end-of-line not working as advertised?

[Robin Lee Powell]

Please cc: me as I'm not on the list.

beginning-of-line works, in that repeated presses take me to
successive line beginnings.  end-of-line, not so much.  See video:

The man page bits:

  end-of-line (^E) (unbound) (unbound)
   Move to the end of the line.  If already at the end of the line, move to the end of the next line, if any.

For me, it works. And I didn't know this feature...
I've tried on:

for i in 1
do
echo $i
done

You're using an emacs-mode key binding in vicmd mode.  In vicmd mode,
the position of the cursor isn't allowed to move beyond the last
real character on any line, so end-of-line never actually reaches
(what it defines as) the end of the current line, and therefore never
advances to the next line.

If you try it in either actual emacs mode, or in viins mode where you
have also defined it, it works as documented.

Nothing is guaranteed to work exactly as documented if you mix the
widgets from different modes; vicmd mode is especially unlike either
of the others.

OK, fair enough.

What I actually *wanted*, btw, was a way to get to the beginning or
end of a multi-line command; these were just the best versions I
saw.

Try end-of-buffer-or-history ... yes, it's still an emacs-mode widget,
but because it deals with history as well as buffers it handles vicmd
a little better.

Or try this:

vi-next-end-of-line() {
  local curs=$CURSOR
  zle vi-end-of-line
  if (( curs <= CURSOR )); then
    NUMERIC=2 zle vi-end-of-line
  fi
}
zle -N vi-next-end-of-line
bindkey -a ^E vi-next-end-of-line

That is *SUPER* helpful!  Thank you so much.

This is actually a better way, I think:

vi-next-end-of-line() {
  # In vicmd mode, CURSOR can never be at EOL, and in fact can't
  # be closer than 2 positions to the left of EOL, because the
  # on-screen visible cursor is always one place to the right of
  # the value of CURSOR and never "over" the newline itself.
  if [[ $KEYMAP = vicmd ]]; then
    (( CURSOR++ ))
  fi
  if [[ $BUFFER[CURSOR+1] = $'\n' ]]; then
    NUMERIC=2
  fi
  zle vi-end-of-line	
}
