A fancy and fast mode-line inspired by minimalism design.

It's integrated into Centaur Emacs, Doom Emacs and Spacemacs.

Feature

The doom-modeline was designed for minimalism, and offers:

• A match count panel (for anzu, iedit, multiple-cursors, symbol-overlay, and evil-search, etc.)
• 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/name segment for eyebrowse or tab-bar-mode
• A perspective name segment for persp-mode
• A window number segment for ace-window, 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 markdown/org preview with grip
• Truncated file name, file icon, buffer state and project name in buffer information segment, which is compatible with project, projectile and find-file-in-project.

FAQ

1. How to display icons correctly?

   nerd-icons are necessary. Then run M-x nerd-icons-install-fonts to install the resource fonts. On Windows, the fonts should be installed manually. nerd-icons supports both GUI and TUI.

   If you don't like color icons, (setq nerd-icons-color-icons nil) to disable it. Please refer to nerd-icons.el for details.

   If you prefer all-the-icons, please use release 3.4.0. It hasn't been supported since 4.0.0.

2. I am experiencing the laggy issue, how to resolve it?

   Add this configuration into your init file:

   ;; Don’t compact font caches during GC.
   (setq inhibit-compacting-font-caches t)

3. A ridiculous path is displayed on the mode-line while visiting a symbolink.

   It's the default behaviors of Vanilla Emacs. If you want to display the real names, please put this into your init file.

   (setq find-file-visit-truename t)

   If the file is controlled by vc, refer to the documentation of vc-follow-symlinks.

4. Why doesn't change of branch reflect in modeline?

   Actually it's related to magit and vc-mode.

   • Workaround:
     • Revert the buffers manually.
     • (setq auto-revert-check-vc-info t) brings the performance issue.
   • Refer to:
     • The mode-line information isn’t always up-to-date
     • Maybe provide an alternative to VC's mode-line information

5. Can I add my mode-line segments myself? How to do that? How can I define my own mode-line?

   There are two methods.

   • If the information is simple, just add to mode-line-misc-info or global-mode-string.

   • Use doom-modeline-def-modeline to define your own mode-line and set it as default.

     For example:

     ;; Define your custom doom-modeline
     (doom-modeline-def-modeline 'my-simple-line
       '(bar matches buffer-info remote-host buffer-position parrot selection-info)
       '(misc-info minor-modes input-method buffer-encoding major-mode process vcs checker))
     
     ;; Set default mode-line
     (add-hook 'doom-modeline-mode-hook
               (lambda ()
                 (doom-modeline-set-modeline 'my-simple-line 'default)))
     
     ;; Configure other mode-lines based on major modes
     (add-to-list 'doom-modeline-mode-alist '(my-mode . my-simple-line))
     
     ;; Or disable other mode-lines
     (setq 'doom-modeline-mode-alist nil)

6. How to specify font family and size in modeline?

   For example:

   (setq doom-modeline-height 1) ; optional
   (if (facep 'mode-line-active)
       (set-face-attribute 'mode-line-active nil :family "Noto Sans" :height 100) ; For 29+
     (set-face-attribute 'mode-line nil :family "Noto Sans" :height 100))
   (set-face-attribute 'mode-line-inactive nil :family "Noto Sans" :height 100)

   or

   (setq doom-modeline-height 1) ; optional
   (custom-set-faces
     '(mode-line ((t (:family "Noto Sans" :height 0.9))))
     '(mode-line-active ((t (:family "Noto Sans" :height 0.9)))) ; For 29+
     '(mode-line-inactive ((t (:family "Noto Sans" :height 0.9)))))

   Please refer to #189 and #301.

7. The right side of the modeline is cut off. How to fix it?

   • Tweak nerd-icons-scale-factor. e.g. (setq nerd-icons-scale-factor 1.1)
   • Use another font family or size. See above.

8. How to disable symbolic links expanding in mode-line?

   If you encounter the issue like this

   

   please try this:

   ;; built-in `project' on 26+
   (setq doom-modeline-project-detection 'project)
   ;; or `find-in-project' if it's installed
   (setq doom-modeline-project-detection 'ffip)

   For more details, refer to #209 and #224.

9. Can doom-modeline show match count while search with evil-search?

   Yes. For better experience, should enable anzu-mode and load evil-anzu.

10. How to show that the R is running in inferior ess R mode?

    The ess R mode modifies mode-line-buffer-identification directly to display the status. To display the status in doom-modeline, you can add the status to mode-line-process or global-mode-string as below.

    (add-hook 'inferior-ess-mode-hook
          (lambda ()
            (add-to-list 'mode-line-process '(:eval (nth ess--busy-count ess-busy-strings)))))

11. How to display company mode-line information?

    Enable doom-modeline-minor-modes or (add-to-list 'global-mode-string company-lighter).

12. How to display LaTeX compilation information in the mode line?

    Use process package. Refer to #387 for more details.

    (require 'procress)
    (procress-load-default-svg-images)
    (add-hook 'LaTeX-mode-hook #'procress-auctex-mode)
