Restoring vim and neovim sessions

• save vim/neovim sessions. I recommend tpope/vim-obsession (as almost every plugin, it works for both vim and neovim).

• in .tmux.conf:

    # for vim
    set -g @resurrect-strategy-vim 'session'
    # for neovim
    set -g @resurrect-strategy-nvim 'session'
  

tmux-resurrect will now restore vim and neovim sessions if Session.vim file is present.

If you're using the vim binary provided by MacVim.app then you'll need to set @resurrect-processes, for example:

set -g @resurrect-processes '~Vim -> vim'
