Question

I can step along with gdb, but I have to give the “list” command every time I want to see where I am in source code.

(gdb) next
351     int right = get_variable(right_token, right_id);
(gdb) list
346         op = "<>";
347         right_id = parse_id_or_crash();
348     }
349     Token * right_token = tokens[parser_index - 1];
350     int left = get_variable(left_token, left_id);
351     int right = get_variable(right_token, right_id);
352     if (op == "<")
353         return left < right;
354     if (op == ">")
355         return left > right;

It would be great if gdb would automatically list the source code after every step. It would also be great if gdb could indicate where in the source code I am (like with a “->” or something). Seeing only one line of code at a time makes me a little claustrophobic.

Use gdb TUI mode http://sourceware.org/gdb/onlinedocs/gdb/TUI-Overview.html#TUI-Overview
You can enter or leave the TUI mode with C-x A key binding.
