How to run a setup method when a package is imported/updated?

Hi @caioteixeira5!

There are no existing callbacks to know when a package is installed/updated or removed

But you can effectively used a InitializeOnLoadMethod fct to know which packages are installed.
Btw, this fct will be called at each domain reload (install/update/remove of a package but also entering play-mode)

Here's a code snippet (works with Unity 2019.1.0b9) you may starts with:

Code (CSharp):

1.  
2. using System.Text;
3. using System.Threading;
4. using UnityEngine;
5. using UnityEditor;
6. using UnityEditor.PackageManager;
7.  
8. public static class InstalledPackages
9. {
10.     [InitializeOnLoadMethod]
11.     private static void InitializeOnLoad()
12.     {
13.         var listRequest = Client.List(true);
14.         while (!listRequest.IsCompleted)
15.             Thread.Sleep(100);
16.  
17.         if (listRequest.Error != null)
18.         {
19.             Debug.Log("Error: " + listRequest.Error.message);
20.             return;
21.         }
22.  
23.         var packages = listRequest.Result;
24.         var text = new StringBuilder("Packages:\n");
25.         foreach (var package in packages)
26.         {
27.             if (package.source == PackageSource.Registry)
28.                 text.AppendLine($"{package.name}: {package.version} [{package.resolvedPath}]");
29.         }
30.        
31.         Debug.Log(text.ToString());
32.     }
33. }
34.

Hi @caioteixeira5!

Sorry for this inconvenience.

I locally use Verdaccio and scoped registry in Packman and I was able to update my package published in my local registry.

The only difference I think, it's that my package contains scripts that I have updated.

Domain reload (which will call InitializeOnLoadMethod) will only occur if there are changes in scripts.

Does your package only contains assets (aka non scripts)?
Also, in Unity General preferences, do you have Auto-Refresh checked?

Hi @caioteixeira5!

I've updated the code snippet to take care of assets only change:

Code (CSharp):

1.  
2. using System.Linq;
3. using System.Text;
4. using System.Threading;
5. using UnityEngine;
6. using UnityEditor;
7. using UnityEditor.PackageManager;
8.  
9. public class InstalledPackages : AssetPostprocessor
10. {
11.     private static void OnPostprocessAllAssets(string[] importedAssets, string[] deletedAssets, string[] movedAssets, string[] movedFromAssetPaths)
12.     {
13.         var inPackages = importedAssets.Any(path => path.StartsWith("Packages/")) ||
14.             deletedAssets.Any(path => path.StartsWith("Packages/")) ||
15.             movedAssets.Any(path => path.StartsWith("Packages/")) ||
16.             movedFromAssetPaths.Any(path => path.StartsWith("Packages/"));
17.  
18.         if (inPackages)
19.         {
20.             InitializeOnLoad();
21.         }
22.     }
23.    
24.     [InitializeOnLoadMethod]
25.     private static void InitializeOnLoad()
26.     {
27.         var listRequest = Client.List(true);
28.         while (!listRequest.IsCompleted)
29.             Thread.Sleep(100);
30.  
31.         if (listRequest.Error != null)
32.         {
33.             Debug.Log("Error: " + listRequest.Error.message);
34.             return;
35.         }
36.  
37.         var packages = listRequest.Result;
38.         var text = new StringBuilder("Packages:\n");
39.         foreach (var package in packages)
40.         {
41.             if (package.source == PackageSource.Registry)
42.                 text.AppendLine($"{package.name}: {package.version} [{package.resolvedPath}]");
43.         }
44.        
45.         Debug.Log(text.ToString());
46.     }
47. }

You can adapt this code to only look in specific Packages.

 

You're welcome.
