wezterm.nvim

Replacement of

• vim-tmux-navigator
• better-vim-tmux-resizer

for wezterm.

prerequisite

.bashrc / .zshrc

[ -n "$WEZTERM_PANE" ] && export NVIM_LISTEN_ADDRESS="/tmp/nvim$WEZTERM_PANE"

.config/fish/config.fish

if not set -q $WEZTERM_PANE
  set -x NVIM_LISTEN_ADDRESS "/tmp/nvim$WEZTERM_PANE"
end

I just use the original tmux plugins for vim configs.

• vim-tmux-navigator
• better-vim-tmux-resizer

navigator

Currently wezterm doesn't provide api to execute wezterm action inside neovim. So we execute commandline program in wezterm which uses neovim remote msgpack api.

Checkout wez/wezterm#995 for details/updates.

install

cd wezterm.nvim.navigator && go install

wezterm config

local wezterm = require("wezterm")
local os = require("os")

local move_around = function(window, pane, direction_wez, direction_nvim)
  local result = os.execute("env NVIM_LISTEN_ADDRESS=/tmp/nvim" .. pane:pane_id() ..  " wezterm.nvim.navigator " .. direction_nvim)
  if result then
		window:perform_action(wezterm.action({ SendString = "\x17" .. direction_nvim }), pane)
  else
		window:perform_action(wezterm.action({ ActivatePaneDirection = direction_wez }), pane)
  end
end

wezterm.on("move-left", function(window, pane)
	move_around(window, pane, "Left", "h")
end)

wezterm.on("move-right", function(window, pane)
	move_around(window, pane, "Right", "l")
end)

wezterm.on("move-up", function(window, pane)
	move_around(window, pane, "Up", "k")
end)

wezterm.on("move-down", function(window, pane)
	move_around(window, pane, "Down", "j")
end)

wezterm mapping

-- pane move(vim aware)
{ key = "h", mods = "CTRL", action = wezterm.action({ EmitEvent = "move-left" }) },
{ key = "l", mods = "CTRL", action = wezterm.action({ EmitEvent = "move-right" }) },
{ key = "k", mods = "CTRL", action = wezterm.action({ EmitEvent = "move-up" }) },
{ key = "j", mods = "CTRL", action = wezterm.action({ EmitEvent = "move-down" }) },

resizer

local vim_resize = function(window, pane, direction_wez, direction_nvim)
	local result = os.execute(
		"env NVIM_LISTEN_ADDRESS=/tmp/nvim"
			.. pane:pane_id()
			.. " "
			.. homedir
			.. "/bin/"
			.. "wezterm.nvim.navigator "
			.. direction_nvim
	)
	if result then
		window:perform_action(wezterm.action({ SendString = "\x1b" .. direction_nvim }), pane)
	else
		window:perform_action(wezterm.action({ ActivatePaneDirection = direction_wez }), pane)
	end
end

wezterm.on("resize-left", function(window, pane)
	vim_resize(window, pane, "Left", "h")
end)

wezterm.on("resize-right", function(window, pane)
	vim_resize(window, pane, "Right", "l")
end)

wezterm.on("resize-up", function(window, pane)
	vim_resize(window, pane, "Up", "k")
end)

wezterm.on("resize-down", function(window, pane)
	vim_resize(window, pane, "Down", "j")
end)

{ key = "h", mods = "ALT", action = wezterm.action({ EmitEvent = "resize-left" }) },
{ key = "l", mods = "ALT", action = wezterm.action({ EmitEvent = "resize-right" }) },
{ key = "k", mods = "ALT", action = wezterm.action({ EmitEvent = "resize-up" }) },
