Using Symbols for Letters

Question

Input: A single word as a string (matches [a-zA-Z]+). If the input doesn't follow these guidelines, print "Error" (but no error should be thrown)

Output: The NATO pronunciation of the word. Print out a space separated list of the NATO word that matches each letter of the input word. Trailing white space is acceptable.

Restrictions:
Your source code must contain each ASCII character from 32 (space) to 126 (tilde) in that order, excluding numbers and letters. You may have anything you like mingled in between the required characters, but the required characters must be there and in order. (If ABC were the required characters, YA8iBC3 or C6ABn#C would be valid, but A7CRT or 8mdB9AC would not be).

Standard loopholes and built-ins for generating the NATO pronunciation are not allowed.

References:
The NATO pronunciation is as follows: Alpha Bravo Charlie Delta Echo Foxtrot Golf Hotel India Juliet Kilo Lima Mike November Oscar Papa Quebec Romeo Sierra Tango Uniform Victor Whiskey Xray Yankee Zulu.

The required symbols (in order) are as follows: !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~

Test cases: (The quotation marks won't be part of input, but are included to show whitespace)

"a"            => Alpha
"Z"            => Zulu
"twig"         => Tango Whiskey India Golf
"PPCG"         => Papa Papa Charlie Golf
"camelCase"    => Charlie Alpha Mike Echo Lima Charlie Alpha Sierra Echo
"Quebec"       => Quebec Uniform Echo Bravo Echo Charlie
""             => Error
" "            => Error
"()"           => Error
"twig "        => Error
" PPCG"        => Error
"one+two"      => Error
"Queen bee"    => Error

This is a code-golf, so the shortest code in your favorite language wins!

Answer 1

JavaScript (ES6), 268

An anonymous function

i=>[...i].every(c=>(c=parseInt(c,36))>9?o+="AlphaBravoCharlieDeltaEchoFoxtrotGolfHotelIndiaJulietKiloLimaMikeNovemberOscarPapaQuebecRomeoSierraTangoUniformVictorWhiskeyXrayYankeeZulu".match(/[A-Z][^A-Z]+/g)[c-10]+' ':0,o='',!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~")?o:'Error'

Answer 2

Ruby, 343 bytes

puts gets.chop.chars.map!{|c|"AlphaBravoCharlieDeltaEchoFoxtrotGolfHotelIndiaJulietKiloLimaMikeNovemberOscarPapaQuebecRomeoSierraTangoUniformVictorWhiskeyXrayYankeeZulu"[/#{c.upcase}[a-z]+/]||$$%0&0}*' 'rescue(puts"Error")#*+,-./:;<=>?@[\]^_`{|}~

Tried incorporating as many of the required characters as possible, but after a while it was shorter to just put them in a comment at the end. For readability, here's the non-comment part with the long string taken out:

puts gets.chop.chars.map!{|c|"AlphaBravo..."[/#{c.upcase}[a-z]+/]||$$%0&0}*' 'rescue(puts"Error")

That's a space and all the characters !"#$%&'() in the right order without comments

-8 bytes implicitly thanks to @ErikTheGolfer's comment here for a better compressed string (only difference is Alpha vs Alfa).

Try it online or verify all test cases.

Explanation:

!              # Take the factorial of the (implicit) input
               # (This will leave the input-string unchanged if it isn't an integer)
 áм            # Remove all letters
   g_i         # If the length of the remainder is 0:
      l        #  Make the (implicit) input lowercase
       A       #  Push the lowercase alphabet
       ”¤±Ð†vo¼¯¤œ®È¨›trotŠˆƒ‹Š™ÈŸt Kilo´àma—……ÍЗŽêpa¼°«Äoµ†Çâgo¸šÉµ Whiskey Xrayµ‹nkeeâ¸lu”
               #  Push string "Alpha Bravo Charlie ... Yankee Xray Zulu"
        #      #  Split the string by spaces:
               #   ["Alpha","Bravo","Charlie",...,"Yankee","Xray","Zulu"]
         ð«    #  Append each with a space:
               #   ["Alpha ","Bravo ","Charlie ",...,"Yankee ","Xray ","Zulu "]
       ‡       #  Transliterate; map all letters in the lowercase input with this
               #  list at the same indices (and output the result implicitly)
     ë         # Else:
      ”‰ë”     #  Push the dictionary word "Error"
          q    # Stop the program (and output the "Error" at the top of the stack implicitly)
           "#$%&'()*+,-./:;<=>?@[\]^_`{|}~
              "# Push the string "#$%&'()*+,-./:;<=>?@[\]^_`{|}~",
               # which is a no-op since the program has already stopped

