Treemacs + Doom Modeline on emacs 29.1

[gmemstr]

After updating past commit aa0944a, I encountered the same error describe here: #1046. Interestingly, despite a patch being pushed and confirming I am using the latest commit, I still encounter the error. Rolling back to before the doom modeline patches resolves the issue.

I am using https://github.com/hlissner/emacs-hide-mode-line, which is maybe the only "special" bit of my setup in regards to the modeline, with the relevant init.el config:

(use-package hide-mode-line :straight t)

(add-hook 'treemacs-mode-hook #'hide-mode-line-mode)
(use-package treemacs
  :straight t
  :init (with-eval-after-load 'winum
		  (define-key winum-keymap (kbd "M-0") #'treemacs-select-window))
  :bind
  (:map global-map
		("M-0" . treemacs-select-window)
		("C-x t t" . treemacs)
		("C-x t C-t" . treemacs-find-file)))
(use-package treemacs-projectile
  :straight t
  :after (treemacs projectile))
(use-package treemacs-magit
  :straight t
  :after (treemacs magit)
  :ensure t)
(use-package treemacs-icons-dired
  :straight t
  :hook (dired-mode . treemacs-icons-dired-enable-once)
  :ensure t)

However removing the hook doesn't have any impact.

I do plan to dig into this more after work but wanted to file an issue so I don't forget.

Do you have a workspace set? What is the result of (treemacs-workspace->name (treemacs-current-workspace))? If that returns nil, maybe test if this works for you:
(propertize (format " %s " (or (treemacs-workspace->name (treemacs-current-workspace)) ""))))

@sebastiaanspeck I do indeed have a workspace set

(To aide in replication if needed my entire init.el is here: https://git.gmem.ca/arch/dotfiles/src/branch/master/.emacs.d/init.el)

Maybe a backtrace could help to investigate this further? Other people reported that Treemacs is fixed with the latest patch

[gmemstr]

Debugger entered--Lisp error: (void-variable treemacs)
  treemacs--setup-mode-line()
  #<subr treemacs-mode>()
  treemacs--mode-check-advice(#<subr treemacs-mode>)
  apply(treemacs--mode-check-advice #<subr treemacs-mode> nil)
  treemacs-mode()
  treemacs--init()
  treemacs(nil)
  funcall-interactively(treemacs nil)
  command-execute(treemacs)

I'm not sure if I can get more granular than that unfortunately, I'm not super experienced with debugging elisp.

This is the issue... maybe need some help from the author of doom-modeline how to fix this?

[sebastiaanspeck]

This is a way without errors/warnings. Not sure if this is the nicest way..

Yeah my treemacs broke when adding:
(use-package doom-modeline :init (doom-modeline-mode 1) :custom ((doom-modeline-height 15)))

I had the same problem, but i run treemacs first, and then run doom-modeline, then this problem was solved.

I had the same problem, but i run treemacs first, and then run doom-modeline, then this problem was solved.

I actually have no idea how to do that with using use-package in my init.el. I tried switching the order of the respective calls around, but to no big surprise, it didn't change anything

[sebastiaanspeck]

"Fix" is merged (reverted the breaking change). Please test the latest version

right now, the rhs shows invalid. That’s because the rhs is an empty list. This looks like the perfect place to show the current workspace name. Please take a look at #1049 to see if this works for you!
