In my .zshrc
, I use the following snippet to integrate the shell's clipboard and my primary X11 clipboard. Thanks to this integration, I can cut-and-paste text to and from emacs, firefox, and the terminal without having to use the mouse.
kill-line() { zle .kill-line ; echo -n $CUTBUFFER | xclip -i }
zle -N kill-line # bound on C-k
yank() { LBUFFER=$LBUFFER$(xclip -o) }
zle -N yank # bound on C-y
Note: I use this trick on mac os x as well (with pbcopy/pbpaste instead of xclip) and thanks to Synergy my two computers share a single clipboard. Neat. But it doesn't work with readline. And I find myself using readline quite often, for example in (i)python, in gdb, in ncftp...
So here comes my question: is there a way to integrate readline's clipboard with the-rest-of-the-world ?
Of course, I'm thinkging about some .inputrc
wizardry here, but any insight/ideas would be welcome.
Personally, I run everything inside GNU screen. This gives me tons of functionality across all terminal-based programs, not just readline-based ones. It has its own paste buffer(s), which are shared between all screens in your current session, and can read/write an exchange file (configurable with bufferfile
).
Then all you need are little helpers to synchronize /tmp/screen-exchange
and the X selection. Something as simple as this would work.
# ~/.screenrc (or entered at C-a : command prompt)
bind '{' exec sh -c 'xclip -o>~/.screen_exchange'
bind '}' exec sh -c 'xclip -i ~/.screen_exchange'
Of course some nicer bindings and macros would make life easier (this requires C-a { C-a < C-a ]
to paste X selection to the terminal), but it's completely up to you.
I'd like to propose the following _xyank()
function based on ephemient's answer:
_xyank() {
CLIP=$(xclip -o)
COUNT=$(echo -n "$CLIP" | wc -c)
READLINE_LINE="${READLINE_LINE:0:$READLINE_POINT}${CLIP}${READLINE_LINE:$READLINE_POINT}"
READLINE_POINT=$(($READLINE_POINT + $COUNT))
}
What this does is to move the cursor to the end of yanked text, making it more consistent with other built-in commands.
