### Install script
`install.sh` currently handles installing `Packer`, `pynvim`, `pipx` and currently configured language servers with formatters.
Will also update existing installs if already present.

### Installing `Packer` plugin manager
```bash
git clone --depth 1 https://github.com/wbthomason/packer.nvim\
 $HOME/.local/share/nvim/site/pack/packer/start/packer.nvim
```
Plugin definitions are in `plugins.lua`, inside `vim` run `:PackerSync` to install plugins

## Enabling python support
Set up neovim specific virtual environment to install `pynvim` package:
```bash
python3 -m venv "${XDG_CONFIG_HOME:-$HOME/.config}/nvim/venv"
source "${XDG_CONFIG_HOME:-$HOME/.config}/nvim/venv/bin/activate"
pip install -U pip setuptools wheel && pip install -U pynvim
source deactivate
```

### Installing language servers using `pipx`
Install [pipx](https://pypa.github.io/pipx/) in chosen manner, e.g. as given in documentation:

```bash
python3 -m pip install --user pipx
python3 -m pipx ensurepath
```

For currently configured language servers and formatters run:

```bash
pipx install pyright
pipx install fortls
pipx install black
pipx install isort
pipx install zimports
```
