Narrow cursor at end of line?

Narrow cursor at end of line?

[Adam Sjøgren]

XEmacs indicates that point is at the end of a line by making the cursor
slightly less wide. How do I make GNU Emacs do the same?

I guess you could change the cursor-type when it's at the end of line.
See the variable: cursor-type

Ah, nice - thanks for the pointer.

I guess what I want to do is to have cursor-type set to (bar . 6) at the
end of the line and t otherwise. Perhaps something like:

  (defun asjo-indicate-end-of-line ()
    "Change the cursor to a narrow one when at the end of line"
    (if (eq (point) (line-end-position))
        (setq cursor-type '(bar . 6))
      (setq cursor-type t)))

I would need a hook called every time point is moved (or any time it is
moved to/from end of line) or add an advice to something, I guess?

I have looked though the list found with M-x apropos hook, but couldn't
really a good candidate...


  Best regards,

You can do that after a command is executed: post-command-hook

Thanks to both of you - that was exactly the help I needed.

post-command-hook?

You mean

     (setq cursor-type (if (eolp) '(bar . 6) t))

Actually, it's only every time the cursor is moved (point can be moved
many times internally over the course of a single command).  I.e. at
every redisplay.  There is sadly no hook for that (yet?), but you can
use post-command-hook as a good first approximation.
