timotimo Xliff: if you can reproduce it, can you try if the typical MVM_ env vars change anything? 00:18
i may be of more use tomorrow, not any more today :) 00:19
Xliff Fair enough. 00:22
OK. Before you split, what were those vars again?
why not also SPESH_OSR_DISABLE and SPESH_PEA_DISABLE just for fun 00:49
Xliff Thanks! 01:03

xinming SmokeMachine: In postgres, There is something like json_column->>'json_key' = 'value' In this case, What is the right ast to generate the json_column->>'json_key'? NOTE, The 'json_key' can not be placeholder, So, It should be passed as literal string. 01:22
Xliff xinming: What does the model look like. Can you post an example? 01:31
01:33 wildtrees left
xinming Xliff: create table test ( id serial, json_column json ); :-) 01:36
Xliff That's not the Red def though, is it?
xinming I have patched version of Red which generates right sql for json
The default Red def doesn't work with postgres jsonb 01:37
Xliff OK, so you need some way to tell Red to generate the json_column, right?
Do you have a fork I can look at? 01:38
xinming I don't have that.
hmm, I created pull request
Xliff: github.com/FCO/Red/pull/404
Xliff: The json/jsonb one need to be patched.
Xliff: I don't mean to generate the json_column, I need the json op in postgres db. 01:39
Let's json, The result sql will be something like, SELECT ... FROM ... WHERE json_column->>'json_key' = 'value';
Xliff Yeah, that's probably beyond my current understanding of Red... sorry. 01:42
xinming: Yeah, you will have to talk to SmokeMachine about that. 01:51
It looks like that has to be done by .translate 01:52

wtwt5237 could someone please help me with zef? I installed perl6, and cannot find it under /bin? 03:43
sorry if I am missing something obvious.
03:44 hythm joined
rindolf wtwt5237: hi 03:46
wtwt5237: how did you install perl6? 03:47
hythm wtwt5237, I install rakudo with `rakudobrew build moar-blead`, then I nstall zef with 'rakudobrew build zef`, then I find zef in ` /home/hythm/.rakudobrew/versions/moar-blead/install/share/perl6/site/bin/zef ` 03:48
wtwt5237 thanks! 03:49
hythm, let me give that a try. thanks! 03:50
hythm np, I also add rakudobrew bin directory to $PATH as instructed in rakudobrew README.md 03:51
Xliff You can do 'rakudobrew mode shims' and not have to worry about $PATH if you have the environment set correctly. 03:53
hythm good to know 03:58
Xliff :) 04:00
good night! ;)
04:00 Xliff left
hythm gn 04:00
wtwt5237, I think you need to switch to moar-blead `rakudobrew switch moar-blead` before installing zef
wtwt5237 trying these. thanks all! 04:01

SmokeMachine xinming: I think it could be something like: `Red::AST::JsonItemStr.new: .json-column, ast-value “json-key”` 07:09
07:12 stoned75 left
SmokeMachine xinming: but I think it’ll need a specific translation for that ast... that could be something like: `multi method translate(Red::AST::JsonItemStr $_, $context?) { my ($lsql, @l) := do given self.translate: .left, $context { .key, .value }; my ($rsql, @r) := do given self.translate: .right, $context { .key, .value }; “{ $lsql }->>{ $rsql }” => [|@l, |@r] }` 07:19
And the column’s AT-KEY will need to return a rw container... 07:24
And do something like this to be possible to be used on update: github.com/FCO/Red/blob/master/lib...te.pm6#L16 07:26
xinming: ^^
xinming: I think we’ll need to change the update a little... the key expect to be a column name, but should be an AST... 07:29

Juerd Wahnberger: If you use 'tail' instead of 'last', that should work :) 11:36
lizmat also, if you want the last N, you can do .tail(N) 11:37
Wahnberger ahh :) 11:39
11:47 jaldhar_ left 11:48 jaldhar_ joined 11:49 jaldhar_ left
lizmat conversely, if you only want the first, you can do .head 11:50
11:50 jaldhar_ joined
lizmat and .head(N) for the first N 11:50
also, if you want a certain number of elements: 11:51
you can just treat the result of split as an array 11:52
m: dd "123456789".comb[5,0,7]
camelia ("6", "1", "8")
11:53 jaldhar_ left 11:54 jaldhar_ joined
Wahnberger is head inside similar to a perl split like (split(/ bla /))[1] ? 11:54
and tail
slice..in perl 11:55
11:55 jaldhar_ left 11:56 jaldhar_ joined
lizmat head / tail are methods on Seq uences 11:56
many method produce them
$filename.IO.lines is one of them
will give you the first 3 lines of the file indicated by $filename 11:57
Wahnberger i see
lizmat so nothing specific about split
it's just a method that produces a Seq
Wahnberger saved 3 lines of code now :D 11:58

