Announce: Rakudo Perl 6 development release #20 ("PDX")
On behalf of the Rakudo development team, I'm pleased to announce
the August 2009 development release of Rakudo Perl #20 "PDX".
Rakudo is an implementation of Perl 6 on the Parrot Virtual Machine [1].
The tarball for the August 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. August 2009 is code named "PDX" for the
Portland Perl Mongers. PDX.pm has been home to several Rakudo
contributors (chromatic, Allison Randal, and more) and PDX.pm has
held meetings that have produced feature and bugfix patches for Rakudo.
Beginning with this release, Rakudo Perl now builds itself from an
"installed Parrot" instead of using Parrot's build tree. This
release of Rakudo requires Parrot 1.5.0. See the "Building and
invoking Rakudo" section of the README file for the latest
information on building and using Rakudo Perl. (Quick note:
the "--gen-parrot" option still automatically downloads and
builds Parrot as before, if you prefer that approach.)
Also, unlike previous versions of Rakudo Perl, the "perl6"
(or "perl6.exe") binaries will only work when run from the
Rakudo root directory until a "make install" is performed.
The "make install" target installs Rakudo into the appropriate
locations provided by the installed Parrot that was used to build
Rakudo. Once this is done, the executables can be run from
any directory.
Some of the specific major changes and improvements occuring
with this release include:
* Rakudo is now passing 12,369 spectests, an increase of 493
passing tests since the July 2009 release. With this release
Rakudo is now passing 69.9% of the available spectest suite.
* User defined traits can now be applied to classes and roles.
* The 'hides' trait on classes can make one class hide another.
* Many not-yet-implemented operators and features now provide
more helpful error messages instead of simply producing
parse errors.
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 (#21) is scheduled for September 17, 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!
