12 The Debugger Tool

12.7 Performing operations on frames in the stack

Choose Frame > Documentation to display the Common Lisp documentation for the object pointed to by the current frame, if any exists. It is printed in a special output browser window.

Choose Frame > Find Source to search for the source code definition of the object pointed to by the current frame. If it is found, the file is displayed in the editor: the cursor is placed at the start of the definition. See Chapter 8, "The Editor" for an introduction to the editor.

Choose Frame > Trace to display the standard Trace menu. This lets you trace the function in the selected frame in a variety of ways: see Section 3.10 on page 48 for details.

Choose Frame > Restart Frame to continue execution from the selected restart frame. The action that is taken when choosing this command is printed with each restart frame in the Backtrace area. As a shortcut, you can click on the Restart Frame button at the bottom of the debugger tool rather than choose this command. Note that View > Restarts must be enabled for this command to be available: see Section 12.9.1 for details.

Choose Frame > Return From Frame to resume execution from the selected frame. You are prompted for a value to return from the selected frame. This option allows you to continue execution smoothly after you have dealt with the error which caused entry into the debugger. As a shortcut, you can click on the Return From Frame button at the bottom of the debugger tool rather than choose this command.
