Venv Utils

This is a single script that began as some aliases to ease pain working with virtual environments when I decided to ditch Pycharm for Vim. Soon my needs became such that an aliased command was not enough and made them into functions. Later I discovered virtualenvwrapper, thought about using it but my need were already satisfied with these functions (also making your own tools feel very very nice!).

Installation

Clone the repo, call sudo make or sudo make install and the commands should be copied to your path. Additionally you should create an alias for actenv wherever you this way: alias actenv='source actenv' to make it work as intended.

Contents

The commands included here are the following:

• actenv
• createnv
• installreqs
• deletenv

Workflow

You can control where the virtual environments and the enviroment variables are stored using $VENV_DIR and $VENV_ENVAR_DIR respectively. The default directories are ~/.venvs and ~/.env_vars.

1. Use createnv inside your project folder to create a virtualenv inside the directory specified in $VENV_DIR, this also will create onact and onexit files inside the $VENV_ENVAR_DIR folder (onact should contain declarations of project specific environment variables and onexit should unset them). To select a custom python executable call it with the flag -p, it defaults to use python3. e.g. createnv -p python36, To create a virtual environment with a custom name (not the name of the current folder) call it with the flag -d. e.g. createnv -d somenvironment.
2. Use actenv to activate the virtualenv in $VENV_DIR with the name of the project. Passing it one argument will activate the virtual environment with that name instead.
3. Use installreqs to install requirements.txt if any on the current folder. It will not detect if an environment is active, be aware of that.
4. If needed use deletenv to remove a virtual environment and its environment variables.