jjatria How can you get a key / value slice from a Hash? I'm thinking of something like `%foo{qw( a b c )}` in Perl 12:25
Altai-man_ can you provide an example of input/output?
jjatria Sure, one second 12:26
Altai-man_ m: my %foo = a => 42, b => 50; say $_ => %foo{$_} given 'a';
camelia a => 42
Altai-man_ or, hmm, do you want slicing?
jjatria Well, I'm after what in Perl is called a slice, but not just for keys _or_ values, but for both 12:27
Altai-man_ m: my %a = a => 32, b => 50; say %a<a b>;
camelia (32 50)
jjatria So, closer to what you posted first
Altai-man_ ah, ok
jnthn m: m: my %a = a => 32, b => 50; say %a<a b>:kv;
camelia (a 32 b 50)
jnthn m: m: my %a = a => 32, b => 50; say %a<a b>:p;
camelia (a => 32 b => 50)
jnthn Depending on whether you want a flat view of Pair objects
*or Pair objects

Wahnberger :) 14:00
..hard to learn and then easy to use..
14:13 jaldhar_ left 14:14 jaldhar_ joined
lizmat Wahnberger: well, once you realize you can use .lines on IO objects as well as strings, as well as on supplies 14:18
and know there is a .words method as well
you should expect to be able to use .words the same way everywhere as well
AlexDaniel uuuuhhhhhhhh 14:20
timotimo heyo AD 14:21
AlexDaniel processing output from tools can be a bit more difficult
abraxxa how can i match any word but not 'custom' in a grammar?
AlexDaniel I don't even remember what's the right way to do it, is it .split(“\n”) ?
timotimo <!before "custom">\w+
AlexDaniel it's definitely not .lines 14:22
abraxxa i've read about lookahead assertion but that doesn't help as I don't want to match something based on what is before or after it
AlexDaniel or is it .lines if you run it on .IO but not strings?
timotimo what you want is to reject matching a thing if it was a thing
which is equivalent to matching something and then refusing the match when at its end there's a thing you don't like in front of the match position
AlexDaniel lizmat: and that's the thing, you can realize it, of course, but it does different things, if I'm not mistaken
abraxxa timotimo: hm...hard to grasp but it seems to work, thanks! 14:23
AlexDaniel like
m: say “foo\rbar”.lines[0]
camelia foo
AlexDaniel I think it doesn't do that on IO stuff, but I'm not sure 14:24
timotimo splitting by /\n/ will do "smart" newline stuff
splitting by /\x[a]/ (or whatever the ascii code for newline is) will only accept the actual \n character 14:25
lizmat right
afaik :-)
AlexDaniel what do you mean right
abraxxa is there a way to define the same regex for multiple different named tokens or rules? 14:26
i've defined a quoted-string token which i use in some other named tokens but don't want it to show up in the match object
as it's just a helper token
lizmat define it as a regex, and use that ?
AlexDaniel m: dd “foo\r\nbar”.split(/\x[A]/) 14:27
camelia ("foo\r\nbar",).Seq
AlexDaniel so clearly that didn't split by \n
timotimo, lizmat: this is something we actually have to fix in the language, somehow 14:29
timotimo \r\n is not \n
just like ä isn't a
blame the unicode consortium
14:29 jaldhar_ left
timotimo all we can do is document better or unconfuse in some other way 14:30
14:30 jaldhar_ joined
AlexDaniel what does unicode consortium has to do with processing output from qqx 14:32
we have to actually make it possible, not document the excuses
maybe it's already possible, I don't remember 14:33
14:35 jaldhar_ left 14:36 jaldhar_ joined
lizmat it's the unicode consortium, afaik, who decided that \r\n is a single codepoint 14:37
14:37 abraxxa left
lizmat different from \r and \n 14:37
AlexDaniel lizmat: it has nothing to do with how you process output from unix commands 14:38
14:38 daxim left
AlexDaniel in which case the output is separated with \n, that's it 14:38
[Coke] wonders why "it's definitely not lines" 14:41
AlexDaniel [Coke]: well, it depends. What are you processing? Is it purely text, or some \n-separated output? The latter is very common 14:42
[Coke]: looking at docs.raku.org/type/Proc::Async
“whenever $proc.stdout.lines { # split input on \r\n, \n, and \r”
El_Che lo
AlexDaniel pretty sure I wrote that comment
because it drives me crazy :) 14:43
14:43 daxim joined, jaldhar_ left 14:44 jaldhar_ joined
AlexDaniel actually, makes me wonder if that's what it actually does 14:44
maybe the comment is wrong 14:45
no, the comment is right :) 14:47
jnthn Probably Blob wants to have a `.split`
[Coke] even though .lines splits on more than just \n, if you're not expecting random \r characters, why not use it?
timotimo \r\n being a grapheme gives a little bit of friction with old-timey tools
14:47 jaldhar_ left
jnthn I suspect for every time there are \r's that are undesirably eaten by .lines, there's thousands more times where the result of using .lines is that one's code is portable if run on Windows. 14:48
14:48 jaldhar_ joined
[Coke] jnthn++, right. 14:48
timotimo don't forget you can use :v to get the thing back that was split on
AlexDaniel … absolutely wrong
timotimo with split, but not with lines
if you .lines on an IO with :!chomp, do the line endings stay with the line strings? i would expect them to.
jnthn Probably, yes. 14:49
AlexDaniel you guys go try to process output of something, then struggle once you get \r, then say this nonsense
timotimo unix tools don't output text, they output "text" :P 14:50
AlexDaniel when you're processing output of some tool, you're typically expecting the line to be in some format
once you get \r in there, it splits the line in half
timotimo i wonder if changing the .in-nl on Proc::Async's pipes by default is more wtf than dwim 14:51
and maybe \r\n and \n is a saner selection than \r \r\n and \n 14:52
AlexDaniel it's not…
14:52 abraxxa joined
AlexDaniel but we should only have two sets of options, that's right 14:52
jnthn No, the sane thing to do is to work at byte level if you're actually processing output that should be treated as an octet stream
And we should make that easier 14:53
14:53 abraxxa left
timotimo unix: text is the ultimate exchange format 14:53
unicode consortium: hold my beer
jnthn :)
timotimo but yes, 100% on Blob.split

