rypervenche Nice, got my little script working. :) That took a while, but the end result is a lot shorter and cleaner than it was when I started. repl.it/@rypervenche/Dollar-dollar...#main.raku 00:21
Not quite happy with how I have to use those variable names for the decontainerizing, so I'll have to figure out a better way to do that. 00:22
codesections rypervenche: That does look pretty short/clean, thanks for sharing :) Which variable names do you not like? 00:48
rypervenche codesections: The :$key and :$variable that I have to use or the decont doesn't work. I need to go through my history, I think someone gave me another possible way to do it. 00:49
Since my sorting of the baghash creates a sequence of pairs. 00:50
codesections You could just do .key and .value in the body of the for loop 00:52
which doesn't really save anything there, but gets rid of the declaration 00:53

rypervenche Ooh, that's cool. I never knew how $_ worked with multiple variables like that. 02:00
Err no, it's my misinterpretation of it. Still a single item. Got it. 02:01
I think that was my problem. I was seeing it as two things instead of a single pair. 02:02

kensanata I'm looking at my old Perl6+Cro project and can't get stuff install anymore. When I run zef install . I'm getting the error "Could not find Oddmuse::Storage::File::Test in: ... file#/home/alex/src/oddmuse6" which is true, since it's in in the lib/ subdirectory. How do I tell zef that? 10:20
In my Makefile, I have a test target that runs prove6 -l -j=$(jobs) t – what's the equivalent of prove6 these days? 10:21
Yikes, when I use RAKULIB=lib zef install . I'm getting "Cannot look up attributes in a NQPMu type object" ... 10:24
kensanata reads docs.raku.org/language/modules again... 10:26
kensanata replaces all .pm6 extensions with .rakumod, all .t extensions with .rakutest, adds use lib 'lib'; after every use Test; ... 10:33
kensanata runs zef install App::Prove6 ... I'm starting to feel that when I'm done I'm going to write a blog post. 10:34

kensanata I still get that weird error "Cannot look up attributes in a NQPMu type object" which forces me to delete lib/.precomp after some changes to my source files. 11:17
How weird.
And zef still doesn't install the latest Algorithm::Diff. I got my patch into github.com/Takadonet/Algorithm--Diff.git two years ago. What needs to happen for this to be "released"? 11:18
11:18 JJMerelo left
kensanata But other than that: "All tests successful." TEARS OF JOY!! 11:19
Interesting, my make test works, but zef install . still doesn't work: apparently the use lib 'lib' has to come first. Strange that this wasn't necessary for my own testing. 11:26

kensanata Wohoooo
Altai-man kensanata++ 11:46
kensanata, by the way, `use lib 'lib` should not be necessary, no? 11:47
kensanata Altai-man: I'm not sure. I got a ton of errors about modules not being found. 11:49
11:49 dolmen joined
kensanata (Before installation) 11:49
As in: trying to run my tests. 11:50
Altai-man kensanata, can you check if all the files presumably missing are specified in `provides` section of META6.json? 11:51
kensanata At one point that was a problem (they were still listed using .p6 extensions).
Altai-man: I'd be happy to be proven wrong, though. I will zef uninstall the thing and then I'll take a look at github.com/kensanata/oddmuse6/blob...s.rakutest – I'll simply delete line 17, OK? 11:52
Altai-man kensanata, yes. I mean, it will work, but this path is relative and it might go bad if tests are run from other directory (though unlikely). If all files are specified in META6.json, you should be able to safely test things using `zef test` as long as META6.json is correct. 11:54
11:55 ab5tract joined, ab5tract_ joined
kensanata Altai-man: You never run raku t/foo.rakutest? 11:57
Altai-man: This is my first problem: "Error while compiling /home/alex/src/oddmuse6/t/changes.rakutest Could not find Oddmuse::Storage::File::Test" as I'm running raku t/changes.rakutest.
I'm not sure how to run zef test. What do I specify? I usually just use raku t/foo.t, or prove6 t. 11:58
When I run zef test . I also get the same error: "Error while compiling /home/alex/src/oddmuse6/t/changes.rakutest [Oddmuse6] Could not find Oddmuse::Storage::File::Test"
11:59 ab5tract left
kensanata Hm, I guess that module is missing in github.com/kensanata/oddmuse6/blob...META6.json 12:00
How do I specify this Oddmuse::Storage::File::Test module which is not required for installation?
Altai-man kensanata, move this file to e.g. `t/lib` directory and instead of `use lib 'lib'` use, for example, `use lib $*PROGRAM.parent.add("lib");`, which will run file relative to currently executed one. 12:03
See e.g. github.com/Altai-man/cro-ldap/tree/master/t for example
kensanata Altai-man: OK, so I move the file lib/Oddmuse/Storage/File/Test.rakumod to t/lib/Oddmuse/Storage/File/Test.rakumod and changed use lib 'lib' to use lib $*PROGRAM.parent.add("lib"), and now I get a different error: "Error while compiling /home/alex/src/oddmuse6/t/changes.rakutest Could not find Oddmuse::Storage" (which is in lib, not t/lib) and is listed in META6.json. 12:09
Altai-man kensanata, how do you run tests? 12:10
kensanata So I guess I can no longer run tests directly using raku? What about prove6, do you use it? And how can I run zef test such that it only runs this one test?
Altai-man: I use raku t/foo.rakutest, or prove6 t 12:11
And of course zef install does something that I don't understand but also involves running tests.
Altai-man kensanata, are you running executable for prove to work with passing it -Ilib? 12:12
E.g. `prove --jobs=4 -e "perl6-m -Ilib" t/` or something.
kensanata My Makefile has `prove6 -l -j $(jobs) t`
Altai-man Hmm, `-l` should make it work. :S 12:13
kensanata github.com/kensanata/oddmuse6/blob...kefile#L22 for context 12:14
Altai-man: I dunno, it seems to me that I want three ways of running tests: alone, with maximum ouput; in parallel, with summarised output; by zef, because that's what it does.
Altai-man: As it stands, both `raku t/changes.rakutest` and `prove6 -l -j 4 t` complaing about not finding Oddmuse6::Storage; they do list the directories searched. For prove6, file#/home/alex/src/oddmuse6/lib is listed, but /home/alex/src/oddmuse6/t/lib is not. When calling raku directly, file#/home/alex/src/oddmuse6/t/lib is listed but /home/alex/src/oddmuse6/lib is not. 12:17
So... I dunno, looks like there is no way to make it work like you did? 12:18
Altai-man kensanata, I can't reproduce it. 12:19
kensanata, if I run `raku -Ilib t/changes.rakutest` it works for me.
Oh, wait
12:19 patrickb joined
kensanata You add -Ilib 12:19
Altai-man Yes?
kensanata I did not. 12:20
OK, now it works for all three use cases. 12:26
Altai-man kensanata, the thing here is that paths to look up for modules need to be specified somehow. It can be done either using command line with `raku -I$relative-path-to-include` or inside the script or zef does that for you. For your cases, prove and prove6 jsut runsyour specified executable, so it effectively equals to "run raku ..." for each file", thus it needs the -I to work. Single file is the same, needs -I. And zef is smart enough to know what to do. 12:27
Thus you can avoid having `use lib 'lib'` in your code and save some pains.
kensanata I'll just believe you that use lib 'lib' is painful. :) 12:28
Altai-man Might be. :)
kensanata Committed and pushed; thanks, Altai-man 12:31
Altai-man yw
codesections A Hash is mutable (keys can be added/deleted and values can be changed); a Map is immutable. I was thinking Raku had a way to have an Associative with fixed keys but mutable values, but I can't recall what that would be. A Map containing scalars, maybe? 12:32
jnthn codesections: Yes, that should do it 12:39
codesections Thanks! What's the syntax for that? I thought it was the below, but that's not quite working: 12:41
m: my $map := %(a => my $ = 1).Map; $map<a> += 1;
camelia Cannot modify an immutable Int (1)

