Thanks for your feedback! In response, I've submitted Pull Request #1311 which removes the comment-continuation feature for ObjectScript comments (it's still enabled for class description /// comments). It also adds auto-closing of C-style block comments (e.g. typing /* automatically adds */ after the cursor). You can try this out by downloading and installing the latest beta version of the vscode-objectscript extension from GitHub, which can be found here.

If you upgrade to version 2023.3 or newer, you can use ##class(%RoutineMgr).OutOfDateDocuments() to check all documents in a namespace. You can use the various arguments to filter the documents that are checked (for example, to only check classes).

Hi @Mathew Rimmington, this exact question was asked in a GitHub discussion a few weeks ago. To summarize my answer there, this isn't easy to add because the text that gets added on enter (besides indentation) is static. It acn't be generated from the regular expression used to match the previous line, so I couldn't dynamically add the correct number of dots. My recommendation is to use modern brace syntax instead of legacy dot syntax.

ZWrite is going to output the internal format of the %Status value, which isn't that easy to parse visually. $SYSTEM.Status.DisplayError() will output the status text to the current device in a more readable format.

USER>Write ##class(%Atelier.v1.Utils.General).ValidateDocName("project.prj",.sc)
0
USER>ZWrite sc
sc="0 "_$lb($lb(16006,"project.prj",,,,,,,,$lb(,"USER",$lb("e^ValidateDocName+33^%apiSRC^2","e^ValidateDocName+1^%Atelier.v1.Utils.General.1^1","e^^^0"))))/* ERROR #16006: Document 'project.prj' name is invalid [ValidateDocName+33^%apiSRC:USER] */

USER>Do $SYSTEM.Status.DisplayError(sc)

ERROR #16006: Document 'project.prj' name is invalid [ValidateDocName+33^%apiSRC:USER]

If you need to store the status text in a variable you can use $SYSTEM.Status.GetErrorText().

The list of supported file systems for your version (2023.1) can be found here.

I recommend you use an intermediary stream to avoid <MAXSTRING> errors with large JSON objects:

ClassMethod DuplicateDAO(dao As %DynamicAbstractObject) As %DynamicAbstractObject
{
    Set strm = ##class(%Stream.TmpCharacter).%New()
    Do dao.%ToJSON(strm)
    Return ##class(%DynamicAbstractObject).%FromJSON(strm)
}

This is documented in the Server Manager's README. It will be added to the official InterSystems documentation for VS Code at a later date.

The VS Code Integrated Terminal is an OS shell, so if you want to open an IRIS terminal you need to use a command like "iris terminal <instance>". If that instance is on another machine, you'll have to use SSH. Starting with IRIS 2023.2, VS Code supports a WebSocket-based terminal so that you can launch a terminal on a remote server without needing SSH. The WebSocket terminal is not a full terminal though.

@Sam Duncan Here's a simple method to export subclasses. It exports all of the classes in a single XML file and prints that to the console. You can easily modify that behavior by changing the $SYSTEM.OBJ.Export() line to whatever export strategy you want.

ClassMethod ExportSubclasses(pSuper As %String) As %Status
{
  #Dim tSC As %Status = $$$OK
  #Dim tEx As %Exception.AbstractException
  #Dim tPc As %ProcedureContext
  #Dim tRs As %SQL.ClassQueryResultSet
  Try {
    #; Build a subscripted array of subclasses
    Set tStmt = ##class(%SQL.Statement).%New()
    Set tSC = tStmt.%PrepareClassQuery("%Dictionary.ClassDefinitionQuery","SubclassOf")
    If $$$ISERR(tSC) Quit
    Set tPc = tStmt.%Execute(pSuper)
    If tPc.%SQLCODE < 0 {
      Throw ##class(%Exception.SQL).CreateFromSQLCODE(tPc.%SQLCODE,tPc.%Message)
    }
    Set tRs = tPc.%NextResult()
    While tRs.%Next(.tSC) {
      Set tSubclasses(tRs.%GetData(1)_".CLS") = ""
    }
    If $$$ISOK(tSC), $DATA(tSubclasses) = 10 {
      #; Export the subclasses
      Set tSC = $SYSTEM.OBJ.Export(.tSubclasses,,"/nodisplay")
    }
  } Catch tEx {
    Set tSC = tEx.AsStatus()
  }
  Quit tSC
}
