timotimo comborico1611: what birth year would you guess for me? 00:09
comborico1611 I have little context-clues. But I'm assuming you're a little bit older than me, and got onto the computer scene later than myself. So I'd say your 40 years old. 00:10
timotimo i'm glad you're far off the mark :) :) 00:11
i'm just 28
i mean, being 40 years old isn't a bad thing, it'd just be very sudden for me :D 00:12
comborico1611 So I AM older.
And wiser. 00:13
Haha.
timotimo no doubt, i'm lagging behind friends my age in wiseness :| 00:14
not to say you might only be wiser than me because i'm less wise than i should be, of course

comborico1611 Reading the Holy Bible will give you wisdom. 00:15
timotimo i might start studying sacred texts at some point, but now i'm not patient enough to do right by any of them 00:16
comborico1611 I studied religions in my teens and early 20s.
timotimo any stand-outs? 00:17
comborico1611 Stand-outs?
timotimo any of the religions you studied stood out positively to you, i mean
comborico1611 Jesus Christ is the way, the truth, and the life. 00:18
timotimo (second language english can cause you to say some funny things)
comborico1611 Oh! Where you from?
timotimo germany
in fact, i'm going to go to bed very soon 00:19

Kaiepi damn i'm only 21 00:22
comborico1611 Heh 00:23
What do we call a statement that uses the xx operator, as in (say "bob") xx 3 00:25
I'm looking for something equivalent to a for-loop statement, that type of terminology. 00:26
Or is it just, "say bob three times"?
Kaiepi is (say 'bob') a closure? 00:31
wait no, that's a List
00:33 wamba left, pharv joined
geekosaur xx is just list replication 00:34
Kaiepi ohh
p6: dd (say 'bob') xx 3
camelia bob

bob
bob
geekosaur docs.perl6.org/language/control#for 00:35
Kaiepi it looks like it's evaluating say 'bob' while multiplying the List 00:37
00:38 pharv left
geekosaur xx thunks, so it behaves in *some* ways like a for loop 00:39

Kaiepi is there a simpler way of telling if an array is sorted than @arr.sort ~~ @arr? 03:12
Zoffix nothing comes to mind 03:13
ttkp6 Zoffix - thank you :-)
kurahaupo Kaiepi: that's going to take O(n logn) whereas simply verifying that each element follows the preceding one would be O(n)
Zoffix oh, right 03:14

Zoffix Herby_: you've used semicolons instead of commas
Herby_ doh! 03:23
thanks :) 03:24
Kaiepi sorry i was afk 03:25
what are [!after] and [!before] doing? 03:26
Zoffix Kaiepi: that's reduction, basically `[!after] <a b c>` is the same as putting `!after` between each element of that list, as in `'a' !after 'b' !after 'c'` and `!after` is "not after" and `after` is `cmp == Order::More`;.... so basically that statement checks that each element does not compare to be "after" the next one, which in turn means the array is sorted 03:28
I think these are the docs: docs.perl6.org/routine/reduce#(Lis...ine_reduce 03:29
Kaiepi ah
i really need to read the docs on reducing 03:30
in node i abuse reduce a lot 03:31

AlexDaniel I see 09:18
jmerelo AlexDaniel: this paper on concurrent evolutionary algorithms using perl 6 github.com/JJ/evosoft-concurrent-perl6
AlexDaniel: and this other paper on benchmarking evolutionary algorithms and the improvements Perl 6 has had github.com/JJ/2016-ea-languages-wcci (you might remember this one, everyone pitched in) 09:19
AlexDaniel: as you see, I do open science by default. Everyone is welcome to help and obviously add her signature to the paper, if that helps. 09:20
dd070: please check out this answer in Quora www.quora.com/Are-any-companies-pl...use-Perl-6 Also, Edument is developing a whole range of products with Perl 6 edument.se/en/ 09:21
AlexDaniel jmerelo: what's .Rnw? looks like normal LaTeX but I guess it's not? Google doesn't give much… 09:22
jmerelo AlexDaniel: it's Latex + R, using a very cool library called knitr. It allows me to embed data processing and visualization in the paper, and not worry about redoing charts when hated reviewer #3 complains about the font or its size. 09:23
AlexDaniel: also contributes to the open science part. The experimental data and everything is in the repo, and the R scripts show transparently what's being done with it. 09:24
AlexDaniel jmerelo: obviously. That's exactly what I'd expect from any paper really 09:25
jmerelo++
jmerelo AlexDaniel: check it out, it's very cool yihui.name/knitr/ I use it all the time. You update data with new experiments, you only have to rerun
AlexDaniel: unfortunately, it's less popular than you might think among the scientific community. 09:26
AlexDaniel jmerelo: I know
jmerelo: sucks really
jmerelo AlexDaniel: here are a few papers I wrote analyzing several popular Perl repositories, including Moose and Catalyst github.com/JJ/literaturame/tree/master/report Some of them use R Markdown (Rmd), same thing, only simpler. 09:28
The bulk of the data processing is done here github.com/JJ/literaturame/blob/ma...7.Rnw#L25. Anyway, R rather sucks for data munging (or I suck at using it). I generally use Perl for massaging the data, or later Perl 6 09:29
AlexDaniel jmerelo: so how does knitr compare to say tikz? 09:32
jmerelo AlexDaniel: isn't tikz actually for graphics? Also, I think what knitr does is to generate tikz code for the charts. Let me see...
jmerelo: yep, knitr uses internally tikz to generate graphics yihui.name/knitr/demo/graphics/ 09:36

