YEAST (YEAST Elaborates Abstract Syntax Trees) is a framework for
transforming tree-sitter parse trees before CodeQL extraction.
Core components:
- shared/yeast/ — Ast, Node, Schema, query matching engine, captures,
FreshScope, BuildCtx
- shared/yeast-macros/ — proc macros: query!, tree!, trees!, rule!
The query language is inspired by tree-sitter queries:
(assignment left: (_) @lhs right: (_) @rhs)
Templates support embedded Rust ({expr}), splicing ({..expr}),
computed literals (#{expr}), and fresh identifiers ($name).
The rule! macro combines query and transform:
rule!((for pattern: (_) @pat ...) => (call receiver: {val} ...))
