## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.7/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

> **Warning:**
>
> **Deprecated.** serializeInlineMappingsOnOneLine is deprecated. Unity now always serializes inline mappings on one line. This property always returns true.

```csharp
public static bool serializeInlineMappingsOnOneLine { get; set; }
```

### Remarks

This property is deprecated. Unity now always writes references and similar YAML structures on one line to reduce version control noise. The property always returns `true` and setting it has no effect.

Unity always serializes inline mappings like this:

`m_MySerializedAssetReference: {fileID: 10304, guid: a2eb3ee376dd24a4f9221a30765d895b, type: 3}`
