is there some documentation on how this naming convention works in perl6 ? 04:51
if I "use NativeCall" perl6 refer to error on /opt/rakudo-pkg/share/perl6/sources/24DD121B5B4774C04A7084827BFAD92199756E03 04:52
what is this 24DD121B5B4774C04A7084827BFAD92199756E03 ???

robertle perl 6 stores the pre-compiled sources to save time next time around, and they are stored in a content-addressable form. so the 24DD121B... is a hash of stuff to make it easy to look up the file required 05:01

mahafyi i am trying to move up the JS world, through react and into redux, lol. I plan to make site for perl 6 bounties, where people can ask for some problem to be solved if they can pay for it. i'd use it (a lot) myself 05:42
tyil $work is also going to use React in the (near?) future 05:43
but that's for the frontenders, not me :p
on your site idea, while I like the idea, I'm not sure if it'll be used much, as you're dealing with moneys so people generally prefer to use a site with existing (positive) reputation 05:44
I know there's bountysource, but I don't know of any bounty site witha good rep
mahafyi what are existing popular sites?
ah ok 05:45
05:45 mcmillhj left
tyil if you're going to make it, check out Cro :> 05:45
they have a thorough tutorial to set it up with react 05:46
mahafyi yes sure. in fact i came upon redux, from cro docs only, hehe
tyil heh
heh, the post I made is getting downvotes on both /r/python and /r/programming 05:47

mahafyi its crazy, i told someone i am trying to use perl 6 as much as possible, and he said 'no problem using an antiquated stack, but there will be terrible and unique problems for you'
so, i would say it is bias
the mini maxi is , well extraordinary, i am trying to wrap my head around it 05:52

tyil its interesting that people can have this much hate towards something they dont know 05:59
I guess I can think about it positively in that the Perl community is more welcome to differing opinions than the Python community :p 06:00
perlawhirl tyil: cool stuff... i been working on hackerrank probs in p6 too.
tyil nice
do you keep notes about it too? 06:01
06:01 psychoslave left
perlawhirl i did plus-minus like this: xs.grep($_) ÷ @xs for * > 0, * < 0, * == 0; 06:01
yeah, i have been thinking about writing a post about it too 06:02
06:02 psychoslave joined
perlawhirl those haskellrank videos is what originally got me interested, so my solutions are more on the functional side 06:03
tyil that's a nice plus-minus, but a tad too terse for me
06:03 p6bannerbot sets mode: +v psychoslave
tyil that'd be cool to read, I want to become better at functional style programming 06:03
perlawhirl the function argument destructuring comes in real handy for later problems
tyil mahafyi: the Perl 6 solution to mini-maxi?
perlawhirl i didn't even create a sub for mini-maxi... just this: say "{.min} {.max}" with [words.combinations(4).classify(*.sum).keys] 06:05
El_Che mahafyi: I think it's mostly ignorance, not making a distinction between and older language (where the bias applies) and a newer language
perlawhirl that's the whole thing
not all my solutions are so golf-ish
tyil I'd like to see your solutions with explanations, if you have time to write a post about it perlawhirl 06:06
perlawhirl to given an example of the destructuring... for 'bon-appetit' you are given 3 lines, first line has 2 ints n and k, the second line is the bill (a list of ints), and the third line is another int b 06:07
i run my solve function as so: lines.map: *.words.map: *.Int 06:08
and then solve sig looks like this: my &solve := -> (($n, $k), $bill, ($b))
tyil that looks nice 06:09
06:09 khisanth_ joined
perlawhirl so the lines get turned into a list of lists, which then get destructured in the signature into 4 arguments. 06:09
i hope that makes sense... i will definitely have to do a write up
tyil wouldn't you want a @bill though, since it's a list of ints?
06:10 p6bannerbot sets mode: +v khisanth_
perlawhirl yes that works too 06:10
06:11 Khisanth left
perlawhirl i originally went with @bill... but $bill is immutable. so i figure that's more functional-ish 06:11

mahafyi El_Che : i agree, but i did want to participate in the naming / re-naming discussions, as I still on the peripharals of this community. However, this is the second example of this happening in my little world. It may be worth to pursue a name change IMHO. 06:32
06:35 Actualeyes left
El_Che mahafyi: yes, I have had the same experience 06:35
The *only* people that seem to know Perl 6 is a new language are Perl 5 people. We've had many discussions about it in the past, nothing sticked. 06:36
(my statement is not absolute, but my experience)

Ulti tyil: you wrote @ar.reduce(sub ($a, $b) { $a + $b }) is that in preference to @ar.reduce({ $^a + $^b }) ? my personal pref is the latter but Im sort of aware it takes a lot more Perl 6 to know what its doing, but at least quite guessable 08:12
08:13 mcmillhj joined
tyil I went with the former because it's more readable to someone with no experience in Perl 6 (such as Python users) 08:13

ofperfection[m] sent a long message: < matrix.org/_matrix/media/v1/downlo...JNsPuwYnBV > 16:36
timotimo ofperfection[m]: the only thing missing is calling .Str on the result of the smart match operator to get from the match object (which has structure held in it if you have captures and such) to only the string that was matched 16:37
ofperfection[m] perfect, thank you! 16:38
16:38 dakkar left
ofperfection[m] is there a way to parse the output of the match object, such as returning just $0 or $1 16:39
timotimo well, in this case you don't have any capturing groups, so there's no $0 or $1 16:40
otherwise you can either use $0, $1, ... or $/[0], $/[1], ...

