## Supported compilers
|
||||
|
||||
Though it's 2016 already, the support for C++11 is still a bit sparse. Currently, the following compilers are known to work:
|
||||
|
||||
- GCC 4.9 - 6.0 (and possibly later)
|
||||
- Clang 3.4 - 3.9 (and possibly later)
|
||||
- Microsoft Visual C++ 2015 / 14.0 (and possibly later)
|
||||
|
||||
I would be happy to learn about other compilers/versions.
|
||||
|
||||
Please note:
|
||||
|
||||
- GCC 4.8 does not work because of two bugs ([55817](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55817) and [57824](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57824)) in the C++11 support. Note there is a [pull request](https://github.com/nlohmann/json/pull/212) to fix some of the issues.
|
||||
- Android defaults to using very old compilers and C++ libraries. To fix this, add the following to your `Application.mk`. This will switch to the LLVM C++ library, the Clang compiler, and enable C++11 and other features disabled by default.
|
||||
|
||||
```
|
||||
APP_STL := c++_shared
|
||||
NDK_TOOLCHAIN_VERSION := clang3.6
|
||||
APP_CPPFLAGS += -frtti -fexceptions
|
||||
```
|
||||
|
||||
The code compiles successfully with [Android NDK](https://developer.android.com/ndk/index.html?hl=ml), Revision 9 - 11 (and possibly later) and [CrystaX's Android NDK](https://www.crystax.net/en/android/ndk) version 10.
|
||||
|
||||
- For GCC running on MinGW or Android SDK, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod`) may occur. Note this is not an issue with the code, but rather with the compiler itself. On Android, see above to build with a newer environment. For MinGW, please refer to [this site](http://tehsausage.com/mingw-to-string) and [this discussion](https://github.com/nlohmann/json/issues/136) for information on how to fix this bug. For Android NDK using `APP_STL := gnustl_static`, please refer to [this discussion](https://github.com/nlohmann/json/issues/219).

|

|

|
||||
### STL-like access
|
||||
|
||||
We designed the JSON class to behave just like an STL container. In fact, it satisfies the [**ReversibleContainer**](http://en.cppreference.com/w/cpp/concept/ReversibleContainer) requirement.

### Conversion from STL containers
|
||||
|
||||
Any sequence container (`std::array`, `std::vector`, `std::deque`, `std::forward_list`, `std::list`) whose values can be used to construct JSON types (e.g., integers, floating point numbers, Booleans, string types, or again STL containers described in this section) can be used to create a JSON array. The same holds for similar associative containers (`std::set`, `std::multiset`, `std::unordered_set`, `std::unordered_multiset`), but in these cases the order of the elements of the array depends how the elements are ordered in the respective STL container.

|
||||
### JSON Pointer and JSON Patch
|
||||
|
||||
The library supports **JSON Pointer** ([RFC 6901](https://tools.ietf.org/html/rfc6901)) as alternative means to address structured values. On top of this, **JSON Patch** ([RFC 6902](https://tools.ietf.org/html/rfc6902)) allows to describe differences between two JSON values - effectively allowing patch and diff operations known from Unix.
|
||||
|
||||
```cpp
|
||||
// a JSON value
|
||||
json j_original = R"({
|
||||
"baz": ["one", "two", "three"],
|
||||
"foo": "bar"
|
||||
})"_json;
|
||||
|
||||
// access members with a JSON pointer (RFC 6901)
|
||||
j_original["/baz/2"_json_pointer];
|
||||
// "two"
|
||||
|
||||
// a JSON patch (RFC 6902)
|
||||
json j_patch = R"([
|
||||
{ "op": "replace", "path": "/baz", "value": "boo" },
|
||||
{ "op": "add", "path": "/hello", "value": ["world"] },
|
||||
{ "op": "remove", "path": "/foo"}
|
||||
])"_json;
|
||||
|
||||
// apply the patch
|
||||
json j_result = j_original.patch(j_patch);
|
||||
// {
|
||||
// "baz": "boo",
|
||||
// "hello": ["world"]
|
||||
// }
|
||||
|
||||
// calculate a JSON patch from two JSON values
|
||||
json::diff(j_result, j_original);
|
||||
// [
|
||||
// { "op":" replace", "path": "/baz", "value": ["one", "two", "three"] },

// { "op":"remove","path":"/hello" },

||||
// { "op":"add","path":"/foo","value":"bar" }
|
||||
// ]
|
||||
```
|
||||
|
||||
|
||||
### Implicit conversions
|
||||
|
||||
The type of the JSON object is determined automatically by the expression to store. Likewise, the stored value is implicitly converted.
|
||||
|
||||
```cpp
|
||||
/// strings
|
||||
// strings
|
||||
std::string s1 = "Hello, world!";

Thanks a lot for helping out!

## Notes
|
||||
|
||||
- The code contains numerous debug **assertions** which can be switched off by defining the preprocessor macro `NDEBUG`, see the [documentation of `assert`](http://en.cppreference.com/w/cpp/error/assert).
|
||||
- As the exact type of a number is not defined in the [JSON specification](http://rfc7159.net/rfc7159), this library tries to choose the best fitting C++ number type automatically. As a result, the type `double` may be used to store numbers which may yield [**floating-point exceptions**](https://github.com/nlohmann/json/issues/181) in certain rare situations if floating-point exceptions have been unmasked in the calling code. These exceptions are not caused by the library and need to be fixed in the calling code, such as by re-masking the exceptions prior to calling library functions.
