Generates all files in src/wrapped/generated
===
TL;DR: Automagically creates type definitions (/.F.+/ functions/typedefs...).
All '//%' in the headers are used by the script.
Reads each lines of each "_private.h" headers.
For each of them:
- If if starts with a #ifdef, #else, #ifndef, #endif, it memorizes which definition is required
- If it starts with a "GO", it will do multiple things:
- It memorizes the type used by the function (second macro argument)
- It memorizes the type it is mapped to, if needed (eg, iFEvp is mapped to iFEp: the first "real" argument is dropped)
- It checks if the type given (both original and mapped to) are valid
- If the signature contains a 'E' but it is not a "GOM" command, it will throw an error
- If the line starts with a '//%S', it will memorize a structure declaration.
The structure of it is: "//%S <letter> <structure name> <signature equivalent>"
NOTE: Those structure letters are "fake types" that are accepted in the macros.
After sorting the data, it generates:
wrapper.c
---------
(Private) type definitions (/.F.+_t/)
Function definitions (/.F.+/ functions, that actually execute the function given as argument)
isSimpleWrapper definition
wrapper.h
---------
Generic "wrapper_t" type definition
Function declarations (/.F.+/ functions)
*types.h
--------
Local types definition, for the original signatures
The SUPER() macro definition, used to generate and initialize the `*_my_t` library structure
(TODO: also automate this declaration/definition? It would require more metadata,
and may break sometime in the future due to the system changing...)
*defs.h
-------
Local `#define`s, for signature mapping
*undefs.h
---------
Local `#undefine`s, for signature mapping
Example:
========
