INRIA/spoon
Jan 2015 - Apr 2015
Spoon is a metaprogramming library to analyze and transform Java source code. :spoon: is made with :heart:, :beers: and :sparkles:. It parses source files to build a well-designed AST with powerful analysis and transformation API.

Back-end Developer & Test Automation EngineerContributions:1 review, 8 commits, 4 PRs in 2 months
Contributions summary:Matias focused on enhancing the `spoon` library's functionality, particularly around the handling of signatures for different code elements. Their work involved modifying core components like `CtVisitor`, `SignaturePrinter`, and `CtElementImpl` to correctly generate signatures for various language constructs, including literals, method invocations, and variable references. They also implemented and refined test cases to ensure the signature generation and comparison mechanisms worked correctly, and contributed to bug fixes for serialization processes.
