| perl6 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.
No postings this week. I blame Piers for scaring them off last week.
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.
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.
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.
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://groups.google.com/group/perl.perl6.internals/browse_frm/thread/ef44dd464ae971dd/4e48a3cb1e0823ad#4e48a3cb1e0823ad -- bit of review
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.
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.
Last weeks magic thread ended down with the conclusion that Parrot would use a magic string instead of a magic number.
Jerry Gay opened a new RT ticket for some failing tests on Windows.
Will Coleda revived a thread from February about PIR here doc syntax. Looks like the syntax is ok.
François Perrad enabled PCRE on Win32. Jerry Gay applied the patch.
François Perrad updated the PLATFORMS file for MinGW.
Nick Glencross provided a patch (for comment only) that eases the dependency on parrot_config. I am not sure that he got many comments.
Will noticed that Data::Escape::String doesn't work on Unicode strings.
Joshua Hoblitt started RT tickets for several things that are part of a general make system clean up.
Nick Glencross rediscovered the core files that parrot leaves around. This is a known problem.
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.
Leo went on a bit of fall cleaning adding things to the deprecated list. He even threatened to resolve some of them soon.
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.
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...
Will Coleda noticed that Configure.pl was not outputting a response to a step on his platform.
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.
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.
chromatic made good on a promise to auto generate src/extends.c automatically. Leo quibbled over pod, but thought it was good.
Roger Browne found he can no longer call vtable functions from PIR directly. Leo felt that it was no longer necessary,
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.
Will Coleda has not beaten his Tcl interpreter into the starts of a compiler. It looks quite cool and progress is on going.
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.
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.
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.
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.
Stringification, numification, and booleanification of pairs
Juerd posted a fairly thorough explanation of how .thingies (like .chars and .elems) can be made to DWIM most of the time. Warnock applies.
Last week's thread about a "Do it once" feature morphed turned to flip flop operators for a way to implement it.
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.
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.
As Piers predicted Exceptuations are still Exceptuating.
David Storrs sees the light at the end of the tunnel for Perl 6. Hopefully that doesn't mean it is dead.
Juerd wondered exactly when zip stops when given lists of differing length. No official answer yet.
