samcv nice the new warnings for the deprecated names look great a.uguu.se/pSAMBxqa4mY4_Screenshot_...164656.png 00:47
and programs will continue to work but it will give them a warning to change their code. 00:48

timotimo nice work 00:50
samcv timotimo, any idea how long we would deprecate it? 00:52
i don't really care, just curious
00:52 pyrimidine left
samcv don't think anybody is using them 00:54
00:55 inra joined
AlexDaniel possibly until 6.d :| 00:55
assuming somebody was actually using them
and if nobody did, why bother with the error message at all? :)
samcv hm 00:56
idk it's still good policy
whatever i don't really care super much
6.d is fine, or could be shorter idk. i think can be shorter based on 6.c-errata
and CARRIAGE RETURN (CR) and other unicode 1 names are no longer in it 00:57
so it potentially could be shorter
00:57 drrho left
TimToady quick, deprecate the deprecation message, so we can get rid of it in 6.e! 00:58

camelia rakudo-moar f10b09: OUTPUT«{:value(${:thing("test")})}␤»
samcv this is what i want 02:16
geekosaur samcv, you don't, you can't change the value into a hash by changing the shape of the key 02:20
you must change the shape of the value 02:21
(you could change the type so the key can be a Pair or even a Hash, but that won't do what you want either)
samcv the type i can change fine
well i can change the type of $pair's value
so what type do i want? 02:22
geekosaur no, I mean you specify the key type in the hash
samcv how do I do that?
geekosaur but you still can't change the shape of the value by changing the key
samcv i need to pass in parts of a hash to a routine
well to know where in the main hash to put specific things
02:23 Ven joined
samcv so any way to pass in sections of the final structure is fine 02:23
geekosaur that will place things with the key being a hash, it won't split it over a hash of hashes to place things elsewhere
again, the shape of the value is not determined by the shape of the key
using a Pair as a key does not index a hash-of-hashes, it indexes a hash whose keys are Pairs 02:24
geekosaur doesn't remember offhand how the typing of hashes works sigh
samcv well how can I do what I want? i mean i can make the values passed into the sub whatever I want
so i can specify where in the data structure to put it
AlexDaniel m: my $pair = ‘value’ => ‘thing’; my %var; %var{$pair.key} = { $pair.value => ‘test’ }; say %var.perl 02:25
camelia rakudo-moar f10b09: OUTPUT«{:value(${:thing("test")})}␤»
AlexDaniel dunno
why do you have a pair in the first place? :)
samcv it doesn't have to be a pair
geekosaur AlexDaniel, what I understand is they want to specify a path within a hash of hashes of ... 02:26
samcv ^
that
geekosaur so [foo, bar, baz] indexes %h{foo}{bar}{baz}
samcv i'm investigating ways to rewrite the unicode database generation script. so I have agood outline before I start
AlexDaniel cool
geekosaur ah, got the other one but it still doesn't do what you wanted 02:27
samcv getting this to work will make it way more maintainable
02:27 kalkin- joined

geekosaur unfortunately while I know how to write what you want in perl 5, I'm not sure how to do it concisely in perl 6 02:28
geekosaur very definitely still more of a p5 type, as indicated by prior typo >.> 02:29
AlexDaniel I mean, well.
m: my %x = foo => { bar => { baz => 42 } }; say [%x, ‘foo’, ‘bar’ , ‘baz’].reduce({ $^a{$^b } })
camelia rakudo-moar f10b09: OUTPUT«42␤»
AlexDaniel so you just reduce with { $^a{$^b} } 02:30
02:30 user_ left
AlexDaniel does not look like a good solution right, but it works? 02:31
geekosaur does that yield an lvalue?
AlexDaniel not really
well it does, if 02:32
m: %x = foo => { bar => { baz => 42 } }; say [%x, ‘foo’, ‘bar’].reduce({ $^a{$^b} })<baz> 02:33

