Mingmoe.Demystifier 0.9.9

Utopia.Demystifier

Print your exceptions gracefully!

FEATURE:

• Use ZString
• Detailed frame stack information.
• Colored(and you can customize it) string.

Like:

Usage

// print to console(stdout)
exception.PrintColoredStringDemystified();

// or print it by yourself!
string msg = exception.ToColoredStringDemystified();

// OR
// save colored amd demystified string to exception
// NOTE:this may cause something not be colored.
exception.ColoredDemystify();

// you can customize your own style!
using Mingmoe.Demystifier;

StyledBuilderOption option = new StyledBuilderOption();
option.shortenSourceFilePath = false;
option.SourcePathStyle.BackgroundColor = Color.Red;
option.ParamNameStyle.ForeColor = new Color(128, 128, 128);
option.ParamTypeStyle.isBold = true;

// apply it
ex.PrintColoredStringDemystified(option);
ex.ToColoredStringDemystified(option);
ex.ColoredDemystify(option);

// or save it as an global and default option
// StyledBuilderOption.GlobalOption = option;
// ex.PrintColoredStringDemystified(); 
// ex.ToColoredStringDemystified()
// ex.ColoredDemystify();

Origin function from Ben.Demystifier should works.

Problems with current stack traces:

• constructors

  Does not match code, output as .ctor and .cctor

• parameters

  Do not specify qualifier ref, out or in

• iterators

  Cannot determine overload <Iterator>d__3.MoveNext() rather than Iterator(int startAt)+MoveNext()

• Linq

  Cannot determine overload

  Linq.Enumerable.SelectEnumerableIterator``2.MoveNext()

  rather than

  Linq.Enumerable+SelectEnumerableIterator<TSource, TResult>.MoveNext()

• async

  Cannot determine overload and no modifier such as async

  <MethodAsync>d__5``1.MoveNext()

  rather than

  async Task<string> Program.MethodAsync(int value)

  Noise!

• lambdas

  Mostly jibberish <>c__DisplayClass2_0.<.ctor>b__0(Object state) with a suggestion of where they are declared but no hint if there are multiple overloads of the method.

• local functions

  Mostly jibberish <RefMethod>g__LocalFuncParam|10_0(String val, <>c__DisplayClass10_0& ) with a suggestion of where they are declared but no hint if there are multiple overloads of the method.

• generic parameters

  Not resolved, only an indication of the number RunLambda(Func``1 lambda) rather than RunLambda(Func<string> lambda)

• value tuples

  Do not match code, output as ValueTuple``2 param rather than (string val, bool) param

• primitive types

  Do not match code, output as Int64, Boolean, String rather than long, bool, string

• return types

  Skipped entirely from method signature
