Perl 6 Compiler
synopses <http://xrl.us/pb64>
Sean Sieger asked if synopses were publically available. Jonathan Scott
Duff and Will Coleda responded with information on read-only access to the
archives.
first barest-bones Relation implementation committed <http://xrl.us/pb65>
Darren Duncan announced that he has begun to implement a Perl 6 Relations
class, and described some of the features of the class.
[svn:parrot] r12294 - trunk/languages/perl6/lib <http://xrl.us/pb66>
Nick Clark commented on this revision, which was not the final form of the
patch. He also had a question on POD and whitespace, which Patrick R.
Michaud answered.
Infix macro := reparsing the LHS? <http://xrl.us/pb67>
Audrey Tang asked for details on the infix macro where she felt that
specifications did not clear up how it would be used in practice. Larry
Wall obliged with a clarification, and, following a conversation on IRC,
posted more information.
Pugs build error OS X <http://xrl.us/pb68>
Will Coleda reported a problem with building r10048. Darren Duncan
suggested trying r10054, which did not have the same problem for him.
error building pugs: "Could not find module `Data.ByteString'"
<http://xrl.us/pb69>
Dave Whipp reported a problem with installing pugs r10142, but then updated
to r10166, which solved the issue..
Perl 6 Language
'temp $x;' with no assignment <http://xrl.us/pb7a>
Yuval Kogman offered his opinion on how temp should react with an earlier
my declaration in an outside scope. Several people responded.
[svn:perl6-synopsis] r8504 - doc/trunk/design/syn <http://xrl.us/pb7b>
Audrey Tang submitted a patch relating to the S06 document. Nick Clark
asked why unint autoboxes when int does not. Amos Robinson suggested an
alternate interpretation of the text, which turned out to be correct.
replacement of $ <http://xrl.us/pb7c>
In early April, "Larry" suggested replacing $ with the Euro symbol. Darren
Duncan pointed out that $ is used in several countries, and not just in the
US and proposed using the gold standard of 'Au' to prefix variable names.
The thread continued with further April Fool's day silliness, ending with
Yuval Kogman noting that if Larry had participated in the keysigning party
at OSDC this joke wouldn't have been possible.
[svn:perl6-synopsis] r8532 - doc/trunk/design/syn <http://xrl.us/pb7d>
Audrey Tang submitted a patch to fix capitalization. Uri Guttman picked an
even smaller nit, and then they discussed having a docathon at
YAPC::NA::Chicago.
curly-quotes <http://xrl.us/pb7e>
Jonathan Lang wrote to propose having ` quotes in both single and double
variations to be used with ' and ", which would allow them to match the way
parentheses and brackets do. Larry Wall pointed out some of the
difficulties in using characters outside of Latin-1 Unicode.
Context and coercion <http://xrl.us/pb7f>
Joshua Choi asked what the conceptual difference is between context and
type coercion. According to Larry Wall, there's no difference. Larry then
helped defined coercion.
Do junctions support determining interesections of lists <http://xrl.us/pb7g>
Joshua Gatcomb wrote to the list with additional questions on junctions,
following up from his post of the previous year. Larry Wall answered that
Sets have replaced Junctions for the use described.
Set Theory (Was: Do junctions support determining interesections of lists)
<http://xrl.us/pb7h>
Jonathan Lang asked if Perl6 Sets will include set negation or a universal
set. Larry Wall noted that some existing functions sort of consider this
question, although not for Sets defined by rule. Discussion continued, with
others joining in.
[svn:perl6-synopsis] r8569 - doc/trunk/design/syn <http://xrl.us/pb7i>
Following another patch post, Rutger Vos asked if the purpose of the list
was to receive subversion logging messages. Jonathan Scott Duff added his
opinion that patches were a part of the language design.
[svn:perl6-synopsis] r8573 - doc/trunk/design/syn <http://xrl.us/pb7j>
Revision r8573 introduced some changes that TSa questioned and Juerd
disliked. Damian Conway explained the reason the changes were needed, and
several people offered alternatives.