camelia rakudo-moar f10b09: OUTPUT«Hash %x = {:foo(${:bar(${:baz(69)})})}␤»
geekosaur ok, so pop last component off and index that separately to get an lvalue. looks doable
02:34 labster left
AlexDaniel not the worst thing that I've seen in my code for sure, but I can't really imagine somebody using this 02:34
geekosaur I can, that's why I described it as a path
not the most common thing I've ever done, but certainly one I've needed a few times 02:36
AlexDaniel m: sub path(+@a) { @a.reduce({ $^a{$^b} }) }; my %x = foo => { bar => { baz => 42 } }; path(%x, ‘foo’, ‘bar’)<baz> = 69; dd %x

camelia rakudo-moar f10b09: OUTPUT«Hash %x = {:foo(${:bar(${:baz(69)})})}␤»
AlexDaniel hehe
samcv if you can get a good working example i'll just define a new operator or something 02:37
02:37 Ven left
skids [;] 02:37
AlexDaniel skids: not anymore!
or what did you mean by that? :)
skids m: my %target := fee => { fie => { foo => "fum" } }; %target.perl.say; %target{"fee";"fie";"foo"}.perl.say
camelia rakudo-moar f10b09: OUTPUT«:fee({:fie(${:foo("fum")})})␤("fum",)␤»
skids need a [;]
AlexDaniel :OO 02:38
skids for psuedo-dimensional
geekosaur samcv, that path sub would work fine esp. if you did it instead as a special postcircumfix op
samcv which one should I use?
geekosaur ah. but can you do that dynamically too?
that is, I'm given @path not a static list
(and, without using EVAL) 02:39
AlexDaniel m: my %x = foo => { bar => { baz => 42 } }; %x{‘foo’; ‘bar’; ‘baz’} = 69; say %x{‘foo’; ‘bar’; ‘baz’}
camelia rakudo-moar f10b09: OUTPUT«(69)␤»
samcv yeah i thought about hacking it with eval but that's bad
skids right, we could if I could figure out a dimension-slice constructor, but [;] doesn't parse.
samcv and a terrible solution.
what is this [;]
skids samcv: it would be a reduce-to-list-of-lists, if it worked. 02:40
samcv is ; an operator?
skids (or well, not lol but a dimesional slice)
02:40 astj left
skids m: (1;2;3).perl.say 02:40
camelia rakudo-moar f10b09: OUTPUT«(1, 2, 3)␤»
skids it's a second level comma.
samcv ahhh ok 02:41
and where does that mean that and not end of statement
AlexDaniel I've never thought that it is going to work in a hash
skids samcv: in lists and hash indices
samcv also is there some texas version
ah ok
02:42 astj joined
geekosaur texas version? of standard ascii? (welcome to the land of trigraphs...) 02:42

02:42 Ven joined 02:43 telex joined
samcv i mean second level list operator. but 02:43
AlexDaniel what if you pass it an array that is dimensioned like that
samcv i mean i don't like things which mean different things in multiple contexts
02:43 cpage_ left
AlexDaniel samcv: you're saying that as a maintainer of atom-language-perl6, right? ;) 02:44
skids Note that one should consider what beavior one wants with actual, rather than pseudo, multidimensional hashes.

samcv, Output on both points: (${:bar(${:baz(42)})}, Any, Any)
samcv yea
skids A while back we decided we liked this accidental behavior:
AlexDaniel it's not the stability, the output is just curlified

skids ...and a lot of the multidim stuff was not even considered during the GLR.
So the old idea that a list-of-lists means "go multidimesional" is perhaps old. 03:01

skids I don't know whether to nuke that whole example from operators.pod or find out from the blamees what was going on there. 04:11
geekosaur isn't there still a bunch of stuff from pre-glr (and hypers changed quite a lot in glr's wake)? 04:12
skids All the blames are 2016, but that could've been formatting and tweaks. 04:14
AlexDaniel skids: I don't think it was ever decided
skids Hrm... then there might be a specbugtodo. 04:15
geekosaur most of the docs *are* from 2016, after it was decided to freeze the spec(ulation)s
and do actual docs instead of trying to fix them 04:16
but that means you get docs written from speculations that didn't necessarily happen as such
04:16 hartshorn left
TimToady hyper infixes are supposed to replicate any deficient dimension if the » is pointing that way 04:16
which is what it looks like it's doing 04:17
that's just normal array operations from the APL perspective 04:18
samcv skids, ok so i'm going a different way with this. but need help applying one hash to another. well it's sort of the same problem. but. i guess you could say interweaving two hashes?
TimToady APL is basically always «+» when you say + 04:19
samcv how do i add one hash tree to another without deleting any preexisting ones
TimToady of course, APL doesn't do hashes... 04:20

