# treereduce `treereduce` is a fast, parallel, syntax-aware test case reducer based on tree-sitter grammars. In other words, `treereduce` helps you shrink structured data (especially source code) while maintaining some property of interest, for example, that the program causes a compiler crash or outputs a certain message. See [the documentation](./doc) for more information. Documentation is also available [online](https://langston-barrett.github.io/treereduce/).
