WezTerm Integration

There are 2 examples of wezterm integrations below,
- "get_foreground_process_name" (Does not work if vim is started from somewhere else than the commandline)
- "get_tty_name" (More robust version that understands vim is the fg process if started via
tig
,git commit
,git jump
,chezmoi edit
etc. - Only tested on Ubuntu)
Add the following snippet to your configuration file
. You can change the following keybindings as you may prefer.
local wezterm = require('wezterm')
local act = wezterm.action
local function isViProcess(pane)
-- get_foreground_process_name On Linux, macOS and Windows,
-- the process can be queried to determine this path. Other operating systems
-- (notably, FreeBSD and other unix systems) are not currently supported
return pane:get_foreground_process_name():find('n?vim') ~= nil or pane:get_title():find("n?vim") ~= nil
end
local function conditionalActivatePane(window, pane, pane_direction, vim_direction)
if isViProcess(pane) then
window:perform_action(
-- This should match the keybinds you set in Neovim.
act.SendKey({ key = vim_direction, mods = 'ALT' }),
pane
)
else
window:perform_action(act.ActivatePaneDirection(pane_direction), pane)
end
end
wezterm.on('ActivatePaneDirection-right', function(window, pane)
conditionalActivatePane(window, pane, 'Right', 'l')
end)
wezterm.on('ActivatePaneDirection-left', function(window, pane)
conditionalActivatePane(window, pane, 'Left', 'h')
end)
wezterm.on('ActivatePaneDirection-up', function(window, pane)
conditionalActivatePane(window, pane, 'Up', 'k')
end)
wezterm.on('ActivatePaneDirection-down', function(window, pane)
conditionalActivatePane(window, pane, 'Down', 'j')
end)
return {
-- ...your settings ...
keys = {
{ key = 'h', mods = 'ALT', action = act.EmitEvent('ActivatePaneDirection-left') },
{ key = 'j', mods = 'ALT', action = act.EmitEvent('ActivatePaneDirection-down') },
{ key = 'k', mods = 'ALT', action = act.EmitEvent('ActivatePaneDirection-up') },
{ key = 'l', mods = 'ALT', action = act.EmitEvent('ActivatePaneDirection-right') },
},
}
This approach is more similar to the tmux solution and supports understanding that vim/nvim is the fg process even if it's started through another command (that uses $EDITOR
for example), such as git commit
, git jump
, git rebase
, chezmoi edit
, ...
This uses the tty information provided by wezterm since 20230408 (see pane:get_tty_name).
local w = require 'wezterm'
local a = w.action
local function is_inside_vim(pane)
local tty = pane:get_tty_name()
if tty == nil then return false end
local success, stdout, stderr = w.run_child_process
{ 'sh', '-c',
'ps -o state= -o comm= -t' .. w.shell_quote_arg(tty) .. ' | ' ..
'grep -iqE \'^[^TXZ ]+ +(\\S+\\/)?g?(view|l?n?vim?x?)(diff)?$\'' }
return success
end
local function is_outside_vim(pane) return not is_inside_vim(pane) end
local function bind_if(cond, key, mods, action)
local function callback (win, pane)
if cond(pane) then
win:perform_action(action, pane)
else
win:perform_action(a.SendKey({key=key, mods=mods}), pane)
end
end
return {key=key, mods=mods, action=w.action_callback(callback)}
end
return {
keys = {
bind_if(is_outside_vim, 'h', 'ALT', a.ActivatePaneDirection('Left')),
bind_if(is_outside_vim, 'l', 'ALT', a.ActivatePaneDirection('Right')),
},
}
