Strange behaviour for the help on key bindings #15548

Closed DrWaleedAYousef closed 7 months ago

DrWaleedAYousef commented 2 years ago

Description :octocat:

The C-h k command does not work with any key binding and gives the message: mapcar: Symbol’s value as variable is void: code-cells-mode

Clue Is this relatd to the strange behavior of the key bindings mentioned in issue #15479 ?

EDIT The problem exists even when I commented everything inside (defun dotspacemacs/user-config () and my layer definition is:

BenedictHW commented 2 years ago

Dr,

I have a feeling this may be due to your config. I am unable to reproduce the bug from my Spacemacs. Usually when "Symbol's value as variable is void" that means said symbol is undefined. Sometimes wrapping the relevant code in a "with-eval-after-load" macro solves the issue if the symbol is only undefined at a certain point in time.

I would check that whatever package code-cells-mode has been successfully loaded. Do other symbols in the same package show up when you "C-h f" function names or "C-h v" variable names? Instead of the "C-h k" command try removing helm-descbinds with the following in your dotspacemacs/layers,

(helm :packages (not helm-descbinds))

And then "C-h b". will give you the loaded keymaps for a particular buffer and its respective modes. Has code-cells-mode's keymaps listed? Does "C-h m" show code-cells-mode under it's minor modes?

As an aside, I use https://github.com/nnicandro/emacs-jupyter which has been able to connect to both the wolfram kernel and sagemath.

HTH,

jgrosso commented 2 years ago

I am also having this issue, except for me it's that string-edit-mode is void.

thanhvg commented 2 years ago

Did you update the packages yet?

jgrosso commented 2 years ago

Yup, as recently as this morning (as well as pulling the latest .emacs.d). If it's helpful , the error used to be about code-cells-mode for me too, but then it changed to string-edit-mode after I updated packages/Spacemacs a few days ago.

jgrosso commented 2 years ago

(I just reset to an old develop commit, but the issue is still there, so I suspect the issue might be in the packages or my own config.)

DrWaleedAYousef commented 2 years ago

I still will reply @BenedictHW; meanwhile, I update almost daily. This problem seems to reflect on gnus behaviour as I indicated (not very sure)

thanhvg commented 2 years ago

code-cells-mode is from python layer' s code-cells package. Do you have any customization in your dotspacemacs/user-config?

DrWaleedAYousef commented 2 years ago

I updated the issue above to reflect my current configurations. I commented everything inside the user configuration function. The problem is still there.

DrWaleedAYousef commented 2 years ago

Oh; one more thing. Just now, after I updated the issue above, I tried to comment out the python layer:

     ;; (python :variables
     ;;         python-format-on-save t
     ;;         python-formatter 'yapf ;; default is lsp
     ;;         python-fill-column 99
     ;;         python-backend 'lsp
     ;;         python-lsp-server 'pyright
     ;;         )

The problem is gone! However, gnus' problems are the same!

tko commented 2 years ago

I had similar problem with code-cells. After tinkering with some things I came up with patch I forgot to send that seems to have fixed the issue.

IIRC the main issue was with :init vs. :config and the other bits are needed to declare the dependencies properly for :config . maybe there's similar issue with string-edit-mode

I encountered the same error mapcar: Symbol’s value as variable is void: code-cells-mode.

Applying the above patch can resolve it. Thanks a lot, @tko!

xuan-w commented 2 years ago

I also have this problem. Since I don't use code-cells, I removed it and everything is fine.

ir210 commented 1 year ago

@jgrosso I believe you are using Emacs 29. In that case, if you don't need string-edit (SPC x e), you can simply put string-edit into the dotspacemacs-excluded-packages list.

The reason for that is that Emacs added a new built-in package called string-edit in 29 and this is an entirely different package than what Spacemacs uses for "SPC x e". There is a package naming collision here.

See: https://github.com/magnars/string-edit.el/issues/19

lebensterben commented 1 year ago

@ir210

Thanks for the information. I will make a workaround to turn of string-edit on Emacs 29
