guifa FINALLY. 00:04
.tell sena_kun :-D llunes, 12 de payares de 2019 a les 00:02:36; 2019年11月12日月曜日 0時02分36秒; понеделник, 12 ноември 2019 г., 0:04:02 ч.
tellable6 guifa, I'll pass your message to sena_kun
00:06 wildtrees joined
TreyHarris guifa: not sure what's that about, but since you happened to three languages two in which I read my linguistics degree, and the third which I don't recognize but seems close to Spanish and French (Asturian maybe?), you should know that those three forms are in differing degrees of formality (assuming I'm reading the Asturian-ish thing correctly...) 00:12
the Russian one is semi-formal, while the Japanese one is quite formal; the only way you could get more formal is by dropping the digits and using kanji for numbers (well, short of going to old Japanese dating, and including the era name) 00:14
guifa TreyHarris: this is the data from CLDR pulled into create “full” date/time string. sena_kun was needing the Bulgarian date formatting the other day but I didn’t quite have it ready
TreyHarris ah. Bulgarian? Bizarre, I wonder how it got so much Romance rooted date names? 00:15
I thought Bulgarian was written only in Cyrillic, too 00:16
guifa It’s Asturian - Japanese - Bulgarian 00:17
TreyHarris Oh, right. I should have noticed the "misspellitng" of November, but my eyes glided right over it
The rest is fine for Russian 00:18
00:19 cpan-raku left
guifa The goal here is that programmers can just say “format-time(now)” and it’ll do a localized time format, or format-date-time(now, :length<full>) to get the above. It’ll auto pull from the user’s environment variables (or equivalent) and be nice and pretty 00:20
TreyHarris Hah, three of those languages have regularized systems of correlatives, too--kismet! 00:21
00:21 cpan-raku joined, cpan-raku left, cpan-raku joined
TreyHarris Got it. Were that it was as easy to do counting and numbering i18n as Gregorian dating 00:22
guifa My goal is to make it that easy :-) 00:23
It’s already working for dates, times, numbers, and lists. The numbers even have a regex token you can use to capture local number forms 00:24
TreyHarris I'm fascinated to see how you handle Japanese, where there are 350 counting systems in the government-approved list (although only a couple dozen in the high school list, which is sufficient to not sound dumb) 00:25
I describe it to folks as if you absolutely had to know what animals were in "packs" vs. "rookeries" vs. "schools" vs. "parliaments" vs. "exaltations" and were unable to speak of any animal without knowing this 00:27
guifa CLDR doesn’t have counter words in it. That’d have to be given to the localizer, sadly.
TreyHarris Ah. Then you end up saying "3 pieces of water" and "2 pieces of pants" 00:28
guifa But I’ve mostly ported over Mozilla’s Fluent framework, and there actually are ways to deal with that
TreyHarris The worst is when you need to encode the spoken form as well, since a lot of languages do absolutely crazy things you can hide under the carpet by using standized decimal digits 00:31
Like languages where you count "Seventy-eight, seventy-nine, seventy-ten, seventy-eleven... seventy-ninteen, ninety"
guifa A lot of that is in CLDR actually 00:32
The rule to cover French numbers from 60-79 for instance is <rbnfrule value="60" radix="20">soixante[-→%%et-un→];</rbnfrule> 00:33
I haven’t yet created the parser and generater yet though :-) baby steps 00:34
abraxxa how can I call make on whatever token has matched for such a token? token param { <src> | <dst> | <proto> | <inface> | <outface> | <sport> | <dport> | <dscp> }
TreyHarris wow, yeah... dipping in, that's pretty cray-cray. Like, you actually have the lists of emperors and consuls of Rome so you can express years before the Fall. And the list of popes... I wonder what CLDR does for expressing ecclesiastical time during the schism?
The full database must be huge 00:36
guifa TreyHarris: they actually already have all the Japanese eras in there. priority is given, like Unicode, to systems in current use, and then other systems can get work done. I think the last release added like 3-4 different new calendar types 00:38
st.unicode.org/cldr-apps/v#locales/// take a browse
abraxxa: trying this
TreyHarris guifa:yep, i found it. I was just looking at the proposals for the older systems because that's where it truly gets pretty ridiculous
guifa token param { $<match>=[<src> | <dst> | <proto> | <inface> | <outface> | <sport> | <dport> | <dscp>] } 00:39
I think that’ll work
abraxxa: oops, sorry, I guess it doesn’t. That only works for text capturing =\ 00:43
There may be a cleaner way to do it but probably the easiest is
method param { make ($<src> // $<dst> … ).made } 00:45
But in general you might want to look at using a proto token, which sort of automagically handles it for you
so you’d have
proto token param { … }; token param:sym<src> { … }; where you insert the actual definitino of <src> there. Then you call param.made, it’ll contain whichever of the various tokens it actually matched. Caveat: treats all tokens with | alternation, not ||. 00:47
abraxxa yeah I've looked into that but I also have cases which are more complex like rule group { 'group with' <param>+ [ <router> | <server> | <group> | <comment> | <include> ]+ 'group end' } 00:48
but it starts to work now, thanks! 00:50
guifa FOr that one, I would pull that router/server/group stuff out and put it into its own tokens
One of the things I’ve learned is that the smaller and more numerous your tokens are, the more manageable things tend to be.
abraxxa they are separate tokens 00:52
rules in my case
a group can contain any of them 00:53
guifa I mean make it like
rule group { 'group with' <param>+ <option>+ 'group end' }
proto rule option { * } 00:54
rule option:sym<router> { routerdefintion }
abraxxa got it
will try that after some sleep
thanks for the help and good night! 00:55
guifa sleep well! 00:57

