注 ：这是我在写 moz-controller 时的记录，因为是写给自己看的，所以思维比较跳跃，文字也没有雕琢，只是希望能为 Emacs Lisp 爱好者提供一些参考价值。
A few days ago, for no reason (for fun, maybe), I cloned the Github mirror of Emacs and built a latest Emacs. I also removed my old Emacs (I was silly, I blame Melbourne’s weather :D). Many subtle problems occurred since then, for example, executing org-html-export-as-html often causes the following error:
org-html-fontify-code: Wrong number of arguments: #[(_beg _end) "À ‡" [font-lock-fontify-buffer] 1], 0
I’ve added a new functionality to emacs-moz-controller: with some simple configurations, you can press C-c m u in Emacs to view the source of the current Firefox page.
前几天心血来潮，克隆了 Emacs 的 Github 镜像，自己编译了一个最新的 Emacs。而且非常无脑地把原来的 Emacs 删掉了。自此，各种小问题层出不穷，比如 org-html-export-as-html 时，经常会出现：
org-html-fontify-code: Wrong number of arguments: #[(_beg _end) "À ‡" [font-lock-fontify-buffer] 1], 0
给 emacs-moz-controller 新添加了个功能: 简单配置一下 Firefox 之后, 在 Emacs 中按 C-c m u 来查看当前页面的源代码.
Note: This blog is the README of moz-controller, which is the first Emacs plugin I’ve ever written. Github: https://github.com/RenWenshan/emacs-moz-controller.
注: 本文是 moz-controller 的中文 README (commit 7e3d05f). moz-controller 是我写的第一个 Emacs 插件, github 地址: https://github.com/RenWenshan/emacs-moz-controller.
It’s very common for me to program while read documents in a web browser, and I think it’s annoying to switch between the browser and the text editor constantly.
Here I have a few Elisp functions defined, which allow me to control Firefox to scroll, close tabs and so on.
