guifa The framework I’m working on says developers should be able to pass a DateTime, but potentially could pass some formatting arguments but together with the DateTime. They end up having to create an shell class to encapsulate both the DateTime and the format 03:04
Perl6 solution? $date but with-args( week => ‘long’, … ) 03:05
03:06 Cabanoss- left
guifa with-args calls a sub that returns a formatting class that can be matched with ~~ DateTimeFormatter, but everything else ignores it 03:06

Wait, that's not what I wanted, but I'm not sure about how to save a query... 07:34
Anyway, baseline is it's been declining since 2013 and is now at 1/3 of its peak, ~ 300 questions month. Same query on Ruby looks pretty much the same, but peak was in 2015 and is now ~1000 questions/month 07:35

jmerelo perl6 has been (very) slowly increasing to ~ 30 questions/month. There have been as many questions on Perl 6 ever as Ruby gets in a month or Perl in 3 months. 07:36
As a consolation, emerging languages such as Idris or Agda have about half the questions perl6 has :-) 07:37

08:08 wahnwitz joined
wahnwitz hello again :) I have a problem with DB::Pg .. when calling an database action the psql server runs out of connection 08:13
relevant code is here: pastebin.com/TkSK5igv
jmerelo wahnwitz: why are you connecting every time you do a query? Use $pg as an instance variable, and reuse it every tine you do an addDomain 08:14
wahnwitz: you are opening lots of connections and not closing them; you probably need only one. Plus you are doing it using race, theoretically in parallel... 08:15
wahnwitz i see 08:16
08:16 zacts joined
jmerelo wahnwitz: even if you are doing it concurrently, a database should be able to handle concurrent connections. 08:17
wahnwitz mhm.. ok i can open an connection on "new" and use this connector as an argument?
yes it can but backlock is full after a while :)
jmerelo wahnwitz: you are also accessing $db concurrently (via race). Two threads might be fighting for it. 08:18
wahnwitz: right, using a single connection is probably better 08:19
wahnwitz ahh, yes...i was trying to reduce concurrency with batch=>1 assuming there is concurrency in this loop :D 08:20
jmerelo If you want to do it as fast as possible, use channels. Make the loop write to a channel and "start" several threads, every one with their own connection.
wahnwitz: IO.lines is not concurrent. race is.
I don't think race is giving you anything here. But if you eliminate it you're going to get too many connections anyway since you're opening one every line of the file. 08:22
wahnwitz yes
so i would call "connect" together with a new like here? docs.perl6.org/language/objects#Cl...ce_methods 08:23
jmerelo baseline is: too many connections can be eliminated by reusing a single connection. If you want concurrency, you have to redesign the program using a channel and concurrent routines using "start".
wahnwitz i would prefer a single connection for now :D 08:24
jmerelo wahnwitz: like in the pizza example, yes. $!connect would be an instance variable. You would create a single instance of that.
wahnwitz: you might want to consider also Red, the ORM in perl6. In the long run, it's going to save you a lot of SQL writing...
wahnwitz need to learn the basics first ;) 08:26
jmerelo wahnwitz: sure :-)
wahnwitz i dont dig it.. $connect would be a "connector" (in old perlish) so it would the return value from my connect function 08:31
thi swould be $c = Database.new.connect(); .. the second call then $ret = $c.addDomain($c, "sdsad"); .. 08:34
jmerelo wahnwitz: right
wahnwitz my $db = Database.new.connect; Database.addDomain($db, $_, $tld, $id); mhm... 08:41
jmerelo wahnwitz: you don't need to use a class method (Database.addDomain). You don't even need to use $db as an external variable or object. The connection can be an instance variable. 08:42
wahnwitz: above, it would be $db.addDomain( $_, $tld, $id) rather. addDomain is a method of the $db object.
wahnwitz yes 08:43

masak I'm trying to make my (007) test suite platform-independent. what would you folks use instead of shelling out to `diff` and `md5sum`? 08:47
jmerelo masak: I wouldn't? 08:48
masak I found github.com/cosimo/perl6-digest-md5 already, so maybe the `md5sum` part is answered already
jmerelo: yes, but. I need to diff and md5sum things :) 08:49
at least I'm pretty sure I do
jmerelo masak: there's no perl6 diff?
masak: so you get to have at least perl6, right?
08:49 zacts left
masak yes 08:49
I found two modules that return an integer distance between strings 08:50
but the neat thing I get from `diff` the command is that it tells me about the string differences
jmerelo masak: can you have git? It can give you a pretty good diff.
masak hmm
I'd need to at least `git add` things that I don't want to keep -- it feels a bit invasive
08:51 w_richard_w left
jmerelo masak: you can create a repo in /tmp... or you can use porcelain 08:51

