```
|

|

1. Inserts `value` if no element with an equal key already exists (per [`key_compare`](key_compare.md)),
|
||||
appending it at the end to preserve insertion order. If an equal key already exists, does nothing.
|
||||
2. Inserts the elements from range `[first, last)`, in iteration order, applying the same equal-key rule

as (1) to each element.

|

|

## Return value
|

|

1. pair of an iterator to the (possibly newly inserted) element, and a `bool` that is `true` if insertion

## Complexity

using key_compare = std::equal_to<Key>; // until C++14

using key_compare = std::equal_to<>; // since C++14
|

```
|
||||
|
||||
The comparator used to determine key equality when looking up elements. Unlike `std::map`, `ordered_map`
|
||||
uses linear search with `key_compare` rather than an ordering relation, since element order reflects
|
||||
insertion order rather than key order.
|
||||
|
||||
Since C++14, the transparent `#!cpp std::equal_to<>` is used, which enables heterogeneous lookup (e.g.
|
||||
looking up by a `#!cpp const char*` key without constructing a temporary `Key`).

A tuple type may also hold references (e.g. `#!cpp std::tuple<double&, std::string&>`) to avoid copying: `get`
|

then returns a tuple of references pointing directly at the elements stored inside the `basic_json` array,

A referenced type must be one the library actually stores (or an arithmetic type it can convert to/from);

||||
otherwise this is a compile error.

A `json` array can also be constructed directly from a C++20 range view (`std::ranges::view`), such as the result

of `std::views::filter` or `std::views::transform` -- no intermediate container is needed:

Enable [extended diagnostic messages](../home/exceptions.md#extended-diagnostic-messages) by defining macro [`JSON_DIAGNOSTICS`](../api/macros/json_diagnostics.md). This option is `OFF` by default.
|
||||
|
||||
!!! warning "Does not apply to a pre-installed package"
|
||||
|
||||
This option only takes effect when building nlohmann/json from source as part of your own
|
||||
CMake project (e.g. via [`FetchContent`](#fetchcontent) or [`add_subdirectory`](#external)).
|
||||
It has **no effect** on a package that was already built and installed elsewhere (Homebrew,
|
||||
vcpkg, a system package, etc.) — the resulting compile definition is baked into the exported
|
||||
`nlohmann_jsonTargets.cmake` at install time, and `set(JSON_Diagnostics ON)` before
|
||||
`find_package()` does not change it (verified against the Homebrew-installed package: the
|
||||
exported target still carries a fixed `$<$<BOOL:OFF>:JSON_DIAGNOSTICS=1>`, regardless of any
|
||||
variable set in the consuming project).
|
||||
|
||||
To enable extended diagnostics for a pre-installed package, override the imported target's
|
||||
property directly after `find_package()`:
|
||||
|
||||
```cmake
|
||||
find_package(nlohmann_json REQUIRED)
|
||||
set_target_properties(nlohmann_json::nlohmann_json PROPERTIES
|
||||
INTERFACE_COMPILE_DEFINITIONS "JSON_DIAGNOSTICS=1")
|
||||
```
|
||||
|
||||
This only works cleanly when your project is the sole consumer of that imported target. If
|
||||
nlohmann_json is pulled in from more than one place in your dependency graph with different
|
||||
`JSON_DIAGNOSTICS` values, you may see a `"JSON_DIAGNOSTICS" redefined` compiler error, since
|
||||
conflicting `-D` flags can end up on the same compile command line.
|
||||
|
||||
### `JSON_Diagnostic_Positions`
|
||||

||||
Enable position diagnostics by defining macro [`JSON_DIAGNOSTIC_POSITIONS`](../api/macros/json_diagnostic_positions.md). This option is `OFF` by default.