See this 05AB1E tip of mine (section How to use the dictionary?) to understand why ”¤±Ð†vo¼¯¤œ®È¨›trotŠˆƒ‹Š™ÈŸt Kilo´àma—……ÍЗŽêpa¼°«Äoµ†Çâgo¸šÉµ Whiskey Xrayµ‹nkeeâ¸lu” is "Alpha Bravo Charlie Delta Echo Foxtrot Golf Hotel India Juliet Kilo Lima Mike November Oscar Papa Quebec Romeo Sierra Tango Uniform Victor Whiskey Xray Yankee Zulu" and ”‰ë” is "Error".

Answer 5

PHP, 268 bytes

Same byte count as the JavaScript answer. :) I couldn't find a byte-saving way around the "penalty" of adding the special char string as is:

for(;$c=ucfirst($argv[1][$i++]);"!\"#$%&'()*+,-./:;<=>?@[\]^_`{|}~")preg_match("/{$c}[a-z]+/",AlphaBravoCharlieDeltaEchoFoxtrotGolfHotelIndiaJulietKiloLimaMikeNovemberOscarPapaQuebecRomeoSierraTangoUniformVictorWhiskeyXrayYankeeZulu,$m)?$o.="$m[0] ":die(Error);echo$o;

Takes an input from command line, like:

$ php tango.php Word

Reads input from command line, displays output to console.

Implementation notes: In order to prevent any otherwise valid words from being displayed before the Error string, the searching and screen output are separate. The input string is searched end to beginning since the stack (LIFO) is used to hold the output words (otherwise they'd be displayed in reverse).

Output:

Japt, 188 bytes

The compressed string is littered with unprintables, so I've replaced each with a ¿. Try it online!

V=Um@`Alp¿B¿voC¿r¦eDeltaE®oFoxÉ¿GolfHÇUI¿iaJªietKiloL¿aMikeNovem¼rOs¯rPapaQue¼cRo´oSi¿¿TangoUnif¿mVÅ¡rW¿skeyX¿yY¿keeZªu`fXu +"[a-z]+" +S};!Uf"[ !#$%&'()*+,-./:;<=>?@[\\]^_`\{|}~]" ?V:`Er¿r
                                                                                                                                     ^    ^  ^   ^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^

The top line is the actual code; the bottom line points out each of the required characters. I was lucky to find a way to put every one of them to good use, especially the backslash, which would have been needed there even if it was not required.

I could save four bytes by using JS's atob to compress the string, instead of Japt's built-in Oc, but the transpiler inserts an extra parenthesis due to this bug.

V=Um@     }; // Set variable V to: map each character X in U to:
`...`f       //  Take the long string, decompress it, and match:
Xu +"[a-z]+" //   the uppercase version of X, followed by multiple lowercase letters.
+S           //  Take the resulting match and add a space.
             // All this results with "Alpha Bravo Charlie" for an input of "Abc", or
             // "Alpha Bravo null" for something like "Ab!".
 Uf"..."     // Match any of the characters in this string in the input.
!        ?   // If the result is null (none were matched):
V            //  output V.
:"Error      // Otherwise, output "Error".

Python 279 276 bytes

It would have been much shorter than the odd requirement.

EDIT: I just learned that s.split(' ')==s.split()

#!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
x=raw_input().lower();a=''
l="Alpha Bravo Charlie Delta Echo Foxtrot Golf Hotel India Juliet Kilo Lima Mike November Oscar Papa Quebec Romeo Sierra Tango Uniform Victor Whiskey Xray Yankee Zulu".split()
for i in x: a+=l[ord(i)-97]+' '
print a

I commented out the requirement. I used ord() to find the index position of the letter in l.
