Kaiepi when i first started using perl6 i thought supplies were just the equivalent of javascript event emitters and would end up something i probably wouldn't need to use 00:52
i was completely wrong and now i use them all the time lol
they definitely help with writing more modular code 00:56
00:56 vrurg joined 00:57 p6bannerbot sets mode: +v vrurg
vrurg If anybody alive here who nows why overriding ACCEPTS for a class doesn't impress the smartmatch operator? It simply ignores the method... 01:02
tobs vrurg: did you override it on what you put on the RHS of the smartmatch? 01:04
vrurg tobs: say, on a Str in $obj ~~ "something"? 01:05
tobs yes, that would call "something".ACCEPTS($obj)
vrurg Augmentation? It doesn't look good... :( 01:06
In your interpretation it even reads oddly: as if a string accepts my object. If it's works this way – I will avoid using this feature. 01:08
mornfall how else would it work? 01:09
tobs m: "operand" ~~ class { method ACCEPTS ($acceptee) { say "do I accept $acceptee ?" } }
camelia do I accept operand ?
vrurg is too used to commong left-to-right evaluation order. 01:12
tobs vrurg: then you can use R~~ instead of ~~ 01:13
vrurg It now makes sense, but is still confusing. I have a context object which keeps track of contexts defined by unique strings. So, $context ~~ "ctx1" | "ctx2" would look great, but I'm not gonna augment junction for this. 01:14
tobs in that case, you might want to use === and the WHICH method 01:16
vrurg tobs: R isn't good too.
tobs: That sounds like the solution! Thanks! 01:17
tobs and write $context === "ctx1" | "ctx2", where === uses the result of $context.WHICH to compare, cf. docs.perl6.org/routine/=== and docs.perl6.org/routine/WHICH
mornfall that sounds super confusing :\ 01:18
=== is supposed to be the finest equality there is 01:19
vrurg And more than that, the context object is a collection of strings (contextes). It can't be uniquely identified with WHICH for that purpose. 01:21
mornfall i'd consider =~=
vrurg mornfall: thanks, I was just about to see if another operator would be helpful. :) 01:22
Kaiepi i also have a programming question if this one has already been answered 01:24
mornfall i think irc can handle some concurrency :p 01:25
Kaiepi alright
i'm writing a chat bot for a website and at the moment it's split into two modules
one for managing the websocket connection, one for handling state 01:26
the one handling state is also handling parsing and commands at the moment, but i want to abstract that out
the issue is i want to abstract it out in such a way that i can paramaterize a role of some sort with any kind of parser to allow for more customization 01:27
since other bots on the site have had the deficit of having very difficult to customize parsing
mornfall parsing isn't super composable by nature 01:28
Kaiepi parsing here can be split into two parts 01:29
one for stuff like battle and chat event messages, and one for chat messages 01:30
mornfall well, the problem is that parsing in the traditional sense is a very top-down matter
maybe you just want to allow competing parses for the same message and sort them out somehow (maybe spit out a score from each sub-parser)? 01:31
Kaiepi the only messages the parsers would be competing each other for are chat messages 01:32
mornfall sure, but parsing commands is easy, even extensibly 01:33
if there is a clear top-down structure, like the first word being a command, then you just dispatch on that 01:34
but if it is supposed to be free-form text, just running all the parsers and letting them tell you how good they think their match is might be the only reasonable option?
anyway, it's bedtime ... gl&hf o/ 01:36
Kaiepi night
thanks for the help
vrurg Kaiepi: the last mornfall suggestion is what I was thinking about: just a parser class used as a kind of filter. 01:37
01:38 yqt left
vrurg Then you could chain them, use parser classes as role parameters – whatever. 01:38
Kaiepi i was thinking a role that manages state that could be parameterized by a command parser and a regular chat message parser 01:40
state obtained from messages received that is 01:42
01:43 random_yanek left
vrurg Kaiepi: class Parser1 { grammar CommandSet1 { ... }; method parse( Str:D ) { ... } }; role StateMgr[ParserClass] { ... }; class Consumer does StateMgr[Parser1] { ... } 01:45
roughly.
Kaiepi looks about right 01:48
i can't use grammars though apart from parsing chat commands because the site's protocol is awful and inconsistent 01:49
vrurg If I understand you correctly, then it doesn't matter. Would it be a grammar or other way of handling the message – the idea is to let a parser class to handle it. I would only define a base role for parsers on top of all this which would demand a minimal set of methods – just to define a standard interface. And then just make things like $parser.accepts( $message ), etc. 01:52
Kaiepi yeah, i understood what you meant 01:53
so you understand what i mean by the protocol being awful it mixes a reasonably well thought out message format with messages that are just text and messages that are raw html 01:58
01:59 random_yanek joined, p6bannerbot sets mode: +v random_yanek
vrurg I hope so. :) The point is to define it your self (or have it defined for you by the client) how that mess is to be dealt with. Without clear definition there will be no good in-code solution. But generally it looks like a work for a filter. 02:00
You pour all the data into it, it lets go useless data bu keeps and gives you back what could be handled. 02:02
I also call it a 'driver architecture' to myself – from the times when drivers were probing available hardware and claiming the devices they could recognize. :) 02:03