jnthn m: my %m := Map.new((a => my $, b => my $)); %m<a>++; %m<b>++ xx 2; dd %m 12:44

moritz demostanis: feedback for your website: what the heck is it about? 15:27
it does something automatically with github, but what, and more importantly, why? What problem does it solve? why should I care? 15:28
you should try to answer these questions as concisely as possible at the very top
demostanis As said, reasons *why* you should use it are in the GitHub's README. Should I paste it in the main page of the website? 15:31
"
Many distributions lack some software which can be found on GitHub, most of the time because they are not popular enough. You have the choice to install the binaries at the risk of keeping outdated software on your computer... OR to use HubToDate.
"
moritz demostanis: well, you wanted feedback on the website, that was my feeddback :-) 15:32
demostanis I'll just paste the Github's README... 15:33
tadzik if you advertise a website, it's probably more effective to describe it on the website rather than a github repo's README that people would otherwise have to manually check (after they learn that it exists) :)
demostanis It explains well
15:33 JJMerelo joined

JJMerelo github.com/Raku/doc/issues/3553 codesections
codesections I see. Interesting 15:56
JJMerelo codesections in general, "docs" is what I'm up to (now that the book is finished). So after a few of these, you will see either a push to docs or a StackOverflow question if I can't figure it out...
codesections Cool. Are you doing it with camelia so that others can pitch in? Or do you not have a local REPL available? 15:57
(If the latter, wow – I can't imagine being able to figure things out without a local REPL to interrogate!) 15:58
JJMerelo codesections I'm just lazy and camelia puts the output format we use in the documentation. And, of course, some times someone pitches in and solves the thing. 15:59
codesections No, I have one or may REPLs. It's mostly the "laziness" part of "laziness, hubris and impatience". A bit of impatience, I guess, too. 16:00
16:02 molaf left
codesections Interesting. As it always is to peek into someone else's workflow. Personally, remembering to put in m: and having to copy-paste from IRC would overwhelm any gains from camelia formatting the output. But, like I said, it's interesting to see other workflows :) 16:02

dog_star hey, sorry if this is a silly question but i can't find an answer to it - are multidimensional arrays typed the same way was one-dimensional arrays, eg for a 2 dimensional array whose elements are cells, would it be typed `my Cell @grid`? 16:12

