the following command to upload its contents to PyPI:
$ twine upload dist/* --config-file=<path/to/file/with/credentials.pypirc>
