[EWW] 从其它浏览器导入书签

Emacs-general
1

EWW (Emacs Web Wowser) 也支持书签，我想把 Chrome 的书签导入。首先，从 Chrome 导出 书签文件 (HTML 格式) (其它浏览器应该一样)。然后，执行类似下面的命令，导入 EWW

(defun chunyang-eww-import-bookmarks (bookmarks-html-file)
  "Import bookmarks from BOOKMARKS-HTML-FILE."
  (interactive "fBookmarks HTML File: ")

  ;; Check if some libraries exist
  (require 'eww)
  (unless (require 'dom nil 'no-error)
    (user-error "dom.el not available, it was added in Emacs 25.1"))
  (unless (fboundp 'libxml-parse-html-region)
    (user-error "`libxml-parse-html-region' not available, \
your Emacs doesn't have libxml2 support"))

  (with-temp-buffer
    (insert-file-contents bookmarks-html-file)
    (setq eww-bookmarks
          (loop with dom = (libxml-parse-html-region (point-min) (point-max))
                for a in (dom-by-tag dom 'a)
                for url = (dom-attr a 'href)
                for title = (dom-text a)
                for time = (current-time-string
                            (seconds-to-time
                             (string-to-number
                              (dom-attr a 'add_date))))
                collect (list :url url
                              :title title
                              :time time)))
    (eww-write-bookmarks))

注意上面的代码：

  • 需要 Emacs 25.1+，因为用到了 25.1 新加入的 dom.el 来搜索查找 DOM；
  • 不会处理 Chrome 书签中的文件夹，因为 EWW 的书签不支持用文件夹管理书签；
  • 会覆盖原来的 EWW 书签。

刚试了一下EWW，比w3m快了不止一个数量级啊（在我的电脑上是这样）

但是网上它的教程好少啊

楼主有没有好的配置提供一份啊？

EWW 开箱即用吧，用不着任何配置。

我的配置里面有关于书签、搜索引擎、代码高亮、字体、亮度这几个方面，都是蛮私人的设定，对别人有没有帮助就不得而知了。

eww能登录论坛吗？ 它与w3m比，有什么限制啊？ 感觉它没有多少快捷键呢

5

不能（你自己试下就知道了）。EWW 不支持 JavaScript，登录的话需要用到 JavaScript。

没用过 w3m，不了解它

6

嗯，我觉得EWW挺好用的。

知道怎么设置它的代理吗？

网上的方法都是全局代理啊，怎么写一个toggle啊？需要的时候再开启代理。

7

关于 url.el 代理的讨论：

@zilongshanren 在 21 天学会 Emacs 之第 19 天：Elisp 技巧 的末尾给了一个 Toggle 的命令，我自己写过一个类似的，但是我发现代理并不会及时地得到修改，我不清楚什么原因，你有这个需求地话，可以自己研究看看。另外，url-gateway-local-host-regexp 可以设置白名单。

有白名单的话就不用toggle了，我试试，谢谢。
