ipatrol AlexDaniel: can you amend the commit to link to my github page? 00:05
github.com/ipatrol
raschipi Soon Zoffix will get you to work for him. 00:10
ipatrol lol 00:14
Anyway, is there a way to have one hash partially overwrite another, similar to push(), but without the array semantics? 00:15
raschipi Yes 00:16
ipatrol raschipi: which is...? 00:18
raschipi No idea.; I just remember there is a simple way.
It's common for people to ask in the channel. I don't remember what the solution is, though. 00:19
ipatrol raschipi: python has dict.update(), I can only presume P6 has something similar
raschipi Let me think about it for one minute more. 00:20

grondilu Is there a simple way to "negate" an Order? 00:21
lol nevermind I can just reverse the arguments
:P
(silly thing is : that's what I did, but I forgot I did it :/) 00:22
00:22 headcase left
raschipi ipatrol: Maybe %h{%g.keys} = %g.values ? 00:23
grondilu can you rely on them being in the same order? 00:24
raschipi Yes, it will call sort beforehand.
timotimo not sure if .keys and .values are always guaranteed to be in sync? 00:25
grondilu you may need a prefix:<|> though
raschipi Worked for me without the slip
ipatrol m: %h = 'a'=>'b','c'=>'d'; %g = 'f'=>'g','c'=>'e'; %h{%g.keys} = %g.values; say %h;

raschipi how do I ask the bot to link source? Most compli9cated bot ever that one

grondilu evalable6: help
evalable6 grondilu, Like this: evalable6: say ‘hello’; say ‘world’ # See wiki for more examples: github.com/perl6/whateverable/wiki/Evalable
raschipi SourceBaby: help
SourceBaby raschipi, Use s: trigger with args to give to sourcery sub. e.g. s: Int, 'base'. See modules.perl6.org/dist/CoreHackers::Sourcery
grondilu lol I found the evalbot help on first try :)

ipatrol raschipi: at any rate, it seems like something that ought to exist as a method. Perhaps a feature request is in order? 00:27
timotimo m: my %h = :1a, :1c; my %g = :2a, :3g; my %comb = %h, %g; say %comb
camelia {a => 2, c => 1, g => 3}
timotimo this is probably more correct
raschipi ipatrol: It does exist, I just don't remember what it is.
ipatrol timotimo: that would be a non-destructive way to do it, apparently 00:28
timotimo well, you can also %h ,= %g 00:29
m: my %h = :1a, :1c; my %g = :2a, :3g; %h ,= %g; say %h
camelia {a => 2, c => 1, g => 3}
timotimo ^- there you go
raschipi there it is, told you ipatrol
thanks timotimo 00:30
ipatrol so the comma operator joins hashes?
raschipi ope, comma operator builds lists 00:31
nope*
ipatrol raschipi: normally, but I take it in hash context it will join hashes?
or more precisely, it turns both hashes to lists of pairs, makes a list of each of them, and when one then assigns that nested list to a hash container, it is then flattened? 00:33
timotimo that's how i assume it goes, yeah
raschipi Not the comma operator
The asignement to the hash does that
ipatrol m: my %h = :1a, :1c; my %g = :2a, :3g; say %h, %g; 00:34
camelia {a => 1, c => 1}{a => 2, g => 3}
timotimo yes, the list assignment part is the important bit
00:35 headcase left
raschipi m: my %h = :1a, :1c; my %g = :2a, :3g; dd (%h, %g); 00:36
camelia ({:a(1), :c(1)}, {:a(2), :g(3)})
00:36 Cabanossi left
ipatrol would love a debug mode that will tell you what is the canonical equivalent, in terms of explicit function calls, of whatever was just executed 00:37
raschipi Not everything can be done with function calls
00:38 Cabanossi joined
raschipi OPerators don't need to map to function calls. Some are even special cased in the compiler and there would be no way of doing what the do with function calls. 00:38
timotimo a desugar module would be nice
i'd say it'd be fine to "bottom out" in those cases without making it any simpler 00:39
ipatrol right, what timotimo said
grondilu what's the syntax to make a unicode character from its english description?
00:40 headcase joined
ipatrol \c[NAME] 00:40
grondilu oh yeah, thanks
timotimo there's also a function for that 00:41
ipatrol \c[YOU ARE WELCOME]
MasterDuke ipatrol: it's not quite exactly what you said. but if you use MVM_COVERAGE_LOG=<something> and MVM_COVERAGE_CONTROL=1, you could put an nqp::coveragecontrol(1) right before the part you're interested in and nqp::coveragecontrol(0) right after 00:45
ipatrol MasterDuke: I have no idea how one would even go about doing that
are those pragmas or something? 00:46
MasterDuke and the log would show you what lines in the rakudo source are being executed
environment variables
AlexDaniel ipatrol: aw yeah, should've use “@ipatrol” to link it automatically. I guess it's too late now, but will do next time :)
ipatrol AlexDaniel: I know you can amend commits in git
AlexDaniel last commit yeah, two commits deep requires some kind of rebase magic 00:47
I have a better solution, hold on
raschipi Not when they are merged upstream
In local only commits, that's possible.
AlexDaniel raschipi: you can still force-push it, not that big of a deal for small repos like whateverable 00:48
timotimo git rebase -i origin/master will let you change a "pick" to "reword" and then it'll let you rewrite the commit message and you'll still end up with all commits you had in the same order
if you have already pushed it, you can use a different commit from origin/master, like HEAD~4 or so
raschipi Right, it's only a problem is a fork pulls it.
grondilu say I have two types Foo and Bar and I defined multi infix:<leg>(Foo $, Bar $). I shouldn't have to define multi infix:<leg>(Bar $, Foo $), shoud I? I mean, can't I use the antisymmetricity or something?
raschipi if a fork*
MasterDuke `MVM_COVERAGE_LOG=<something> MVM_COVERAGE_CONTROL=1 perl6 -e 'use nqp; my %h = :1a, :1c; my %g = :2a, :3g; nqp::coveragecontrol(1); my %i = %h, %g; nqp::coveragecontrol(0); say %i'`
something like that ^^^
timotimo grondilu: it won't do that for you, i don't think 00:49
grondilu well, that's LTA
00:49 headcase left
grondilu can't someone write a "is antisymmetric" trait or something? 00:49
no seriously it's LTA. If there is a candidate for foo leg bar, but none for bar leg foo, it should fall back on the former to define the latter. 00:52

