Perl 6 mailing list summary for the month of June, 2006

     This post continues with the task of addressing the Perl 6 summary backlog.
     The following schedule is planned for the remaining updates:

     * 13 August: July
     * 20 August: August to date

     After the 20th of August I hope to return the summaries to a weekly

   class introspection and extension <http://xrl.us/qc4r>

     Max Demmelbauer is in the process of porting his web-framework project to
     Perl6 had had a question on how he could serialize objects and extend a
     class. Thomas Wittek offered an example of syntax and gave links to the
     documents the information was derived from. Conrad Schneiker noted that he
     and other people on the #perl6 IRC channel would be happy to help if the
     mailing list didn't yield answers.

   Conditionally included list elements <http://xrl.us/qc4s>

     A. Pagaltzis asked if Perl 6 has a construct to express conditionally
     included list elements, which require several steps in Perl 5. A couple of
     people responded with suggestions.

Parrot 0.4.6 Released!

On behalf of the Parrot team, I'm proud to announce Parrot 0.4.6, the most
recent close-to-monthly release of Parrot.  I'm particularly pleased to
report that Parrot 0.4.6 includes the beginnings of a Ruby implementation
(named "Cardinal"), thanks to the work of Kevin Tew.

What is Parrot?  Parrot is a virtual machine aimed at running all dynamic
languages.  The Parrot project home page is <http://www.parrotcode.org/>.

You may now grab Parrot 0.4.6 from:

  <http://www.cpan.org/authors/id/CHIPS/parrot-0.4.6.tar.gz>

New in Parrot 0.4.6:

  - New languages: Ruby ("Cardinal"), Javascript ("ecmascript")
  - Updated languages: Tcl, dotnet, bc, Pheme, Punie, WMLScript
  - Updated compilers: PGE, TGE
  - IMCC updates:
     + ".loadlib" directive expresses dependencies
     + ".namespace" with no parameter goes to HLL root
     + lexer is reentrant (reentrant grammar in progress)
  - Namespace improvements:
     + new suite of opcodes to access namespaces and globals
       ("find_global" and "store_global" will be phased out)
     + namespace '' no longer means HLL root
  - Design document updates:
      namespaces (pdd23), basic types (pdd17), embedding
  - Updated tool requirements for developers:
      flex 2.5.33, bison 2.1, perl 5.6.1
  - New to-do list for people new to Parrot:

Perl 6 mailing list summary for the month of July, 2006

Perl 6 mailing list summary for the month of July, 2006

    Summary updates

     This post continues to work on the Perl 6 summary backlog. After the
     upcoming August 20th recapitulation of the first three weeks of August,
     Perl 6 summaries will return to a weekly schedule.

   RFF: test Emacs Perl6 mode <http://xrl.us/qoaf>

     Steffen Schwigon invited anyone who uses (X)Emacs to work with Perl6 or
     Pugs to give feedback on the enhanced cperl-mode at <http://xrl.us/qnxz>

   [ANNOUNCE] Pugs 6.2.12 and v6.pm released! (reformatted) <http://xrl.us/qnx2>

     Audrey Tang wrote that Pugs 6.2.12 is available on CPAN, and listed some of
     the key features. v6.pm, a prototype Perl 6 compiler implemented in Perl 5
     is also available on CPAN. She highlighted a number of modules which had
     contributed toward the solution, such as Moose and Module::Compile.

   Your ideas/preferences for Perl 6 IDE, RCP, Acme-like shell, and so on?
   <http://xrl.us/qnx3>

     Conrad Schneiker had several questions for the group: what key features
     should be in a FOSS tool suite involving Perl 6, what major existing
     components are recommended, and how people would design it to take
     advantage of new Perl 6 capabilities.

Perl 6 mailing list summary for the weeks of August 1-19, 2006

Perl 6 mailing list summary for the weeks of August 1-19, 2006

  Summary updates

     This is the final installment of the older summaries. After this week, I
     plan to post weekly summaries on Sundays.

