MasterDuke `get.Int xx 3` maybe? 00:29

comborico1611 lookatme: Eeek. That's fancy. 00:41
Kaiepi: Nope. I think you dced first.
Kaiepi aight
i have a class with a bunch of nativecall function pointers. is there a way i could more efficiently write wrapper methods for them? hastebin.com/tunesowaxo.pl
comborico1611 MasterDuke: I'll try that real quick. About to need to leave computer. Thanks! 00:42
Oh yeah! Seems to work. Crazy
Goodbye all.

gist.github.com/Kaiepi/a6ce74584ef...d5aa3debd6 00:45
lookatme :( I am on the back of Great Firewall 00:48
Kaiepi i've tried just calling the plain casted function but it complains about not knowing what library or symbol to look for
maybe there's a way to use nqp for this 00:49
seems too complex, i think i'll just cache the sub 00:55
lookatme Kaiepi, what's line 3 mean ? 00:59
Kaiepi applies the role with the signature i want to &cb 01:00
so it knows it's a native sub 01:01
lookatme I am not sure that would work 01:03
Kaiepi it works for me
but anyway i found a better solution
there's a function in the library i'm wrapping that indirectly exposes all the embedded function pointers 01:04

AlexDaniel oh wow, facebook is trying to trick me to enable “Ads Based on Data From Partners” :D 11:24
after a pagefull of explanations on what it is, they have a shiny blue button “Accept and Continue” and a grey option “Manage Data Setting” 11:25
11:26 pmurias joined
AlexDaniel when you click “Manage Data Setting” they give you an extra screen trying to convince you not to do what you clearly want to do :D 11:26
masak AlexDaniel: I'll try to say this without sounding like a raging conspiracy theorist: Facebook is free for its users, because its users are not its customers. those parters with the ads are its customers. 11:27
as a user, you are mainly juicy, profitable data.
AlexDaniel by the way I wonder if the same option is available to people outside EU 11:28
“Thanks for taking the time to review this setting. We won't show you ads based on data we receive from partners. Keep in mind we'll still use this data to provide, personalize and improve our products, to promote safety, security and integrity, … … … …” 11:29
oh so that makes no difference whatsoever, I don't see ads anyway 11:30
masak I wonder how best one can take a stand and safeguard/encourage the web of blogs and podcasts and feeds rather than silo'd communities
AlexDaniel masak: something built on top of Matrix maybe? 11:31
btw there's a Perl 6 community on Matrix with 8 (!!!) people in it 11:32
masak url? 11:33
stmuk_ use the blockchain! ;)
AlexDaniel masak: riot.im/app/#/group/+perl6:matrix.org 11:34
masak looks vaguely Slack-like...? 11:38
I like initiatives like medium.com/message/tilde-club-i-ha...904f0a2ebf
I wish the web/Internet could be more like that 11:39
small, quirky, grassroots initiatives
AlexDaniel masak: yeah pretty much, and freenode is bridged so you can access #perl6 channel from there without really using an IRC client
AlexDaniel` waves 11:42
masak ;) 11:48
real-time chat is fine, but I'm not looking to replace irssi right now
what I'm talking about is something more lasting, on the scale of blogs 11:49
11:49 jmerelo left
masak my strangelyconsistent setup -- markdown files and a build system -- is looking really antiquated in the 2010s. I think I would be better off basing it on something like Gatsby 11:50
AlexDaniel well matrix communities already give you a way to create html pages (dunno how limited though), all you need is the ability to add posts and that would be it… 11:53
masak I already have ways to create html pages, though ;)
doing it within someone else's silo (no matter how benign) is what I'm trying to avoid 11:54
timotimo p6c.org is our own very trendy tilde.club rip-off, except nobody's using it like that yet i don't think
AlexDaniel sure you can always start your own matrix homeserver
masak timotimo: that is a really good point, actually 11:55
timotimo: maybe all I need is a public_html/ directory on there?
AlexDaniel … 11:56
timotimo that is correct
i have one, it works without hassle
it does not have good content yet
oh
i'm apparently wrong about that
masak timotimo: I tried p6c.org/~timo and a few other variations -- didn't work ;? 11:57
:/
timotimo let me briefly investigate
i've got sudo privs on that server, after all
masak how handy ;)
timotimo oh, it's on hack, isn't it 11:58
masak hack.p6c.org/~timo/
whee!
timotimo it doesn't do https ;( 11:59

