guifa2 What are some built-in routines that use +@foo slurpies in their signatures 00:30
notagoodidea sortiz: thanks!
sortiz guifa2: +@foo is like **@foo, to avoid flattening iterables. 00:39
m: sub foo(*@a) { dd @a }, foo 1..3, 4..8;
camelia Array element = [1, 2, 3, 4, 5, 6, 7, 8]
sortiz m: sub bar(+@a) { dd @a }, bar 1..3, 4..8;
camelia Array element = [1..3, 4..8]
sortiz Used by built-ins when we want to preserve the structure of its inputs 00:42
00:49 notagoodidea left
guifa2 sortiz: I know what +@foo does, but I was trying to come up with some examples of builtins in that use it 01:06
all I can think of is for, but that's technically a control structure, not a routine
01:17 Celelibi joined 01:21 xinming_ joined
sortiz guifa2. Sorry, misunderstood your question. In core, I found the built-ins 'cache' and 'reverse' as examples. 01:23

elcaro guifa2: I was looking for an old blog post the other day, as just happened to skim past an old p6weekly post mentioning the `+` sig with regards to the one-arg rule 02:38
p6weekly.wordpress.com/2015/09/28/...-birthday/
maybe it's interesting for you
guifa2 elcaro: yeah, I knew the history and all, just looking for some nice examples in the wild — the talk I'm doing starts with surprisingly intuitive stuff, and then transitions to how module devs can leverage them to make things Just Work™ for users 02:40
I could think of pretty good examples for everything else
I still prefer my alcoholic description of the slurpies 02:41

02:47 lucasb left
elcaro Nice... I'm in a conference call right now (supposed to be working, i guess) so i'll have a better read later 02:48
probably outside of the scope of your blog post, but regarding the first/rest thing, there's also unpacking sigs 02:51
ie. `foo(*@all ($first, *@rest))`, or just `foo(*@ ($first, *@rest))` if you don't care about all
guifa2 Yeah, blog post is a year+ old now (it still calls it Perl 6 ha) 03:02
Do you know any modules offhand other than Cro that take advantage of foo { … } , where foo is actually a sub that functionally appears to be a control structure? 03:03
elcaro lizmat's `silently` comes to mind 03:05
guifa2 oh perfect! 03:07
That's actually a brilliant example. it's almost the same as quietly (which is a control structure) 03:09
elcaro yeh, that's why I thought of it. 03:15
(that, and I used it recently, so it was fresh in my brain)
03:15 brtastic joined
guifa2 I'm trying to avoid slang-y stuff, and show just how much vanilla Raku can do 03:19
But I think I feel comfortable enough with slangs I can write an article on creating one's own quoting structure, which I think would be super useful for some modules 03:20
tony-o slangs are rad 03:29
haskell slang brings all of hackage to raku 03:30
03:41 sortiz left
guifa2 tony-o I was a bit overjoyed once I got a term slang working. Even with just using the basic QAST op 'call', you can do so much. Once RakuAST is around … mmmm 03:44
tony-o is rakuast going to speed things up or is it just going to make doing something like code coverage easier/nicer? 03:47
i think two PTSes ago i did some hacky nqp thing where i was able to insert `got here` messages to figure out code coverage 03:48
guifa2 It's main purpose isn't speed, but my impression is that it can help workout certain optimizations better and result in it eventually. 03:49
IIRC from what lizmat was saying, one of the major reasons we ended up with it is jnhtn didn't like the idea of using EVAL for constructing code blocks ha 03:50
But the long-running desire for macros no doubt helped out too
tony-o macro yo macros 04:09
sounds like it's going to be nice 04:11
guifa2 In my case, it's going to be awesome, because I've struggled to be able to adequately mimick regexen. I can do everything *but* interact with the other languages (Q, Regex, and, I dunno, what do we call Raku that's neither Q nor Regex?) 04:13

notandinus i have a list like this: <a b c d>, <e f g h*> 05:37
^ i want to remove * from h and note down it's co-ordinates 05:38
removing * is easy with deepmap, how can i note down it's co ordinates?
m: (<a h*>, <b c>).deepmap(*.comb[0]) 05:39
camelia ( no output )
notandinus m: say (<a h*>, <b c>).deepmap(*.comb[0])
camelia ((a h) (b c))
05:46 rindolf joined
elcaro notandinus: do you just need it to work on a list-of-lists? or does it need to work with arbitrary nesting of lists 05:50
notandinus it's just list of lists, and 4x4 to be exact 05:53
i could do a nested for loop but i was wondering if there is a general solution
elcaro: ^
moon-child hmm, I have an apl solution but it doesn't translate to raku. (Missed opportunity, maybe :) 05:57
(there's a builtin that tells you the coordinates of 'true's in a multidim array) 05:58
elcaro nothing comes to mind. i would probably do a nested map with indices 06:00
m: my @a = <a b c d>, <e f g h*>; say (^4 X ^2).grep(-> ($y, $x) { @a[$x;$y].contains('*') })
camelia ((3 1))
elcaro need a `deepgrep` that you can use the `:k` adverb with :D 06:01
notandinus i see 06:02
elcaro moon-child: i've been dipping my toes into APL recently. makes me wish for an `Inline::APL`
or a slang (similar to Slang::SQL) that you can just evaluate APL expressions in Raku code 06:03
moon-child that would be cool 06:04
a good start would just be implementing all the primitives as raku functions. Hyperoperators are neat, but nothing like a real rank operator
elcaro I have a been mucking around with doing basic APL stuff with Raku 06:10
just converting exampls from the learn dyalog book
gist.github.com/0racle/b2b2514f8b9...fe1b333b17
very basic
but would be interesting to implement APL in Raku... although I suspect it could benefit from more speed/development on Native Array 06:11
that gist is just a few sample pieces of code from the start of the Mastering Dyalog APL pdf 06:13
06:21 jmerelo joined
notandinus i have this array @visited and @puzzle 06:29
@puzzle = <a b>, <c d>; @visited = (True, False), ((Any), False) 06:30
i want to print @puzzle but replace characters that have already been visited with * 06:31
i could just use nested for, is there another way of doing this? 06:32
i guess not because we need the indexes, right?
06:35 wamba joined
elcaro yeah, you need to do like a deep zip. maybe you need to create a helper function that returns nested indices and implement functions you need around that 06:40
tbh, I haven't put a lot of thought into a better solution, so maybe someone else might come up with a more concise way. 06:41
06:45 jmcgnh left 06:51 jmcgnh joined
elcaro notandinus: not the most elegant solution, but probably how I would handle it in a pinch: gist.github.com/0racle/72afb15114b...e8a7b8e121 07:04

Scimon I got a new laptop and it took me a while to get IRC setup. 09:46
timotimo irc drivers notoriously difficult to get working right, especially on new hardware 09:47

Scimon Mostly I just didn't think about it. 2020 you know, hard to get the brain in gear. 09:47
moon-child timotimo: I hear the windows builtin ones work pretty well ootb 09:48
Scimon I'm trying to get myself in a better place this year.
As such I'm picking up a half finished module I was working on which led me to think of a question. I see there's work being done on fez do we have a preference for module upload location? 09:49
timotimo there's this incredible hack called "IRCDISWrapper" that runs ms comic chat in wine and autmates the UI to expose a line-based API
Scimon I'd need to run windows first ;) 09:50
Oh wait. Wine... Mmmmm
But yeah. Are we moving away from CPAN? 09:55

