The more visual elements are built around the following CLI things:
- python 3 virtual environments managed with virtualenvwrapper
- tmux v2.4+
- neovim 0.3+
- bash 4+
Status integrations for:
- kubernetes
- postgres 9 (local, per-venv instances)
- terraform
neovim supports individual thread pools for managing connectivity to what are called scripting host processes in the (generic) vim world.
Scripting host processes are used to facilitate the execution of neovim plugins written in the language in question. This is in contrast to pure vim-script plugins or those written in static/compiled-to-binary languages. Currently, python2/3, ruby and nodejs are the three languages supported in this capacity.
Subsequently, nvim requires these languages supply a driver library as an API gateway.
NOTE: I played around with ruby's virtual environments without getting much
of a handle on them. Since I do very little with ruby, its driver is naively
installed using /usr/bin/gem. Just know that the same is recommended for ruby
as is for python even if not demonstrated here.
The following shows the installation of pynvim into a python2 virtualenv. It is recommended to use scripting host-specific virtual environments for the driver to run from.

This shows the installation of the ruby neovim driver:

Neovim comes with a handy built-in routine called checkhealth which
should give you something that looks like this when things are as they
should be:
