解读DOGO

DOGO是鲜为人知的编程语言。最初的DOGO（Usenet帖子中的玩笑语言）从未实现，但已经创建了类似的语言。该语言的命令为：

+===========+================================================================+
|  Command  |                          Description                           |
+===========+================================================================+
| SIT       | If the value of the current memory cell is 0, jump to STAY.    |
+-----------+----------------------------------------------------------------+
| STAY      | If the value of the current memory cell is not 0, jump to SIT. |
+-----------+----------------------------------------------------------------+
| ROLL-OVER | Select the next operation from the operation list.             |
+-----------+----------------------------------------------------------------+
| HEEL      | Execute the currently selected operation.                      |
+-----------+----------------------------------------------------------------+

操作是：

+========+=======================================================+====+
| Number |                      Description                      | BF |
+========+=======================================================+====+
|      0 | Increment current memory cell.                        | +  |
+--------+-------------------------------------------------------+----+
|      1 | Decrement current memory cell.                        | -  |
+--------+-------------------------------------------------------+----+
|      2 | Move to next memory cell.                             | >  |
+--------+-------------------------------------------------------+----+
|      3 | Move to previous memory cell.                         | <  |
+--------+-------------------------------------------------------+----+
|      4 | Input a byte and store it in the current memory cell. | ,  |
+--------+-------------------------------------------------------+----+
|      5 | Output the current memory cell as ASCII.              | .  |
+--------+-------------------------------------------------------+----+

规则

• 每个提交应该是完整的程序或功能。如果它是一个函数，则只需将函数调用添加到程序底部即可使其可运行。其他任何内容（例如C中的标头）都必须包括在内。
• 如果可能，请提供一个可以测试您的代码的在线站点的链接。
• 您的程序无法写入任何内容STDERR（或类似内容）。
• 您可以从STDIN（或使用您语言中最接近的替代语言）输入，也可以作为参数。
• 禁止出现标准漏洞。

计分

程序根据字节计分。默认字符集为UTF-8，如果使用其他字符集，请指定。

除此之外，这是 代码高尔夫球，最低字节数将被视为获胜者！

意见书

为确保您的答案显示出来，请使用以下Markdown模板以标题开头。

# Language Name, N bytes

N您提交的文件大小在哪里。如果您提高了分数，则可以通过打败旧分数来保持标题。例如：

# Ruby, <s>104</s> <s>101</s> 96 bytes

如果要在标头中包含多个数字（例如，因为您的分数是两个文件的总和，或者您想单独列出解释器标志罚分），请确保实际分数是标头中的最后一个数字：

# Perl, 43 + 2 (-p flag) = 45 bytes

您还可以将语言名称设置为链接，然后该链接将显示在页首横幅代码段中：

# [><>](http://esolangs.org/wiki/Fish), 121 bytes

更新：

抱歉，无法很好地阐明sitand stay命令。正如@ user6245072所说，它们[与]BF中的一样。

更新2：

为了澄清@KennyLau的问题：

• 默认操作是0。
• 存储器由8位单元组成。
• 单元会在上溢/下溢时自动换行。
• 操作4需要输入。

Ruby，287个字节

在两个方向上在无限的磁带上运行。DOGO输入是命令行上的文件。如果没有命令行参数，则DOGO程序如果作为STDIN传入，则仍然可以工作，除非它使用操作3（从STDIN获取字节），在这种情况下我不知道。无论如何，文件输入是最好的。

假定程序文件中除了四个命令和空格外没有其他文本。

你好世界示范

i=k=o=0;m={}
c=$<.read.upcase.split.map{|e|%w{SIT STAY ROLL-OVER HEEL}.index e}.join
(m[k]||=0
e=c[i].to_i
e>2?o>4?$><<m[k].chr:
o>3?m[k]=STDIN.getc.ord:
o>1?k+=o>2?-1:1:
m[k]=o<1?-~m[k]%256:~-m[k]%256:
e>1?o=-~o%6:
e>0?m[k]>0?i=c.rindex(?0,i):0:
m[k]<1?i=c.index(?1,i):0
i+=1)while c[i]

Python 3中，388个 398 373 371字节

假设有256个存储单元。只是简单易行的实施方式，容易打败，也许可以打更多的高尔夫。在repl.it上尝试。

感谢@EasterlyIrk让我意识到Python 3比Python 2短得多。

编辑：意识到我只在打印时考虑了上溢/下溢，而不是实际值。

感谢@ KevinLau-notKenney使用列表乘法和反转运算符技巧来节省25（！）字节

编辑：-3字节，将256放入变量，-4与运算符弄乱，+ 8确保其为小写

 b=256
 l,m=[w[-1]for w in s.lower().split()],[0]*b
