e

use vifm to open neovim via tmux as easy as the likes of NERDTree.

Setup

• put a symlink to e in your bin/ folder (~/.local/bin, ~/bin or whatever)
• edit vifm config, add the following lines somewhere

  "save current tmux pane 
  if $TMUX 
      let $VIFM_TMUX_SESSION_NAME = system("tmux lsw -F '#{session_name}' -f '#{window_active}'")
      let $VIFM_TMUX_WINDOW_INDEX = system("tmux lsw -F '#{window_index}' -f '#{window_active}'")
  endif
  
  " Open file in existing instance of neovim (tmux-aware)
  nnoremap o :execute "!e @".$VIFM_TMUX_SESSION_NAME.":".$VIFM_TMUX_WINDOW_INDEX." %f &"<cr>
  

How to use

From vifm

press o on a file. It'll open in a pane to the right of vifm (maybe you should also do a :split instead of a :vsplit). Select another file and press o again. It'll open in the same instance of neovim. Magic!

From elsewhere

e @<session-name>:<window-number> <file>: will open a <file> in the specified session of tmux inside a specified window.
