## A useful, usable, early adopter distribution of Perl 6
On behalf of the Rakudo and Perl 6 development teams, I'm happy to
announce the March 2015 release of Rakudo Star, a useful and usable
distribution of Perl 6. The tarball for the March 2015 release is
available from http://rakudo.org/downloads/star/.
This Rakudo Star release comes with support for the MoarVM
backend (all module tests pass on supported platforms) along with
experimental support for the JVM backend (the modules `Bailador`,
`Digest::MD5` and `Grammar::Profiler::Simple` are known to fail tests).
In the Perl 6 world, we make a distinction between the language
(Perl 6) and specific implementations of the language such as
Rakudo Perl. This Star release includes [release 2015.03] of the
[Rakudo Perl 6 compiler], version 2015.03 of [MoarVM], plus various
modules, documentation, and other resources collected from the
Perl 6 community.
[release 2015.03]:
https://github.com/rakudo/rakudo/blob/nom/docs/announce/2015.03.md
[Rakudo Perl 6 compiler]: http://github.com/rakudo/rakudo
[MoarVM]: http://moarvm.org/
Some of the new compiler features added to this release include:
+ several renames of semi-internal methods. Please refer to [the Rakudo
2015.02 release
notes](https://github.com/rakudo/rakudo/blob/nom/docs/announce/2015.03.md)
for the full list
+ Allow `Buf.AT-POS` to return an l-value.
+ Implement `method ^foo($) { ... }` syntax.
+ Implemented [PairMap](http://doc.perl6.org/type/PairMap) (the simple
case only, for now).
+ Implemented `.antipairs` (pairs with value = key).
+ Implemented [pairup](http://doc.perl6.org/type/Any#method_pairup)
for creating pairs from lists.
+ Implemented `LEXICAL`, `OUTERS` and `CALLERS` pseudo-packages
+ Add `array[T]`, usable for native `int`/`num` (MoarVM only for now)
+ Other native improvements, e.g. `my int $a; $a++`
+ Implement `IO::Path.resolve` on r-m/POSIX
In future, the `nqp::` namespace willl only be available after a
declaration
like `use nqp;`.
Changes to modules included in Rakudo Star:
- - [DBIish](https://github.com/perl6/DBIish) supports local Sockets on
mysql,
and now correctly handles returned NULL values in the Pg backend
- - [doc](https://github.com/perl6/doc) ships with much more documentation
There are some key features of Perl 6 that Rakudo Star does not yet
handle appropriately, although they will appear in upcoming releases.
Some of the not-quite-there features include:
* advanced macros
* threads and concurrency (in progress)
* Unicode strings at levels other than codepoints
* interactive readline that understands Unicode
* non-blocking I/O (in progress)
* much of Synopsis 9 and 11
There is an online resource at http://perl6.org/compilers/features
that lists the known implemented and missing features of Rakudo's
backends and other Perl 6 implementations.
In many places we've tried to make Rakudo smart enough to inform the
programmer that a given feature isn't implemented, but there are many
that we've missed. Bug reports about missing and broken features are
welcomed at rakudo...@perl.org.
See http://perl6.org/ for links to much more information about
Perl 6, including documentation, example code, tutorials, reference
materials, specification documents, and other supporting resources. A
draft of a Perl 6 book is available as docs/UsingPerl6-draft.pdf in
the release tarball.
The development team thanks all of the contributors and sponsors for
making Rakudo Star possible. If you would like to contribute, see
http://rakudo.org/how-to-help, ask on the perl6-compi...@perl.org
mailing list, or join us on IRC \#perl6 on freenode.
