| perl6 Perl 6 Summary for 2006-01-24 though 2006-02-07 |
All~
Welcome to another fortnight's summary. I would say more, but my throat really hurts.
Darren Duncan proposed moving the minimum GHS requirement from 6.4.0 to 6.4.1. Based on the conversation, this appears to be a somewhat likely outcome.
Beau E. Cox posted a patch to improve Makefile.PL. Audrey added it and handed him a commit bit.
Pugs, now officially 1 year old, just hit its 6.2.11 release.
Beau E. Cox had trouble linking Pugs 6.2.11 and Parrot 0.4.1. Audrey pointed out that he needed a parrot source tree nearby.
Larry Wall posted an update of S06. It looks very tasty. I hope the standard library has some convenience routines for dealing with Perl 6's AST.
Beau E. Cox was a little confused by Pugs's jump in development version. Kevin Puetz explained the approach to $2 \pi$.
Beau E. Cox, after discovering that a Parrot source tree is necessary to build Pugs, wondered if it was still necessary after Pugs was built. Larry provided the answer: no.
Audrey noticed a problem convincing PGE to alias a scalar. Patrick explained that it was not yet implemented.
Hmmm... If the short one required two cough drops, I fear for the long one. Of course, that was uncharacteristically large for p6l, so perhaps p6i will be short. (Gambler's Fallacy, I know)
Leo noticed a few namespace opcodes which could function either relatively or absolutely. Peoples seemed to want absolute.
Leo posted a few questions about parts of Parrot's guts that he wasn't sure about. Chip posted his thoughts.
Alberto Simões posted his proposal for File/OS functions. Chip provided his opinions as well.
Bob Rogers noticed a change in the semantics of object initialization. He and Leo added tests and nailed down them down more firmly.
Steve Gunnell posted his ideas for how to finalize and improve the I/O filter system on which Parrot's IO is built. Leo, Nicholas Clark, and Joshua Hoblitt fined tuned his ideas slightly.
Ravi Sastry wondered if Parrot could run on z/OS. Jonathan Worthington guessed that it probably would not run right now, but could be made to run by an interested developer.
Jerry Gay noticed that IREGs weren't being zeroed properly.
Norman Nunley found and fixed a bug in Parrot::Configure::Data. Leo applied the patch.
Nicholas Clark noticed some macro strangeness involving PARROT_IN_EXTENSION. Jonathan Worthington determined that it was vestigial and remove it. Nicholas was happy.
Bernhard Schmalhofer noticed that make clean was cleaning itself into a corner.
He filed a bug for it.
Joshua Isom found a problem with the FreeBSD JIT. Leo pointed him to some docs to help him debug his problem.
Joshua Isom posted a patch cleaning up some makefile stuff. Joshua Hoblitt thought that further review was necessary. Warnock applies.
Leo posted a few thoughts on how to support static variables in Parrot. Larry, Nicholas Clark, and Joshua Isom provided a few suggestions.
Allison Randal was having problems with generated PIR code getting truncated. Leo managed to track down and solve the problem.
ankit.momaya@oracle.com posted a job offering to the list. Unfortunately he posted it to google groups (most likely) as it didn't make it to the list proper.
Jonathan Worthington provided a test case display an unexpected interaction between constructors and exceptions. Warnock applies.
Bob Rogers provided a patch allowing Continuations to return values. Leo applied the patch.
Leo noticed that compiling a static parrot leads to problems with dynamic extensions. Nick Glencross tracked it down to a dependency issue with dynamic pmcs.
Recently Bob Rogers suggested restricting the scope of which exception handlers can be cleared by a clear_eh opcode. Leo implemented the request and applied Bob's tests.
*_config.o IssuesFlorian Ragwitz posted a few options on how to clean up the *_config.o issues that seem to come up.
Warnock applies (lightly as he posted on Monday).
Jerry Gay noticed that languages/bc would fail most of its tests without python. It should probably probe for that.
Allison Randal posted a pdf of the parrot repository generated by GraphViz. It is pathological enough that acrobat does not really like the file. I am told that xpdf deals OK.
Will Coleda noticed that r11431 is suddenly failing a few Tcl tests.
Leo tried enabling param count checks to see what would fail. The answer appears to be much. This led to discussion of how to enable and disable checks on both arguments and returns.
François Perrad wondered why his Lua PMCs were failing to find their new methods. Leo explained that the necessary methodhash in them was not yet implemented and gave him a workaround.
Jonathan Lang, Stevan Little, and Rob Kinyon has a discussion about some sort of type casting or coercion in Perl 6. The conversation sorted of petered out undecidedly.
Larry renamed the flip flop operator to ff .
People rejoiced loudly.
Juerd posted his one line perl 5 to perl 6 conversion T-Shirt to cafe press. I know at least one summarizer who would not object to having one show up at his door...
Stevan Little posted a link to a nifty paper on Prototype Based MMD. There is also a short version for the attention impaired. (I read that one; it is neat.)
Dakkar had a few questions about S06. Larry had a few answers.
larry announced that one could put named Unicode code points into strings like this "\c[LATIN CAPITAL LETTER A, COMBINING RING ABOVE]".
goto hell;Larry announced the addition of a goto statement.
Dave Whipp wondered if he could have a variable that was unique to each non-recursive invocation of a function. Luke Palmer suggested that env variables already did this, but Larry pointed out a few nuances there.
Yuval Kogman wants a really powerful sort of automatic application of roles, I think. Warnock applies.
Herbert Snorrason wants more specifics on macros in Perl 6. Larry gave him some.
Yiyi Hu and Andrew Savige found a few typos in a few synopses. Larry graciously fixed them.
Darren Duncan wondered if Perl 6 had a way to provide a default value for uninstantiated variables of a particular type. The led to Larry going into a little more detail on "protype objects", and Matt Fowles pushing for even more detail.
Yuval Kogman posted a loose plan for for improving Perl 6's development momentum. This is a contentious issue, and I will not try to summarize it directly. Read the link, it is the last one of the summary.
