/**********************************************************************************************
raylib API parser
This parser scans raylib.h to get API information about defines, structs, aliases, enums, callbacks and functions.
All data is divided into pieces, usually as strings. The following types are used for data:
- struct DefineInfo
- struct StructInfo
- struct AliasInfo
- struct EnumInfo
- struct FunctionInfo
CONSTRAINTS:
This parser is specifically designed to work with raylib.h, so, it has some constraints:
- Functions are expected as a single line with the following structure:
<retType> <name>(<paramType[0]> <paramName[0]>, <paramType[1]> <paramName[1]>); <desc>
Be careful with functions broken into several lines, it breaks the process!
- Structures are expected as several lines with the following form:
<desc>
typedef struct <name> {
<fieldType[0]> <fieldName[0]>; <fieldDesc[0]>
<fieldType[1]> <fieldName[1]>; <fieldDesc[1]>
<fieldType[2]> <fieldName[2]>; <fieldDesc[2]>
} <name>;
- Enums are expected as several lines with the following form:
<desc>
typedef enum {
<valueName[0]> = <valueInteger[0]>, <valueDesc[0]>
<valueName[1]>,
<valueName[2]>, <valueDesc[2]>
<valueName[3]> <valueDesc[3]>
} <name>;
NOTE: Multiple options are supported for enums:
- If value is not provided, (<valueInteger[i -1]> + 1) is assigned
- Value description can be provided or not
OTHER NOTES:
- This parser could work with other C header files if mentioned constraints are followed.
- This parser does not require <string.h> library, all data is parsed directly from char buffers.
