The tarball for the February 2012 -release is available from <http://github.com/rakudo/star/downloads>. - -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 #49 of the -Rakudo Perl 6 compiler [1], version 4.1 of the Parrot Virtual -Machine [2], and various modules, documentation, and other -resources collected from the Perl 6 community. - -Here are some of the major improvements in this release over the -previous distribution release. - -* The FatRat type is implemented, and Rat arithmetic now properly - defaults to Num if the denominator is too big - -* Object hashes are implemented, and can be declared with the syntax - my %h{Any} (for a hash with keys of type Any) - -* The <Some::Grammar::rulename> syntax is now implemented in regexes; - <foo> can also be used to call predeclared lexical rules - -* The Int($x) coercion syntax is implemented - -* &rename and © are now implemented - -* Improvements to the reduction meta-operator (order of magnitude faster, - some parsing issues fixed) - -* The <prior> regex built-in is now available, and matches whatever the - last successful match matched - -* A $match.make(...) method is available to set the AST for a match - object not stored in the $/ variable - -* Improved backtraces - -This release also contains a range of bug fixes, improvements to error -reporting and better failure modes. Many more exceptions are thrown -as typed exceptions. - -Due to continued evolution of and convergence with the Perl 6 spec, there -are some changes to existing functionality that may affect your code: - -* You may no longer use the $.x form in submethods and attribute - initializers, as per spec; use the non-virtual $!x instead. - -* The LHS of the xx operator is now thunked - -* .conjugate is now called .conj - -* Enumeration values .gist to just the key, not the full name - -* An empty Buf is now False in boolean context - -Currently, we have maintained backwards compatibility with some -changed pieces of syntax, but will drop them in an upcoming release: - -* "<...>" in proto regex bodies; now this should be written "*" - -* The use of "**" with a separator in regexes; this is now done by - using "%" or "%%" on another quantifier - -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: - * pack and unpack - * macros - * threads and concurrency - * Unicode strings at levels other than codepoints - * pre and post constraints, and some other phasers - * interactive readline that understands Unicode - * non-blocking I/O - * much of Synopsis 9 - -There is a new online resource at http://perl6.org/compilers/features -that lists the known implemented and missing features of Rakudo Star -2012.02 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. -An updated 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. - -[1] http://github.com/rakudo/rakudo -[2] http://parrot.org/ |
