perfect-vimrc

My vim/nvim config entirely in vimscript with Conqueror of Completion, to setup environment for different programming languages

Prerequisites:

Make sure you already have a backup of your previous vim-config (if any). In case you have already a vim-config and you don’t want to lose it, you can make a backup file using the command below before creating the new .vimrc -
```
    mv .vimrc .vimrc.bak
```
Also Make sure you run the command in the directory where your already existing .vimrc is located. The command will rename it with a .bak file-extension which stands for backup. Now this backup file can be stored/located wherever wanted.
install vim-plug, nodejs, yarn, & build-essentials.

Note:

This config can also be used for NeoVim if wanted. Just replace the directory ~/.vim/plugged with .local/share/nvim/plugged in the first line of the section of the config shown below, before performing the 2nd step of Instructions -

call plug#begin('~/.vim/plugged')
" Plug 'vim-airline/vim-airline'
Plug 'vim-airline/vim-airline'
" Plug coc.nvim for C/C++ lsp
Plug 'neoclide/coc.nvim'
Plug 'jiangmiao/auto-pairs'
Plug 'vim-airline/vim-airline-themes'
Plug 'gruvbox-community/gruvbox'
Plug 'catppuccin/vim', { 'as': 'catppuccin' }
Plug 'sonph/onehalf', { 'rtp': 'vim' }
Plug 'preservim/nerdtree'
Plug 'christoomey/vim-tmux-navigator'
Plug 'ryanoasis/vim-devicons'
" Plug 'Exafunction/codeium.vim', { 'branch': 'main' }
Plug 'prasada7/toggleterm.vim'
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim'
call plug#end()

Actual Work

Copy the whole text of the config.vim file in this repo and paste it in your own blank .vimrc file. Save it.
Next Run the command :PlugInstall inside vim (According to the config, I’m using Vim-Plug plugin manager. If you use any other plugin manager like vundle or packer, you are free to change the config file wherever needed and then run the plugin manager’s install command). You may need to run the command after restarting vim. You may also need to run :PLugClean to remove all the previously installed plugins.
After all plugins are installed run the :PlugUpdate command inside vim to update the already installed plugins.
Before to be able to use coc.nvim you will need to run npm ci in the directory ~/.vim/plugged/coc.nvim (if you are using vim) or ~/.local/share/nvim/plugged/coc.nvim (if you are using neovim) to activate it.
Now run :CocInstall coc-clangd inside vim to install the required lsp for C and C++, :CocInstall coc-pyright to install the required lsp for python. :CocInstall coc-tsserver coc-json coc-eslint is recommended javascript/typescript + json lsp support. You can find the required lsp for the programming language that you use on this page of coc.nvim repo.
Now navigate to your project directory, and check if the setup is working properly.
(Optional): Uncomment the line Plug 'Exafunction/codeium.vim', { 'branch': 'main' } in the config file and run :PlugInstall to install the Codeium AI plugin in vim. After installation refer to the Official Codeium AI installation and usage guide .
Enjoy!
