recent emacs font problems?

recent emacs font problems?

[Miles Bader]

Has anyone noticed problems recently with changing emacs' default font?

I find that I can change the default font emacs uses with the `-font'
option, but changing from within emacs (either via `set-default-font' or
the S-mouse-1 menu) has no effect -- or rather, emacs continues to
_display_ characters using the old font, but apparently changes the
default character cell size to use the new font (e.g., the tab-width
gets changed, and the window gets resized -- since the characters are
still displayed in the old font, this means that both tabs and
window-size calculations are now wrong)!

I use the GTK toolkit.

I'm not entirely sure that this is an emacs problem (rather than an X
font problem, or a GTK problem), but other X/GTK apps seem OK, so
currently I'm assuming it's emacs.

Thanks,

-Miles

I can reproduce that bug without GTK toolkit too.

Same here (without GTK too).

Is this the right fix (not properly tested) ?

Hmm, that seems to fix things `sort of' -- it allows different fonts to
be set, and displayed but the font metrics are sometimes right,
sometimes wrong, e.g., using standard fonts, Courier10 - Courier18 look
correct, but Courier8 still has incorrectly sized tabs.  However this
may be a separate bug.

I can't provoke incorrectly sized tabs here.  But my setup is rather
vanilla.  Hm.

That is not correct.  It would bring back a bug I fixed recently.  I
think it was the following bug.


Date: Thu, 15 May 2003 09:59:01 +0200 (CEST)
From: Klaus Straubinger <KSNetz@Arcor.DE>
To: bug-gnu-emacs@gnu.org

If the font family of the default face is changed with
(set-face-attribute 'default nil :family "fixed")
then this does not change the face's font for subsequent frames, as can
be seen with the evaluation of (face-font 'default) in the first frame
and in a second, created with C-x 5 2, respectively.

I found that that call to set_lface_from_font_name was
clobbering the family that had come from the new-frame default.

Re: recent emacs font problems?

[Kim F. Storm]

Reading through the case and the comments, and comparing this to the
code, I'm uncertain whether the intention of the fix is to _only_
avoid overriding the :family property (that's not what the fix does,
but what the comment below says), or whether the intention really is
to avoid overriding any of the properties (as the fix does).

If the intention is only to avoid overriding :family, then we could
pass -1 for FORCE_P and test explicitly for force_p > 0 in
set_lface_from_font_name in connection with the :family property.

    but what the comment below says), or whether the intention really is

I think the old bug would have occured for any of the attributes that
are part of the font name.  But I did not test others, only :family.

I would guess that the attributes for which the new bug occurs are the
same ones for which the old bug, that was fixed by my change, used to
occur.  I suspect that the correct treatment is the same for all these
attributes.  But I don't know what is correct.  Someone needs to
figure out what happens in the case that fails now, why the change
caused this new bug, and how to distinguish the case in which we want
to forcibly set all the attributes there from the case in which we
don't.

Yes, things behave very strange.

I do not; my configuration options are:

    (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)

Sorry, I cannot help that much here.  Maybe, my setup is a little bit
strange (for historical reasons).  I set some X resources in
~/.Xresources and some others via lisp code.  Thus far I didn't find
the time to wirte down a proper bug report.

The problem is that if FORCE_P is 0, all other attributes of the font won't be 
set unless they are unspecified in the default face.  For exampel size.  So if 
you have a default face font which is fully specified (no undefined parts) no 
font change will happen.

I cant really grasp the problem that lead to this change from the comment 
above, so if anyone can describe a case for the original problem, I can try and 
make this work.

Here is what RMS said about the exact same fix some days ago; please

Thank you.  However, I still can't understand how things are supposed to
work.  In my .Xdefaults I set default font to courier-14.  Now if I
do (set-face-attribute 'default nil :family "fixed"), shall new frames
get courier-14 or fixed-14?  Currently they get fixed-14 but with the
font metrics of courier-14, so the frame is not 80 characters wide, but
more like 87 characters.

If I select courier 12 from the shift-down-1 menu, shall I get 
courier-12
or fixed-12?  Currently I get fixed-12 (with courier-12 font metrics).

    do (set-face-attribute 'default nil :family "fixed"), shall new frames

The set-face-attribute call should certainly override the X resource.
So the family must be "fixed".

      Currently they get fixed-14 but with the
    font metrics of courier-14,

I am not completely sure what that means.  Do you mean that Emacs
chooses the font fixed-14 but uses some data taken from the wrong
font?  That is clearly a bug.  Whichever font is chosen, Emacs
should use it consistently.

    If I select courier 12 from the shift-down-1 menu, shall I get 
    courier-12
    or fixed-12?  Currently I get fixed-12 (with courier-12 font metrics).

This should select courier 12, the font that you chose.

It means that when Emacs calculates pixel width and height of the new 
frame
it uses the width and height of courier-14, but then renders text with
fixed-14.  I think the default face for the new frame has not been 
realized
when this calculation occurs.

Re: recent emacs font problems?

[Jan D.]

Hello.

I have checked in a fix that solves the original problem.  I have only
tested under GNU/Linux and Mac OSX, so if anyone with access to MS
Windows could try it, we can see if it works there.  I don't use 
fontsets,
so I haven't tested that.

There is one bug I know of.  When making a new frame, the frame size is 
determined from the default font, not from the default face.  So if you
have a default font size 12, and default face with size 14, the frame
will be sized with the 12 size.  It seems to have been like this for a 
long
time (21.1 at least).  I know the root of the problem (default face
is realized after the frame is created), but not the fix yet.

indeed.

unfortunately, right now both win32 and rh9-gnu-linux builds fail with
the same error:

w32:

        "d:\gnu\emacs\src/obj-spd/i386/temacs.exe" -batch -l loadup dump
emacs: Invalid hash table rehash size: 0.0

linux:

...
emacs: Invalid hash table rehash size: 1.12341E-311

I do not have the linux error message in front of me, but the gist is
that the rehash size was not initialized.
linux sets the un-initialized double float with junk (that's where e-300
is coming from) while w32 sets it to 0.
but the bottom line is that the rehash size is un-initialized.

Do `rm *.o' in the build .../src directory before building.

[Thanks to Stefan for that!]

I'm not so sure.  I'm still seeing this crash:

The fix wasn't for a crash, this is a new bug. The fix was for the
fact that changes to the default font did not take effect.

    Here is what RMS said about the exact same fix some days ago; please
    read the previous articles in this thread for a discussion on this
    subject:

    RMS> That is not correct.  It would bring back a bug I fixed recently.  I
    RMS> think it was the following bug.

We need to understand what's going on in the two different cases
enough to figure out a way to distinguish them and do the right thing
for both.

Re: recent emacs font problems?

[Richard Stallman]

    The problem is that if FORCE_P is 0, all other attributes of the
    font won't be set unless they are unspecified in the default face.
    For exampel size.  So if you have a default face font which is
    fully specified (no undefined parts) no font change will happen.

That is right.

I made the change because in a specific circumstance it was wrong for
the defaults to be overridden here.  In some cases, you've found, it
is right for the defaults to be overridden here.

We need someone to figure out what distinguishes the case where they
should be overridden from the case where they should not be.
