Question

我是新的tcl用户。我正在尝试为输出文件键入空格。我正在使用lappend命令：

lappend lineM1 [ format "%-4s" "     " ]
set outfile [open "test" w]
    puts $outfile "$lineM1"
    close $outfile

这就是我得到的：

{     }

如何删除括号？如何仅打印空格？

Answer 1

我不确定你想做什么，但如果你更换了 lappend set lineM1 list。你没有得到括号。

tcl命令lappend是format "%-4s" " "命令。它会将lineM1的结果附加到尚未存在的列表$outfile。

顺便说一下，如果您只是想在format中打印空白区域，则不需要set foo "bar" puts $foo该空白区域。也许你应该看一下format manual page。

示例：

bar

将导致：

$outfile

在您的情况下，您会将文件句柄puts添加到puts $outfile $foo来电：

        String serviceAccountEmail = "3512650851-4tpr9073rju4deqtfjp210j07q52hu2j@developer.gserviceaccount.com";
        var certificate = new X509Certificate2(@"My Project-d3e5dda28438.p12", "notasecret", X509KeyStorageFlags.Exportable);

        ServiceAccountCredential credential = new ServiceAccountCredential(
        new ServiceAccountCredential.Initializer(serviceAccountEmail)
        {
            User = "<UserEmail for which to download message>",
            Scopes = new[] { GmailService.Scope.GmailCompose, GmailService.Scope.GmailModify }
        }.FromCertificate(certificate));


        var gmailservice = new Google.Apis.Gmail.v1.GmailService(new BaseClientService.Initializer()
        {

            HttpClientInitializer = credential,
            ApplicationName = "MyNewProject",
        });

        try
        {
            ListMessagesResponse messages = gmailservice.Users.Messages.List("<User Email>").Execute();
            IList<Google.Apis.Gmail.v1.Data.Thread> threads = gmailservice.Users.Threads.List("<User Email>").Execute().Threads;
            List<Message> responsemessages = new List<Message>();
            responsemessages.AddRange(messages.Messages);

            foreach(Message msg in responsemessages)
            {
                Google.Apis.Gmail.v1.UsersResource.MessagesResource.GetRequest gr = gmailservice.Users.Messages.Get("<User Email>", msg.Id);
                gr.Format = Google.Apis.Gmail.v1.UsersResource.MessagesResource.GetRequest.FormatEnum.Full;
                Message m = gr.Execute();

                if (gr.Format == Google.Apis.Gmail.v1.UsersResource.MessagesResource.GetRequest.FormatEnum.Raw)
                {
                    byte[] decodedByte = FromBase64ForUrlString(m.Raw);

                    string base64Encoded = Convert.ToString(decodedByte);
                    MailMessage msg2 = new MailMessage();

                    //msg2.LoadMessage(decodedByte);
                }
            }
        }
        catch (Exception ex) { }
