Build & Test

FastEnum.Extensions.Generator

Source Generator for enums to create extension methods with basic functionality.

Usage

Use the [Extensions] on your enums, so it will generate the extensions for those enums:

Feature

  • MembersCount (field)
  • GetValues
  • GetUnderlyingValues
  • GetNames
  • HasFlag
  • IsDefined
  • FastToString
  • FastToString with format option
  • GetDescription
  • TryParse (string/System.ReadOnlySpan<char>)
  • TryParseIgnoreCase (string/System.ReadOnlySpan<char>)

Note: I'm trying to make the generated code behave the same as the .NET implementation. If you find any differences, please let me know.

Limitations

  • Only currently supported .NET versions are supported. See: supported version list
  • .NET Framework is not supported
  • Generation extensions for enums nested in classes with generic type parameters are not supported.
  • Generation extensions for enums nested in multiple classes is not supported.

Example

using FastEnum;

namespace ToStringExample;

public class NestingClass
{
    [Extensions]
    public enum NestedInClassEnum
    {
        None
    }
}

[Extensions, Flags]
public enum Color
{
    [Description("Crimson Red")]
    Red = 0x990000,
    [Display(Name = "Pine", Description = "Pine")]
    Green = 0x166138,
    [EnumMember(Value = "Sky")]
    Blue = 0x87CEEB
}

[Extensions, Flags]
public enum GenerationOptions : byte
{
    None = 0,
    ToString = 1,
    Parse = 2,
    HasFlag = 4
}
There are no supported framework assets in this package.

- No source file is generated for empty enum's, an info analyzer warning is emitted instead.
- Analyzer warning placemnet changed, now the declaration line will be highlighted. (e.g.: "public enum Demo")
- Fixed an error when `System.ComponentModel.DataAnnotations.DisplayAttribute` is used with one named argument (i.e. either `Name` or  `Description`) the extension helper wasn't generated.
- Generated code is performance tested and any performance degradation is resolved compared to the .NET implementation.
- Internals updated for more efficient and faster code generation.
- Cosmetic changes in generated code.
- Some generated methods are inlined.