ipatrol $ipatrol.ACCEPTS($AlexDaniel::apology) 00:59

raschipi ipatrol: That's better written as '$AlexDaniel::apology ~~ $ipatrol' 01:00
ipatrol ordinarily, but sometimes, explicit is better than implicit :-P 01:01
raschipi I think I know what you guys wanted above, a way for the debbuger to print which functions are being called?
ipatrol raschipi: some kind of desugaring apparatus
raschipi so, to know $AlexDaniel::apology ~~ $ipatrol calls $ipatrol.ACCEPTS($AlexDaniel::apology), you'd want thew debugger to go into it... 01:02

u-ou what does proto do? 05:48

geekosaur sets up for what C++/Java call overloading (multiple definitions distinguished and dispatched based on different signatures) 05:52

geekosaur actually that is multi, not sure how proto fits in with that (actually the combination seems slightly odd tbh)
u-ou but you can't have one without the other? 05:59
geekosaur that is what is confusing me. proto is something I think fo as being in the declaration for each impl because that;s how they're dispatched
05:59 headcase joined
geekosaur so a single common proto seems contradictory to me as it implies no way to dispatch on proto 05:59

well, the doc I just read implies what I said was right... 06:01
ah, it allows abstracting out a common core
including common code, apparently, by providing a body with {*} where dispatch to the specific candidate should happen 06:02
06:04 headcase left
geekosaur so, given that, brings me to what I was thinking of about it: it was degtermined that letting the return type specification be obeyed at all implies return type polymorphism (a la Haskell typeclasses), which has been rejected 06:04
but in that case it should probably at least warn
also the docs say nothing whatsoever about the return type, but: "It acts as a wrapper that can validate but not modify arguments." 06:05
implying it doesn't act as a normal declarator at all
so, might be worth a LTA bug (although I am not sure if it should error or warn) 06:07