PimDaniel hi, c'est encore moi. 11:40
\o
Is there a solution do declare an array of Int tuples? 11:41
Or should we control it aftewards?
lizmat my Int @a ? 11:43
are the tuples of the same number of elements ?
PimDaniel Hi lizmat: i just need ((Int,Int),(Int,Int),(Int,Int),(Int,Int),...) 11:44
Each tuple is a coord (x,y) point.
And they should be minimum 4. 11:45
but can be more.
But from the start, we do not know the coords so this is probably not possible. 11:46
Scimon When not make a Point class?
PimDaniel hum
lizmat class Point { has Int $.x, has Int $.y } 11:47
PimDaniel why not : yes!
Scimon That should have been a why not when
timotimo use complex numbers and make a mathematician angry
PimDaniel Suis Null en math :(! 11:48
yes with a Class we can make any control we want!, i'll try this. 11:49
Thank's for the idea.
lizmat m: class Point { has Int $.x, has Int $.y }; dd Point.new(x => 42, y => 666)
camelia Point.new(x => 42, y => 666)
PimDaniel Yes : we can see this in any school case curses or example. 11:50
lizmat note that classes with accessors optimize better than arrays and indices
PimDaniel Heu not shure to understand : there's allready a Point class? 11:51
no no no. 11:52
lizmat no, but it is frequently used in examples :-)
PimDaniel Yes : easy to make it.
thank's a lot : i must go now, back later... 11:53

lizmat Scimon++ 12:03
Scimon I'd also love to be able to write (3,4).Point() but I guess that's a way off. 12:04
lizmat I think you can? but vrurg_ would be able to quicly say how
Scimon Not directly you get a "No such method Point" error ATM. 12:05
elcaro wouldn't that have to try calling .Point() on a list first before realising it's an unknown method, then check if a Point.COERCE is available in the callers namespace
12:06 MasterDuke joined
Scimon I would guess so yes. 12:06
12:07 aborazmeh left
elcaro seems it would be _possible_ but maybe not worth the added ambiguity 12:08
[Coke] guesses he should not be surprised at all the APL love that pops up in here from time to time 12:33
[Coke] did a POC for APL on parrot years like 12 years ago.
[Coke] tries to figure out what github.com/coke/paraplegic/blob/master/t/jaah.t is doing. 12:34
lizmat feels like a rot13 ? 12:35
MasterDuke just heard [Coke] announce Slang::APL, wonder what the release date is...
notandinus is there something like fatpack for raku? 12:36
lizmat not to my knowledge
[Coke] lizmat: ah, it's removing all the FX characters, reversing, and also splitting the string in the middle and putting it back together.
12:37 stoned75 joined
[Coke] ... wow. so old I apparently wasn't doing a LICENSE every time. 12:38
MasterDuke: :P 12:39
[Coke] briefly looks at the source, and wonders how this worked. I see ⌽ in the grammar, but not how it's actually doing anything in the actions. 12:45
MasterDuke github.com/coke/paraplegic/blob/ma...pm#L57-L67 ? 12:47
elcaro [Coke]: seems the love flows both ways. came across an article on the aplwiki that has a Raku script for maintaining xkb settings 12:48
aplwiki.com/wiki/Typing_glyphs_on_Linux
(or was it you that wrote it? :D)
notandinus ok so i wrote a script with some modules, how do i turn it into zef installable thing that can also be uploaded to cpan or fez (later) ? 12:56
github.com/andinus/octans
^ it's this, do i just have to add META6.json thing?
also, any comments on the structure or anything related to the project? 12:57
wait, does github not syntax highlight .rakumod ?
jmerelo notandinus: not really. It's probably not caught up with those extensions yet. We did the PR IIRC, but it's not been deployed. 12:58
notandinus syntax highlighted code: git.tilde.institute/andinus/octans 12:59
jmerelo: ah i see
notagoodidea notandinus: normally with the raku shebang, github will highlight the code.
notandinus oh do you also put shebang on modules?
notagoodidea not sure if it changes anything? But if it is just to provide hl on github, it may not be worth it knowing that hl will arrive one day or the other? 13:01
jmerelo notandinus: not really. github uses several heuristics to know how to highlight and find out which language it is. One of them is the shebang line.
[Coke] jmerelo: hello
notandinus i see, thanks. i guess i'll wait for hl, i don't use it for viewing anyways 13:03
any comment on the module thing?
i've read this docs.raku.org/language/modules#Dis...ng_modules 13:04
i was wondering if i should place my modules under Octans:: directory (?) 13:05
notagoodidea I am still looking to the same thing but most the modules I see organize themself around bin/ lib/ where bin/ hold the cli part and lib/ have the lib/Foo/Bar.rakumod for Foo::Bar name. Not sure if it is the favored methods. like App::Octans => lib/App/Octans.rakumod. 13:08
But it is mainly from observation on how package are structured in the raku module space and it depends on the authors but the main ones seems to go around a similar structure (due to the Foo::Bar naming scheme?)
13:09 JRaspass joined
notandinus i see, so i'll place octans.raku -> bin/octans and all other moduels in lib/Octans/ 13:10
notagoodidea it seems like the most common structure I have seen but newbie and so.
notandinus i see, it's fine the structure can be changed anytime 13:11

