Jesse Vincent: Binary data in JSON?

2008-05-06T01:54:56+00:00

JSON doesn't have native support for binary data? Really? Someone, please tell me I'm wrong. (But only if you can back it up with documentation)

Patrick Michaud: Rakudo milestones posted

2008-04-28T18:27:44+00:00

Last week I heard that someone was having trouble finding the Rakudo sources, and it was suggested that blogging about it here might provide an additional pointer. So, if you're looking for the sources to Rakudo Perl, it's currently held in the languages/perl6/ directory of the Parrot repository.

Eventually Rakudo and other languages on Parrot will likely get separate repositories, but for now we all find it easier to keep everything in a single repository.

The architecture and layout of the Rakudo source code is described in docs/compiler_overview.pod. This says what each source file does and how it all fits together.

Also, by popular demand, I've created a list of "milestones" for Rakudo Perl development and stuck them in the ROADMAP. Reproducing the 2008-04-28 version here, we have:

* list context, list assignment
* return and control exceptions
* class, role, objects
* regex, token, rule, grammar
* selected libraries written in Perl 6
* modules
* junctions
* lazy lists
* slices
* multi sub & multi-method dispatch
* captures and signature handling
* operator overloading
* other S09 features (typed arrays, sized types)
* heredocs
* macros
* module versioning

While the milestones roughly in priority sequence, this list isn't meant to be rigid or strictly sequential in nature. If someone wants to work on a later milestone even though we haven't completed the earlier ones, that's certainly okay. This list just gives us a way to see where things are fitting in my head.

Suggestions and additions to the above list are welcome.

Aloha!

On behalf of the Parrot team, I'm proud to announce Parrot 0.6.1
"Bird of Paradise." Parrot (http://parrotcode.org/) is a virtual machine aimed
at running all dynamic languages.

Parrot 0.6.1 can be obtained via CPAN (soon), or follow the
download instructions at http://parrotcode.org/source.html.
For those who would like to develop on Parrot, or help develop
Parrot itself, we recommend using Subversion or SVK on the
source code repository to get the latest and best Parrot code.

Parrot 0.6.1 News:
- Specification
+ drafted pdd29_compiler_tools.pod
+ updated pdd28_character_sets.pod draft
+ updated pdd19_pir.pod draft
- Languages
+ c99: added independent C pre-processor
+ HQ9+: reimplemented with PCT
+ Lua:
. reimplementation with PCT, using PAST and POST
. behavior aligned wih 5.1.3
+ Rakudo:
. implemented basic I/O, including '$*IN', '$*OUT', '$*ERR', 'prefix:='
. implemented simple typing and runtime type checking
. added basic multi-method dispatch
. expanded named argument handling, including Pair and colonpairs
. added 'Whatever' and 'Capture' classes

. added 'postfix:++', 'postfix:--' operators
+ PCT:
. added methods specifying default behaviors in PAST, reducing repeated code
. improved symbol table lookup
+ PGE:
. removed deprecated code including: P6Regex, P6Grammar, PAST-pm
- Miscellaneous
+ notable speedups during compilation and execution of parrot and HLLs
+ pdb (the parrot debugger) can now catch parrot exceptions
+ better detection of glibc and gettext during configuration
+ various bugfixes, code cleanups, deprecations, and coding standard fixes

Mahalo to all our contributors for making this possible, and our
