Worth noting that the compilation time value is a cumulation of compilation performed on multiple threads, so it's not the time it took from start to finish.
@karljj1 I don't understand why you complicated all of your code ? would you mind explaining ?
This, OTOH, is simple and effective:
using System.Collections.Generic;
using System.Diagnostics;
using UnityEditor;
using UnityEditor.Compilation;
using Debug = UnityEngine.Debug;
[InitializeOnLoad]
internal static class CompilationTime
{
private static readonly Dictionary<string, Stopwatch> Dictionary;
private static readonly Stopwatch Stopwatch;
static CompilationTime()
{
CompilationPipeline.compilationStarted += OnCompilationStarted;
CompilationPipeline.compilationFinished += OnCompilationFinished;
CompilationPipeline.assemblyCompilationStarted += OnAssemblyCompilationStarted;
CompilationPipeline.assemblyCompilationFinished += OnAssemblyCompilationFinished;
Dictionary = new Dictionary<string, Stopwatch>();
Stopwatch = new Stopwatch();
}
private static void OnCompilationStarted(object context)
{
Dictionary.Clear();
Stopwatch.Start();
}
private static void OnCompilationFinished(object context)
{
var elapsed = Stopwatch.Elapsed;
Stopwatch.Stop();
Stopwatch.Reset();
foreach (var pair in Dictionary)
{
Debug.Log($"Assembly {pair.Key.Replace("Library/ScriptAssemblies/", string.Empty)} " +
$"built in {pair.Value.Elapsed.TotalSeconds:F} seconds.");
}
Debug.Log($"Total compilation time: {elapsed.TotalSeconds:F} seconds.");
}
private static void OnAssemblyCompilationStarted(string value)
{
Dictionary.Add(value, Stopwatch.StartNew());
}
private static void OnAssemblyCompilationFinished(string value, CompilerMessage[] messages)
{
Dictionary[value].Stop();
}
}
@aybe
I'm sure there are parts that can be made simpler however compilationStarted and compilationFinished did not exist when I wrote this(I actually requested them when I was writing it).
okay I understand now, thanks

#if UNITY_EDITOR
, I wanted to have this in my ThirdParty folder and Editor special folders don't work with .asmdef filesThanks for this, very useful! I found that I spent 1-2 seconds building test files and I very rarely run my tests, rather want to run those explicitly or as part of a build agent.
