Next: , Previous: Frame Selection, Up: Interactive Debugger Frame Information

The following commands return detailed information about the currently selected frame.

— Debugger Command: info frame

Display a verbose description of the selected frame. The information that this command provides is equivalent to what can be deduced from the one line summary for the frame that appears in a backtrace, but is presented and explained more clearly.

— Debugger Command: info args

Display the argument variables of the current stack frame. Arguments can also be seen in the backtrace, but are presented more clearly by this command.

— Debugger Command: position

Display the name of the source file that the current expression comes from, and the line and column number of the expression's opening parenthesis within that file. This information is only available when the positions read option is enabled (see Reader options).
