# Code golf for my real friends

...and real golf for my code friends.

This is a challenge based on a one year old XKCD comic which consists mostly of toasts (parodies of the first in the comic) following a distinct pattern, but with some slight variation.

Your task is to write a program (or function) that takes the first half of any toast from the comic (everything up to and including the friends) as input (via stdin or a function argument) and outputs (or returns) the precise text of the second half. You do not have to handle invalid input, standard loopholes apply, shortest code in bytes wins.

### Examples

To help those who don't want to copy the toasts from anywhere else, here are all of them, separated into input and output.

Input: Champagne for my real friends
Output: and real pain for my sham friends!

Input: Pseudopods for my real friends
Output: and real pods for my pseudo-friends!

Input: Petticoats for my real friends
Output: and real coats for my petty friends.

Input: Loosestrife for my real friends
Output: and real strife for my loose friends!

Input: Ladybugs for my real friends
Output: and real bugs for my lady friends!

Input: Single-payer for my real friends
Output: and RealPlayer for my single friends.

Input: Tumbleweeds for my real friends
Output: and real weed for my Tumblr friends!

Input: Fauxhawks for my real friends
Output: and real hawks for my faux friends!

Input: Platonic solids for my real friends
Output: and real solids for my platonic friends!

• I think you have a typo at Single-payer (instead of Single-player). Mar 13, 2017 at 11:08
• Kevin: No. It really is Single-payer. Mar 13, 2017 at 12:23
• @KevinCruijssen - It might be a typo, but if so it's Randall@XKCD's, not ivzem. There's a discussion of it on Explain xkcd. Also, ivzem - as soon as I saw the title in the HNQ list, I was sure you were referencing that comic. Well done! Mar 13, 2017 at 21:45

The previous version didn't manage correctly the space in "platonic solids", this one works and is shorter :)

ew
rw
eds
ed
(\w+) ?([^oatr ]\w{3}.+)real
and real $2$1
C
S
gne
in
o
o-
ti
ty
TTLTl
p\w+y.+
$&. s$
s!
real -p
RealPl


Try it online!

This transforms the input into the output through a series of substitutions.

The most interesting part is this substitution (kind of a regex golf):

(\w+) ?([^oatr ]\w{3}.+)real
and real $2$1


Which does almost all the job, by splitting the first word, placing its pieces in the right places, removing extra spaces, and building the structure of the output. To work correctly on the "Tumbleweeds" test case this depends on the previous substitution "eds"->"ed".

The rest is mostly composed by substitutions that deal with special cases. Other interesting parts are:

TTLTl


This turns everything except "T" (for Tumblr) to lowercase.

p\w+y.+
$&. s$
s!


This places a "." at the end of each sentence containing a word with a "y" some letters after a "p" ("petty" and "payer" in practice). Then places a "!" at the end of all sentences ending with an "s" (all the others).

• This prints an extra space after platonic. Suggested fix: TIO (+5 bytes) Mar 13, 2017 at 15:18
• @math_junkie Thank you, I've uploaded a new version which fixes the problem with spaces and is even shorter :)

Thanks to Erik the Outgolfer for saving 22 bytes!

+24 bytes to account for some outputs ending in . instead of !

Simple solution to start things off. Checks the eighth letter of the input, as suggested in the comments, and looks up the corresponding output in a dictionary an array.

This is now my fifth attempt. I've managed to half the size of my original program. It now includes the missing "-" and I believe is a complete solution. Still I suspect on the bulky side; but much closer to the goal. I've had a lot of help. Thanks for all the helpful guidance.

s=input()
x=0
a,b,c,d,e,f,g,h = " and real","for my","friends",".!","print(a,l[p+1],b,l[p+2]",",c+d[0])","+c+d[1])",",c+d[1])"
for p in range(0,27,3):
x+=1
if s[:2] == l[p]:
if x == 2: eval(e+g)
else: eval(e+f if x in(3,6) else e+h)

