Install font for emacs 24.x

Install font for emacs 24.x

[David AGBO]

Hi all,

I've installed emacs 24.3, and I would like to use a specific font 
(Meslo LG M DZ), but when I launch emacs, I have the message "Font 
`Meslo LG M DZ' is not defined". What is strange, is that when I 
downgrade emacs version from 24 to 23, using the same configuration 
file, I can use this font without any problem...

Here is how I declare Meslo in the configuration file :

-----
(setq default-frame-alist
   '(
     (width . 80)
     (tool-bar-lines . 0)
*=> (font . "Meslo LG M DZ") <=*
     (vertical-scroll-bars . nil)
     ))
(unless (fboundp 'prog-mode) (defalias 'prog-mode 'fundamental-mode))
...
-----

I've also tried Options->Set default font menu, but here again, there is 
a difference. Under emacs23, I have a little box to select the font, but 
under emacs24, I juste have a menu, where my font doesn't even appear.
Is there a directive to include at build time, or a new parameter in the 
configuration file, or anything else?

Best regards,
David

Is your font visible fc-list/fc-match, i.e., is it part of the libfontconfig based fonts service? Or is the X server providing the font? Is this function (by Miles Bader) showing your font? Is it showing a complete list of fonts? 


(defun list-fonts-display (&optional matching)
     "Display a list of font-families available via font-config, in a new buffer.
   If the optional argument MATCHING is non-nil, only font families
   matching that regexp are displayed; interactively, a prefix
   argument will prompt for the regexp.
   The name of each font family is displayed using that family, as
   well as in the default font (to handle the case where a font
   cannot be used to display its own name)."
     (interactive
      (list
       (and current-prefix-arg
	    (read-string "Display font families matching regexp: "))))
     (let (families)
       (with-temp-buffer
	 (shell-command "fc-list : family" t)
	 (goto-char (point-min))
	 (while (not (eobp))
	   (let ((fam (buffer-substring (line-beginning-position)
					(line-end-position))))
	     (when (or (null matching) (string-match matching fam))
	       (push fam families)))
	   (forward-line)))
       (setq families
	     (sort families
		   (lambda (x y) (string-lessp (downcase x) (downcase y)))))
       (let ((buf (get-buffer-create "*Font Families*")))
	 (with-current-buffer buf
	   (erase-buffer)
	   (dolist (family families)
	     ;; We need to pick one of the comma-separated names to
	     ;; actually use the font; choose the longest one because some
	     ;; fonts have ambiguous general names as well as specific
	     ;; ones.
	     (let ((family-name
		    (car (sort (split-string family ",")
			       (lambda (x y) (> (length x) (length y))))))
		   (nice-family (replace-regexp-in-string "," ", " family)))
	       (insert (concat (propertize nice-family
					   'face (list :family family-name))
			       " (" nice-family ")"))
	       (newline)))
	   (goto-char (point-min)))
	 (display-buffer buf))))

Thanks for your help Peter,

The font is visible with fc-list, I've installed it this way :

$> mkdir -p /usr/share/fonts/truetype/custom
$> wget 
"http://cloud.github.com/downloads/andreberg/Meslo-Font/Meslo%20LG%20DZ%20v1.0.zip" 

$> unzip Meslo\ LG\ DZ\ v1.0
$> mv Meslo\ LG\ DZ\ v1.0/*.ttf /usr/share/fonts/truetype/custom
$> fc-cache -f -v

I'll try the function and tell you.

Hi Peter,

As said, I've tried the function "list-fonts-display", and I can see my 
font in the list.
Is something missing, for the function to list the font and for emacs to 
not consider it?

Best regards,
David

Are you using the exact font name? Can you try with

	emacs -Q -fn 'that font name' &
	emacs -q -fn 'that font name' &
	emacs -fn 'that font name' &

For the latter test you *might* also like to disable the font settings in your init file.

Are you setting any X resources for GNU Emacs? (xrdb -q | grep -i emacs)

The 3 commands are returning my original error -> Font `Meslo LG M DZ' 
is not defined
but this is the exact font name also displayed by "list-fonts-display".

And I'm not using xrdb :

$> xrdb -q | grep -i emacs
bash: xrdb: command not found

Are you not using X11? Which variant of GNU Emacs are you using? M-x emacs-version RET should give a hint…

No, I'm not using X11 except for emacs, I'm working on a server in CLI.
What I get is : GNU Emacs 24.3.1 (i686-redhat-linux-gnu, GTK+ Version 
2.10.4) of 2013-03-11

When you're using GNU Emacs inside a terminal emulation in no-windows mode, then you need to convince the terminal emulation to use your font. (Because here GNU Emacs is slave [or, politically more correct, guest] of the terminal emulation and may not change anything.)