[Coke] (APL) ah, all the magic is in tools/, weird. :) 13:16

notandinus hmm fez install fails with: (tried git and tar), please ensure one is in your path 13:27
i have both git and tar in $PATH
notagoodidea notandinus: I discovered App::Mi6 (modules.raku.org/dist/App::Mi6) 13:56
Scimon It's v. good. 13:57
notandinus notagoodidea: i see, i'm looking at that and another authoring tool 13:58
i'm still finalising the repository before uploading
notagoodidea not sure how to play with fez as it seems to release to CPAN. 14:01
notandinus: Your feedback about those interests me! 14:02
Scimon Mi6 release to Cpan. fez releases to the new under development Raku ecosystem. As I understand it. 14:06
14:07 aborazmeh left
notandinus notagoodidea: i think fez is not ready yet, it'll be the new raku ecosystem 14:10
after fez is done, p6c will be phased out 14:11
i'm going to upload my project to cpan for now

notagoodidea ok, my C game is quite low but `typedef struct Foobar *Barfoo;` is a way to make the pointer opaque. using NativeCall, `class Barfoo is repr("Cpointer") {}` is the goodway to create the binding? 14:32

notandinus hmm very weird, %?RESOURCES is set to Nil even when i include the files in META6.json 14:49
MasterDuke notandinus: running locally (i.e., from the top-level module directory)? might need a `-I .` 14:51
notandinus MasterDuke: i installed it with zef
i'm trying to access it from bin/octans
hmm it does print something when i try to acess it from a module inlib/ 14:52
am i not supposed to access it from bin/ ?
hmm, it's working correctly when i acess it from lib/ 14:54
but i need to use it in bin/, the main program
MasterDuke not sure then, i've never created a module with a bin/ 14:55
notagoodidea zef seems to install the bin/ in $HOME/.raku/bin
notandinus it's a program, am i doing it wrong? i've put the modules in lib/Octans/* and the program octans in bin/octans 14:56
in my case zef put it here: /home/andinus/star/share/perl6/site/bin/octans 14:57
looking at github.com/tony-o/raku-fez 15:00
dakkar is that your program, or a launcher script? (a call to `CompUnit::RepositoryRegistry.run-script`)? 15:01
15:01 MasterDuke left
notandinus they've put everything in Fez::CLI and just write `use Fez::CLI' in bin/fez 15:01
dakkar: it's my program
i've put the sub MAIN in bin/octans
and i need %?RESOURCES in sub MAIN
dakkar ok, if you run it directly, rakudo can't know what distribution it belongs to, so $?RESOURCES can't work 15:02
zef should have written another `octans` script, probably in star/bin/
15:02 Sgeo joined
dakkar (it'd be in ~/.raku/bin/ for me, but I'm not using star) 15:02
15:04 daxim joined
dakkar actually… I have ~/.raku/bin/zef, and the program itself is in ~/.raku/resources/D5A6DAB7FF5EFBDDBE82A4D69694601F07F66C52 15:04
vrurg Actually, I might be mistaken, but a script can't know where to take resources from. It's a privilege of a module.
notandinus dakkar: i ran find .| ag octans in ~/star and it only has it in ./share/perl6/site/bin/octans
