cschwenz From yesterday: 19:28 raydiak looks like spec changes..."source-url" was the old place to declare it, now specs say it goes in "source" in a "support" subobject...but Cairo's meta has "source-url" inside "support", so not valid either the old or new way I guess 05:54
where is the referenced spec?
skids probably design.perl6.org/S22.html 06:01
cschwenz thanks :-) 06:04
doc.perl6.org/language/modules is in conflict with design.perl6.org/S22.html#DISTRIBUTION . who (or what process) updates doc.perl6.org/ ? 06:10
skids doc is in github pel6/doc repo. I don;t know if the update scripts are in there as well. Changes to the repo auto-update within 10 minutes or so. 06:11
cschwenz thanks! :-) 06:12
skids However, there is a dichotomy between modules.perl6.org and S22.
cschwenz ???
can you explain the dichotomy?
skids S22 is intended for CPAN, IIRC, and modules.perl6.org is "the ecosystem" which predates that. 06:13
isBEKaml I think he means thatThere are no start and end dates. You can join at any time and start learning. You can pick a learning path of your choosing and learn at your own pace. modules.perl6.org do not always keep up with spec changes in S22
grr
isBEKaml really should fix the touch pad
skids (predates not CPAN itself but S22)
cschwenz does panda track S22?
isBEKaml I think he means that modules.perl6.org do not always keep up with spec changes in S22
skids I seem to recall panda getting a few updates for S22 but likely not all the way, yet. 06:15
cschwenz hmm
skids There's a lot of work needed in this area. 06:16
cschwenz so, when creating a module for deployment… there are three moving targets to take into consideration? (S22, de facto, and panda)
skids Well, the latter two are mostly the same. 06:19
For now you'll want a META.info in the current ecosystem format and then a META6.json in the S22 format.
cschwenz is there a versioned copy of S22?
skids Not sure they are stamping versions on the desgn docs quite yet. 06:20
cschwenz :-(
skids If you look at Sum (one of my modules) it has both files, if you need examples.
cschwenz okay, will do 06:21
skids The design docs are github perl6/specs.

FROGGS :/ 07:13
nwc10 were the busses busses yesterday too? (or trains?) 07:14
lizmat they were busses all the time, I understand
although FROGGS only lives 1km outside of Berlin, it's still an hour's ride from his place to the Betahaus 07:15
(Berlin is not small)
FROGGS would take more time on sunday, but I dont know how much 07:16
nwc10 I thought that only London was London. If you see what I mean. 07:17
I didn't realise that Berlin was just as epic 07:18
cschwenz <soapbox> if we want truly liveable mega-cities, then we will need a shift in thinking about how we construct cities. (current modes of building cities max out around 1 million people) </soapbox> 07:20
FROGGS if there were no railworks it would take about 30 minutes to the center on business days, and about 45 to the betahaus

nwc10 aha, so I was sort of guessing right about rail works? 07:25
FROGGS probably... I did not get the reference about london :o) 07:26

labster Is str $!value in class Str equivalent to the result of nqp::unbox_s()? 08:11
lizmat yeah, was just looking at that, but yeas 08:12
*yes
according to BOOTSTRAP.nqp anyway
labster Because I think there are a lot of methods in Cool.pm that can be made faster by removing the unboxing op in Str.pm. 08:13
lizmat Str.HOW.add_attribute(Str, BOOTSTRAPATTR.new(:name<$!value>, :type(str), :box_target(1), :package(Str)));
labster Yeah, I saw that line, just didn't know how to interpret it :) 08:14
08:14 cschwenz left, cschwenz1 left
lizmat has str $!value is box_target # in Perl 6 code 08:14
08:15 anaeem1__ left
labster Yeah, it's the "is box_target" part I'm less clear on. I don't really know NQP, but I think I'm learning. 08:15
08:16 araujo joined, anaeem1_ joined
lizmat afaik, box_target is what is used to encapsulate self 08:16
so nqp::unbox_s(self) is the same as $!value
(someone please correct me if I'm wrong) 08:17
FROGGS: making CURLI even more lazy by doing the from_json (or whatever we're using) inside candidates() once? 08:18
instead of in BUILD ?
labster Well, for now, the opinion of lizmat++ is good enough for me. I'm going to try moving some methods from Cool.pm to Str.pm and see if I can find some speed improvements. 08:22

FROGGS lizmat: true 08:35
lizmat FROGGS: especially if you're developing a module, it will most likely live in a CURLF anyway
08:35 cschwenz_ is now known as cschwenz
lizmat and not get to the CURLI 08:35
FROGGS yes, on the other hand you probably load the modules from the biggest CURLI 08:36
(non-dev stuff)
08:36 cschwenz is now known as cschwenz_
lizmat will, I think the extra check would be dwarved by the CPU used for the search 08:36
so the gain of not having to do it when *not* needed, could be significant in many use situations 08:37
one could even go so far as to create a separate CURLI for e.g. the whole of CPAN / ecosystem

nwc10 FROGGS: I think that that commit is reasonable. I'm a bit surprised that the waitpid() call is blocking (I thought we were deep down trying to be a non-blocking event loop) 09:25

FROGGS we have to block for a spawned process to get its exit status... and I dont know other way to do that 09:28
lizmat I assume "use nqp" should have the same scope semantics as "use fatal", right ?
FROGGS probably, yes 09:29
lizmat as in: only allow in the scope that has nqp:: calls, but not in inner scopes ?
FROGGS only lexical inner scopes, but not scopes you call into 09:30
so this should be valid I think: use nqp; sub foo { nqp::whatever(); for ^2 { nqp::alsothat() } } 09:31
so 'use nqp' needs to set a lexical/local variable, and we need to check for that when calling nqp ops somehow 09:34
tadzik hmm, in Perl 6 grammars, where do you put :Perl5/:P5 to make it work?
FROGGS but I think it is easy to get wrong / unperformant
m: grammar G { rule TOP { :P5 \N{EURO SIGN} } }; say G.parse('€') 09:36

nbdsp Greetings! Could someone advise please how to correctly update Rakudo from Git? When I do 'git pull', 'make', 'make install' I get then an error "Missing or wrong version of dependency 'src/gen/m-CORE.setting' " when using some module or when installing some module with "panda install ...". Clean new install of Rakudo solves the problem, but how to correctly update from git? 11:36
RabidGravy make distclean? at a guess
masak nbdsp: after 'git pull', you'll want something like 'perl Configure.pl --gen-moar --gen-nqp --backends=moar'
lizmat git pull/make/make install usually works for me
masak nbdsp: that should fix it.
lizmat also, if you have strange errors: rm -rf install 11:37
masak nbdsp: very occasionally, it doesn't. than I... what lizmat said.

tl;dr: a "token {}" object can only be passed once, otherwise it gets broken in transport 14:17
lizmat jnthn: after consultation with masak and FROGGS_, I just went for it
jnthn lizmat: We're not putting in anything magical like a "bootstrap-from-nqp", if nothing else we are going to just check that --setting=NULL was passed and assume we should call the approprite things on $*W to do it. 14:18
No point adding special syntax when we can just wedge it in somewhere around -M handling.
So that makes it simpler, even.
lizmat so no setting should assume loading Perl6::BOOTSTRAP ? 14:19
I can do that :-)
jnthn lizmat: Note tha it's not "no setting" which defaults to CORE, but rather an explicit --setting=NULL 14:20
lizmat: But we hang more things off that peg already.
lizmat found it
jnthn lizmat: See the line "unless %*COMPILING<%?OPTIONS><setting> eq 'NULL' {" for example :) 14:21
ok :)
lizmat yeah that one :-)
jnthn Except that's an unless and you're doin an if :) 14:22
Note that use is still going to have to go through $*W
Since it needs to do some code-gen
But it can from there call Perl 6 code.

hi timotimo
timotimo turns out i locally overrided $res_kind so i ended up with NQPMu (probably) in the $res_kind at the end of compile_var, which the rest of the compiler interpreted to mean "generate a new register that's nulled and use that henceforth"
DrForr Aha, thanks.
timotimo jnthn: i'm not exactly sure what a variable that's decl'd to be a localref would ... do ... ? 15:25
except if it's a parameter; in that case it can make sense to me
15:28 laouji left 15:29 cschwenz left
timotimo i suppose i should build the same tests for lexicalref/lexical that i've built for localref/local 15:30
jnthn timotimo: Same as if it's decl'd as a lexicalref
timotimo: It's an obj type register and you may bind to it
lizmat jnthn others: how would I do: @*NQP_VIOLATIONS[$line].push($op)
in nqp (Grammar) ?
timotimo jnthn: OK, so i'd op<bind> something that'd decl'd local but referenced in localref scope into the localref'd thing? 15:31
jnthn timotimo: If you access it as a localref you get the thing in the register
timotimo: If you access it as a local then you get it decont'd. 15:32
timotimo and if i access it as a local, i get the value
jnthn decont_[ins]
*nod*
timotimo OK, that makes a lot of sense
jnthn lexical and lexicalref behave the same way
timotimo good, i think i can make tests for that
jnthn We need them to be very close semantically since we lower lexicals to locals.

instead, design your grammar so that either operand is an expression with a higher precedence than postfix if expressions 17:36

I would recommend against it as the tests that *really* matter, are TODO's because we cannot actually send signals yet 23:03

japhb Is Proc::Async now running correctly on r-j? 23:36
Or still just r-m?
lizmat japhb: I have no idea 23:38
japhb Fair enough. :-) 23:40
How was the hackathon? (I know it occurred, but I have no idea what awesomeness transpired ....) 23:41
dalek kudo/nom: 4ba4aab | lizmat++ | src/Perl6/Grammar.nqp:
Handle all pragmas with -M (not just "strict")
 23:43
lizmat well, if you look at the past 4 days git log
I would think a lot has happened on the P6 end :-) 23:44
there was a lot of discussion at the QA hackathon
mostly about P5 / CPAN
I'm pretty sure we will here more about that in the near future from the people involved 23:45
also: PAUSE has been migrated from Apache/mod_perl to Plack
and 5.24 (next year) will most likely allow you to transparently execute Perl 6 code if Inline::Perl6 is installed 23:46
5.22 is already in code freeze, so we were too late for that

timotimo lizmat: oooh you improved autogenerated accessors? 23:52
lizmat One of the most exciting things I saw was tadzik developing a BNF to Perl 6 grammars converter
timotimo how?
:D
23:52 espadrine left
lizmat they have D: on them, and they don't show up in backtraces 23:52
m: class A { has $.a }; A.a 23:53

timotimo ah
the next step for autogenerated accessors will be to actually generate code for them rather than just having closures that close over the attribute name 23:54
that ought to make accesses a bit cheaper
23:54 leont left
timotimo but custom code will be bigger in ram than just a closure clone :\ 23:54
lizmat I guess we could do that for autogenerated accessors in the core settings 23:55
or have a pragma like "use more memorry"
that would autogenerate them in a different way ? 23:56
so with 5.24 you should be able to say: "perl -Mv6 -e '.say for ^10' 23:58
iff Inline::Perl6 is installed
lizmat is tired and goes to sleep& 23:59
