.editorconfig with empty values

[Vampire]

When you export a code style config from IntelliJ to an .editorconfig file, there are several keys without value. This makes the ktlint plugin 0.20.0-beta-4 not work anymore as it gets a parse exception from ec4j:

2023-12-01 16:51:13,882 [1216094]   INFO - STDOUT - Start ktlintFormat on file '....kt' triggered by 'KtlintPostFormatProcessor'

Thanks for the report, @Vampire.

The editorconfig format specification is quite clear about the alowed structures in .editorconfig files:

Each line must be one of the following: ...

• Key-Value Pair (or Pair): contains a key and a value, separated by an =.
  • Key: The part before the first = (trimmed of whitespace, but including any whitespace in the middle).
  • Value: The part after the first = (trimmed of whitespace, but including any whitespace in the middle). Any line that is not one of the above is invalid.

I'd interpret it in such a way that keys without values are illegal and it is the IJ export that should be fixed.

I don't see how a value of "" (empty string) is not following that specification. "Fixing" the IJ export is not as simple as it might sound, because it is also the interpretation. A key with empty value is different from the key being absent.

I have filed a specs clarification issue https://github.com/editorconfig/editorconfig/issues/496

[Vampire]

Soooo, the specification now is clarified by explicitly allowing empty values. Can we get a fix for this now? :-)