dog_star lucs: not aware of a shirley! i'm phoebe 16:20
lucs 's joke falls flat. Oh well...
JJMerelo lucs er... maybe we're missing all the context 16:21
lucs www.youtube.com/watch?v=B_XuPXGMpLA 16:23
dog_star i'm thinking either the Airplane movies or some pun on 'dog star' that i haven't heard yet :p i have had people ask me 'why so sirius'
lucs The star Sirius is also known as the Dog Star.
dog_star oooh, a combination of both
not enough coffee to get the double-pun this morning 16:24
lucs Sorry :)
dog_star you're good! that's clever
JJMerelo lucs now that's what I call a complicated context.
JJMerelo lols with a slight delay 16:25
dog_star oho i think i know what my problem is, but i am not sure the solution yet
JJMerelo dog_star give it a shoot.
JJMerelo waits patiently to see if this joke works... 16:26
lucs JJMerelo: Um, not sure... :/ 16:27
dog_star m: my Int @a; for ^20 -> $x { for ^5 -> $y { @a[$x;$y] = $x * $y } }
camelia Type check failed in assignment to @a[0]; expected Int but got Array ([])
in block at <tmp> line 1
in block <unit> at <tmp> line 1
JJMerelo lucs a star that shoots...
JJMerelo ducks
dog_star so my guess is that subscript `$x;$y` is not being parsed how i expected, but am not sure how to correct it
JJMerelo dog_star you need to shape it in advance.
dog_star m: my Int @a[20;20]; for ^20 -> $x { for ^5 -> $y { @a[$x;$y] = $x * $y } } 16:28
camelia ( no output )
dog_star huzza
so the autovivification isn't clever enough on multi-dimensional arrays?
JJMerelo dog_star not enough to discover a shape, I'm afraid... After all, @a[$x;$y] has no idea what are the dimensions. 16:30
jnthn A multi-dimensional array is a different thing from an array of arrays; auto-viv will vivify an array, but if the top-level array is typed to contain Int then the assignment won't work out
dog_star that makes sense - i'm coming from an APL/k world, so i am trying to understand the semantics of arrays a bit deeper here
jnthn (A multi-dim array is really allocated as a single blob of memory.) 16:31
dog_star jnthn: ok, that makes sense! in some langs they are equivalent and in some they aren't
JJMerelo: from k i am used to subscripts working like arr[dim1;dim2;dim3...] so maybe i was projecting :) 16:32
JJMerelo dog_star it really makes sense. But I guess that, from the point of view of the implementation, it needs a bit of more work... 16:35
dog_star JJMerelo: oh, i am also the "dog star" on twitter whose thread you are replying to, by the way
yeah, i may add some little PRs for these gotchas, noting them down... 16:36
JJMerelo dog_star love to hear you're fascinated :-) That would be great :-)
codesections dog_star: How do you like Raku's APL-like features? I spent a month or so last year diving into APL, and liked it a lot. But Raku seems to have a lot of what I liked – plus a lot more. But I'd be really interested in thoughts from someone with more experience with those languages
16:37 dakkar left
JJMerelo codesections "plus a lot more" is something we keep hearing about Raku 16:38
dog_star codesections: i'll have to get back to you after i learn a bit more :) have only been looking into it a day or so so far 16:39
codesections JJMerlo: hopefully in a good way? I could see that going either way :D
JJMerelo I followed a doctoral seminar on APL circa 1989. It was a really cool thing. I guess it still is...
dog_star i did give a quick intro talk about apl at a conference: www.youtube.com/watch?v=UltnvW83_CQ 16:40
JJMerelo codesections well, having a lot of stuff in a language is not a bad thing if you live in 2020, I guess. Except if you're talking about frameworks, and the language is Javascript
dog_star++
dog_star JJMerelo: i think it can be either way! i actually like how small APL and k are. but diving into raku is reminding me of a lot of interesting tricks that i haven't seen since i was messing with common lisp and/or haskell, depending on the feature 16:41
i want to make it clear that this is not negative, but raku right now feels most similar to, uh, supercollider... which also had a lot of apl (specifically J) influence! 16:42
codesections Yeah, I agree, at least to a point. Though I think Raku is also, from a certain point of view, a pretty *small* language – it has a lot of orthogonal features (which, yes, can be a lot). But those can be put together in ways that prevent the need for a *ton* of standard library methods that make the effective size of other languages much larger 16:43
dog_star specifically, raku's "whatever" concept is something that i've only ever seen in supercollider before
JJMerelo Now that's a first. Also, supercolliders are *huge*
16:44 TreyHarris left
dog_star JJMerelo: that may be a joke going over my head again, but i mean the audio synthesis language: en.wikipedia.org/wiki/SuperCollider 16:44
16:45 TreyHarris joined
codesections e.g., having first-class Regexs eliminates a huge chunk of `is_ascii`, `is_numeric`, `ends_with`, etc. string processing 16:45
dog_star codesections: in that case, that does sound like a lot of what i like about apl!
JJMerelo I meant the physical supercollider things, the ones used to throw atoms against each other. Now, supercollider was mentioned here recently... Let me check.
dog_star nice talk, I had forgotten all the symbols... 16:48
dog_star it does make me happy that i can still use some of the APL symbols in raku :p 16:49
JJMerelo BTW, there are still some slots open for the 20th anniversary calendar raku-advent.blog 16:50
Pick one of the original Requests for Change, tell us how they eventually ended up in the language, add you rname here github.com/Raku/advent/tree/master/20th 16:51
codesections dog_star: you might be interested keeping an eye on ab5tract's project to add more APL operators to Raku via a module: github.com/ab5tract/raku-SilverAPL 16:52
It's early, but seems pretty cool. (And exposes the metaprogrammabilty that makes me so excited about Raku)
dog_star JJMerelo: ooh, maybe... not sure if i want to pick up a new project right now if it's something else i would need to do ASAP though 16:53
JJMerelo dog_star well, the one for the advent calendar this winter is also open... all of them, too :-)
dog_star JJMerelo: let me look into the winter one, because i am looking for more prompts for projects right now 16:54
JJMerelo dog_star the winter one is totally open, simply some tutorial or article about Raku. Same repo, different file...
codesections I've been meaning to ask, where does Raku's excitement about Christmas come from? (The Advent calendar, the Christmas release, etc)
JJMerelo BTW, the flapper on the doc tests is coming back again travis-ci.org/github/Raku/doc/builds/716978461 It's totally unrelated to anything, and we've had it for a many releases. It's a flapper, and also impossible to golf as far as I can tell. 16:55
codesections Did it start with claims that Perl 6 would be "out by Christmas" (if so, who's claims? Larry?) and just grow from there? 16:56
JJMerelo Maybe jnthn or [Coke] can have a look at it... If it's an error, it must be deep down in MoarVM or whatever.
codesections more complicated, and actually fascinating story. Check out the initial post (by YT) to see how it happened and how Raku became a truly community emergent language 16:57

