Font lock in GUD buffer

Font lock in GUD buffer

[Nick Roberts]

I would like to be able to vist file locations from the GUD buffer.

By way of illustration consider a program myprog compiled with -g3 (macro
information) and with the header math.h included:

(gdb) start
Breakpoint 1 at 0x80485bb: file myprog.c, line 83.
Starting program: /home/nickrob/myprog 
main (argc=1, argv=0xbfe13914) at myprog.c:83
(gdb) info macro M_PI
Defined at /usr/include/math.h:355
  included at /home/nickrob/myprog.c:4
#define M_PI 3.14159265358979323846
(gdb) 


If you do "M-x compilation-minor-mode" the locations myprog.c:83,
/usr/include/math.h:355 and /home/nickrob/myprog.c:4 are in red and underlined.
If you click on them you can visit them in another buffer.  Of course, you have
to turn off compilation-minor-mode to continue the debug session.  Also when
you do this you find that the mouse-face and help-echo have disappeared from
previous input commands, presumably due to some interaction with
font-lock-mode.

Does anyone know how to do this cleanly?

compilation-shell-minor-mode?

Thanks.  It's nearly the right thing but the fontification on the links
disappears after every input GDB command and I have to do "M-x
font-lock-fontify-buffer" to get it back.  I notice that if I run GDB from
within a shell buffer the fontification on the links doesn't disappear but it
still does for the mouse-face and help-echo from previous input commands.

It looks like compilation-shell-minor-mode is rewriting the font-lock rules,
not just adding to them.
