Print the Greek alphabet!

11

2

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

Does an empty string count as having an argument or having no argument? Please use the Sandbox to get feedback before posting a challenge on the main site.

– Mego – 2016-10-22T06:37:32.380

@Mego That counts as an argument. – George Gibson – 2016-10-22T06:38:23.890

2Related. – Erik the Outgolfer – 2016-10-22T08:36:31.657

2Will the argument be always one argument, or can there be two or more arguments? – Erik the Outgolfer – 2016-10-22T08:40:35.570

@EriktheGolfer In the test cases it's just one, so I guess there will only ever be one. – George Gibson – 2016-10-22T13:31:01.970

@GeorgeGibson Well, that would be convenient for my Python submission. – Erik the Outgolfer – 2016-10-22T13:37:22.013

Can nil, null, undefined, etc. be passed as an argument? – ETHproductions – 2016-10-22T15:35:31.403

Hebrew alphabet, Greek alphabet. Next stop: Chinese alphabet? – Glorfindel – 2016-10-22T16:49:44.207

@Glorfindel It's not an alphabet. Though technically, Hebrew isn't either. ;)

– DLosc – 2016-10-23T05:24:49.040

If there is no argument passed at all, do I output the uppercase alphabet? – Buffer Over Read – 2016-10-24T15:03:11.943

@TheBitByte Yes – George Gibson – 2016-10-25T17:05:57.280

Edit this into your question, and let everybody who's already answered know this – Buffer Over Read – 2016-10-26T03:54:27.017

Ruby, 56 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)

If a character array is acceptable, then for 82 80 78 bytes:

Using String.fromCharCode(...array) is again shorter: (...a)=>String.fromCharCode(...[...Array(24)].map((_,i)=>i+(i>16)+913+32*!!a.length)) – ETHproductions – 2016-10-22T15:27:10.863

1And since String.fromCharCode floors, you can save another two bytes like so: (...a)=>String.fromCharCode(...[...Array(24)].map((_,i)=>i*1.06+913+32*!!a.length)) – ETHproductions – 2016-10-22T15:29:30.790

@ETHproductions I can't believe I forgot to use String.fromCharCode(...) but I like that i*1.06 trick! Sadly comprehensions are a byte longer this time as far as I can tell. – Neil – 2016-10-22T16:48:47.430

I managed to get it down to (...a)=>String.fromCharCode(...[for(_ of Array(i=24))i++*42/41+889+32*!!a.length]) (82). – ETHproductions – 2016-10-22T17:16:04.337

You can remove the !!, as there will only be zero or one args. – ETHproductions – 2016-10-22T19:43:49.297

Using a single argument a, the expression 1/a+a should give truthy for every value of a except undefined. So a=>String.fromCharCode(...[...Array(24)].map((_,i)=>i*1.06+(1/a+a?945:913))) – edc65 – 2016-10-26T10:55:09.977

R, 104 99 92 bytes

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.

gotcha. You seem somehow absent. $argc>1 is 8 bytes shorter than isset($argv[1]) and doesn´t need a blank. – Titus – 2017-01-26T01:00:04.803

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.

This is the most golfed version I can do. – Erik the Outgolfer – 2016-10-22T10:34:53.520

You can save 8 bytes by skipping the assignment to A,a, and just using those strings directly in the print. – alexwlchan – 2016-10-22T10:53:16.740

@alexwlchan Right, I just didn't think of it... still terribly golfed, though. – Erik the Outgolfer – 2016-10-22T10:57:39.210

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...
