Header bar not shown

[LukasCBossert]

With my current setup I do not get the header bar as in your screenshot

I have a blank line instead:

Does my init.el-file taking effect on it?

Hi @LukasCBossert !

Did you install doom-nano-modeline?

If so, this happens if there is an error when generating the decorated string of the modeling. Can you please run (doom-nano-modeline-default-mode) and check if there is any error?

[LukasCBossert]

Hi @ronisbr ,

(doom-nano-modeline-default-mode) is enabled and in my message-buffer I see this

Error during redisplay: (eval (funcall (or (catch 'found (dolist (elt doom-nano-modeline-mode-formats) (let* ((config (cdr elt)) (mode-p (plist-get config :mode-p)) (format (plist-get config :format))) (when mode-p (when (funcall mode-p) (throw 'found format)))))) #'doom-nano-modeline-default-mode-format))) signaled (wrong-number-of-arguments #<subr mapconcat> 2) [8 times]

does this help?

For the sake of completeness:

In my config.el I have:

(after! doom-themes
  (load-theme 'doom-nano-dark t)
  )

(use-package! doom-nano-modeline
  :config
  (doom-nano-modeline-mode 1)
  (global-hide-mode-line-mode 1)
  )

in the packages.el:

(package! doom-nano-modeline
  :recipe (:host github
  :repo "ronisbr/doom-nano-modeline"))

and the two theme-files are in my .doom.d/themes/-folder.

[ronisbr]

Everything is right in your configuration. I have no idea why we are having this problem in mapconcat function. What is you Emacs version?

[LukasCBossert]

GNU Emacs 28.2 (build 1, aarch64-apple-darwin21.6.0, Carbon Version 165 AppKit 2113.6) of 2022-09-15

[ronisbr]

Is it blank in every file? For example, try opening a C++ file.

[LukasCBossert]

yes, each file is affected. Regardless of the type.

[LukasCBossert]

Did you have any time to look into this or any idea what I could do, @ronisbr ?

[ronisbr]

Is it possible to try in a fresh doom section? For example, delete .doom.d, .emacs.d, add doom-nano-themes and doom-nano-modeline, and try again?

[LukasCBossert]

I did a complete new installation and only added the doom-nano-themes and and the doom-nano-modeline (as written above).

Still same error:

Error during redisplay: (eval (funcall (or (catch 'found (dolist (elt doom-nano-modeline-mode-formats) (let* ((config (cdr elt)) (mode-p (plist-get config :mode-p)) (format (plist-get config :format))) (when mode-p (when (funcall mode-p) (throw 'found format)))))) #'doom-nano-modeline-default-mode-format))) signaled (wrong-number-of-arguments #<subr mapconcat> 2) [99 times]

My doom-info is:

I am using Emacs 29. I will install 28 to check if there is some compatibility issue.

[LukasCBossert]

I dont mind upgrading if this helps.... (if you tell me how to do best using homebrew).

[LukasCBossert]

Ok, I installed emacs 29 now and it works!!!!!

[ronisbr]

Wow! Thanks! Probably the function mapreduce changed the API! I need to verify how can I support Emacs 28.

[ronisbr]

I found the problem! The last argument in mapconcat in Emacs 28 is not optional! It should now be fixed by https://github.com/ronisbr/doom-nano-modeline/commit/14a6adb28e06c383c351c1823237abaddfbab4d1

Can you please test in Emacs 28?

[LukasCBossert]

oh - I deleted my Emacs 28 completely......

[ronisbr]

No problem! I will test later :) Thanks!
