Install

Manual

From melpa, M-x package-install RET doom-modeline RET.

In init.el,

(require 'doom-modeline)
(doom-modeline-mode 1)

(add-hook 'after-init-hook #'doom-modeline-mode)

Use-package

(use-package doom-modeline
  :ensure t
  :init (doom-modeline-mode 1))

(use-package doom-modeline
  :ensure t
  :hook (after-init . doom-modeline-mode))

This package is able to display icons if all-the-icons package and required fonts are installed. Run M-x all-the-icons-install-fonts to install the necessary fonts. Please refer to the installation guide.

Add this to init.el if you want to use icons,

;; Install via `M-x package-install RET all-the-icons RET`
(require 'all-the-icons)

FAQ

How to display icons correctly?

all-the-icons are necessary. Then run M-x all-the-icons-install-fonts to install the resource fonts. On Windows, the fonts should be installed manually. all-the-icons only support GUI. If you don't like color icons, (setq all-the-icons-color-icons nil) to disable it. Please refer to all-the-icons.el for details.

If the icons are not displayed correctly although all-the-icons fonts are installed correctly, please install the non-free font Symbola. This issue usually occurs on Windows.

If you are using cnfonts, it will conflict with all-the-icons. The workaround is here.

In terminal mode, no icons or bars will be displayed, even though all-the-icons fonts are installed successfully, and doom-modeline-icon is non-nil.
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)
```
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.
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

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))

;; Add to `doom-modeline-mode-hook` or other hooks
(defun setup-custom-doom-modeline ()
   (doom-modeline-set-modeline 'my-simple-line 'default))
(add-hook 'doom-modeline-mode-hook 'setup-custom-doom-modeline)

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)

(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.

The right side of the modeline is cut off. How to fix it?
- Tweak all-the-icons-scale-factor. e.g. (setq all-the-icons-scale-factor 1.1)
- Use another font family or size. See above.

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.

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

Yes. For better experience, should enable anzu-mode and load evil-anzu.
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)))))
```
How to display company mode-line information?

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