Adams does not have a wiki. ;-) The code is on Emacs Wiki, at the regular
download location (Elisp Area):
https://www.emacswiki.org/emacs?action=elisp-area;context=0
Download frame-fns.el and frame-cmds.el, and load them in that order.
The function that uses (aref xlfd-fields xlfd-regexp-pixelsize-subnum) is
`frcmds-enlarged-font-name':
(defun frcmds-enlarged-font-name (fontname frame increment)
"FONTNAME, after enlarging font size of FRAME by INCREMENT.
FONTNAME is the font of FRAME."
(when (query-fontset fontname)
(let ((ascii (assq 'ascii (aref (fontset-info fontname frame) 2))))
(when ascii (setq fontname (nth 2 ascii)))))
(let ((xlfd-fields (x-decompose-font-name fontname)))
(unless xlfd-fields (error "Cannot decompose font name"))
(let ((new-size (+ (string-to-number (aref xlfd-fields
xlfd-regexp-pixelsize-subnum))
increment)))
(unless (> new-size 0) (signal 'font-too-small (list new-size)))
(aset xlfd-fields xlfd-regexp-pixelsize-subnum (number-to-string
new-size)))
;; Set point size & width to "*", so frame width will adjust to new font
size
(aset xlfd-fields xlfd-regexp-pointsize-subnum "*")
(aset xlfd-fields xlfd-regexp-avgwidth-subnum "*")
(x-compose-font-name xlfd-fields)))
