The following is a lump of code I use to fontify source code on my site, http://rtfm.etla.org/ (which was the reason, incidentally, that Htmlfontify was written in the first place).
(defvar rtfm-section nil)
;; Constructs an appropriate header string to fit in with rtfm's
;; templating system, based on the file and the stylesheet string
(defun rtfm-build-page-header (file style)
(format "#define TEMPLATE red+black.html
#define DEBUG 1
#include <build/menu-dirlist|>\n
html-css-url := /css/red+black.css
title := rtfm.etla.org ( %s / src/%s )
bodytag :=
head <=STYLESHEET;\n
%s
STYLESHEET
main-title := rtfm / %s / src/%s\n
main-content <=MAIN_CONTENT;\n" rtfm-section file style rtfm-section file))
;; the footer:
(defun rtfm-build-page-footer (file) "\nMAIN_CONTENT\n")
(defun rtfm-fontify-buffer (section)
(interactive "s section[eg- emacs / p4-blame]: ")
(require 'htmlfontify)
(let ((hfy-page-header 'rtfm-build-page-header)
(hfy-page-footer 'rtfm-build-page-footer)
(rtfm-section section))
(htmlfontify-buffer)
)
)
;; Here's the function I actually call---it asks me for a section label,
;; and source and destination directories, and then binds a couple of
;; customization variable in a let before calling htmlfontify:
(defun rtfm-build-source-docs (section srcdir destdir)
(interactive
"s section[eg- emacs / p4-blame]:\nD source-dir: \nD output-dir: ")
(require 'htmlfontify)
(hfy-load-tags-cache srcdir)
(let ((hfy-page-header 'rtfm-build-page-header)
(hfy-page-footer 'rtfm-build-page-footer)
(rtfm-section section)
(hfy-index-file "index")
(auto-mode-alist (append auto-mode-alist
'(("dbi\\(shell\\|gtk\\)$" . cperl-mode)
("\\.xpm$" . c-mode ))))
)
(htmlfontify-run-etags srcdir)
(htmlfontify-copy-and-link-dir srcdir destdir ".src" ".html")))
