I've really come to prefer json5 as a config format: https://json5.org/ https://json5.org/ It's basically Json with comments, trailing commas, and unquoted object keys (and some other minor things). Much nicer than real json as a config format, but still simple and declarative, not requiring an interpreter or being turing-complete.
