我也被這個Smart Remove Selection震驚了

还是吐槽下编程吧:fortune cookie 以及中文 rot13

看完命令行的 fortune 程序源代码后真是毁童年

已经把 strfile 除了排序之外的功能重新用 C 语言实现得七七八八了,然而看到原实现那乱糟槽的代码,以及 strfile 的一个出于逻辑混乱的 bug,我已经不想完全复制功能了。按首字排序后的索引文件对 fortune 几乎一点用都没有,只对 unstr 有点意思,还要花时间读一大堆臭得要命的代码。unstr 仅仅是按索引顺序提取出索引文件的内容,简单过头,干嘛不将该功能合并到 strfile 呢。

还是自己重新设计 fortune 工具包吧。有 fortune cookie 数据就够了。
 


 

嗯,已经把实现放到 GitHub 上了,有什么编译问题希望能提出(最近很少來博客),毕竟我没在多个系统编译过。

其中稍微有点新意的是对中文,不,是对所有 Unicode 文本进行类似 rot13、剀撒变换的循环可逆文本混淆加密。

详细实现请看:https://github.com/jakwings/fortune.c/blob/v2/src/rotate.c

大概就是忽略空白和特殊字符,針對 UTF-8 code unit 進行分段式 rot13 加密,用简单工具测试过所有 Unicode 文本皆可顺利转换,且符合 UTF-8 编码。依然不排除在复杂情况下出现非法字符。
