      As a result: libraries that cross-compile to ScalaJS are in a mess and we have a new Typesafe Config wrapper library basically EVERY DAY.

      Bottom line: intentions were good, result is a mess and in many cases the features of HOCON are not even necessary.

      I have been putting config directly into Scala code for over a decade. No complaints!

      In applications, I typically use HOCON just as a passthrough to ENV vars. But in CLI apps (e.g. scalafix, scalafmt) it’s a bit different.

      For various reasons (HOCON being one of them), this happened: https://github.com/gabro/scalafmt/blob/5fc2308bb48cee681619510d4ee57d1e3ba0f482/scalafmt-jsfacade/src/main/scala/org/scalafmt/jsfacade/Config.scala#L16-L187 … It’s fixable, but it’s a bunch of hours thrown away.

      Long story, but in short: https://github.com/olafurpg/metaconfig … is currently broken on ScalaJS, so I had to improvise.

      The other part of the story is that in HOCON defaults should be in hocon not in code. Not doing that & wanting to cross-build to Scala.js...

      Yeah, we’re in a bad situation there. The principle of least power would suggest we just move to JSON in that case.

      I don't think JSON is a good language for configuration files.

      Human-editability and diffability ARE certainly quite general problems with JSON, though...

          I think they're important enough reasons to consider building another language. Also I think there are a # of other reasons/goals for hocon.

          I’ve read the document. As of today I don’t think the goals justify a new language, if you consider the ecosystem drawbacks.

          As @dwijnand said: it’s a tradeoff. JSON is also very easy to parse and doesn’t require re-inventing tooling around it.
