Guest54457 yes, he'll have to answer 00:04
FROGGS woolfy / timotimo: I guess that "this week" refers to the week when the APW happened 00:09
gnight 00:10
timotimo oh, hm 00:10
did we have any good weeks since? :P
TimToady what the heck is t/spec/S02-magicals/78258.t? 00:36
TimToady nevermind, was looking in the wrong subdir for UsedEnv 00:37
though I'd still like to understand the number 00:38
Mouq TimToady: rt.perl.org/Public/Bug/Display.html?id=78258 ? 00:41
timotimo there's an artist who has a track called "43644466" which i really like a lot. but i couldn't figure what it means, so ... perhaps 78258 is like that? 00:42
timotimo kind of interesting thing on the side: the for_push benchmark (i believe) is spending 9.25% of its time in Array::of and 2.82% of its time in Perl6::Metamodel::ContainerDescriptor::of, which i guess is what the of method of Array is calling immediately 00:48
this is when the for loop has 1024_000 iterations
and that's exactly how often both ofs are being called 00:49
m: say 191.68 / 1024_000
camelia rakudo-moar ac27d2: OUTPUT«0.00018719␤»
timotimo that's not really terribly much time per call 00:50
m: say "each call to push takes 857.39 / 1024_000 miliseconds"
camelia rakudo-moar ac27d2: OUTPUT«each call to push takes 857.39 / 1024_000 miliseconds␤»
timotimo m: say "each call to push takes { 857.39 / 1024_000 } miliseconds"
camelia rakudo-moar ac27d2: OUTPUT«each call to push takes 0.0008372949 miliseconds␤»
timotimo (that's exclusive time) 00:51
timotimo m: say "rc-dragon-curve takes { 1620.63 / 8149 } miliseconds to call print each time something goes out to the screen" 00:56
camelia rakudo-moar ac27d2: OUTPUT«rc-dragon-curve takes 0.1988747 miliseconds to call print each time something goes out to the screen␤»
timotimo m: say "adding a my $*OUT to the very beginning of rc-dragon-curve takes that number down to { 1567.58 / 8149 } ms per call." 00:59
camelia rakudo-moar ac27d2: OUTPUT«adding a my <STDOUT> to the very beginning of rc-dragon-curve takes that number down to 0.1923647 ms per call.␤»
timotimo hah, oops :D
timotimo well, doesn't seem *that* worth it 01:02
timotimo um ... wat 01:05
% time seconds usecs/call calls errors syscall
93.64 0.032699 0 126649 118380 write
where does that ridiculous number of errors come from?

raydiak is it common for the profiler to go into an endless loop on code that otherwise runs normally? the script produced its final output after 30-60 seconds, but has been running for like 10 minutes since then 01:33
timotimo oh yeah
the profiler takes a bit of time to output its dump 01:34
especially since it records a complete call stack ... all the way down
raydiak ah, okay I'll be patient 01:35
timotimo if you're interested in making that better, i've started work on code to summarize the call graph after a certain depth has been reached
but it produces bogus results :(
if you want to look at that code, i'd much appreciate it
github.com/MoarVM/MoarVM/commits/f...raph_depth - find the code here 01:36
raydiak oh yay the profiler returned, I can use my web browser again :) lemme see if it looks like something I'd have a clue about 01:37
timotimo hahaha
check the size of the html file
raydiak heh 58 megs 01:38
timotimo ouch %)
your browser will likely be eaten by an oom
raydiak it's how I write the transformation routines in math::symbolic...basically a "1 while s/.../.../", except in my own super-slow tree-node-pattern-matching subs 01:39
or, I'm assuming...we'll see if chrome opens it 01:40
ew C 01:41
timotimo it'll open it just fine, but it won't show any data
then it'll say "it's dead, jim"
raydiak last time I gave it enough time, it actually loaded for a simpel Pray run 01:42
timotimo impressive :) 01:43
ssqq__ :camelia :m say 'helo'
raydiak for a $180 USD pawn shop laptop, yes it is :)
hooray it did load...
raydiak this whole part of things is one of the top things on my non-Math::Symbolic p6 list...wanna get to all those interface improvements you suggested, timotimo++ 01:44
Mouq m: say 'helo'
camelia rakudo-moar ac27d2: OUTPUT«helo␤»
raydiak sees a 60-million-character string of JSON being parsed, and no longer wonders what is so slow about the profiler 01:52
colomon is that the profiler input or output 01:53
?
raydiak output
ran it on a math::symbolic run, gave me 58 megs, all of it is a string being JSON.parse'd all at once :P 01:54
raydiak I mean, vim takes several seconds just to seek to the beginning or end of this line :) 01:55
timotimo yeah, browsers are not terribly fond of such big json documents, i fear 02:05
raydiak: what interface suggestions do you mean? for the profiler?
raydiak: tomorrow (or maybe if i can't fall asleep again tonight) i'm going to add a distinction in the allocations: allocated from a spesh'd frame, allocated from a jitted frame or allocated from an unoptimized frame 02:06
raydiak considering json is valid javascript, I question the wisdom of doing this this way...I'm trying to just s/JSON.parse('<stuff>')/<stuff>/ and see if it nets huge gains without breakage, but vim isn't cooperating witht he incredibly long line
timotimo: yeah for the profiler, remember you gave me a little list of possible improvements like a week or two ago? 02:07
timotimo yep i did :)
timotimo moves to a different place 02:08
jakesyl Is there a perl 6 tutorial somewhere 02:09
timotimo jakesyl: vendethiel recently gave this presentation: slides.com/namidoc/learn#/ 02:10
well, a lightning talk really
it has some good pointers
raydiak several resources listed here: perl6.org/documentation/ the learn perl 6 in y minutes one is one of the most recent afaik 02:13
raydiak removing the JSON.parse did work, but didn't speed anything up noticably 02:20
need to profile the profiler :) 02:21
japhb suddenly has Men At Work running through his head 02:24
xiaomiao cc1: some warnings being treated as errors 02:28
... what joker added that to nqp makefile(s) ? :D
raydiak timotimo: sorry, I've been trying to follow and look for mistakes in your profiler branch, but my head seems to be more in a squishy creative place right now than a rigid analytical region of the mindscape :) 02:57
timotimo i think it'd probably help a whole lot to actually go ahead and profile the same short little program with decreasing levels of flattitude in that routine and compare outputs
i was too lazy to do that ...
anyway, way past bedtime 02:58

