Dear All,
Bash has a function called redraw-current-line. It's listed in the
core html documentation along with instructions of how to set up a
key binding to it. My question is: How can I execute it from within
a script, preferably without monkeying about with the user's key
bindings?
Documentation:
http://www.gnu.org/software/bash/manual/bashref.html.gz
(This will display in Firefox, having automagically gunzipped,
however other formats are at:)
http://www.gnu.org/software/bash/manual/bash.html
Example:
bind Control-r:redraw-current-line
Now I can happily manually input Control-r, which will have no
visible effect unless the command line has been monkeyed with, in my
case because something was written to the terminal. What I'd like to
do is to write something to the terminal (a hint, triggered by a
programmable tab completion) and then redraw the command line so that
the line that the person was typing appears again. At present I can
end the script by telling the user the key binding for redraw-current-
line, and they can press that and it works as expected. So the
concept is right, I just need to find out how to automate it.
Btw, do you know whether this only works when bash is in e-macs
mode? Will I have to find out what mode bash is running in, convert
to e-macs, redraw-current-line, then convert back again? I suppose
that's easy enough for me to find out...
Regards, Max