masak it feels somehow like I'm building a bigger `git` Jenga tower where my small `diff` Jenga tower used to stand
jmerelo masak: there's git diff-files 08:52
timotimo masak: i often use git diff --no-index
masak hm, I guess I could port metacpan.org/pod/Algorithm::Diff to Perl 6...
jmerelo masak: that would definitely be nice.
timotimo i mean, we do have Algorithm::Diff on modules.p6.o 08:53

no, license, though 08:54

jmerelo kawaii: answered :-) 09:46
timotimo i kind of wish we had more explicit RNG access
currently we only have random state in the ThreadContext, and we can write to it
but we can't, for instance, save away the state and restore it back later
kawaii jmerelo: thank you for such an elegant solution :)
timotimo or have independent RNGs without making additional threads 09:47
and of course when tasks get re-scheduled onto different worker threads, the RNG sequence changes, too, which could be annoying for some use cases

tadzik patrickb: oh hi :) 12:05
patrickb Hi there! o/
tadzik patrickb: I wanted to talk about your rakudobrew changes, I'll be a bit distracted now but wanted to let you know that I haven't forgotten :)
12:06 ravenousmoose joined
patrickb tadzik: Thanks! 12:06
tadzik I'm still not sure why the breaking changes were necessary and what problem are they fixing; I think I asked before but I've forgotten the answer :/
Could you remind me? :)
12:06 ravenousmoose_ left
patrickb Mostly it's cleanup of the and simplification of the directory layout. 12:07
tadzik ah, I remember now; there could've been name colissions, right? 12:08
patrickb One thing it fixes: It's now possible to register external rakudo builds and give them a name. With the versions now in a separate folder the names are guaranteed not to conflict with the other files in ~/.rakudobrew
tadzik right, that makes sense 12:09
patrickb It's not exactly common you would name a version `shims` or `bin` or so, but still possible.
tadzik right, better safe than sorry
and rakudobrew has had its share of both :P
there was this thing where someone symlinked rakudobrew to /usr/bin 12:10
but rakudobrew has a habit of thinking of its bin as its own
patrickb I know. I messed up and mst cleaned the mess up after me.
tadzik so it was happy to rm * between installations or something
oh it was your story! :)
patrickb It was.
tadzik sorry for that :)
rakudobrew was originally intended as something I wrote for myself, published because why not and not accepting bug reports :P 12:11
patrickb We all fail. Important thing is to learn from it...
tadzik it's grown a bit beyond that
I
I'm happy to have you onboard improving it then :)
12:11 ravenousmoose left
tadzik patrickb: alright, so is there an instruction somewhere for the changes required, or is it necessary to do a full reinstall? 12:12
would it be feasible to have some kind of migration option?
patrickb I find rakudobrew quite essential when doing serious work in perl6. Because perl6 still happens to have bugs often. Then being able to quickly switch between the version that works and the latest is important. 12:13
tadzik: Rakudobrew itself will notify the user. 12:14
github.com/patzim/rakudobrew/blob/...dobrew#L18 see here
It's not exactly extensive but says what needs to be done. 12:15
Migration is not possible, because rakudo is not relocatable up until now. Moving the installations breaks them.
tadzik nod nod 12:16
I'm a bit worried that users, who are used to being able to update rakudobrew with no problems will now update it and see a message saying "Well, it's broken now, go delete everything you have before you continue your work" 12:17
so I'd like there to at least be an option to roll it back to some (git tagged probably) backwards compatible version 12:18
patrickb tadzik: The alternative I see is creating a separate repo and continue there.
Ah! That's a nice idea.
tadzik so we can have a git tag called 'rakudobrew-legacy' or 'v1' or whatever, and the message can say "run this and that command to rollback your update to the old version" 12:19
patrickb "If you don't want to reinstall and just keep the previous rakudobrew version, do `cd <path_to_rakudobrew> && git checkout old_rakudobrew`"
tadzik yeah, exactly 12:20
patrickb That's nice. I think we should go that route.
tadzik but yeah, the non-relocatability of rakudos makes migration impossible I suppose
12:20 rindolf left
tadzik but that's not a reason to not move forward :) I'm happy for these improvements 12:20

