编辑部专版 - Brainfuck 和他的朋友们

前些天在上网冲浪的时候看到了一门叫做 Brainfuck 的编程语言，秉承着了解一门编程语言就先学会它的 Hello,World 的原则，我搜索到了 Brainfuck 的 Hello World 源代码:

brainfuck

>+++++++++[<++++++++>-]<.>++++++[<+++++>-]<++++.+++++++..+++.>>>+++++[<+++++>-]<<.>>>++++++++[<+++++++++>-]<---.<<<<.+++.------.---------.>+.

这 TM 是编程语言?

Brainfuck

Brainfuck 是一门简单的深奥语言，具有图灵完备性，它仅用了八个字符来作为指令。Brainfuck 基于一个字节数组（内存带）和指针操作，指令如下：

字符	作用
>	指针右移
<	指针左移
+	当前指针指向的字节值加 1
-	当前指针指向的字节值减 1
.	输出当前字节（ASCII 字符）
,	输入一个字节到当前指针位置
[	若当前字节为 0，跳转到匹配的 ]
]	若当前字节非 0，跳回匹配的 [

那么，之前提到的代码就好解释了，比如代码片段

brainfuck

>+++++++++[<++++++++>-]<.

+++++++++：指针右移，当前单元格存储 9（作为循环计数器）。
[<++++++++>-]：循环 9 次，每次左移指针并加 8（9×8=72，即 'H' 的 ASCII 值）。
<.：指针左移并输出当前单元格的值（72 → H）。

其他的片段也同理，太麻烦了不做解释，如果你想要体验这门深奥编程语言，可以下载这个 C 语言写的Brainfuck 解释器

在看到了这个语言之后，我又找到了其他的奇怪的编程语言

Ook

我建议各位用小米设备并循环播放 Are you OK 来使用这个语言。这东西就是 Brainfuck 的一个变种，区别就是用八种不同语气的 Ook 来替换 Brainfuck 的八个指令。

Ook! 指令	Brainfuck 指令	作用
Ook. Ook?	>	指针右移
Ook? Ook.	<	指针左移
Ook. Ook.	+	当前单元格值加 1
Ook! Ook!	-	当前单元格值减 1
Ook! Ook.	.	输出当前字符（ASCII）
Ook. Ook!	,	输入字符到当前单元格
Ook! Ook?	[	循环开始（若当前值为 0 则跳转）
Ook? Ook!	]	循环结束（若当前值非 0 则跳回）

我觉得按照这个思路，我一天能创造八门语言，比如说Kitten No.1语言

Kitten No.1 指令	Brainfuck 指令	作用
Kitten No.1. Kitten No.1?	>	指针右移
Kitten No.1? Kitten No.1.	<	指针左移
Kitten No.1. Kitten No.1.	+	当前单元格值加 1
Kitten No.1! Kitten No.1!	-	当前单元格值减 1
Kitten No.1! Kitten No.1.	.	输出当前字符（ASCII）
Kitten No.1. Kitten No.1!	,	输入字符到当前单元格
Kitten No.1! Kitten No.1?	[	循环开始（若当前值为 0 则跳转）
Kitten No.1? Kitten No.1!	]	循环结束（若当前值非 0 则跳回）

Piet

看下面这幅图片： Piet 是一种基于颜色代码的深奥编程语言，由 David Morgan-Mar 设计。其程序以抽象艺术风格的位图图像呈现，通过指针在连续色块区域间的移动实现指令执行与编译过程

这是画作吗？不，这是一门叫做 Piet 的编程语言的代码。该语言使用包含 20 种颜色的调色板，其中 18 种颜色按 6 种色相（红、黄、绿、青、蓝、紫）和 3 级亮度（明、常、暗）构成循环系统。指令由色相与亮度的变化差值决定，数据通过堆栈结构存储。执行时通过方向指针(DP)和色块选择器(CC)控制流程，黑色区域触发转向判定直至程序终止。由于编译器不好找，我们在这里贴几张 Piet 语言的程序

这是一个 Hello World 这是一个加法器这是一个 cowsay 程序的 Piet 实现

JSFuck

严格意义上来说这并不是一个编程语言，而是 Javascript 的一种形式，可以把 JavaScript 转换成由六个字符组成的的神似 BrainFuck 的 JavaScript 代码，并且可以运行。例如，这是 JavaScript 的 Hello World 代码:

javascript

console.log("Hello World");

这是被 JSFuck 给 Fuck 之后的 JS：

关键是他真的能运行。但是，这东西并不能用来混淆你的网站的 JS 代码，它是可以还原成正经的 JS 的，并且会影响 JS 的执行效率。想要体验一下的同学可以用这条指令使用 npm 全局安装 JSFuck 转换器:

bash

$ npm i jsfuck --global

或者访问JSFuck 编码器这个网站把你的 JS 给 Fuck 掉
