cppast - examples

This directory contains example tools written using cppast.

Note: These are not meant to be production ready tools, just a proof of concept!

All example executables get a single parameter, which is the directory where a compile_commands.json file is located. This file is a compilation database, you can read more about it here. CMake, for example, can generate on when the option CMAKE_EXPORT_COMPILE_COMMANDS is ON.

The tools will parse each file in the database and process it. Output will be written to stdout.

List of examples:

ast_printer.cpp

It is a very simplified implementation of the cppast tool, it will print an AST. This is the starting example, it showcases entity visitation.

documentation_generator.cpp

It is a very simplified documentation generator. This showcases usage of the cppast::code_generator.

Attributes example

• comparison.cpp
• documentation_generator.cpp
• enum_category.cpp
• enum_to_string.cpp
• serialization.cpp

Those examples were created as a part of my talk Fun With (User-Defined) Attributes. Check the talk video to learn more about them.
