I In general, emacs questions (even emacs lisp) would be better answered in one of the emacs newsgroups, such as news:gnu.emacs.help. However, this one is not specific to emacs, so we'll answer here: > tried something like this: > > ;; f-name and f-size-default are strings set to something > ;; reasonable > (setq my-default-font (concat f-name f-size-default)) > (add-to-list 'default-frame-alist '(font . my-default-font)) > > then when I start emacs I get logs like this > > frame-notice-user-settings: Invalid font: my-default-font > > It seems to be a lisp thing that I cannot grasp. Why is that the value > of my-default-font is not replaced in the last expression? What does the quote do? What does 'x evaluate to? And what does '(a b c) evaluate to? And what does '(a . b) evaluate to? So what does '(font . my-default-font) evaluate to? What other mean to create a cons cell do you know? -- __Pascal Bourguignon__