$a.foo() moved? <http://xrl.us/pb7k>
Matt Fowles noted that there had been a change and asked when it happened,
noting that he preferred the previous style. Larry Wall replied that it had
changed at the last hackathon but was still being debated. Some of the
debate spilled in to the thread.
On signatured code attributes of a class <http://xrl.us/pb7m>
Joshua Choi asked if it was possible to use a particular syntax, and noted
that #perl6 is quite active. He requested that someone summarize the
channel.
[svn:perl6-synopsis] r8609 - doc/trunk/design/syn <http://xrl.us/pb7n>
Larry Wall submitted a patch and then commented on the patch. Nick Clark
had a question on the long dot form and Larry Wall and Ruud H.G. van Tol
offered perspectives.
Another dotty idea <http://xrl.us/pb7o>
Larry Wall returned to the subject of the long dot, which he felt was too
specific. He made a new proposal involving the delayed postfix problem.
There was a long discussion on this suggestion.
slurp, quine and context sensitivity <http://xrl.us/pb7p>
Dan Kogai requested a version of C<slurp()> which would unconditionally
return a scalar, and proposed C<swallow()>. Damian Conway offered some
suggestions within the current framework.
The "whatever" context <http://xrl.us/pb7q>
Yuval Kogman proposed 'whatever' to return the natural context of an
operation regardless of the actual context. Larry Wall noted that the
example, which involved grep, already had this functionality, and Yuval
asked if this was also true for other functions.
int context ? <http://xrl.us/pb7r>
Herbert Breunung wrote that in the Perl 6 book there was 'Integer context'
and 'Numeric context' but that he had not noted 'Integer context' in the
synopses. He wondered if the concept had been discarded. Larry Wall
clarified that it still exists.
foo..bar or long dot and the range operator <http://xrl.us/pb7s>
TSa was unclear on what the numerous long dot discussions had accomplished
and asked about a few cases. Larry Wall attempted to clarify, and TSa had
some further questions. chromatic was also uncertain of the purpose of the
long dot, and Daniel Hulme saw his point. Damian Conway tried to further
define the problem.
placeholder vs. lexical variables <http://xrl.us/pb7t>
Dan Kogai ran in to a failure with Pugs while trying something defined in
s06. Audrey Tang noted that the compiler list would have been more
appropriate, but that r9913 fixed the issue.
Capture Object: why no verb? <http://xrl.us/pb7u>
Dave Whipp felt that it was an omission that capture objects do not
consider the verb. Audrey Tang responded with an ans
[svn:perl6-synopsis] r8883 - doc/trunk/design/syn <http://xrl.us/pb7v>
A submitted patch sparked a discussion on the verb 'parse' on #perl6, which
Audrey Tang summarized. 'token:w' was seen as a better form of removing the
ambiguity. Others also posted comments on the synopsis.
[svn:perl6-synopsis] r8899 - doc/trunk/design/syn <http://xrl.us/pb7w>
Uri Guttman replied to a patch by saying that he was confused by many of
the recent changes. He requested additional examples. A few people also
addressed the documentation changes in that patch.
=$fh vs *$fh <http://xrl.us/pb7x>
Audrey Tang merged some ideas after seeing similarities between them, and
wondered if it could be seen as a general case for = to return the next
thing. Larry Wall expressed some concerns, to which Audrey responded.
svn links for the Architecture section on the website? <http://xrl.us/pb7y>
Elyse M. Grasso suggested that the synopses could link to the svn site
because the versions are lagging on dev.perl.org. Robert Spier responded
that he had modified the dev site for more regular updates.
S05: Interpolated hashes? <http://xrl.us/pb7z>
Markus Laire asked for an example of how two sections of s05 relate to one
another. A couple of people attempted to answer the question.
Adverbs <http://xrl.us/pb72>
Jonathan Lang asked how adverbs were defined and accessed within a
subroutine. Larry Wall and Damian Conway answered.
