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.

You can see these breakpoints with the GDB maintenance command `maint info breakpoints' . Using the same format as `info breakpoints' , display both the breakpoints you've set explicitly, and those GDB is using for internal purposes. Internal breakpoints are shown with negative breakpoint numbers.
Is there a gdb command to finish a loop construct? Execute until on the last line of the loop, or until NNN where NNN is the last line of the loop. (gdb) help until Execute until the program reaches a source line greater than the current or a specified location (same args as break command) within the current frame.
To print lines from a source file, use the list command (abbreviated l ). By default, ten lines are printed. There are several ways to specify what part of the file you want to print; see Specify Location, for the full list.
If you want to execute the entire function with one keypress, type "next" or "n". This is equivalent to the "step over" command of most debuggers. If you want gdb to resume normal execution, type "continue" or "c". gdb will run until your program ends, your program crashes, or gdb encounters a breakpoint.
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.

hook-stop
define hook-stop
l
end

In addition, a pseudo-command, ‘stop’ exists. Defining (‘hook-stop’) makes the associated commands execute every time execution stops in your program: before breakpoint commands are run, displays are printed, or the stack frame is printed.

Highlight the current line
This is the only thing missing to completely replace the buggy -tui mode completely.
It is currently not possible without Python scripting: https://sourceware.org/bugzilla/show_bug.cgi?id=21044
