global-writeroom-mode breaks org mode export scope

[B4rc1]

When using (global-writeroom-mode) in my config.el and try to export with the scope of org mode changed to subtree, (hitting C-s during the export prompt) org just displays Args out of range: 1, 1 in my statusbar and does not produce any file.
I have confirmed that i can export only the subtree by using writeroom-mode manually.
I have tested this with emacs 27.1 and a bunch of 28 versions with and without native comp.
I have experienced this on FreeBSD, on Arch and on Fedora 33.
I use doom emacs, in case that's relevant.

[joostkremers]

I can't seem to reproduce this on Emacs 27. Would it be possible to produce a backtrace (M-x toggle-debug-on-error RET and then trigger the error) and post it here? That might be helpful.

This is strange... line-number-display-width is called once in writeroom-mode. It's called without argument, but that should be fine, because its single argument is optional.

I've gone through the following procedure with emacs -Q (actually, I'm using the Emacs sandbox script because it preconfigures Melpa):

• Install writeroom-mode.
• Open an IELM buffer and do (require 'writeroom-mode).
• Set writeroom-major-modes to (org-mode text-mode).
• Do M-x global-display-line-numbers-mode RET.
• Do M-x global-writeroom-mode RET.
• Open an .org file (this activates writeroom-mode).
• Move point to some subtree.
• C-c C-e (org-export-dispatch).
• C-s to change the scope.
• h h to export to an HTML file.

This all works without issue. I'm using Emacs 27.1.91.

I also tried exporting to a LaTeX file (which I gather from the backtrace is what you're doing), but that also works fine.

So, yes, I'm beginning to suspect that Doom may have something to do with this. I took a quick look at the code that Doom adds, but there doesn't seem to be anything that might be problematic.

If you can reproduce the problem with emacs -Q (without Doom), please let me know. Otherwise you'll probably need to raise this issue with the Doom maintainers. If you do, feel free to mention me, so that I'm made aware of the thread and can join in if needed.
