Sort by custom alphabet

Question

The challenge is to make a program that sorts a list of words, only that the words need to be in the order of a random given alphabet.

Your program will accept a string of comma-separated words and a new alphabet.
Your program will output every word in the same way in the new sorted order.

Example:

Input:

home,oval,cat,egg,network,green bcdfghijklmnpqrstvwxzaeiouy

Output:

cat,green,home,network,egg,oval

This is a code-golf, so the winner is the person with the shortest program.

This is my first challenge so any improvements to the question/challenge are appreciated.

Answer 1

CJam, 26 19 17 bytes

rr:A;',/{Af#}$',*

Try it online.

Test case

$ cjam sort.cjam <<< 'home,oval,cat,egg,network,green bcdfghjklmnpqrstvwxzaeiouy'
cat,green,home,network,egg,oval

How it works

rr                    " Read two whitespace-separated tokens from STDIN. ";
  :A;                 " Save the second token (the alphabet) in A.       ";
     ',/              " Split the remaining token at commas.             ";
        {Af#}$        " Sort by the chunks' characters' indexes in A.    ";
               ',*    " Join, separating by commas.                      ";

Answer 2

Bash+coreutils, 37 bytes

tr ,$2 \\na-z<<<$1|sort|tr \\na-z ,$2

Output:

$ ./alphasort.sh home,oval,cat,egg,network,green bcdfghijklmnpqrstvwxyzaeiouy
cat,green,home,network,egg,oval, $ 

Answer 3

Pyth, 19 characters

j\,o_mx_zdNchczd\,

Test:

$ pyth -c "j\,o_mx_zdNchczd\," <<< 'home,oval,cat,egg,network,green bcdfghjklmnpqrstvwxzaeiouy'
cat,green,home,network,egg,oval

Explanation:

                            Implicit: d=" "
                            Implicit: z=input()
j\,                         ",".join(
   o                                 order_by(lambda N:
    _                                                  rev(
     m                                                     map(lambda d:
      x_zd                                                              rev(z).index(d),
      N                                                                 N),
    chczd\,                                            z.split(" "[0].split(",")

Essentially, it sorts the chunks, with a key of the list of indexes of the characters in the string, then joins them on commas. The reversal businesses is shorter than spliting the string again.

Answer 4

Ruby, 53 50 bytes

a,b=$*
$><<a.split(?,).sort_by{|w|w.tr b,'a-z'}*?,

I'm using Ruby's tr to replace the custom alphabet with a-z before sorting. Input is via command-line argument.

Answer 5

Clojure, 115 bytes

#(apply str(butlast(interleave(sort-by(fn[w](apply str(map(zipmap(sort %2)%2)w)))(re-seq #"[a-z]+"%))(repeat \,))))

Wow, this started of well with (sort-by(fn[w](mapv(zipmap(sort %2)%2)w))) but then I realized vec don't get sorted the same way as strings, and interleaving those commas takes significant amount of code as well.

Answer 6

JavaScript (E6) 102 119

Sort with a mapping function 'M' based on the alphabet in variable 'a'
With IO using popup (prompt + alert)

x=prompt().split(/[ ,]/),
a=x.pop(),
M=w=>[10+a.search(c)for(c of w)]+'',
alert(x.sort((a,b)=>M(a)>M(b)))

As a (testable) function with 1 string parameter, returning a string array (92)

F=x=>(
  M=w=>[10+a.search(c)for(c of w)],
  x=x.split(/[ ,]/),
  a=x.pop(),
  x.sort((a,b)=>M(a)>M(b))
)

Test In FireFox/FireBug console

F('home,oval,cat,egg,network,green zyxwvtsrqpnmlkjhgfdcbaeiou')

Output

["network", "home", "green", "cat", "egg", "oval"]

Answer 7

Python, 131

w,a=input().split()
print(",".join(sorted(w.split(","),key=lambda s:"".join(["abcdefghijklmnopqrstuvwxyz"[a.find(c)]for c in s]))))

There should be plenty of room for improvement.
