xenops not working with org mode 9.7.11 (Emacs 29.3)

[RaghuNaik]

I get the following error when I open an org file

> File mode specification error: (error Selecting deleted buffer) 
> Error during redisplay: (jit-lock-function 1) signaled (error "Selecting deleted buffer")

When I start emacs from the command line with emacs --debug-init after putting

(jit-lock-debug-mode 1)
(setq debug-on-error t)

in my init file, I get the following backlog trace:

Debugger entered--Lisp error: (error "Selecting deleted buffer") org-element--substring((src-block (:standard-properties [4 4 nil nil 86 1 nil planning element t nil nil nil nil #<killed buffer> nil

I had earlier reported this error to the Spacemacs team here

Is anyone else experiencing this? Thanks

I have the same problem

Hi, I'm sorry I don't have much time for xenops development. Xenops was never really intended for use with org-mode: it is intended as a standalone emacs LaTeX editor.

[fnussbaum]

I have turned my attempted fix from https://github.com/syl20bnr/spacemacs/issues/16577#issuecomment-2351643157 into a PR (https://github.com/dandavison/xenops/pull/74). It is not really tested, as I don't use xenops-mode myself. Perhaps you could try this out? @RaghuNaik @SuChengHao

@dandavison Of course feel free to disregard this if you prefer to not support Org anymore. I have also opened #75 which fixes a minor annoyance I had when trying to test #74.

[RaghuNaik]

Thanks @fnussbaum. I did test out the fix. It does not solve the issues. Though the errors go away, equations are not processed and formatted now. Also emacs freezes on startup immediately after introducing the fix.
