Make sure you're on the latest versions of neovim and tmux. Then make sure to back up your current dotfiles if you have any, by running the following:

mv ~/.vimrc ~/.vimrc.bak
mv ~/.tmux.conf ~/.tmux.conf.bak
mv ~/.config/nvim/coc-settings.json ~/.config/nvim/coc-settings.json.bak
mv ~/vimwiki ~/vimwikibck

Navigate to the directory root for this repo. Then run:

ln -sf "$(pwd)/.vimrc" ~/.vimrc
ln -sf "$(pwd)/.tmux.conf" ~/.tmux.conf
ln -sf "$(pwd)/coc-settings.json" ~/.config/nvim/coc-settings.json
ln -sf "$(pwd)/vimwiki" ~/vimwiki

This will create symbolic links to each of the files in your home directory. The -s option makes the link symbolic, and the -f option ensures that the symlink will overwrite any currently existing file, which should be fine so long as you backed them up!

To make sure neovim is properly hooked up to your vim config, run the following from inside neovim (taken from running :help nvim-from-vim):

:call mkdir(stdpath('config'), 'p')
:exe 'edit '.stdpath('config').'/init.vim'

Then add these contents to init.vim:

set runtimepath^=~/.vim runtimepath+=~/.vim/after
let &packpath = &runtimepath
source ~/.vimrc

You'll need to download Vim-Plug by following the instructions here.

Open vim with:

vim ~/.vimrc

Then while inside vim, run:

:PlugInstall

This will install all of the plugins. Then run:

:so %

To re-source the .vimrc. You'll also need to install COC language extensions for the languages you intend to use (the list can be found here)

Follow the instructions for installing Tmux Plugin Manager.

Open a new tmux session by running:

tmux attach

Then press prefix + I to install all of the plugins.

You'll probably want to map your caps lock key to escape.

You may need to add this to your .zshrc:

export TERM=xterm-256color

You'll also want to install the silver surfer to speed up ctrl-p:

brew install the_silver_searcher

Install GNU-Grep to take advantage of Perl-compatible regular expressions:

brew install grep

And add this to your .zshrc:

export PATH="/usr/local/opt/grep/libexec/gnubin:$PATH"

Enable vi-mode by adding the plugin to your oh-my-zsh plugins in .zshrc:

plugins=(git vi-mode)

You can add italics to your terminal by following the instructions given here. Most of the steps should already have been incorporated, but you will need to create an xterm-256color-italic.terminfo:

xterm-256color-italic|xterm with 256 colors and italic,
  sitm=\E[3m, ritm=\E[23m,
  use=xterm-256color,

And tmux-256color.terminfo:

tmux-256color|tmux with 256 colors,
  ritm=\E[23m, rmso=\E[27m, sitm=\E[3m, smso=\E[7m, Ms@,
  khome=\E[1~, kend=\E[4~,
  use=xterm-256color, use=screen-256color,

And install them by running:

tic -x xterm-256color-italic.terminfo
tic -x tmux-256color.terminfo

In iTerm, you'll then need to go to Preferences > Profiles > Default, make sure that Text > Italic text allowed is checked, and set Terminal > Report Terminal Type to xterm-256color-italic

You can use vim for resolving git conflicts by running git config --global --edit and adding the following:

[merge]
    tool = vimdiff
[mergetool]
    keepBackup = false
    prompt = false
[mergetool "vimdiff"]
    cmd = nvim -d $BASE $LOCAL $REMOTE $MERGED -c '$wincmd w' -c 'wincmd J'

The markdown-preview plugin requires yarn. Make sure to install it with

brew install yarn