timotimo oh, is the comment period still open? i haven't written! :o 12:04
Zoffix (trying to avoid people objecting to the changes AFTER they're made :)) 12:05
timotimo: no idea if it's still open, but there are 4 comments: news.perlfoundation.org/2018/04/gra...fixin.html
But comments on the actual work are yeah, still open.
moritz timotimo: currently p6c.org resolves to the same IP as www.perl6.org
timotimo ah, mhm 12:06
moritz timotimo: I don't know what I'd break if I changed that
timotimo it'd probably be fine if we use VirtualHost config blocks to only serve public_html folders of our users if the host is p6c.org, not perl6.org? 12:08
moritz timotimo: those are different VMs 12:09
the home dirs of hack.p6c.org are not available on www.p6c.org
timotimo i know. we'd have to offer access to www.p6c.org
moritz no
Juerd breinbaas: Are you Tim Kuik? :P
moritz we keep that separate for a reason
timotimo or reverse proxy ~foo to p6c.org 12:10
moritz so that perl6.org has a better uptime than hack :-)
perlpunks.de/paste/show/5addccda.3a86.59 fwiw this is the p6c.org zone
Zoffix timotimo: that's how alerts.perl6.org does it. It's hosted on hack, but reverse proxied to p6c.org
moritz timotimo: if it's worth the effort to you, by all means, configure it this way
masak moritz++ # zoning
AlexDaniel stmuk_: by the way, is there a combined rss feed from pl6anet? 12:11
timotimo Zoffix: for web apps, that is totally normal and boring, i'm not sure how often people do exactly what i was proposing, though 12:12
Zoffix AlexDaniel: pl6anet.org/atom.xml

There were three values, 4 2 2. I'm not sure where the 6 is coming from. 14:01

Zoffix Calling lines with argument 3, which is the limit of lines to read
comborico1611 Thanks! I'll put these into my notes in my Perl6 book! 14:07
But I'm left wondering why so many ways to say the same thing.
Zoffix comborico1611: "y so much ways to code the same, dawg?" 14:08
moritz just like human language
Zoffix comborico1611: it's the same way in human languages. Perl mirrors that in some way (the creator of the language is a linguist). And the language's motto is "There Is More Than One Way To Do It"
moritz even python, which has the "there should be one way to do things" mantra, has like 4 ways to format strings 14:09
14:09 raynold left
moritz ... and counting 14:09
14:09 mcmillhj joined
timotimo moritz: "and that one way should be obvious" ;) ;) ;) 14:09
comborico1611 Will one syntax be optimal in one condition compared to another, and that is why both exist? Or is it simply a matter of personal perference?
timotimo actually the mantra is
There should be one-- and preferably only one --obvious way to do it.
Zoffix comborico1611: though the .get xx 3 vs .lines: 3 isn't exactly-exactly the same. I'd expect the .lines version to be slightly faster, since it doesn't need to look up the dynvar three times, for one 14:10
comborico1611: some things are a matter of preference.
you could've written `lines $*IN, 3`
or `lines $*IN: 3` 14:11

avrono it's in local dir called auto ....
Ubuntu 17.10
Zoffix avrono: did you add that path? To auto? 14:27
avrono doh
Zoffix Also, why local dir and not just `zef install IO::Socket::SSL` ?
El_Che avrono: just tested the distro on Ubuntu 17.10 and it works
(using rakudo-pkg, but I think rakudo star will do the same) 14:28
avrono Well when I did zef install ... it keeps throwing an error about unable to locate target
there was an error about ./auto ... so I created an auto dir 14:29
and then it worked
Zoffix avrono: are you still using rakudo you built into ~/rakudo? How come you got /opt/rakudo-star-2018.01/* in your module path?
avrono: do you have libssl-dev installed?
avrono libssl-dev yes 14:30
but /opt/rakudo ... I need to look into
Zoffix What's the full error about unable to locate target?
avrono one sec
CompUnit::Repository install target is not writeable/installable: /home/avrono/workspace/deedee1/auto Need a valid installation target to continue 14:31
Zoffix :S 14:32
weird. never seen that before.
avrono but you are right about the /opt/rakudo ... I wonder if I should just nuke all and start again ..,.
Zoffix But I suspect it might be risidual issues from when you tried to install star as root. I'd try to get rid of all the /opt/rakudo-star-2018.01 stuff
Here's all I got in my module path and I've installed same way as you did (the install into ~/rakudo stuff): gist.github.com/zoffixznet/b33176c...4cfe91ff76 14:33
Yeah, you could nuke. The instructions I gave you the other day were from here, basically: github.com/zoffixznet/r 14:34