jmerelo thanks! Good luck.
mscha jmerelo: it seems more likely that it's doing a string comparison involving (Any). But .max() doesn't give an error...
tyil thanks :>
mscha m: my @foo; @foo[2] = 4; say @foo.max; 12:55

jmerelo mscha: yep, but maxpairs is rather .pairs.max 12:56

pmurias El_Che: that seems like a self-congratulatory Mac users post
I need to make a design choice for rakudo.js, when running with gather/take enabled I need to decide if make function call and decontainerization etc. always return a Promise, *or* make it sometimes return a promise and then deal with with the fact that Perl 6 objects can't expose a 'then' js method
the second option will likely mean that perl 6 methods will likely be prefixed

ufobat_ pmurias, I dont; teaching it to x (==cro) means that you still need to teach x-1 others. I agree that my module is a workaround/hack. But i am not yet willing to give up my search for a simpler interface 15:11
maybe a subclass of IO::Path would do the job better? 15:13
pmurias ufobat_: you mean as a better interface for RESOUCES? 15:14
?

ufobat_ yeah, because there are mainly 2 things i dislike about %*RESOURCES, a) it must be installed otherewise %*RESOURCES is empty, if ia m not mistaken, b) %*RESOURCES does not provide any usefull way to retrive information from it. you need to know exactly what you looking for 15:17

