hythm_ is it possible to merge two hashes, %h1 and %h2, combining the keys recursively, with %h2 values overwriting %h1 if keys are same?,,, for the above output, %h3 should be: %h3 a => { b => True }, c => { d => False }, e => f => False, g => True }, h => { i => True } 02:57

jmerelo Another SO question with a problem I bumped into today stackoverflow.com/questions/505243...d-identity 08:06
m: say (1,1) === (1,1)
camelia False
jmerelo Related to that above, but also to how set membership works.
08:09 pmmmm left
donpdonp my $a = (1,1); $a === $a => true 08:09
=== is more about pointer equality
(1,1) eqv (1,1) => true
note I know little of what I speak, but I had the same sort of structural comparison question (two Bufs) and solved it with eqv
08:09 stmuk_ joined
jmerelo donpdonp: that seems to be the case; the problem is that set membership seems to be using that instead of eqv or == 08:10
So the strange behavior I point to in the SO question occurs...

Luneburg Is there any way to loop through a string? 15:26
geekosaur you want substr, not indexing
a Str is a single entity, not a fake list
timotimo what you really want is .comb, it looks like
geekosaur or that, yes
Luneburg geekosaur: Thanks, what does .comb actually do though? I can see it adds spacing between the characters? 15:28
jkramer Without arguments it returns a list of the single characters 15:29
geekosaur that's just how a list is rendered by default. it explodes the Str into a list of characters
Luneburg Thanks ;) 15:30
geekosaur you can use .perl to see what the value actually looks like, or use "dd" instead of "say" to get even more internal detail (usually too much unless you're debugging) 15:31

geekosaur (Seq is a read-only, one-shot list; saves memory and garbage collection time for most ephemeral lists) 15:32
b2gills Luneburg: rather than `loop (my $i = 0; $i <= $sequence.chars; $i++) {…}` use `for 0..$sequence.chars -> $i {…}` or better yet in this case `for $sequence.comb { say $_ }` 15:34

lucasb whenever you want to call methods on a new anonymous state var, you have to wrap it in parentheses, right? like ($).foo, (@).bar and (%).baz 17:47
because otherwise it would be interpreted as calls to the object/class the code is inside: $.foo, @.bar, %.baz 17:48
17:48 margeas left
jmerelo lucasb: say what? 17:49
raschipi I didn't see any other idiom to do that, you get to create one.
lucasb *except* when the call is a subscripts, like @.[...] or %.{...}, %.<...>, in this case you are calling on the anonymous state var
jmerelo lucasb: is that documented?
lucasb jmerelo: which part? :) 17:50
El_Che why would you use anonymous vars if you reference the later? Is there an added value there?
jmerelo lucasb: well, pretty much everything...
lucasb ok, let me conclude, then I go back to the raised issues :D 17:51
What I'm suggesting is that syntax like @.[42] %.{'key'}, %.<key> be changed to mean access to the current object/class the code is within 17:52
m: $.foo
camelia 5===SORRY!5=== Error while compiling <tmp>
Variable $.foo used where no 'self' is available
at <tmp>:1
------> 3$.foo7⏏5<EOL>
expecting any of:
jmerelo lucasb: $.foo is syntactic sugar for self.foo 17:53
lucasb obviously, *if* the objects are of the type Associative and Positional, etc.
jmerelo that's probably the reason why you have to put the () around, to disambiguate
lucasb jmerelo: you are correct. the same way @.foo and %.foo also are
jmerelo: correct. and I want that to stay the same 17:54
in things like @.[42] %.{'key'}, %.<key>, it should be required to put () around too!
(@).[42] (%).{'key'}, (%).<key> if you want to access the anonymous state var, otherwise let this syntax mean access to the current self object 17:55
jmerelo lucasb: so what you are saying is try to extend that same criterium to other "bracketing" things, so that $. == self whenever possible. 17:56
lucasb yes, exactly :)
jmerelo so @.[42] would be self[42] if that makes any sense.
lucasb except that there's a problem with "$." being the old P5 special var, so I took it out of the examples 17:57
jmerelo lucasb: OK, it's not a documentation problem then :-), although it might be good if you open an issue with some example where disambiguation needs to be done.
lucasb: old p5 special vars are not really a problem.
lucasb: maybe you should open a discussion in the rakudo repo, after checking what the specification says about that. If it's not specced, it might be reasonably argued. 17:58

