    Hello zsh-workers :))

    I haven't took a deep look at the code, but I think that ncurses
is used only in the terminfo module and, obviously, in the few screen
handling routines of zsh, and I will make a suggestion: how about
switching to slang? I think that it's fully ncurses compatible, less
bloated and full featured.

    I don't know if it is really needed, because I don't know the use
of ncurses throughout the zsh code, but IMHO slang is far better.

    Moreover: how is curses used in zsh? Is *really* needed to make
zsh dependent of the curses library or could it statically link the
few needed parts?

    I keep on with my idea of putting zsh into a tiny embedded system
O:))) Thanks in advance for you opinion :)

These "few routines" are the heart of zsh ZLE :-) Remove them and half
of the zsh functionality is lost.

zsg does not actually use either termcap or curses. It needs them only
to get terminal capabilities; for this it is using several termcap
functions that are emulates by curses as well. 

curses module just provides convinient access to terminal capabilities
using curses names, no more.

There is no need to switch to slang. Either termcap or curses are
available on every system; slang is not. Given that we do not use any of
the features provided by slang (for that matter we do not use any of the
features provided by termcap or curses either :-) there is no reason to
use it.
