Michaud <pmichaud(a)pobox.com> Date: Mon, Feb 1, 2010 at 14:09 Subject: Announce: Rakudo Perl 6 Development Release #25 ("Minneapolis") To: perl6-language(a)perl.org, perl6-users(a)perl.org, perl6-announce(a)perl.org, parrot-dev(a)lists.parrot.org [This notice is going out a bit late; the release was indeed produced on time, but I was delayed in sending out this notice. With apologies for the delay... --Pm] On behalf of the Rakudo development team, I'm pleased to announce the January 2010 development release of Rakudo Perl #25 "Minneapolis". Rakudo is an implementation of Perl 6 on the Parrot Virtual Machine (see http://www.parrot.org) The tarball for the January 2010 release is available from http://github.com/rakudo/rakudo/downloads . Rakudo Perl follows a monthly release cycle, with each release code named after a Perl Mongers group. The January 2010 release is code named "Minneapolis" for Minneapolis.pm, hosts of the annual Frozen Perl Workshop [1]. In 2009 the Frozen Perl Workshop featured a one-day hackathon for Perl 6 and Rakudo development, which ultimately informed the design and implementation of the current build system. (The 2010 Frozen Perl Workshop will be on February 6, 2010, for those interested in attending.) Shortly after the October 2009 (#22) release, the Rakudo team began a new branch of Rakudo development ("ng") that refactors the grammar to much more closely align with STD.pm as well as update some core features that have been difficult to achieve in the master branch [2, 3]. We had planned for this release to be created from the new branch, but holiday vacations and other factors conspired against us. This is absolutely the final release from the old development branch; we expect to make the new branch the official "master" branch shortly after this release. This release of Rakudo requires Parrot 2.0.0. One must still perform "make install" in the Rakudo directory before the "perl6" executable will run anywhere other than the Rakudo build directory. For the latest information on building and using Rakudo Perl, see the README file section titled "Building and invoking Rakudo". Some of the specific changes and improvements occuring with this release include: * Rakudo is now passing 31,957 spectests, or 85.7% of the available test suite. This is roughly the same level as the December 2009 release (because most effort has taken place in the "ng" branch as described above). * Rakudo's calling conventions have been updated to match changes in Parrot 2.0.0's calling and context structures. The Perl 6 language specification is still in flux. Please take note of the following changes, which might affect your existing programs. In the next release of Rakudo, the deprecated features will likely be gone. * The root of the object hierarchy has been changed from 'Object' to 'Mu'. The type 'Object' goes away. * The term 'undef' is gone. You can replace it with other constructs, depending on context: - 'Nil' is undefined in item context, and the empty list in list context - 'Mu' is the most general undefined value which does not flatten in list context - as a smart matching target, you can replace '$obj ~~ undef' by '$obj ~~ *.notdef' * Builtin classes will derive from 'Cool' (which itself derives from 'Any'). Most of the builtin methods on these classes will be defined in the 'Cool' class instead of 'Any'. See Synopsis 2 for more details. * Starting with the next release, we will likely switch to using "YYYY.MM" instead of "YYYY-MM" (dot instead of hyphen) as release identifiers. This is intended to simplify building and packaging for other distribution systems. The development team thanks all of our contributors and sponsors for making Rakudo Perl possible. If you would like to contribute, see http://rakudo.org/how-to-help , ask on the perl6-compiler(a)perl.org mailing list, or ask on IRC #perl6 on freenode. The next release of Rakudo (#26) is scheduled for February 18, 2010. A list of the other planned release dates and codenames for 2010 is available in the "docs/release_guide.pod" file. In general, Rakudo development releases are scheduled to occur two days after each Parrot monthly release. Parrot releases the third Tuesday of each month. Have fun!
