[Question]
  [
[Hodor](http://gameofthrones.wikia.com/wiki/Hodor) is a slow-minded but endearing character on the show [Game of Thrones](http://en.wikipedia.org/wiki/Game_of_Thrones) ([he's](http://awoiaf.westeros.org/index.php/Hodor) in [the books](http://en.wikipedia.org/wiki/A_Song_of_Ice_and_Fire) as well of course). The only word he ever says is ['hodor'](https://twitter.com/grrm/status/456824016641486848).
Surprisingly, despite not having much of a vocabulary, Hodor always speaks in complete sentences with correct capitalization and punctuation, and does in fact convey meaning.
Hodor is capable of expressing all 128 [ASCII](http://www.asciitable.com/) characters, though it takes him an entire sentence to say each one. Each character has a single, exact representation as a sentence. An ASCII string is *Hodorized* by translating all the characters in the string to their Hodor sentence equivalents, then joining all the sentences. Since all characters map to exact sentences, all ASCII strings have a single, unique Hodorized representation.
### Hodorizing Characters
Hodor divides his 128 expressible characters into 4 sets of 32 by using 4 different types of punctuation for the sentences that represent characters.
The sentence ends with...
* `.` if the ASCII character code [mod](http://en.wikipedia.org/wiki/Modulo_operation) 4 is 0.
* `.[newline][newline]` (for a new paragraph) if the code mod 4 is 1.
* `?` if the code mod 4 is 2.
* `!` if the code mod 4 is 3.
For example, the ASCII character code for `b` is 98, and 98 mod 4 is 2, so Hodor's sentence for `b` is sure to end in `?`.
The content of the sentence is one of 32 distinct strings only containing the word 'hodor'. Each of the 32 characters of a particular punctuation type map to a different sentence content string. So with 32 sentence content strings and 4 punctuation types, all 128 ASCII character can be represented as distinct Hodor sentences.
To determine the sentence content for a character with ASCII code C, compute `(floor(C / 4) + 16) mod 32`; everything after the colon on that line in this list is the sentence content:
```
0:Hodor
1:HODOR
2:Hodor hodor
3:Hodor, hodor
4:Hodor hodor hodor
5:Hodor, hodor hodor
6:Hodor hodor hodor hodor
7:Hodor hodor, hodor hodor
8:Hodor hodor hodor hodor hodor
9:Hodor hodor, hodor hodor hodor
10:Hodor hodor hodor hodor hodor hodor
11:Hodor hodor hodor, hodor hodor hodor
12:Hodor hodor hodor hodor hodor hodor hodor
13:Hodor hodor hodor, hodor hodor hodor hodor
14:Hodor hodor hodor hodor hodor hodor hodor hodor

17:Hodor hodor hodor hodor, hodor hodor hodor hodor hodor
18:Hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor
19:Hodor hodor hodor hodor hodor, hodor hodor hodor hodor hodor
20:Hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor
21:Hodor hodor hodor hodor hodor, hodor hodor hodor hodor hodor hodor
22:Hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor
23:Hodor hodor hodor hodor hodor hodor, hodor hodor hodor hodor hodor hodor
24:Hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor
25:Hodor hodor hodor hodor hodor hodor, hodor hodor hodor hodor hodor hodor hodor
26:Hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor
27:Hodor hodor hodor hodor hodor hodor hodor, hodor hodor hodor hodor hodor hodor hodor
28:Hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor
29:Hodor hodor hodor hodor hodor hodor hodor, hodor hodor hodor hodor hodor hodor hodor hodor
30:Hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor
31:Hodor hodor hodor hodor hodor hodor hodor hodor, hodor hodor hodor hodor hodor hodor hodor hodor
```
It can be seen that, apart from the `HODOR` special case, these strings are generated by joining more and more `hodor`'s, and every other string has a comma halfway between all the words (with the "larger half" right of the comma for an odd number of words).
Joining sentence content with punctuation, we can form the Hodor sentences for all 128 characters (the number on the left is the character code):
```

### Hodorizing Strings
Hodorizing a string really just involves concatenating all the character sentences of the string's characters together. There are only a couple caveats:
* A space is inserted after every sentence except for the `.[newline][newline]` punctuated ones and the very last sentence.
* If the last sentence is punctuated with `.[newline][newline]`, the punctuation becomes `...` so there is no trailing whitespace.
### Examples
The string `F0` is Hodorized as
```
HODOR? Hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor.
```
* `F` has ASCII code 70. 70 mod 4 is 2, so the first sentence ends in `?`. `(floor(70 / 4) + 16) mod 32` is 1 so the content is `HODOR`.
* `0` has ASCII code 48. 48 mod 4 is 0, so the second sentence ends in `.`. `(floor(48 / 4) + 16) mod 32` is 28 so the content is 15 `hodor`'s strung together with no comma.
* Notice that there is no trailing space.
The string `CEE` is Hodorized as
```
Hodor! HODOR.
HODOR...
```
* Notice that there is no space before the last sentence.
* Notice that the the last sentence punctuation was changed to `...`.
The string
```
Hodor's real name is Walder.