samcv the print out is {0000 => {NameAlias => {NULL => {type => control}}}} 04:22
{0000 => {NameAlias => {NUL => {type => abbreviation}}}}
${:NameAlias(${:NUL(${:type("abbreviation")})})}
so apply-to-cp gets those first two i pasted, and the result %points{0} is the last line 04:23
as you can see it overwrote it as I knew it would, but I want to be able to get NUL and NULL
if you want to test ftp://ftp.unicode.org/Public/UCD/latest/ucd/NameAliases.txt put it in a folder called UNIDATA one level below the script 04:24
04:26 Actualeyes joined
samcv and it should be able to be generalized to make it so that i can pass it hashes with many different values set 04:27
not just a single one like in this example
skids Ah so you want sort of like Hash.append but not quite. 04:29
m: say { :1a }.append: { :2a } 04:30

faraco NOTE: To upload a Perl6 distribution a target directory whose top level subdirectory is "Perl6" must be specified. In addition, a Perl6 distribution must contain a META6.json. Pause will only consider it a Perl6 dist if these two conditions are satisfied. 04:47
I got the META6.json
but..the top level subdirectory..means? 04:48
do I need to change my lib/Module/Name to Perl6/Module/Name 04:49
uploading to CPAN.
skids Or maybe just stuff the whle module in a Perl6 subdir? I dunno.
faraco yeah, that is question, which part should I stuff them. The whole project, or only the file under the lib/ 04:50
samcv skids, basically what you just said. if i do append i get this: $[{:NameAlias(${:NULL(${:type("control")})})}, {:NameAlias(${:NUL(${:type("abbreviation")})})}]
but i want them to be part of the same
04:52 Ven left
skids Right. But you wat to do it recursively... merge all nonmatching keys, then for all matching keys, create te key and assign it the result of the recursion on the two value. 04:52
samcv yep
exactly
skids I'm not sure there's a "trick" to that other than just writing a recursive sub... hyperops can do some things with matching keys but it'll just get confusing. 04:53
samcv yeah 04:54
the old unicode database gen script just uses references to accoplish it but we have no references in perl 6 04:55
and maybe some other things. but yeah i'm attempting all the big picture parts that need to be in place to begin writing a replacement
only rewrite once etc.
05:03 Ven joined
samcv huh skids it may be simpler than I thought 05:03
m: my %hash = 1 => 'hi'; my %hash2 = 2 => 'hello'; my %new = (%hash, %hash2); say %new.perl
camelia rakudo-moar e7c1d5: OUTPUT«{"1" => "hi", "2" => "hello"}␤»
samcv though may not work for uh. 05:05
skids Well, yeah, just merging simple hashes is easy. It's the multidimensional that's the fun.
samcv m: my %hash = 1 => 'hi'; my %hash2 = 1 => 'hello'; my %new = (%hash, %hash2); say %new.perl
camelia rakudo-moar e7c1d5: OUTPUT«{"1" => "hello"}␤»
samcv yeah that don't work
bleh
i was too optimistic
05:05 pyrimidine joined 05:07 Ven left 05:09 faraco left
skids Basically you can either recurse only for matching keys, or iterate a .unique list of the combined keys of the two hashes into a multisub that only recurses when the keys match. 05:09
samcv yeah 05:10
i'll just make a recursive function I guess
05:10 pyrimidine left 05:12 khw left, bwisti left 05:14 dugword left

fluca1978 how are we going to discriminate a perl5 module from a perl6 one on cpan (I'm thinking about namespace collisions)?
11:51 astj left, astj joined
samcv i mean I would think a perl 6 module installed would only install perl 6 modules 11:51
but. i mean there would have to be some way to distinguish them because there are already many collisions
11:52 pyrimidine joined, Ven joined
pmurias fluca1978: the Perl 6 modules won't be indexed by the Perl 5 tools 11:52
fluca1978 pmurias: right, but that means we are going to have also different versions of search.cpan.org, I suspect 11:53

