Install: brew install castxml

About:
CastXML is a command-line tool that generates XML output from C, C++, and Objective-C source code by leveraging the Clang compiler frontend. It provides a structured representation of the Abstract Syntax Tree (AST), enabling other tools to parse and analyze code structure without implementing a full compiler front-end. This makes it a foundational component for static analysis, code documentation, and interoperability tools.

Key Features:

Outputs XML representations of C/C++/Objective-C ASTs
Leverages the robust Clang compiler frontend for accurate parsing
Provides a stable API for tool developers to consume code structure
Supports cross-platform static compilation

Use Cases:

Generating code documentation from source ASTs
Building static analysis and linting tools
Creating bindings for other programming languages (e.g., Python, Fortran)

Alternatives:

libclang – Provides a C API for the Clang AST, but CastXML offers a simpler, XML-based output that is easier to consume for non-C++ tools.
c2xml – An older tool for C code, whereas CastXML supports modern C++ and Objective-C features via Clang.