Original Posting

This is my first post on code golf so apologies in advance for my clumsy program. Can't see how a program could be made to convert "Champagne" to "pain", "sham" by parsing the words. However I would like to see someone else solve that. So, as my level of ability dictates that my program needs to know in advance that "Champagne" is "pain", "sham", there seemed little point in actually coding an input request. As a result I've left it out and been a bit literal with my print output. Hope that's ok : )

phraseList= [   ("Champagne","pain","Sham"),
("Psudeopods","pods","psuedo-"),
("Petticoats","coats","petty"),
("Loosestrife","strife","loose"),
("Single-payer","coats","petty"),
("Petticoats","RealPlayer","single"),
("Tumbleweeds","weed","Tumblr"),
("Fauxhawks","hawks","faux"),
("Platonic solids","real solids","platonic")
]

for phrase in phraseList:
print("Input: ",phrase[0], "for my real friends.")
if "-" in phrase[2]:
print("Output: and real", phrase[1], "for my", phrase[2]+ "friends!")
else:
print("Output: and real", phrase[1], "for my", phrase[2], "friends!")

• Hello and welcome to the site. This is a code-golf question which requires you to make an effort to minimize the length of your code. You should remove unnecessary whitespace and rename variables to be 1 character long. Mar 12, 2017 at 16:27
• You can put the whole phraseList in one line, reduce the indention to one space, put the prints together in one line with if and else, and the whitespace in the prints isn't necessary. Anyway, I do not know if you're allowed to just print all outputs ;) Mar 12, 2017 at 16:28
• Hello! It seems like this is your first code golf answer. Unfortunately, you seem to have misunderstood the question, especially the "Examples" table at the bottom, which just shows how each input should map to a respective output. Currently, your program just prints that table._Also, it is standar practice to place your code in a code block (select it and click the {}) for better readability and to mention your language of choice and byte count, as this site is more like a competition than a Q&A site._ Wheat Wizard already did that, so that's better Mar 12, 2017 at 16:30
• Hi and welcome to PPCG. You could lose a lot of bytes by removing spaces and using single letter variables. I remember when I first started here it took some time to get used to. I guess you are like me. You spend a lot of time writing readable code. As I said, welcome to PPCG and a new world ;) Mar 12, 2017 at 19:27

Bytes saved thanks to @fergusq showing me the way of indexOf

Try it online!

So close to Python... so close.... Your move, Python.

### Explanation

h a{
r=indexOf(a[7:8],"noarspekc")  /*Gets the index of the character in this string*/
/*Variable A contains all the unique words for each test case*/
A="pain>pods>coats>strife>Player>bugs>weed>hawks>solids>sham >pseudo->petty >loose >lady >single >Tumblr >faux >platonic >!>!>.>!>!>.>!>!>!"/">"
["and "]
["Real"]if[r=4]else["real "]   /*RealPlayer*/
[A[r]," for my ",A[r+9],"friends",A[r+18]]   /*Print everything using var A*/
}

• Can you save one byte by using string interpolation in the last statement? Edit: actually the shortest way is probably to push many strings to the stream instead of one, ie. replace .. with ,. Mar 12, 2017 at 20:08
• @fergusq Thanks for the tip! Mar 12, 2017 at 20:14
• Also you can just use r=indexOf(a[7:8],"noarspekc"). Mar 12, 2017 at 20:28
• @fergusq Ah, I didn't know such a builtin existed. Thanks! Mar 13, 2017 at 5:35

Can definitely be golfed by using something different than a Map..

Explanation:

//  Add mapping from first two characters with first word
put("Ch1","sham ");put("Ps1","pseudo-");put("Pe1","petty ");put("Lo1","loose ");put("La1","lady ");put("Si1","single ");put("Tu1","Tumblr ");put("Fa1","faux ");put("Pl1","platonic ");
//  Add mapping from first two characters + "1" with second word (+ space or '-' for edge-case pseudo-friends)
}};                          // End of Map initialization
String r=s.substring(0,2);   //  Get the first two characters of the input String
int c=r.charAt(1);           //  Get the second character
return "and "                //  return "and "
+ (c=='i'?"Real":"real ")  //   + "Real" or "real " for edge-case RealPlayers
+ m.get(r)                 //   + first word from Map
+ " for my "               //   + " for my "
+ m.get(r+1)               //   + second word from Map

+ (c=='i'|c=='e' ? '.'     //   + '.' for edge-cases 'Petticoats' and 'Single-player
: '!');                  //     or '!' for all other cases
}                              // End of method