Kaiepi would this be useful to very many people? hastebin.com/afukajibok.pl 11:56
it wraps methods, taking the return value and asynchronously spawning a child process
timotimo Kaiepi: that could be incompatible with precomp, though; trait mods are run at compile time and i don't think locks can be serialized 12:01
Kaiepi damn 12:02
would it work if the locks were handled outside the trait mods? 12:04
wait why aren't i testing this 12:06
timotimo it doesn't seem like @lines is used anywhere, do you only use it to slurp up any output that happens? 12:08
oh, also, i recommend using :bin for stdout and stderr so that it won't crash when the program you launch spits out binary "garbage" 12:10
Kaiepi lines was meant to be returned 12:18
since for what i'm writing i use it for logging
not to console i mean, to irc,which is dealt with separately 12:20
timotimo right
Kaiepi i think using more fp for this might make it possible to do both 12:25

16:52 colomon joined
jmerelo Is there any way to know the plans for implementing NYI things? I'm thinking about all the sprintf flags in this case. 17:00
moritz which plans? 17:02
there is no central intelligence in the Perl 6 projects; people just do what they can and/or like and/or think that it furthers the cause
jmerelo moritz: I don't know. Something like "we're implementing this flag by 20xx.xx". The Y in NYI implies that they are going to be implemented eventually, right? 17:03
Zoffix jmerelo: not really. It's volunteer based and everyone largely works on whatever they want. There are only a few things in plans, like slurpy dispatch would get cached soonish, native dispatch thing will be fixed. If CaR grant is approved, native attributes, rats, and constants would be fixed, but that's about it as far as plans go
jmerelo Is there at least a master list of NYI stuff people can draw from? 17:04
moritz jmerelo: is docs/ROADMAP in rakudo
in a volunteer-driven project, you can either promise release dates or features; it doesn't work to promise both 17:05
jmerelo Let's put it in another way. If I want to be aware of when NYI things are implemented to add that to the documentation (or take out NYI marks), is there a way of doing that other than checking on Roast from time to time?
moritz yes, you can read the rakudo changelogs when a release comes out
they tend to be pretty well-maintained
timotimo have automated tests that change their status when something gets implemented 17:06
Zoffix jmerelo: (master list) not really. There are NYI-tagged tickets on RT but they're outdated and many things I saw in the past aren't planned to be implemented.
jmerelo: well, my hope is the developers who implement those features also document them...
That ROADMAP also looks outdated "Last commit: Sep 15, 2015" 17:07
jmerelo OK, so I see something like a two-pronged approach. Keep an eye on ChangeLog to check what new things that should be documented are implemented, if you want to check particular features, write tests for them and run for new releases, right?

timotimo the bot will only deliver those when it sees someone with the exact nickname speaks up
there was a stackoverflow question where you wanted to edit the text to replace punt with point
the description saying you "fixed a typo" 17:29
jmerelo timotimo: right. So was punt better in that context?
timotimo it fits at least
jmerelo timotimo: let me see...
timotimo: it means "bet" or "take a long shot". "Punter" is sometimes used for "customer". But let me see... 17:30
timotimo oh? 17:31
geekosaur there's also usage derived from NFL where it means kicking it over to <s>the other team</s> someone else to deal with 17:32
jmerelo timotimo: I can't find it. But whatever you did, that's fine :-) 17:34
timotimo can't find what? 17:36
jmerelo timotimo: the thing I edited...
timotimo one of bdf's questions
i think it's the one about tie breakers?

timotimo yes
jmerelo timotimo: Yep, it might make sense if we understand it like geekosaur says. 17:40
timotimo: but then wouldn't that be "punt on"? Or simply punt? english.stackexchange.com/question...-something 17:41
timotimo i've learnt to use it as in "punt to something/someone else" like "refer to" 17:43
jmerelo timotimo: I've restituted it where it belongs. Thanks! 17:45

