Ask your question!

I want to set the tab title to the active pane's current_working_dir, as per mentioned in #915 (comment)

So I have this which is not workin:

wezterm.on("format-tab-title", function(tab, tabs, panes, config, hover, max_width)
  local pane = tab.active_pane
  local cwd = pane.current_working_dir
  return {
    -- { Text = " " .. " hello " .. " " }, -- this works
    { Text = " " .. cwd .. " " }, -- this doesn't work
  }
end)

Any suggestion on how to make this work?

Thanks in advance!

Same question. Nothing, I tried, seems to work on MacOS.

pane.current_working_dir is Url object

to fix try { Text = " " .. cwd.path .. " " }

Thank you for the quick reply, Estin. ChatGPT just came to the same conclusions.
Also pane.current_working_dir.path will have escaped spaces (%20) and possibly other characters; here's the decoder function:

local function decodeURI(path)
  if not path then
    return ''
  end
  -- Replace %20, %3A, etc., with the actual character
  path = path:gsub("%%(%x%x)", function(hex)
    return string.char(tonumber(hex, 16))
  end)
  return path
end

@habahabahaba
Url object also has attribute file_path - decodes the path field and interprets it as a file path

That simplifies things, thank you again.

Actually, I have resolved this for me using the shell integration instead, that is, setting the window title via the shell. In my case, using fish, I accomplished what I wanted (and more, e.g., adding the git branch as well), with the following:

function fish_title
    # Get shortened path without the full home path
    # basename (prompt_pwd)

    # Get current working directory
    set -l wd (prompt_pwd)

    # Try to get git branch
    set -l git_branch (command git rev-parse --abbrev-ref HEAD 2>/dev/null)

    if test -n "$git_branch"
        echo "$wd ($git_branch)"
    else
        echo $wd
    end
end
