NVIM config

Description

This repository contains personal Neovim and Vim configuration files. It provides two different Neovim configurations:

1. init.vim (Vundle-based): Traditional Vim configuration using Vundle plugin manager
2. init.lua (Lazy.nvim-based): Modern Lua-based configuration using lazy.nvim plugin manager

The configurations are optimized for C/C++/CUDA development with support for various other languages.

Pre-requisites

Linux

sudo apt-get install -y neovim git luarocks

For full functionality, also install:

# For C/C++ development
sudo apt-get install -y clang clangd ctags

# For font support
sudo apt-get install -y fontconfig

Installation

Neovim and Vim configuration files will be installed if Neovim or Vim is installed on the system. The configuration files will be installed in the user's home directory.

Option 1: Complete Installation (Vim + Neovim with init.vim)

This installs both Vim and Neovim configurations using the traditional Vundle plugin manager.

Linux

./install.sh

Windows

./install.bat

Option 2: Modern Neovim Setup (init.lua with lazy.nvim)

This installs only the modern Lua-based Neovim configuration with lazy.nvim.

Linux

./setup-nvim.sh

Windows

./setup-nvim.bat

Note: When using init.lua, plugins will be automatically installed on the first launch of Neovim.

Uninstallation

To remove Neovim configuration:

./purge-nvim.sh  # Linux
./purge-nvim.bat # Windows

To remove all Vim and Neovim configurations:

./purge.sh  # Linux
./purge.bat # Windows

Troubleshooting

Plugins not loading

If plugins don't load:

For init.vim: Run :PluginInstall inside Vim/Neovim

For init.lua: Restart Neovim; lazy.nvim will auto-install on first launch

Nerd Fonts not displaying correctly

1. Ensure font cache is updated: fc-cache -fv
2. Set your terminal to use the installed Nerd Font
3. For init.vim, the font is auto-downloaded during installation

LSP not working (init.lua)

1. Ensure clangd is installed: sudo apt-get install clangd
2. For other languages, use :Mason to install language servers

init.lua vs init.vim conflict

Neovim loads init.lua by default if both exist. To switch:

• Remove the unwanted config: rm ~/.config/nvim/init.lua or rm ~/.config/nvim/init.vim
• Or use different installation scripts
