Spoon is an open-source Java metaprogramming library that parses Java source code into a well-designed AST and provides powerful APIs for analysis, rewriting, transformation, and code generation. It is an official Inria project, supports Java up to version 25, and ships with Maven/Gradle plugins and a fluent testing API for transformations.

Use cases

  • analyze java source code with an ast
  • refactor java code programmatically
  • generate java source code from templates
  • write static analysis tools for java
  • apply semantic patches to java codebases
  • test java code transformations
  • transpile or rewrite java source files

When to choose

  • you need to parse, query, or transform Java source code at the AST level
  • you are building static analysis, refactoring, or code generation tools for Java
  • you want a mature, well-documented library with Maven/Gradle integration and transformation testing support

When to avoid

  • you need to analyze bytecode rather than source code
  • you work with languages other than Java
  • you only need simple linting that existing linters already cover
