no errors, though :(

notable6 lizmat, Noted!
ZzZombo m: say new Int 07:43
camelia 5===SORRY!5=== Error while compiling <tmp>
Unsupported use of C++ constructor syntax; in Perl 6 please use method call syntax

ZzZombo So why is this a thing? 07:44
sena_kun m: sub new($type) { $type.new }; say new(Int); 07:47
camelia 0
sena_kun though parens are necessary, I guess. 07:48
lookatme_q m: sub new($type) { $type.new }; say new Int 08:49

Unsupported use of C++ constructor syntax; in Perl 6 please use method call syntax
at <tmp>:1
------> 3ub new($type) { $type.new }; say new Int7⏏5<EOL>
lizmat I guess we could lift that with a "no isms <C++>" 08:52
ZzZombo I wonder why is there no "Unsupported use of Object Pascal constructor: in P6 use Foo.new instead of Foo.Create". 08:55
Or for any other language.
lookatme_q There are some prevent you using some syntax such as -> 08:56
I don't know if it fixed 08:57
ZzZombo well, it's one thing to forbid unsupported (invalid) syntax, even tho I don't really agree with mentioning C++ or any other language for that matter. It's another going out of your way to forbid valid syntax just because some other language also uses it (?). 09:00
AlexDaniel it was meant to be helpful in case somebody writes that by mistake… A for effort I guess :) 09:03
lizmat I suggest we implement "no isms <C++>" 09:04
and then consider making "no isms" a default for 6.e
AlexDaniel .e? Doesn't have to be that far I think 09:05
well, as long as there's enough devpower to make that happen earlier 09:06
lizmat please make a ticket: if somebody doesn't beat me to it, I'll do that sometime tomorrow 09:09

lichtkind is there a way in POD do make headings into links? 11:04
Zoffix AlexDaniel: 6.e isn't "that far" really. We won't be waiting 3 years for it. Probably do it yearly, if it's worth it. 11:11
And probably do the work for it on an ongoing basis. Just so there isn't 3000 commits to review by the end. 11:12
And I imagine somewhere by [middle of] October there will be a changelog for 6.d released to users, and that would basically be a cutoff for all 6.d features. 11:13
Switching to "6.e" as our new go-to version for new features isn't a bad a idea :)
Geth doc: 1895af0cab | (JJ Merelo)++ | doc/Type/Str.pod6

Zoffix lichtkind: you'd just use a regular L<> tag, but it might be broken inside =head 11:27
lichtkind Zoffix, i will test 11:30

El_Che moritz: I think it's their business model 12:14
moritz El_Che: still, feedback doesn't hurt 12:17
El_Che: there's a slippery slope where you add an ad, nobody complains, then you add a second ad
El_Che yes, maybe the jobs posting from the same headhunter were always there and the ad for the stickers website was just a trigger 12:18

lucasb is wondering if it would be too unethical to ask for a borrowed PDF copy of this new published book :) 13:49

El_Che "Learning Perl 6" and "Learning Perl, 6 the ed." is somewhat confusing on O'Reilly Safari 14:18
louisono hi, I'm trying to learn perl6 can anybody help me? 14:52
timotimo hello louisono
we have many different ways to learn perl6, depending on how you like to learn 14:53
louisono actually I'm reading a book
timotimo oh, cool, so you've already got something in front of you
louisono Perl6 Fundamentals
timotimo i think i have that in my bookshelf as well 14:53
do you have a particular question? 14:54
louisono yes. At some point in the book's code there a double semi-colon ';;' at the end of a line
I was wondering what it meant?
timotimo if i'm not forgetting something, double semicolons are only ever relevant inside of parenthesis when you're declaring a sub 14:55
so it's probably just a typo
louisono at first i thought it was a typo but then when changing the code the double semicolon happens again at an equivalent place in the code 14:56
timotimo if you remember the page number i can take a closer look
louisono thanks! it is at the end the chapter about testing page 35 14:57
timotimo yes, that looks just like a typo 14:58
it's not a mistake, it's just meaningless there
louisono ok, thanks for your help :)
timotimo moritz: ^ in case that's not already in your bugtracker or what you have 14:59
feel free to stay around or come back for when you have more questions :)
louisono thank you for welcoming newcomers such as me so nicely! 15:00
timotimo \o/ 15:01
moritz indeed, a (harmless) typo that none of my proof-readers has caught
happened twice in chapter 4 (git grep ftw)
El_Che "Welcome to the first edition of Learning Perl 6, a book title that sounds similar to others you may have read and I may have written. This one, however, is my first book about the language called “Perl 6.” I know the name is a bit confusing; I’m not in charge of that part. I’m just the book writer." <-- the first paragraph of Learning Perl 6 :) 15:16
APic ☺ 15:17
ccc_ Checked the Glossary and it's not there. What is an item; what does it mean to itemize? 15:53
p6: say [1,2,3].perl, [1,2,3].item.perl 15:54
camelia [1, 2, 3]$[1, 2, 3]