dakkar vrurg: that's also possible, but if so, the documentation needs patching
hmm, I could test it
notandinus i see, so should i turn it in a module and call `use Octans::CLI' like fez is doing? 15:05
vrurg notagoodidea: It's always a good idea
vrurg minimizes script size whenever possible.
It's also a matter of well-organized code. 15:06
notandinus ok i just had to move the whole script to Octans::CLI and add `use Octans::CLI' in bin/octans, it works fine now 15:10
thanks
dakkar yep, just confirmed 15:12
so either docs.raku.org/language/variables#%?RESOURCES or the implementation, is wrong 15:13
15:13 MasterDuke joined
notandinus i see, are you filing a report? 15:14
dakkar yeah 15:15
against rakudo, because I'd like it to work as the documentation says ☺
notandinus it does say "Distribution of the current compilation unit", only modules are part of the compunit right?
dakkar no
programs are compiled
notandinus oh i see,
dakkar `CompUnit::RepositoryRegistry.run-script` exists, so scripts are in the repository of compilation units… 15:16
which strongly implies they are compilation units
notandinus i see
so after this is fixed there would be no need to put programs in lib/X/CLI right?
dakkar the fact they're not (currently) getting *pre* compiled shouldn't matter
it would still be a good idea (for testability, at least) 15:17
notandinus i see, will bin/ things also get precompiled later on?
dakkar that's my understanding
notandinus oh i see, to test the output of the CLI.rakumod thing?
makes sense

dakkar github.com/rakudo/rakudo/issues/4173 15:31
notandinus github.com/tony-o/raku-fez/blob/master/bin/fez is not calling MAIN on Fez::CLI, how does it work then? 15:35
Fez::CLI is defining the MAIN sub but theres nothing that is calling it 15:36
i moved my things in sub MAIN but it doesn't work
MasterDuke the MAINs are exported, so `use`ing it should make them available (and then called) when run from the command line. did you export your sub MAIN? 15:38
notandinus i see, no mine wasn't exported 15:39
thanks, works after exporting
15:40 wamba joined
[Coke] MasterDuke: I figure you were probably kidding... but do we need a slang? or just all the APL operators? 15:46
(I see no modules in the ecosystem for APL yet) 15:47
notagoodidea With NativeCall, is it possible to assign size to Carray as in `struct { int data[3] }` -> `class foo ... { has CArray[int32] $.data }`. Not sure how to give the size of the created array.
15:49 jess left
MasterDuke [Coke]: that was just kidding, i've never used APL so don't really know. but what about Inline::APL? (or all three: Slang::APL, Inline::APL, and all the operators! the more the merrier) 15:50
15:50 clarkema joined
[Coke] inline would be calling out to existing apl; slang would be if there's extra syntax... I think APL::Operators would be fine to start. 15:51
... should be trivial to create an APL::Operators based on the test suite from the old parrot project.
I'll start there.

