Non-default fonts in Emacs using Xft

Non-default fonts in Emacs using Xft

[Felix Eckhofer]

Hi.

I've been playing a little with Emacs from the unicode-2 branch.
However I cannot get it to render non-default-sized fonts with
antialiasing, for examples headlines in auctex show up like this:
http://secundus.stunet.tu-freiberg.de/~felix/temp/screenshots/emacs-xft.png

Is there some sort of "global font parameter" I have not found? I tried
set-default-font and set-fontset-font as suggest on emacswiki.org but
nothing seems to help.

Thanks for any advice.


best regards
felix

Are you sure that your GNU Emacs 23 was configured and compiled to  
achieve font anti-aliasing? (Trying to report a bug you can retrieve  
some information on this.)

I think there is none, except: on the command line you need to add -- 
enable-font-backend. You also need to prepare your system with  
fontconfig. It uses (an) XML file(s) to mention all directories with  
fonts, name substitutes, define standards ... When I try to launch  
GNU Emacs 23 with activated font backend I get an error – I think  
it's really time for a bug report!


BTW, you don't need to write your LaTeX documents in UTF-8 using  
LaTeX's incomplete UTF-8 support. ISO 8859-9 would be sufficient:

	%% -*- mode: LaTeX; coding: iso-8859-15; -*-	either this header line  
or the Local Variables section at the end
	\usepackage{ifpdf}
	\ifpdf
	   \immediate\write16{\jobname: Bonjour, PDF!}
	   \usepackage{cmap}
	   \usepackage[pdftex]{graphicx}
	%   \DeclareGraphicsExtensions{.png,.gif,.tif,.jpeg}	% what  
about .svg ?
	   \usepackage[activate={true,nocompatibility}]{microtype}
	\else		% for non-pdfTeX
	   \immediate\write16{¡Hola \jobname: DVI!}
	%   \DeclareGraphicsExtensions{.eps,.ps}
	   \usepackage[dvips]{graphicx}
	   \usepackage[protrusion=true,expansion=false]{microtype}
	\fi
	\usepackage[ngerman]{babel}
	%\usepackage{lmodern}
	\usepackage[T1]{fontenc}
	\usepackage[full]{textcomp}
	\usepackage[latin9]{inputenc}
	
	
	%%% Local Variables:
	%%% mode: LaTeX

Yes, I am (--with-xft --enable-font-backend). Also, antialiasing seems
to work for everything *except* the non-default font (e.g.
AucTeX-headlines) - see screenshot.

According to the docs this parameter is deprecated. Font-backend is now
enabled by default and can be disabled using --disable-font-backend.

I don't think this is the issue. fc-list shows 283 fonts and no other
application seems to have any problems.

Yes, I can vouch that this is the case.  But how do you specify the
font?  If you have not done so yet, try adding a line like this:

Emacs.font: DejaVu Sans Mono-10

To your .Xresources file, running "xrdb ~/.Xresources" from the
command-line, and restarting Emacs.

AUCTeX works for me as you would like, and I've not set any variables in
my .emacs especially to achieve this.

Thanks. I tried that already however this also seems to only change
the "default" font, not headlines and such.
I wonder if this might be an X11 configuration problem. Currently I'm
using default Ubuntu Feisty font-paths.
However, there really should be an option allowing me to globally change
the default font-face.

That's the desired behaviour: did you ever see some TeX output with  
headers in the same style as the text, all serifs or all sans serifs?

If you want to change the look in GNU Emacs you can customise AUCTeX  
– it has a great menu for this!

That was not quite what I meant. However, I finally found the solution
by clicking through a lot of "customize" pages:

(set-default-font "DejaVu Sans Mono-10")
(custom-set-faces
 '(fixed-pitch ((t (:family "DejaVu Sans Mono"))))
 '(variable-pitch ((t (:family "DejaVu Sans")))))

Now my emacs looks great - the way emacs should look in 2007 :-)