lizmat yes, but on the other hand, we have --ast :-)
we have PPI sorta built in, no ? 12:04
jnthn Not to mention DrForr's Perl6::Parser work
Also, when the QTree refactor happens... :)
DrForr pokes his nose in. 12:05
jnthn It'll open all kinds of things up
But yes, for now --ast and (probably better) Perl6::Parser are our PPI. And they actually are written in pure Perl 6. ;)
samcv save the trees! 12:06
jnthn :D
pmurias is the QTree refactor planned for the near future?
DrForr Well, there's maybe 5 lines that's nqp, but the rest is perl 6, yes.
jnthn pmurias: My gut feeling is the QTree/macro stuff will end up being in 6.e 12:07
pmurias will QTrees replace QAST? 12:08
12:08 Ven left
jnthn Yes and no. 12:08
moritz I could imagine them replacing a part of the QAST nodes so far
jnthn My current feeling is that QAST will remain the backend inter-lingua.
And QTrees will represent mostly higher-level constructs (at the Perl 6 level) 12:09
12:09 fluca1978 left
moritz that was my understanding as well 12:09
jnthn So it's more like QTree nodes will produce QAST.
Though perhaps in a more pipelined style

Ulti might be the Array.from-iterator stuff 13:36
masak .oO( might be the gremlins )
Ulti yeah its within gremlin level speedup
whats nice though is the times are increasingly rock solid it doesn't jump from one invocation to another which I assume is to do with GC maturing? 13:37
jnthn Ulti: There was a recent improvement that in some kinds of application decreased memory pressure and GC times quite a bit. 13:39
It depends heavily on the use pattern of the application. 13:40
(Some things got nothing. CORE.setting compilation got 20%.)
Uh, 20% speedup and 10% peak memory decrease.
Ulti cool, I haven't actually been tracking memory :< 13:41

lizmat Ulti: the Array.from-iterator does not create a reifier and reification-target now, when it can 13:43
so that's halve the number of objects it used to create always before

lizmat isn't sure either, but creating fewer objects is always a win 13:44

brokenchicken cool :)
rje_ That's the idea anyway. 17:38
brokenchicken and the given {} I guess.
rje_ So $dir.IO is ... ah you're saying there's nothing in the block that uses IO
brokenchicken rje_: no, dir() already gives IO::Paths, so that .IO is a nop 17:39
rje_ I was cutting and pasting in stuff from the chapters.
brokenchicken and the given $dir.IO {} just aliases to $_, so toss the $dir and the given and the $dir.IO; you still got the IO::Paths in the $_
rje_ getting it. slowly. 17:40
brokenchicken and the when {} can be used anywhere, not necessarily in a given {} block. It's possible bdfoy doesn't realize that
rje_ I find I type in three or four different ways to quit the REPL before I try 'exit'.

[Coke] wonders if anyone (aside from [particle] who I haven't seen in years) has setup a DBA or something for Perl 6 support (more in preparation than anything else since there isn't a large footprint out there needing services yet)
brokenchicken wonders what DBA is....
[Coke] "doing business as". or incorporated, or other-wise set up a company. 19:03
masak oh! didn't know that meaning of DBA. 19:09
there's also a :dba directive inside Perl 6 grammars, where it also means "doing business as" 19:10
IIUC it's used to give more cogent error messages when a mismatch happens
of course, in the rest of IT it means "database administrator"... :P

