plooc's Issues
compile cpp source code(__OOC_CPP__ is defined) failed on arm-none-eabi-g++ 2021.10
can be fixed with modification in plooc.h below:
from
#if (!defined(__STDC_VERSION__) || __STDC_VERSION__ < 199901L) && !defined(__cplusplus)
#define __IMPLEMENT_EX(__TYPE, __NAME) \
__TYPE __NAME;
#else
#define __IMPLEMENT_EX(__TYPE, __NAME) \
union { \
__TYPE __NAME; \
__TYPE; \
};
#endifto
#if !defined(__STDC_VERSION__) || __STDC_VERSION__ < 199901L
#define __IMPLEMENT_EX(__TYPE, __NAME) \
__TYPE __NAME;
#else
#define __IMPLEMENT_EX(__TYPE, __NAME) \
union { \
__TYPE __NAME; \
__TYPE; \
};
#endifComparison with other solutions?
end_def_class 必须写 ？
# define __end_def_class(...)
好像宏里面也没有定义什么东西
union类型在这里起到了什么样的作用？
IMPLEMENT(INTERFACE)展开后得到
union {
INTERFACE use_as__INTERFACE;
INTERFACE;
};
下面那行的INTERFACE有什么意义吗？

#endifclass_internal / protected_internal 后面跟参数的意义？
# undef __with_class
# define __with_class(__TYPE, __SRC, ...) \
{ \
class(__TYPE)*_ =(class(__TYPE) *)(__SRC); \
PLOOC_UNUSED_PARAM(_); \
__VA_ARGS__; \
} \
for (class(__TYPE)*_ =(class(__TYPE) *)(__SRC);NULL != _; _ = NULL)
# undef with_class
# define with_class(__TYPE, __SRC, ...) \
__with_class(__TYPE, __SRC, __VA_ARGS__)
# undef __class_internal
# define __class_internal(__SRC, __DES, __TYPE, ...) \
class(__TYPE) *(__DES) = (class(__TYPE) *)(__SRC); \
PLOOC_UNUSED_PARAM(__DES); \
__with_class(__TYPE, (__SRC), __VA_ARGS__)
# undef class_internal
# define class_internal(__SRC, __DES, __TYPE,...) \
__class_internal(__SRC, __DES, __TYPE, __VA_ARGS__)
没有明白 __with_class 这个宏存在的意义是什么， VA_ARGS 需要这个参数是为了什么操作？
declare_class 在头文件中使用的必要性是什么？
我通过宏展开看到def_class 同样会有类的声明 ，即使不是用declare_class 貌似也不会有什么问题。 我的理解是否对？

How to compile the examples?
I tried to compile byte_queue.c. I copied all the plooc*.h files into example/byte_queue. I compiled it with this simple command:
gcc byte_queue.c -o byte_queue
But it always failed with this error:
C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/12.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/12.2.0/../../../../lib/libmingw32.a(lib64_libmingw32_a-crtexewin.o): in function `main':
C:/M/mingw-w64-crt-git/src/mingw-w64/mingw-w64-crt/crt/crtexewin.c:70: undefined reference to `WinMain'
collect2.exe: error: ld returned 1 exit status
As you can see, I'm on MSYS2 MINGW64. I have no idea why it failed to link the program.
Update: byte_queue.c doesn't have main function, so it's not a program (maybe a library?).
IMPLEMENT 和 INHERIT 的区别是？
/*! \note You can only use IMPLEMENT when defining INTERFACE. For Implement
* interface when defining class, you should use DEF_CLASS_IMPLEMENT
* instead.
*/
#define __IMPLEMENT(__INTERFACE) __IMPLEMENT_EX( __INTERFACE, \
use_as__##__INTERFACE)
#define IMPLEMENT(__INTERFACE) __IMPLEMENT(__INTERFACE)
/*! \note if you have used INHERIT or IMPLEMENT to define a class / INTERFACE,
you can use OBJ_CONVERT_AS to extract the reference to the inherited
object.
\*/
看注释 IMPLEMENT 是 INTERFACE 用的 ，但是我看代码中貌似INHERIT 用在 INTERFACE ， IMPLEMENT 用在CLASS 的继承。 是我理解错误了？
缺少使用的example
看了example1-3，限于自身水平看了很久，幸亏有参考 帮助。
然后看main.c后，我没get到PLOOC的优势。换句话说main.c很劝退，因为使用并没有多方便，相反做完了复杂的define init、define cfg、 define interface，然后main.c在调用的时候，并不会有多方便简洁，并没有看到什么优势。
可能是我水平太低了吧，或者我找错了库，我希望有个简单的OOC，让我方便继承，方便调用member function，如果方便到不用传this指针就更好了。
