Apparently the correct way to set the default font is the following:

(custom-set-faces
 '(default ((t (:family "Raize" :foundry "raster" :slant normal
                :weight normal :height 120 :width normal)))))

But it's not portable, that means I cannot copy and paste on a different init.el on another computer if I don't check the existence of the correct font before.

A solution is to use a conditional. I already modified my emacs configuration to be environment sensitive, but I cannot solve this issue, I mean I did not manage how to correctly extract the statement from the (custom-set-faces ...) block to use within a (setq ...), for instance. Or, as alternative, I wonder if I can use an if() in this case.

Any clue?

Are you expecting to also use the Customize interface (UI)? If so then any top-level use of custom-set-faces in your init file (or custom-file) will be overwritten by Customize.

If you just want some code to do what you describe then something like this should do it:

(if XXXXXXXXX
    (custom-set-faces '(default ((t (:family "Raize" :foundry "raster" :slant normal
                                :weight normal :height 120 :width normal)))))
  (custom-set-faces '(default ((t YYYYYYYYYYYYYYYY)))))

But don't factor out the custom-set-faces and place it at top level in your init file, if you also use the Customize UI.

  • Well, using a form like if () custom-set () then custom-set () brings to a huge code duplication, doesn't it? – Daniele Oct 4 '17 at 16:03
  • You can factor out any parts that are duplicated, if you want. (You don't show the two face definitions...) Just don't put custom-set-faces at the top level in your init file, if you also use the Customize UI. – Drew Oct 4 '17 at 18:16

Thank you, at the end I preferred this solution:

(when (member "Raize" (font-family-list))
  (add-to-list 'initial-frame-alist '(font . "Raize"))
  (add-to-list 'default-frame-alist '(font . "Raize")))

in a secondary file. It's more compatible with my legacy configuration.