timotimo o/- ← "dropping the mic" emoticon?
raydiak epic :)
raydiak this might be (only a little?) premature, but do we have anything like a p6 style guide/best practices/something like that? 03:02
timotimo maybe o/_ would work better?
actually we do; they are called "well-thought-out practices"
github.com/moritz/perl6-wtop - there is not much yet
maybe when i wake up there'll be more! :P
\o
raydiak cool, thanks \o 03:03
there are just so many choices to be made when trying to spec an api in p6 03:05
xiaomiao hrm. I can't quite figure out how nqp generates its Makefile 03:20
too many indirections :(
tony-o timotimo: submitted a pr containing management speak for the readme 03:26
raydiak wow I'm sold, I better add more scalable synergy enterprise features to my resume :) 03:38
tony-o we could use people like you to get stuff done 03:47
:p
moritz xiaomiao: it's Configure.pl uses a templating mechanism in tools/lib/NQP/Configure.pm with the templates in tools/build/Makefile-*.in 05:18
xiaomiao moritz: I can't quite figure out where the CFLAGS come from, but they are extremely optimistic
(gcc 4.9.2 doesn't appreciate them at all, so I just sed them away)
moritz xiaomiao: they are passed on from parrot's/moarvm's configure 05:20
xiaomiao ouchies. 05:21
ugexe ive been getting a thread error on moar/jvm (but not parrot) during panda's rebootstrap while installing JSON::Tiny 05:32
starting today i believe
so im guessing it has to do with a recent commit 05:34

grondilu wrong chann again, sorry guys
grondilu I need to either pay attention or find a way to have irssi highlight different channels with different colors or something. 05:58
TimToady either that, or just admit you're human like the rest of us :) 06:01
unless, of course, you're not... :) 06:02
grondilu sometimes I wonder :-)
since I'm here, how is the great list refactor going? Is it coming soon? 06:03
dalek ast: 06a85e4 | usev6++ | S03-operators/arith.t:

ugexe rerunning the tests they are now passing. using the same commit id as what failed before (same with JSON::Tiny) 06:27
TimToady grondilu: pmichaud++ said he was gonna have a chance to work on it a lot this week, looked like 06:28
grondilu ok, great 06:36
ugexe hmm restarting the travis test *yet again* it fails with the same error of Internal error: zeroed target thread ID in work pass 06:37
raydiak ugexe: you need a "print '';" somewhere :)
ugexe its during JSON::Tiny install from panda 06:38
raydiak it's the same heisenbug I kept running into and then couldn't reproduce when I had people's attention 06:39
removed all the prints from my code and the bug didn't come back due to later changes I had made, I guess
ugexe on the jvm JSON::Tiny gets installed, but then during panda install Panda::Tester gets a IllegalThreadStateException during compiling Tester.pm 06:41
was yours different on different vms?
from what i can tell panda doesnt have this problem 06:42
s/panda/parrot/
raydiak was only developing on a very recent moar
ugexe yeah moar does it too, just at an earlier stage
raydiak for me it was in my own code though
raydiak so I tried to track it down and it would go away, so I'd just leave a print in there somewhere and move on until I felt up to golfing it 06:43
ugexe gist.github.com/ugexe/d103c8eee285...-txt-L2863 06:44
hmm im good at spamming print statements
raydiak it's good that we have another example of the failure, too...but I can't reproduce it...what version is your rakudo? 06:46
ugexe its the latest 06:46
raydiak hm I'll rakudobrew and see if it breaks here, if that helps 06:47
ugexe travis-ci.org/ugexe/P6TCI/builds/42009558
i can refresh that test and it seems to fail 50% of the time
you can see the slightly different error from jvm as well, and how parrot passes
ugexe you can compare the rakudo/json::tiny/etc commit ids to the ones here where they all passed travis-ci.org/ugexe/P6TCI/builds/42044969 06:49
they are all the same
raydiak json::tiny just built successfully here, I'll try it a few more times when everything else is done 06:54
raydiak failed to fail 5 times in a row 06:59
ugexe maybe its rakudo/moar/jvm then 07:05
not sure what could be different between building the same commit though
i cant get it to happen outside the travis machines either
raydiak huh...what is this travis thing anyway? 07:06
ugexe every time you make a commit, travis gets a hook from github and it pulls in your code and runs the tests for it (according to a config file you setup) 07:07
raydiak oh neat
ugexe those links are to the output of those tests 07:08
raydiak yeah, I figured out how to read them when I noticed the lines are folded 07:09
ugexe oh yeah, i forgot about that
raydiak "panda-fetch: command not found" didn't look like my error :) 07:10
ugexe thats not the error
panda-fetch wasnt installed
because of the thread error
travis-ci.org/ugexe/P6TCI/jobs/42009559#L910 07:11
:/ that doesnt unfold the line either it looks like 07:12
raydiak yeah no I got to it eventually, was just making fun of my initial confusion 07:14
can you manually run commands in a travis vm? would be nice if we could reproduce an instance of it with something helpful like --ll-exception, or valgrind or whatnot 07:16
ugexe yeah, but rakudobrew build-panda doesnt let us pass any flags 07:17
github.com/ugexe/P6TCI/blob/master/.travis.yml
i guess not manually per se
raydiak yeah you'd have to clone json::tiny and manually run the compile command
ugexe you can manually put them all in a config and run them
raydiak that'd work 07:18
ugexe whats interesting is it fails during compile for moar but not jvm 07:21
but using it with the jvm it errors at runtime
ugexe and parrot has no threads so presumable thats why this problem hasnt popped up there yet 07:22
raydiak the error for jvm looks like when it's building panda, after it's done with json::tiny 07:25
raydiak jvm dying here: github.com/tadzik/panda/blob/maste...er.pm#L136 07:28
raydiak should you be able to assume that a pipe to a child process can be closed after 'for .lines' finishes? 07:33

raydiak ugexe: will it still work if I just delete the before_script, script, and after_success portions, and put the manual compile commands in place of panda-build under install? 07:46
TimToady other than that, and bumping the nqp version in rakudo, I think I'm finally done with longest literals 07:47
raydiak ugexe: actually, never mind 07:48
ugexe ive been retesting a build like that for the last 30 minutes with no failures 07:52
raydiak ah
ugexe github.com/ugexe/P6TCI/blob/306d60...travis.yml 07:55
thats how you can do build-panda and then a manual panda install
er you want compiled commands. yeah you can do that too
raydiak ah, for the jvm failure...yeah meant for the json::tiny moarvm failure 07:56
wonder if a --ll-exception flag for panda to pass through to builds and tests would be worthwhile 07:58

