moritz o good morning 06:09
I've just received my royalty statement from my publisher; it seems that the regex book sold 113 print and 14 ebook copies in December when it came out 06:11
I don't quite know what numbers to compare it against to make sense of it, but if 100 people actually read the book, it was worth the effort :-) 06:12
TEttinger you wrote a book on regexes? perl 6 variety? 06:14
moritz sure did: smile.amazon.com/dp/1484232275/ 06:15
and "Perl 6 Fundamentals" sold 76 print copies, 58 ebook in Q4 2017 06:17
moritz TEttinger: seems I haven't spammed enough about it :-) 06:18
TEttinger moritz: could have made a pun on reducing the difficulty of regexes by "seeing through Lenz's Lenses" 06:21
moritz TEttinger: I must say I'm quite happy with the current subtitle :-) 06:29
TEttinger ah, didn't see it 06:36
that is clever
masak noticed the subtitle :) 07:38

scimon So over Easter I think I may have to do something I've been avoiding. Install Rakudo Star on a Windows machine. Yay. 08:18
stmuk scimon: just install the MSI! or use chocolatey which does the same thing and allows other installs as well! 08:55

mienaikage I was trying out rakudo on the microsoft/windowsservercore docker container this morning, might play around a bit more later. Still need to get to grips with powershell 09:20
tyil scimon: just reinstall the machine with a better OS and install rakudo star like usual :D 09:23
El_Che mienaikage: keep us posted on how that works out. Interesting 09:25
scimon It's just my Windows machine at home is really just for gaming. When I develop on it it's generally in a Virtual Machine (or more recently Unity, but that's it's own environment). But I would like to get Proc::InvokeEditor working cross platform so it's useful so I feel I really need ot. 09:47

return type constraints also work for pointy blocks
Well, `htmlify.p6`is what is going to process it anyway... Having a `type` preffix is also a heuristic, because it's where it goes now, as processed with htmlify.p6. Be that as it may, that's fair enough, so I'll accept it anyway. If we change this to some other thing it will go to the pile of links that have to be changed.

perlawhirl hi perlers 13:34
I'm probably going about this the wrong way... but say i want to move functions into their own sub-modules, but still be importable by the user 13:36
is there a better way to go about it than this?
gist.github.com/0racle/a8121cfbb8b...d47ca1861a
ie. without explicitly creating export packages for each sub-module 13:37

timotimo only the https part 15:56
jnthn Was never intended to be happy :) 15:57
(Would be nice to fix that, though)
timotimo really? the site never had https?
jnthn No
timotimo i didn't even realize 15:58
FROGGS jnthn: chrome will get you soon :D
jnthn It's all public content, and I'm not sure illicit Cro use is on any nasty government's radar. :P But it should be easy to add HTTPS. Just a matter of getting around to it. 15:59
FROGGS no, but chrome wants to discourage all none https-sites at some point 16:00
timotimo i do assume you already get downgrades in your search rank if you don't have https on? 16:02
FROGGS likely 16:03
scimon Google is pushing for it heavily yes. 16:04
Zoffix Google's been penalizing for a couple of years already and in Oct2017 they even made chrome cry that stuff' insecure when you enter any content on non-HTTPS site 16:09
jnthn: that's not the only reason to use HTTPS. A malicious attacker can inject "Download CroInstaller.exe" into the page fetched by the user, installing malware to them 16:10
timotimo remember that fun instance where some bank site or something was complaining to a browser (was it firefox or chrome?) that it shows something about being insecure?
and they firmly claimed their site is totally secure
and shortly thereafter - because the bug report was public and surely passed around like an adorable kitty at a children's birthday party - someone hacked the 'site? 16:11
Zoffix jnthn: this thing is easy to use and can hook you up with free SSL in like 2 minutes: certbot.eff.org/
(with cert from letsencrypt)

I'm off, long easter weekend beckons.
tyil I just learned that "Private multi-methods are not supported", is there a particular reason for this? 16:16
also, is there a workaround for this :p
Zoffix IIRC the reason's no one did the work yet 16:17
Zoffix m: class Foo { method !d-i($a) { say "$a is an Int" }; method !d-a ($a) { say "$a is not an Int" }; method !d ($a) { multi z (Int) { self!d-i: $a }; multi z (Any) { self!d-a: $a }; z $a }; method pd ($a) { self!d: $a }; }.new.pd: 42 16:20
camelia 42 is an Int
Zoffix m: class Foo { method !d-i($a) { say "$a is an Int" }; method !d-a ($a) { say "$a is not an Int" }; method !d ($a) { multi z (Int) { self!d-i: $a }; multi z (Any) { self!d-a: $a }; z $a }; method pd ($a) { self!d: $a }; }.new.pd: "x"

hello everyone 17:19
why does this code give me that error? pastebin.com/R4diswbw
I'm trying to make a simple sql select method
my insert method works, but I don't know why the select one doesn't, even though it is modeled directly after the working insert method
say $item.select; 17:20
mst Bowlslaw: your insert method does not return the object 17:23
so $item is not the object 17:24

jmerelo Bowlslaw: insert should return something, if you want to do that with insert. 17:33
Bowlslaw jmerelo: how do i make it return an object?
jmerelo Bowlslaw: just do return. But you should maybe try and do that in a constructor. You can override the default constructor by using submethod new. 17:34
jmerelo Bowlslaw: also, you might want to take db and create-schema outside that class, since they are not working on self. They can be just average routines. 17:35
Bowlslaw hmm
Zoffix Bowlslaw: just put `self` at the end of insert method's body. Right now you're returning the return value of `say`, which is a `Bool` which is what the error is telling you

thanks jmerelo and Zoffix 17:38
jmerelo: how can you tell they are not working on self?
jmerelo Bowlslaw: Well, they are, but they are not actually working on any instance variable. You could change line 23 to just create-schema() and it would work the same, if you also take $!db outside the class. Bear in mind that, in this way, the db handle is going to be an attribute of a particular object. You probably don't want that... 17:42
jmerelo Bowlslaw: or from another point of view, you will have a database handle in every Item object. It's better if you either create a Singleton class to hold that, or simply a global variable. 17:42

