Somewhere between pip and pipsi

"pipis" stands for "pip isolate"
and "pipi" is the french for "peepee" which is a fun name but pipi was already taken…

Actually it is a rewrite of pipsi but with venv instead of virtualenv.
What does it do?
Pipis is a wrapper around venv and pip which installs scripts provided by python packages into separate venvs to shield them from your system and each other.
It creates a venv in ~/.local/share/pipis/venvs/, update pip, installs the package, and links the package's scripts to ~/.local/share/pipis/bin/. These directory can be changed respectively through the environment variables PIPIS_VENVS and PIPIS_BIN.
Why not pipsi?
Because i do not care about Python 2, and virtualenv copies python's binaries while venv just symlink them (which i think is cleaner, but it still copies pip which is not clean…).
How to install
Automatic
Coming soon…
Manual
Create the pipis venvs and bin directories:
mkdir -p ~/.local/share/pipis/{venvs,bin}

Create and activate the pipis virtual environment:
python3 -m venv ~/.local/share/pipis/venvs/pipis
source ~/.local/share/pipis/venvs/pipis/bin/activate

Upgrade the pip package:
pip install -U pip

Install pipis:
pip install pipis

Exit the virtual environment:
deactivate

Link the pipis script into the "global" bin directory:
ln -s ~/.local/share/pipis/venvs/pipis/bin/pipis ~/.local/share/pipis/bin/

Add the pipis "global" bin directory to your PATH:
export PATH="~/.local/share/pipis/bin:${PATH}"

How to update
pipis update pipis

How to uninstall
pipis uninstall pipis

How to use
Show help
$ pipis -h
usage: pipis [-h] [-v] {version,freeze,search,install,update,uninstall} ...

Pipis installs Python packages into their own dedicated virtualenv to shield
them from your system and from each other. Virtualenvs are created in
`PIPIS_VENVS` (default: `~/.local/share/pipis/<package>`) and links the
scripts to `PIPIS_BIN` (default: `~/.local/share/pipis/bin/`).

optional arguments:
-h, --help show this help message and exit
-v, --verbose enable verbose ouput

available commands:
{version,freeze,search,install,update,uninstall}
version show pipis version
freeze output installed packages in requirements format
search search for PyPI packages whose name or summary
contains <query>
install install packages
update update packages
uninstall uninstall packages

You can also invoke --help on each commands.
