Expected behavior ================= If tab-bar-show = 1, Tab Bar is not visible when less than two tabs are available. If tab-bar-show = nil, Tab Bar is never visible If tab-bar-show = t, Tab Bar is always visible In addition, I would like to be able to change the value of tab-bar-show to toggle the visibility of the Tab Bar (I don't want to disable the mode, only hide the Tab Bar). Actual behavior and recipe ========================== Run "emacs -q", switch to *scratch* and evaluate the following, in order: (tab-bar-mode) ;; tab bar is shown on top of buffer (setq tab-bar-show 1) ;; no change. Maybe we need to toggle the mode to effect changes? (tab-bar-mode 0) ;; bar disappears (tab-bar-mode) ;; bar still reappears with only one tab ;; expected behavior: tab bar remains hidden because only one tab exists (tab-bar-new-tab) ;; two tabs exist and are visible (tab-bar-close-tab) ;; only one tab is left, tab bar is hidden (tab-bar-mode) ;; turn mode off again (setq tab-bar-show nil) ;; no bar should be visible if I turn tab-bar-mode on again (tab-bar-mode) ;; tab bar is still visible even with the variable set to nil Best regards, Marcel In GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.22, cairo version 1.17.3) of 2020-08-29 built on juergen Windowing system distributor 'The X.Org Foundation', version 11.0.12010000 System Description: Arch Linux Recent messages: For information about GNU Emacs and the GNU system, type C-h C-a.