Did you know?
```
is Hodorized as
```

    HODOR:: r.Hodor Hodor!? Hodor? hodor hodor? (0,-1)
}
```
Yep, there is a language called [Hodor](http://www.hodor-lang.org/). (And it's rather new.) It's essentially just a string substitution for JavaScript. The corresponding JS looks like this:
```
function f(s){
  r='';
  l=s.length;
  for(i=0;i<l;++i){
    c=s.charCodeAt(i);
    n=(0|c/4+16)%32;
    r+='H';
    a=new Array(0|n/2+2);
    if(n%2)a[0|(n+1)/4]=',';
    r+=n==1?'ODOR':a.join(' hodor').slice(2);
    r+=['. ',i==l-1?'....':'.\n\n','? ','! '][c%4]
  }
  return r.slice(0,-1)
}
```
Hence, my submission is a function taking a string and returning the Hodorised equivalent.
Unfortunately, there doesn't seem to be any information about how Hodor actually works (apart from the source code of the interpreter), but it comes with a JS2HD translation script.
Note that Hodor's substitutions are also applied within string literals. So while you may just call the above function as
```
HODOR! ("CEE")
```
You can also use the following:
```
HODOR! ("Hodor... HooodorrHodor HooodorrHodor ")
```
where `Hodor... HooodorrHodor HooodorrHodor` will be substituted with `CEE`. Note that this means, that if your string itself contains certain forms of `Hodor` you'll *have* to encode it, or else it will be substituted. E.g. `"Hodor. "` is actually `"m"` in JavaScript. The catch is that the letters `[dhor]` (case insensitively) are not replaced at all, so you can't even encode this. One solution is to split up the literal, like `"Hod"+"or. "`, such that the substitution step doesn't find anything to decode.

# Python 2, ~~219~~ 198 bytes

Uses the same method as Martin's JavaScript, and it's several bytes shorter in Python. I make use of Python 2.7's handy integer division. Thanks to Sp3000 for some golfing.
```
def f(s,r='',i=2):
    for j in s:c=ord(j);n=(c/4+16)%32;a=['']*(n/2+2);a[-~n/4]=','[:n%2];r+='H'+[' hodor'.join(a)[2:],'ODOR'][n==1]+['. ',['.\n\n',4*'.'][i>len(s)],'? ','! '][c%4];i+=1
    return r[:-1]
```
And for your own entertainment and my own enjoyment and curiosity... 
Here it is as a **lambda function**!!!
### Python 2, 349
[Try it here](http://repl.it/jGL/3), along with an older version of the program above.
```
f=lambda s:'H'.join(['']+[('ODOR'if(ord(s[i])/4+16)%32==1 else' hodor'.join((['']*(((ord(s[i])/4+16)%32)/2+2))[:((ord(s[i])/4+16)%32+1)/4]+([',']if ord(s[i])/4%2 else[''])+(['']*(((ord(s[i])/4+16)%32)/2+2))[((ord(s[i])/4+16)%32+1)/4+1*(ord(s[i])/4%2<1):])[2:])+['. ',4*'.'if i+2>len(s)else'.\n\n','? ','! '][ord(s[i])%4]for i in range(len(s))])[:-1]
```
Creating this involved deeper and deeper substitutions as well as some extra creativity.
* Every `j` is replaced with `s[i]`.
* Every `c` is replaced with `ord(s[i])`.
* Every `n` is replaced with `(ord(s[i])/4+16)%32`.
	+ *Except* where I only need `n%2`, so I use `(ord(s[i])/4%2` instead.
* Finally, `a` is replaced with `(['']*(((ord(s[i])/4+16)%32)/2+2))[:((ord(s[i])/4+16)%32+1)/4]+([',']if ord(s[i])/4%2 else[''])+(['']*(((ord(s[i])/4+16)%32)/2+2))[((ord(s[i])/4+16)%32+1)/4+1*(ord(s[i])/4%2<1):]`.
	+ This is because we cannot assign a value, so we must split the list in half, conditionally append the comma, then append the last half again.

## [MUMPS](http://en.wikipedia.org/wiki/MUMPS), 284 236 bytes
New version: After looking at it for a while I came up with a shorter version (236 bytes):
```

 .S D=$A($E(H,O)),R=D#4,P=$S('R:".",R=2:"?",R=3:"!",O=L:"...",1:"."_$C(10,10)),E=D\4+16#32,(S,Q)="hodor" F F=1:1:E\2 S Q=S_$S(E#2&(F=(E\4+1)):", ",1:" ")_Q,$E(Q)="H" S:E=1 Q="HODOR"
 .W Q_P_$S(L=O:"",1:" ")
 Q
```
First version:
```
H(H) S L=$L(H) F O=1:1:L D
 .S S=$C(10),D=$A($E(H,O)),R=D#4,P=$S('R:".",R=2:"?",R=3:"!",O=L:"...",1:"."_S_S),E=D\4+16#32,(S,Q)="hodor ",G=6*(E+1\4) F F=1:1:E\2 S Q=S_Q