Zoffix AlexDaniel++ samcv++ # release 18:01
jmerelo AlexDaniel++ samcv++ and the rest of the team
Zoffix lucasb: why add a gazillion variants of some cryptic syntax? Especially one that's close to anon vars. 18:02
Reminds me of a joke I heard on Twitter: "Perl 6 is what happens when the answer to every bikeshedding session is: 'Let's do both!'"
jmerelo Zoffix: now that you mention twitter... twitter.com/jjmerelo/status/1000069722224852992 18:03
Zoffix jmerelo: what am I looking at?
jmerelo Zoffix: the official extraofficial announcement of perl 6 2018.05 18:04
lucasb Zoffix: my suggestion would make things more orthogonal than they currently are 18:05
Zoffix lucasb: and especially one that's close to attribute syntax that isn't entirely trivial for newcomers to understand. It's quite a lot of mental processing required to discern $.<foo> between anon state var, attribute access or just a method call on self.
jmerelo Zoffix: I mean, if you're looking at that Twitter URL.
Zoffix I don't know why folks use $.foo syntax for non-attribute method calls. Seems like a good way to confuse the reader
lucasb well, maybe folks have a usecase, since self.foo is different from $.foo :) 18:07
They are contextualizers, right? $.foo is $(self.foo), @.foo is @(self.foo), %.foo is %(self.foo) 18:08
m: class { method foo { 1,2,3 }; method bar { self.foo } }.bar.perl.say
camelia (1, 2, 3)
lucasb m: class { method foo { 1,2,3 }; method bar { $.foo } }.bar.perl.say
camelia $(1, 2, 3)
Zoffix lucasb: because it's not just %.<foo>. It's also %».<foo>, %».+<foo>, %».*, %».+, %.&bar and dozens more variants. Which of those would mean `self` and which would mean a static anon? Or will you now force all static var use to use parens? 18:09
18:10 sjoshi left, markong left
Zoffix In fact, when $.+foo syntax was being argued for, I said, no don't add it, because then we'll start going insane. And here we are, proposing more things. And how many people used $.+foo syntax? One? 18:10
lucasb I'm suggesting only method-ish calls
Zoffix lucasb: why the omission then?
This is all special casing: %.<foo> works, but only (as you earlier said) `self` is an Associate and now only with "method-ish" calls, which I don't even know the definition of. 18:11
lucasb currently, %.<foo> always means (%).<foo> 18:12
currently, $.foo always means $(self.foo)
I'm not suggesting *if and only if* classes are Positional, Associative, etc. 18:13
El_Che "it's not just %.<foo>. It'sit's not just %.<foo>. It's also %».<foo>, %».+<foo>, %».*, %».+, %.&bar and dozens more variants" <-- that's what I meant with a big language some days ago :)
lucasb The syntax should be invariant
Zoffix mst: would you be able to add a link to our second logger to the /topic of #perl6-dev #moarvm #perl6-toolchain : colabti.org/irclogger/irclogger_logs/perl6 or give one of the non-op regulars ops so they could do it themselves? 18:14

Zoffix mst: I think it's three different links actually: colabti.org/irclogger/irclogger_logs/perl6-dev colabti.org/irclogger/irclogger_logs/moarvm and colabti.org/irclogger/irclogger_log...-toolchain but the logger people want us to add to the topic before they start logging
AlexDaniel: right?
mst: only in this channel, but not in #perl6-dev, #moarvm, and #perl6-toolchain 18:16
mst ah
18:16 ChanServ sets mode: -v ilogger2
AlexDaniel correct, this channel is fine 18:17
mst Zoffix: right, you now have access to all four to do '/msg chanserv op' 18:18
Zoffix mst++ thanks
AlexDaniel mst++
mst and I stole #moarvm from diakopter and gave jnthn perms there too
if anybody wants anybody else adding, just shout
actually 18:19
mst adds AlexDaniel to all four
AlexDaniel thanks
mst AlexDaniel: well volunteered, my main objective here is that if your bots go nuts you can kick/ban/unban them etc.
samcv thanks for the well wishing of the release :) 18:20

