Optimized JSON in C
Optimized JSON in C (OjC), as the name implies, was written to provide optimized JSON handling. It is derived from the underlying C parser in Oj and more recently OjG. The intended use is for applications that need the maximum performance when reading large JSON document from a file or socket.
Besides being a true streaming parser OjC produces a structure that handles all JSON constructs. It does not use a Hash or Map to represent the JSON object type but keeps all occurances of a pairs in the object element.
Multiple JSON elements are allowed in a single stream or from a socket. A callback mechanism is provided to return full JSON elements for each entry in a JSON stream.
#include <stdio.h>
#include "oj/oj.h"
int
main(int argc, char **argv) {
const char *str ="{\"num\": 12.34e567}"
struct _ojErr err = OJ_ERR_INIT;
ojVal val;
if (NULL == (val = oj_parse_str(&err, str, NULL))) {
printf("Parse error: %s at %d:%d\n", err.msg, err.line, err.col);
} else {
oj_destroy(val);
}
oj_cleanup();
return err.code;
}More example can be be found in the examples directory.
A comparison of OjC and simdjson is in the compare directory with results in the results.md file. For a more entertaining comparison take a look at OjC and Simdjson racing.
