I combined some of my old stuff into the poor-man's
solution I spoke of earlier. If you have two shortcuts
- one to go to Emacs from the shell - and one to invoke
`pipe-buffer' (in Emacs), it is not that poor.
I could actually go to Emacs at the end of pipe-out...
but that wouldn't be perfect either, because in Emacs,
one would still have to invoke `pipe-buffer'. So, I'll
leave it double imperfect requiring two strokes. But
the stroke to go to Emacs should already be there, and
be habitually used - and, sudden (unasked for) shifts
between applications are a pain.
To be non-IPC I like this solution!
The reason for `do-show-file' is so that it won't ask
if you want the new version each time.
In Emacs:
(defun do-show-file (file)
(interactive "f file")
(progn
(switch-to-buffer
(find-file-noselect file t)) ; nowarn
(revert-buffer t t nil) ; ignore-auto noconfirm preserve-modes
(message nil) ))
(defun pipe-buffer ()
(interactive)
(do-show-file "~/.emacs.d/piped-out.txt") )
In zsh:
#!/bin/zsh
pipe-out () {
pipe_file=~/.emacs.d/piped-out.txt
if (( $# )); then # usage: $ pipe-out `cmd`
input=$* # or: $ pipe-out `cmd1` plain `cmd2` (etc.)
else
read -d \\0 input # $ cmd | pipe-out
fi
echo $input >> $pipe_file
}
The code is here - fixes will be put there, as well:
