This is a tool to transpile a C header file (with includes) to a corresponding Oberon definition module.

It already works well with the SDL2 headers (with only minimal modifications), but consider the tool work-in-progress.

Note that since it is undecidable, whether a C pointer is indeed a pointer to the given object or in fact a pointer to an array of such objects, and Oberon only supports pointers to structured types, all *basic_type are converted to CPOINTER TO CARRAY of basic_type (i.e. *[]), but *structured_type are translated to Oberon CPOINTER TO structured_type (i.e. *). The special case of **type which is used to get a pointer out of a procedure is handled by *[]*type for structured types and void, and *[] for basic types.

Pending:

• process comments (line and block)
• consider #DEFINE constants
• use original type names for basic types (instead of plain C basic types)
