`pyvenv-extras`

An Emacs package that adds projectile and/or persp-mode-based Python virtual environment tracking to pyvenv, and more.

Features

`pyvenv-extras-mode`

Initialize terminals so that they automatically enable the local venv (implemented for term and vterm)
Add CONDA_PREFIX and CONDA_DEFAULT_ENV variables to the environment
Activate comint buffers within the projectile-determined project root directory
Start and restart Python inferior processes in a way that preserves the pyvenv venv settings and prevents the cursor from jumping
Make interactive Python sessions project-specific by adding projectile project names to python-mode process names
Make flycheck use the projectile project directory

`pyvenv-projectile-tracking-mode`

This mode augments pyvenv-tracking-mode by only changing the virtual environment when the projectile project changes (and has a different virtual environment).

Currently, the approach used relies on the availability of pyvenv-workon values within in each projects’ .dir-locals.el, so each project must have those set.

`pyvenv-persp-tracking-mode`

This mode sets the virtual environment when a persp-mode perspective is activated.

When projectile is set to use persp-mode-scoped projects via =proj-persp-extras= and pyvenv-projectile-tracking-mode is enabled, this mode effectively enables persp-mode-based virtual environment scopes. In other words, your current persp-mode perspective determines which virtual environment is activate.

Usage

Just enable the minor modes:

(pyvenv-extras-mode +1)
(pyvenv-projectile-tracking-mode +1)
(pyvenv-persp-tracking-mode +1)
