When we diminish a mode, we are saying we want it to continue doing its work for us, but we no longer want to be reminded of it. It becomes a night worker, like a janitor; it becomes an invisible man; it remains a component, perhaps an important one, sometimes an indispensable one, of the mechanism that maintains the day-people's world, but its place in their thoughts is diminished, usually to nothing. As we grow old we diminish more and more such thoughts, such people, usually to nothing. -- Will Mengarini
This package implements hiding or abbreviation of the mode line displays (lighters) of minor-modes.
(require 'diminish) (diminish 'rainbow-mode) ; Hide lighter from mode-line (diminish 'rainbow-mode " Rbow") ; Replace rainbow-mode lighter with " Rbow" (diminish 'rainbow-mode 'rainbow-mode-lighter) ; Use raingow-mode-lighter variable value (diminish 'rainbow-mode '(" " "R-" "bow")) ; Replace rainbow-mode lighter with " R-bow" (diminish 'rainbow-mode '((" " "R") "/" "bow")) ; Replace rainbow-mode lighter with " R/bow" (diminish 'rainbow-mode '(:eval (format " Rbow/%s" (+ 2 3)))) ; Replace rainbow-mode lighter with " Rbow/5" (diminish 'rainbow-mode ; Replace rainbow-mode lighter with greened " Rbow" '(:propertize " Rbow" face '(:foreground "green"))) (diminish 'rainbow-mode ; If rainbow-mode-mode-linep is non-nil " Rbow/t" '(rainbow-mode-mode-linep " Rbow/t" " Rbow/nil")) (diminish 'rainbow-mode '(3 " Rbow" "/" "s")) ; Replace rainbow-mode lighter with " Rb"
John Wiegley's use-package macro also has support for diminish.el.