grondilu any French person here? I'm wondering if it's possible to write a regex that would distinguish a 'c' pronounced 's' and a 'c' pronounced 'k' 19:53
probably doable but tough 19:54
raschipi Does it have anything to do with the way vowels are placed arond it?
arnsholt I think that should actually be doable
grondilu yes
arnsholt French orthography is terrible and atrocious in many ways, but IIRC the c is quite deterministic 19:55
grondilu there are quite a few rules. Not many exception, but still lots of rules
arnsholt At least c before vowel
grondilu but if the voyel is 'e', then it's pronounced 's' I think 19:56
raschipi Ça va.
arnsholt [aou] gives k, [eiy] gives s
19:56 raschipi left
grondilu I'm French but I'm actually not sure there is any case where the 'c' is pronounced 'k' before a 'e' 19:56
arnsholt Pretty sure there isn't 19:57
(I'm a foreigner, so we had to drill this shit =)
In fact, I'm not sure if French phonotactics are all too happy with a back consinant like /k/ and then a front vowel like /e/ 19:58
mr_ron brokenchicken: added one more module to provides in META6.json (not sure if right place). Installs with zef on my system now.
arnsholt And I think c before consonant will generally be k
grondilu that's almost certain indeed 19:59
arnsholt And the k before [aou] is pretty set as well, because you use the cedilla when you want it to be s
grondilu eventually googles it and finds www.maxicours.com/se/fiche/7/1/13971.html 20:00
also fr.wikipedia.org/wiki/C_(lettre)#Fran.C3.A7ais 20:01
I should be able to write this mnemotechnic program I'm thinking of, but it will require some work.
arnsholt Right, so no objections to our rules there then
Although the "zinc" example is interesting 20:02
Didn't think of word-final c
grondilu yeah I forgot those
arnsholt For your purposes, you can probably ignore the distinction between g and k
grondilu I doubt it, it seems important for the purpose. 20:03

jnthn mr_ron: Just had a quick glance at the module; I think putting those tokens in a role would be more natural
So they're easily composed into other grammars
mr_ron jnthn: will do but don't understand why role is better than simple inheritance ?? 20:29
jnthn Because if I am composing my grammar out of various pieces I'll have a chance to find out about conflicting tokens
Whereas with inheritance I get...whatever is first in the C3 MRO 20:30
Which is less simple to reason about :)
dugword inheritance is fine when you have a single sub class, but it gets really murky and awful once you start doing multiple inheritance. Roles are much more easy to compose
20:31 grondilu left
mr_ron thanks ... will try to research further and make the needed changes 20:31
20:31 troys is now known as troys_
dugword www.youtube.com/watch?v=cjoWu4eq1Tw A good video on the subject. He uses perl5 moose but the object system in perl6 is very similar 20:32
arnsholt "Not as advanced as the stuff Damian or jnthn puts out, but also not as funny." ^.^ 20:34
mst mr_ron: because a role is simpler than inheritance. 20:38
DBIx::Class leans very heavily on the C3 MRO, and it's a ridiculously powerful approach, but roles are much easier to reason about and debug 20:39

arnsholt Given that Ovid just mentioned C3 in that video: "I find [it] about as useful as an icepick on the Titanic" =) 20:40
Possibly with a "usually" mixed in
samcv do we have a good YAML parser?
i saw there is one but I have not used it yet
20:40 vendethiel left
mst arnsholt: well, yeah, he had a lot of trouble understanding roles, and C3 is significantly harder 20:41
I've seen classes he wrote that compose in ten or fifteen roles, all of which are just bags of utility functions
those are ... interesting to unpick 20:42
usually into a mixture of imported subroutines and delegation to sub-objects
jnthn samcv: I used it in $dayjob project. My main complaint is that it's not got good error reporting.
arnsholt Ow. That sounds a bit over-eager in its application of roles =) 20:43
samcv 0 bytes to the right of the data structure. uhm.
arnsholt samcv: Just outside of the bounds
jnthn So if you write correct YAML life is good. :P
samcv ok then i know what the problem probably is
mst arnsholt: yeah, I mean, it's a common programmer failure mode
I mean, perl5 programmers usually have a stage where they go "ooh lots of syntax, let's use as much of it as possible" 20:44
then they discover Moose and try and meta ALL the things
samcv i think this cropped up when I stopped using an int i in the loop and declared it above. and iterated down instead of up
arnsholt True, true
samcv so that makes sense
RabidGravy ah, arnsholt github.com/arnsholt/Net-ZMQ/pull/9 if you have a moment
mst I didn't fall down that particular rathole with roles, but I've fallen down most of the others
and by the time I got to roles, I modeled them as 'C3 MI except comprehensible' so I suspect I'd already shot my foot off a couple times with MI and that informed my choices 20:45
samcv yeah this ASAN report it's 8 bytes and 0 to the right, so it's probably accessing the pointer. 20:46
would be nice if ASAN said, XX is starts 0 bytes to the right of YYY 20:47
would be more clear

