Neovim config (general/development)

Global settings

set nocompatible        
set completeopt=preview 
set tabstop=4
set shiftwidth=4
set expandtab

These standard vim settings will make the tab key insert 4 spaces instead of using a tab character, and use preview mode instead of auto-completing when using completion plugins.

set encoding=utf-8
set nu
set hidden   
set noshowmode

We set the encondig to UTF-8 and show the number line. Setting hidden allows you to quit a buffer without saving it.
We don't need showmode since we will be using vim-airline for status.

set nobackup
set nowritebackup
set noswapfile

Backups, swapfiles and others are disabled. If your system is unstable, you might want to delete those lines, however it can cause problems with servers and cause messy folders.

Custom settings

autocmd Filetype ruby setlocal ts=2 sw=2 
autocmd Filetype slim setlocal ts=2 sw=2
filetype plugin indent on

Using tabspaces of 2 on ruby files. (Maybe should use some plugin to manage this, WIP)

funcion! WinMove(key)
    let t:curwin = winnr()
    exec "wincmd ".a:key
    if (t:curwin == winnr())
        if (match(a:key,'[jk]'))
            wincmd v
        else
            wincmd s
        endif
        exec "wincmd ".a:key
    endif
endfunction

nnoremap <silent> <C-h> :call WinMove('h')<CR>
nnoremap <silent> <C-j> :call WinMove('j')<CR>
nnoremap <silent> <C-k> :call WinMove('k')<CR>
nnoremap <silent> <C-l> :call WinMove('l')<CR>

This function and remap lets us use Ctrl + hjkl keys to move windows in neovim

Key bindings

noremap <C-q> :bd<CR>
map <C-n> :NERDTreeToggle<CR>
map ; :Files<CR> 
map ' :Rg<CR>
nmap <leader>ln :noh<CR>

• CTRL+Q -> Close buffer
• CTRL+N -> Open NERDTree
• \ln -> Disable highlighting
• ' -> Search by matching inside files (using fzf + ripgrep)
• ; -> Search by matching name of files (using fzf + fd)

Plugin settings

call plug#begin('~/.vim/plugged')
Plug 'preservim/nerdtree'

We use vim-plug for plugin management. More information on how to set it up on its GitHub repo

Plugin list:

• NERDTree for browsing directories as trees
• ConquerOfCompletion as a completion engine (compatible with VSCode ones)
• fzf as a fuzzy file finder
• vim-airline as a status line
• vim-gitgutter minimalist git plugin
• vim-sandwich and auto-pairs for brackets management

Vim-airline settings

let g:airline_powerline_fonts = 1
let g:airline#extensions#tabline#enabled = 1
let g:airline_theme='term'
let g:airline#extensions#whitespace#enabled = 0 

Enable powerline fonts

Fzf settings/tips

In order to use fd (fast rust alternative to find) with Fzf, install fd and add this to your .bashrc:

export FZF_DEFAULT_COMMAND='fd --type f --hidden --exclude .git --exclude .vim'

To use ripgrep, simply install it and use :Rg (or the shortcut ')

CoC (ConquerOfCompletion) settings/tips

In order to install a particular langauge completion, use :CocInstall
Here is a small list:

• coc-go Golang completion
• coc-rls Rust completion
• coc-pyright Python completion and static analyzer
• coc-sh Bash completion
