杂谈 #Java脚本

因本人英语不好在使用Obsidian时，一些插件的设置英文多令人头痛。故有写一个的翻译插件介绍和设置脚本的想法。看到有些前人写的一下翻译方法，简直惨目忍睹。竟然要手动。这个应该写好到只需要一键就可以汉化的地步吗？
好吧。我承认这有些难度。翻译引擎就用有道的吧。我觉得它对专业名词的翻译准确度还是很高的。

1. 提取main.js中需要的词句
2. 使用有道API来翻译并生成对应的文件
3. 使用Quicker的插件一键替换

这里不想详细写过程了，直接贴代码吧。以后有空再整合。
main.js处理代码：（用了FastJson里面的工具，需要导入）

还有一个问题：
Quicker插件只是替换功能，有可能会替换到正文的单词。这里应该是需要再使用正则匹配一遍。干脆改成只用java来处理吧。