DrForr Interesting buglet I just caught - Errors that are truncated like "List ($(Long::Type::Nam...)" don't balance thei parens. 20:53
Should "really" be "List ($(Long::Type::Nam...))" IMO, at least to keep editors happy. 20:54
moritz the times we live in... today we needed a MicroSD card for a mobile phone, just to get some pictures to a cheap feature phone. My wife asked what size, and I said "the smallest. Or cheapest" 20:55
she came back with a 32GB MicroSD card, because it was the cheapest. 5€.
DrForr Scare-quotes around "really" because of course that requires the truncator to be much smarter, and balance its output when "needed". 20:56
moritz and I remember when I first had my own computer, with only floppy discs to exchange data between my PC and the PC with internet access
RabidGravy yeah, I've got a bowl here full of 2GB ones,
DrForr They give away 32G cards in the RPi bags, back when I was buying my DSLR I only got an 8Gb because it was the largest I could afford. 20:57
RabidGravy I tried to get am 8GB usb drive a few weeks ago, no deal, had to get a 32
21:00 bjz left
RabidGravy on the other hand I do have at least one device that balks at a 16GB CF card, which is a pain as the 4GB ones are hard to get and more expensive 21:01

jdv79 so it looks like i have supply { loop { emit() } } and emit doesn't seem to do anything 21:21
but remove the loop {} and it works
brokenchicken umm.. what does it emit? 21:24
El_Che are all modern democracies about delegating power to a prince for a time? 21:25
brokenchicken like what's the actual code 21:26
El_Che oops 21:27
jdv79 i'm golfing it
El_Che ignores El_Che
21:30 nicq20 left
jdv79 oh, i think its because its .act'ed 21:32
and the loop never ends
i lifted the loop and used .tap and it seems happier. thanks . 21:33
brokenchicken Why would that matter?
it's only executed until an emit 21:34
[Coke] rant: can't easily convert comments on commits into github tickets. 21:36
mst: converted your comment into a ticket so someone can act on it.
mst [Coke]: ta 21:39

brokenchicken I have the strangest of problems: I'm failing at turning on the air conditioner because the motor is frozen solid. 21:51
21:52 ssotka joined
jnthn If it's so cold, why do you need air conditioning? Or does the conditioner also provide heating? 21:53
timotimo just make it cool the outside 21:55
brokenchicken Haha! Because the heating in my apartment is so damn hot that sometimes it's way too hot in my bedroom, despite the balcony window and doors open... So how come I don't just open a window in my bedroom? It's cause there's barely any window sil on it and I'm on the 8th floor, with a parking lot below it. Fearing the aircon would fall out, I essentially glued it into the window with expanding foam. So what the
hell was I thinking when I did that? I thought, "hey, the 'fan-only' setting on this aircon surely sucks the air from the outside" but no, the fan-only setting just circulates the air inside for no reason.
So once in a while I run the aircon in my room for a few minutes, but last night I forgot about it and it ran for awhile, generating a lot of condensation that now froze :P 21:56
I managed to make it turn now, but looks like there's a chunk of ice on the fan, making it unbalanced and noisy :P
timotimo yikes 21:57

jeepc Hi, I still have a question on perl6 grammar. I have an issue with simple quote. My testcase is gist.github.com/anonymous/fa686cee...f5d9116a5. I don't understand why simple quote are not captured by the regex <expr2txt> defined as {:s .+} 22:04
I tried to give complete explanation with the code ... 22:05
Thanks for your help.
brokenchicken jeepc: prolly 'cause rules don't backtrack. Change expr2 from rule to regex 22:09
22:09 espadrine joined
brokenchicken recalls a wise voice saying backtracking in grammars is a smell... 22:09
jeepc Many thanks. 22:10
I'm checking.
Of course, this is perfect. Many thanks for your quick help. 22:12
DrForr As a side note - I'd generally stick with {rule,token} names inside a grammar, just as a style thing.
And [<foo>]* is easie to write as <foo>*. 22:13
jeepc You are right
DrForr In the longer term, <expr1> and <expr2> will probably merge into one term. 22:17

moritz and if you want to parse a quoted string, the inside usually parses as <-[$delimiter]>* 22:25
much better than .+ and backtracking
