挑战

好吧，我认为这很清楚，不是吗？您必须创建一个函数或程序，该函数或程序将字符串作为参数并输出对应的Yoda语言。

这是code-golf，因此最少的字节数获胜。

输入

输入可以是没有换行符的任何字符串。如果字符串是这样组成的，则可以翻译它：

主语 +动词+其他。

其中Subject是人称代词（我，您，他，她，它，我们，他们）。您不必认识到第二个单词是动词。

如果第一个单词不是代词，则输入有效，但输出为 Too difficult, this sentence is.

You have to win this code challenge -> Translatable
Luke has to win this code challenge -> Untranslatable

输入可以以字母a结束。或！，而不是？。

此外，字符串可以包含Non-Ascii，括号，逗号，冒号...

输出

对于可翻译的句子，输出是相同的句子，主语和动词位于句子的末尾。

You have to win this code challenge -> To win this code challenge, you have.

代词中的逗号，句号和小写字母是必填项。（当然，如果代词是I）。

如前所述，如果不可翻译，则必须输出字符串 Too difficult, this sentence is.

例子

You have to win this code challenge -> To win this code challenge, you have.
He won this code challenge -> This code challenge, he won.  (I know this is not yoda-speaking, but I don’t want to overcomplicate this challenge)
I ate an ice cream earlier! -> An ice cream earlier, I ate.
I liked the Star Wars original trilogy more than the prequel’s one. -> The Star Wars original trilogy more than the prequel’s one, I liked.
I find your lack of faith disturbing -> Your lack of faith disturbing, I find.
I think we are done with the examples -> We are done with examples, I think.
He is your son, Vader -> Your son, Vader, he is.
I think they’ll add new features -> They’ll add new features, I think.
I made a fantastic code challenge (I hope) -> A fantastic code challenge (I hope), I made.
I love constants like π -> Constants like π, I love.

I’ll be the next President, I swear! -> Too difficult, this sentence is.
This challenge is great! -> Too difficult, this sentence is.
Is this challenge great? -> Too difficult, this sentence is.
Luke is not ready for this task -> Too difficult, this sentence is.
Somebody loves constants like π -> Too difficult, this sentence is.
[Empty string] -> Too difficult, this sentence is.

现在可以正确处理多个标点符号。测试用例：You will not win this challenge...! -> Not win this challenge..., you will.

在线尝试！

[.!]$

T`A-Z`a-z`^\w\w
G`^(I|we|you|s?he|it|they) \S+ \S
(\S+ \S+) (.*)
$2, $1.
T`a-z`A-Z`^.
^$
Too difficult, this sentence is.

描述：

如果最后有标点符号，请将其删除。

[.!]$

^empty line

将代词转换为小写，除了它是I。

T`A-Z`a-z`^\w\w

过滤掉任何不匹配的行 <Pronoun><space><word><space><word>...

G`^(I|we|you|s?he|it|they) \S+ \S

拆分为pronoun + verb，remainder。然后重新排列。

(\S+ \S+) (.*)
$2, $1.

将第一个字符转换为大写。

T`a-z`A-Z`^.

如果结果为空，则未通过上面的过滤器。打印错误信息。

^$
Too difficult, this sentence is.

ES6，212

这可能会进一步降低：

i=>(r=/(you|s?he|it?|we|they)( \S+) ([^\.!?]+)/i.exec(i))?(c=(a,b)=>a[`to${['Low','Upp'][b]}erCase`]())(r[3].slice(0,1),1)+r[3].slice(1)+", "+c(r[1],+(/i/i.test(r[1])))+r[2]+".":"Too difficult, this sentence is."