piojo I noticed we have 3 pages about OOP, which come at the problem from different angles. Typesystem, Object Orientation, and 'Classes and Objects' 14:15
Can we add a "See Also" section to the bottom of these pages so they can reference each other?
One might think perfect organization would negate the need for "see also", but if you type "object orient...", you'll find yourself on one page, and typing "OOP" will land you on another. 14:17

moritz I made about $870 off the first book before going to Apress, and about $400 selling the second one 17:04
and both didn't even have a proper launch at that time (so they were never advertised as "finished" and on sale at the same time)

moritz so I think with a proper launch, it's not unreasonable to expect to make betwee 2k und 3k USD per book (at least the beginner books; I expect the more advanced ones to sell less) 17:06

tyil is there some matrix showing all elements of unicode and a bunch of popular languages, where you can easily look up which langs support which parts of the unicode spec? 19:00
(and if there isn't, would it be an idea to make one to showcase perl 6's support for it?) 19:01
leont I remember Tom Christiansen doing a presentation on this a few years ago (comparing perl5 to other languages), focussing on regexes in articular. Haven't seen such a thing in perl6 context. 19:02

Aaronepower Is there any shorter way of saying `if $<match>.Bool { $result = 1 }`? 20:54
[Coke] ?$<match>
? 20:55
Aaronepower [Coke]: Where do I put `$result = 1`?
[Coke] $result = 1 if ?$<match>;
skids if you don't care if result gets set to 0, $result = +?$<match> 20:56
Aaronepower [Coke]: That works for me. thanks!
skids: I'm doing something more complex than setting something to zero or one. So I couldn't golf it that far. What does the + do in that context? 20:58
skids converts the Bool to an Int
Aaronepower [Coke]: Can you add an else to an inline if? 21:02
timotimo you can also $result ||= +?$<match>
Aaronepower timotimo: What's `||=`?
BooK where do you people find all the time?
timotimo well, it'll only set $result to 1 if it was falsy before
it's the same as writing $result = $result || +?$<match>

Aaronepower timotimo: My code is `make (join ' ', $/.list) ~~ S/'(' .* ')'//` which gives me the same `Cannot assign to read-only value` and says `Smartmatch with S/// is not useful` 21:34
21:35 _28_ria joined
BenGoldberg In perl5, the way to make s/// (or tr///) generate a new value is by passing a /r flag at the end. 21:35
BenGoldberg wonders whether it would be useful to have s:r/// do the same ;) 21:36
21:37 _28_ria left 21:38 Rawriful left
geekosaur Aaronepower, in perl 5 ~~ temporarily binds something to $_. in perl 6 it is *always* a smartmatch, and it would be smartmatching against the *reslt* of the S/// 21:38
use 'given' instead of ~~
21:38 okl left, BenGoldberg left
skids Aaronepower: S/// works on the topic. Instead S/'(' .* ')'// given $/.list.join(' ') 21:38
Aaronepower geekosaur: The compiler said that too. I just assumed given was part of the error message, not an operator. 21:39

"foo"
skids Maybe try routing around your $/ getting clobbered like that.
Aaronepower skids: I tried `method items($/) { my $a = $/; make S/'(' .* ')'// given $a.list.join(' ') }` no such luck. 22:05
skids You have to do the make on the $a. 22:06
Aaronepower skids: I don't know what you mean by that. 22:07
skids $a.make. not just "make". 22:08
because make works on $/ and after the S/// your $/ is the match from that, not yout current cursor in the grammar.
("method items($a)" might shorten that fist part up.) 22:11
Aaronepower skids: Tried this. same readonly error. paste.rs/zmG
Zoffix Aaronepower: just don't use $/ as the parameter 22:12
skids Try "method items($a)" maybe? Might work, might not. 22:13

Zoffix lizmat: thanks. I'll try to give Think Perl 6 a more thorough read before writing the Green Book (which will likely be a year or more from now). Just flipped through some of it right now and I think I'm aiming for a much more informal and practical approach. Something Average Joe could pick up and get a new skill to do small one-scripts, rather than necessarily "thinking like a computer scientist". Just today 22:51
I was reading about #include's in my C book and I remember how much of a deal the teacher made about them in college, despite them being so trivial to learn. So that's my goal, leave the science well-hidden.
