Cppinsights

cppinsights is a C++ compiler visualization and static analysis tool that uses the Clang frontend to parse source code into an abstract syntax tree. It functions as a source-to-source transformer, rewriting C++ code to make implicit compiler behaviors and hidden operations explicit and visible.

The tool specializes in unfolding complex language constructs, such as expanding the internal machinery of coroutines to visualize suspension and resumption logic. It also reveals the actual code generated during template instantiation and transforms implicit compiler actions, including structured bindings and special member functions, into explicit source representations.

Additional capabilities include the resolution of using statements and the generation of structural maps for C++ class inheritance hierarchies.

Features

  • C++ Source-to-Source Transformers - Rewrites original C++ code into an expanded version by replacing implicit compiler operations with explicit statements.
  • AST-to-Source Generators - Produces explicit source representations by traversing the Clang abstract syntax tree to reflect lowered language semantics.
  • Compiler Behavior Visualizers - Visualizes how a C++ compiler interprets source code by expanding implicit operations into explicit, readable code.
  • Coroutine Machinery Visualizations - Transforms implicit coroutine suspension and resumption machinery into explicit representations for better understanding.
  • C# Compilers - Transforms C++ source code into explicit representations to reveal hidden compiler operations.
  • C++ Source-to-Source Translators - Rewrites C++ code to make implicit compiler behaviors and hidden operations explicit and visible.
  • Compiler-Integrated AST Parsing - Uses the Clang compiler frontend to parse C++ source code into abstract syntax trees for deep structural inspection.
  • Compiler Behavior Visualizations - Translates hidden compiler behaviors like upcasts and generated functions into visible code representations.
  • Implicit Compiler Action Expansions - Reveals hidden compiler actions like special member functions and implicit conversions through explicit source transformations.
  • C/C++ Static Analysis Tools - Analyzes C++ source code to visualize class hierarchies and expand implicit language constructs.
  • Coroutine Operation Expansions - Transforms implicit coroutine machinery into explicit representations to show suspension and resumption handling.
  • Template Instantiation Debugging - Reveals the actual code generated during the C++ template instantiation process.
  • Compiler Internals Education - Facilitates studying the internal workings of C++ by showing exactly how the compiler transforms high-level syntax.
  • Inheritance Visualizers - Generates structural maps of inheritance to visualize the organization and relationships between classes.
  • Using Statement Resolutions - Expands using statements that bring functions or members from base classes into the current class scope.
  • Structured Binding Expansions - Converts structured binding declarations into equivalent explicit operations to reveal implicit decomposition.
  • Debugging And Tracing - Shows source code as the compiler sees it.

    JavaParser is a library that parses Java source code up to version 12 into an Abstract Syntax Tree (AST), enabling programmatic analysis, transformation, and generation of Java code. It serves as a parser, code analyzer, code generator, comment parser, and symbol resolver, providing a unified toolkit for working with Java source at the AST level. The library distinguishes itself through several integrated capabilities that go beyond basic parsing. It includes a symbol resolution engine that resolves type and symbol references across files for accurate semantic analysis, and an error-recovery
