C# grammar for tree-sitter based upon the Roslyn grammar with changes in order to:
- Deal with differences between the parsing technologies
- Work around some bugs in that grammar
- Handle
#if,#else,#elif,#endifblocks - Support syntax highlighting/parsing of fragments
- Simplify the output tree
- Reduce parser state count and complexity
- Be in-line with tree-sitter's convention where applicable
Comprehensive supports C# 1 through 13.0 with the following exception:
-
async,varandawaitcannot be used as identifiers everywhere they are valid
- Official C# 6 Language Spec provides chapters that formally define the language grammar.
- Roslyn C# language grammar export
- SharpLab (web-based syntax tree playground based on Roslyn)