Did it work? Doesn't show up right in the irc logs (and I don't see those chairs in my terminal) 18:24
I mean chars
But I don't see any chairs either
AlexDaniel shows up correctly: colabti.org/irclogger/irclogger_log...05-25#l494

Start rewriting of the hashmap language page

Follows #1682 advice of moving the top-heavy part of the Hash type to this page. That part has been rewritten in similarity to Array, by making references to its general behavior using parallelisms between them. This also goes towards fulfillment of the roadmap #114

Reflows and adds maps info where necessary

Since this document now talks about hashes *and* maps, some sentences must include them. Refs #1682.

moritz IRC logging is a huge privacy nightmare; I might have to stop doing that if the GDPR really hits 18:57
masak :( 18:59
moritz: it strikes me that I've had immense use of the IRC logs over the years. mille grazie 19:00
moritz masak: my pleasure. So far I don't have concrete plans to shut them down, but... 19:01
there are so many unsolved problems 19:02
* GDPR requires explicit consent before processing data. Getting consent from every IRC user is simply impossible
* It's not clear if nick names automatically consistitute personally identifiable information
* It's not clear to me how to process requests for data removal without destroying the whole context of a conversation 19:03
masak right
moritz on the plus side, I'm not logging any IP addresses 19:04
masak are you allowed to mark in some way if a conversation has had messages removed?
moritz I'm pretty sure I do
so I could replace all removed messages with nickname (removed) and line (removed) 19:05
AlexDaniel I wonder what Matrix folks figured out regarding GDPR and their freenode bridge
moritz it gets really murky if somebody has messages (partially) bounced off of bots
AlexDaniel but through that bridge you can't get messages from before you joined the channel
raschipi I'm not logging any IP addresses --> You're required to do that by Brazillian law, btw 19:06
jmerelo The GDPR could potentially affect even bots
If you somehow log whoever is asking and what they asked... 19:07
AlexDaniel rrrrrrrrrrrrrrrrrrriight
moritz raschipi: how charming :-)
AlexDaniel quotable6 actually caches irc logs…
moritz fwiw on the webserver side I delete the last octet of IPs in the logs 19:08
raschipi But Freenode is the one required, not people that archive the messages. 19:09
moritz (and the last 4 bytes for IPv6 addresses)
masak .oO( we're letting you know that your processing^Wprivacy is important to us )

raschipi Anonymity is forbidden by the constitution in Brazil. 19:10
moritz is that why they fought with WhatsApp? 19:11
comborico1611 I find it sadly amusing that nations call themselves republics when they don't even pretend to be. At least in America, we pretend to be a republic.
raschipi Well, not specifically using the Constitution directly, but the laws implement the constitutional mandate saying they need to point which IP adress said what and when. 19:12
With the IP number and the timestamp, after a WHOIS, you can go to the ASN and they need to point which customer it came from. 19:13
s/ASN/AS/ 19:14
moritz ... unless there's a NAT inbetween
raschipi Well, if the ISP keeps the NAT, they need to keep records. If the client has it, that will narrow the investigation to a very small area. And it doesn't deal with a VPN and much less Tor. 19:21
But most people aren't that sofisticated and they regularly inprison people for what they said on the internet. 19:23

At least they don't jail people for their political opinions like the UK does.

you can have a coercive type constraint in the signature, though

camelia False
timotimo m: say "01234567890".comb.grep(^6)
camelia (0 1 2 3 4 5 0)
timotimo is it lexicographical sorting that messes this up? 20:41
m: say "01234567890".comb.grep(45..69)
camelia (5 6)
timotimo looks like
that looks a lot like a trap
ktown i have seen a few example that use $x where ^10 to check an int 0..10, but in a case where I split a string and pass to method it's not happy 20:43