S5 - Question about repetition qualifier <http://xrl.us/pb73>
Joe Gottman noted that the repetition qualifier described in s05 seems
restrictive. Several people responded on whether the additional suggestions
would be used.
Perl 6 built-in types <http://xrl.us/pb74>
Darren Duncan had a few comments after reading s06. He discussed this with
Larry Wall, and others added their two cents.
values of undef and JavaScript <http://xrl.us/pb75>
Stéphane Payrard wondered about the nature of 'undef' as a value vs.
'undef' as the uninitialized variable state, especially in the context of
interoperability with JavaScript.
S02 - s/environmental variables/environment variables/g please
<http://xrl.us/pb76>
Randal Schwartz issued a plea for consistent use of 'environment variables'
over 'environmental variables'. There was a brief discussion on whether
these described two different concepts.
german perl6 tutorial <http://xrl.us/pb77>
Herbert Breunung announced that he is at work on a German-language version
of the Perl6 tutorial and requested help from anyone fluent in German.
Parot Porters (formerly perl6-internals)
The parrot-porters list was called perl6-internals during the period
covered by this summary.
Value PMCs in Parrot? <http://xrl.us/pb78>
Audrey Tang is in the process of porting Pugs's native PIL VM to Parrot,
which gave her the idea of translating the concept of 'value objects' to
Parrot. Joshua Isom, Leopold Toetsch and Chip Salzenberg responded to the
suggestion.
MSWin32 (Visual C++ 8.0) Test Results (r12017) <http://xrl.us/pb79>
Ron Blaschke reported failing tests in r12017. chromatic replied that it
was fixed in r16032.
[perl #38823] [BUG] solaris 10 w gcc <http://xrl.us/pb8a>
Leopold Toetsch noted a bug ([perl #38823] <http://xrl.us/pb8b>) caused by
the configuration system ignoring commandline options.
[PATCH] My first patch, for builtins.* <http://xrl.us/pb8c>
Andy Lester supplied a patch and said he hopes to do the same sort of
source code cleanup in Parrot that he's been doing in Perl 5. It was
applied as r12096. There was a brief discussion on how to coordinate
cleanup.
[perl #38840] Use File::Spec instead of /dev/null <http://xrl.us/pb8d>
In [perl #38840] <http://xrl.us/pb8e>, Will Coleda noted that direct
references to `/dev/null/` should be updated to use File::Spec.
[perl #38841] [TODO] Split exec run core into two distinct run cores
<http://xrl.us/pb8f>
Bernhard Schmalhofer created ticket [perl #38841] <http://xrl.us/pb8g> to
address some improvements for JIT.
[perl #38844] [TODO] Make lint, splint and tags targets <http://xrl.us/pb8h>
Andy Lester requested a few changes, such as renaming the lint target to
splint.
[perl #38849] Move internal header files out of 'include/parrot'
<http://xrl.us/pb8i>
In [perl #38849] <http://xrl.us/pb8j>, Bernhard Schmalhofer proposed that
some header files which are only included by C source files be moved to
another location.
[perl #38850] [BUG] Getopt/Obj.pir dies on non-existent options
<http://xrl.us/pb8m>
Allison Randal reported bug [perl #38850] <http://xrl.us/pb8n>, which Bob
Rogers felt could be attributed to r11444. The problem involves how
`get_options` reacts to a non-existent option.
early draft of exceptions PDD <http://xrl.us/pb8o>
Allison Randal posted an early draft for exceptions and requested feedback.
Bob Rogers posted a contribution to the document. This led to a discussion
on HLL exception handlers.
[perl #32642] [TODO] Remove Perl* PMCs from parrot's basic PMCs, src and
languages <http://xrl.us/pb8p>
In [perl #32642] <http://xrl.us/pb8q>, Bernhard Schmalhofer noted that
Perl* PMCs are no longer used in the Parrot core. He asked if it was
possible to rename or move the PMCs. Several people agreed, but it was
pointed out by Patrick R. Michaud that Chip Salzenberg did not want Parrot
to change significantly until 1.0.
Re: [perl #32507] [TODO] ResizableIntegerArray missing vtables (e.g., pop)
<http://xrl.us/pb8r>
In April, [perl #32507] <http://xrl.us/pb8s>, which turned out to not be
related to PGE, was marked as resolved.
installing svn parrot <http://xrl.us/pb8t>
Sean Sieger asked if there was a problem with Parrot, and Nick Glencross
offered an installation suggestion.
Re: [svn:parrot] r12129 - trunk/src <http://xrl.us/pb8u>
Nicholas Clark was afraid r12129 was masking the real bug, but Leopold
Toetsch explained the reasons behind the patch.
t/examples/streams.t issue on Windows <http://xrl.us/pb8v>
Ron Blaschke reported a failing test on Windows and suggested changing
`svn:eol-style` to "LE" or to have tests normalize CRLF to LF.
[perl #38888] PGE::P5Regexp failures. <http://xrl.us/pb8w>
In ticket [perl #38888] <http://xrl.us/pb8x>, Will Coleda noted that the
Tcl test suite has failures. There was some discussion on the location of
the problem, and a patch was created and applied as r12181.
[perl #38896] [TODO] Integer PMC missing math methods. <http://xrl.us/pb8y>
Will Coleda reported in [perl #38896] <http://xrl.us/pb8z> that there are
many math ops that work on Float PMCs but not Integer PMCs. Nicholas Clark
and Patrick R. Michaud expressed some concern over the behavior. More
discussion followed.
[perl #38897] [TODO] fail during makefile generation if line ends in '/'
<http://xrl.us/pb82>
Jerry Gay made a request in ticket [perl #38897] <http://xrl.us/pb83> for
slash replacement during makefile creation.
[perl #38903] Tcl - namespace borkage <http://xrl.us/pb84>
In [perl #38903] <http://xrl.us/pb85>, Will Coleda reported that Tcl's use
of globals in the `_Tcl` namespace was causing issues.
Parrot_init shouldn't be described in doc/embed.pod <http://xrl.us/pb86>
Pawel Murias submitted a patch which removes Parrot_init. It was applied as
r12200.
[perl #38907] namespace-related bus error <http://xrl.us/pb87>
Will Coleda reported a Parrot bus error in ticket [perl #38907]
<http://xrl.us/pb88>, which was resolved with r12201.
[perl #38914] perl Configure.pl fails on Mac OS X 10.4.6 on Intel iMac
<http://xrl.us/pb89>
Gregor N . Purdy created a ticket ([perl #38914] <http://xrl.us/pb9a>)
which turned out to be a false alarm.
@slash@ in Makefile.in Files <http://xrl.us/pb9b>
chromatic noted that a patch replaced `@slash@` with `/` in the Makefile
and wondered if the former was still required or even desired. Both Jerry
Gay and Will Coleda recommended using `/`.
[perl #38929] [TODO] Get executable code out of .h files <http://xrl.us/pb9c>
Andy Lester proposed, in ticket [perl #38929] <http://xrl.us/pb9d>, that
functions in `include/parrot/jit_emit.h` be removed and up in a .c file.
Re: [perl #38931] [RFE] Double-quoted strings automatically determine string
type <http://xrl.us/pb9e>
In [perl #38931] <http://xrl.us/pb9f>, Patrick R. Michaud noted that
double-quoted strings are assumed to be ASCII unless prefixed by a charset
identifier such as 'unicode:'. He felt it would be useful if PIR emitters
in Parrot automatically used \u or \x in double-quotes to generate an
identifier. Nick Clark said that he felt the reason for the ASCII
assumption was to avoid the ambiguity that comes from assuming the
identifier. There was further discussion, and in the end Patrick withdrew
his request.
Namespaces TODO list, April 16 '06 <http://xrl.us/pb9g>
Chip Salzenberg posted a list of things to do to bring Parrot in line with
the namespace revisions in pdd21. chromatic asked for clarification, which
was provided.
namespace bug 2? <http://xrl.us/pb9i>
Will Coleda reported a possible namespace bug. Leopold posted a workaround,
and Chip Salzenberg fixed it in r12310.
tcl lexical failures, PDD20, PDD21 <http://xrl.us/pb9j>
Will Coleda had some thoughts on why Tcl was having failures, and answered
his own post due to an off-list contribution from Matt.
