languages: add editorconfig

[nbsp]

note that this is unrelated to #279; this is simply a highlighting grammar for .editorconfig files, which i felt was useful regardless.

homepage, specification, tree-sitter grammar i wrote

Being able to highlight editorconfig syntax without support for editorconfig seems needless to me. In a pinch you can use the ini language, so I don't think we need to add another language just for this use case

[nbsp]

fair enough. should i turn this into a draft so we could look at it again when editorconfig support gets implemented?

@the-mikedavis I think adding .editorconfig to

helix/languages.toml

Line 2275 in 941dc6c

file-types = [

in the meantime, until we have support would be a net benefit for everyone. I can open a PR if needed

EditorConfig files use an INI format that is compatible with the format used by Python ConfigParser Library, but [ and ] are allowed in the section names. The section names are filepath globs, similar to the format accepted by gitignore. Forward slashes (/) are used as path separators and semicolons (;) or octothorpes (#) are used for comments. Comments should go individual lines. EditorConfig files should be UTF-8 encoded, with either CRLF or LF line separators.

It's not 100% INI but the question would be whether highlighting correctly in most cases is better than not highlighting at all until Helix supports editorconfig directly. My assumption is that the files that aren't INI compatible are rare.

(Although in all honesty I think being able to use the specific grammar in this PR even before adding official support is also a good idea)

RE: Why you'd want this without support - Shared projects use EditorConfig files often, and being able to read them highlighted is a nicer experience even if Helix doesn't yet have the functionality to support them yet IMO

INI seems like a nice compromise to me 👍. I'd like to avoid pulling in a special parser for the syntax if possible it anyways
