小编Jon*_*ono的帖子

我有一个控制器,我试图从远程源获取XML文件.

就像是:

@artist = Nokogiri.XML(open(url).read)

但是,我希望一次执行多个这些不同的数据.我可以用某种方式使用线程吗？

单独执行一个需要400毫秒.因此,当它们连续三次执行时,响应最多可达1s +.

我正在制作iPad应用程序(iOS7,XCode5).

我正在播放包含视频和音频的HLS流(m3u8).当设备进入后台时,它将停止播放.有没有办法从视频中分离音频,只是在后台播放视频？看来Apple似乎不希望你在后台播放视频.

有任何想法吗？谢谢.

我似乎无法让这个工作.wordexp()当我称之为:

wordexp("beep", &p, 0);
w = p.we_wordv;
argc = p.we_wordc;

不过,我想在一些值,用户将进入通过,然后得到argv和argc从.现在我有以下代码,但我总是收到"分段错误"或"EXC_BAD_ACCESS":

char **parseCommand(char *args, int *argc) {
    printf("args %s\n", args);
    wordexp_t p;
    char **w;
    int i;
    char *beep;

    wordexp(args, &p, 0);

    w = p.we_wordv;
    argc = p.we_wordc;

    wordfree(&p);
    return w;
}

当我打印args时,它会显示它.我甚至试过strcpyargs到另一个字符串.但仍然得到错误.一定是傻事(或者用wordexp不能做到这一点)？

我正在尝试使用nowjs在nodejs应用程序上实现自动填充程序.

everyone.now.sendAutocomplete = function(search) {  
  var response = getAutocomplete(search);
  console.log("response");
  console.log(response);
};

哪个叫:

function getAutocomplete(search) {
    console.log(search);
    var artist = new Array();

    request({uri: 'http://musicbrainz.org/ws/2/artist/?query=' + search + '&limit=4', headers: "Musicbrainz Application Version 1"}, function(error, response, body) {
        par.parseString(body, function(err, result) {
            var count = result['artist-list']['@']['count'];

            var artists = result['artist-list']['artist'];
            // var artist = new Array();

            if (count > 1) {
            artists.forEach(function(a) {
                var att = a['@'];
                var id = att['id'];
                var name = a['name'];
                var dis = a['disambiguation'];

                if (dis) …

我希望当用户附加一个命令后,它将在后台执行.出于某种原因,如果我正常执行命令它将等待,然后如果我在后台执行命令它将工作,但如果我正常执行命令它将不会等待它.我确信我只是在做一些小错误的事情.有任何想法吗:

void executeSystemCommand(char *strippedCommand, char *background, int argc, char **args) {
    char pathToExecute[80];


    // Check if command will be executed in the background
    int shellArgs;
    bool bg; 
    if (!strcmp(background, "-")) {
        bg = true;
        shellArgs = argc -1; 
    } else {
        bg = false;
        shellArgs = argc;
    }   

    // Save the linux commands in a new array
    char *executableCommands[shellArgs+1];
    int j;
    for (j = 0; j < shellArgs+1; j++) {
        executableCommands[j] = args[j];
    }   
    executableCommands[shellArgs] = NULL;

    // Check the …

所以我试图使用github api并将其转换为用于dynatree.

我期待使用javascript.但如果在Ruby,ClojureScript等中更容易完成,那么也可以.

所以Github api返回的内容如下:
