org-capture 手机浏览器页面

Org-mode

以把 capture 手机浏览器页面为例。在手机上利用 bookmarklet 把当前页面的标题和 URL，发送到 org-capture。

假设用这样一个 org-capture 模版保存链接：

(add-to-list
 'org-capture-templates
 '("l" "Link" entry (file "links.org")
   "* %a"))

开启一个 HTTP 服务器，当有人访问 http://localhost:3000/?url=...&title=... 时，自动调用上面的 org-capture 模版：

(defun chunyang-org-capture-server (request)
  (pcase-let (((eieio process headers) request))
    (message "%S" headers)
    (let ((path (assoc-default :GET headers)))
      ;; 只处理 GET /
      (if (not (and path (string= path "/")))
          (ws-send-404 process)
        (let ((href (assoc-default "href" headers))
              (title (assoc-default "title" headers)))
          (setq title (decode-coding-string title 'utf-8))
          (push (list href title) org-stored-links)
          ;; XXX 不确定这对不对
          (org-link-store-props :type "http"
			        :link href
			        :description title
			        :annotation (org-link-make-string href title))
          (let ((org-capture-link-is-already-stored t))
            (org-capture nil "l"))
          (let ((body "Successfully sent to Org Capture"))
            (ws-response-header
             process 200
             (cons "Content-Type" "text/plain")
             (cons "Content-Length" (string-bytes body)))
            (ws-send process body)))))))

(ws-start #'chunyang-org-capture-server 3000)

然后在手机上建立 bookmarklet，类似以下（1、要把 *.xyz 网址改成你的，不然可能会发送到我的 Emacs 里；2、应该把 URLSearchParams 改成 encodeURIComponent，我刚刚发现前者有问题）

javascript:location.href = "https://frp.cadr.xyz/?" + \
  new URLSearchParams({"href": location.href, "title": document.title})
