Debugging code

Customize breakpoint settings

To customize breakpoint settings, press Ctrl+Shift+F8. To see all breakpoints in the project (with additional settings), click More or press the same shortcut Ctrl+Shift+F8 again.

Do not suspend code execution

Use action breakpoints to evaluate a variable at a particular line of code without suspending code execution. To create an action breakpoint, click the gutter while pressing Shift.

Create a temporary breakpoint

To create a breakpoint that stops only once, click the left gutter while holding Shift+Alt. For more information, refer to the section Breakpoints.

Disable breakpoints

To disable a breakpoint, click the breakpoint while pressing Alt.

Smart step into

Sometimes it happens that you stay at a line and want to step into a particular method but not the first one that will be invoked. In this case use Smart step into by pressing Shift+F7 to choose a particular method.

1. Place a breakpoint on the line that has a chain of calls or nested method calls.

2. Run a debugging session (Shift+F9).

3. Press Shift+F7.

4. From the context menu, select the method that you want to debug.

Run to cursor

1. Create a breakpoint.

2. Run a debugging session. To run a debugging session, click the Run Application icon () in the gutter area and select Debug <configuration_name>.

To stop code execution at the cursor position without adding another breakpoint, click the Run to cursor icon () or press Alt+F9. Alternatively, you can click the line number in the gutter area.

Evaluate expression

While in debug mode, you can evaluate any expression by pressing Alt+F8.

This tool provides code completion just as in the editor so it’s very easy to enter any expression:

If you have any instances marked with labels, code completion will offer you its names so you can evaluate them:
