C# grammar for [tree-sitter](https://github.com/tree-sitter/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`, `#endif` blocks
|
|
- Support syntax highlighting/parsing of fragments
|
|
- Simplify the output tree
|
|
|
|
### Status
|
|
|
|
Comprehensive supports C# 1 through 11.0 with the following exceptions:

|
|
|
|
#### C# 12.0 (under development)
|
|
|
|
- [ ] Alias any type
|
|
- [ ] Collection expressions
|
|
- [ ] Default lambda parameters
|
|
- [x] Experimental attribute
|
|
- [ ] Inline arrays
|
|
