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.

groups.google.com#4e48a3cb1e0823ad -- bit of review

groups.google.com#02126e9825ca5acb -- 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.

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.

groups.google.com#29431cfd0a679f83

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.

Tests fail on win32

Jerry Gay opened a new RT ticket for some failing tests on Windows.

Here Doc in PIR

Will Coleda revived a thread from February about PIR here doc syntax. Looks like the syntax is ok.

groups.google.com#74ac0efba45bf279

Win32 PCRE

Fran\xE7ois Perrad enabled PCRE on Win32. Jerry Gay applied the patch.

groups.google.com#25edfe4870252196

PLATFORMS and MinGW

Fran\xE7ois Perrad updated the PLATFORMS file for MinGW.

groups.google.com#5824e7f69dd21491

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.

Data::Escape::String Dislikes Unicode

Will noticed that Data::Escape::String doesn't work on Unicode strings.

Make Cleanup

Joshua Hoblitt started RT tickets for several things that are part of a general make system clean up.

Parrot Leaves Crumbs

Nick Glencross rediscovered the core files that parrot leaves around. This is a known problem.

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.

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.

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.

groups.google.com#50cedfe5ebc4c576

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...

groups.google.com#eb5282688fa5b51e

Config missing output

Will Coleda noticed that Configure.pl was not outputting a response to a step on his platform.

groups.google.com#bfaacb177ae934be

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.

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.

groups.google.com#14889d7380836170

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,

groups.google.com#62cd64deaa7f1d2e

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.

groups.google.com#87fa61cf21499592

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.

groups.google.com#898b5a02d6773cc0

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.

groups.google.com#cfbd149e4efb8d82

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.

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.

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.

groups.google.com#85e3bfb37b62da55

groups.google.com#0d7dcd239960b625

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.

"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.

Perl 6 Polyglot

Geoffrey Broadwell posted a link to his O'Reilly blog article "Perl 6 Polyglot".

\&

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.

groups.google.com#bfc5139fef883c91

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.

Exceptuations

As Piers predicted Exceptuations are still Exceptuating.

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.

groups.google.com#df80856fc3a05617

When to Stop Zipping

Juerd wondered exactly when zip stops when given lists of differing length. No official answer yet.
