StackCleaner

Download the latest version on NuGet (Releases will no longer be kept up to date) https://www.nuget.org/packages/DanielWillett.StackCleaner

Clears up stack traces to make them much more readable during debugging.

Supports highly customizable color formatting in the following formats:

• ConsoleColor
  • Only supported with the WriteToConsole method as it directly sets Console.ForegroundColor.
• ANSI color codes (3-bit or 4-bit)
• Extended ANSI color codes (32-bit where supported)
• Unity Rich Text
• Unity TextMeshPro Rich Text
• Html (with tags)

Example (Extended ANSI)

Usage

using StackCleaner;
using Color = System.Drawing.Color; // only needed when dealing with Color32Config.

Get StackTrace from Exception

StackTrace stackTrace = StackTraceCleaner.GetStackTrace(exception);

All the following methods also have an overload to print an exception's stack trace and any existing remote stack traces on Mono. Remote stack traces are mainly caused by a context switch in async functions.

Write To Console

StackTraceCleaner cleaner = new StackTraceCleaner(new StackCleanerConfiguration
{
  ColorFormatting = StackColorFormatType.ExtendedANSIColor,
  IncludeFileData = true,
  IncludeILOffset = true,
  IncludeNamespaces = false,
  Colors = Color32Config.Default
});

// assume Exception ex was caught

Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine(ex.GetType().Name + " - " + ex.Message);

cleaner.WriteToConsole(ex);

Write To String

StackTraceCleaner cleaner = new StackTraceCleaner(new StackCleanerConfiguration
{
  ColorFormatting = StackColorFormatType.None,
  IncludeNamespaces = false
});

StackTrace stackTrace = /* etc */;
UnityEngine.UI.TextBox textBox = /* etc */;
textBox.text = cleaner.GetString(stackTrace);

Write To File

StackTraceCleaner cleaner = new StackTraceCleaner(new StackCleanerConfiguration
{
  ColorFormatting = StackColorFormatType.Html,
  IncludeNamespaces = false,
  IncludeSourceData = false,
  HtmlUseClassNames = true
});

StackTrace stackTrace = /* etc */;
string str = cleaner.WriteToFile(@"C:\error.html", stackTrace, System.Text.Encoding.UTF8);

Write To Stream

StackTraceCleaner cleaner = new StackTraceCleaner(new StackCleanerConfiguration
{
  ColorFormatting = StackColorFormatType.Html,
  IncludeNamespaces = false,
  IncludeSourceData = false,
  HtmlUseClassNames = true
});

StackTrace stackTrace = /* etc */;
NetworkStream stream = /* etc */;

// async variant also available
cleaner.WriteToStream(stream, stackTrace, System.Text.Encoding.UTF8);

Write To TextWriter

StackTraceCleaner cleaner = new StackTraceCleaner(new StackCleanerConfiguration
{
  ColorFormatting = StackColorFormatType.UnityRichText,
  IncludeNamespaces = true,
  IncludeSourceData = false,
  HiddenTypes = new Type[]
  {
      typeof(ExecutionContext),
      typeof(TaskAwaiter),
      typeof(TaskAwaiter<>),
      typeof(ConfiguredTaskAwaitable.ConfiguredTaskAwaiter),
      typeof(ConfiguredTaskAwaitable<>.ConfiguredTaskAwaiter),
      typeof(System.Runtime.ExceptionServices.ExceptionDispatchInfo),
      typeof(UnityEngine.Debug),
      typeof(UnityEngine.Assert),
      typeof(UnityEngine.PlayerLoop)
  }
});

StackTrace stackTrace = /* etc */;
Stream stream = /* etc */;

// async variant also available
using TextWriter writer = new TextWriter(stream, System.Text.Encoding.UTF8);
cleaner.WriteToTextWriter(stackTrace, writer);

Configuration

Default

// Default values (see default configuration values below)
StackTraceCleaner.Default.WriteToConsole(stackTrace);

Custom

public static readonly StackTraceCleaner StackTraceCleaner = new StackTraceCleaner(new StackCleanerConfiguration
{

/* Format Configuration = default */

  // Determines how colors are added to formatting (if at all), see StackColorFormatType below.
    ColorFormatting = StackColorFormatType.None,

