Hello all,
I want to define a capture template which pre-processes the head of the kill
ring with a sexp that takes a string as an argument:
(setq org-capture-templates
(quote
(("l" "Link" entry (file+headline "" "Links")
"* \"%c\" %(get-page-title \"%c\")"))))
;; throws Bad url
(get-page-title "foo-bar")
;; works as expected
(get-page-title "http://orgmode.org/manual/Template-expansion.html")
(defun get-page-title (url)
"Get title of web page, whose url can be found in the current line"
;; Get title of web page, with the help of functions in url.el
(with-current-buffer (url-retrieve-synchronously url)
;; find title by grep the html code
(goto-char 0)
(re-search-forward "
\\([^<]*\\)" nil t 1)
(setq web_title_str (match-string 1))
;; find charset by grep the html code
(goto-char 0)
;; find the charset, assume utf-8 otherwise
(if (re-search-forward "charset=\\([-0-9a-zA-Z]*\\)" nil t 1)
(setq coding_charset (downcase (match-string 1)))
(setq coding_charset "utf-8")
;; decode the string of title.
(setq web_title_str (decode-coding-string web_title_str (intern
coding_charset)))
)
(concat "[[" url "][" web_title_str "]]")
))
Please just ignore that I'm trying to parse XML with a regexp here.
get-page-title works when called from code but always returns bad url when
called from the capture template.
Is the problem the way I escape the string or is this just not the way the
sexp in capture are supposed to be used?
Regards,
Philipp
