Fairly obviously, you have to print the Greek alphabet. But I thought I'd make it slightly more interesting, so there's a twist: when your program is ran with an argument (anything), it should output the Greek alphabet in lowercase.

Information

  1. Greek alphabet (Capitals): ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ
  2. Greek alphabet (Lowercase): αβγδεζηθικλμνξοπρστυφχψω

Rules/Requirements

  • Each submission must be a full program.
  • Builtins to print the Greek alphabet are not permitted
  • Standard loopholes apply
  • You must print exactly what is shown.

Scoring

Programs are scored according to bytes. If you are using a character set different to UTF-8 please specify. Try to get the least bytes out of everyone, this is !

Test cases

./program
==> ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ

./program 1
==> αβγδεζηθικλμνξοπρστυφχψω

./program 'lower'
==> αβγδεζηθικλμνξοπρστυφχψω

./program 123897883421
==> αβγδεζηθικλμνξοπρστυφχψω

./program ""
==> αβγδεζηθικλμνξοπρστυφχψω

greek();
==> ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ

greek("blah");
==> αβγδεζηθικλμνξοπρστυφχψω

greek(123);
==> αβγδεζηθικλμνξοπρστυφχψω

Submissions

To make sure that your answer shows up, please start your answer with a headline, using the following Markdown template:

# Language Name, N bytes

where N is the size of your submission. If you improve your score, you can keep old scores in the headline, by striking them through. For instance:

# Ruby, <s>104</s> <s>101</s> 96 bytes

If there you want to include multiple numbers in your header (e.g. because your score is the sum of two files or you want to list interpreter flag penalties separately), make sure that the actual score is the last number in the header:

# Perl, 43 + 2 (-p flag) = 45 bytes

You can also make the language name a link which will then show up in the leaderboard snippet:

# [><>](http://esolangs.org/wiki/Fish), 121 bytes

Full program. I don't think a function/lambda answer will be shorter than this for this language.

Dangit, sigma ς. This is why we can't have nice things. And you too, (unrenderable character that serves as a placeholder for "uppercase" ς)

Because some of the uppercase Greek alphabet is not present in CP437, this solution is encoded in UTF-8 and scored accordingly. Here is a hexdump (reversible with xxd -r):

g=function(x)for(i in sprintf("'\\u%04X'",913:937+32*!missing(x))[-18])cat(eval(parse(t=i)))

Golfing down on the second version I had previously. Work the same way as previous version.

Thanks to @JDL for shaving off 7 bytes!

Old versions at 104 bytes:

I have two different solutions with the same byte count:

f=function(x){a="ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ";cat(if(missing(x))a else tolower(a))}

Or:

g=function(x)for(i in sprintf("'\\u%04X'",if(missing(x))913:937 else 945:969)[-18])cat(eval(parse(t=i)))

Explanations:

#First one is trivial
f=function(x){
     a="ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ" #String to print
     #If argument missing, print uppercase else lowercase 
     cat(if(missing(x))a else tolower(a)) 
     }
#Second one more interesting:
g=function(x)
     #Create escaped unicode strings (i. e. "'\\u03B1'" etc.), loop over them...
     for(i in sprintf("'\\u%04X'",if(missing(x))913:937 else 945:969)[-18])
          #...eval the strings
          cat(eval(parse(t=i))) 

Usage:

> f()
ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ
> g()
ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ
> f(1)
αβγδεζηθικλμνξοπρστυφχψω
> g(1)
αβγδεζηθικλμνξοπρστυφχψω
> f("a")
αβγδεζηθικλμνξοπρστυφχψω
> g("a")
αβγδεζηθικλμνξοπρστυφχψω

For some reasons, it doesn't work on R-Fiddle (it changes " to ' by default which makes the code throw an error) but you can try it out on Ideone.

print((('Α'to'Ρ')++('Σ'to'Ω')).mkString.map(& =>if(args.size<1)&else&toLower))

Ungolfed:

print((('Α'to'Ρ')++('Σ'to'Ω')).mkString.map(s=>if(args.size==0)s else s.toLower))

Sadly, (('Α'to'Ρ')++('Σ'to'Ω')) is a Vector[Char], which would be printed as Vector('Α', 'Β', ..., so it has to be converted to a string with mkString.The argument to map is called & to save spaces between &else, else& and & toLower.

PowerShell v2+, 68 bytes

(($a=-join([char[]](913..929+931..937))).toLower(),$a)[!$args.count]

ASCII-only, but outputs in UTF-16. Constructs a char-array of the appropriate characters, -joins it together into a string, stores it into $a. Then, uses !$args.count as an index into the tuple, to output either $a if no arguments are present, or $a.ToLower() if there is at least one argument.

  • \$\begingroup\$ gotcha. You seem somehow absent. $argc>1 is 8 bytes shorter than isset($argv[1]) and doesn´t need a blank. \$\endgroup\$ – Titus Jan 26 '17 at 1:00

Terribly golfed, maybe :(

And no, I can't use A.lower().

  • \$\begingroup\$ You can save 8 bytes by skipping the assignment to A,a, and just using those strings directly in the print. \$\endgroup\$ – alexwlchan Oct 22 '16 at 10:53

Script. Just takes the character range from Α to Ω, removes U+03A2/ς, either converts to lowercase or doesn't, and prints.

Perl under Windows -- console has no Unicode support -- (42 bytes, including spaces)

This is not my solution, I am just merely adapting the Perl solution of Denis Ibaev above, to Windows console Perl.

perl -E"say map{chr$_+151-!@ARGV*24}1..24"
ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ
$ perl -E"say map{chr$_+151-!@ARGV*24}1..24" with one or many arguments
αβγδεζηθικλμνξοπρσςτυφχψ

The console page code must be Greek of course:

chcp 737

NOTE: Just a small idea. On this page I can see that some of the answers use CHARACTERS that seem to been Unicode above 255. Therefore those characters take at least 2 bytes to code (perhaps 4 if one is using a console using 32bits Unicode chars?). Would not it be better if the contest measure was the CHARACTER unit (being Unicode or ASCII or EBCDIC ou whatever) rather than just BYTES? Would not it be simpler and more unifying (wonder if this adjectif exists in English, "unificateur" in French)?


Previous code in error: Does not print lowercase omega.

Corrected code (70 chars) :

perl -E"$i=!@ARGV+0;@a=73;pop@a if$i;say map{chr$_+151-$i*24}1..24,@a"
ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ
perl -E"$i=!@ARGV+0;@a=73;pop@a if$i;say map{chr$_+151-$i*24}1..24,@a" foo
αβγδεζηθικλμνξοπρσςτυφχψω

I know we are not supposed to print the 'end-of-word' sigma form ('ς') but as it is a mispelling error in ancient Greek to use regular sigma ('σ') at the end of a lowercase word, I choose to print it, as the tittle of this puzzle is "Print the Greek alphabet" and that this character is part of it...

       |                endif
        #<space>        Push 32 (ordinal of a space)
          9-            Subtract 9 (23)
            >           Move last item to start of stack
             [......]   Do-While loop, will run 24 times
              .         Duplicate last item
               !@       Print without popping
                  1     Push 1
                   +    Pop last 2 items (1 and duplicate) and push sum
