EditorConfig Support

[ghost]

This would probably be a bit of work, but would certainly be a nice-to-have. I think Qt supports this type of config file as well, so hopefully that'd reduce the required work.

In case anyone is unfamiliar, this is EditorConfig.

I think it's easy to use QSettings and apply the settings to the editor by yourself.

[ghost]

Right, it supports the file format. But why have everyone else implement this feature instead of just adding it to the library?

[ouuan]

I think you mean providing a preference window, but your application may have a preference window, and it's strange to have two.

[ouuan]

I think using QSettings is not much harder than calling the responding functions like setTabReplaceSize(), so I believe you mean the preference window.

[ghost]

I don't mean having a preference window, I just mean a function like this:

QCodeEditor::loadEditorConfig(const char* filename) {
  /* here */
}

The file is not really a user settings file. It's dropped into git repositories to help consistency in the project's indentation style.

Oh, is that something like .clang-format? Sorry for that, I didn't read https://editorconfig.org/. However, the name "EditorConfig" is really confusing.

[ouuan]

So (how) is EditorConfig better than Clang Format?

[ghost]

Yes, it's very similar to .clang-format. No worries!

I wouldn't say that it's better. I've only ever used clang-format passively, in a formatting script. EditorConfig is usually integrated into a code editor so that it actively maintains the indentations as they are written. I'm sure there's some plugins that support this from a .clang-format file, but I don't really use them.

If there's anything .editorconfig definitely does better than .clang-format, it's that it's much simpler and easier to put into an existing editor. Trying to integrate .clang-format, on the other hand, requires either supporting the many different versions of the clang libraries or implementing all the rules found in the .clang-format file.
