Properties not automatically applied and indent_style not respected on vanilla GNU Emacs 30.2

[bbergeron0]

I'm using stock GNU Emacs 30.2, with only the single following line added to ~/.config/emacs/init.el:

(editorconfig-mode 1)

When I open a file that's right next to an .editorconfig file, M-x editorconfig-display-current-properties returns "Properties are not applied to current buffer yet." Only running M-x editorconfig-apply applies said properties and allows the previous command to show me the editorconfig properties.

That's a problem in itself, but the more serious issue is that even after applying these properties, Emacs doesn't seems to respect indent_style (e.g. When I press <tab> to indent, I get spaces instead of a tab character).

• I've deleted the ~/.cache/emacs folder.
• I've tried with .c, .js and .prolog files, and the properties are not automatically applied for any of these. Even after applying them manually, <tab> still inserts spaces.

.editorconfig

root = true

[*]
end_of_line = lf
insert_final_newline = true
charset = utf-8
indent_style = tab
trim_trailing_whitespace = true

Output of M-x editorconfig-display-current-properties

(After doing M-x editorconfig-apply)

# EditorConfig for /home/bbergeron/Projects/coinflip/coinflip.c
end_of_line = lf
insert_final_newline = true
charset = utf-8
indent_style = tab
trim_trailing_whitespace = true

System Info:

• Artix Linux (not using any third-party package repository)
• GNU Emacs 30.2

I also tried with GNU Emacs 30.2 on Gentoo, and it's not working either.

EDIT: This issue was initially about no properties being respected at all; however, this was only the case when using evil-mode during my first tests. I subsequently changed my settings without tracking the sequence of these tests. What is certain is that the properties are not applied automatically, and indent_style is not being respected.

You haven't set indent_size = tab in your editorconfig file, so you'll likely be mixing tabs with an indent size that is not the same as the default tab width.

E.g. if the tab width is 8 and you're indenting to column 4, that can only be done with spaces.

If that's your problem, it's expected behaviour, and you simply need to update your editorconfig file.

I cannot reproduce any other problems -- if you can, please verify whether you've tested with emacs -Q (to inhibit your config -- if you don't see the same issues that way, you'll know that something in your config is conflicting/clobbering the settings).
