I'd like to run and editor script as soon as Unity launches. The closest I've been able to come is by using a CustomEditor on type Object, which launches as soon as something is selected.

Is it possible to run an editor script function when the Unity editor launches?

This could help

edit:
new link: Can I auto run a script when editor launches or a project finishes loading? - Questions & Answers - Unity Discussions

using UnityEngine;
using UnityEditor;
 
[InitializeOnLoad]
public class Autorun
{
    static Autorun()
    {
        Debug.Log("Autorun!");
    }
}

or if u want for the scene to be loaded, hook to the editor update callback

using UnityEngine;
using UnityEditor;
 
[InitializeOnLoad]
public class Autorun
{
    static Autorun()
    {
        EditorApplication.update += RunOnce;
    }
 
    static void RunOnce()
    {
        Debug.Log("RunOnce!");
        EditorApplication.update -= RunOnce;
    }
}

You could try a couple of different methods with OnEnable() (for example, on a class derived from "Editor", or on a custom editor window, or something like that). The only other way I could think of is to have a script with `Start()` or `Awake()` and have it set to `ExecuteInEditMode`, though I'm not sure if that would work.

I have taken the excellent code from the answer pointed to by vitamine and added it to the Community Wiki at unifycommunity.com .

Cheers!
