Debugger

Show debug window on breakpoint

If this checkbox is selected, CLion activates the Debug tool window on hitting a breakpoint.

Focus application on breakpoint

If this checkbox is selected, on hitting a breakpoint, CLion will show the location of this breakpoint in the editor and will attempt to bring its frame to the front.

Hide debug window on process termination

Automatically hide the Debug tool window when the debugged program terminates.

Scroll execution point to center

If this checkbox is selected, the line with the current execution point will be kept in the middle of the screen.

Click line number to perform run to cursor

If this checkbox is selected, you can click a line number in the editor to run program execution to this line.

Remove breakpoint

Select how you want to remove breakpoints:

• By clicking them with the left mouse button

• By dragging them to the editor or clicking them with the middle mouse button. In this case, clicking a breakpoint will toggle its state between enabled and disabled.

You can also choose whether you want a confirmation dialog to be displayed when you are about to remove a conditional or a logging breakpoint

Port

Use this spin box to specify the port on which the built-in web server runs. By default this port is set to 63342 through which CLion accepts connections from services. You can set the port number to any other value starting with 1024 and higher.

Can accept external connections

If this checkbox is selected, then the files on the built-in server running on the specified port are accessible from another computer.

If this checkbox is cleared (by default), then the debugger listens only to local connections.

Allow unsigned requests

For security reasons, any request to a page on the built-in server from outside CLion is by default rejected and the authorization popup is displayed.

To access the requested page, click Copy authorization URL to clipboard in the authorization popup and paste the generated token in the address bar of the browser.

However this behavior may be annoying, for example, it may block your debugging session if manual intervention is impossible. To suppress displaying the authorization popup, select the Allow unsigned requests checkbox.
