[Cgdb-devel] Bug: the default readline hotkeys Alt-X don't work in cgdb

[Kuang H. <ic...@gm...>]

Hi all,

I'm a new user of cgdb and find it very useful. The vi key binding is
very nice, too, since I'm a vim user. Thank you, cgdb developers!

I'm using cgdb 0.6.4 on a linux box (Ubuntu 8.04), with libreadline
v5.2. The default readline hotkeys Alt-X (e.g. Alt-P/N for
history-search-backward/history-search-forward, Alt-F/B for moving a
word forward/backward) do not work in cgdb on my machine. Any Alt-X
combination key in the gdb window will result in switching to the
source code window, just as an ESC would do. I've tried to read cgdb's
source code to figure out why, but the code is more complex than I've
thought. Any enlightenment would be welcome.

Also, I personally like to define PageUp/PageDown in my ~/.inputrc to
do the same thing as Alt-P/N, but since PageUp/PageDown have been used
by cgdb to scroll the screen, I could not use these hotkeys as I like
to. I've changed the code to fix that (for myself), but I guess there
is no generic solution since all the hotkeys cgdb use are hard coded
into the source.

Best regards,
