# Neovim Configuration

![screenshot](screenshot.png)

This is V2 of my Vim configuration, designed for Neovim, broken out into
it's own repository for easier cloning without pulling down the entire
`essentials` repository.

I use the `nord` theme for both my terminal and Vim. You will need to adjust your theme and
airline according to your tastes in `plugins.vim` and `ui.vim`.

The V2 repo aims to take full advantage of asynchronous code and a modularized configuration to make
adaptation easier and the UI snappier. Additionally support for `tmux` has improved with this iteration
through the use of `vimux` and `vim-tmux-navigator`.

## Requirements

1. [Neovim](https://github.com/neovim/neovim)
2. [vim-plug](https://github.com/junegunn/vim-plug) - You may need to install this even with the `autoload` directory.
3. [Monospaced Nerd Font](https://www.nerdfonts.com/font-downloads) - The `/font` directory has one I use.
4. `tmux`

## Updating

After running `git pull` you may need to run `:PlugInstall` and restart neovim to resolve any errors.

For Python editing:

1. [Neovim](https://github.com/neovim/neovim) compiled with Python support.
2. Python
3. `pip install neovim && pip3 install neovim` in your global environment.

## Structure

* `conf`: Contains all configuration related files.
  * `plugins.vim`: General plugin definitions.
  * `keybinds.vim`: General keybinds such as leader key, etc.
  * `config.vim`: Dumping ground for general configurations.
  * `ui.vim`: General UI configurations.
  * `search.vim`: Search configurations (for example ctrl-p).
  * `git.vim`: Fugitive configurations.
  * `langs`: Language specific configurations and keybinds.

## Installation

```bash
cd .config
git clone git@git.xchg.sh:angrygoats/vim-config nvim
```

If you have added/changed plugins remember to `:PlugInstall` after saving. There currently
is no autodetect on a changed `plugin.vim`.

If you run into problems with pyenv on first start, insure that pyenv is installed and your pyenv
has at least one installation available. For example, run `pyenv install 3.9.1`.

## Language Support

Languages supported can be found in the `conf/langs` directory. To add more languages you can
create a file in the same form as those found in `conf/langs/` and place it in the `conf/langs/` folder.
It will be autoloaded.

The current loading script for languages does not check order before loading (so files can be loaded in
any order based on directory structure). However, if you followed the structure and put all your configs
in the correct files, those will be loaded *BEFORE* the languages and so you shouldn't run into (too many)
order issues. This may be patched in the future.

### Python

Pyenv support is added via [vim-pyenv](http://github.com/lambdalisue/vim-pyenv). `:PyenvActivate` can be used to
activate a given environment.

The file `conf/langs/python.vim` contains formatting code typical of a Python project (4 space indents, etc). If you
wish to adjust this you can do that here, or make modifications on a per-project basis.

## Other Notes

### Help

You can type `:help <name_of_package>` (for example `:help vim-pyenv`) to read the documentation.

### Tmux Navigation

With Tmux activated you can use

```
<ctrl-h> => Left
<ctrl-j> => Down
<ctrl-k> => Up
<ctrl-l> => Right
<ctrl-\> => Previous split
```

To move seamlessly between splits.

### Autocompletion

Autocompletion is provided by [asyncomplete.vim](https://github.com/prabirshrestha/asyncomplete.vim). Additionally
LSP-based autocompletion is installed.

### Default Leader

The default leader is the space key.

### Git

`vim-fugitive` is installed. Bindings can be found in `conf/keybinds.vim` and documentation can be found
[here](https://github.com/tpope/vim-fugitive).

The following binds are set to help development:

```
nnoremap <Leader>gs :Git<CR>
nnoremap <Leader>gd :Git diff<CR>
nnoremap <Leader>gb :Git blame<CR>
nnoremap <Leader>gc :Git commit<CR>
nnoremap <Leader>gp :Git push<CR>
```

### LSP

`vim-lsp` is installed with `vim-lsp-settings`. While editing a file that has a supported LSP server
you can type `LspInstallServer` to install the associated server. You can uninstall a server with
`:LspUninstallServer server-name`. You many need to restart your vim instance once the server is installed
to activate the LSP support.

### Org Mode

`vim-orgmode` is installed. The usage documentation can be found [here](https://github.com/jceb/vim-orgmode/blob/master/doc/orgguide.txt).

### Async Command Line

[Asyncrun.vim](https://github.com/skywind3000/asyncrun.vim) is installed. You can use this to run shell commands asynchronously.
To do this type `:AsyncRun <command>`.
