Prelude

Tyne's common core types can be shortened using Tyne's prelude system, which is designed to make using common types more ergonomic.

Tyne's core prelude is enabled by default, but can be controlled with the TynePrelude property:

<PropertyGroup>
    <!-- Disables the Tyne prelude -->
    <TynePrelude>disable</TynePrelude>
    <!-- Enables the Tyne prelude (default setting) -->
    <TynePrelude>enable</TynePrelude>
</PropertyGroup>

Preludes come enabled by default. When enabled:

• Unit.Value is imported statically as unit:

  // Without prelude
  return Unit.Value;
  
  // With prelude
  return unit;
  

• Result creation methods are imported statically:

  // Without prelude
  var okResult = Result.Ok<int, string>(42);
  var errorResult = Result.Error<int, string>("some error");
  
  // With prelude
  var okResult = Ok<int, string>(42);
  var errorResult = Error<int, string>("No value");
  

• Option creation methods are imported statically:

  // Without prelude
  var some = Option.Some(101);
  var none = Option.None<int>();
  
  // With prelude
  var some = Some(101);
  var none = None<int>();