.oO( $BLOG! $BLOG! $BLOG! )
 09:39
masak ooh, and I know what to blog about. :) 09:44
Ven moar power to the $BLOG :-) 09:46
JimmyZ moar jit power ;) 10:10
masak today's discussion topic: is metadata just data with delusions of grandeur? :) 10:38
seriously, I've seen domains that had loads of metadata, but no actual data. 10:39
brrt hmmm good question
when do we call data metadata
masak I've heard people call comments in code metadata. that was Steve Yegge, IIRC. 10:40
tadzik when it's data about data, like an index
huf after you've said hello
masak tadzik: so... most data? 10:41
moritz masak: I find meta data just as scary as data 10:41
tadzik probably :)
huf never met a data i didnt like
moritz masak: "so you connected to pornhub.com? don't worry, we don't know the contents of your request"
masak my point is that it doesn't take much for data to be about data. 10:42
heck, every foreign key ever is metadata.
huf yeah, but code is data too
brrt hmmm
masak code is operating on data, so it's metadata.
huf so these terms are clearly very relative to the current topic
brrt i'm not sure i agree whether a foreign key is metadata
its part of the shape of the data
tadzik what if it's operating on code? That's so meta 10:42
brrt a pointer isn't metadata
huf "metadata" is like "higher"
it's meaningless without context :) 10:43
raydiak imo metadata is a question of perspective...if bring your context down a metalevel, data is viewed as metadata...up a level and vice-versa happens
masak huf: technically "beyond" or "beside".
huf masak: yeah, but same applies to those too
brrt hmm... 10:44
no
it may be in the interest of intelligence agencies to call urls and email topics metadata, but they're really part of the message 10:45
masak well, all I really wanted to do was sow some doubt that the notion of "metadata" has any real meaning except perhaps in a sufficiently defined domain.
huf what's the difference between a crocodile?
raydiak there wasn't already doubt? :)
huf it's longer than green.
Ven masak: I have no idea what "metadata" is supposed to mean 10:46
masak I think we all agree that it's all ones and zeroes. whether we call them "data" or "metadata".
Ven that's an implementation detail :-)
brrt i think those well-defined domains are more common than you might think
e.g. in C? struct values are data, struct type is metadata 10:47
in SQL, metadata is the schema, data are the rows
masak brrt: never heard of that distinction.
brrt well, i'd put the difference between structure and value 10:48
structure is always meta
much like the distinction between species have little to do with the individuals, but with the properties-of-all-individuals
masak brrt: seems to me you're simply talking about types/schemas vs values. not the typical definition of "metadata".
rurban metadata cannot lie, content usually does. that's the reason
brrt i'd argue that this is the typical definition of metadata, and that (if anything) this meaning has been corrupted for political purposes 10:49
Ven political metadata? what?
brrt like moritz'es example, the fact that you connected to pornhub or any other site is part of the exchange
it's data
Ven has never heard of "metadata" outside of programming contexts
brrt no, the *meaning* of the word 'metadata' was stretched for political reasons :-) 10:50
masak rurban: hah! someone should write a crime thriller based on the flawed idea of "metadata cannot lie".
rurban well, you can fool metadata also, but that's much harder
masak it's the modern equivalent of "the camera never lies"
rurban ipspoofing, mac spoofing, arp cache and so on
masak ah yes, *apart* from those ways.
Ven if you accept there's "metadata", then there has to be a tower of those. 10:51
DO YOU WANT A MULTIVERSE?
because that's how you get a multiverse...
rurban or morphing (cast, nci reinterpretation)
masak .oO( ...he shouted, panicked, in all-caps )
brrt i don't want a multiverse. i'd have no idea what would give energy to power all multiverses 10:52
on the other hand
dark energy
i suspect that, if GDR secret service had need for it, they'd make a convenient distinction between spying and 'meta-spying' too 10:54
masak if I'm charitable, I can have "metadata" mean "annotation data". as in "this data is not strictly necessary in the domain, but it's nice to have".
brrt hmmm
but that implies that there is potentially a domain on which that data is necessary 10:55
so that would fit the comment definition, as e.g. pod comments are input for another tool (perldoc)
and anyway, that definition still excludes mass-scale spying data :-) 10:56
masak yes, "there is potentially a domain" is exactly right. that is, the view on metadata is *domain-dependent*. 10:58
we could think of one or more "meta-domains" in which what's metadata here is data there. 10:59
brrt sometimes aristotle is useful :-)
Mouq e.g., file systems 11:00
brrt in a sense, for something to be 'really' metadata, it should have no meaning in the 'data' domain 11:01
masak brrt: I don't think the definition excludes spying data. I do think it excludes structs/schemas, though.
brrt hmmmmm
masak brrt: don't know about "no meaning". but it shouldn't be primary/necessary.
brrt ok, i think i can agree on that 11:02
wrt to mass surveillance 'metadata', i really do think it is weasly to call e.g. domain names 'metadata'
masak like, email subject and body are data, because that's why the email was sent. header details are metadata, and that's one reason we don't normally look at them when we read emails.
Ven
.oO( I see meta-meta-data )
brrt what about email recipient address is data
masak arguably, yes. 11:04
and I can agree about the weasliness.
Ven "metadata is the structure, like the fields. metametadata is the field structure, like (name, type). metametametadata is the data explaining what's a name and what's a type. metametametametadata is the data explaining ..." 11:08
Mouq OED: "metadata n. data that describes and gives information about other data." 11:09
masak Ven: I don't see metadata being usually about structure.
Ven: I see it more as annotating existing data, regardless of structure.
what Mouq/OED said.
Ven masak: I'm just giving an example of a tower 11:10
brrt hmmm..... i'm not sure that structure is not metadata
Mouq Data about structure is arguably metadata about the representation of the data
Ven :-) 11:11
Mouq Rather than the data per se
brrt aye
masak I don't think that's how it's normally used, though.
brrt how do you see it normally being used?
masak and it contravenes my intuition that the data would still be OK/valid/fine if the metadata weren't there.
in a sense, I see metadata as "extra", not necessary/vital for the data. 11:12
brrt hmmm....
Ven masak: it's still ok/valid/fine if the metadata isn't there ;-)
brrt fair point
Ven that's the basic idea of dynamic typing :P
masak Ven: that felt like a frivolous point at first, but I think it's actually a good one.
brrt but then, if you get down to it, structure is just a list of routines used to access values in a composite 11:13
Ven masak: it's a frivolous point
brrt so maybe it's not really metadata but metacode
masak structure is rules about data access.
Mouq ^^ that
Ven masak: "dynamic typing" should be replaced with "weak typing".
masak not necessarily code.
Ven because dynamic typing can still be based on the idea of "having a structure"
that's... still a frivolous point to me, though. 11:14
brrt difference between rules and code is a weak one
Ven we should abolish the difference :-)

camelia rakudo-moar 316f99: OUTPUT«False␤»
Ven I might be in love :)
masak I think the distinction between data and metadata (in some domains) is the kind of thing that can put up walls in the way of insight/unifications.
brrt unifications are dangereous operations :-) 11:19
Ven you misspelled "awesum" :)
brrt afk 11:29
timotimo i should have nick colors now, yay 12:54
dalek ake: 753db10 | (Arne Skjærholt)++ | src/Snake/ (2 files):

