Re: Emacs mode for GDB

[Miles Bader <miles@lsi.nec.co.jp>]

I tried your mode, and it seems generally like a nice idea.

Some comments:

(1) I get the following error regularly:

       error in process filter: gdb-output-burst: Symbol's function definition is void: gdb-display-end
       error in process filter: Symbol's function definition is void: gdb-display-end

    Indeed there seems to be no such function `gdb-display-end'.

(2) Completion doesn't work on the gdb command line like it does in
    the standard gdb-mode.

(3) The file `gdb.el' is apparently constructed in large parts from the
    existing `gud.el', with much of the functionality of gud removed (in
    particular, support for non-gdb debuggers).  Is that necessary?

    If emacs were to use your gdb.el unchanged, it would result in a
    huge amount of duplicated code between gdb.el and gud.el; it would
    be nicer to either continue to use gud.el, with new features added,
    or otherwise avoid code duplication.

(4) With all the windows displayed, it requires a lot of space.  It
    would be nice to have some way of specifying which windows get
    used -- for instance, the breakpoint window can be displayed only
    if there are breakpoints, and when tested it, I didn't need the
    backtrace, or I/O windows either, so I'd like to be able to disable
    them.

(5) You should keep the historical author information in the file header
    comment.
