In a few words, the Generator is a utility that parses a collection of header and typesystem files, generating other files (code, documentation, etc.) as result.
Creating new bindingsEach module of the generator system has an specific role.
- Provide enough data about the classes and functions.
- Generate valid code, with modifications from typesystems and injected codes.
- Modify the API to expose the objects in a way that fits you target language best.
- Insert customizations where handwritten code is needed.
The newly created binding will run on top of Boost.Python library which takes care of interfacing Python and the underlying C++ library.
Creating new bindings involves creating two pieces of "code": the typesystem and the inject code.
- typesystem
XML files that provides the developer with a tool to customize the way that the generators will see the classes and functions. For example, functions can be renamed, have its signature changed and many other actions.
- inject code
allows the developer to insert handwritten code where the generated code is not suitable or needs some customization.
