Re: Macro Expansion Inconsistency

[Alexander Shukaev]

I currently have the following macro baked:

(defmacro bm-define-flag
    (name index character foreground)
  (let* ((symbol           (intern (format "bm-%s-flag"
                                           (symbol-name name))))
         (character-symbol (intern (format "%s-character"
                                           (symbol-name symbol)))))
    (put symbol 'index     index)
    (put symbol 'character character-symbol)
    (eval `(defcustom ,character-symbol
             ,character
             "Character for flag."
             :tag "BM Flag Character"
             :group 'buffer-manager
             :type 'character))
    (eval `(defface ,symbol
             `((t :foreground ,foreground
                  :weight     bold))
             "Face for flag."
             :tag "BM Flag Face"
             :group 'buffer-manager-faces))))

and running

(bm-define-flag xxx 777 ?$ "yellow")

gives the expected results, i.e. all the data structures are populated
properly. The only problem is that `defface' seems to be returning
`,symbol' itself (would be `bm-xxx-flag' in the above test case) and that
causes the error: (void-variable bm-xxx-flag) in `eval', i.e. in

eval(bm-xxx-flag nil)

How to overcome it? Do you have any further recommendations on this macro?

P.S. It's my first somewhat serious macro in Emacs Lisp ever, so I'd love
to learn more from pros until I do something dumb.
