Quite some time ago ian@unipalm.uucp (Ian Phillipps) wrote
|
|
about a handy way to set up a csh command line editor using vi.
|
|
I have been using it faithfully, until my vi changed from
|
|
"Version 3.7, 6/7/85." to "Version SVR3.1". Now, things are screwy
|
|
and it basically doesn't work. Does anyone know how to fix this
|
|
problem (other than switch away from csh or change vi) ? Incidentally,
|
|
I consider this command line editor thingy to be the best thing since,
|
|
say, money subplanted bartering ?
|
|
|
|
I include Ian's posting below, since it is short:
|
|
|
|
The following works with the C-shell. It was posted about two years ago
|
|
on Usenet, and the poster then said that its origin was lost in the
|
|
mists of time. Here goes:
|
|
|
|
You need an alias in your normal setup, thuswise:
|
|
|
|
alias r source ~/cmd/redo
|
|
|
|
Type "r" and you'll be in "vi" open mode, editing the last command. You can
|
|
use any vi/ex commands (even go into visual mode): when you hit Return, the
|
|
current line will be executed by the C shell.
|
|
|
|
The "redo" file is as follows. **IMPORTANT NOTE** To avoid mangling in
|
|
the posting, I've replaced a Carriage Return with "^M" and an ESC with "^["
|
|
in ex's "map" command:
|
|
|
|
----cut here and replace control characters---
|
|
# Edit history list at line containing last command (open mode).
|
|
# Get up to 22 most recent commands.
|
|
# To work properly, put in .login: alias r source /usr/local/bin/redo
|
|
# Author unknown.
|
|
history -h 22 >! /tmp/redo.$$
|
|
|
|
# Make CR map to :wq! and start ex quietly at 2nd to last line in open mode.
|
|
ex - '+map ^M :.wq\!^[|set redraw|$-1 open' /tmp/redo.$$
|
|
|
|
# Insert into history without executing.
|
|
source -h /tmp/redo.$$
|
|
|
|
# Clear out temporaries.
|
|
/bin/rm -f /tmp/redo.$$
|
|
|
|
# If thing chosen to redo is the redo alias itself then DON'T redo it.
|
|
if (!-2:0 != !!:0) !!
|
|
----cut here----