 12:59
timotimo hmm. did i mention arnsholts work on snake? 13:00
i kind of fear i didn't :o
arnsholt Mentioned in what? 13:02
timotimo my weekly post yesterday 13:03
arnsholt Aha. 'S ok =)
timotimo :S
arnsholt There's always next week =)
timotimo sometimes there's only "the week after next week" 13:05
arnsholt Or that 13:06
I'll just have to remember to do some work on snake before the next weekly summary =D
timotimo OK :) 13:07
i can live with that, if you can live with that ;)
arnsholt It's still an on-again off-again project for me, so no publicity isn't a problem 13:08
I'll just keep tinkering
rurban github down for a moment... 13:10
nope, looks like the us routing is slow 13:13
hoelzro if two compunits A.pm and B.pm each have their own package ABC {}, and B.pm defines class ABC::B {}, can code in A.pm see ABC::B even if A.pm doesn't 'use B'? 13:26
hoelzro (if, for example, main.pl uses both A and B) 13:26
sven_123 hi - what happened to planet6.perl.org? 13:29
rurban Please don't use B; this already exists in perl5 13:34
hoelzro rurban: it's just an example module name 13:35
masak rurban: even though that wasn't what it was all about in this case, what do you see as the harm of using module names that already exist in CPAN's Perl 5 namespace? 13:54
confusion?
what if it's a port of the original module?
Ugator maybe you should add to the v6 port to the perl5 module? so there is only one module? 13:58
masak I don't immediately see why that's better than keeping the modules separate.
geekosaur I don't think p5's B:: namespace is sensibly p6-able... 13:59
masak that way, both p5 and p6 users pay the size cost of both.
Ugator so CPAN will stay p5 for longterm? and p6 modules will be a completely new "world" this might cause confusion 14:01
hoelzro package ABC {} by itself is local to that compunit, right? if I wanted it to be externally visible, I would have to do 'our package', correct? 14:03
masak Ugator: there has been concrete progress on making Perl 6 modules available on CPAN, AFAIK. 14:05
masak hoelzro: no, package-level things are 'our'-scoped by default. 14:06
hoelzro ok, thanks for the clarification masak 14:07
hoelzro is trying to figure out how package ABC {} is installed from a Moar dump
Ugator masak: what is done in 1to1 ports in regard to naming?
timotimo what is B::? 14:08
masak timotimo: metacpan.org/pod/B
timotimo oh 14:09
masak Ugator: it varies. I've ported modules and given them the same name. I've ported modules and given them a different name. others have done the same.
masak Ugator: as to collisions on CPAN, I don't think that's a big problem -- things will reside in different namespaces from the start. people's searches would probably default to seeing only the Perl 5 modules. 14:10
hoelzro any thoughts on my tale of two compunits? 14:18
FROGGS hoelzro: I started to debug it on sunday evening but did not get far 14:19
hoelzro FROGGS: I was looking a little last night myself
but I'd bet on you figuring it out first =)
FROGGS hoelzro: there must be a symbol merger that runs at deserialization time... if we find it, we can solv that issue me thinks 14:20
hoelzro isn't that the one in ModuleLoader.nqp? 14:21
or a different one?
I noticed that sometimes ABC.WHERE is the same address across compunits, and sometimes it's different 14:22
that confuses me
lizmat commute to AmsterdamX & 14:48
pmurias masak: re not using B as module name, I think it would be confusing if there were both Perl 5 and Perl 6 modules with the same name doing different things 15:09
masak fortunately, no-one is proposing that.
pmurias masak: like if we had a Perl 6 web framework called DBI ;)
masak I agree that would be terribly confusing. also unlikely. 15:10
Ven that'd probably mean we picked very wrong names at some point :) 15:11
.oO( guess what the "bacon.js" library is for?? )
pmurias there is a also a question if the Perl 5 author should own the Perl 6 name by default 15:12
masak that's a good question. 15:13
FROGGS pmurias: since everybody can release the distribution and package Foo, that does not make much sense 15:15
Ven pmurias: I say no :) 15:17
FROGGS pmurias: that's where the recommendation manager would say: "I know this P5 guy, and we recommend to use TAP::Harness by leont, even when there are others that have higher version numbers or more recent patches."
nine Having a P5 author owning the P6 name by default would hinder random persons from porting their favourite P5 module to P6. There's an awful lot of orphaned P5 modules on CPAN.
pmurias everyone can have his own Foo distribution, but if we have multiple ones we need to determine which one is loaded by 'use Foo' 15:18
FROGGS nine: I can release an Inline::Python for Perl 6 right away under my name, and you can do the same under your name tomorrow
pmurias FROGGS: and which one should 'use Inline::Python;' load? 15:19
FROGGS nine: there is no "I register for this namespace, and nobody else can in future"
pmurias: that depends on what version you've got installed
nine FROGGS: on CPAN you can't or at least shouldn't be able to
pmurias FROGGS: that seems like a horrible solution
FROGGS pmurias: if you have installed all dists that exist, a bare 'use Inline::Python' should use the recommended distribution 15:20
nine: when one would use P5's indexer
pmurias recommended by who?
FROGGS nine: but we use our own
pmurias: by the recommendation manager
nine FROGGS: on CPAN?
FROGGS nine: yes
nine FROGGS: where can I find more information about Perl6 and CPAN? The topic interests me. 15:21
FROGGS pmurias: that's why you can/should specify a use Inline::Python:auth<nine> if *you* want to lock it down
nine: S11 and S22
pmurias FROGGS: so someone needs to own the recommended slot
FROGGS pmurias: yes, like P5's indexer keeps a 02packages, we'd keep a list of recommended dists, which would not be that static in contrast to P5 15:22
which means that we can change our mind and switch to a different auth in case the recommended dist is not maintained anymore 15:23
pmurias: so the difference is just: there is no first-come-forever-own namespace thingy, but a list of recommended dists 15:24
pmurias having a first-come-forever-owns-the-default name seems superior
nine But first-come-forever-own is not exactly how CPAN works. One can adopt namespaces.
FROGGS but then again, I can fork TAP::Harness, patch it, and release it under my name... my clone would not just be recommended, but could be installed and used by: use TAP::Harness:auth<FROGGS> 15:25
pmurias having such a thing seems usefull
* useful
FROGGS nine: yes, and we make that adoption more clear, by saying that there is a group of ppl that has the power to decide
pmurias: first-come-first-recommended seems useful 15:26
pmurias what I would like to avoid is some incompatible version taking over as the default name all of a sudden and things breaking 15:31
FROGGS pmurias: the recommendation managers won't change the dist on a weekly basis and won't just pull the rug under your feet
though, when you declare dependencies in your applications/disst, you have to think about what you want 15:32
ugexe raydiak: i dont think your travis run actually compiled any of those modules 15:37
liztormato Re S11 and S22 discussion right now: 15:39
A bare -use Foo- is P5 think in my book 15:40
lucas__ hello channel 15:41
moritz \o
liztormato For production quality code, you will need to specify
lucas__ moritz: o/
liztormato Auth and version as explicitly as possible
That is *the* way to ensure there will be no breakage in production 15:42
