Announce: Rakudo Perl 6 development release #19 ("Chicago")

(Note: This was meant for the front page, but that submission is still "pending", while newer ones were accepted. I guess that really means "rejected". Oh, well, now it goes here)

On behalf of the Rakudo development team, I'm pleased to announce the July 2009 development release of Rakudo Perl #19 "Chicago". Rakudo is an implementation of Perl 6 on the Parrot Virtual Machine [1]. The tarball for the July 2009 release is available from http://github.com/rakudo/rakudo/downloads .

Due to the continued rapid pace of Rakudo development and the frequent addition of new Perl 6 features and bugfixes, we continue to recommend that people wanting to use or work with Rakudo obtain the latest source directly from the main repository at github. More details are available at http://rakudo.org/how-to-get-rakudo .

Rakudo Perl follows a monthly release cycle, with each release code named after a Perl Mongers group. The July 2009 release is named "Chicago", as chosen by Perl 6 contributor Kyle Hasselbacher. Kyle has been doing a truly outstanding job of turning open tickets in the RT queues into tests for the spectest suite. Chicago.pm has been the host for the 2006 and 2008 YAPC::NA conferences and sponsored Perl 6 hackathons at each conference.

In this release of Rakudo Perl, we've focused our efforts on quality improvements and bootstrapping. We now have operators and additional builtin functions written in Perl 6.

Some of the specific major changes and improvements in this release include: * Rakudo is now passing 11,876 spectests, an increase of 340 passing tests since the June 2009 release. With this release Rakudo is now passing 68% of the available spectest suite. * Operators can now be written in Perl 6, and this has been done for the series operator '...', 'eqv' and the 'leg' operator.

* The multi dispatcher has been refactored extensively, and now handles many more edge cases correctly. * User defined traits now follow the specification much more closely; some built-in traits are written in Perl 6.

* Improved testing: Null PMC Access exceptions are never considered "successful" by the test suite, even if the test was expecting a (different) exception to be thrown.

* Improved introspection: you can now get a list of roles composed into a class, and a list of attributes.

Since the Perl 6 specification is still in flux, some deprecated features will be removed from Rakudo. Prominently among those are:

* '=$handle' is deprecated in favor of '$handle.get' (one line) and '$handle.lines' (all lines).

* 'int $obj' is deprecated in favor of '$obj.Int'.

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@perl.org mailing list, or ask on IRC #perl6 on freenode.

The next release of Rakudo (#20) is scheduled for August 20, 2009. A list of the other planned release dates and codenames for 2009 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!

More great Perl reading from moritz++

Make better and easier to read announcements

I didn't see this entry in the pending stories. There was an entry for the announcement where half the text was a quote from a book that had apparently no connection to anything other than being clever. That's a stupid thing to do in an announcement, especially when many readers only show the first bits of a post. Always lead with the important bits.

The other half was a plain text bullet list of items. It's a job and a half to reformat that mess for HTML.

There are things that are more important to me then fixing the parrot announcement messes and I've given up on it. Make it easy for me to approve the announcement by taking the time to make a reasonable announcement that is already formatted for HTML.
