Cache file generation

You can generate the prebuild content in another file. All regions are generate in the defined file with namespace and usings. It just require a namespace and a partial class.

Define the target file in a Prebuild Attribute.

using System;
using System.IO;
using UnityEngine;

namespace EODE.Wonderland._example {
    public class ExtExamplePack : PrebuildPackage {
        public Type[] Attributes {
            get {
                return new Type[] {
                    typeof(ExtExampleAttribute)
                };
            }
        }
    }

    public class ExtExamplePrebuildAttribute : PrebuildAttribute {
        public ExtExamplePrebuildAttribute() : base(typeof(ExtExamplePack)) {
            ExternalFilePath = Path.Combine(Application.dataPath, "Game", "ExtExampleCache.cs");
        }
    }
}

Example:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

namespace EODE.Wonderland._example {
    [ExtExamplePrebuild]
    public partial class MyExtExample {
        [ExtExample]
        void WorldTest() { }
    }
}

Generated script Assets/Game/ExtExampleCache.cs with 2 examples:

#region EODE.Wonderland._example.MyExtExample
namespace EODE.Wonderland._example {
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
    public partial class MyExtExample {
private void HelloExtWorldTest() {
    Debug.Log("Hello Prebuild");
    Debug.Log("test");
}
}}
#endregion
#region EODE.Wonderland._example.MyExtExample2
namespace EODE.Wonderland._example {
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
    public partial class MyExtExample2 {
private void HelloExtWorldTest() {
    Debug.Log("Hello Prebuild");
    Debug.Log("test");
}
}}
#endregion
