timotimo do watch out, though
for that eval you get the index in the iteration in your $a and the key-value-Pair object in your $b 00:17

gfldex should append treat %_ special? This will cause confusion or bugs. 00:23

camelia rakudo-moar c587b9: OUTPUT«{a => 1, b => 2, c => 3, d => 4}␤»
gfldex thinking about it, it should not just work but warn
TimToady well, do we ever want to allow an append with an option? 00:26
it kinda comes out to the unrecognized option on a method thing again
sena_kun We have a little warning about this in the docs. Perhaps it can be described as a "trap" on appropriate page. 00:27
gfldex %_ can be passed on when wrapping or assuming (if assuming would work on methods)
but I see little use for that outside of constructors 00:28
Hash is kind of a base class and wont pass anything on, at least in .append. So warning their would make sense.

sena_kun gfldex, noooooooo 01:12
gfldex i need to add a way to ignore methods that we don't want to doc 01:13
given I can implement that in Perl 6, that can't be hard. :)
sena_kun Actually, I plan to do a Big Review after we finish compileable examples work. I'm trying to do things a bit quickly here, but I saw some, um, really bad pages and I want to list them all(and learn the docs entirely, what an evil plan). It will be the next todo for me, I suppose. And caching. And offline version of docs. Okay, it's already 4 a.m. here, so I'm going to bed. Good night, #perl6! 01:17
sena_kun About the issues number... There are many pragma-related issues, many of "document this and that" issues, etc. There are not so many big and important issues like dead links and such, so we should be okay with it somehow. 01:20
\quit
Ah.
AlexDaniel gfldex: why me? :) 01:21
gfldex you are real good at adding issues on github. Any as they say: If you are good at digging trenches, you get a bigger shovel. 01:23

TEttinger ha, I was sure I had heard the name z. devito before 05:13
terra's sorta a good thing, sorta very strange
it is embedded into lua code, and lua code uses 1-indexing... but terra uses 0-indexing, since it's closer to C for interop 05:14
so depending on what layer you're in, "the first item" means a different index
they don't have much choice about the lua using 1-indexing 05:15
konobi TEttinger: the code generation and thought process of the underlying peices is really the interesting part to me 05:27

kanl Supply . throttle returns a supply of promises. How does each promise correspond to the original items? e.g. my $s = Supply.from-list( |@a ).throttle: 3, -> $v { do-something-with( $a ) }; $s.tap: -> $v { how-to-figure-out-relation-here() } 07:01
this matters because when running a number of things in parallel, one supposedly would need to know whose promise got kept and whose got broken, not just which. 07:04
i don't suppose it's safe to stick things into a hash inside throttle's pointy block, not knowing it's act() or tap(), Someone care to share, please? 07:15

walkerlala hi there 09:22
anyone online?
tadzik quite a lot of us, yes :)
gfldex Total of 325 nicks 09:23
walkerlala is those on the right side all online? 09:24
AlexDaniel maybe
walkerlala so all of you write perl6 instead of perl nowadays? 09:25
stmuk_ walkerlala: I'm not sure that sort of generalisation is useful and suspectt people use a number of languages 09:26
but yes we share perl 6 as a common interest
walkerlala I am also interested in it. seem like a new language 09:27
AlexDaniel define “new” :) 09:28
gfldex it was made new over a timespan of 15 years 09:28
walkerlala what situation is perl6 in? Is it now being actively developed? 09:30
DrForr Very much so, yes.
gfldex this year is bug hunting year 09:32
walkerlala eh...would it be appropriate if I post some perl5 question here?
AlexDaniel gfldex: wasn't it a performance year?
walkerlala @gfldex why?
DrForr walkerlala: Try #perl on freenode.
gfldex terribad performace is a bug :)
AlexDaniel walkerlala: not really, try #perl instead
gfldex that's one of the Perl 6 repos: github.com/rakudo/rakudo/graphs/contributors 09:33
stmuk_ or #perl-help
gregf_ er, theres perl5 folks here as well ;) 09:34
stmuk_ I think most of the perl people use irc.perl.org rather than freenode
gregf_ freenode #perl is for puns *ducks*
walkerlala gregf_: what do you mean by puns ducks (none-native English speaker asking...) 09:37
gregf_ walkerlala: sorry about that. i was just trying to say that freenode #perl is a bit casual :). but you can sure get help on there as well. as stmuk_ said, irc.perl.org is where the main guys hang out. 09:39
stmuk_ www.irc.perl.org/faq.html suggests 3 channels 09:40
walkerlala Is larry wall still developing perl6? 09:41
gregf_ walkerlala: would'nt want to pollute this channel with Perl5 questions. but, folks should be ok to answer some trivial oh here i would imagine
yep, TimToady is the nick :) 09:42

ab5tract: It's been a while since I used it, but it worked OK back then, aside from issues around precomping things. But I *think* those got fixed since... 17:40
ab5tract jnthn: it may be that it really doesn't appreciate custom BUILD or new?
jnthn Oh, all the way back in January... github.com/MoarVM/MoarVM/commit/7e...ac8d9f74bf
ab5tract: Can't think why it'd trip up over those... 17:41
ab5tract jnthn: yeah, that seems like it might have been my issue. without BUILD or new i seem to regain the ability to construct the object 17:42
i was getting 'Cannot invoke this object (REPR: Null; VMNull)'

ab5tract jnthn: now i'm really curious, because my extended attempt to use it is now failing when trying to call an attribute accessor on the monitor object 18:12

jnthn ab5tract: Dinner won my attention for a while. :) I just fixed and added a test for having a custom method new in a monitor. BUILD is still an issue, however. 19:34
Got some ideas how to fix the BUILD case also...still pondering which one will be least bad. :-) 19:36
ab5tract tailgate: is it clearer? they can take a bit of getting used to, but basically its a 'fancy' way of creating a Callable without entering a new lexical scope
which also allows for niceties in the language design, like creating a multi target that accepts a WhateverCode and passes that WhateverCode its own length 19:38
as seen in .substr
ab5tract jnthn: you've had dinner after only passing *one* of the test cases? ;) ;) ;) 19:41
jnthn: but seriously, thank you for looking into it. you're bug squashing abilities will never cease to amaze me! 19:42
ab5tract man, I don't know how it happened, but over the years I've started to completely fail at the your/you're distinction, after years of being an insufferable nag on the topic. 20:18
perlpilot old age affects everyone differently ;)

ab5tract: also, it always feels like (to me) that these errors creep into my writing because I only think "in spoken language" 20:33
and in spoken language the difference vanishes
jnthn ab5tract: So, now a custom BUILD works in monitor worked too, and I added your case as a test. I also whacked `no precompilation` in until I can track the precomp issue with monitors down and fix it (not tonight... :)), so people won't stub their toe on that issue in the meantime. 20:38

unmatched} Does anyone want to do a good deed? pmurias++'s changes a few days ago removed koality from modules.perl6.org but the column in the db on the site is still there so now it's failing the NULL check on any new module added to the ecosystem. Someone needs to login to www.p6c.org and remove the dists.koality column in /home/modules.perl6.org/modules.perl6.org/modulesperl6.db 22:23
The easiest way is to just toss that file and let the site autogenerate the new and fixed version, but that kills the site for about an hour. Another easier way is to run the build process elsewhere and copy the file over :) 22:24