16:56 Ven` left
ofperfection[m] if I wanted to incorporate getting ~$0 in the code above, would I do that in the smart match or run a function on the match object 16:57
I'm going to do a simple write up on this probably for other noobs like myself once I've got a better grasp
timotimo you can put it into one line, still

ofperfection[m] Thanks again timotimo, I really am trying to figure it out first. 16:59
ccc Is there a way for a role to "has" an attribute and expect the doers of the role to initialize it? 17:00

17:01 TreyHarris left, p6bannerbot sets mode: +v robertle
timotimo ccc: maybe you can set the default value inside the role to "= die 'must initialize attribute blah'" or something 17:01
ofperfection[m]: you can do the smart match in one line without an assignment and in the next line access ~$0 or $/ or what ever you need 17:02

i.e. $match-object[0]
or $match-object~$0
17:18 lizmat joined
timotimo no, $0 is syntax for $/[0] 17:18

17:25 p6bannerbot sets mode: +v natrys
timotimo it was just missing a semicolon :) 17:25
that's what it meant when it said "missing semicolon or comma?" and put a little yellow triangle before "class Foo"
ccc is there a list of all contexts in the documents? Or is this an ignorant question 17:30
timotimo what do you mean by context?
ccc list context, flatten context ... 17:31
timotimo hm, not quite sure
ccc a state of the compilation where the meaning of a term or epressions "depends"
on the context
timotimo perl6 doesn't do context as much as perl5 does 17:33
functions don't behave differently whether you're calling them in "list" or "scalar" context
instead, you'd coerce the result after the function is done
ccc but junctions behave differently if they're not in a Bool context
timotimo when you .Bool them they'll collapse, yeah 17:34
ccc and there are others scattered all over the documentation
and what I'm asking is there a list of all these kind of contexts
timotimo not sure, i don't have a good idea of the docs 17:35
ccc I gather from what you said earlier that programmers can't define their own contexts (of this kind) other than by using existing "contexts"
17:36 TreyHarris left
ccc meaning there exists a concrete list, which perhaps doesn't yet exist in the documents 17:36
timotimo you can return something that implements a Bool method and a list method and a Numeric method
ccc by constraining the return type?
timotimo no 17:37
ccc then I don't understand what you mean
timotimo m: sub does-strange-things { return class :: { method Bool { say "bool context" }; method Numeric { say "numeric context" }; method list { say "list context" } }.new }; my @a = does-strange-thing; say 5 + does-strange-thing; say so does-strange-thing 17:38

diakopter the basis of your algebra.. like, which axiomatic system for the category theory or the algebra 19:13
I'm merely curious 19:14
ccc I know a little bit about groups, I've played around with GAP (http:gap-system.org)
I'm currently reading (starting to read actually) Semirings http:/www-groups.mcs.st-and.ac.uk/~alanc/teaching/m431/ 19:15
magma (aka groupoid) is a set S with a binary operation (S X S -> S) 19:17

semigroup is an associative magma
group is a semigroup with identity and inverses 19:18
when I say finite, I really mean smaller than some low N since magma will have method associative that is O(N**3) 19:20

AlexDaniel maybe we should also check for ` ` because that's what people mistype 20:03
[Coke]: for example 20:06
docs.perl6.org/language/objects
Everything that is not a native value is an <object> 20:07
[Coke] lot going on at $dayjob, probably won't be able to get to it.
AlexDaniel again no C or I or whatever the writer meant
[Coke] should that be a pod error? 20:08
AlexDaniel I don't think so?
here's more: docs.perl6.org/language/5to6-perlv..._variables
“for more information use <.^methods> to introspect all the above.”
without a test resistance is futile, so not even fixing that… I'll file a ticket instead 20:10
[Coke] ok. I'll peek at it if tuits are ever a thing I have again. :) 20:12

AlexDaniel huggable: star 20:54
huggable AlexDaniel, Estimated Rakudo Star releases: .01, .04, .07 & .10
Herby_ from what I can see, 2018.06 was the last
AlexDaniel Herby_: that's correct, Star is released every 4 releases or so
Herby_ gotcha, thanks
AlexDaniel Herby_: .07 rakudo release was skipped entirely so Star was based on .06, I think the next one will be .10 as planned 20:55

that's easier
lindylex Sorry I was not clear.
I though a word bound would do it.
That did not work.
22:16 p6bannerbot sets mode: +v itaipu
timotimo probably because of what \w matches? 22:17
m: say "-" ~~ / \w /

timotimo so a word boundary won't be matched there

timotimo that's not quite it
lindylex I tried a rand.
range like this one sec.

timotimo ah, i thought ww is the one that only matches if the char before and at the cursor are the same 22:19
but it's called "same"
m: say " .. - ... -- .... --- . " ~~ m:global/ <!same> <[.-]> <!same> /;
camelia (｢-｣ ｢.｣)
timotimo there we go.
that will also match if - and . are next to each other, which may not be what you want
another possibility is this: 22:20
m: say " .. - ... -- .... --- . " ~~ m:global/ <.ws> <[.-]> <.ws> /;

timotimo nope, because - isn't a word char
lindylex "match if - and . are next to each other, which may not be what you want" do not want that. 22:21
timotimo then we'll have to be a little bit more verbose i think

lindylex Why does the quantifier not work?
timotimo since you're not anchoring or have another assertion, it's just fine to match a . that is followed by another .
22:26 TreyHarris joined, p6bannerbot sets mode: +v TreyHarris
lindylex I do not understand this >> [\s | ^] why search for a white space or the beginning of a string with ^ ? 22:27
timotimo because otherwise a . or - at the beginning of the string will not match
if only the \s is there
if the \s isn't there, then . in the middle of other . would also match 22:28
lindylex timotimo : how can I place a single white space in a character class? 22:33
something like this ? <[.-\s]>
timotimo yes, you can, but "a single" doesn't make sense for character classes :) 22:34
