Aliasing a supertype makes the aliased occurrence appear as a regular node in the syntax tree. For example, ``` alias($.expression, $.expression_target) ``` can produce: ``` (expression_target (identifier)) ``` Previously, node-types generation skipped the source supertype entirely. It could reference `expression_target` as a field or child type without emitting a corresponding top-level entry for it. Continue emitting the canonical `expression` entry with its `subtypes`, but pass aliased appearances through regular node generation so their children and fields are recorded and merged normally. |

tree-sitter
Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