lizmat received word that Naoum Hankache lives close to the harbour in Beyrouth
codesections Hmm? I know the history of Raku/Perl6 in broad strokes. And have read that post. I was asking more specifically about Christmas 16:58
lizmat his mother and sister have multiple bone fractures but have been released from hospital
lizmat wishes Naoum all the best
moritz tough living over there, I also wish everybody the best 17:03
and thanks lizmat++ for the info
tbrowder codesections: i'm not sure i've heard larry articulate exactly why, i'll give you my take on it: Larry is a Christian and it's obvious in the public life he has lead. as a Christan the Christmas Story and its Advent are central and sacred. the release on Christmas is kind of like a pointer to highlight it, but not in a profane manner. 17:11
tellable6 2020-08-10T19:01:41Z #raku <thundergnat> tbrowder Glad Rosettacode was useful for you. There's a lot of interesting code on there (and some not so good too... ) 17:12
lizmat it was actually cognominal++ who tipped me
codesections d'oh, thanks tbrowder. I'd totally missed the Christmas → Christian connection (which *should* be obvious, but…). I'd picked up on Bless, apocalypse, etc. 17:14
jnthn I think the Christmas joke may have originated around the Pugs time, and was along the lines of 17:15
"every day will be like Christmas when we have Perl 6"

tbrowder can anyone tell me how to get p6doc or rakudoc working again? i think i just read to clone p6doc repo and zef install rakudoc... 17:15

tbrowder jnthn: yes, a Christmas present for sure 17:16

codesections Interesting. I find some of this history really cool. I've been going back and watching some of the old State of the Onion talks that address design goals for perl6/Raku, and it makes for fascinating context 17:17

xinming_ What module is used to traverse tree structure? 19:01
I mean existing module, A bit like Tree::Traverse in perl5, something like that.
codesections xinming: I'm not familiar with anything off the top of my head (which doesn't mean it isn't out there – I haven't explored the module ecosystem in depth yet). Raku is pretty good at traversing trees natively, though. Can you be more specific about what you're trying to do? 19:05
er, xinming_, sorry
xinming_ Ok, my $tree = %(a => [1..10], b => %(sub-tree), c => 'plain-str'); A traverse module will walk through the whole structure and call process sub on array and hash under a tree. :-) 19:07
I can write that, it's just good when we have existing sollution. 19:08