tony-o notagoodidea: docs.raku.org/language/nativecall#Structs 16:08
doesn't appear you'd need to
unless you're initializing it, then you need to use the CArray[int32].allocate(3) 16:10
notagoodidea tony-o: No I don't initialize it, but I would have to be sure that only 3 elements are provided/initialized on the Raku side of the call before giving it to C. or at least that is how I understand it. 16:12
tony-o ah, try it with that class+TWEAK example in the link ^ 16:13
notagoodidea Yep, seen that, thanks! 16:14
dakkar ooh, wait, an int[3] inside a struct is not a carray, is it?
a carray is a pointer 16:15
that struct contains the three ints, not a pointer to ints
16:15 dataangel left
notagoodidea dakkar: hu? 16:16
16:16 dataangel joined
dakkar AIUI, a CArray is passed to C as a pointer 16:16
notagoodidea So you do : `class .. { has int32 $.data1, etc. }` or `class ... { has Pointer $.data1, etc.}`. 16:18
dakkar but your `struct { int data[3] }` contains the integers directly (you wouldn't malloc that data, would you?)
definitely not pointer
notagoodidea As said early my C game is meh to low, so still learning my pain point when I meet them :) I am all ear. 16:19
dakkar I'm really not the best person for this, as my C is pretty rusty and my understanding of NativeCall is limited
I'd start with `has int32 $.data0; has int32 $.data1; has int32 $.data2` 16:21
at least that should match the memory layout
then you may want to remove the public accessors for those, and provide more sensible ones (and a TWEAK)
tony-o in c that can work both ways 16:27
in this case - int x[3] ==> x[2] is the same as (x+2)
dakkar yes, because foo.data has nominally type int* 16:28
tony-o for NC more just a question of you want to access it
dakkar but that pointer is not stored in memory, it's the compiler cheating
and for NC it matters very much what is actually in memory
if you try to interpret a random int as a pointer, you're going to have a bad day 16:29
16:31 Celelibi left
tony-o yes that's true 16:32
notandinus i uploaded my module to pause under Perl6, how much time does it take to reflect in modules.raku.org ?
[Coke] (APL) so, one operator that won't work: prefix:<|>, which conflicts with flattening. 16:34

PimDaniel I think the documentation is too tricky for newbies. 16:42

dakkar [Coke]: use ❘ instead 😁 16:43
PimDaniel: learning from a reference is, indeed, difficult
PimDaniel If i want to put a sub into a say Misc module out of class : i cannot see a simple example nor explanation to do it a simple way. 16:44
A simple example with an export would help.
dakkar `package Misc { sub foo() is export { return 3 } }`? 16:45
`module Misc { sub foo() is export { return 3 } }`?
sorry

dakkar PimDaniel: was that what you were after? 16:46
PimDaniel Yes thanks : but easy because you know where to search! When i search i found a lot of complicated things that lost me. 16:47
Thank's a lot : but i pass hours searching and finaly forget what i searched!
dakkar yep, docs.raku.org is a reference, meaning it's for people who already know *some* of what they're looking for 16:48
it's not a good resource to learn from scratch
16:48 JRaspass left, stoned75 left
PimDaniel so, is ther a good ressource to learn from scratch? 16:48
i come from Perl5 but not sure it helps. 16:49
16:49 mowcat left
dakkar it helps quite a bit ☺ 16:49
raku.org/resources/ this links to books and things "for newcomers"
[Coke] dakkar: my goal is to use whatever the original APL operators are. 16:50

dakkar [Coke]: ⌶ U+2336 APL FUNCTIONAL SYMBOL I-BEAM maybe? /me is guessing 16:51
PimDaniel I already red a curse for newbie level in French but it's quickly insufisant when you pass the school cases examples. 16:52
dakkar (U+2336 to U+2395 are all APL operators)
16:52 [Sno] joined
dakkar PimDaniel: ah yes, that's the common issue with programming: the tutorials are too simple, the reference is too advanced 16:52
PimDaniel dakkar: thank's for your link! 16:53
perry And to learn how to read reference manuals you need to read reference manuals :P
MasterDuke [Coke]: cool
dakkar in ~60 years, I feel the only solution we've come up with is "keep writing documentation, tutorials, &c &c, eventually something useful will come out"
PimDaniel I need to precise that i'm french too. I can read english and spanish. I understand German a few and no more. But my be a good curse exists in Spanish. 16:55
notagoodidea PimDaniel: Andrew Shitov have a few books on Raku/Perl6 that are nice and a new course coming up at course.raku.org/essentials/

notagoodidea but the Part2/3 are not yet published.

