Module

lexers.csharp_sm

Hand-written C# lexer using composable scanner mixins.

O(n) guaranteed, zero regex, thread-safe.

Language Support:

  • C# 12 syntax
  • Attributes (@Obsolete, [Attribute])
  • Verbatim identifiers (@class, @var)
  • Interpolated strings ($"..."), verbatim strings (@"...")
  • Raw string literals (triple-quoted) — C# 11
  • All numeric literal formats with_separators

Architecture:

Uses C-style mixins. C#-specific additions (from Java template):

  • @prefix: attribute → NAME_DECORATOR, verbatim identifier → NAME
  • $"..." and @"..."string prefixes
  • Triple-quote raw string literals

See Also:

  • rosettes.lexers.java_sm: Template for @ and raw string handling
