Spirit Parser Library

Compare

  Analyzed about 15 hours ago

Sprache

Compare

  Analyzed about 11 hours ago

Sprache makes parsing 'external' DSLs clean and simple. It does this by relying on C# language features like lambda expressions and Linq. Unlike most parser-building frameworks, you use Sprache directly from your program code, and don't need to set up any build-time code generation tasks.
