我试图使用一个路径并用bash中的波形符替换主目录,我希望用必要的外部程序完成它.有没有办法只用bash来做到这一点.我有

${PWD/#$HOME/\~}

但那不太对劲.它需要转换:

/home/alice to ~
/home/alice/ to ~/
/home/alice/herp to ~/herp
/home/alicederp to /home/alicederp

作为一个感兴趣的注释,继承人在转换提示符中的\ w值时bash源如何做到这一点:

/* Return a pretty pathname.  If the first part of the pathname is
   the same as $HOME, then replace that with `~'.  */
char *
polite_directory_format (name)
     char *name;
{
  char *home;
  int l;

  home = get_string_value ("HOME");
  l = home ? strlen (home) : 0;
  if (l > 1 && strncmp (home, name, l) == 0 && (!name[l] …

自alpha 0.2以来,有没有人对此有任何更新？

我正在使用NH Criteria检索实体并将选择性字段投影到自定义类(有点像将数据投影到ViewModel上以便在MVC视图上显示).

使用ProjectionList很容易:

var emailCriteria = mSession.CreateCriteria<Email>();
emailCriteria.SetProjection(
    Projections.ProjectionList()
        .Add(Projections.Property("Subject"), "Subject")
);
emailCriteria.SetResultTransformer(Transformers.AliasToBean<EmailDataModel>());
var result = emailCriteria.List<EmailDataModel>();

但是,我的实体包含一个集合,我也希望将它带回来,并将其作为集合投影到我的自定义类中.

我的域模型看起来(简化形式)如下:

public class Email {
    public string Subject
    public List<EmailAttachment> Attachments
    etc...
}

public class EmailAttachment {
    public UploadedFile File
}

public class UploadedFile {
    public string Filename
    public UploadedFileData Data
}

public class UploadedFileData {
    public byte[] Data
}

这是我要投影到的"数据模型"类:

public class EmailDataModel {
    public string Subject
    public List<EmailAttachmentDataModel> Attachments
}

public class EmailAttachmentDataModel {
    public string Filename
    public byte[] Data …
