A C macros library to encode bson strings at compile time.
It can encode only simple values - bson documents with int32_t and int64_t. All keys must be known at compile time. Keys and values will appear in resulting bson in reversed order they were specified.
BSON_DOCUMENT is a variadic macro. It accepts number of keys in document and groups of arguments - type (INT32 or INT64), key string (can be both a variable and literal), key length without trailing zero (must be a literal) and value(can be both variable and literal).
#include <stdio.h>
#include <stdint.h>
#include "bson.h"
int main(){
int32_t val = 50;
uint8_t a[] = {BSON_DOCUMENT(2, INT32, val2, 4, val, INT64, val1, 4, 100)};
}Big part of bson.h was written from this stackoverflow answer and Cloak library by Paul Fultz II.