09:07 Altai-man_ joined 09:09 sena_kun left
abraxxa what's the return value of docs.perl6.org/type/Hash#method_push ? 09:18
Altai-man_ a element pushed, no? 09:24
abraxxa Altai-man_: I had to use @options.push($group.push(%params)); instead of @options.append($group.push(%params)); 09:39
how can I grep for defined values?
make $/<option>».made.grep: .defined; 09:40
Cannot use Bool as Matcher with '.grep'. Did you mean to use $_ inside a block?
I already tried five different syntaxes
make $/<option>».made.grep({ .defined }).list; seems to work 09:43
Altai-man_ grep(*.defined)? 09:45
you use whatever star syntax when there is no block, but with a block you get $_ to work with
abraxxa ok, that works too 09:49
I want to return a list instead of an array to that I don't get an array inside another array but instead adding the items of the inner to the outer array, how can i do that?
it's in a grammar action method 09:50
Altai-man_ convert using .List?
abraxxa there seems to be an upper and lowercase list method 09:52
but neither is documented docs.perl6.org/type/Array
Altai-man_ m: [1,2,3].List.say;
camelia (1 2 3)
Altai-man_ m: [1,2,3].list.say;
camelia [1 2 3]
abraxxa uppercase gives me a Cannot call 'push' on an immutable 'List' 09:53
lowercase doesn't change the output
Altai-man_ abraxxa, can you provide a bit more of your code?
abraxxa method TOP ($/) { make $/<option>».made.grep(*.defined).list; }
one if the option types is group
which should add n hashes to the TOP list instead of an array including its contents 09:54
make @options; is how I currently return the generated array in method option:sym<group> ($/) {
Altai-man_ m: grammar G { rule TOP { ('a')+ } }; G.parse('aaa').say; 09:55
camelia 「aaa」

abraxxa not sure if the group can return multiple items instead of one array 10:00
so if the upper layer must handle it be introspecting what the lower one returns

camelia (a a a)
Altai-man_ abraxxa, something like this ^ ?
abraxxa Altai-man_: yes, thats the basic structure only that token a might return a Hash or an Array 10:03
but I guess I have to code that using a given when based on the type 10:04
Altai-man_ you can do `my $opts = $<options>.made; make foo, bar, $opts`
implementation of an action method is not restricted to a single line thing 10:05

abraxxa paste.scsys.co.uk/587140 10:06
patrickb o/ 10:07
Altai-man_ patrickb, o/ 10:08
abraxxa, WHAT is redundant in `given/when`
abraxxa, why do you need `.hash` call in `when Hash`? I think you shouldn't 10:10
abraxxa thanks for the suggestions, both work 10:12
Altai-man_ \o/
I am also a bit confused about what the results of `@options.append($group.map({.push(%params)}))` would be, but maybe that's because I don't know about data structures involved
abraxxa it seems I need the same code in the TOP rule 10:13
TOP method
Altai-man_ result of `.push` is the element pushed, so if you're doing it in map, it is equivalent to just `%params`
abraxxa the TOP method should always return a List or an Array 10:14
Altai-man_: I'm adding all key/value pairs of the %params Hash to each element of the group Array 10:15
@options.push($group.map({.push(%params)}).list); is the same 10:16
Altai-man_ m: my $group = [1,2,3]; $group.map({ .push(%( :a42 )) }).say; 10:19
camelia Cannot resolve caller push(Int:D: Hash:D); none of these signatures match:

Altai-man_ m: my $group = [%(),%(),%()]; $group.map({ .push(%( :a42 )) }).say;
camelia ({a42 => True} {a42 => True} {a42 => True})
abraxxa is there any type besides Array I could use to return from group?
Altai-man_ m: my $group = [%(),%(),%()]; $group.map({ .push(%( a => 42 )) }).say; 10:20
camelia ({a => 42} {a => 42} {a => 42})
abraxxa instead of group introspecting it's contents I like that a group rule just returns multiple hashes instead of an array of hashes
Altai-man_ m: my $group = [%( b => 50 ),%(),%()]; $group.map({ .push(%( a => 42 )) }).say;
camelia ({a => 42, b => 50} {a => 42} {a => 42})
Altai-man_ m: my $group = [%( b => 50 ),%(),%()]; $group.map({ $_.push(%( a => 42 )) }).say; 10:21
camelia ({a => 42, b => 50} {a => 42} {a => 42})
Altai-man_ hmmm...
I'd add $_ for clarify, but not smart enough to think of something more obvious
abraxxa, maybe you can `.flat`? 10:22
ZzZombo m: &i.say
camelia Nil
ZzZombo m: dd &i
camelia Nil
ZzZombo m: dd &i, i
camelia Nil

camelia Sub rand = proto sub rand (*%) {*}
Altai-man_ m: my @a = [%( a => 42 ), [ %( b => 50 ) ]]; for @a.flat -> $h { say $h }
camelia {a => 42}
[b => 50]
Altai-man_ m: my @a = [%( a => 42 ), [ %( b => 50 ) ]]; say @a.flat
camelia ({a => 42} [b => 50])
Altai-man_ m: my @a = [%( a => 42 ), [ %( b => 50 ) ]]; say @a.flat.flat
camelia ({a => 42} [b => 50])
Altai-man_ ok, this is not super flat. :/ 10:23
m: my @a = %( a => 42 ), [ %( b => 50 ) ]; say @a.flat.flat
camelia ({a => 42} [b => 50])
abraxxa works when I add it to TOP but not to the return value of group

tobs without the sigil, I guess one would have to bind a container to the name at initialization 13:41

camelia 10
tobs so you can do without sigils, but I don't know of any syntactic sugar for that (except for the sigil) :)
El_Che I think that sigils + constant cover most bases 13:43
sigilless vars sounds to me more usefor for people creating slangs or DSLs :)
no ":)" intended, sorry :)
tobs or in signatures
El_Che tobs: to accept different type of containerized values? 13:44
jnthn Also in places you really don't want to impose any context
Like when building lazy pipelines out of parts
tobs El_Che: I was more thinking that parameters are ro by default, so it doesn't matter that they're not variable and indeed it sometimes looks nicer without a sigil 13:45
but those are interesting points 13:46

tobs now I wonder if a proper "Raku from ground up" tutorial shouldn't start with sigilless variables and binding, and then introduce the sigilled ones as a convenience thing. 13:51
[Coke] imagines you could teach it either way. 13:55
El_Che I think that one should learn the 80% stuff first and then the special cases 13:57
14:03 mid_laptop left
robertle_ also, the main goal must be to write readable code, right? the sigils give extra, perhaps redundant, information about what that variable is. that helps readability a lot. so there must be a good reason to avoid that, and "looks nice" doesn't sound like a very strong reason, eye of the beholder and all 14:03
the argument earlier that you may sometimes want to deliberately make the point, or abuse the system for DSL reasons. that's a bit different... 14:04
14:11 lucasb joined
mspo is sigilless the preferred idiom? 14:16
[Coke] mspo: depends on what you're trying to do. 14:24
for beginners, I'd argue the default should be with sigils.
mspo what will rakucritic say by default 14:26
[Coke]: I love sigils, personally
[Coke]: I know a lot of people don't but it's, like, free information 14:27
sort(foo) vs sort(@foo)
14:27 thundergnat98 joined
mspo [Coke]: I like to pack in contextual information where it's easy 14:28
server hostnames are another good example
thundergnat98 FWIW, sigiless variables variables are in general faster when declaring in a tight hot loop. They seem to have less overhead tan sigiled variables. 14:29
Probably just an artifact of our current optimizations and not long term... but I'm writing programs in the now. 14:30
See rosettacode.org/wiki/Palindromic_ga...ers#Perl_6 Using sigiled vars in the iterators imposed a small but consistent performance penalty. 14:31
mspo that sounds like a bug to me 14:32
thundergnat98 Like
mspo I guess the sigil forces a type check on each iteration
thundergnat98 I said, an artifact of the current state of the optimizations.
jnthn Remember that `my $foo = 42` means we allocate a Scalar, and `my \foo = 42` does not 14:33
So you're saving on allocations, GC, and dereferences
robertle_ but would a future version of the runtime not optimize that away? 14:35
14:36 thundergnat98 left
mspo what does \foo = 42 allocate? 14:37
14:40 kensanata joined
mspo oh you couldn't use \foo in a loop since you can't change its value (thinking, like, a for loop) 14:43
they're like erlang atoms
a helpful comparison for almost no one ;)

