Hi,

Thank you for your great and useful json parser! It's super easy to use.

I've got an error when trying to parse a json object with an empty array. Example:

    json_t json2;
    char *test = "{\"foo\":\"bar\",\"boo\":[]}";
    json_load(&json2, test);

Error:

JSON ERROR: unknown token, expected value.
     1 | {"foo":"bar","boo":[]}
       |     

Kind regards,

Is there an easy way to merge two JSON objects? E.g. if they have the same keys then overwrite, otherwise add new?

Thanks,
Bartek

Hi,

Thanks for this great library! I noticed that non-scientific floating point numbers are not supported, i.e. they are parsed into completely wrong numbers which was hard to debug :)

E.g. this works: 1e-3 but this doesn't: 0.001, it actually outputs 0.1.

I propose to simplify json_expect_number to this code:

#include <stdlib.h>. // for strtod
...
static double json_expect_number(json_ctx_t *ctx) {
    // Convert string to double
    double num = strtod(&ctx->text[ctx->index], NULL);

    // Move pointer until not a comma and not end of line
    while (ctx->text[ctx->index] != ',' && ctx->text[ctx->index] != '\n' && ctx->text[ctx->index] != ']') {
        ctx->index++;
    }

    return num;
}

Works well this way with both scientific and regular notation.

Cheers,
Bartek
