Niels Lohmann 8418ff85b6 Document what counts as a breaking change in the API stability rules
Spell out the 3.x compatibility rules in the roadmap: new defaulted
parameters, new default arguments, noexcept/constexpr, template
parameters, parse and dump results, accepted input, key iteration order,
iterator invalidation, implicit conversions, to_json/from_json lookup,
json_sax, value_t enumerators, and documented macros, CMake options and
headers. Also list std::hash values as not part of the public API, and
link the macro overview from the section.

The following areas really need contribution and are always welcomed:
- Extending the **continuous integration** toward more exotic compilers such as Android NDK, Intel's Compiler, or the
bleeding-edge versions of Clang.
- Improving the efficiency of the **JSON parser**. The current parser is a hand-written iterative parser that keeps an
explicit stack instead of recursing, with hand-coded string handling. Speeding up the lexer or the value construction
would be appreciated. Parser generators like Bison or ANTLR do not play nice with single-header files -- I really

is not everything, speed and memory consumption are very important characteristics for C++ developers, so having
proper comparisons would be interesting.

Please note:
- GCC 4.8 has a bug [57824](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57824): multiline raw strings cannot be the arguments to macros. Don't use multiline raw strings directly in macros with this compiler.
- For GCC running on MinGW or Android, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod` or `strtof`) may occur. Note this is not an issue with the code, but rather with the compiler or C++ standard library itself: use a recent toolchain (for Android, a current [NDK](https://developer.android.com/ndk) with the LLVM C++ library `APP_STL := c++_shared`, and for MinGW, a distribution with a complete C++11 standard library). See [this discussion](https://github.com/nlohmann/json/issues/136) for MinGW and [this discussion](https://github.com/nlohmann/json/issues/219) for the old Android NDK using `APP_STL := gnustl_static`.
- 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.
```makefile
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` or `strtof`) 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](https://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).
- Unsupported versions of GCC and Clang are rejected by `#error` directives. This can be switched off by defining `JSON_SKIP_UNSUPPORTED_COMPILER_CHECK`. Note that you can expect no support in this case.

Some tests change the installed files and hence make the whole process not reproducible. Please execute `ctest -LE not_reproducible` to skip these tests. See [issue #2324](https://github.com/nlohmann/json/issues/2324) for more information. Furthermore, assertions must be switched off to ensure reproducible builds (see [discussion 4494](https://github.com/nlohmann/json/discussions/4494)).
Note you need to call `ctest -LE "not_reproducible|git_required"` to exclude both labels. See [issue #2596](https://github.com/nlohmann/json/issues/2596) for more information.

As Intel compilers use unsafe floating point optimization by default, the unit tests may fail. Use flag [`/fp:precise`](https://www.intel.com/content/www/us/en/docs/cpp-compiler/developer-guide-reference/2021-8/fp-model-fp.html) then.

# JSON_HAS_RANGE_VIEW_CONVERSION
```cpp
#define JSON_HAS_RANGE_VIEW_CONVERSION /* value */
```
This macro indicates whether a JSON array can be constructed directly from a C++20 range view (`std::ranges::view`),
such as the result of `std::views::filter` or `std::views::transform`. Possible values are `1` when supported or `0`
when unsupported.
## Default definition
The default value is `1` if [`JSON_HAS_RANGES`](json_has_ranges.md) is `1` and the compiler is not MinGW (that is,
`#!cpp __MINGW32__` is not defined), and `0` otherwise.
When the macro is not defined, the library will define it to its default value.
!!! info "Known compiler/stdlib exclusions"
- **MinGW** -- disabled, because its `std::ranges` support is incomplete ([issue #4916](https://github.com/nlohmann/json/issues/4916)).
- All toolchains for which [`JSON_HAS_RANGES`](json_has_ranges.md#default-definition) is disabled.
## Examples

To read a value deep inside a document, pass a [JSON Pointer](../json_pointer.md) instead of a key. The default value is
returned if the value at the pointer does not exist, including the case that an intermediate key is missing. There is