masak liztormato: I agree with your point. but surely (a) the system is still opt-in? and (b) in the majority of cases the right version will be chosen if those are not specified?
I agree it's good to be precise. especially auth. 15:43
with version, I can see ways to make the system less robust to changing dependencies rather than more.
lucas__ Sometimes I read something about Perl 6 and CPAN together... Does it make sense? IMHO, code in two different languages on the same repository would be very confusing.
masak lucas__: I for one think it'd be a good thing for both Perl 5 and Perl 6, long-term. 15:44
liztormato If you say -use Foo- you will get the one of the first CompUnitRepo in @*INC that has a Foo
moritz lucas__: you do notice that there's C code on CPAN too? and SQL code? and ...
lucas__ Maybe even JS also... :) 15:44
Ugator should there be a warning, if I specify an old version? 15:45
liztormato Ugator: No
Ugator but this might be relevant for security 15:46
liztormato If your specification is matched by a CompUnitRepo, you get what you asked for
If you don't get what you want, them your specification is wrong 15:47
*then 15:48
FROGGS lucas__: btw, you do not find any Perl 6 dist when you use search.cpan.org or metabase.org... it is just that we use their storage.. 15:49
lucas__: we don't use their websites
liztormato feels the need for an advent post
FROGGS yeah
masak ++lizmat
colomon lizmat++
liztormato Btw: the recommendation manager is only intended for *installation* of dists. Nothing else 15:50
lucas__ FROGGS: What do you mean? Are perl 6 modules hosted on CPAN infra? 15:51
liztormato -use- is about what CompUnitRepo provides
That generally is what is installed
Although the API would allow things such as CloudPAN 15:52
lucas__: Yes 15:54
FROGGS lucas__: yes
liztormato ;-)
FROGGS :o)
lucas__ OMG! :D
I didn't know that.
liztormato Although not limited to
FROGGS lucas__: though, we still use github mostly 15:54
one reason is that the module installer (panda) only has CPAN support in a branch 15:55
lucas__ FROGGS: Yes, I was thinking the github was the only channel of distribution...
FROGGS damn, I need to work at that again :/
liztormato As do I. Will have time Thu-Sun at the patch -p2 hackathon 15:56
FROGGS I won't have time on Sunday, but Sat should work and the evenings anyway 15:57
liztormato Cool. I hope to finish the newio branch in any case 15:58
FROGGS liztormato: fixing CUR::I is also very high on my todo, which is a nice separate task 15:59
lucas__ Range methods are spelled with underscores: excludes_min, excludes_max. Do you think it's ok or they should be hyphenated?
Ven Uhm, how many language have a "minmax" built-in? We do, List::Util (p5) does, ruby does... 16:01
masak lucas__: well, it is by spec...
FROGGS masak: by spec or by design documents? 16:02
masak by synopsis, written by TimToady before the 2009 migration.
lucas__ what 2009 migration?? 16:03
FROGGS lucas__: we migrated the year 2009 in 2004 :P 16:03
into*
masak: what happened 2009?
masak actually, the underscores seem to have been chosen by dduncan: see e35dc603.
colomon is pro-dash 16:04
masak a migration from something to SVN.
lucas__ colomon: \o/
masak yes, feel free to change it to dashes.
but please update S03 also.
arnsholt Does anyone know what the nqp::takeclosure op is for?
FROGGS Dash All The Things! /o/
liztormato Fwiw, I feel that using - is really a dogfooding issue 16:05
FROGGS liztormato: for what? work on syntax highlighters? 16:05
FROGGS arnsholt: public static SixModelObject takeclosure(SixModelObject code, ThreadContext tc) { 16:06
if (code instanceof CodeRef) {
CodeRef clone = (CodeRef)code.clone(tc);
clone.outer = tc.curFrame;
liztormato FROGGS: Also , yes 16:07
FROGGS liztormato: what-else?
liztormato Idiomatic Perl 6 code
FROGGS *nod*
pmurias arnsholt: so that you get a freshly cloned coderef instead of -> {...} returning the same thing every time
liztormato Finding parse issues with identifiers with - 16:08
arnsholt pmurias: Aha. So you need to actually invoke takeclosure on a block to get a closure?
FROGGS ohh, I think our parser is already very good with that
lucas__ liztormato: Are you against this change? 16:09
FROGGS lucas__: no
liztormato But if we break anything, we should know assp
FROGGS pro dash ftw!
lucas__ alright, I'll do it then. rakudo/roast/specs... this will break lots of things, right? 16:10
liztormato I'm pro dash, fwiw
We have deprecation cycle
lucas__ liztormato: thanks. I wasn't very familiar with the term "dogfooding" :) 16:11
Also... do think having only the "negative" is ok, or an affirmative includes_min/includes_max would also make sense? 16:12
*do you (people) think...
*includes-min, includes-max 16:13
well, better not
FROGGS no, we don't need includes-* when we have excludes-* 16:14
liztormato +1
pmurias arnsholt: yes 16:24
liztormato Decaring& 16:25
timotimo liz doesn't care? :( 16:26
masak lizmat: I respect the fact that people like to put dashes in their code. I do have a lot of code bases with exclusively underscores in them, though. 16:27
lucas__ I was thinking range were the only instance of underscores... but grammatical categories and Test.pm also have them... But, well, it's different things, different matter.
masak it's like, some days I do dashes exclusively, and some days I do underscores. the code bases are consistent, but which style they get depends on the day I start them. 16:28
lucas__: those are more OK, I think. they are more internal. YMMV.
lucas__ masak: I agree.
timotimo why don't we tell people to put lots more ' into their functions/methods? 16:35
osfameron why can't you have ' at the *end* of an identifier name btw? 16:38
is that just a parser issue?
timotimo quickly whip up a slang to investigate that idea :)
dalek rl6-roast-data: d636201 | coke++ | / (5 files):
today (automated commit)
 16:44
ugexe in rakudobrew the only difference between the 'build moar' and 'build moar_jit' commands is '--gen-nqp=master'. Is that correct? (last pr from timo removed --enable-jit) 16:45
FROGGS --enable-jit is the default nowadays
bbiab 16:46
timotimo i removed it? 16:46
oops.
in that case, we should either add --disable-jit to moar or introduce a moar_nojit
ugexe 'perl Configure.pl --backends=moar --gen-moar' == 'perl Configure.pl --backends=moar --gen-moar=master --gen-nqp=master' then?
timotimo since moar_jit is now the default
--gen-moar and --gen-nqp will look at tools/build/NQP_REVISION for rakudo and tools/build/MOAR_REVISION for moarvm to figure out which commit to build 16:47
=master will give you the very latest of both
ugexe but on a first build it should generate moar_jit now? 16:48
arnsholt pmurias: Right. That's likely a bug in Snake I'd be scratching my head over =) Thanks!
lucas__ 3 PRs awaiting for you... :) 17:09
travis will break. right? 17:12
moritz travis just builds rakudo, doesn't spectest 17:15
[Coke] moar nojit: github.com/coke/perl6-roast-data/b...oar.sh#L12 17:16
ugexe ill send a pr with nojit option for rakudobrew 17:17
moritz ++ugexe 17:18
timotimo since you can still always turn off the jit via an environment variable, having a jit vs nojit build isn't as important any more 17:32
arnsholt pmurias: Are you sure the takeclosure is needed to get correct closure stuff? Looks like Snake works correctly without it 17:36
timotimo maybe the semantics are slightly different? 17:37
[Coke] ~. 17:39
arnsholt Could be. I'll probably have to pester jnthn about it at some point 17:40
=)

timotimo damn, at one point i really have to stop obsessing so much about performance %) 17:47
arnsholt I think it's a bit early for that. There's still swathes of Python left to implement 17:49
But the whole "Python cannot into declarations" thing is likely to going to be a bottleneck, IMO
moritz timotimo: don't stop obsessing about preformance, please
colomon +1 17:51
timotimo hunting performance can become timesome sometimes 17:55
tiresome*
lizmat the AmsterdamX meeting has started :-) 17:57
lucas__ Should I put "is DEPRECATED" as a method trait or inside the block as a function call? 18:08
I'm copying the example from the recent Increase/Decrease change.
lizmat as a function call 18:09
subroutine traits don't work in the setting :-( 18:10
lucas__ lizmat: Thank you!
Also, I don't understand why Range sometimes uses $.excludes-min and $!excludes-min. Should I delegate to which one?
I guess is the private one, right?
lizmat $.foo is short for self.foo
it subclasses
$!foo accesses the attribute directly 18:11
and does not subclass
lucas__ Oh, so it should be $!foo, right?
I mean... the deprecated methods will delegate to $!foo instead of $.foo 18:12
lizmat generally, yes 18:13

lucas__ Do you like me to change something? 18:18
Similiar thing for excludes_max
TimToady jnthn: 247dc76 makes the XXX hack slightly less egregious, but it could still use to be cachified in the tc somehow, I think 18:20

