inhibit-message, "Beginning of buffer" / "End of buffer" messages

inhibit-message, "Beginning of buffer" / "End of buffer" messages

[John Magolske]

Hi,

I'd like to suppress the "Beginning of buffer" / "End of buffer"
messages that show up when the cursor in the minibuffer is moved all
the way to the left & all the way to the right. It seems that setting
"inhibit-message" might take care of this, but I'm having no luck with
entries like this in my init.el :

    (setq inhibit-message t)

...the "Beginning of buffer" / "End of buffer" messages still show up.

`C-h v inhibit-message RET` shows:

    inhibit-message is a variable defined in ‘C source code’.
    Its value is t

    Documentation:
    Non-nil means calls to ‘message’ are not displayed. They
    They are still logged to the *Messages* buffer.

Can "inhibit-message" suppress these messages in the minibuffer?
I understand it's a new functionality as of Emacs 25, which I've
installed from git:

    % /usr/local/bin/emacs --version
    ~/code/emacs-781770b4dcfe44b255e94e16479fd14633803640 1:01
    GNU Emacs 25.0.50.1

TIA for any advice,

John

These "messages" are actually errors, so `inhibit-message' has no effect
(and I think you would regret sooner or later when setting
`inhibit-message' globally to t).

AFAICT there is no user option to achieve what you want.  I would try it
like this:

--8<---------------cut here---------------start------------->8---
(defun my-ignore-bet-end-of-buffer--around-ad (f &rest args)
  (condition-case nil
      (apply f args)
    ((beginning-of-buffer end-of-buffer))))

(advice-add 'left-char :around
            #'my-ignore-bet-end-of-buffer--around-ad)

(advice-add 'right-char :around
            #'my-ignore-bet-end-of-buffer--around-ad)
--8<---------------cut here---------------end--------------->8---


Regards,

Michael.

Ah, I see. At some point I'll look into what sort of messages
'inhibit-message' acts on. For now, what I'm most concerned with is
the "Beginning of buffer" / "End of buffer" popping up when in the
minibuffer. Particularly when in evil-mode on the ex command line and
the command gets overlayed with "End of buffer", which I find jarring.

I figured as much :)

And that works perfectly! 

Thanks,

John

Use the Elisp in this file:

    http://user.it.uu.se/~embe8573/conf/emacs-init/error.el

Then modify the data of this data structure to fit
your needs (the errors you mention are already in it):

    (setq debug-ignored-errors
          '(quit
            beginning-of-line    end-of-line
            beginning-of-buffer  end-of-buffer
            end-of-file
            buffer-read-only
            file-supersession) )

And: Mary X-mas to Elisp X-men hackers all across
the universe!