timotimo once hashes that don't escape are translated to sets of registers, creating hashes and not using them will be ridiculously fast, and this benchmark if used exactly as shown will become very misleading 16:52

timotimo can you check if setting MVM_SPESH_NODELAY makes the problem appear much quicker? 19:19
Xliff Setting MVM_SPESH_NODELAY also eliminates the issue 19:22
timotimo hm. interesting 19:26

timotimo do we have something nice for "give me an array shallow-cloned from this other array, except index X should have object A in it? 19:35
javascript has the wordy-but-working Object.assign({}, [...arr], {[X]: A}) 19:36
i'd like something that can also work with something immutable

Kaiepi something like this timotimo ?
19:55 daxim joined
wildtrees what does that : | notation do? 19:55
19:57 patrickb joined, jaldhar_ left
Kaiepi | makes a Slip out of the array given, : does a method call in this case 19:58
m: sub clone-with-replacement-at(@arr, Int:D $idx, Mu $obj is raw) { @arr.WHAT.new: |@arr[0..$idx-1].clone, $obj, |@arr[$idx+1..*].clone }; say clone-with-replacement-at((1,2,3,4,5), 2, 42).^name

timotimo i was hoping for something shorter, not longer :D 19:58
Kaiepi hm 19:59
timotimo not that big a deal 20:01
though the javascript version of that code also allows an arbitrary amount of replacements at once
jnthn I'm pretty sure the .clone ain't needed there
If you're slicing then you're already getting a List back 20:02
timotimo right
jnthn Also, 0..^$idx instead of -1, and $idx^..* on the other side :)
Also, no need for .WHAT.new, just .new 20:03
timotimo and probably head($n) and tail(* - $n) maybe
jnthn That's at lesat some saving :)

