Perl 6 Now
by Scott Penrose
Why
Perl 6 is fun. It's here now. It's fully functional. It has a fantastic, open and fun community.
It's ready to use now.
Which version?
There are a number of complilers available, this talk
concentrates on Rakudo.
Why not...
The main reasons are: Performance (it is still slow but improving daily); Learning curve (don't start using Perl 6 for a project with a short deadline); It's changing.
When will it release or be ready?
My simple answer... When it is being used by developers.
Installation
Any Unix (including Mac) with git, subversion, gcc, make and ICU library.
git clone git://github.com/rakudo/rakudo.git
cd rakudo
perl Configure.pl --gen-parrot
make
sudo make install
Or you can find a precompiled Windows binary
Getting started
Start with "Hello OSDC 2009"
"Hello OSDC 2009".say;
Apply your Perl 5 knowledge
- Sygil changes (or rather doesn't)
- Try a scalar - my $year = 2009; say $year;
- Try an array - my @arr = 2005, 2006, 2007, 2008, 2009; say @arr[4];
- Try a hash - my %hash; %hash<Year> = 2009; say %hash<Year>
- Dealing with files?
- Open a file - my $input = open('input.txt', :r);
- Read the lines - say $input.get
- Write to a file - my $out = open('output.txt', :w); $out.print("Hello OSDC\n");
