Common debugger settings

Item

Description

Sort values alphabetically

Select this option to sort the values in the Variables pane of the Debug Tool Window.

Enable auto expressions in Variables view

Select this option if you want the IntelliJ IDEA debugger to automatically evaluate expressions and show the corresponding values in the Variables pane of the Debug Tool Window.

The debugger analyzes the context near the breakpoint (the current statement, one statement before, and one after). It does so to find various expressions in the source code (if available) such as, for example, myvar.myfield.

If such expressions don't contain explicit method invocations, the debugger evaluates them and shows the corresponding values in the Variables view.

Editor

Item

Description

Show values inline

Select this option to enable the Inline Values View feature that allows viewing the values of variables right next to their usage in the editor.

Show value tooltip

Select this option to display values of variables and expressions in an editor tooltip on mouse hover.

A tooltip in this context is a popup that provides an alternative, sometimes a more convenient presentation of values in the Variables pane of the Debug Tool Window.

To illustrate, let's assume that there is a statement like this in your code:


String s = "Hello, World!\nHello, World!";

When this statement is executed in the debugger, you'll see a line looking similar to this in the Variables pane:


s = {java.lang.String@62} "Hello, World!\nHello, World!"

with the line break shown as\n.

If the Show value tooltip option is on and you click this line and then hold the mouse pointer on it, you’ll see a yellow area (the "tooltip") in which the value of s is shown as

Hello, World!
Hello, World!

with a real line break in place of\n.

If this option is disabled, you can press Alt to display a value.

Value tooltips delay (ms)

Specify the delay (in milliseconds) between the moment when the mouse pointer hovers over an object in the Variables pane of the Debug Tool Window, and the moment when a tooltip with the object's value is displayed.

Show value tooltip on code selection

Select this option to enable tooltips that show the expression value when you select a code fragment in the editor. You can extend or shrink the selection with Ctrl+W/ Ctrl+Shift+W thus changing the evaluated expression:
