We currently implement the parser as naive [recursive descent parser](http://en.wikipedia.org/wiki/Recursive_descent_parser) with hand coded string handling. It is fast enough, but a [LALR-parser](http://en.wikipedia.org/wiki/LALR_parser) with a decent regular expression processor should be even faster (but would consist of more files which makes the integration harder). +See the [https://github.com/nlohmann/json/blob/master/CONTRIBUTING.md#please-dont](contribution guidelines) for more information. + ## Integration The single required source, file `json.hpp` is in the `src` directory or [released here](https://github.com/nlohmann/json/releases).

Over time, people actually started to use the JSON library (yey!) and started to help improve it by proposing features, finding bugs, or even fixing my mistakes. I am really [thankful](https://github.com/nlohmann/json/blob/master/README.md#thanks) for this and try to keep track of all the helpers.
