Neovim Configuration

Setting Up Neovim for Python/C/C++ Development

Neovim is a powerful, modernized fork of Vim that is designed for developers who want a lightweight, yet extensible text editor. Its speed, versatility, and rich plugin ecosystem make it an excellent choice for Python development. In this blog post, we'll walk through the steps to set up Neovim for a seamless Python development experience.

Getting Started

First, we need to get the latest stable version of Neovim (currently 0.10.0). We can also install it using the system package manager (apt/yum/zypper) install neovim or we can get it from GitHub.

mkdir -p ~/.local/bin/
cd ~/.local/bin
wget https://github.com/neovim/neovim/releases/download/v0.11.0/nvim-linux-x86_64.appimage
mv nvim.appimage nvim
chmod +x nvim
export PATH=$PATH:~/.local/bin #  add ~/.local/bin to your PATH . Add this line to your ~/.bashrc 

Dependencies

To add support for many of the Language Server Protocol (LSP) features, i.e., Formatting, Code action, goto documentation, we need a few packages that add this functionality. Programming languages that I use:

Language	Package	How to Install
C/C++	clangd	(apt/yum/dnf/zypper) install clangd
Lua	lua_ls	https://luals.github.io/#neovim-install
Bash	bashls	https://github.com/bash-lsp/bash-language-server
Vim Script	vimls	https://github.com/iamcco/vim-language-server
Python	pylsp	pip install python-lsp-server[all]
CMake	cmake	pip install cmake-language-server
Latex	texlab	https://github.com/latex-lsp/texlab
Text	textls	https://github.com/hangyav/textLSP

Debian / Ubuntu

``` bash 
    apt install clangd vim git cmake python3-venv luarocks tree-sitter-dev  fd-find ripgrep gdb ninja-build
```

List of Neovim Plugins

There are thousands of Neovim plugins available on GitHub. Only use the ones that you need. Here are the plugins that I use.

Install this config

1. Clone the repo

   cd ~/.config/
   git clone https://github.com/srbhp/nvim.git

2. Install Plugins

   Launch Neovim and run the following command to install the plugins:

   :Lazy

3. Install coq_nvim dependencies: This needs the python3-venv package to be installed.

    :COQdeps

4. Check Neovim Health

   :checkhealth

   This will give you the current status of Neovim and report if there are any missing dependencies.

Development Container

To set up a development environment using a devcontainer, follow these steps:

1. Ensure you have Docker installed on your machine.
2. Open the project in a container using Visual Studio Code.
3. When prompted, select "Reopen in Container".

This will set up the development environment with all necessary dependencies and tools.
