Another release of Rakudo Star. Let's see how can we get start using it on Mac OSX.

Note! This site is about Perl 6.
If you are looking for a solution for the current production version of Perl 5, please check out the Perl 5 tutorial.
=title Getting started with Rakudo * (2013.11) on Mac OSX

Before we get started

I use Homebrew for installing various open source libraries and technologies. As Rakudo relies on the ICU project for some of the Unicode features I installed it using

$ brew install icu4c

though I think in the end the Rakudo build process did not find it. I'll have to further research this.

Downloading Rakudo Perl 6

I read the most recent announcement and downloaded the latest release in source code version:

$ wget
$ tar xzf rakudo-star-2013.11.tar.gz
$ cd rakudo-star-2013.11

then I followed the instructions in the README file of the distribution. In a nutshell:

$ perl --gen-parrot

(I am sorry, I don't remember how I installed the original Perl 5 on this system. I think it came with XCode or was that Homebrew?. In any case, once I had that perl 5 installed I built my own version using Perlbrew. You can probably use any version of perl 5.)

$ make

Optionally also run the tests:

$ make rakudo-test
$ make rakudo-spectest

The first is fast, and only provides a minimal coverage. The second test-suite is big, and took a very long time to run.

$ make install

This will install the perl6 executable in the install/bin/ subdirectory of the rakudo-start-2013.11 directory where we built the whole thing.

Running Rakudo

At this point we can check if the installed version of Perl 6 runs:

$ ./install/bin/perl6 -v

This is perl6 version 2013.11 built on parrot 5.9.0 revision 0

Let's make it a bit more convenient:

The following commad

$ echo $(pwd)/install/bin

will print the full path to the bin directory (in my case it was /Users/gabor/work/rakudo-star-2013.11/install/bin )

then I edited ~/.bash_profile, and added:

# Rakudo
export PATH=/Users/gabor/work/rakudo-star-2013.11/install/bin:$PATH

and reloaded the file using:

source ~/.bash_profile

This let me run

$ perl6 -v

anywhere in the file system.

It will print the version number as above.

Simple command line Perl 6

Then try the following:

$ perl6 -e " 'Hello world'.say "

It should print the "standard" Hello world.


Because the p6doc command comes with Rakudo *, I can now type the following commands:

$ p6doc 

What documentation do you want to read?
Examples: /Users/gabor/work/rakudo-star-2013.11/install/bin/p6doc Str
          /Users/gabor/work/rakudo-star-2013.11/install/bin/p6doc Str.split

Then I can follow the instruction and type p6doc Str to get the documentation of the Str class.

The modules that come with this release of Rakudo * are listed in the modules/MODULES.txt in the unzipped directory.

When tyring the previous release of Rakudo (2013.10) some directories were missing from the distribution, and when I tried to install Panda mannually that failed too.

In this release, when I tried to run panda it got stuck. Apparently a problem on the server.

Nevertheless Rakudo can already be used for some tasks.

For examples this pages is generated by a set of Perl 6 scripts using the Rakudo * 2013.11.
