A) make what claim, specifically? That my project met its goals? I stand by that.

B) I never said it was better than simdjson. I said it was competitive. I stand by that. I did mention algorithimically better ways to process json, but i'm talking about designing better software generally there, not designing a better processor than simdjson, and I think it's clear from the context. But that's the only time i use the word "better" in my post.

C) I haven't said anything here that I haven't said to the simdjson contributors themselves, by way of an #issue, and pull request, and discussion.

D) I am only testing against the ondemand api

void getEpisodeData(ondemand::object& root) {
    auto seasons = root["seasons"].get_array();
    auto sit = seasons.begin();
    while(sit!=seasons.end()) {
        auto season = *sit;
        auto episodes = season["episodes"].get_array();
        auto eit = episodes.begin();
        while(eit!=episodes.end()) {
            auto episode = *eit;
            auto season_number = episode["season_number"].get_int64();
            auto episode_number = episode["episode_number"].get_int64();
            auto name = episode["name"];
            ++eit;
        }
        ++sit;
    }
}


void extractEpisodes(LexSource &fls)
{
    // we don't need nearly this much. see the profile info output
    StaticMemoryPool<256> pool;
    JsonElement seasonNumber;
    JsonElement episodeNumber;
    JsonElement name;
    const char *fields[] = {"season_number", "episode_number", "name"};
    JsonExtractor children[] = {JsonExtractor(&seasonNumber), JsonExtractor(&episodeNumber), JsonExtractor(&name)};
    JsonExtractor extraction(fields, 3, children);
    JsonReader jr(fls);
    unsigned long long maxUsedPool = 0;
    int episodes = 0;
    while (jr.skipToFieldValue("episodes", JsonReader::Forward)) {
        if (!jr.read())
            break;
        while (!jr.hasError() && JsonReader::EndArray != jr.nodeType()) {
            // we keep track of the max pool we use
            if (pool.used() > maxUsedPool)
                maxUsedPool = pool.used();
            // we don't need to keep the pool data between calls here
            pool.freeAll();

            ++episodes;
            if (!jr.extract(pool, extraction)) {
                printf("\t\t%d. (extraction failed!)\r\n",episodes);
                break;
            }
        }
    }
    if (jr.hasError())
    {
        // report the error
        printf("\tError (%d): %s\r\n",(int)jr.error(),jr.value());
        return;
    }
}


The reason mine is competitive is simple. As you say it does not validate, or rather, it can, but the way I'm using it, it is not. But also it uses a lot less instructions per operation, generally, and examines each character less times than simdjson (usually). Currently my code is harder to use, but that will change once I finish building JSONPath on top of my query system.