Does it perhaps have something to do with containers? 15:56

ccc_ thanks lucasb 16:10
Zoffix ccc_: the `(1,2,3) eqv [1,2,3]` is false, because one is an immutable List, while the other is a mutable Array. The item thing places things that are collections of many items (like lists) into a Scalar container, so that the entire collection gets treated like a single entity in things like looping or list flattening. There's an article on containers: perl6advent.wordpress.com/2017/12/02/ 16:19

lucasb (places which could get some design attention before 6.d :)
lucasb I guess the indentation style used in that book has already been discussed here? 16:56
well, nevermind, just a small unfortunate detail 17:00
Zoffix lucasb: thanks for reminding about that misfeature. It was missing the 6.d label on the Issue and yeah, I think it will get an itemizing .item if there's no roast blockage or unforeseen LTAness 17:04
lucasb: yes, that indent style has been discussed and brought up to the author 2 years ago 17:05

Zoffix I don't get the extra "extracting with" lines. It seems to work after the first one: gist.github.com/zoffixznet/f818312...9beec7ad81 17:20
lichtkind_ pastebin.com/nGfXjCjd 17:21
Zoffix No idea what it could be. There's a small chance the dev commit you're using got a bug on it, you could try using a release.

TimToady you can, however, use a subset type there 19:06
when you use a subset type in a signature it automatically splits out the 'where' bits for you
lichtkind tyil strangest thing it just installed 19:22
tyil lichtkind: eh, I guess it's resolved then? :p 19:35
lichtkind im still amazed even pod3html which gave me error msg still odesnt install 19:36
tyil still a similar error?
lichtkind yes
tyil once i have M::MM 0.3.0 out the door i will play with assixt
tyil :D 19:37
let me know if you need any help at any part
also, on your installation issues, I'd recommend making an issue on the zef repo
lichtkind tyil thank you but looks like i should get along, Matrix.gist is just currently broken badly so i have to fix that first, the blocker of 0.3.0 19:39
tyil alright, good luck with fixing it then :> 19:42
lichtkind tyil :) thanks 19:49
Zoffix .tell lucasb but there's no error in that code (other than overobundance of characters). The `a %% b` operator is equivalent to `a % b == 0`, so the code does indeed check for odd numbers: `m: my $number = 3; if ! $number %% 2 { put 'The number is odd' }` 20:57
yoleaux Zoffix: I'll pass your message to lucasb.

yoleaux 20:57Z <Zoffix> lucasb: but there's no error in that code (other than overobundance of characters). The `a %% b` operator is equivalent to `a % b == 0`, so the code does indeed check for odd numbers: `m: my $number = 3; if ! $number %% 2 { put 'The number is odd' }`
lucasb m: my $that = 2; if ! $that %% 2 { say "Hmm... that's odd" }
camelia Hmm... that's odd
lucasb I'll report the errata once I get an accurate page number for that section 22:02
lucasb I think the correct is either 'if !($n %% 2)' or 'if not $n %% 2' 22:05
japhb lucasb: or just 'if $n % 2' of course. :-) 22:34
TimToady we thought about naming the other operator !% in fact 22:41

lucasb ^^ that would be a very orthogonal feature to have! :) 22:55
since booleans are treated as numeric 0 and 1, why not have metaoperator ! and allow numerics to be treated as booleans 22:56

TimToady we just decided that making the ! metaop coerce to boolean was one step too far 23:15

perlBird hello! could somebody potentially help a fellow out with a simple thing ? 23:49
timotimo we can certainly try!
perlBird brilliant! I'm trying to send a post request with a json payload 23:50
using the WWW module
timotimo OK
perlBird and I keep running into an error that looks like so: 23:51
perlBird gist.github.com/cryptobird/4d93135...c0e7a1b95f 23:51
timotimo ah, looks like you're passing the headers as a literal hash, but the subs expect to get it slipped in 23:52
i.e. a bunch of named arguments, or alternatively |%the-header-hash
perlBird that seemed to do the trick!
I was way overthinking it lol 23:53
timotimo hum, but the synopsis looks different
ah i was looking at the wrong one
perlBird now I'm just getting a 400 error, but i expect I just don't understand how WWW wants the JSON to come 23:55
timotimo are you familiar with network sniffers like wireshark? or you can just use strace which is much simpler to get running, but a bit noisier to look at 23:56
perlBird never really used anything of the like 23:57
timotimo do you have control over the webserver you're connecting to? 23:58
perlBird nah, it's just like a ctf thing for an online job posting lol 23:59
