Rakudo Star Release 2014.09
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 September 2014 release of "Rakudo Star", a useful and usable distribution of Perl 6. The tarball for the September 2014 release is available from http://rakudo.org/downloads/star/. Windows .MSI versions of Rakudo star for the MoarVM and Parrot backend are also avaiable in the downloads area.
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 (some module tests fail). Two shipped modules are known to fail on Parrot (JSON::RPC and p6doc).
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 2014.09 of the Rakudo Perl 6 compiler, version 6.7.0 of the Parrot Virtual Machine, version 2014.09 of MoarVM, plus various modules, documentation, and other resources collected from the Perl 6 community.
Some of the new features added to this release include:
- panda (the module installer client) does work on windows again
- panda knows about all modules, that are shipped with this release
- ./perl6 --profile for MoarVM
- Workaround OS X make bug for MoarVM
- support for submethod DESTROY (MoarVM only)
- optimizations to Str.words, Str.lines, IO.lines, chomp, and return
- added experimental support for Proc::Async, MoarVM only for now
- Reduced memory size of CORE.setting, improved startup time
- startup (on Moar) 15% faster than p5 w/ Moose
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 for the JVM and MoarVM backend)
- Unicode strings at levels other than codepoints
- interactive readline that understands Unicode
- non-blocking I/O
- 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 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 [email protected].
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 [email protected] mailing list, or join us on IRC #perl6 on freenode.
