Install FZF, Ripgrep, Universal-ctags, Silver-searcher

First let's just install a bunch of awesome tools to help you search/find stuff

Mac

brew install fzf

# To install useful key bindings and fuzzy completion:

$(brew --prefix)/opt/fzf/install
brew install ripgrep
brew install --HEAD universal-ctags/universal-ctags/universal-ctags
brew install the_silver_searcher
brew install fd

Ubuntu (I think there's snaps for this stuff too)

sudo apt install fzf
sudo apt install ripgrep
sudo apt install universal-ctags
sudo apt install silversearcher-ag
sudo apt install fd-find

Arch

sudo pacman -S fzf
sudo pacman -S ripgrep
yay -S universal-ctags-git
sudo pacman -S the_silver_searcher
pacman -S fd

Plug FZF & vim-rooter into vim

Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim'
Plug 'airblade/vim-rooter'

Configuration

Note on extra keybindings

Read more about keybindings here It is sufficient to source these files below in your bashrc or zshrc for completion and keybindings

/usr/share/fzf/completion.zsh
/usr/share/fzf/key-bindings.zsh

/usr/share/fzf/completion.bash
/usr/share/fzf/key-bindings.bash

Another note

From the Archwiki, commands to query packages and install them

sudo pacman -Fy # <- only run this once
pacman -Slq | fzf -m --preview 'cat <(pacman -Si {1}) <(pacman -Fl {1} | awk "{print \$2}")' | xargs -ro sudo pacman -S
yay -Slq | fzf -m --preview 'cat <(yay -Si {1}) <(yay -Fl {1} | awk "{print \$2}")' | xargs -ro  yay -S
