Question

首先：我之前从未与Smalltalk合作过，所以这对我来说有点文化冲击。我使用的是Squeak 5.1（32位）。

现在我的问题：我想从GitHub存储库安装Smalltalk项目。我使用此代码成功安装了Metacello，在Transcript中执行它：

"Get the Metacello configuration (for Squeak users)"
Installer gemsource
    project: 'metacello';
    addPackage: 'ConfigurationOfMetacello';
    install.

"Bootstrap Metacello Preview, using mcz files (#'previewBootstrap' symbolic version"
((Smalltalk at: #ConfigurationOfMetacello) project 
  version: #'previewBootstrap') load.

"Load the Preview version of Metacello from GitHub"
(Smalltalk at: #Metacello) new
  configuration: 'MetacelloPreview';
  version: #stable;
  repository: 'github://dalehenrich/metacello-work:configuration';
  load.

"Now load latest version of Metacello"
(Smalltalk at: #Metacello) new
  baseline: 'Metacello';
  repository: 'github://dalehenrich/metacello-work:master/repository';
  get.
(Smalltalk at: #Metacello) new
  baseline: 'Metacello';
  repository: 'github://dalehenrich/metacello-work:master/repository';
  load.

我还使用以下代码安装了Metacello Scripting API：

Installer gemsource
    project: 'metacello';
    install: 'ConfigurationOfMetacello'.

如果我现在想要从GitHub存储库安装项目，例如：

Metacello new
  baseline: 'Animations';
  repository: 'github://hpi-swa/animations/repository';
  load.

然后我总是得到这个错误：

gofer repository error: 'GoferRepositoryError: UndefinedObject>>thisOSProcess'...ignoring

我错过了什么吗？

Answer 1

你是绝对正确的，那是行不通的。 OSProcess尚未被标记为与Squeak 5.1兼容，即使它是，它也没有被Metacello吸引。我会向开发者报告此事。

同时您可以使用

加载OSProcess

public ReadFromDB()
{
    var client = new MongoClient("mongodb://localhost:27017");

    var database = client.GetDatabase("test");
    var collectionWatchtbl = database.GetCollection<BsonDocument>("UserWatchtbl");

    var filter = new BsonDocument();
    var user = new List<UserWatchTblCls>();
    var cursor = collectionWatchtbl.FindAsync(filter).Result;
    cursor.ForEachAsync(batch =>
    {
        user.Add(BsonSerializer.Deserialize<UserWatchTblCls>(batch));
    });
}

public class UserWatchTblCls
{
    [BsonId]
    [BsonElement("_id")]
    public ObjectId Id { get; set; }
    public string fbId { get; set; }
    public string Name { get; set; }
    [BsonElement("pass")]
    public string Pass { get; set; }
    [BsonElement("Watchtbl")]
    public List<WatchTblCls> WatchTbls { get; set; }
}

public class WatchTblCls
{
    [BsonElement("wid")]
    public string WID { get; set; }
    [BsonElement("name")]
    public string Name { get; set; }
    [BsonElement("Symboles")]
    public List<SymboleCls> Symbols { get; set; }
}

public class SymboleCls
{
    public string Name { get; set; }
}
