Unable to exclude editorconfig from org-mode in emacs 30.1 on debian 13.1 "trixie"

[steinarb]

Platform: debian 13.1 "trixie", amd64
Editorconfig version: melpa 20250809.139
Emacs version: GNU Emacs 30.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.49, cairo version 1.18.4) of 2025-07-18, modified by Debian

I have a conflict with editorconfig and org-mode so I am trying to exclude editorconfig from .org files and have the following config in my .emacs:

(when (locate-library "editorconfig")
  (editorconfig-mode 1)
  (setq editorconfig-exclude-regexps '("\\.jar$" "\\.org$")))

But the setting doesn't seem to have any effect in editorconfig 20250809.139. I get a problem when pressing TAB to toggle visibility of hidden views in org-mode.

I see that back in august 13 2024 editorconfig-exclude-regexps worked for excluding jar files but in the current version it does not work for excluding .org files.

A datapoint is that it just seems to be a problem in my README org files, such as e.g.
https://github.com/steinarb/frontend-karaf-demo/blob/master/README.org

Maybe it has something to with the uppercase "README"...? (just guessing here)

Side note: editorconfig-mode is included in Emacs-30, but that version does not support editorconfig-exclude-regexps at all, so I'm curious to know what the conflict is about (maybe it's offtopic here, in which case, feel free to reply by email).

The underlying conflict between editorconfig-emacs and org-mode was AFAIK fixed on main HEAD org-mode by @yantar92 back in March 2025, but is not fixed in the 30.1 bundled org-mode (which is what I first tried using after upgrading to debian 13 "trixie". Now I'm back on git clone org-mode which is what I was using with emacs 30.1 from backports in debian 12.x "bookworm")

This fix, I think...? bzg/org-mode@0dc647f

Ah, thanks. So the problem was not specific to editorconfig (it applied also to `dir-locals.el`, tho in practice probably much more rarely). Also, in Emacs-30's version of `editorconfig-mode` the problem should hopefully be a bit less common because `tab-width` is set only if `tab_width` setting is specified or if the `indent_style` is set to "tab". But yeah, the editconfig spec is screwed up w.r.t its conflation of "tab width" and "indentation size".

Ah! I just thought of a possible reason the problem this time only seemed to affect the README.org files of my projects: the projects actually have an .editorconfig file, while the git repos containing org files used for various notes do not have .editorconfig files.

Here is the .editorconfig file of the project with the README.org referenced in the initial issue report (where TAB expansion of hidden org element created an error message): https://github.com/steinarb/frontend-karaf-demo/blob/master/.editorconfig

(i.e. spaces not tabs, and 4 space indent)

(all of my software projects have more or less identical .editorconfig files, decided on in 2017, when I first started using editorconfig in eclipse and emacs, and stayed with since then)

But the fact that the problem occurs means that exclude of .org files does not work in the melpa version of editorconfig I am currently using, so this github issue with the current title is still correct: exclusion doesn't work

(It does means that my first guess at why exclusion doesn't work is probably wrong, though. Doesn't necessarily have anything to do with upper case file names. Editorconfig isn't excluded for any .org files, but the bug that made me discover they aren't excluded only occurs on projects with .editorconfig files)

OK, I assume that the problem disappears if you remove the melpa package and rely on the `editorconfig-mode` that's bundled in Emacs≥30 instead.

Looks like it, yes.

I removed the editorconfig melpa package, by doing 'M-x package-list-packages', marking the installed editorconfig package with 'd' and then pressing 'x'.

I then did mv ~/git/org-mode/ ~/git/org-mode-disabled (so that git org-mode is removed from load-path).

I then started emacs with built-in editorconfig and org-mode

emacs ~/workspaces/ws01/frontend-karaf-demo/README.org

and I can confirm that the TAB problem isn't present (so I will run with this combo going forward: native editorconfig and native org-mode).
