One other alternative history search widget

One other alternative history search widget

[Sebastian Gniazdowski]

Hello
I've adapted the earlier announced zcurses based selection list so
that it works from within ZLE. It can be bound to the typical "^R" key
combination to provide history search. It uses whole screen and
highlights matches, what can be seen here:

So, that's one other alternative history search widget, available here:
https://github.com/psprint/zsh-navigation-tools

One problem is that it puts multi line history entries into one line,
introducing '\n' where the newlines should be.

Best regards,

Is that a problem with "history -nr" output, or is it a problem with
the representation necessary to allow curses-based list selection?

It's rather difficult to implement multi-line entries in the curses
list. It doesn't support them right now, so the format gave by history
call is a plus. One quick idea is to keep array ENTRY_MULTIPLICITY
which would hold count of "\n"-s for each list entry. I would
implement that in separate n-list-multi-line. Line-wise n-list is fine
in the line-wise Unix world, but like in the history case, there are
situations where that isn't fully enough.