thats the use case i was considering 14:55
14:56 xinming joined 14:57 thundergnat23 joined
mspo thundergnat23: I don't actually get why that's allowed 14:59
thundergnat23 tbrowder: yes. And if your class has a STORE method, you pretty much have to. See Rakudo issue #3292
Mspo: think of it as a temporary constant.

robertle_ cool, but then "it's currently a tiny bit faster" doesn't side like a good basis for general code style recommendations (as usual) 15:08
15:09 Altai-man_ left
mspo tyil: lol 15:13
lucasb it's not just a performance matter. using a sigilless "variable" also shows the intention of, well, the intended use :)
mspo would $* do the same speed up? 15:15
I probably (definitely) don't grok the lambda -> scoping to get it
robertle_ lucasb: sure, if the sigilles variant makes it more clear then of course it's the better option. I would bet however that 90+% of all code does not fall into that category...
guifa has a code block he’s using for the advent post that I think is a good use of sigil-less vars 15:19
but it’s basically a pure functional math expression 15:20
robertle_ nice teaser ;) 15:23
guifa Let’s just say I’ve never seen a cleaner block to calculate Q-grams before 15:26
(five lines. FIVE LINES. and no nasty golfing line noise to do it) 15:27

AlexDaniel also, when I'm busy, I'm actually writing a bunch of raku code 19:17
which at some point used to be very useful because I'd stumble upon bugs all the time
nowadays I see no bugs

abraxxa can a make return multiple things? hashes in my case 20:08
in Perl 5 in a map block you can return no list items by returning () or more than one, is this possible here in an action class of a grammar too? 20:10
20:14 ufobat_ joined
tobs m: my @a = map { $_ %% 2 ?? slip([$_, $_]) !! Empty }, 1..10; dd @a 20:16
camelia Array @a = [2, 2, 4, 4, 6, 6, 8, 8, 10, 10]
tobs abraxxa: using slip() you can return a multitude of elements which flatten into a list (@a in that case). Empty is a Slip of the empty list, so it effectively returns nothing from a map. 20:18

abraxxa tobs: PERFECT! thanks! 20:19

tbrowder hi, question on private methods, can i have a public and a private method with the same name, but distinguished by the ! 21:29
lucasb m: say class { method foo { 2 * self!foo }; method !foo { 21 } }.foo 21:33
camelia 42
tbrowder lucasb: thnx! i forget about using the repl here 21:35
lucasb m: class { method bar { "[$.foo]" }; method foo { 'x' } }.bar.say 21:38
camelia [x]
21:38 patrickb left
lucasb m: class { method bar { "[$!foo]" }; method !foo { 'x' } }.bar.say 21:38
camelia 5===SORRY!5=== Error while compiling <tmp>
Attribute $!foo not declared in class <anon|1>

horizontal whitespace
lucasb awww :(
it would be orthogonal if $!foo worked for private methods, like $.foo works for public ones :) 21:39

tellable6 2019-11-12T15:00:28Z #raku <mspo> thundergnat23: can you skip assigning a name at all in that case?
thundergnat tbrowder: What's up? 21:59
tbrowder i have an avl implementation for throwing darts at
TreyHarris simulated dart-throwing? Neat! 22:00
thundergnat Cool. Want observations?
tbrowder yes, i’ll put it in a gist shortly... 22:01
see gist gist.github.com/tbrowder/c18009374...599588eec9 22:07
i still need a delete method, and i would like to wrap more stuff inside the tree so one doesn't have to have the node outside the tree object. 22:09
line 62 is missing a semi on the end 22:13
thundergnat Extra closing parenthesis and missing semi 22:14
Looks ok to me so far. At least, I see nothing that makes me say hmmm. 22:17