kawaii jmerelo: I've posted another question on StackOverflow if you've time to give me another suggestion :) 16:16
sena_kun kawaii, don't you want a conversion code for feet&inch? 16:21
or I don't see it, then never mind 16:22
m: my %a = { a => 5 } * 5;
evalable6 (exit code 1) Odd number of elements found where hash initializer expected:
Only saw: 5
in block <unit> at /tmp/WqbcCc9XQD line 1
kawaii sena_kun: I'm already storing an 'average' value for both the imperial and metric heights, what I want to do is take both values and add/remove 10% for my final generated pokemon :)
sena_kun kawaii, I mean, you cannot do "6"5'" * 10, because, well, it is a string of unknown format for Perl 6. Unless you are converting feet&inch to a proper unit, multiply and then convert it back 16:23
16:23 Black_Ribbon joined
kawaii oh wait you're right 16:23
I completely forgot about that
how silly of me 16:24
sena_kun m: my %a = { a => 5 }.map({.key => $_.value * 5}); say %a;
evalable6 {a => 25}
sena_kun and you want something like this
kawaii thank you! but yes you are right, I need to convert the feet and inches into a number before doing this
and then back into a string somehow I guess...
or just.... not use imperial at all
16:25 atweedie joined
sena_kun well, I don't think there are some issues with conversion if you want that 16:25
16:26 lizmat joined
sena_kun just noting that it won't work && multiplying on a hash won't work too. :) 16:26

hythm_ hello, If I have Game Class, which has Player object and Board object, Game asks Player what are the coordinates, Player responds, then game checks Board for the coords and the result either Hit or Miss. How can forward the result back to Player?  so that Player uses the result to set the new coords.  I have created code sample below to explain more what i want to do. 17:57
gist.github.com/hythm7/ac73cdb5e83...fbe8603ceb
jmerelo hythm_: it's probably better if you also use StackOverflow for this 17:58
hythm_: but let's give it a try.
hythm_ can do, but was worried it will be flagged as open question in SO 17:59
jmerelo hythm_: Player does not seem to have any way of being told the result of firing, correct? You don't even store the places it's fired. 18:00
hythm_: we don't do that in Perl 6.
hythm_: In this case you need to rethink the design of Player in terms of what it needs to know and do. If it's going to receive feedback on fires, it needs to store them and there should be a way to refer to them. 18:01
hythm_ alright, will add to SO as well.
jmerelo hythm_: it will probably need to store the cell coordinates where it's hit or not, if it wants to proceed with the game.
hythm_ yes but player does not interact directly with board, its via the game object, so to store the result in player, i need to forward it to player first 18:04
jmerelo hythm_: it will need to have its very own copy of Board. How is it going to decide where to shoot, then? 18:05
hythm_ it knows about the dimension of the board only 10 x 10, and choose from that 18:07
sena_kun hythm_, my gut feeling is that the interaction is likely to be harder than your initial approach is 18:08
hythm_ Im writing SO question and adding the full project link as well
sena_kun you likely want to have a bi-directional relation between Player and Server, so player sends an event "Done X", server processes it and sends an event "Board has changed to state Y, diff is Z", and the player updates its state 18:09
of course, Server and Player might start with dfferent states, for example, for player all items are "Unknown", and the server knows for sure if an item is a target or not, but that's details
but even with turn based games, you still want to have such communication channel 18:10
hythm_ that makes sense sena_kun, any links to server/client communication in perl 6? 18:11
sena_kun hythm_, you mean with network or?
hythm_ not necessarily, i mean something helps with turn based games 18:12
sena_kun for network see IO::Socket::Async docs... that's probably not what you want
hythm_, I'll try to play with it later, I think, and maybe it'll result in a gist. ;-) 18:13
hythm_ thanks :)

jmerelo, i had him code an encoder that goes from gb2312 codepoint to the proper bytes. so doesn't need a lookup table, but shows that they actually are willing to dive into the details of the format 18:36
so very happy i got that email!

timotimo huh 20:22
kawaii at a glance, I have no idea where the fault in my code lies
timotimo the line numbers don't match up exactly with the latest code on github, hold on 20:23
ok, so the first "thing" it's trying to parse is the outermost thing
and it immediately reaches the end of the string, apparently 20:24
could it be you need to subscript the row with [0] or .first to get "an actual string"?
kawaii timotimo: I added the extra method you can't see to the gist, might help a little more

glad that the answer was helpful. \o/
21:31 Manifest0 left 21:32 |Sno| joined
sena_kun hythm_, also, if you want to do more complex things(when there are more than 2 objects), you want to look at some other approaches, because this one grows quickly: for 2 classes you need 2 channels, but for three classes you suddenly want 6, and for four classes with N x M interation you need 12 channels... 21:33
21:34 kaare_ joined
sena_kun so it is an approach that scales horribly, but is pretty suitable for the simple case of two classes. 21:34
21:35 [Sno] left
hythm_ its definitely helpful and is very clear, im sure I will have more questions when I start implementing this on my code, amd it will be more complicated (two players for instance, need to support more than one event (fire, move, sink)... but yes that's very good starting point for me 21:35
21:35 Manifest0 joined
hythm_ yes, once i get a good grasp this approach, i will look into different ones, 21:40
sena_kun +1 for going gradually with it 21:42
