show timestamp during history search ?

show timestamp during history search ?

[Andy Spiegl]

Hi, just had an idea:  I'd consider it really useful while searching
backwards through the shell history to see the time when this command
was actually run.  I've got EXTENDED_HISTORY set, of course. :-)
Unfortunately I am clueless on how to implement this feature.
Maybe some kind of function bound to ctrl-r ?

Any help is appreciated!

Have a nice weekend!
 Andy.

zle-isearch-update() { zle -M "$(history -i $HISTNO $HISTNO)"; } 
zle-isearch-exit() { zle -M ''; }
zle -N zle-isearch-update
zle -N zle-isearch-exit


Bit annoying, I was hoping for something more complicated.  Can probably
be enhanced.

For long commands (i.e. which take several physical lines), some lines
are not cleared when typing ^U (kill-whole-line).

Very cool, thanks!
I trimmed it down to date+time like so:
 zle-isearch-update() { zle -M "$(history -i $HISTNO $HISTNO | awk '{ print $2,$3 }')"; }

Then, I tried to put it to the right side of the screen (like RPROMPT)
but failed.  Probably not a good idea anyway because most of the time
there won't be enough space.

Thanks again!
 Andy.
