I do all of my work in the latest possible version of Vim. I usually run Vim inside tmux, itself run in alacritty. My Alacritty config is in my dotfiles repo.
To install the repo:
git clone <this repo> ~/repos/
pushd ~ && ln -s ~/reps/vimrc .vim && ln -s ~/.vim/vimrc ~/.vimrc && popd
Then, open vim and run PlugInstall.
To use fzf to open files with ctrl-p (for files in git) and ctrl-o (files in the filesystem), you'll need to have fzf installed.
I think my vimrc is ready to use as-is for most people, but there are a few gotchas that have annoyed my pair-programming parners:
1: I use the movement-variant of ~, so if you want to change case on a single character you'll need to cursor over it and do something like ~l
2: I have a pretty long status line; when it doesn't fit into the width of your terminal, it causes vim to throw random "Press ENTER" messages.
