Perl 6 Summary for 2005-09-26 through 2005-10-02
All~
Welcome to another summary, this time a day late because I was in Philly
for Serenity. If you haven't seen Serenity yet you should stop reading
this summary and go see it. The summary will be here when you get back.
I promise.
Perl 6 Compiler
No postings this week. I blame Piers for scaring them off last week.
Parrot
Summary Links
Last weeks load lib thread morphed into a conversation about the life
span of the shortened links that appear in summaries. Piers pointed out
that, although the short links expire, the long links are archived at
perl.org.

RT Cleanup
Joshua Hoblitt has been continuing his massive clean up of RT. It makes
me glad of two things: that someone is doing it and that I am not doing
it. I won't post all of the links for these messages, but much work is
getting done.
debug segments
Jonathan Worthington posted an RFC of his design for debug and source
segments in Parrot's packfiles. People seem to like it generally.
Hopefully the design will be implemented soon.

Leo's Context Branch Hits the Mainline
After a few more reviews from Chip, Leo's context branch has been dubbed
ready and has been moved to the mainline. This marks the culmination of
quite a bit of hard work from many people (especially Leo). Nice work
all.
<http://xrl.us/hvbp> -- bit of review
<http://xrl.us/hvbq> -- merge
Amber PMCs
Roger Browne wondered how he should include Amber PMCs. Leo and Will
suggested he put the pmcs into the languages directory similar to the
way Tcl does it.
<http://xrl.us/hvbr>
Data::Escape Needs Tests
Jerry Gay added a TODO for tests for Data::Escape. This would be a great
thing for an eager lurker to cut his or her teeth on.
<http://xrl.us/hvbs>
Magic Numbers Bad, Magic Strings Good
Last weeks magic thread ended down with the conclusion that Parrot would
use a magic string instead of a magic number.
<http://xrl.us/hvbt>
Tests fail on win32
Jerry Gay opened a new RT ticket for some failing tests on Windows.
<http://xrl.us/hvbu>
Here Doc in PIR
Will Coleda revived a thread from February about PIR here doc syntax.
Looks like the syntax is ok.
<http://xrl.us/hvbv>
Win32 PCRE
François Perrad enabled PCRE on Win32. Jerry Gay applied the patch.
<http://xrl.us/hvbw>
PLATFORMS and MinGW
François Perrad updated the PLATFORMS file for MinGW.
<http://xrl.us/hvbx>
parrot_config dependency
Nick Glencross provided a patch (for comment only) that eases the
dependency on parrot_config. I am not sure that he got many comments.
<http://xrl.us/hvby>
Data::Escape::String Dislikes Unicode
Will noticed that Data::Escape::String doesn't work on Unicode strings.
<http://xrl.us/hvbz>
Make Cleanup
Joshua Hoblitt started RT tickets for several things that are part of a
general make system clean up.
<http://xrl.us/hvb2>
<http://xrl.us/hvb3>
<http://xrl.us/hvb4>
Parrot Leaves Crumbs
Nick Glencross rediscovered the core files that parrot leaves around.
This is a known problem.
<http://xrl.us/hvb5>
Parrot Threads
Dave Frost wondered what the plan for Parrot Threading was going to be.
The answer (provided by Leo with more details from Jonathan Worthington)
was OS threads.
<http://xrl.us/hvb6>
Once deprecation's lost its fun...
Leo went on a bit of fall cleaning adding things to the deprecated list.
He even threatened to resolve some of them soon.
<http://xrl.us/hvb7>
<http://xrl.us/hvb8>
<http://xrl.us/hvb9>
<http://xrl.us/hvca>
Lexical and Variable Sized Register Frames
With the calling conventions having been redone, Leo has plans to move
to system of dynamically sized registers frames with static lexicals
stored directly in them. Chip should produce details soon.
<http://xrl.us/hvcb>
Exception Handling Bug
Roger Browne found a bug with exception handlers in the new scheme. Leo
fixed it. I wonder if anyone made a test out of it...
<http://xrl.us/hvcc>
Config missing output
Will Coleda noticed that Configure.pl was not outputting a response to a
step on his platform.
<http://xrl.us/hvcd>
Parrot 0.3.0 TODO
Robert J Eaglestone wondered what would be a good way of chipping in.
Will Coleda, predictably, tried to turn him towards working for the good
of Tcl.
<http://xrl.us/hvce>
Tru64 Issues
Jarkko Hietaniemi appears to have recently come into some time with a
Tru64 machine. He found lots of problems, which he added to RT, so I
won't link them here.
src/extends.c
chromatic made good on a promise to auto generate src/extends.c
automatically. Leo quibbled over pod, but thought it was good.
<http://xrl.us/hvcf>
Calling Vtable Functions from PIR
Roger Browne found he can no longer call vtable functions from PIR
directly. Leo felt that it was no longer necessary,
<http://xrl.us/hvcg>
registers don't start zeroed.
Jerry Gay found a test that was failing. Leo pointed out that I and N
register no longer start zeroed, so the test should manually NULL them
first.
<http://xrl.us/hvch>
Tcl Compiling
Will Coleda has not beaten his Tcl interpreter into the starts of a
compiler. It looks quite cool and progress is on going.
<http://xrl.us/hvci>
BROKEN.pod
chromatic has plans to add a broken.pod file to the root of parrot
detailing things that need love. Joshua Hoblitt thought that it should
be split up into RT tickets. Leo suggested one be auto generated from
the other. I like that idea.
<http://xrl.us/hvcj>
Parrot gobbles up memory
Andy Dougherty noticed that parrot was eating up memory. He managed to
trace the problem to a pointer aliasing issue. Leo suggested that this
was probably cause by a casting macro that needed some loving.
<http://xrl.us/hvck>
Software Architecture of Parrot
Klaas-Jan Stol announced his intent to write a paper on the current
architecture of Parrot for a CS course. He also asked for help with
editing to eliminate inaccuracies.
<http://xrl.us/hvcm>
Perl 6 Language
stringimification
Last weeks stringimification thread wound down early this week with the
[second hand] declaration from Larry that things would stringimify the
same as they interpolate.
<http://xrl.us/hvcn>
<http://xrl.us/hvco>
Stringification, numification, and booleanification of pairs
.thingies in different context
Juerd posted a fairly thorough explanation of how .thingies (like .chars
and .elems) can be made to DWIM most of the time. Warnock applies.
<http://xrl.us/hvcp>
"Do It Once" Feature
Last week's thread about a "Do it once" feature morphed turned to flip
flop operators for a way to implement it.
<http://xrl.us/hvcq>
Perl 6 Polyglot
Geoffrey Broadwell posted a link to his O'Reilly blog article "Perl 6
Polyglot".
<http://www.oreillynet.com/pub/wlg/7928> <http://xrl.us/hvcr>
"\&"
Ruud H.G. van Tol wondered about using \& (which means the whole match
in sed) in Perl 6. Larry announced that $<> would serve this purpose.
<http://xrl.us/hvcs>
Look ahead/behind for loops
Dave Whipp wondered about having for loops with look ahead and look
behind arguments. The idea has mixed review with Damian being fairly
vocally opposed.
<http://xrl.us/hvct>
<http://xrl.us/hvcu>
Exceptuations
As Piers predicted Exceptuations are still Exceptuating.
<http://xrl.us/hvcv>
<http://xrl.us/hvcw>
Seeing the Light
David Storrs sees the light at the end of the tunnel for Perl 6.
Hopefully that doesn't mean it is dead.
<http://xrl.us/hvcx>
When to Stop Zipping
Juerd wondered exactly when zip stops when given lists of differing
length. No official answer yet.
