WezTerm Integration

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
    -- return 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') },
    },
}
