Description

Each time an object of a specific type is indexed, the registered function is called.

[CustomObjectIndexer(typeof(Shader), version = 1)]
internal static void ShaderIndexing(CustomObjectIndexerTarget context, ObjectIndexer indexer)
{
    if (!(context.target is Shader shader) || !indexer.settings.options.properties)
        return;

    for (int i = 0, end = shader.GetPropertyCount(); i != end; ++i)
    {
        var name = shader.GetPropertyName(i).ToLowerInvariant();
        if (name.Length > 0 && name[0] == '_')
            name = name.Substring(1);
        switch (shader.GetPropertyType(i))
        {
            case UnityEngine.Rendering.ShaderPropertyType.Color:
                var v = shader.GetPropertyDefaultVectorValue(i);
                IndexColor(name, new Color(v.x, v.y, v.z, v.w), indexer, context.documentIndex);
                break;
            case UnityEngine.Rendering.ShaderPropertyType.Vector:
                v = shader.GetPropertyDefaultVectorValue(i);
                IndexVector(name, v, indexer, context.documentIndex);
                break;
            case UnityEngine.Rendering.ShaderPropertyType.Float:
                indexer.IndexNumber(context.documentIndex, name, shader.GetPropertyDefaultFloatValue(i));
                break;
        }
