Announce: Windows MSI Installers for release 2015.03

MSI installers now come in two versions.

In the past we had to build Rakudo on a x86 (32bit) platform to create an MSI installer package that is most portable. As of now we will also provide an x86_64 (64bit) installer package that additionally comes with JIT support.
If you have a 64bit system, probably Windows 7 or newer, the x86_64 version should give an extra performance boost compared to the 32bit version.
The two MSIs are available from http://rakudo.org/downloads/star/.

Announce: Rakudo Star Release 2015.03

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.

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
    for the full list
  • Allow Buf.AT-POS to return an l-value.
  • Implement method ^foo($) { ... } syntax.
  • Implemented PairMap (the simple case only, for now).
  • Implemented .antipairs (pairs with value => key).
  • Implemented 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 supports local Sockets on mysql,
    and now correctly handles returned NULL values in the Pg backend
  • 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 rakudobug@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-compiler@perl.org
mailing list, or join us on IRC #perl6 on freenode.

Announce: Rakudo Star Release 2015.02

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 February 2015 release of “Rakudo Star”, a useful and usable
distribution of Perl 6. The tarball for the February 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 (some module tests fail).
One shipped module is known to fail on Parrot (jsonrpc).

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 2015.02 of the
Rakudo Perl 6 compiler, version 6.10.0 of the Parrot Virtual
Machine
, version 2015.02 of MoarVM, plus various modules,
documentation, and other resources collected from the Perl 6
community.

https://github.com/rakudo/rakudo/blob/nom/docs/announce/2015.02.md

Some of the new compiler features added to this release include:

  • On MoarVM, symlinks are now followed. This means that e.g. a given path
    can have both .l and .d be true, if the symlink points to a directory.
    This behaviour now matches the behaviour on the Parrot and JVM backend,
    therefore one could consider this a bug fix, rather than an incompatible
    change.
  • Overriding invoke/postcircumfix:<( )> for type coercions (ex. MyType(...))
    now passes the function arguments as-is, rather than just passing a Capture
    containing them. To get the old behavior, simply declare a Capture
    parameter (|c).
  • 6; at unit start is no longer a way to say no strict;. It was deemed
    to be a bad meme and huffmannized inappropriately.
  • Coercion syntax now works in signatures: sub foo(Str(Any) $a) { ... }
    will take Any value as its first positional parameter, and coerce it to
    Str before making it available in $a. Note that Str(Any) can be shortened
    to Str().
  • sub MAIN; (as in, rest of file is the MAIN unit) has been implemented.
  • Metaop = now respects the precedence of the op it is meta-ing.
  • Many optimizations, improved error messages and bugs fixed (over
    200 commits to Rakudo since the 2015.01 release).

In future, the nqp:: namespace willl only be available after a declaration
like use nqp;.

Changes to modules included in Rakudo Star:

  • JSON::Tiny gives better error messages on invalid input
  • panda gives better error messages when
    projects.json is not a valid JSON file (for example due to ISP-level HTTP filtering)
  • doc ships with much more documentation
  • LWP::Simple supports PUT and HEAD requests,
    as well as TLS if IO::Socket::SSL is installed.

The Math::Model and Math::RungeKutta modules no longer ship with Rakudo
Star. They can still be installed with panda.

This is the last Rakudo Star release with support for the Parrot backend,
until volunteers are found that bring the Parrot backend in shape and on par with
the other backends, and implement necessary features for upcoming changes. See
this blog post for
more information.

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 (in progress for the JVM and MoarVM backend)

Announce: Rakudo Star Release 2015.01

On behalf of the Rakudo and Perl 6 development teams, I’m happy to announce the January 2015 release of “Rakudo Star”, a useful and usable distribution of Perl 6. The tarball for the January 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 (some module tests fail). Three shipped modules are known to fail on Parrot (zavolaj (NativeCall), jsonrpc and doc)

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 2015.01.1 of the Rakudo Perl 6 compiler, version 7.0.1 of the Parrot Virtual Machine, version 2015.01 of MoarVM, plus various modules, documentation, and other resources collected from the Perl 6 community.

Some of the new compiler features added to this release include:

  • Many improvements to Java interop for the JVM backend
  • New simple way of creating an object hash: :{}
  • Substitution now supports assignment meta-op, e.g. s[\d+] += 2
  • Many memory and CPU optimizations
  • Supply.for deprecated in favour of Supply.from-list

Changes to modules included in Rakudo Star:

  • Bailador handles POST and URL params separately
  • DBIish has improved error reporting on SQLite
  • doc ships with much more documentation
  • panda has a new command installdeps
  • Pod::To::HTML now supports callbacks for code areas

Parrot support will likely be suspended or dropped from future Rakudo and Rakudo Star releases, starting with the February or March releases.

In the next Rakudo Star release, modules Math::RungeKutta and Math::Model will likely be dropped. They can still be installed with panda.

In future, the nqp:: namespace willl only be available after a declaration like `use nqp;’.

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:

Rakudo Star Release 2014.03

Announce: Rakudo Star Release 2014.03

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 2014 release of “Rakudo Star”, a useful and usable
distribution of Perl 6. The tarball for the March 2014 release is
available from http://rakudo.org/downloads/star/. A Windows .MSI
version of Rakudo star is also available at that location.

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 2014.03] of the
[Rakudo Perl 6 compiler], version 6.1.0 of the [Parrot Virtual
Machine], plus various modules, documentation, and other resources
collected from the Perl 6 community.

[release 2014.03]:
https://github.com/rakudo/rakudo/blob/nom/docs/announce/2014.03.md
[Rakudo Perl 6 compiler]: http://github.com/rakudo/rakudo
[Parrot Virtual Machine]: http://parrot.org

Some of the new features added to this release include:

  • The core of Rakudo::Debugger is now part of Rakudo itself and works across all backends.
  • “make” no longer itemizes its arguments.
  • for-loops at the statementlist level are now sunk by default.
  • better parsing of unspaces and formatting codes inside Pod blocks.
  • Fix for for-loops to be properly lazy
  • Numerous Pod parsing and formatting improvements
  • @ as shortcut for @$, % as shortcut for %$
  • list infix reductions no longer flatten
  • Numerous compiler suggestion improvements

Please note that this release of Rakudo Star does not support the JVM
nor the MoarVM backends from the Rakudo compiler. While the other backends
mostly implement the same features as the Parrot backend, some bits are
still missing that lead to module build problems or test failures.
We hope to provide experimental JVM-based and MoarVM-based Rakudo Star
releases in April 2014.

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 work 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 rakudobug@perl.org.

See http://perl6.org/ for links to much more information about
Perl 6, including documentation, example code, tutorials, reference

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
