I do not know why exactly I am so stubborn to insist on making this site multilingual, and in a way that you may see multiple languages at the same time. But it is something. 我自己也不明白为什么我执拗得一定要把这网站做成多语言的，还是叫人 能同时看到多种语言的那种。但聊胜于无吧。

A weird thing about HexoHexo 的诡异事件

The first weird thing I got, when I was trying to figure out hexo-theme-next: sometimes hexo server gives the perfect result, but when I hexo generate or hexo deploy, nothing will be correct. Everything is just malformed, and it does not change even if I hexo clean. 我在折腾 hexo-theme-next 的时候碰到的第一个诡异事件是： 有时候 hexo server 给出了个无懈可击的结果，但只要一 hexo generate 或者 hexo deploy，全完蛋。整个网站看着都非常诡异，甚至我 hexo clean 了之后也没有丝毫变化。

After digging a lot into the source code, and enabling --debug, I finally found that there are some backup files that are also processed. And the content of those files does correspond to the wrong contents on the site. "Okay," hereby I say, "this behaviour is indeed ridiculous." 钻进源码里东张西望了好久，再合着 --debug 的加成，我终于看到了一些备份文件 也被处理了。而其内容确然是应了网站上有问题的东西。「行吧，」如是我说， 「是事直令人齿冷。」

And thus I added the ignore rules to ignore all such files, and everything is hopefully back in place. 所以我加了忽略规则来忽略这种文件，世界终于清净了，谢天谢地。

NexT's language switcherNexT 的语言切换器

That is an even more terrible part that comes in. Yes, NexT comes with such a thing called a "language switcher," but it never takes you to a right place. I cannot even get Hexo generate pages for different languages, no matter how I change the language parameter in _config.yml. So whenever I click on the language switcher, I got a 404. And it is hidden at the very bottom of the page --- How should one expect their visitor to dig into the deepest hole before they can switch languages? 这玩意儿甚至更可怕了。是是是，NexT 有个叫「语言切换器」 的东西，但是它总把人引入歧途。让 Hexo 给不同的语言分别生成页面，这我 怎么改 _config.yml 里的 language 参数，也弄不成。所以呢，每次 按下这语言切换器的时候，404 就浮现在我眼前了。而且这切换器给藏在了页面 最底下——让访客钻进最深的洞里才许其切换语言，这能成吗？

So, well, since NexT's language switcher sucks, and multi-page style multi-language implementation is not feasible, why not just put everything all together? NexT at least provides a way to customize what texts are shown... in languages.yml. 啊啊，行吧，NexT 这语言切换器是糟透了，多页面显示多语言也办不到，那么把 所有东西全放一起，这又如何呢？NexT 至少给了个用 languages.yml 来控制 显示什么文字的方法呀......

The main idea is to merge NexT's default translations into one. I made a Perl script for this. The text for every language is a span, and they are next to each other. Use css to put a divider between every visible span. Whether a language is shown is controlled by a JavaScript program that adds or removes classes from the elements. 大意就是把 NexT 的默认翻译全整一起去。这事我写了个 Perl 脚本去做。每种语言的文字 装在一个 span 里，并并排。用 css 在每个显示了的 span 之间，摆一个分割线。 至于某种语言是显示呢是隐藏呢，这让 JavaScript 程序来控制，就从元素里加上或是减去 些 class 就好。

As I am too lazy, the code is all on GitLab. Whether this is a viable implementation is left as an exercise for the reader. 因为我太懒了，代码都在 GitLab 上。这东西到底可行不， 留给读者作练习。
