If you need someone to try it out please let me know and I'll give it a spin. Good luck on your library. Cheers,

And then you can use attributes to get it to fill structs with data, but that's too basic for my needs.

One that doesn't just load the file and build a data structure that represents the whole thing. So not std.json, at least. Are you asking for a SAX-styled parser for JSON? Similarly - what would you like to see from a full-featured JSON module? For context: I'm currently (very slowly) working on a -betterC library. The JSON lexer is able to work off of buffered data streams instead of flat in-memory arrays. So even if what you're looking for doesn't exist right now, I'd like to try and (again; very slowly) change that.

Unfortunately a massive downside for D is the fact that the ecosystem is very small when compared to other languages such as Java. You might want to try the following: https://github.com/libmir/asdf

Is there such a JSON parser?
I need to parse some JSON data into various data structures, so I'm looking for a parser based on events or ranges. One that doesn't just load the file and build a data structure that represents the whole thing. So not std.json, at least.
