;;; Commentary:
|
||
;;
|
||
;; This package offers a fancy and fast mode-line inspired by minimalism design.
|
||
;;
|
||
;; It's integrated into Doom Emacs (https://github.com/hlissner/doom-emacs) and
|
||
;; Centaur Emacs (https://github.com/seagle0128/.emacs.d).
|
||
;;
|
||
;; The doom-modeline offers:
|
||
;; - A match count panel (for anzu, iedit, multiple-cursors, symbol-overlay,
|
||
;; evil-search and evil-substitute)
|
||
;; - An indicator for recording a macro
|
||
;; - Current environment version (e.g. python, ruby, go, etc.) in the major-mode
|
||
;; - A customizable mode-line height (see doom-modeline-height)
|
||
;; - A minor modes segment which is compatible with minions
|
||
;; - An error/warning count segment for flymake/flycheck
|
||
;; - A workspace number segment for eyebrowse
|
||
;; - A perspective name segment for persp-mode
|
||
;; - A window number segment for winum and window-numbering
|
||
;; - An indicator for modal editing state, including evil, overwrite, god, ryo
|
||
;; and xah-fly-keys, etc.
|
||
;; - An indicator for battery status
|
||
;; - An indicator for current input method
|
||
;; - An indicator for debug state
|
||
;; - An indicator for remote host
|
||
;; - An indicator for LSP state with lsp-mode or eglot
|
||
;; - An indicator for github notifications
|
||
;; - An indicator for unread emails with mu4e-alert
|
||
;; - An indicator for unread emails with gnus (basically builtin)
|
||
;; - An indicator for irc notifications with circe, rcirc or erc.
|
||
;; - An indicator for buffer position which is compatible with nyan-mode or poke-line
|
||
;; - An indicator for party parrot
|
||
;; - An indicator for PDF page number with pdf-tools
|
||
;; - An indicator for markdown/org previews with grip
|
||
;; - Truncated file name, file icon, buffer state and project name in buffer
|
||
;; information segment, which is compatible with project, find-file-in-project
|
||
;; and projectile
|
||
;; - New mode-line for Info-mode buffers
|
||
;; - New package mode-line for paradox
|
||
;; - New mode-line for helm buffers
|
||
;; - New mode-line for git-timemachine buffers
