definitely less keystrokes
for i in (1..10) puts i end

or even shorter
(1..10).each { |i| puts i }

what about...
puts (1..10).to_a * "\n"

Ok now I doubt you could make this any shorter
puts (1..10).to_a

This also works, though it isn't shorter. It looks nice, though.
1.upto(10) { |i| puts i }

You could save that line into a separate file as a library, and then actually call it really easily!
load "x"

I think we have a winner... the
puts *(1..10)
!
but actually
p *(1..10)
works too :)

AFAIK, you can lose () also ? Another 2 characters down...

Using range is really cool thing In ruby.
Also, .times is cool feature

Brian,
All ruby loops are cool and creative. Whether range or times or until. It is just great programming language.

Using range is cool. I would also suggest using times. Like
10.times do |x|
puts x
end
Thanks

@Sakari, I don't this is "stupid," if you're trying to learn Ruby (like me).
Anyway, I think that do end is the same as {}, so could be written (shorter)...
[I'm sure my code will be totally weird here]...
10.times do |x| puts x end
10.times { |x|
puts x
}

(1..10).each do |i| puts i end
(1..10).each { |i|
puts i
}

@Daniel Rosenstark yes do / end and {} are both closure literals when in the correct context. {} us typically used for one-liners where as do / end in multi-liners (not always the case though obviously) this is a pretty funny exercise, the range splat is cool though. I am not sure exactly of the C implementation but splat does call #to_ary so you can do things like this
class Foo
def to_ary
return 1,2,3,4,5
end
end
def bar *args
p args
end
bar *Foo.new # => [1, 2, 3, 4, 5]

I do enjoy the .times way best
# Print your name in reverse X times.
printf("Enter a numer: ");
my_num = gets.strip.to_i;
printf("What's your name: ");
name = gets.strip;
my_num.times {|i|
printf("%d.\t%s\n",i,name.reverse);
}

I'm learning Ruby/Haml and this is useful to learn.
I'm actually looking for a way to do the same thing taking the number from a symbol variable. Something like the code below, but any version doesn't work.
How could I better make it work?
:questionNum.times do |x| puts x end for i in (1..@questionNum) puts i end

One character less:
p *1..10
kinofrost
August 23, 2011, August 23, 2011 03:38, permalink
It should be noted that "puts" and "p" are not equivalent, so it should only refactor using "puts"; so this is the shortest:
puts *1..10