  Parrot Porters

   [perl #39750] parrot <at> 13183: tru64 core dump: t/examples/japh_12.pasm
   <http://xrl.us/qvh3>

     This thread was previously completely summarized in July.

     In [perl #39750] <http://xrl.us/qvh5>, Jarkko Hietaniemi posted about a
     core dump. Chip Salzenberg fixed it.

   [perl #39751] unbug - parrot <at> 13183: tru64 core dump: t/dynoplibs/myops_4.pir
   <http://xrl.us/qvh6>

     This thread was previously completely summarized in July.

     In [perl #39750] <http://xrl.us/qvh5>, Jarkko Hietaniemi posted about a
     core dump. Will Coleda replied that this is how the test should behave, and
     wondered if the test should be skipped or the opcode removed. Chip
     Salzenberg wrote a haiku about the test, and Jarkko poetically requested
     that the test harness be informed about Parrot's tendency to obey suicide
     requests.

Ponie has been put out to pasture

Over the past several years, one key aspect of the migration plan to  
Perl 6 has been the Ponie project, a fusion of the Perl 5 runtime  
with Parrot. Sponsored by Fotango, Artur Bergman and Nicholas Clark  
did a heroic job cleaning up Perl's internals to make it possible to  
replace some components of Perl 5 with Parrot, one piece at a time,  
while still keeping the core of the Perl 5 runtime intact with 100%  
bug-for-bug compatibility. Along the way, Nicholas ported several  
significant Perl core improvements from Ponie back to the Perl 5.9 tree.

Ponie never really became a community project. All significant work  
was done as part of Fotango's sponsorship. When it had good momentum  
and sponsored developers, it needed a number of Parrot features that  
weren't yet available. At this point, Ponie has not been in active  
development for almost half a year and it's my unhappy duty to  
declare the project dead.

Norman Nunley is currently working to do a final extraction of  
unharvested improvements from the Ponie code before we put it out to  
pasture. Lots of good came out of Ponie, just not the good things we  
expected.

A number of very talented hackers are currently exploring multiple  
strategies to enable most Perl 5 code to run seamlessly along side  
Perl 6 in Parrot. Folks have already demonstrated a proof-of-concept  
Parrot VM embedded in the Perl 5 runtime. Work is underway on a Perl  
5 to Perl 6 translator and the existing Perl 6 compiler on Parrot is  
the proof of concept for a similar implementation of a "regularized"  
Perl 5. At this point, it wouldn't be reasonable to bless any one  
right way forward but each of these techniques (and possibly others)  
could play a part in whatever "5 on 6" scheme we end up with. No

Weekly Perl 6 mailing list summary for August 20-26, 2006

  This week on the Perl 6 mailing lists

     "My school's punch card machines were in the same room as the TRS-80
     Model I ("THE COMPUTER ROOM"). These kids today with their hula hoops
     and fax machines and intarwebs..."

     -- Chip Salzenberg, arguing in *favor* of lines in excess of
     80-characters.

  perl6-language

   multi-line comments, C macros, & Pod abuse <http://xrl.us/qyci>

     Last week's summary covered this thread, which discussed easily
     commenting out a large chunk of code.

     This week the discussion continued slightly in to the realm of
     meta-programming and programming environments, but not much meat was
     added.

   clarify: does "Dog is Mammal" load Mammal for you? <http://xrl.us/q5ge>

     Mark Stosberg asked for clarification on S12 on whether `class Dog is
     Mammal` requires Mammal to be loaded in advance. The current version
     of Pugs needs an explicit `use Mammal`.

     Darren Duncan believed an implicit `use Mammal` should only occur
     conditionally, if a Mammal had been declared, but was concerned about
     potential bugs. Jonathan Scott Duff had the impression that preloading
     would not be required, and wondered if `class Dog is Mammal-4.5` would
