3. Top Level Function (weewiki_server)

The top-level function for this is weewiki_server. Since this is a command line program, it takes in argc and argv as arguments.

weewiki server will run the server with all the default values. It will read the default a.db and weewiki.janet configuration file. This will be the only thing implemented for now.

Later, the hope is to be able to pass in a weewiki database and have everything be served via that file (including an embedded config file).

int weewiki_server(weewiki_d *ww, int argc, char *argv[]);

static int running = 1;

static void quit(int sig)
{
    running = 0;
    printf("Signal Interrupt\n");
}

int weewiki_server(weewiki_d *ww, int argc, char *argv[])
{
    wwserver_d wws;
    wws.ww = ww;
    weewiki_init(ww);
    weewiki_set(ww);
    weewiki_parse_set(ww, parse_org);
    weewiki_print_set(ww, printer);
    weewiki_ud_set(ww, NULL);
    weewiki_is_server_set(ww, 1);

    if (argc >= 3) {
        wwserver_init(&wws, atoi(argv[2]));
    } else {
        wwserver_init(&wws, 8080);
    }

    if (argc >= 2) {
        if (argv[1][0] == '-') {
            /* '-' effectively skips this argument */
            /* needed if one wants to set the port only */
            weewiki_open(ww, "a.db");
            wws.use_sqlar = 0;
        } else {
            weewiki_open(ww, argv[1]);
            wws.use_sqlar = 1;
        }
    } else {
        weewiki_open(ww, "a.db");
        wws.use_sqlar = 0;
    }

    if (wws.use_sqlar) {
        weewiki_janet_loadconfig_internal(wws.env, wws.ww);
    } else {
        weewiki_janet_loadconfig(wws.env);

    }

    wwserver_global_set(&wws);

    if (wws.server != NULL) {
        signal(SIGINT, quit);
        http_server_listen_poll(wws.server);
        while (running) {
            http_server_poll(wws.server);
            usleep(80);
        }
    }
    wwserver_clean(&wws);
    weewiki_close(ww);
    weewiki_clean(ww);
    return 1;
}
