zshzle: aborting history search

[Georg Neis]

How can I abort history-incremental-search-backward *without* losing
the text that I'm searching for (useful when zsh says "failing
bck-i-search")?

Regards, Georg

If you want to go back to where you started your search, just press
Ctrl-G.  If you want to stay on the current line, execute almost any
editor-movement command, such as Ctrl-E, Ctrl-B, Right-Arrow, etc.

That doesn't work do what he wants; send-break discards the search text,
so, e.g., you can't resume searching for the same thing again later by
pressing the history-incremental-search-backward binding twice in a row.

This on the other hand does have the effect of saving the search text.  
So the closest you can get to having both is to invoke end-of-history; but 
that's not normally bound to anything, so you have to create a binding for 
it first.

Sorry, my description wasn't clear enough.  Here's an example:

I have a new prompt and want to execute "cat /foo/bar".  I remember
that I executed this command some days ago and thus type ^R to go
into history-incremental-search-backward mode.  Now the
"bck-i-search:" prompt appears.  There I type "cat /fo" and
"bck-i-search: cat /fo" turns into "failing bck-i-search: cat /fo"
because the command is (for whatever reasons) not in my history file.
Now I want to be able to abort the search while transfering "cat /fo"
from the search prompt to the normal command prompt in order to
complete it manually.

Regards, Georg

One thing you might look at is the LASTSEARCH zle parameter.

I think there is some funkiness with the incremental search widgets like
history-incremental-search-backward widget that you might have to be careful
about.  I had an opposite request, take text I typed on the command line and
make it go into the search buffer.  Bart provided a very helpful solution in a
thread around zsh-users/3991 (http://www.zsh.org/mla/users/2001/msg00401.html).

copy-search-as-buffer() { zle end-of-history; BUFFER="$LASTSEARCH" }
zle -N copy-search-as-buffer
bindkey '\ee' copy-search-as-buffer

Choose your own binding in place of escape-e, I just picked something that 
isn't bound by default.  The "end-of-history" isn't strictly necessary, 
but it means you aren't left with a modified buffer in the middle of the 
history after the first part of the incremental scan.

Great - that works.  I only added CURSOR="$#BUFFER" to the function's
definition.

So long, and thanks for all the answers!

I reread that... the internal function doisearch() is crying out to
use a special keymap and a recursive edit.  Currently the behaviour is
hardcoded onto certain widgets, which is why trying to get it to do
something unusual is difficult.

Possibly, doing it that way, you could get a better version of
history-incremental-search-backward as a shell function than the current
internal one.  However, there may be things that aren't so easy.

I find I use incremental search alot, so I would applaud a rewrite of the
incremental search code.  Especially if it made that code more scriptable from
zle.  There are quite a few features that might be useful to add (e.g. history
of past searches, show multiple matching history lines, color matching portion
in current line, grab word of current match, correct characters that cause the
search to fail, etc.)

P.S. Hope my message doesn't end up in spam jail again.  It took a week for my
last message to make it to the list.
