Emacs Tab-bar-mode
To enable tab bars:
(tab-bar-mode 1)
(desktop-save-mode 1)
desktop-save-mode enables tabs between sessions
toggle-frame-tab-bar enable the display of the Tab Bar on some frames and disable it on others
=C-x t = the prefix key for creating tabs of various kinds
C-x t 2 adds a new tab next to the currently active tab. By default the new tab is a clone of the currently active tab.
You can control the choice of the buffer displayed in a new tab by customizing the variable tab-bar-new-tab-choice.
With tab-bar-new-tab-choice what is the difference between:
current buffer - opens the current buffer in the new tab
current window - duplicate the content of the current window
buffer - opens a specific buffer like scratch
directory - opens a dedicated dired buffer of one's choice
file - opens a dedicated file of one's choice
function - runs a function of one's choice, i.e. customize the behavior of new tabs in Emacs beyond the default options
To control the names of new tabs: tab-bar-tab-name-function
To switch to an existing buffer in a tab: switch-to-buffer-other-tab C-x t b
To find a specific file in a tab: find-file-other-tab C-x tf
To find a specific directory: dired-other-tab C-x t d
Very important command
C-x t t is an important PREFIX command that you run BEFORE running any another command. A new buffer of your choice is then created in a new tab.
tab-bar-new-tab-to defines WHERE to position the newly created tab
C-x t 0 close selected tab (buffer stays open)
C-x t 1 close all tabs except currently selected tab
C-TAB switches between tabs
S-C-TAB previous tab
C-x t r rename current tab
To change the colrs of the current tab:
At present I cannot easily see which tab is the current tab because the colors are all light greys. To change the colors of current tab:
;; Change colors of current tab (set-face-attribute 'tab-bar-tab nil :background "dark orange" :foreground "black") (set-face-attribute 'tab-bar-tab-inactive nil :background "gray" :foreground "black")