Fix issue with open(:rw :w :r)
 19:36
lucas__ A little note on the negative/affirmative names on ranges: "not includes" means "excludes" and "not excludes" means "includes". Maybe "not excludes" sounds like a double negation. After doing the deprecated methods, I saw that it would be easy to do: method includes-min() { not $!excludes-min } 19:45
But I'm just thinking... I'm not clear if having both synonyms/antonyms in a language is a good thing.
masak I can sort of see how 'excludes' was the first one that came to mind when writing the synopsis. 19:49
since exclusion corresponds to a '^' at either end.
timotimo right, because we put an extra character to exclude
so "excludes-min?" corresponds to "has an extra character at the beginning?"
lucas__ yes, it makes sense the relationship between excludes and having a caret (^) on the operator. 19:52
I just run in occurrences of !$!excludes-min in the Range code and thought if it would be more easy to think as includes... But this is a minor thing, of course. 19:54
lizmat yeah, we don't want the API to become less understandable for the implementation to become simpler 19:55
timotimo the thing is: accessing $!excludes-min is super fast; calling self.includes-min which calls self.excludes-min and prefix:<!> is problematic because the method call is late-bound 20:00

nine To read Perl, you have to run Perl. That's always been that way. 20:16
How can I access the class' name during role setup? 20:17
timotimo you mean at compose time?
nine yes
timotimo hm, you're looking for something to call where exactly?
nine I'm trying to create a Python class for every P6 class that consumes the PythonParent role. 20:18

timotimo that sounds like you could also write ::?CLASS.^name
masak was gonna say
FROGGS m: sub trait_mod:<foo>(Any, :$foo!) { say $*PACKAGE.HOW.name($*PACKAGE) }; class Bar is foo { }

timotimo FROGGS: not $?PACKAGE? 20:23
FROGGS m: sub trait_mod:<is>(Any, :$foo!) { say $*PACKAGE.HOW.name($*PACKAGE) }; class Bar is foo { }

FROGGS m: sub trait_mod:<is>(Mu, :$foo!) { say $*PACKAGE.HOW.name($*PACKAGE) }; class Bar is foo { }
nine timotimo: yes! Indeed. And I was so close with trying ::?CLASS.name
camelia rakudo-moar 316f99: OUTPUT«Bar␤»
timotimo :)
well, with ::?CLASS you get the type object of the class your code is inside of
FROGGS m: sub trait_mod:<is>(Mu, :$foo!) { say ::?CLASS.^name }; class Bar is foo { }

raydiak in terms of a public api, would it be better to use string params restricted by subsets, or to export constants/enumerations? 21:43
moritz enums, IMHO 21:44
raydiak why?
moritz because they are introspectable
jnthn And more cheaply checkable 21:45
raydiak good points
moritz and once we have coercion types, adding coercions from strings to enum values will be super easy
masak no blog post tonight :/ -- hopefully tomorrow.

raydiak what about naming? worry about cluttering the user's namespace...should you make them type something like (math::symbolic speculation) MS_OP_NODE or MS_VAR_NODE like C, even if it's more ugly and verbose than what you could get away with using strings that don't clobber each other? 21:55
brrt moritz: what are coercion types? 21:56
raydiak or call it OpNode and VarNode and let the user worry about the rare conflict, and easier to type and look at the rest of the time?
raydiak brrt: I think he meant this: perlcabal.org/syn/S02.html#Coercive...clarations 22:02

pmurias raydiak: in Perl 6? using a prefix when namespaces are available seems a bad thing 22:17
raydiak pmurias: so you vote for no exporting at all and make them type Math::Symbolic before everything? 22:18
pmurias I vote for exporting them when there is no conflict and using a namespace when there is one 22:20
raydiak pmurias: ah, or you meant don't worry so much about the naming, because we'll have far fewer conflicts than C?
so just let them explicitly disable the exports and call them in the package when they need to? 22:21
then name them the shorter prettier versions?
pmurias yes
raydiak pmurias++ thank you, I no longer feel like I'm chasing my tail in circles 22:22

arnsholt pmurias: Basically yeah (sorry for the weird language. Too much /r/polandball =) 22:38
timotimo raydiak: if you have a good idea for enums, i'm all ears. in my SDL2::Raw binding i have just named most values without the SDL_TYPE_ prefix and ended up with duplicates :\ 23:46
raydiak well, the basic problem seems to be that constant symbols represent a value, and those values can conflict...while if you use string the problem doesn't exist, because the identifier itself *is* the value that you check against, so nothing to conflict 23:52
idk where I'm going, wandering blindly down "what if" alleys 23:53
timotimo i think i mean something else than you 23:54
there's an SDL_FOOBAR_ASDF and an SDL_BARBAZ_ASDF
raydiak oh right, sorry, you have a different form of naming conflict :) 23:55
