# NLOHMANN_JSON_NAMESPACE_NO_VERSION
|
|
|
|
```cpp
|
|
#define NLOHMANN_JSON_NAMESPACE_NO_VERSION /* value */
|
|
```
|
|
|
|
If defined to `1`, the version component is omitted from the inline namespace. See
|
|
[`nlohmann` Namespace](../../features/namespace.md#structure) for details.
|
|
|
|
## Default definition
|
|
|
|
The default value is `0`.
|
|
|
|
```cpp
|
|
#define NLOHMANN_JSON_NAMESPACE_NO_VERSION 0
|
|
```
|
|
|
|
When the macro is not defined, the library will define it to its default value.
|
|
|
