I'm kind of kidding, but Ruby lets you do things more elegantly than you can in Perl, and with less verbosity (hence the Java comment). It's really a syntax issue that I'm talking about, but it matters a lot for readability and language usability.
Perl:
my $x = 'Apple Carrot Banana';
# sort them into an array
my @y = sort split(' ', $x);
# do we have more than 2 elements? (just a random test)
if (scalar(@y) > 2) {
print "we've got ", scalar(@y), " elements!\n";
} else {
print "insufficient elements. fail.\n";
}
Ruby:
x = 'Apple Carrot Banana'
y = x.split(' ').sort
if (y.size > 2)
puts "we've got #{y.size} elements!"
else
puts 'insufficient elements. fail.'
end
Ruby just seems more elegant to me, more programmer-friendly. YMMV.
- chromatic 16y agoA modern Perl programmer might write something much more elegant: my $x = 'Apple Carrot Banana'; my @y = $x->split(' ')->sort; if (@y > 2) { say "we've got ${\@y->size} elements!"; } else { say "insufficient elements. fail."; }
- perigrin 16y agoAnd one that doesn't like autobox would say: use 5.12.2; # enables modern features my $x = 'Apple Carrot Banana'; my @y = sort split ' ', $x; say @y > 2 ? "we've got ${\scalar @y} elements!" : 'insufficient elements. fail.'; Not everything needs to be an Object. Not every call needs to be a method call. Some people think better with procedures, some people think better with objects. One of the reasons I personally like Perl is I can use which ever one is appropriate to the problem domain. Edit: forgot the `sort` call.
- colomon 16y agoOr ever-so-slightly lighter Perl 6 version: my $x = 'Apple Carrot Banana'; my @y = $x.words.sort; if @y > 2 { say "we've got {@y.elems} elements!"; } else { say "insufficient elements. fail."; }

- hyperbovine 16y agoIronic that the final rebuttal to "Perl looks like Java" is method chaining using periods :-) But hey, that looks very nice--glad to see Perl finally "got the dots." It's been years since I used Perl, mainly because I was squarely in the mindset of the OP. I'll have to give 6 a look.
