nvim-terminus

Edit your current command in a scratch buffer. The command may come from any shell running inside a Neovim terminal, e.g. bash/fish/lua/ruby/...

This plugin provides the same functionality as nvim-editcommand but uses jobcontrol to communicate with the terminal rather than the dirty vimscipt hack used by nvim-editcommand. The downside of this is that terminals must be started using the TerminusOpen function/command provided by this plugin. The upside is we now have access to the stdin/stdout of the terminal.

This plugin differs from neoterm in that nvim-terminus allows you to edit a command from a terminal, inside a text buffer, while neoterm allows you to run a command from a text buffer inside a terminal.

Features

Run Neovim commands from the terminal

While in TERMINAL mode any command beginning with : will be intercepted and executed as a command in Neovim. For example; opening files in the current Neovim instance (:e ~/.config/nvim/init.vim).

nvim-terminus will set Neovim's working directory to the shell's current working directory before the command is executed.

Edit terminal commands in Neovim

While in TERMINAL mode <c-x> can be used to open the current command inside a scratch buffer. The contents of the scratch buffer are then sent back to the terminal (via stdin) once the scratch buffer is closed.

Use Xterm title

Use the xterm title as the terminal buffer name. This makes it much easier to differentiate between different terminal buffers. The title will depend on what your shell emits, fish shell will show the current command and directory.

:ls with Xterm titles enabled

:ls
  1   h- "1 fish  /tmp"                    line 45
  5  %a- "5 brettanomyces@brettanomyces: ~/Workspace"                    line 45
  12  h- "12 sl  /home/brettanomyces"                           line 45

:ls without Xterm titles enabled

:ls
  3   h- "termp:/.//7596:/usr/local/bin/fish" line 45
  4  #h- "termp:/.//7627:/usr/local/bin/fish" line 45
  5  %a- "termp:/.//7686:/usr/local/bin/fish" line 45

If you are using fish-shell then you can control what is displayed in the title by defining ~/.config/fish/functions/fish_title.fish

function fish_title
  echo -n 'a really good title'
end
