There are myriads of JSON libraries out there, and each may even have
|
|
its reason to exist. Our class had these design goals:
|
|
|
|
Intuitive syntax. In languages such as Python, JSON feels like a first
|
|
class data type. We used all the operator magic of modern C++ to achieve
|
|
the same feeling in your code. Check out the examples below and you'll
|
|
know what I mean.
|
|
|
|
Trivial integration. Our whole code consists of a single header file
|
|
json.hpp. That's it. No library, no subproject, no dependencies, no
|
|
complex build system. The class is written in vanilla C++11. All in all,
|
|
everything should require no adjustment of your compiler flags or
|
|
project settings.
|
|
|
|
Serious testing. Our class is heavily unit-tested and covers 100% of the
|
|
code, including all exceptional behavior. Furthermore, we checked with
|
|
Valgrind and the Clang Sanitizers that there are no memory leaks. Google
|
|
OSS-Fuzz additionally runs fuzz tests against all parsers 24/7,
|
|
effectively executing billions of tests so far. To maintain high
|
|
quality, the project is following the Core Infrastructure Initiative
|
|
(CII) best practices.
|
|
|
|
Other aspects were not so important to us:
|
|
|
|
Memory efficiency. Each JSON object has an overhead of one pointer (the
|
|
maximal size of a union) and one enumeration element (1 byte). The
|
|
default generalization uses the following C++ data types: std::string
|
|
for strings, int64_t, uint64_t or double for numbers, std::map for
|
|
objects, std::vector for arrays, and bool for Booleans. However, you can
|
|
template the generalized class basic_json to your needs.
|
|
|
|
Speed. There are certainly faster JSON libraries out there. However, if
|
|
your goal is to speed up your development by adding JSON support with a
|
|
single header, then this library is the way to go. If you know how to
|
|
use a std::vector or std::map, you are already set.
