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.
Perl 6 Language
Pugs's Minimum GHC
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.
<http://xrl.us/jws4>
Pugs Makefile.PL Update
Beau E. Cox posted a patch to improve Makefile.PL. Audrey added it and
handed him a commit bit.
<http://xrl.us/jws5>
Pugs 3.2.11
Pugs, now officially 1 year old, just hit its 6.2.11 release.
<http://xrl.us/jws6>
Pugs Link Error
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.
<http://xrl.us/jws7>
Macros
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.
<http://xrl.us/jws8>
Pugs Version Numbers
Beau E. Cox was a little confused by Pugs's jump in development version.
Kevin Puetz explained the approach to $2 \pi$.
<http://xrl.us/jws9>
Parrot Source Tree for Pugs?
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.
<http://xrl.us/jwta>
PGE Binding
Audrey noticed a problem convincing PGE to alias a scalar. Patrick
explained that it was not yet implemented.
<http://xrl.us/jwtb>
Parrot
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)
Namespace Relativism
Leo noticed a few namespace opcodes which could function either
relatively or absolutely. Peoples seemed to want absolute.
<http://xrl.us/jwtc>
Interpreters and Stashes?
Leo posted a few questions about parts of Parrot's guts that he wasn't
sure about. Chip posted his thoughts.
<http://xrl.us/jwtd>
File, OS, and Path
Alberto Simões posted his proposal for File/OS functions. Chip provided
his opinions as well.
<http://xrl.us/jwte>
Object Initialization Issues
Bob Rogers noticed a change in the semantics of object initialization.
He and Leo added tests and nailed down them down more firmly.
<http://xrl.us/jwtf>
I/O Filters
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.
<http://xrl.us/jwtg>
Parrot on z/OS
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.
<http://xrl.us/jwth>
Dirty I Registers
Jerry Gay noticed that IREGs weren't being zeroed properly.
<http://xrl.us/jwti>
Parrot::Configure::Data::Bug
Norman Nunley found and fixed a bug in Parrot::Configure::Data. Leo
applied the patch.
<http://xrl.us/jwtj>
PARROT_IN_EXTENSION
Nicholas Clark noticed some macro strangeness involving
PARROT_IN_EXTENSION. Jonathan Worthington determined that it was
vestigial and remove it. Nicholas was happy.
<http://xrl.us/jwtk>
Invalid Cleaning Order
Bernhard Schmalhofer noticed that "make clean" was cleaning itself into
a corner. He filed a bug for it.
<http://xrl.us/jwtm>
FreeBSD JIT Bug
Joshua Isom found a problem with the FreeBSD JIT. Leo pointed him to
some docs to help him debug his problem.
<http://xrl.us/jwtn>
Makefile Cleanup
Joshua Isom posted a patch cleaning up some makefile stuff. Joshua
Hoblitt thought that further review was necessary. Warnock applies.
<http://xrl.us/jwto>
Supporting Static Variables
Leo posted a few thoughts on how to support static variables in Parrot.
Larry, Nicholas Clark, and Joshua Isom provided a few suggestions.
<http://xrl.us/jwtp>
Truncating Generated PIR Code
Allison Randal was having problems with generated PIR code getting
truncated. Leo managed to track down and solve the problem.
<http://xrl.us/jwtq>
Want a Job?
[EMAIL PROTECTED] 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.
<http://xrl.us/jwtr>
Exception in a Constructor Oddness
Jonathan Worthington provided a test case display an unexpected
interaction between constructors and exceptions. Warnock applies.
<http://xrl.us/jwts>
Continuation Return Values
Bob Rogers provided a patch allowing Continuations to return values. Leo
applied the patch.
<http://xrl.us/jwtt>
Dynamic PMC Link Dependency
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.
<http://xrl.us/jwtu>
Restricted clear_eh
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.
<http://xrl.us/jwtv>
"*_config.o" Issues
Florian 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).
<http://xrl.us/jwtw>
bc Needs Python
Jerry Gay noticed that languages/bc would fail most of its tests without
python. It should probably probe for that.
<http://xrl.us/jwtx>
GraphViz of Parrot
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.
<http://xrl.us/jwty>
Tcl Globals Failure
Will Coleda noticed that r11431 is suddenly failing a few Tcl tests.
<http://xrl.us/jwtz>
Param Count Checks
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.
<http://xrl.us/jwt2>
Method Look up in Dynamic PMCs
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.
<http://xrl.us/jwt3>
Perl 6 Language
"as if"
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.
<http://xrl.us/jwt4>
ff operator
Larry renamed the flip flop operator to " ff ". People rejoiced loudly.
<http://xrl.us/jwt5>
New T-Shirt
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...
<http://xrl.us/jwt6>
Protype Based MMD
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.)
<http://xrl.us/jwt7>
S06 Questions
Dakkar had a few questions about S06. Larry had a few answers.
<http://xrl.us/jwt8>
Named Unicode Characters
larry announced that one could put named Unicode code points into
strings like this "\c[LATIN CAPITAL LETTER A, COMBINING RING ABOVE]".
<http://xrl.us/jwt9>
Perl 6 can "goto hell;"
Larry announced the addition of a "goto" statement.
<http://xrl.us/jwua>
Something Between State and My
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.
<http://xrl.us/jwub>
Universal Roles
Yuval Kogman wants a really powerful sort of automatic application of
roles, I think. Warnock applies.
<http://xrl.us/jwuc>
Macros
Herbert Snorrason wants more specifics on macros in Perl 6. Larry gave
him some.
<http://xrl.us/jwud>
Synopsis Typos
Yiyi Hu and Andrew Savige found a few typos in a few synopses. Larry
graciously fixed them.
<http://xrl.us/jwue>
Automatic Instantiation
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.
<http://xrl.us/jwuf>
Perl 6 Development Process
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.