no need to check each level with [`contains`](../../api/basic_json/contains.md) first.

json j = {{"server", {{"port", 8080}}}, {"list", {10, 20}}};
int port = j.value("/server/port"_json_pointer, 80); // 8080
int timeout = j.value("/server/limits/timeout"_json_pointer, 30); // 30 (missing intermediate key)
int second = j.value("/list/1"_json_pointer, 0); // 20 (numeric tokens index arrays)

bool has_port = j.contains("/server/port"_json_pointer); // true
bool has_host = j.contains("/server/host/name"_json_pointer); // false
```
If the path is only available as a dotted string such as `#!cpp "server.port"`, do not build the pointer by
concatenating `#!cpp "/"` and the parts: keys containing `/` or `~` would be misinterpreted. Append each part as a
reference token with [`operator/=`](../../api/json_pointer/operator_slasheq.md) instead. It escapes the token for you.
```cpp
json::json_pointer to_pointer(const std::string& dotted)
{
json::json_pointer ptr;
std::istringstream in(dotted);
for (std::string token; std::getline(in, token, '.');)
{

}

}

## `JSON_HAS_RANGES`
The library uses `std::ranges` (and concepts) where available, for example, to parse from C++20 ranges and to
construct JSON arrays from range views. The library detects whether the standard library supports ranges and
disables the support on toolchains with an incomplete implementation. To override the built-in check, define

exclude `std::any` from the candidate types of the implicit conversion on C++17. To override the built-in check, define
`JSON_HAS_STATIC_RTTI` to `1` or `0`.
See [full documentation of `JSON_HAS_STATIC_RTTI`](../api/macros/json_has_static_rtti.md).

When compiling with C++20 and a standard library that provides `<format>`, the library provides a `std::formatter`
specialization for JSON values. To override the built-in check, define `JSON_HAS_STD_FORMAT` to `1` or `0`.
See [full documentation of `JSON_HAS_STD_FORMAT`](../api/macros/json_has_std_format.md).
## `JSON_HAS_THREE_WAY_COMPARISON`
When the compiler and standard library support 3-way comparison (the spaceship operator `<=>`), the library provides it

## Merging objects
To merge one object into another, [`update`](../api/basic_json/update.md) copies all members from another object
(similar to Python's `dict.update`). This is the idiomatic way to combine two objects. It has two modes:
- By default, the merge is shallow: existing keys are overwritten, even if both values are objects.
- With `merge_objects = #!cpp true`, keys whose values are objects in both JSON values are merged recursively.
Everything else is overwritten. In particular, arrays are replaced, not concatenated.

are kept:

json user_settings = {{"log", {{"level", "debug"}}}};

documents (e.g., received via HTTP PATCH). To merge configuration-like objects, use `#!cpp update(..., true)`. To apply

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.

An integer number cannot be represented by the binary format it is serialized to:
This exception previously indicated that the UBJSON and BSON binary formats did not support integer numbers greater than
9223372036854775807 due to limitations in the implemented mapping. However, these limitations have since been resolved,
and this exception no longer occurs.
- [BON8](../features/binary_formats/bon8.md) only stores integers that fit into int64.
- [CBOR](../features/binary_formats/cbor.md), [MessagePack](../features/binary_formats/messagepack.md), and
[BSON](../features/binary_formats/bson.md) store integers in at most 64 bits. With the default number types, every
integer fits, but a [`number_integer_t`](../api/basic_json/number_integer_t.md) or
[`number_unsigned_t`](../api/basic_json/number_unsigned_t.md) wider than 64 bits (e.g., `__int128`) can hold values
outside the range of the format: [-2^64, 2^64-1] for CBOR, [-2^63, 2^64-1] for MessagePack, and the range of int64
(signed integers) or uint64 (unsigned integers) for BSON.
!!! success "Exception cannot occur any more"
[UBJSON](../features/binary_formats/ubjson.md) and [BJData](../features/binary_formats/bjdata.md) never throw this

!!! note
Before version 3.13.0, CBOR, MessagePack, and BSON silently truncated integers wider than 64 bits, and BJData
truncated unsigned integers wider than 64 bits. This exception was previously thrown by UBJSON and BSON for
integers greater than 9223372036854775807; since version 3.9.0, such integers are serialized as high-precision
UBJSON numbers, and since version 3.12.0 as uint64 BSON numbers.
