The indent_size and indent_style property does not work

[ghost]

OS: Archlinux latest.
Emacs version: 29 latest. (27 does not work too)
Plugin version: latest.

When I insert Tab, I get tab indent and wrong indent size,
But, an editorconfig file in the root of my project.

Please give me an answer! Thanks!

Thanks for reporting issue!

I want to know the result of M-x describe-editorconfig-properties and the content of your .editorconifg file.
Cloud you paste them?

Hi,

I think I have similar issue. Pressing Enter and TAB give me correct result. But running editorconfig-format-buffer, it went back to default setting

System:

• Emacs 27.2
• • Fedora 34
• • Latest editorconfig
• • CSharp mode
    editorconfig file:

[*.cs]
indent_style = space
indent_size = 3
end_of_line = lf
insert_final_newline = true

Steps to reproduce:

• Create new project
• dotnet sln new
• dotnet new classlib -o alpha
• • create .editorconfig file with above content
• • Open alpha/Class1.cs
• • Run editorconfig-format-buffer

Expected behavior:

• • Buffer is formatted with correct indent width

Actual result:

• Indent is incorrect (width 4)

Umm... I cannot reproduce your problem.

• What is the results of describe-editorconfig-properties before and after running editorconfig-format-buffer?
• What if you disable your init.el (emacs -q)? Does this problem still happen?

I forgot to mention I'm using lsp-mode.
When I disable lsp, formatting buffer worked as expected and when it is turned on, it will override everything and use value from language server.
I can get around this by setting lsp-enable-indentation to nil.

Thanks! I checked the lsp-mode code roughly.

It seems that when lsp-mode is enabled (and lsp-enable-indentation is set to t) lsp-mode configures buffers to use langauage servers' textDocument/rangeFormatting request to format buffers. So Emacs buffers' indent configurations are ignored.

IMO each language server (not lsp-mode) needs to support .editorconfig to fully solve your problem...
I'll document this to README.

My .editorconfig file:

root = true
[*]
indent_style = space
indent_size = 2
