# My `neovim` setup

I'm trying to document my neovim setup. Mostly, I'm using neovim to edit
markdown, HTML, CSS/SCSS and python files.

I'm using `vim-plug` as a plugin manager. To install and activate `vim-plug`
see the [documentation][7].

## To do

- [x] Document how to use `pyenv` to provide a python engine.
- [x] Identify the python package dependencies.

## Requirements

1. `neovim`
1. `git`
1. A python virtualenv with python dependencies installed. (see [pyenv
   section][10]).
1. `nodejs`, `yarn`
1. [vim-plug][1]
1. [ripgrep][2]
1. [The Silver Searcher (`ag`)][3]
1. A [font patched for nerds][8].

## Installation

1. Check [the requirements][4]. ⬆
1. Clone the repository \
   `git clone <URL>`
1. Create a symlink: \
   `ln /path/neovim/init.vim /home/user/.config/nvim/init.vim`.
1. [Install `vim-plug`][7].
1. Start `neovim`.
1. Install the plugins (`:PlugInstall`).

## Create a virtualenv with pyenv

Benefit: having a separate virtual environment for the python engine than the
one your working into.

Install `pyenv` with the [`pyenv-installer`][9].

Install the python version you need with `pyenv`:

```bash
pyenv install <python version> 
```

Create and name the virtual environment for neovim:

```bash
pyenv virtualenv <python version> neovim
```

Activate the virtual environment and fetch the python path:

```bash
pyenv activate neovim
pyenv which python      # Note the provided path
```

Add the following line to your `init.vim`:

```init.vim
let g:python3_host_prog = '/full/path/to/neovim/bin/python
```

Install the python dependencies in the virtual environment as it is activated:

```bash
pip install -r requirements.txt 
```

To deactivate the virtual environment:

```bash
pyenv deactivate
```
