• Diagnostic

  • [MetadataScript]

    Auto generate code executed by Execute

    

  • [AutoMetadataFrom(Type, MemberTypes)] :

    Auto generate code using Template from target type members

    

  • [AutoTypeInference] :

    Auto generate Type detected from anonymousobject creation

    

  • [RecordIgnore] :

    Auto exclude member calculation in GetHashCode and PrintMembers of record

• [AutoStringTo(string, Accessibility)] :

  Auto generate string To extension

  only on assembly and static partial class

  

• Mapping :

  • [AutoMap(Accessibility)] :

    Auto generate mappings between types

    Only on partial method

    

    You can use to generate shallow copy

  • [MapBetween(fromProperty, toProperty)] :

  void Fun([CallerFilePath] string path = "")
  {
      var directory       = (FilePath)path << 1;
      var full            = directory / "Antelcat.AutoGen.Sample" / "Example.cs";
      var changeExtension = full - 2 + ".g.cs";
  }

  static partial class Extension;
  
  /// <generated>
  static partial class Extension
  {
