Is there a way to see the full toString() content of a variable, including newlines?

[electrotype]

When debugging and hoving over a variable, or watching the variable in the Variables/Watch panels, is there a way to see the full result of toString() including the newlines?

Environment

• Operating System: Linux
• JDK version: 1.8
• Visual Studio Code version: 1.63.2
• Java extension version: 1.2.0
• Java Debugger extension version: 0.37.0

Steps To Reproduce

1. Create an instance of a SomeClass class that has:

@Override
public String toString() {
    return "toto\ntiti";
}

2. Add a breakpoint on a line where you can hover the instance to inspect it.

Current Result

The popup debug window displays: SomeClass@123 "toto

Expected Result

The popup debug window displays:

SomeClass@123 
"toto
titi"

Additional Informations

This can especially useful when the toString() result is something like a JSON object that is human friendly formatted.

Ideally the full result would be in a zone where it could be easily copied!

Look likes the newline is escaped, need to take a look with the upstream VS Code together about how to support that.

This request is tracked here:

• View and copy toString() of objects in the VARIABLES and WATCH windows vscode-java-pack#1264

Workarounds & Settings

• Set the maximum string length to unlimited in your VS Code settings (User or Workspace settings.json):

  "java.debug.settings.maxStringLength": 0

  View and copy toString() of objects in the VARIABLES and WATCH windows vscode-java-pack#1264 (comment)

• In the VARIABLES or WATCH view, right-click the value and choose Copy Value. This pastes the full toString() output (including newlines).

• Use the Debug Console to evaluate the expression manually:

  myVar.toString()
  

  This will print the complete, multiline string.

Is there a status on this? I also would appreciate to be able to see e.g. json Strings in the mouseovers, not just the first line. By the way - in the mouseover of the variable contents visualized on the right on the current line this is possible. Would be really nice to have this possibility on the other mouseovers also.

Maybe this issue is out of scope because a developer named 'testforstephen' is assigned to it?