MasterDuke aren't there translations of the docs available somewhere? 16:57
PimDaniel The French one i have IS a translation.
It was very helpfull for starting and i still look at it sometimes. 16:58
notandinus my first raku module: modules.raku.org/dist/octans:cpan:ANDINUS 16:59
notagoodidea notandinus: congrats! 17:01
notandinus thanks :) i had this pause account for so long, i made it while learning perl but never got around uploading any of my perl stuff. 17:03
PimDaniel I used unit module Misc; instead of a block, I tried a multi but it complains about Missing block 17:07
The multis where tested appart and work!

guifa2 Is there any way to specify endianness when working with >8bit blobs? (the read/write functions on 8bit blobs let you specify it, but >8bits don't have it for, e.g., writing out a file) 17:28
tony-o docs.raku.org/routine/encoding#utf...nd_utf16be 17:30
17:30 Celelibi joined
dakkar what's UTF got to do with blobs? 17:31
tony-o that seems to indicate there's a BOM specifier somewhere
dakkar a BOM is a thing in a file 17:32
blobs are in-memory things
guifa2: I get the feeling that blob16 &c are not designed to be serialised
guifa2 Dakkar: yeah, which is kind of a shame, because they do make working with some things easier 17:33
tony-o oop, misread that as buf
dakkar buf are also in-memory things
tony-o i didn't say they weren't 17:34
dakkar guifa2: I think you'll have to write your own read/write subs
tony-o: UTF is for text, blob/buf are a bit more general ☺
guifa2 I think a quick wrapper class will be best 17:35
tony-o i'm aware

PimDaniel is new a particular method? 19:52
or does it behave like any other?
guifa2 sortiz o/
lizmat classes inherit from Any, and "new" is a method provided to each class that way
so it is just like any other method, just provided to you by default 19:53
and like any method, can be overridden if you should decide to want to do that
PimDaniel the best is to tell what i wanna do: 19:54
sortiz guifa2, All Blobs supports reads with the selected endiannes.
Just use one of the Endian enum
The default is NativeEndian 19:55
PimDaniel What does really do bless?
sortiz PimDaniel, bless "creates" the object.
guifa2 PimDaniel: bless actually instantiates the object
PimDaniel and when a class has no new? 19:56
no new method and no bless too?
lizmat it inherits them
m: class Foo { }; dd Foo.new
camelia Foo.new
19:57 Kaeipi left
stoned75 docs.raku.org/language/objects#ind...w_(method) 19:57
PimDaniel how can i call new called with named and positional parameters? Should i make a multi? 19:58
19:59 Kaiepi joined
PimDaniel my $pt = Point.new(x => 39,y => 68); and my $pt = Point.new(39,68); 20:00
guifa2 yeah, just make it a multi
stoned75 at the URL previously mentioned you could read 'If you want a constructor that accepts positional arguments, you must write your own new method'
guifa2 class Point { multi method new ($x, $y) { self.bless: :$x, :$y }; multi method new (:$x is required, :$y is required) { self.bless: :$x, :$y } }; say Point.new(x => 39,y => 68); say Point.new(39,68) 20:01
evalable6 Point.new
Point.new
PimDaniel guifa2: i think it's quite what i was about to write, thank's! 20:03
self.bless(:$x,:$y) instead. 20:04
according to other examples i saw.
20:06 berber44 left
PimDaniel IT WORKS!!!! 20:07
is fact i added multi but i forgotted method multi method , pfff!
it's a sub or a method or something else... 20:08
Is Comma ide efficient? 20:11
lizmat efficient enough that the developers work with it themselves when working for clients ?
*developers of Comma
PimDaniel I just discover that it exists. 20:13
is it written in raku? 20:14
moritz no 20:15
tony-o it's written in uncommon lisp
moritz it's part of the JetBrains IDE framework, which is java, iirc
20:16 domidumont left
lizmat but some parts of it are definitely Raku.... it uses all of the introspection features of Raku, e.g. and you can't do that from Java afaik 20:16
