Hi Christian,
The following would make the exported HTML link to an external stylesheet.
#+STYLE:<link rel="stylesheet" type="text/css" href="my_style.css"/>
But that 's not what you're after? You want the stylesheet to be /outside/
(linked from) your Org file, but /embedded in/ the exported HTML? Did I get
that right?
Indeed. That would be the ideal solution for me: it would bring all the
advantages I'm looking for:
- separate files for developing separately the style and the content;
- anybody could export the file as no special Emacs configuration is needed;
- the exported file would be self-contained.
Do you think about one way of doing this?
Something roughly along these lines, perhaps (warning: I'm still
fairly new to Elisp and this comes with ABSOLUTELY NO WARRANTY):
#+BEGIN_SRC emacs-lisp
(defun cm/org-export-html-embed-style ()
(make-local-variable 'org-export-html-style)
(setq org-export-html-style "")
(let ((re "#\\+STYLE:\\s +<link\\s +rel=[\"']stylesheet[\"']\\s
+type=[\"']text/css[\"']\\s +href=[\"']\\(.*\\)[\"']/>")
(oldbuf (current-buffer))
stylesheet
css)
(goto-char (point-min))
(while (re-search-forward re (point-max) t)
(setq stylesheet (match-string 1))
(with-current-buffer (find-file stylesheet)
(setq css (format "\n<style>\n%s\n</style>\n"
(buffer-string))))
(setq org-export-html-style (concat org-export-html-style
css)))
(switch-to-buffer oldbuf)))
(org-add-hook 'org-export-first-hook 'cm/org-export-html-embed-style)
#+END_SRC
Usage: Link to one or more external stylesheets from your Org file.
: #+STYLE: <link rel='stylesheet' type='text/css' href='test5.css'/>
The contents of the stylesheet(s) will be embedded in the exported
HTML between <style> tags.
The function swaps the ontent of the external stylesheets into
org-export-html-style. If you're already using that variable, the
above might screw things up. I'd prefer to use
org-export-html-style-extra, but for some reason that didn't work..
This function doesn't remove the links to the external stylesheets,
because it operates on the original document, not on a copy. You could
add an org-export-preprocess-hook to remove the links, reusing the
regexp from this example. (Running the above function as an
org-export-preprocess-hook does not work.)
Hope this helps,
CM
