Class InputJSONNodeWriter

Serializes a InputJSONNode tree back to JSON text, matching the formatting Unity's own serializer produces for input action assets.

Inheritance

InputJSONNodeWriter
Inherited Members
Namespace: Scylla.Input
Assembly: ScyllaInput.dll
Syntax
public static class InputJSONNodeWriter
Remarks

Unity writes action assets with JsonUtility.ToJson(value, prettyPrint: true), which produces a four-space indent, a single space after each colon, LF newlines, inline [] for empty arrays, and no trailing newline. Reproducing that exactly is what lets a Scylla save of an unmodified asset leave version control untouched.

Two details are easy to get wrong. The Core writer's indent can only be changed through Scylla.Core.Util.Serialization.ScyllaJSONWriter.Configure(Scylla.Core.Util.Serialization.SerializationSettings); calling SetPrettyPrint(bool) alone leaves the default tab. And numbers are emitted through WriteRawValue(string) from their stored source text, because rendering a parsed value back would turn 1.0 into 1 and would depend on the current culture.

Fields

UNITY_INDENT

The indent Unity's pretty-printed JSON uses: four spaces per nesting level. The Core writer defaults to a tab, so this must be applied explicitly.

Declaration
public const string UNITY_INDENT = "    "
Field Value
Type Description
string

Methods

Write(InputJSONNode)

Serializes a tree using Unity's pretty-print formatting.

Declaration
public static string Write(InputJSONNode root)
Parameters
Type Name Description
InputJSONNode root

The root node.
Returns
Type Description
string

The JSON text, with no trailing newline.
Exceptions
Type Condition
ArgumentNullException

Thrown when the root is null.

Write(InputJSONNode, bool, string)

Serializes a tree with explicit formatting control.

Declaration
public static string Write(InputJSONNode root, bool prettyPrint, string indent)
Parameters
Type Name Description
InputJSONNode root

The root node.
bool prettyPrint

true to emit newlines and indentation, false for compact output.
string indent

The string repeated once per nesting level. Ignored when not pretty-printing.
Returns
Type Description
string

The JSON text, with no trailing newline.
Exceptions
Type Condition
ArgumentNullException

Thrown when the root is null.

WriteBytes(InputJSONNode)

Serializes a tree using Unity's formatting and returns UTF-8 bytes with no byte order mark.

Declaration
public static byte[] WriteBytes(InputJSONNode root)
Parameters
Type Name Description
InputJSONNode root

The root node.
Returns
Type Description
byte[]

The UTF-8 encoded JSON text.
Remarks

Prefer this over encoding the string yourself when writing to disk. Unity's action assets carry no byte order mark, and the framework's text-writing helper emits one by default, so going through bytes avoids a corrupt first line.

Exceptions
Type Condition
ArgumentNullException

Thrown when the root is null.
