Command Line Parameters to Open a File at Specified Line/Col

[AmyGilhespy]

Describe the solution you'd like
I want to be able to open a file from the command line and seek to a specified line and column. This is so I can open a specified file at a line/column position when clicking on a file or on an error message in Godot.

Describe alternatives you've considered
I currently use another editor.

Additional context
In Notepad++, for instance, I use this command:
C:/Program Files/Notepad++/notepad++.exe -lcs -n{line} -c{col} {file}

I would like something similar in RoslynPad.

in MainViewModelBase.cs,you can use nuget install commandlineparser ,recv args from commandline,and do something
eg:

private void OpenDocumentFromCommandLine()
{
    string[] args = Environment.GetCommandLineArgs();
    if (args.Length > 2)
    {
        OpenDocumentFromCommandLineEx(args);
    }
    else

    if (args.Length > 1)
    {
        string filePath = args[1];

        if (File.Exists(filePath))
        {
            var document = DocumentViewModel.FromPath(filePath);
            OpenDocument(document);
        }
    }

}

 void OpenDocumentFromCommandLineEx(string[] args)
 {
     if (args.Length < 3)
         return;

     //第一个参数必须是路径
     string filePath = args[1];

     if (File.Exists(filePath))
     {
         var document = DocumentViewModel.FromPath(filePath);
         //解析参数
         OpenDocument(document, args); // runAtNet462
     }
 }

 public void OpenDocument(DocumentViewModel document, string[] args)
 {
     OpenDocument(document); //调用原打开文档的方法
     var openDocument = CurrentOpenDocument!;
     Parser.Default.ParseArguments<ExecOptions>(args).WithParsed(op =>
     {
         ExecutionPlatform platform2 = openDocument.AvailablePlatforms.First();
         if (!string.IsNullOrEmpty(op.Platform))
         {
             Settings.DefaultPlatformName = openDocument.AvailablePlatforms.First(r => r.Description.Contains(op.Platform, StringComparison.OrdinalIgnoreCase)).Description;
         }
         Func<Task> task = async () =>
         {
             if (op.AutoRun)
             {
                 await openDocument!.Run(platform2!).ConfigureAwait(true);
                 //执行完才退出
                 if (op.AutoClose)
                 {
                     //程序退出
                     MainWindowClose?.Invoke();
                 }
             }
         };
         openDocument.AutoRun = () => task();
     });
 }

 class ExecOptions
 {
     [Option('p', "platform", Required = false, HelpText = "运行的目标框架")]
     public string? Platform { get; set; }

     [Option('r', "run", Required = false, HelpText = "是否在打开后立即自动执行")]
     public bool AutoRun { get; set; }

     [Option('c', "close", Required = false, HelpText = "是否在执行完成后自动关闭并退出")]
     public bool AutoClose { get; set; }
 }

scroll at DocumentView.cs, eg

public void SelectText(int start, int end)
{
    Editor.ScrollTo(start, end);
    Editor.SelectionLength = 1;
    Editor.Focus();

}