avrono Trying to build from source on ubuntu 17.10 .... getting ===SORRY!=== No suitable MoarVM (moar executable) found using the --prefix (You can get a MoarVM built automatically with --gen-moar.) Command failed (status 512): /usr/bin/perl Configure.pl --prefix=/opt/rakudo-star-2018.01 --backends=moar --make-install 22:55
any ideas , help appreciated ... 22:56
Kaiepi where's the install/bin dir in /opt/rakudo-star? 22:58
and what command are you running to install? 22:59
avrono failed on perl Configure.pl --gen-moar --prefix /opt/rakudo-star-2018.01 23:00
as written on perl6.org/downloads/ 23:01
installing from source
I could just try the Ubuntu .deb I guess 23:02
timotimo avrono: please be advised that our build system is funky, and you'll require root privileges to use --gen-moar 23:10
instead of that, however, you can cd into the moarvm folder, Configure.pl with the right --prefix, then make, sudo make install 23:11
do the same in the nqp folder
and finally do the Configure.pl in rakudo's folder without --gen-moar
avrono Many thanks ... btw ... many years Perl 5 programmer - best way to get started on Perl 6 ? 23:12
AlexDaniel avrono: we have a bunch of Perl5 to Perl 6 guides here: docs.perl6.org/language.html 23:14
avrono Many thanks again ... look forward to checking it out !
AlexDaniel avrono: also if I were you I'd probably start with this first: learnxinyminutes.com/docs/perl6/
it's a relatively short document and many things you'll know already 23:15
avrono Great minds reading the code now
23:15 mryan_ joined, mryan left, mryan_ is now known as mryan
avrono My fear is 20 years of Perl 5 - old habits 23:16
AlexDaniel avrono: there are some built in error messages designed for these habits :)
m: say ‘foo’ . ‘bar’
camelia 5===SORRY!5=== Error while compiling <tmp>
Unsupported use of . to concatenate strings; in Perl 6 please use ~
at <tmp>:1
------> 3say ‘foo’ .7⏏5 ‘bar’		 23:17
Kaiepi i never used perl 5, but i used nodejs for years
not something i want to touch again
i'll need to learn perl 5 eventually, but i don't think it'll be something i write very often 23:18
AlexDaniel Kaiepi: oh, you used nodejs for years! Great 23:21
Kaiepi: what about a Perl 6 from Javascript guide?
Kaiepi: to go here as well: docs.perl6.org/language.html
we have Haskell, Python, Ruby and Perl5 there 23:22
Kaiepi: but something is missing *wink* *wink* *wink*
Kaiepi it's pretty different, but in a good way 23:23
type system, lexical/function scoping, the complex event loop don't get in the way of writing
i could write a nodejs to perl 6 page, but i wanna wait until i know the language better 23:24
AlexDaniel by that time it will be too late! :) 23:25
23:25 espadrine_ left
Kaiepi lol 23:25
i'll check out the other articles and look into writing it 23:26
AlexDaniel thanks
avrono Not a javascript fan myself , but have used Nodejs since it came out 23:29
I find es6,7,8 unreadable ... async this and that ... 23:30
timotimo perl6 has await without async …
avrono whats the current uptake like of Perl6 ... getting any traction ... ? 23:32
I'm a CTO looking into it for new project
Kaiepi es6 was nowhere near as bad as es5
avrono that's true ... 23:33
Kaiepi (function Foo() { this.bar = 1; } return Foo; )()
intuitive constructors
async/await are good in theory but they still end up leaving you stuck with promise spaghetti in regular functions 23:34
it's starting to get some traction i think 23:35
avrono It's horrid, I've inherited code written in ES6 - written in a functional way ... almost unreadable 23:36
then Flow type thrown in
pointless ... wrong language / style mix 23:37
Kaiepi wdym in a functional way
like full haskell or
avrono yeah - attempted
23:37 robertle_ left
Kaiepi jesus 23:37
avrono a mess
but oddly works somethow 23:38
Kaiepi must be a nightmare to debug 23:39
avrono BTW what IDE do you use for Perl6 ? Atom ? 23:40
Kaiepi vim 23:41
used visual studio code briefly, didn't like it much
avrono ok, vim works for me too 23:42
thanks for the help - going to crack on and pick some Perl6 up ... looks very comprehensive 23:43
Kaiepi i found parts of it a bit tricky at first, but the really easy parts made up for it well 23:45
mainly the module system, how it does oop, and promises 23:46
their flexibility won me over once i understood it better 23:48
avrono I'll check it out ... looks like there are may ways to code with it 23:51
I do like languages like Golang for simplicity and neatness
But Perl Regex has always been great
23:52 Zoffix joined
avrono I need to write a web crawler ... and I hate Python 23:52
Zoffix timotimo: how come that's necessary? "and you'll require root privileges to use --gen-moar"
avrono so either Perl 5 or Perl 6 :-)
Zoffix I think I've built over 10,000 rakudos by now and never once needed root ever....
avrono yeah I just sudo'd it and works fine

Zoffix huggable: atom ide 23:54
huggable Zoffix, github.com/perl6/Atom-as-a-Perl6-IDE also see Perl-6-tailored CommaIDE: commaide.com/
Zoffix avrono: ^ there are some plugins for Atom. And CommaIDE alpha or beta will be out in May
Kaiepi vim has some plugins too 23:55
Zoffix avrono: FWIW, these instructions don't need any root, AFAIK: rakudo.org/files/star/source there are also some pre-built packages: rakudo.org/files/star/third-party 23:57
Kaiepi i don't use root
~/.perl6 is my install dir
tony-o i think github.com/tony-o/perl6-web-scraper still works .. 23:58
for scraping 23:59
