Package: bash
Version: 3.1dfsg-8
Severity: normal
I wanted to use set-mark as part of a readline key binding. One
simple example I tried, which should have worked:
bind 'Control-v: "[EMAIL PROTECTED]&\C-x\C-x"'
This should make Control-v insert an & at the end of the line but
leave the cursor in the current position. However, it does not work.
At first I thought that the set-mark command would not work in a key
binding. However, I discovered that I could bind another key to
set-mark, and that key would work:
bind '"\C-x\C-m": set-mark'
bind 'Control-v: "\C-x\C-m\C-e&\C-x\C-x"'
I furthermore discovered that if I bound some other function or string
to C-@, it would not work in a macro either:
bind '"\C-@": "at"'
bind 'Control-v: "\C-@"'
Finally, I discovered that some key sequences only work if bound via
the longer Control-$char syntax, and others only work if bound via
"\C-$char". For instance, Control-v only works if bound as Control-v;
if bound as "\C-v" it will continue to point to quoted-insert (both in
a key binding and interactively). Control-@, on the other hand, only
works if bound as "\C-@"; if bound as Control-@, it will continue to
point to set-mark (interactively; it does not work either way in a key
binding).
The eventual goal, which I managed to achieve after these various
workarounds:
# Make Control-v paste, if in X and if xclip available
if [ -n "$DISPLAY" ] && [ -x /usr/bin/xclip ] ; then
# Work around a bash bug: \C-@ does not work in a key binding
bind '"\C-x\C-m": set-mark'
# The '#' characters ensure that kill commands have text to work on; if
# not, this binding would malfunction at the start or end of a line.
bind 'Control-v: "#\C-b\C-k#\C-x\C-?\"$(xclip -o -selection
c)\"\e\C-e\C-x\C-m\C-a\C-y\C-?\C-e\C-y\ey\C-x\C-x\C-d"'