tellable6 2019-11-07T08:40:24Z #raku-dev <El_Che> patrickb: thank you for your work. I think we are in the same page. I was also thinking on building on CentOS 6
2019-11-07T08:41:45Z #raku-dev <El_Che> patrickb: we need to add macos instructions once we try that out
patrickb El_Che: I hope we'll manage to make the upcoming release the first that also offers precompiled archives. 20:10
El_Che Good plan. I would like to add relocatble .tar.gz to rakudo-pkg, maybe have a look at mac and win as well. Depending on time 20:15
patrickb What's still to be decided is how we promote those precompiled releases on the website. 20:17
El_Che patrickb: I think there is a use case for precompiled packages (certainly if in a repo) and precompiled tar.gz 20:20
patrickb I'd guess we somehow need to put that on rakudo.org/files. Ugh, some more opitions are listed on raku.org/downloads (including your rakudo-pkg packages). Those pages really need some tidying and streamlinification.
El_Che yes, they are ajungle
patrickb Step 1. - Find out who is to decide on how the website can change. 20:22
Step 2. - Find someone with a website affinity.
El_Che we're also in a situation where more distributions have rakudo
patrickb I think the raku.org download page needs to go. It should just link to rakudo.org and have a sentence or two about potential alternative implementations. 20:24
El_Che Download should be in one page, in my view yes. And as long there aren't competing compilers, there is no need to complicate things 20:25
20:26 daxim left
patrickb Also when we have multiple compilers it's clearer when the different implementations have their own download page on their own domains. raku.org is not about implementations. 20:27
And then I'd remove the words "official" and "3rd party" from the download page. Just offer downloads and don't classify them. 20:28
20:31 daxim joined
patrickb is the rakudo.org repository seriously placed in the perl6 org?!? github.com/perl6/rakudo.org 20:31
timotimo well, for anything in the rakudo org you need a CLA i believe? 20:33
if you want a commit bit

dumarchie Hi, can anyone tell me how to re-export an enum? 20:41
I would expect it to be a common use case for a role to export an enum and for a class implementing the role to re-export the enum. 20:44
timotimo you'd do it the same way you re-export anything else, i believe 20:45
our TheEnum is export = OtherPackage::TheEnum perhaps? i'ven't done this yet 20:46
AlexDaniel patrickb: regarding step 1, you decide. If you feel that others may object, then you submit it as a PR to the problem-solving repo 20:47
timotimo: you don't need to sign CLA for rakudo.org changes
dumarchie I tried sub EXPORT, the enum symbol is exported but the enumerated values are not. 20:48
timotimo yes because it's in the perl6 org on github :)
AlexDaniel yep
timotimo ah, i see
it's probably not enough to simply "import TheEnum;" in the class body
rba patrickb: I think too we need to make it more simple for the people to fine the releases. 20:49
timotimo actually, i think you can't put an "our" scoped thing into a role?
AlexDaniel timotimo: ah, I misread the conversation, that's exactly what you said :)
AlexDaniel runs away
timotimo no you will stay here and atone for your sins
just one tone will be enough
rba patrickb: And we need to just offer all the options, src, pkgs and star vx. plain rakudo.
patrickb rba: Just what I think.
AlexDaniel screams in F sharp 20:50
rba AlexDaniel: I had to sign a CLA, but I don't have access to rakudo org in github... Hmmm....
patrickb I suspect just flying under the radar and doing the changes to the websites directly will be a lot less hassle than going through problem-solving...
[Coke]: can you confirm that rba signed a CLA? 20:51
rba patrickb: If you like you create a PR and I setup a separate hosting based on the PR, then we can fiddle arround till we feel fine and repleace the prod ones...
El_Che CLA sounds so ORacle :)
patrickb rba: I like that idea 20:52
AlexDaniel patrickb: that's right, and you can always do it later if people start complaining :)
dumarchie "import TheEnum;" in the class body does not work indeed
patrickb I'll try to put something together.
rba: On a different topic. Can you imagine making that MacOS of yours somehow available for testing and release work for raku devs? 20:53
rba patrickb: You mean ssh access? 20:54
patrickb: On the mac?
patrickb ssh would be the obvious choice, yes.
rba: It was you talking about a MacOS mini catching dust, was it? 20:55
rba patrickb: As the idea came up with running Blin on it as well and now ssh access, I have to extend my DMZ first. But yes why not. Just don't use all my bandwith... :-)
El_Che patrickb: travis has mac builds, looking at it for creating pkgs
rba patrickb: Yes. I wanted to have a look at the macmini this weekend. 20:56
patrickb El_Che: That'd be a nice solution.
rba crosses fingers to have time.
AlexDaniel rba: not sure if you've seen my answer: colabti.org/irclogger/irclogger_lo...11-07#l183
ah, a bit earlier even: colabti.org/irclogger/irclogger_lo...11-07#l165 20:57
rba Realised github actions could start own runners, then I started thinking...
patrickb rba: No hurries.
rba AlexDaniel: Need to check, but thought that mac is 64 bit. 20:58
AlexDaniel rba: sure, but it doesn't mean you'll be able to run linux binaries there
rba AlexDaniel: ack 20:59
El_Che rba, AlexDaniel : I can follow the mac, 64-bit, linux statements
