On behalf of the Pugs team, I am delighted to announce the release
of Pugs 6.2.3, with Parrot embedding, Perl 6 Rules support (via PGE),
and an initial sketch of OO system. Multi-thread programming with
async/kill/join/detach is now supported as well.
Also of note are many new, working modules under ext/, some using the
newly supported OO system, some using an inside-out OO system based
on closures.
Pugs is available from a nearby CPAN mirror, or from pugscode.org:
Perl6-Pugs-6.2.3.tar.gz
SIZE = 894640
SHA1 = 16599281a8a103d13e4f0041ccba06bddff28f83
As Pugs now requires Parrot 0.2.0 or later for Rules support,
you may wish to install Parrot first:
parrot-0.2.0.tar.gz
SIZE = 2696634
SHA1 = da4231fda3b7fcb842a886bef3d86d477ecc34e6
Thank to all the lambdacamels for flying with Pugs! :-)
Enjoy,

Changes for 6.2.3 - May 12, 2005
Pugs Internals
-
Pugs can now embed Parrot or use an external parrot executable
- Under embedded mode, Pugs is a registered Parrot compiler
- eval_parrot and require_parrot builtins for running PIR code
- pugs -BParrot can compile Perl 6 program to PIR and run it in-memory
-
Perl 6 Rules support via Parrot/PGE:
- Named rules and subrule support
- The former $0 (entire match) is now $<>
- $0 is now the same as ~$/[0], i.e. the same as Perl 5's $1
- .from, .to, .matches
- //, rx//, m//, rule{}
- s/// and // in statement level operates on $_
-
Basic Object support:
- Accessors generated for public attributes
- Identity operator: =:=
- Method chaining: $foo.bar().baz()
- Method invocants: method foo ($self: $x) and topicalized as $_
- Public and private attributes, as well as has $.attr is rw
- $obj ~~ Class support
- $obj.clone() support
- class Foo {} works (no inheritance yet)
- Experimental eval_yaml() support to parse YAML streams
- Experimental support for prefix reduce metaoperator [+]
- Hyper operators now works on arrays too
- Improved .perl() format for array, hash and pair objects
- Much faster random access to arrays; it's now O(1) instead of O(n)
- Much improved MMD support
- New is lazy trait for parameters
- Refactoring of large Haskell modules to improve compilation speed
- Support for building a profiled Pugs
- Undef in grouped lhs: my ($x, undef, $y) = 1..3; is now legal
- $thread.kill, $thread.detach, $thread.join
- %hash.pick, @array.pick and (list).pick
- reduce primitive
- state $var implemented
- system(Str: List) and exec(Str: List) on Unix platforms
Bundled Modules
- All modules have their own ChangeLog now
- Algorithm::TokenBucket, with closure objects
- Config::Tiny, with closure objects
- Kwid::Event::Parser, with procedures
- Net::IRC, with closure objects
- Perl::MetaModel, prototype of Perl 6 OO meta-model in Perl 6
- Pod::Stream::Parser renamed to Pod::Event::Parser and added more functionality
- Set, with Perl 6 objects
- Test::Builder, with Perl 6 objects (parses, but does not work yet)
- Tree::Simple, with closure objects
Tests, Examples and Documentations
- Many new test and several tests refactored, we now have 4921 tests
- Documentation for hangman.p6 added in examples/games/hangman.pod
- New "Monads in Perl 6" example in examples/functional/monads.p6
- Script to generate a Pugs Live CD in util/livecd
- Several IRC bots added to examples/network including svnbot and logbot
- TODO tests now use :todo<reason> for better reporting
- The first Perl 6 poem in examples/poetry/
Bug Fixes
- Logical short-circuiting operators no longer flattens references
- Prohibit Array and Hash dereference on plain values
- Slurpy context no longer flattens
- Stringifying IO handles is no longer fatal
- $*PID now works on Win32
- %*ENV now completely works on Win32
- (a => 3+4) is now parsed as (a => (3+4)), not (a => 3)+4
- any().pick no longer dies
- my @x = [1]; @x[0][0] = 2 should now work
- next in nested for {} blocks no longer escapes the outer loop
- to => 123 parses again; arrow pairs now always trumps unary functions
- {} in P5 rules is no longer closure interpolation
