v3.0.0

Removed

• Removed support for .NET 4 and .NET Core 3.1. Pidgin is now a .NET 5 library.

Added

• Published the (previously internal) TokenStream API. You can now write parsers which consume custom input streams.
• Support for resumable parsing, through the ResumableTokenStream class.
• An experimental API for writing your own parsers by subclassing Parser.

Changed

• Parser.Real is now a property and not a method.
• A new design for computing source positions. posCalculator now returns a SourcePosDelta struct representing the amount of text covered by a token, rather than updating the current source position in place.
  • Performance improvements in the code which computes source positions.
• The Parse methods in ParseExtensions now take an IConfiguration object as an optional parameter (instead of a posCalculator func).
  • If you were using posCalculator, you can instead subclass DefaultConfiguration and override the PosCalculator property.
• Performance improvements across the board thanks to a new Span-based implementation.
• Performance improvements in SkipWhitespaces.
• A new CI build system based on GitHub Actions.