JSFiddle（需要使用最新的浏览器，例如Chrome）或通过node.js运行它

取消高尔夫：

i=>{
    r=/(you|s?he|it?|we|they)( \S+) ([^\.!?]+)/i.exec(i); //Main RegExp
    c=(a,b)=>a[`to${['Low','Upp'][b]}erCase`](); //shortcut for toUpperCase/toLowerCase
    if (r)
        return c(r[3].slice(0,1),1)+r[3].slice(1) + ", " //the "something else", properly formated
             + c(r[1], +(/i/i.test(r[1]))) //The subject lowercased except for "i" or "I"
             + r[2] + "."; //The End
    else //no match, no sentence to translate
        return "Too difficult, this sentence is.";
}

JavaScript（ES6），164个字节

s=>([,p,,i,r]=s.match`^(((I)|You|He|She|It|We|They) \\S+) (.*?)[.!]?$`)?r[0].toUpperCase()+r.slice(1)+`, ${i?p:p.toLowerCase()}.`:"Too difficult, this sentence is."

说明

在JavaScript中将一个字符串的首字母大写需要多少个字节几乎是痛苦的...

s=>

  // Match and get specific parts of the input string
  ([,p,,i,r]=s.match`^(((I)|You|He|She|It|We|They) \\S+) (.*?)[.!]?$`)?

    r[0].toUpperCase()+r.slice(1)     // capitalise first letter
      +`, ${i?p:p.toLowerCase()}.`    // lower-case the pronoun (unless it is I)
  :"Too difficult, this sentence is."

测试

测试不使用结构化分配来使其与跨浏览器更兼容。

var solution = s=>(p=s.match`^(((I)|You|He|She|It|We|They) \\S+) (.*?)[.!]?$`)?p[4][0].toUpperCase()+p[4].slice(1)+`, ${p[3]?p[1]:p[1].toLowerCase()}.`:"Too difficult, this sentence is."

<input type="text" id="input" value="I love constants like π...!" />
<button onclick="result.textContent=solution(input.value)">Go</button>
<pre id="result"></pre>

Python，261个字节

import re
def a(b):
 if b[-1:]in".!":
  b=b[:-1]
 if re.match('(I|YOU|S?HE|IT|WE|THEY) \w+ \S+',b.upper()):
  b=(b+',').split()
  if b[0]!="I":
   b[0]=b[0].lower()
  b=" ".join(b[2:]+b[:2])
  return b[0].upper()+b[1:]
 return "Too difficult, this sentence is."

事实证明，Python不会介意像b[-1]in".!"Next这样的事情，如果没人能击败我，我会更多地使用match对象：)

Python，第218个 217 204字节

不确定是否可以进一步打下去。

def f(s):t=s.split();u=' '.join(t[2:]).rstrip('!.');return['Too difficult, this sentence is.','%s, %s %s.'%(u[0].upper()+u[1:],['I',t[0].lower()][t[0]!='I'],t[1])][t[0]in'I We You He She It They'.split()]

取消高尔夫：

def f(s):
    t = s.split()
    u = ' '.join(t[2:]).rstrip('!.')
    return [
        'Too difficult, this sentence is.',
        '%s, %s %s.' % (u[0].upper() + u[1:],
                        ['I', t[0].lower()][t[0] != 'I'],
                        t[1])
    ][t[0] in 'I We You He She It They'.split()]

GNU sed，129个字节

我要为该-r标志添加+1字节。

#!/bin/sed -rf

/^I /b
s/^(You|[HW]e|She|It|They) /\L&/
t
s/.*/Too difficult, this sentence is./p
d
:
s/[.!]$//
s/^([^ ]+ [^ ]+) (.*)/\u\2, \1./

说明

如果我们匹配领先者，I我们将跳转到标签：

/^I /b

如果我们匹配其他代词之一，则将其缩小写，然后跳转至标签：

s/^(You|[HW]e|She|It|They) /\L&/
t

否则，我们将打印失败消息并移至下一个输入行：

s/.*/Too difficult, this sentence is./p
d

如果跳到标签，我们将删除所有最后的标点符号：

:
s/[.!]$//

然后将前两个词与句子的其余部分交换，将新的第一个词大写并添加所需的标点符号：

s/^([^ ]+ [^ ]+) (.*)/\u\2, \1./
