I want to use the same configuration for both Ubuntu and Windows, so I want to share my ~/.emacs between boxes. I'd like, however, to use the Consolas font in Windows, and Ubuntu Mono font in Ubuntu.

How can I autodetect which OS emacs is running in, and define the font code conditionally on the environment?

You can check the system-type and use set-frame-font accordingly.

Here is a short example:

(setq my-prefered-font
      (cond ((eq system-type 'windows-nt) "consolas")
            ((eq system-type 'gnu/linux) "mono")
            (t nil)))

(when my-prefered-font
  (set-frame-font my-prefered-font nil t))

Note, that you can also set font size. For example I do (setq my-prefered-font "Hack-10").

Hint: I found list-fontsets useful to list available fonts.

And one last note, I do the following to set system specific configurations in my init.el:

(load-file (expand-file-name
            (cond ((eq system-type 'windows-nt) "windows.el")
                  ((eq system-type 'gnu/linux) "linux.el")
                  (t "default-system.el"))
            user-emacs-directory))

with windows.el, linux.eland default-system.el in folder ~\.emacs.d with all the system specific stuff.

  • I really like your last suggestion, but it comes back with the following error: Symbol's function definition is void: load-with-warning. Maybe you defined this function? Is there a vanilla way of doing this, without custom functions? – philsf Aug 23 '16 at 12:54

    @philsf You are right, I defined load-with-warning. I edited my answer accordingly to avoid the function. – theldoria Aug 23 '16 at 14:38
  • Thanks. I was trying to fix it unsuccesfully, but now I see what I was doing wrong. – philsf Aug 23 '16 at 14:55
