What people are saying

I recommend the libraries from CodeSynthesis for your XML and database needs. The documentation for both is superb, and the APIs are crisp and modern. JSON I'd go with either…

I'm personally doing something similar in a C++ project that I'm working on. I designate comments with a //. When I load the JSON file, I go line by line removing comments as I find them. Once the file is parsed you can feed it into any regular JSON parser (personally I'm a fan of https://github.com/nlohmann/json). Using JSMin would have been a much better idea. At this point though the only downside is that I haven't yet done this for saving JSON. It's a harder problem but I don't see why it wouldn't also be doable. edit: Apparently this library allows you to have comments, and will even preserve them when saving the JSON file. https://github.com/open-source-parsers/jsoncpp

I recommend the libraries from CodeSynthesis for your XML and database needs. The documentation for both is superb, and the APIs are crisp and modern. JSON I'd go with either JSON Spirit (boost header dependency) or JsonCpp (git version[0], since there hasn't been a release in 3 and a half years. 1.0 was tagged recently though) For webdev I've personally used CppCMS, which is of good quality, although it is a framework and not a toolkit (it's MVC and the views want to use inheritance, has its own networking and template framework etc) [0] https://github.com/open-source-parsers/jsoncpp
