vi-history-incremental-search?

[Steve Talley]

Hello,

I am using the vi keymap (bindkey -v).  I have these lines in my
.zshrc:

    bindkey -M vicmd "?" vi-history-search-backward
    bindkey -M vicmd "/" vi-history-search-forward

I really like the ability to see incremental searches, so I changed
this to:

    bindkey -M vicmd "?" history-incremental-search-backward
    bindkey -M vicmd "/" history-incremental-search-forward

Unfortunately, now "n" (vi-repeat-search) and "N" (vi-rev-repeat-
search) don't seem to work after the search is completed.  That is,
they don't perform the same search from that point in the history.

For example, with this history:

    ...
    100 echo foobar
    101 echo blah
    102 echo woofoo

When I use vi-history-search-backward to search for "foo" (matched at
102), I can use "n" (vi-repeat-search) to perform the same search
again (matched at 100).  But if I initially use
history-incremental-search-backward to search for "foo", then "n"
(vi-repeat-search) doesn't continue the search for "foo".

Is there any way to modify either vi-history-search-* or
history-incremental-search-* to come up with a hybrid
vi-history-incremental-search*?

Thanks,

Steve

Unfortunately, without rewriting some C code, it's very difficult.

Even in emacs mode you can't exit from incremental search and then resume
the same search again later.

You can tell the search what string to begin searching for, by calling
(in a widget function) e.g.
	zle history-incremental-search-backward foo
but there's no way at the end of a search to capture and save the string
that was last searched for, so the ability to set the starting string
doesn't help much.

You *could* implement your own incremental search, modeled after the
input loop in the incremental-complete-word function that's in the
distribution, but that would get pretty hairy.

The easiest solution would probably be to change the two functions to
use the same last-search variable instead of two different ones.  The
only downside to this is if someone out there uses both search functions
and enjoys having a different search default in each one.  I personally
see no problem with combining them.

I'm not sure what you mean here.  Type Ctrl-R twice and it will start a
new search with the previous search string.

Hrm, I swear I tried it in 4.0.6 and it didn't work.  But I just tried
again (with 4.0.3, I haven't upgraded the machines at work yet) and it
worked, so I must have flubbed something last night.

In that case, Steve can do:

function vi-repeat-incremental-search-backward {
 bindkey -e
 zle -U $'\C-r'
 zle history-incremental-search-backward
 bindkey -v
}
zle -N vi-repeat-incremental-search-backward
bindkey -a N vi-repeat-incremental-search-backward

(The "bindkey" commands shouldn't be necessary, but the keymap for h-i-s-b
is messed up when you enter it from vicmd.)
