I am displaying an info file in emacs. But when I use the arrow keys to move up and down
the document I get
Debugger entered--Lisp error: (beginning-of-buffer)
signal(beginning-of-buffer nil)
previous-line(1 1)
funcall-interactively(previous-line 1 1)
call-interactively(previous-line nil nil)
command-execute(previous-line)
Debugger entered--Lisp error: (end-of-buffer)
signal(end-of-buffer nil)
next-line(1 1)
funcall-interactively(next-line 1 1)
call-interactively(next-line nil nil)
command-execute(next-line)

Do you see that when you start Emacs with `emacs -Q'?
Do you mean that each time you hit a vertical arrow key you get such an error, or just when you do that at the beginning or end of an Info node. The latter is expected.

That's how it should be, or how it is anyway, perhaps you
configured the debugger?
try
$ emacs -Q
then eval (info "(Emacs)")
and see it the problem remains.

Nat when using "emacs -Q".
Only when I reach the beginning or end of an Info node. The problem is that I also get a
*backtrace* buffer, with the text described.

No, the problem vanishes. Must be something in my init file then.

I can't reproduce this problem. Could you give some more detailed steps
to reproduce it? How much content does the Info file have? Can you
reproduce the problem from "emacs -Q"? Thanks.

I had debug-on-error. Am now doing a cycle function for debug "on"
and "off".
Can I improve on the following?
(defvar debug-cycle-state 1)
(defun debug-cycle ()
(interactive)
(pcase typh-frame-size-state
(1 (setq debug-on-error nil)
(setq typh-frame-size-state 2))
(2 (setq debug-on-error t)
(setq debug-ignored-errors nil)
(setq debug-on-message "unescaped character literals")
(setq typh-frame-size-state 1)) ))
(global-set-key (kbd "H-g") #'debug-cycle)

Did you turn on debug-on-error, per chance?

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Here we see how where the problem originated, because
`debug-ignored-errors' by default contains both
beginning-of-buffer and end-of-buffer.
Here we also see what happens when you muck around with global
variables from defuns...

It also overrides the variable ‘debug-on-error’.
How would be best to have the function?

I am really getting confused about debug-ignored-errors and how to
change debugging options "on" and "off" in my init file.

I would like to debug all errors (including those that are customarily ignored)
using option 2. And for option 1, I want to put all debugging off.
debug-ignored-errors is messing me up.

OK, then set `debug-on-error' to `t' and
`debug-ignored-errors' to the empty list.

OK, set debug-on-error to nil.
I disencourage from doing this BTW, since many of the ignored
so-called "errors" are really better of being ignored...

Are you sure that's where it started? :)

Most of the time setting `debug-ignored-errors' to nil is not necessary
and can be quite annoying. You may want to remember the variable name
and have a command at hand to change the value, but IME having it nil is
not a nice default choice.

Well, ideally it would be good to have an additional option that
puts debug-ignored-errors to how it was set up initially.

Have the point moving to the top of the buffer should not really be considered
an error. I agree that nil is not a very good choice. too

You can store it another variable before you change it, then
use that to reset.

Well, Emacs is from 1976. People were thinking of it like
programmers. That's actually part of the appeal, even now.
In the user experience sense, it isn't an error, no.
People aren't computers, thanks heaven.
But luckily, this computer/programmer/user discrepancy, which
is unavoidable if one wants to have a common interface, this
particular situation is very easy to solve ... even/especially
with programming!
And the solution spells ... *drumroll* ...
debug-ignored-errors !

What usually happens in that I make a mistake in my emacs init file and emacs complains.
If after loading emacs, I call (setq debug-on-error t), would the debug on the loading error
work? Or would I need ho have (setq debug-on-error t) before emacs is called.

Seems everything got started the same way. From a fuckup. :)

I'm not following, sorry...
Correct the mistake without involving the debugger is what
I would do, anyway.

Suppose I run the command "emacs" on a terminal and there is a problem in my init file.
If I want to debug the error, could I enable (setq debug-on-error t) from emacs.
Or would I have to include (setq debug-on-error t) in my init file before calling
"emacs" on the terminal?
> Correct the mistake without involving the debugger is what

Or course, if one can.

Isn't `t' the default?

Ah ok, I think I recall that the default value had been changed some
time ago.
Yes, you can set the variable at the beginning of your config file or
wherever you want, and reset it later if you want, at the end of your
file, or in `after-init-hook'.
Regards,
Michael.

It isn't. Trying to move _past_ that is.

Not sure what the discussion is about here, but
AFAIK, the default value of `debug-on-error' has
always been nil.