mcmillhj_ So I notice that 1 <=> 2 returns Less (as opposed to -1) but it numifies to -1. Is the Order Enum that <=> returns just for readability ? 16:30
Zoffix Well, you could typecheck against that enum 16:31
m: multi z(Less) { say "Order" }; multi z(-1) { say "just an Int" }; z 1 <=> 2; z -1
camelia Order
just an Int
16:32 sauvin joined
mcmillhj_ Interesting. Is there a common use-case for passing an Order to a function? 16:33
I could see there being one if something like .sort expected an Ordering, but that doesn't seem to be the case here. I'm new to Perl6 so just trying to wrap my head around some things 16:36
jmerelo Well, sorting functions should return Order, for instance. 16:37
El_Che jmerelo: testing the repo cretion for regular rakudo for debian and ubuntu
jmerelo You might thing about some map functions doing different things on Pair depending on the Order they receive.
El_Che++ 16:38
Juerd mcmillhj_: In general, magic values are detrimental to readability and understandability of code because they require you to look up, externally, why something is -1 and what that means. An enum is an elegant solution.
mcmillhj_: Yesterday I used github.com/google/diff-match-patch (in Python, because unfortunately there is no Perl version available) and it uses -1, 0, and 1, and I looked them up just to be sure I wouldn't encounter -2 or +42. 16:39
jmerelo El_Che: we might have to use that instead of the current binary option, which is failing too often.
Juerd mcmillhj_: So I'm quite fond of those little enums that make my life a tiny bit easier. 16:40
jmerelo releasable6: status
mcmillhj_ Juerd: sure, I wasn't arguing against using an enumeration. I was asking what other purpose Order serves. It sounds like you can pass an Order to something to alter it's behavior. Which is kind of what I expected.
releasable6 jmerelo, Next release will happen when it's ready. 1 blocker. 263 out of 263 commits logged
jmerelo, Details: gist.github.com/1c625e7f88e02b949e...176bf27c63
jmerelo The blocker just says "JVM build is busted
Juerd mcmillhj_: I don't see a use case for passing an Order yet, because it is the outcome of something, not an instruction. 16:41
AlexDaniel jmerelo: there's a link to the ticket with a bit more info 16:43
jmerelo: we're working on it
mcmillhj_ right, I assume jmerelo meant something like <1 2 3 4 5>.sort versus <1 2 3 4 5>.sort({$^b <=> $^a})
jmerelo AlexDaniel: Yep, I've seen that. Best of luck. Wish I could help. I was just impressed by the message, so laconic, but so true.

El_Che ok, code is sleeping in branch until 2018.04 is out. It will will generate deb repos for Debian and Ubuntu and rpm repos for Centos, Fedora and openSUSE. Alas, no repos for alpine (but that's more of a docker distro) 21:05

jdoege Zoffix: I removed modify_array.t from the test suite and install completes normally. With it included the install process hangs on modify_array.t. 21:11
robertle El_Che: if you want, you can help with the packaging effort in debian itself, rather than create out-of-distro package repos...
the first/current issue is to get it to build reliably on all architectures, after that the main question will be how to suport precompilation during package building or installation and the management of dependencies between the precomp files and moar/rakudo 21:13
El_Che robertle: the scope is different and meant to be complementary. Debian == well integrated OS packages, rakudo-pkg == self contained in /opt/rakudo-pkg, released monthly as Rakudo
robertle: github.com/nxadm/rakudo-pkg/tree/p...ng-systems
robertle right, but how does that work with perl6 libraries? which one would a library package pick? 21:14
I guess you are also hitting similar problems, so I am quite interested!
El_Che I don't think a lib picks a runtime, but the runtime picks a lib
root rakudo-pkg zef installs its libs in /opt/rakudo-pkg, so no problem there 21:15
robertle so your zef would install libs into /opt/ as well?
El_Che user rakudo-pkg zef installs to ~/.perl6
robertle cool
El_Che so if the users uses both runtimes, he'll end up rerunning precomp 21:16
no installation in /usr or /usr/local as debian would
that's for the OS
robertle do you do anything special about precompilation? what if the rakudo package gets updated? Ahow do you re-run precomp?
El_Che perl6 will do the precomp if something changes 21:17
robertle anyway, I should be in bed. but I'll check it out tomorrow
El_Che :)
robertle right, but it might do it as a different user. so suddenly your precomp ends in ~/.perl6 ...
bed now, really! 21:18
Kaiepi do files in resources/ get symlinked to wherever CompUnit installs them to?
for local installs
i'm trying to figure out a way to not have to run zef install . --force-install or delete precomp each time i edit a config file 21:23

timotimo comborico1611: you're saying the return value of the fibonacci sub, but you're not returning something interesting, so just remove the say in the upper part of the code 22:18
comborico1611 timotimo: But I want to print up the numbers as they are calculated.
timotimo that's what the say in your for loop does 22:19
comborico1611 But it misses the first two numbers (1, 1)
Ohh! 22:20
The very first say
timotimo yes, the one above the function definitions section
comborico1611 Yay!
Thanks! I was thinking in Lisp code again.
timotimo i'm sure you already know about the sequence operator, though? 22:21
comborico1611 And that first say must have been a left-over from the previous version of the program.
timotimo that's likely
comborico1611 I may, but I don't recognize the name.
timotimo it's the ... operator
either ... or …
comborico1611 Mmm. Nope, haven't gotten to it yet. Just the range operator ..
timotimo OK
the functionality of the sequence operator makes fibonacci and friends trivial to write down 22:22
rindolf timotimo: hi 22:23
hi all
timotimo you give it a list with starting values, then a function that takes any number of values from the end that it wants, then comes the ... and then some end condition
rindolf timotimo: i imported my proggy to perl6-examples
22:23 aindilis joined
timotimo so for fibonacci, you'll take 1, 1 as the starting values, a sub that takes two arguments and adds them, like -> $a, $b { $a + $b }, and the end can be * to say you want all of them 22:24
rindolf timotimo: it runs fairly quickly but the cpython one seems faster
