Please tell more, or show a screenshot.  What line numbers are those
-- the ones created by linum-mode, or something else?  Do you have a
recipe starting from "emacs -Q" for reproducing the problem?

I cannot play this.  Any chance to get some more popular format?  An
image is enough, no need for a movie.

I've attached a screenshot from the movie. It looks like there's some
custom modeline stuff going on that draws the line-number at the
extreme left. If the number gets large enough it overflows into the
fringe where it's then left because that particular part rarely gets
redrawn.

It looks to me like there are two problems:

 1. Whatever is writing the number shouldn't be trying to draw that
    far left.

 2. That part of the screen shouldn't be writable. I recently fixed a
    problem with the cursor intruding into the fringe. I expect this
    is similar.

I'll have a look into number 2, but I don't know where to start with
number 1.

There's no fringe on the mode line.  The mode line is drawn to the
full width of the window, so the fringe is not relevant to it.

Not sure I agree, see above.  I just don't understand what is drawn
there: is it "4:25"? or is the "4:" part a left-over from previous
redisplay?

It would still be useful to have a recipe starting with "emacs -Q",
the OP promised to try to provide that.

I realize that the emacs -Q wouldn't be effective since the line number is
in the middle of the mode line. With that package installed and used, the
line number gets moved to the far left towards the left fringe.

I understand that some non-default settings are needed, but just
loading the package doesn't reproduce the problem on my system.  So we
would like a precise recipe, something like

 emacs -Q
 load package X
 do something
 do something else
 observe the problem in the mode line

Can you come up with something like that?  It is important to reduce
the number of extra packages and "do something"s to the absolute
minimum, so that the problem could be more easily identified.

Thanks.

Sorry, didn’t realize there was an email I missed.

I’ll try to cook up a recipe this weekend or sometime next week.

bug#23755: 25.0.95; Emacs 25.0.95 Line number is in fringe

[James Nguyen]

A combination of that package (smart-mode-line) and setting a box around the mode line is what does it.

  (defun j/make-modeline-taller ()
    "Make the mode line taller."
    (dolist (sym '(mode-line mode-line-inactive))
      (set-face-attribute
       sym nil
       :box `(:line-width 2 :color ,(face-attribute `,sym :background)))))

Sorry, still not reproducible.  Maybe there's something else to be
done?  Here's the complete recipe I used, after downloading
smart-mode-line and rich-minority which it requires:

  emacs -Q
  (add-to-list 'load-path "/path/to/smart-mode-line-master")
  (load-library "smart-mode-line")
  (sml/setup)
  (dolist (sym '(mode-line mode-line-inactive))
        (set-face-attribute
         sym nil
         :box `(:line-width 2 :color ,(face-attribute `,sym :background))))

I see no display problems in the mode line after the above.

Sorry, I should’ve been more thorough (commenting out that line fixed the problem for me in my setup). I’ll try to get a complete recipe up.

I just tried this on the NS port and it leaves stuff behind. The line
number goes over into that left-hand section, which is fine since it's
not the fringe.

Aside from that, the digits seem to be placed wrongly. Sometimes
they're fine, other times they're all wonky. I've attached a
screenshot where it's displaying 404, but it looks like the 0 is too
far left, and the second 4 is cut off, and another screenshot after I
paged down and you can still see the left edge of the zero.

I don't see any other characters that are obviously displayed wrong.

I don't know how to tell what font it is, but I suspect it's
variable-width and Emacs doesn't notice when they change size. For
example, the misplaced 0 in 404 occurs after scrolling from a number
starting with 3, and the 3 appears to be narrower than the 4. The
second digit doesn't move right to compensate for the larger first
digit. When it finally does move, it leaves artifacts behind.

Changing line-width to 1 in your code fixes it.

The font is https://github.com/madmalik/mononoki which I believe is fixed-width.

Yeah, I realised after typing that that it probably has nothing to do
with the width of the characters, and everything to do with Emacs not
handling the larger box round the modeline.

And FWIW, I'm using a different font. It's probably Menlo, which is
also fixed-width.

Do we still need a recipe from me if Alan can reproduce this?

If Alan can debug this, no.  If I need to debug this, yes.

Btw, did previous versions of Emacs and/or previous pretests of 25.1
have the same problem, or is this new with 25.0.95?

Thanks.  I cannot judge this, so please wait for a few days, and if no

Then I guess it's either NS-specific or specific to the fonts you are
using.

So what, the NS port cannot even display text correctly?

That cannot be true in general, since Emacs displays variable-pitch
fonts correctly since v21.1.

That can only happen if the font lies to Emacs about the dimensions of
the character glyphs.

> Changing line-width to 1 in your code fixes it.

Which means the font does NOT lie, and thus the fact that some
characters are narrower than others is NOT the reason.

That's left over from a previous redisplay.

Thought so, thanks.  Still, just loading the package and activating it
doesn't reproduce the problem on my system, so something else is at
work here.
