如何让newsticker处理一些图片链接有问题的feed？

Emacs-general

例如我目前有些feeds里面图片连接是这种写法，导致newsticker渲染不出

<img
src="//cdn.journals.aps.org/journals/PRL/key_images/10.1103/PhysRevLett.133.141801.png" width="200" height=\"100\"><br/>

似乎是缺少了https:，但是应该修改哪个shr.el里面的函数呢 ？

改 shr-expand-url，加个 :before advice 改写 url 参数。

感谢，顺便贴下解决方案：

(defun shr-broken-url (url &optional base)
  (let* ((url-data (url-generic-parse-url (car url)))
         (url-base (url-filename url-data))
         (url-host (url-host url-data))
         (url-port (url-portspec url-data))
         (url-target (url-target url-data))
         (url-header (url-type url-data)))
    (unless url-header (setq url-header "https"))
    (when url-header (setq url-header (concat url-header "://")))
    (when url-port (setq url-port (concat  ":" url-port)))
    (when url-target (setq url-port (concat  "#" url-port)))
    (list (concat url-header url-host url-port url-base url-target) base)))

(advice-add 'shr-expand-url :filter-args 'shr-broken-url)
