This fork of spoon (Let's call it "Spork") is an attempt to address the shortcomings of Spoon's architecture such as inconsistent behaviour of various interfaces, and to provide a faster, more streamlined API. I aim to accomplish this using custom Tree-Sitter grammars for each java version, and also by converting the code to use Kotlin. While the external API will still be usable via Java, there will be a number of breaking changes.
These include:
- No more generic type parameters on typed elements
- Any methods that could return null will be explicity marked
- The AST structure will be replaced by a Tree-sitter based CST, and Spork's grammar will differ from Spoon's. - This will most certainly break any existing visitors.
- AST elements will be treated as value types, and will not be duplicated unnecessarily.
- The CST will be based on a Red-Green tree approach, as used in Microsoft's Rosetta API.
- The current Spoon semantic model is slow and expensive to query; caching is not performed. This will be updated to treat symbol references as elements outside the spoon model, and cache references through an LRU cache before returning to the user.
- Removing the CompilationUnit class.
- Spoon-control-flow will be moved into spoon-core directly, and the control flow graph will be built at the same time as the CST to immediately provide CFA capabilities. This behaviour can be toggled.
- Tests will still be written in Java to serve as a way to test Java-kotlin interoperability.
- A few other tweaks I haven't figured out yet.

Spoon is an open-source library to analyze, rewrite, transform, transpile Java source code. It parses source files to build a well-designed AST with powerful analysis and transformation API. It supports modern Java versions up to Java 20. Spoon is an official Inria open-source project, and member of the OW2 open-source consortium.
The latest official documentation is available at http://spoon.gforge.inria.fr/.

Java version: Spoon version 10 and up requires Java 11 or later. Spoon 9.1.0 is the final Spoon release compatible with Java 8, and we do not plan to backport any bug fixes or features to Spoon 9. Note that Spoon can of course still consume source code for older versions of Java, but it needs JDK 11+ to run.
Get latest stable version with Maven, see https://search.maven.org/artifact/fr.inria.gforge.spoon/spoon-core
And start using it:
CtClass l = Launcher.parseClass("class A { void m() { System.out.println(\"yeah\");} }");Documentation:

Create your first pull request to improve the documentation, see doc! Proceed with your first bug fix! The community is open-minded, respectful and patient. All external contributions are welcome.
R1) The Spoon metamodel is as close as possible to the language concepts.
R2) The Spoon model of a program is complete and sound.
R3) The text version of a Spoon model is well-formed and semantically equivalent to the original program.
R4) The analysis and transformation API is intuitive and regular.
R5) Transformation operators are designed to warn as fast as possible about invalid programs. This is done either with static type checking or with dynamic checks when the operators are used.
R6) When feasible, the text version of a Spoon model is close to the original one.
To compile Spoon, you need a Java Development Kit (JDK) and Maven:
git clone https://github.com/INRIA/spoon
cd spoon
mvn compile
To run the tests:
mvn test
