# E-scripts on gdb.

# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
#   (find-eev-quick-intro)
#   http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

<edrx> hello - if I understand correctly, if I run gdb with "-i=mi"
       in Emacs
<edrx> then gdb takes care to distinguish outputs from GDB itself,
       e.g., the outputs of "print"s and "ptype"s issued on the
       command line
<edrx> from outputs from the program being run...
<edrx> but that makes things harder to use from my default (and
       highly non-standard) way of scripting GDB, which is through
       scripts in a separate buffer, like what is shown here:
<edrx> http://angg.twu.net/eev-videos/video4-eepitch.mp4
<edrx> so - question:
<edrx> 1) is there a way to make the GDB output and the program
       output both be treated as "GDB interaction", and thus appear
       in the GDB interaction buffer?
<edrx> (oops, I forgot something: a way compatible with -i=mi)
<edrx> 2) I'd like to learn more about the -i=mi protocol... any
       starting points you'd recommend
<edrx> ?
<edrx> thanks! =)
