Funcky 2.7.0 | Funcky.XUnit 1.0.0 | Funcky.Analyzers 1.1.0

This release is the last non-breaking release for Funcky before 3.0.

Deprecations

• EnumerableExtensions.CartesianProduct will be removed in Funcky 3.
• To align our naming with that of the BCL, the ParseOrNone methods
  that return a type that has a keyword in C# int, long, etc. use the name of the BCL type instead.
  Example: ParseIntOrNone becomes ParseInt32OrNone.
  The old methods will be removed in Funcky 3.
• In preparation for Funcky 3 we deprecated Option<T>.None when used as method group. Use Option.None<T> instead.

New ParseOrNone extensions

With the help of a source generator we have added a lot of new ParseOrNone methods for various types from the BCL:

• Unsigned integer types
• DateOnly, TimeOnly
• Version
• Support for ReadOnlySpan<T> as input
• ... and more

Convenience for Either and Result

• Added implicit conversions for Either and Result.
• Implement Inspect for Either and Result.
• Added Partition for IEnumerable<Either> and IEnumerable<Result>.
• Added ToString on Either and Result.
• Implement ToEither on Option.

IEnumerable<T> extensions

• AnyOrElse
• Prefix sum: InclusiveScan and ExclusiveScan

Analyzers

This release adds two new analyzer rules:

• λ1003: Warning when certain methods, such as Match are used without argument labels
• λ1004: Warning that suggests .ConcatToString() over .JoinToString("")

Both of these warnings come with corresponding code fixes.

Funcky.Xunit

• Breaking: Funcky.Xunit now uses the Funcky namespace, instead of Funcky.Xunit.
• Add assertion methods for testing Either: FunctionalAssert.IsLeft and FunctionalAssert.IsRight.
