Sublime Text uses JSON for settings. As a user, I've never been unhappy with that. Their JSON parser handles comments fine because each setting is accompanied by one. // When enabled, hovering over a word will show a popup listing all // possible locations for the definition symbol. Requires index_files. "show_definitions": true, The author does highlight an important point though: if you're using JSON for your program's config and your program's parser doesn't support comments, you may want to find a parser that does. The author also mentions readability, which I think is subjective. I find JSON plenty readable provided key names are descriptive and the JSON is well-formatted. Readability does suffer when you have multiple nested objects. I'll also agree to the annoyances of forgetting a trailing comma somewhere.
