26 March 2015 Helm buffer URLs

Venturing into Emacs lisp and Helm. Here's a go at listing all URLs in current buffer.

(require 'goto-addr)

(defun ar/helm-buffer-url-candidates ()
  "Generate helm candidates for all URLs in buffer."
    (goto-char (point-min))
    (let ((helm-candidates '())
      (while (re-search-forward goto-address-url-regexp
                                nil t)
        (setq url
              (buffer-substring-no-properties (match-beginning 0)
                                              (match-end 0)))
        (add-to-list 'helm-candidates
                     (cons url

(defun ar/helm-buffer-urls ()
  "Narrow down and open a URL in buffer."
  (helm :sources `(((name . "Buffer URLs")
                    (candidates . ,(ar/helm-buffer-url-candidates))
                    (action . (lambda (url)
                                (browse-url url)))))))
