Only parses typedef struct { ... } type_name;
Will generate colliding definitions in case of types with the same name
Parsing expects more or less correct code, if you forget a semi it will generating bad code

Quick start

Create main.c

typedef struct { 
    int int_field;
    const char *const_char_star_field;
} My_Struct;

int main(void) {
    return 0;
}

Create cmeta.c

You only have to call process_file with a file to generate type infos etc in cmeta.h.

#define CMETA_COMPTIME
#include "cmeta.h"

int main(void) {
    if (!process_file("./main.c")) return 1;
    return 0;
}

Build and run cmeta

$ gcc cmeta.c -o cmeta
$ ./cmeta

Enjoy!

You can now inspect your types!

#include "cmeta.h"

typedef struct { 
    int int_field;
    const char* const_char_star_field;
} My_Struct;

int main(void) {
    printf("My_Struct.name = %s\n", my_struct_info.name);
    printf("My_Struct.fields_count = %zu\n", my_struct_info.fields_count);
    return 0;
}

$ gcc main.c -o main
$ ./main
My_Struct.name = My_Struct
My_Struct.fields_count = 2

[!INFO] It runs gcc -E, so it handles macros etc.
