# Neovim configuration
This folder contains a Neovim editor configuration.
## Structure
The configuration consists of a main Lua configuration file `init.lua`, this
`README.md` and a `pack` folder with Neovim packages from third parties.
```
.
├── init.lua
├── pack
│ ├── <vendor> // <vendor> can be selected arbitrarily
│ │ └── start
│ │ └── <package> // Git submodule, could be one of many in this folder
└── README.md
```
All packages are Git submodules and contain third party code to extend the
editor.
## Installation
This configuration requires the following software to be installed:
- Neovim in a recent version
- Ripgrep
- Language Server Protocol Servers
- clangd
- pyright
- gopls
### Neovim
This configuration requires a recent version of Neovim and was tested with
version `v0.9.5`. If only older versions are provided by the distribution a
newer version can be installed as AppImage.
```
mkdir -p ~/.local/bin
curl https://github.com/neovim/neovim/releases/download/v0.9.5/nvim.appimage \
> ~/.local/bin/nvim
chmod 755 ~/.local/bin/nvim
PATH=~/.local/bin:$PATH # add this line to shell config (e.g. .bashrc)
# to be permanent
```
`which` can be used to validate that the current shell uses the just downloaded
AppImage.
```
$ which nvim
/home/<user>/.local/bin/nvim
```
The Neovim version can be checked with `nvim` itself.
```
$ nvim --version
NVIM v0.9.5
Build type: Release
LuaJIT 2.1.1702233742
System-vimrc-Datei: "$VIM/sysinit.vim"
Voreinstellung für $VIM: "/usr/share/nvim"
Run :checkhealth for more info
```
### Ripgrep
The program Ripgrep or `rg` is required for this configuration to work. It can
be installed on most Linux distributions using the package manager:
- Arch Linux: `pacman -S ripgrep`
- Debian Linux: `apt install ripgrep`
Ripgrep is used for the package `telescope` to search for keywords with good
performance even in huge file trees.
### LSP Servers
The LSP servers can be installed with the package manager too:
- Arch Linux: `pacman -S clang pyright gopls`
- Debian Linux: `apt install clangd gopls`
**Note for Debian**: `pyright` is not available. But the Debian package
`python3-pylsp` works too. `pyright` has to be replaced by `pylsp` in
`init.lua`.
