Problem with getting all-the-icons-applied

[gabriel4649]

If I run (setq neo-theme (if window-system 'icons 'arrow)) using eval-region I can see the all-the-icons theme being applied. But if I run it from my init file it never gets applied.

The problem was that since I am using emacsclient, it defaults to arrow when emacs --daemon is run. Any alternative to (setq neo-theme (if window-system 'icons 'arrow)) for emacs --daemon users?

The variable window-system's value is nil when run emacs as daemon mode. And the icons theme only supported in GUI emacs.

I got the same problem which all-the-icons doesn't show up in the neotree when running emacs in client/server mode.

The workaround is setting the neo-theme in after-make-frame-functions hook instead of the use-package config.

;; all-the-icons
;; https://github.com/domtronn/all-the-icons.el
(use-package all-the-icons
  :ensure t)

Hope this help. =)
