# 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.

## Nested values
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.
```cpp
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)
int third = j.value("/list/5"_json_pointer, 0); // 0 (index out of range)
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, '.');)
{
ptr /= token;
}
return ptr;
}
int port = j.value(to_pointer("server.port"), 80); // 8080
int first = j.value(to_pointer("list.0"), 0); // 10
```
The key `#!cpp "a/b"` yields the pointer `#!cpp "/a~1b"`; the dot-splitting itself is up to the caller, so keys
containing `.` need a different separator.

a [`basic_json::type_error`](../../home/exceptions.md#jsonexceptiontype_error302), and so does a member of another

## `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
`JSON_HAS_RANGES` to `1` or `0`.
See [full documentation of `JSON_HAS_RANGES`](../api/macros/json_has_ranges.md).

When `JSON_HAS_RANGES` is enabled (and the compiler is not MinGW), a JSON array can be constructed directly from a C++20

The library detects whether the compiler supports run time type information (RTTI), which it needs, for instance, to
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).
## `JSON_HAS_STD_FORMAT`
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
for JSON values. To override the built-in check, define `JSON_HAS_THREE_WAY_COMPARISON` to `1` or `0`.

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.

Our class is heavily [unit-tested](https://github.com/nlohmann/json/tree/develop/tests/src) and covers [100%](https://coveralls.io/r/nlohmann/json) of the code, including all exceptional behavior. Furthermore, we checked with [Valgrind](http://valgrind.org) and the [Clang Sanitizers](https://clang.llvm.org/docs/index.html) that there are no memory leaks. [Google OSS-Fuzz](https://github.com/google/oss-fuzz/tree/master/projects/json) additionally runs fuzz tests against all parsers 24/7, effectively executing billions of tests so far.
