Ask your question!

When I have several wezterm windows open, they all have the same title: "wezterm". Which makes it difficult to switch to the right window quickly, as their tiles may look very similar:

Is there a possibility to set the title of wezterm window manually?

Note: I run wezterm with the following settings and usually have one tab only:

config.hide_tab_bar_if_only_one_tab = true
config.window_decorations = "INTEGRATED_BUTTONS|RESIZE"

Now, I am not going to claim that I am using these features as @wez intended/appropriately but instead of having multiple instances of wezterm open like in your above screenshot I have been using combination of SwitchWorkspaceRelative, ShowLauncherArgs { flags = "FUZZY|WORKSPACES" }, rename_workspace, and the command palette to create multiple workspaces all in one wezterm "window".

I have been using that to quickly jump between differently named work areas for myself and it feels clean and organized but I still don't know if its more proper than the multiple open window approach that you are showing above. For all I know they might be equal underneith the hood.

You could likely get creative here

wezterm.on('format-window-title', function()
  local title = 'wezterm'
  -- some logic here
  return title
end)

That is exactly what I needed. Here is my title string:

-- making window titles more distinct
wezterm.on('format-window-title', function()
  local title = '[' .. wezterm.mux.get_active_workspace() .. ']'
  title = title .. ' ' .. wezterm.mux.get_domain():name()
  title = title .. ' - $W'
  -- some logic here
  return title
end)

I want to achieve when I enter a project path, the current window shows me the root directory name of the project I am currently active tab, how to operate?

The following code does not work either, and there is really no problem to find.

wezterm.on('format-window-title', function(window, tab)
      local pane = tab.active_pane
      if not pane then
         return nil
      end

      local current_dir = pane.current_working_dir
      if not current_dir then
         return nil
      end

      local path_parts = wezterm.split_string(current_dir, '/')

      local root_path_name = path_parts[1]

      local title = '[' .. wezterm.mux.get_active_workspace() .. ']'
      title = title .. ' ' .. root_path_name
      title = title .. ' - ' .. pane.title

      return title
   end)
