Default mm-uu-extract face hard to read on ttys

Default mm-uu-extract face hard to read on ttys

[Sascha Wilde]

Hi *,

The default mm-uu-extract face is hard to read on ttys, as it defaults
to light yellow on dark green, which gets translated to white on
(bright) green on 8 color tty.

It is used for highlighting text in messages which is marked a verbatim:

--8<---------------cut here---------------start------------->8---
this is an example
--8<---------------cut here---------------end--------------->8---

Could you suggest change to the face definition?  (IIRC Emacs 21
doesn't support `min-colors').

(defface mm-uu-extract '(;; Colors from `gnus-cite-3' plus background:
			 (((class color)
			   (background dark))
			  (:foreground "light yellow"
			   :background "dark green"))
			 (((class color)

  "Face for extracted buffers."

While I don't see why we should bother about the features of Emacs 21
for changes in 22/23 I think that testing for tty should be sufficient.

How about something along the lines of:

(defface mm-uu-extract '(;; Colors from `gnus-cite-3' plus background:
			 (((type tty)
			   (class color)
			   (background dark))
			  (:foreground "white"
			   :background "dark blue"))

			  (:foreground "dark blue"

			  (:foreground "light yellow"
			   :background "dark green"))
			 (((class color)
			   (background light))
			  (:foreground "dark green"
			   :background "light yellow"))			 
			 (t
			  ()))
  "Face for extracted buffers."

Of course you can.  One has to enter history, whatever the door :)

Because No Gnus (aka Gnus 5.13) is supposed to run on Emacs >= 21.
See (info "(gnus)Emacsen").

I've installed a similar change (in Gnus CVS; will be synced to Emacs
later).  Is this color okay?

(defface mm-uu-extract '(;; Inspired by `gnus-cite-3'

Gnus problem with nil font in face definition (was: Default mm-uu-extract face hard to read on ttys)

[Ted Zlatanov]

With the latest Emacs from CVS and the latest Gnus from CVS, many Gnus
faces look strange.  They were fine with checkouts from about a month
ago.

It seems that the cause is faces that have the font set to nil, instead
of unspecified.  I don't know if this is a Gnus-only problem, and it may
be caused by an Emacs problem, so I am cc-ing both emacs-devel and ding.

For example, describe-face on message-header-to says:

Face: message-header-to (sample) (customize this face)
Documentation: Face used for displaying From headers.
Defined in `message.el'.

        Family: unspecified
         Width: unspecified
        Height: unspecified
        Weight: bold
         Slant: unspecified
    Foreground: DarkOliveGreen1
    Background: unspecified
     Underline: unspecified
      Overline: unspecified
Strike-through: unspecified
           Box: unspecified
       Inverse: unspecified
       Stipple: unspecified
          Font: nil
       Fontset: unspecified
       Inherit: unspecified

but message-header-name is:

Face: message-header-name (sample) (customize this face)
Documentation: Face used for displaying header names.
Defined in `message.el'.

        Family: unspecified
         Width: unspecified
        Height: unspecified
        Weight: unspecified
         Slant: unspecified
    Foreground: green
    Background: unspecified
     Underline: unspecified
      Overline: unspecified
Strike-through: unspecified
           Box: unspecified
       Inverse: unspecified
       Stipple: unspecified
          Font: unspecified
       Fontset: unspecified
       Inherit: unspecified

For me, message-header-name appears normal, using the right font from
my X defaults:

#define FONT_ISO_XL -misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1
Emacs*font: FONT_ISO_XL

but message-header-to is set in a large proportional font, which looks
ugly.  describe-font crashed my Emacs session, so I'm not sure about the
specifics of the font that was used.

If you can reproduce this, please report it via M-x report-emacs-bug.

I saw it twice this morning and then I couldn't reproduce it again
inside GDB or outside it.  Very strange.

I'm quite sure that nothing in Gnus/Message has changed in this area,
so it is probably related to the unicode merge (new font back end?)

For those not using Gnus, a test case might be:

- emacs -Q -fn '-misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1'

- Type:
  To: foo@bar.invalid

- M-x message-mode RET

Clean up:
- C-x k yes RET
- rmdir ~/Mail/drafts/    (if it has been created)

I tested this and it also shows the wrong font, so it's definitely not a
Gnus issue.

When I tested this earlier I looked at a cperl-mode buffer and it didn't
look like it was using the proportional font.  I checked again now and I
had simply not scrolled down enough to see a face that was affected by
this bug.

I found what is wrong with the current font-backend code.

% xlsfonts -fn -misc-fixed-*-*-*--20-200-75-75-c-100-iso10646-1

lists these fonts.

-misc-fixed-bold-r-normal--20-200-75-75-c-100-iso10646-1
-misc-fixed-bold-r-normal--20-200-75-75-c-100-iso10646-1
-misc-fixed-bold-r-semicondensed--20-200-75-75-c-100-iso10646-1
-misc-fixed-medium-o-normal--20-200-75-75-c-100-iso10646-1
-misc-fixed-medium-o-semicondensed--20-200-75-75-c-100-iso10646-1
-misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1
-misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1
-misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1
-misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1
-misc-fixed-medium-r-semicondensed--20-200-75-75-c-100-iso10646-1

but the result of

% xlsfonts -fn -misc-fixed-*-*-*--*-*-*-*-c-*-iso10646-1

doesn't contain this font:
-misc-fixed-bold-r-normal--20-200-75-75-c-100-iso10646-1

I'm now working on handling such a case correctly.
By the way, if you specify this font (i.e. a font whose bold
versoin also exists without auto-scaling):

-misc-fixed-medium-r-normal--18-120-100-100-c-90-iso10646-1

Emacs can find the correct bold version (at least in my
environment).

Was my guess correct that a nil font in the face specification is the
problem?  Or is it specifically a problem with the font I use, as I
think you're saying?  Or both?

Hello again,

any progress with this problem?  I would really prefer not to use the
medium version of this font, as it's unpleasantly thin.

I'm now working on the overhaul of font related code
(completely shifting to font-backend), but it takes more
time.