  // Only used for Source Data, determines what format provider is used to translate line numbers and IL offsets to strings.
    Locale = CultureInfo.InvariantCulture,

  // Source data includes line number, column number, IL offset, and file name when available.
    IncludeSourceData = true,

  // Appends a warning to the end of the stack trace that lines were removed for visibility.
    WarnForHiddenLines = false,

  // Source data is put on the line after the stack frame declaration.
    PutSourceDataOnNewLine = true,

  // Namespaces are included in the method declaration.
    IncludeNamespaces = true,

  // IL offsets are included in the source data.
    IncludeILOffset = false,

  // Line and column numbers are included in the source data.
    IncludeLineData = true,

  // Relative source file path will be included in the source data.
    IncludeFileData = false,

  // Assembly-qualified name (and path if IncludeFileData is true) will be included in the source data.
    IncludeAssemblyData = false,

  // 'Primitive' types will use their aliases. For example, 'int' instead of 'Int32'.
    UseTypeAliases = false,
    
  // If ColorFormatting is set to 'Html', use css class names (defined as public constants in the StackTraceCleaner class) instead of style tags.
    HtmlUseClassNames = false,

  // If ColorFormatting is set to 'Html', write an outer <div> with a background color around the output HTML.
    HtmlWriteOuterDiv = false,

  // Types who's methods will be skipped in stack traces.
    HiddenTypes = /* See Below */,

/* Color Configuration */

  // As close as possible to the default Visual Studio C# formatting rules in 4 bit color (System.ConsoleColor)
  // Default value of Colors
    Colors = Color4Config.Default. 
    
  // The default Visual Studio C# formatting rules
    Colors = Color32Config.Default,

  // Color settings with 4 bit colors, best for Color formatting of ANSIColor or ConsoleColor (or None).
    Colors = new Color4Config
    {
      KeywordColor = ConsoleColor.Green
    },

  // Color settings with 32 bit colors, best for Color formatting of everything else (or None).
    Colors = new Color32Config
    {                            // alpha channel is ignored
      KeywordColor = Color.FromArgb(255, 230, 255, 153)
    },

  // Color settings with 32 bit colors when using UnityEngine (because System.Drawing is not available).
  // This is only available in the .NET Framework 4.6.1 or 4.8.1 and .NET Standard 2.1 builds.
    Colors = new UnityColor32Config
    {                                            // alpha channel is ignored
      KeywordColor = new Color(0.34f, 0.61f, 0.84f, 1f)
    }
});

Colors

enum StackColorFormatType

• None => No color formatting, just raw text.
• ConsoleColor => Sets the Console.ForegroundColor for each section. Only applicable when printed to console with WriteToConsole
• UnityRichText => UnityEngine rich text tags. See more: Unity Rich Text
• TextMeshProRichText => TextMeshPro rich text tags. See more: Unity Rich Text
• ANSIColor => ANSI Terminal text formatting codes. See more: Microsft: Virtual Terminal Text Formatting.
• ExtendedANSIColor => ANSI Terminal text formatting codes. See more: Microsft: Virtual Terminal Extended Color Formatting.
• Html => Text is colored with <span> tags. Use classes instead of constant CSS styles by setting HtmlUseClassNames to true. The classes are public constants in StackTraceCleaner.
• ANSIColorNoBright => ANSI Terminal text formatting codes without the bright bit. Discord can display this in an ansi code block.

Custom Color Provider

A UnityColor32Config is already included, but this shows one way you could create a custom color provider. The base properties are stored in Int32 values formatted in ARGB32 converted like shown below:

unchecked
{
    int argb = color.a << 24 | color.r << 16 | color.g << 8 | color.b;

    byte a = (byte)(argb >> 24), r = (byte)(argb >> 16), g = (byte)(argb >> 8), b = (byte)argb;
}

Please note that you can use StackCleaner without referencing UnityEngine.dll as long as you don't access the UnityColor32Config class.

UnityEngine.Color Custom Converter:

using StackCleaner;
using UnityEngine;
using Color = UnityEngine.Color;

internal sealed class UnityColorConfig : ColorConfig
