Cannot see what is written on modeline

Cannot see what is written on modeline

[wael-zwaiter]

When I call "emacs27 -q", the mode line has both background and foreground white.

I thus cannot see what is written on the modeline.

It costs extra to be able to read the mode-line. ;-)

Does it really!  The modeline is as expected when the cursor is on another window.
The problem is the colour contrast when one looks at the working buffer.  The background
in light grey, and the foreground is white.  The display looks all white on some screens.

This is sooo 2000s. Nowadays you pay to /disable/ a (dis?)service [1].
To be fair, it seems to have been a bug [2]. Nonetheless, somewhat...
Freudian.

Currently the colours are

foreground: #ffffff
Background: #bfbfbf (grey75)

The contrast ratio for such combination is 1.8,

This level does not even reach the minimum contrast of 3.0 for large scale text.

Emacs should start caring about colour contrast by itself.

Where did those colors come from? they are not the default colors.

I took them from calling

   M-x customize-face mode-line

So you your self asked Emacs to use these colors? then I think Emacs
shouldn't second-guess you.

There could be a place to warn the user that these colors mean low
contrast, when the user is about to save the changes.  Would that be
good enough?

I did not ask Emacs for them, they were populated there somehow, and
simply reported on their values.

Was using "emacs27 -q" (--no-init-file) to debug some problem with some
.el files I was working on.  I agree with you that if the user insists,
they should take effect.  Although a remark would help a user think more
about the options he uses.

That would be good enough.  But the case of using "emacs -q" should impose
good contrast by default.  Some have suggested that it could have been
the X Environment that set up the mode-line that way.

Then I suggest to file a feature-request bug report asking for such a
feature.  Although I now understand that it wasn't you, but some X
resource on your system that requested this color combination, in
which case adding such a warning will not help.

I think that the OP is saying that he looked up the colors through M-x
customize-face, not that he *setted* them.

I asked him to make some experiments to determine the source of those
colors, but his last message in our exchange contained only quoted text
from previous messages.

In general, that feature could avoid the scenario where by accident or
ignorance the user sets a background and foreground so similar to each
other that the customize-face interface itself becomes unreadable.

Instead of asking before applying the changes, is could be better to ask
after the changes are visible, using a temporary "safe" color
combination on the minibuffer: "your changes look like this, do you want
to keep them?".

I replied with the following

-q --no-x-resources Problem goes away

-q --no-site-file Problem exists

-q --no-site-lisp Problem exists

It was then determined that X Resource was doing that.

It isn't practical to set resources that are used by every application.
You'll need to add or override some settings for particular applications.

Then you (or something you loaded) customized that face.

The point in telling you about `M-x customize-face' was
that you can use that to revert to the uncustomized
(default) appearance, and you can use it to customize
faces to any appearance you like.

Should emacs allow X-Resource customisations when the result is not good
because it does not take into account computations based on the contrast
ratio?

I am of the view that emacs should by default set such things as the mode-line
itself and not allow X-Environment to take over.

Yes, of course. Why Emacs should ignore what it is requested to do?

The user is always in power.

The purpose of .Xresources is to take over the default colors of Emacs
(or any other X application).

Better ask yourself why do you have an .Xresources file with settings
you don't like.

Definitely.

How should a program know whether some config is intentional?
Given the dazzling diversity of displays out there, "not good"
can depend on many factors.

The contrast ratio is a good metric to determine suitability.  For instance,
the AAA requirement constitutes a contrast ratio of 7:1 to compensate for
contrast sensitivity loss by low-vision users with a vision loss of 20/80
or more.

Do you observe the problem if emacs is started with -Q instead of -q ?

Re: Cannot see what is written on modeline

It happens when using "emacs27 -q".

With "emacs27 -Q" the contrast is not so bad and I can see the mode line text.

Ok. So try one after another these combinations:

-q --no-x-resources

-q --no-site-file

-q --no-site-lisp

and note which one causes the problem go away.

I suspect your distro installs some customization that affects the
modeline appearance.

So it sounds like it's your X Resources.

But here's another thought, since you said
that it happens only (or more strongly?) when
the window with the mode-line is selected:

`M-x customize-face mode-line'

For the mode-line when the window is _not_
selected:

`M-x customize-face mode-line-inactive'

Re: RE: [External] : Cannot see what is written on modeline

[wael-zwaiter]

Could emacs internally figure out the colour settings and determine if the contrast
between the foreground and background is high enough.  And if not high enough to change
the foreground and background colour.  Particularly when user supplies the -q option
whilst debugging.

It could but that would prevent such settings being made on purpose.
AFAICT your current problems are due to Xresource settings, which are
usually things the user sets explicitly, so it would be odd for Emacs to
ignore/override explicit user settings.

`-q` is not for debugging: `-Q` is.

If they want them on purpose, could they not do them within their init file,
and let emacs use accessibility criteria when not set explicitly in the emacs
init file.

> > Particularly when user supplies the -q option whilst debugging.

Because only -Q avoids processing X resources.

Usually used -q to see what happens when no init file is loaded.  Was
not aware that emacs relies on X Resources, but that emacs handles
customisations internally, not picking things for mode line from
X Resources.  I am of the point of view that emacs should take care
of mode-line, because the emacs mode line should not form part of the
window environment.  The mode-line is there to assist the user with
important buffer specific details related to emacs.  In that regard,
accessibility considerations should trample other things, unless reset
from emacs customisation or by modifications to emacs init file.

Many people do not fully understand the ramifications emanating from the
setting of the X Environment Resources that applies to all window environments.

Most likely he installed Emacs later on, without bothering with the X Resource
Settings during OS installation.

[Robert Thorpe]

I think there is some confusion about X resources here.

By default the X windowing system doesn't set any of the things that
we've been talking about.  If you start with X and no special
configuration then Emacs uses the Emacs default settings.

X resources are something that someone sets.  In this case you have set
an X resource for some reason that has interferred with Emacs'
functioning.  The X windowing system itself has not created that
setting.  Someone doing configuration has created that setting.

Maybe you copied an X resource snippet from the internet and that has
caused this.

At an outside chance it may be the distro that you are using that has
added this X resource.  If so, that is a bug in the distro and should be
reported to the distro maintainers.

To check whether that is the cause you can create a new user account.
If "emacs" is run from that new account it should look like "emacs -Q".
If it does then a user-added X-resource is the problem.  If the same
contrast problem occurs then the the distro probably has a bug.

This is the first time I've heard of a problem like this for Emacs.  I
don't think it warrants a change to the way Emacs works.

When you reply to a message please don't edit the quoted text as a

Emacs is doing what is asked for, as it should. Edit your .Xresources
file (usually located in your home directory) and remove or change the
color specifications for Emacs.
