问题:

When thanking someone, you don't want to just send them an e-mail saying "Thanks!", you want to have something FLASHY:

Input: THANKS!!
Output:
TTT H H AAA N N K K SSS !!! !!! 
 T  H H A A NNN K K S   !!! !!! 
 T  HHH AAA NNN KK  SSS !!! !!! 
 T  H H A A N N K K   S            
 T  H H A A N N K K SSS !!! !!!

Write a program to generate a banner. You only have to generate upper-case A-Z along with spaces and exclamation points (what is a banner without an exclamation point?). All characters are made up of a 3x5 grid of the same character (so the S is a 3x5 grid made of S). All output should be on one row (so no newlines). Here are all the letters you need:

Input: ABCDEFGHIJKL
Output:

The winner is the shortest source code, as counted by the number of bytes it takes to store the file in utf-8 encoding. Source code should read input from stdin, output to stdout. You can assume input will only contain [A-Z! ]. If you insult the user on incorrect input, you get a 10 character discount =P.

I was going to require these exact 28 characters, but to make it more interesting, you can choose how you want them to look - whatever makes your code shorter! To prove that your letters do look like normal letters, show the output of the last three runs.

Shortest codes so far, in characters (utf8 encoding if non-ASCII present):

133 J

205 Python

209 Ruby

313 Haskell

345 C89

382 F#

For the curious, the large number is the hex version of encoding in the following code. The number is simply used as a bitmap. I've had no success with further shortening the code by encoding the number to other bases even with non-standard character representations.

formats :: [String] -- order: [ A-Z!] <- that's a space in front of A
formats = [

Python 2.6, 251 - 243 - 227 characters

I tried a slightly different approach (bitpacking the parts the letters are made of) ...

  • handles uppercase letters, spaces, exclamation mark.
  • 2 unnecessary linebreaks added here for readability (the for loop could be one line)
  • be sure to save this as UTF-8 with BOM!

As always, all comments and suggestions welcome! Contender for shortest Python solution (again a few characters behind at the moment)...

Ok, with all the begin/end statements Delphi probably will never be shorter than any other languages, but I do see a challenge in getting it as short as possible.

The characters in this 5x3 font take up 15 bits and are stored in word (UINT16) in this order:

Formatted code:

I'm a bit late but this just looked like fun. 

using C=System.Console;class P{static void Main(){var t=C.ReadLine();for(int
b=15,s;b>0;b-=3){foreach(var c in t)for(s=0;s++<4;)C.Write(s>3||c<33?' ':((
"翇篭篯礧歮禧禤祯寭璗牯宭䤧彭忭筯篤筿殭秏璒孯孪寿咕寏犧"[c<34?0:c-64])&1<<b-s)>0
?c:' ');C.WriteLine();}}}
