Modeline only appears in non-file buffers

[trbjo]

I have a problem, where the mode-line only is visible in buffers not associated with files (e.g. scratch, dired). As soon as i open an existing file, the modeline completely disappears.

I tried removing modules from my .emacs, but to no avail. It doesn't work with the following .emacs:

`
(require 'package)
(setq package-enable-at-startup nil)
(add-to-list 'package-archives '("ORG" . "http://orgmode.org/elpa/") t)
(add-to-list 'package-archives '("MELPA STABLE" . "http://stable.melpa.org/packages/"))
(add-to-list 'package-archives '("MELPA" . "http://melpa.org/packages/"))
(add-to-list 'package-archives '("MARMALADE" . "http://marmalade-repo.org/packages/"))
(add-to-list 'package-archives '("GNU ELPA" . "http://elpa.gnu.org/packages/"))
(setq package-archive-priorities
'(("ORG" . 10)
;;("MELPA STABLE" . 7)
("GNU ELPA" . 5)
;;("MARMALADE" . 2)
("MELPA" . 9)))

(package-initialize)

(unless (package-installed-p 'use-package)
(package-refresh-contents)
(package-install 'use-package))

(eval-when-compile
(require 'use-package))
(setq use-package-always-ensure t)
(require 'bind-key)

;;; Use-package
(use-package projectile)
(use-package shrink-path)
(use-package eldoc-eval)
(load "~/.emacs.d/doom-modeline.el")
(require 'doom-modeline)
(+doom-modeline|init)
`

(also, the package is not available on Melpa yet)

Thanks for the reporting. Actually the package has not been approved by Melpa so far.

Regarding this issue, I tested with your configurations. It seems the all-the-icons package is missing. Please add (use-package all-the-icons) and retry. It works well for me as below.

[trbjo]

It still doesn't work for me. I am on Windows if that makes any difference.

[trbjo]

I found this in the Messages buffer

../../../Users/Troels/.emacs.d/doom-modeline.el: ‘when-let’ is an obsolete macro (as of 26.1); use ‘when-let*’ instead. [3 times] Loading c:/Users/Troels/.emacs.d/doom-modeline.el (source)...done

[seagle0128]

Does it work now?
Yes. I also noticed this warning. But for Emacs 24 and 25, there is no when-let*. Let me look into and address it.

[trbjo]

It still doesn't work, but after changing when-let to when-let* I now get this error:
Error during redisplay: (eval (doom-modeline-format--main)) signaled (invalid-regexp "Trailing backslash") [4 times]

[seagle0128]

OK. Did you install all-the-icons fonts? Run M-x all-the-icons-install-fonts. It should be the fonts issue here.

[trbjo]

Yes, I have run the command, and I'm afraid it doesn't change anything.

[trbjo]

I think this might be an issue with the encoding in Windows. I'll be back.

[seagle0128]

Please try other fonts or encodings. Hmm, I am not using Windows now :(

[seagle0128]

If the fonts are still not displayed correctly, please try to put these codes in init.el (after (require 'doom-modeline)) , and let me know the results.

(defun +doom-maybe-icon-octicon (&rest args)
  (when (and (display-graphic-p) (not (eq system-type 'windows-nt)))
    (apply 'all-the-icons-octicon args)))

(defun +doom-maybe-icon-faicon (&rest args)
  (when (and (display-graphic-p) (not (eq system-type 'windows-nt)))
    (apply 'all-the-icons-faicon args)))

(defun +doom-maybe-icon-material (&rest args)
  (when (and (display-graphic-p) (not (eq system-type 'windows-nt)))
    (apply 'all-the-icons-material args)))

[trbjo]

I have now tested it on my work computer, and it's the same thing. The lisp code above doesn't change anything :-(

[seagle0128]

Also on Windows? Any output in the Messages buffer?

[trbjo]

Yes, my work computer runs Windows. And the output in *Messages* is exactly the same.

[seagle0128]

I tested on Windows just now. It works fine. Please update and retry. I am using consolas fonts with GNU Emacs 26.1 on Windows 10.

[trbjo]

It's working! Turns out I was running 26.093 or something like that. I've now upgraded to 26.1. Thank you so much.

[seagle0128]

Welcome! I disabled all-the-icons in Windows due to the bad performance and formats. Please refer to my latest commit. In my testing, the icons are not showed correctly.

I'm closing this issue. Please let me know if you still have questions. Thanks.

[trbjo]

Have you seen this?

Putting (setq inhibit-compacting-font-caches t) in my .emacs solves the issue for me.

[seagle0128]

Thanks!

I tried this workaround, but seems it doesn't work. The icons in modeline are messy, and the Emacs is extremely slow after I updated all-the-icons. Actually the Emacs consumes 3GB memory if turning on all-the-icons on Windows 10. So I decided to disable it.

All icons are showed correctly on your side? Can I see the screenshot?

On my Windows laptop, the icons are like this

[seagle0128]

@VirgiliusHaufniensis I enabled all-the-icons on Windows now. The root cause is the font issue and it has been fixed in my config (seagle0128/.emacs.d@7e0e69e).

Please update and try on your env. For develop branch, it has been merged new codes, also stable now.

[yiufung]

Hmm I'm still having the same issue using Emacs 26.1 in Windows 10. All fonts from all-the-icons have been installed.

Modeline is only shown on special buffers, *scratch* etc. The error message in *Message* is:

Have also tried putting (setq inhibit-compacting-font-caches t) before doom-modeline, doesn't work either.

[seagle0128]

Hi @yiufung ,

1. Please use the latest Emacs 26.1.
2. Please update doom-modeline to the latest version.
3. Run M-x all-the-icons-install-fonts and install the dwonloaded fonts manually.
4. Try with these configs if using cnfonts.

(defun cnfonts--set-all-the-icons-fonts (&optional _)
    "Show icons in all-the-icons."
    (when (featurep 'all-the-icons)
      (dolist (charset '(kana han cjk-misc bopomofo gb18030))
        (set-fontset-font "fontset-default" charset "all-the-icons" nil 'append)
        (set-fontset-font "fontset-default" charset "github-octicons" nil 'append)
        (set-fontset-font "fontset-default" charset "FontAwesome" nil 'append)
        (set-fontset-font "fontset-default" charset "Material Icons" nil 'append))))

(add-hook 'cnfonts-set-font-finish  #'cnfonts--set-all-the-icons-fonts)

5. Remove the suspicious sections in mode-line below, then re-evaluate (C-x C-e).

(doom-modeline-def-modeline main
                            (workspace-number window-number bar matches " " buffer-info buffer-position  " " selection-info)
                            (global buffer-encoding major-mode vcs flycheck))

if you still encounter this issue, try M-x toggle-debug-on-error, and provide more errors for troubleshooting.