Bowlslaw woo hoo! thanks for the help guys 17:57
i got this basic functionality working and I understand more about the design now 17:58
Bowlslaw so all I have to do is expand upon this foundation to implement the other functionality! 17:58
i admit i was quite hesitant to adopt perl 6...
jmerelo Bowlslaw: congrats :-)
Bowlslaw i'm enjoying it now for some reason ;p
it's like a holy child of Haskell, Perl 5, and Scala 17:59
jmerelo Bowlslaw: happy to hear that. To tell you the truth, Haskell and Scala are a bit over the top for me. And the community here is much more welcoming :-)
Bowlslaw yeah, not a fan of Scala, but I think Haskell is quite cool, and their community is super friendly and helpful 18:01
jmerelo Bowlslaw: and smart on top of that. I guess that coming from Perl I found the Perl 6 community easiest. And I still find Haskell a bit difficult to follow. Still, mightily powerful. 18:02
Bowlslaw perl is a lot more useful, in general, than Haskell is, but Haskell really excels at mathematical modeling
if you are curious about Haskell, I highly recommend this book: www.amazon.com/Programming-Haskell...dpSrc=srch 18:03
jmerelo Bowlslaw: you will find that most of the things that make Haskell good at maths are also in Perl 6. First compiler, by Audrey Tang, called PUGs, was written in Haskell.
Bowlslaw: Thanks. I'll check it out.

lichtkind is there any need to announce my class as unit class; ..... ? 19:45
AlexDaniel lichtkind: this way you don't need to indent everything inside :) 19:46
maybe there are other benefits though 19:47
masak no, that's basically it 19:48
masak maybe it also shows some intent, like "this file is for mainly this thing" 19:48
lichtkind you mean without i have only curlies? thanks 19:51
thanks mäsak too good to see you still
your great 19:53
lichtkind can i do types depending on dynamic data? 20:16
Bowlslaw ..what?
lichtkind like subset PInt of Int where * > $g; 20:17
vcv subset PInt of Int where { $_ > $g }; ? 20:22
masak lichtkind: yes, you can 20:24
as long as $g is in scope for the `where`, it's fine for it to change during its lifetime 20:25
lichtkind but not on private attributes?
masak whether it's _sane_ for a type to change dynamically like that is another discussion :)
lichtkind: yes, I think also on private attributes
vcv It appears you might have to put it in a block explicitly? 20:26
lichtkind thanks so much and i think it is sane i do the matrix lib and i want types for basice range check or column and row indeces
vcv I'm guessing something to do with how WhateverCode creates a block for you 20:26
lichtkind indices
Bowlslaw can i do 'multi sub' as well as 'multi method' ? 20:27
masak m: my $g = 1; class C { has $!a where { $_ > $g }; method a { $!a } }; say C.new( a => 5 ).a
camelia (<anon>)
lichtkind Bowlslaw, sure 20:27
masak humm
Bowlslaw: and if you want, you can spell 'multi sub' just 'multi', too 20:28
Bowlslaw :O 20:34
lichtkind masak, no got again: Variable $... used where no 'self' is available 21:11

buggable AlexDaniel, Found 4 results: GTK::Simple, GTK::Simpler, GTK::Scintilla, Inform. See modules.perl6.org/s/GTK
Bowlslaw hmmm 21:40
Bowlslaw I hope Perl 6 fixes Perl 5 biggest weakness: lack of GUI ;p 21:41
needs screenshots
Zoffix Bowlslaw: FWIW there was a recent tutorial posted that goes through building a GUI app: www.tyil.nl/tutorials/perl6-introd...ogramming/ 22:04
Bowlslaw Zoffix: yes, i'm definitely looking into that :) 22:07
Bowlslaw Zoffix: DO you know how one would take the sum of all values of all rows in SQLite? 22:14
for example, this code gives me the total number of elements, instead of the sum of the values: 22:15
AlexDaniel heh, nice use of emoji: github.com/appcypher/awesome-wasm-...d#contents
Bowlslaw my $sth = $dbh.prepare('select price from $table'); $sth.execute; my $total = $sth.allrows; say $total.sum; 22:16
Bowlslaw nevermind I got it 22:28
haha
Bowlslaw sql has a nifty sum function >_> 22:30
timotimo sql is a rather big language full of cool stuff 22:38
Bowlslaw yes 22:40
haha i'm likin my simple app so far 22:41
it accepts items into tables and then can sum up their total prices, select by date, description, etc
now I just need to make some graphs and a nice GUI >_> 22:42

camelia True
Zoffix titsuki_: log is gives a Num, which is floating point math 23:01
Zoffix .tell Bowlslaw well, first `$dbh.prepare("select price from $table")` is an unsafe statement. You need to quote $table properly. I don't use DBIish, but there should be some method to quote stuff (placeholders might work too). As for the sum, `my $total = $sth.allrows».head.sum` 23:03

titsuki_ Zoffx: oh... I just have raised an issue: github.com/rakudo/rakudo/issues/1670 23:04
Zoffix c: 2018.03,HEAD say [log(3/4 * (3/7) ** 3 * 1/14 * 1/14), log(3/4) + 3 * log(3/7) + log(1/14) + log(1/14)]

Zoffix And on HEAD Num stringification is fixed ^ and you can see those are slightly different numbers. 23:05
titsuki_ so should I use "is-approx" even if they are equivalent in mathematically? 23:08
