A Case for JSON6

2025-04-19T06:43:00+03:00

Just a required follow up for the previous post: JSON5 sucks too, like any other possible format. Just look at this:

{
    certificate: "\
-----BEGIN PRIVATE KEY-----\n\

}

Is JSON5 a better JSON?

Yes it is, at least when it comes to configuration files.

As I said earlier, JSON is a good serialization language but a terrible config language. JSON5 builds on its strong sides: it's backwards compatible with JSON and is still a subset of JavaScript and it is still relatively easy to parse. Then it adds all the good stuff like unquoted keys, trailing commas, and a must-have thing for any config, comments. For me it has only two real downsides, both really minor. First is, as most config-oriented languages, it's tricky for automated modification, a feature it shares with TOML and YAML. The second one is JSON6, while ES6 syntax sugar is nice, it's just a 15th competing standard, and the worst, competing with itself.

On Common Misuse of the File Formats

A small rant about text file format holy wars. I believe that most of the file formats that participate in these holy wars are rather good and the most of the frustration comes from their misuse.
