The following areas really need contribution: The following areas really need contribution:
- Getting the code to compile without errors with the latest **Microsoft Visual Studio** version. I am not using Windows, so I cannot debug code with MSVC myself. There is a job on [AppVeyor](https://ci.appveyor.com/project/nlohmann/json) though. - Extending the **continuous integration** toward more exotic compilers such as Android NDK, Intel's Compiler, or the bleeding-edge versions of GCC or Clang.
- Extending the **continuous integration** beyond Linux running some versions of GCC and Clang on [Travis](https://travis-ci.org/nlohmann/json) and Microsoft Visual Studio on [AppVeyor](https://ci.appveyor.com/project/nlohmann/json). We have found a lot of bugs just because several compilers behave in a slightly different manner.
- Improving the efficiency of the **JSON parser**. The current parser is implemented as a naive recursive descent parser with hand coded string handling. More sophisticated approaches like LALR parsers would be really appreciated. That said, parser generators like Bison or ANTLR do not play nice with single-header files -- I really would like to keep the parser inside the `json.hpp` header, and I am not aware of approaches similar to [`re2c`](http://re2c.org) for parsing. - Improving the efficiency of the **JSON parser**.

- Extending and updating existing **benchmarks** to include (the most recent version of) this library. Though efficiency is not everything, speed and memory consumption are very important characteristics for C++ developers, so having proper comparisons would be interesting. - Extending and updating existing **benchmarks** to include (the most recent version of) this library.

- Check the code with [**Coverity**](https://scan.coverity.com).
- Make the code **locale-independent**. The library currently only works for a locale where `.` is the decimal point character.

## Supported compilers :beer: If you are using OS X and [Homebrew](http://brew.sh), just type `brew tap nlohmann/json` and `brew install nlohmann_json` and you're set. If you want the bleeding edge rather than the latest release, use `brew install nlohmann_json --HEAD`.
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++ 14.0 RC (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
```
- 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.

### 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