[perl #38957] hash test failures <http://xrl.us/pb9k>
In [perl #38957] <http://xrl.us/pb9m>, Will Coleda reported a persistent
failure. There were other reports of failures, and some of successes.
[perl #38958] hash/iterator failures <http://xrl.us/pb9n>
In [perl #38958] <http://xrl.us/pb9o>, Will Coleda reported some
long-running bugs. Matt Diephouse reported that he did not see the problem.
RFC: Possible SoC Proposal <http://xrl.us/pb9p>
Alberto Simões reported that there was a proposal to create a compiler for
LISS. chromatic thought it sounded like a good idea, and Ruben Fonseca
expressed interest. The discussion continued in
<http://xrl.us/pcam>.
What version of perl is required? <http://xrl.us/pb9q>
Andy Dougherty reported a mismatch between documentation and configuration
as to which version of Perl 5 was required. This was resolved.
[perl #38960] [BUG] test troubles <http://xrl.us/pb9r>
In In [perl #38958] <http://xrl.us/pb9s>, Leopold Toetsch reported some
failures. Some additional questions were asked, and Megavlad expressed
interest in Parrot bytecode.
Working on languages/python <http://xrl.us/pb9t>
Tyler Coumbes posted to inform that he is working on getting the Python
PMCs to compile with the current Parrot release (0.4.3).
[perl #38964] .sub names can't be Unicode. <http://xrl.us/pb9u>
In [perl #38964] <http://xrl.us/pb9v>, Will Coleda reported a bug. It was
addressed with r12863.
[perl #38969] parrot source does not conform to standards
<http://xrl.us/pb9w>
In [perl #38969] <http://xrl.us/pb9x>, Jerry Gay reported that there are
many exceptions when running `per tools/dev/check_source_standards.pl`.
[perl #38975] [PATCH] Update PLATFORMS <http://xrl.us/pb9y>
Several failing tests were reported in [perl #38975] <http://xrl.us/pb9z>.
Andy Dougherty offered a patch, which was applied as r12427.
[perl #38976] ResizablePMCArray uses too much memory <http://xrl.us/pb92>
Andy Dougherty created ticket [perl #38976] <http://xrl.us/pb93> to report
a massive increase in memory requirements.
[perl #38978] [PATCH] Fix unitialized register error in t/pmc/file.t
<http://xrl.us/pb94>

<http://xrl.us/pb96>
Andy Dougherty supplied a patch with [perl #38979] <http://xrl.us/pb97>,
which was applied as r12424.
[perl #38982] [TODO] refactor long test files <http://xrl.us/pb98>
Jerry Gay proposed that some test files be refactored, as they were too
long. This was in ticket [perl #38982] <http://xrl.us/pb99>.
is_deeply() is painful <http://xrl.us/pcaa>
chromatic asked for some suggestions on handling nested data structures for
his work on `is_deeply()` in Test::More in PIR. Leopold Toetsch and Audrey
Tang offered suggestions.

large set of updates to PGE.
MSWin32 (Visual C++ 8.0) Test Results (r12442) <http://xrl.us/pcac>
Ron Blaschke reported a series of failing tests, some of which were already
reported. Others were fixed, and others were known TODO items.
[perl #39013] [PATCH] Two more uninitialized registers <http://xrl.us/pcad>
Andy Dougherty supplied a patch in [perl #39013] <http://xrl.us/pcae>,
which was applied as r12503.
[perl #39018] t/pmc/complex failures on Solaris 8/SPARC <http://xrl.us/pcaf>
Andy Dougherty created [perl #39018] <http://xrl.us/pcag> to document some
non-urgent failures.
Hundreds of errors? <http://xrl.us/pcah>
Andy Dougherty reported many failing tests, and Patrick R. Michaud asked
for clarification.
