Pipenv is an experimental project that aims to bring the best of all packaging worlds to the Python world. It harnesses Pipfile, pip, and virtualenv into one single toolchain. It features very pretty terminal colors.
It automatically creates and manages a virtualenv for your projects, as well as adds/removes packages from your Pipfile as you install/uninstall packages. The lock command generates a lockfile (Pipfile.lock).
The main commands are install, uninstall, and lock, which generates a Pipfile.lock. These are intended to replace $ pip install usage, as well as manual virtualenv management (to activate a virtualenv, run $ pipenv shell).
Set _PIPENV_COMPLETE and then source the output of the program. For example, with fish, put this in your ~/.config/fish/completions/pipenv.fish:
eval (env _PIPENV_COMPLETE=source-fish pipenv)
Magic shell completions are now enabled!