ufobat_ pmurias, i didn't get it, sorry 15:42

but I could just implement the common methods in a IO::Resource class? 15:49

17:15 kurahaupo joined
jmerelo [Coke]: I don't think I can, but let me check... 17:16
17:16 p6bannerbot sets mode: +v kurahaupo
jmerelo [Coke]: What's the problem now? 17:16
[Coke] the site running the doc build needs to have the new version of the module. 17:17
(now that it has the new version of rakudo)
moritz is the new version released? 17:18
jmerelo [Coke]: I'm doing it now
moritz: yes
moritz runs zef upgrade Pod::To::BigPage
jmerelo moritz:
moritz: it's actuall Pod::To::HTML
[Coke] ? 17:19
no it isn't.
moritz The following distributions will be upgraded: Pod::To::HTML:ver<0.4.0>:auth<Perl 6>
[Coke] Pod::To::BigPage is the one that got bumped in the meta6.json
moritz Pod::to::BigPage is at the latest version
in zef
jmerelo [Coke]: and then Pod::To::HTML
[Coke] as long as it gets fixed I won't argue. 17:20
jmerelo [Coke]: I see what you mean. docs.perl6.org/build-log/build-201...+00:00.log
[Coke]: But it didn't fail last time I checked yesterday morning. 17:21
[Coke] once the modules are updated you can trigger a rebuild by github.com/perl6/infrastructure-do...rg-rebuild
jmerelo: it's been failing all along.
every time I've checked the build logs since the site updated rakudo
how were you checkin that it didn't fail? 17:22
jmerelo [Coke]: I checked the update.log at the root of docs.perl6.org. Also, it's generating the perl6.html page correctly: docs.perl6.org/perl6.html#t36.2.5.2
[Coke] docs.perl6.org/build-log/build-201...+00:00.log docs.perl6.org/build-log/build-201...+00:00.log docs.perl6.org/build-log/build-201...+00:00.log , e.g., all failures.
jmerelo: what URL is the update.log at? 17:23
jmerelo [Coke]: right, but there's been a few builds since yesterday and it didn't fail.
[Coke] if there have been builds, where are the logs?
jmerelo [Coke]: it's not copied unless it fails. I checked it while it was being built yesterday morning... That last failing log is from ~ 6 hours before I checked 17:24
[Coke] if they're working, and not getting pushed to the build log dir, that's a different failure mode.
jmerelo [Coke]: logs are only published if they fail.
[Coke] how were they working if they didn't have the updated module, I wonder.
jmerelo: ah. that's a bad design. 17:25
jmerelo [Coke]: well, they're right there for the admin to see, in the logs/build-log directory. 17:26
[Coke]: not my design...
[Coke] never said it was.
jmerelo [Coke]: point is
[Coke] point is, the build system was broken by an untested update (or, worse, an update with a known failure) 17:27
jmerelo [Coke]: Pod::To::BigPage was upgraded yesterday, and that stopped failing.
[Coke]: as always, things were a bit more complicated. 17:28
[Coke]: but everything is pretty much in the issue: github.com/perl6/doc/issues/2424 17:29
[Coke] yes, but from over here, looks like that issue was not part of the discussion about whether or not to roll out the updated rakudo on the build box. 17:30
17:30 graphene left
[Coke] sort of thing that would have been caught by (at one extreme) a more automated deployment process, or, (at the other extreme) a change management discussion before pushing out a potentially breaking change. 17:31
jmerelo [Coke]: we'll, it's also kind of a catch-22 situation. We needed to upgrade _because_ new Pod features had been rolled out and _were_ in the documentation.
17:31 graphene joined
[Coke] but why push a breaking change when another change was needed as a followup? 17:32
from a deployment standpoint, it's more correct to combine those changes and do them simultaneously.
17:32 p6bannerbot sets mode: +v graphene
jmerelo [Coke]: which kinda what was done. 17:32
[Coke] BTW, I'm not trying to blame anyone, just trying to point out how we can do this better going forward.
jmerelo [Coke]: I know, and I appreciate that. 17:33
[Coke] jmerelo: the module's changes weren't even *published* when the rakudo update was done.
jmerelo [Coke]: well, they were... kinda.
[Coke]: as I say, it's complicated.
[Coke]: let's start with a fact that has not been mentioned before: I was away from my desktop, in a sofa, due to back pain and on sedatives. 17:34
[Coke] "it broke". that's not complicated; esp. when it didn't have to.
hope you feel better.
jmerelo Right before that, I had bumped up Pod::To::BigPage so that it was updated, and was about to do it. 17:35
lizmat hugs jmerelo
jmerelo [Coke]: not perfect, still with heat on the zone and painkillers, but at the desktop, now.
lizmat: thanks
[Coke]: anyway, you are right, things shouldn't be done that way, but it was due to unexpected circumstances. 17:36
We were about to upgrade Rakudo and push the new version of Pod::To::BigPage, but then things went loose.
The site was broken for a day, and I kinda tried to fix it yesterday morning (European time), which I think I did. 17:37
[Coke] moritz: if you can get me access to the build box again, I'd appreciate it. Probably just need a password reset for coke 17:38
jmerelo [Coke]: I don't think I have the privs for that. But let me give it a try 17:39
moritz [Coke]: can do

[Coke] is there a zef command to verify that you've got versions of dependencies installed that satisfy meta6.json? 17:58
we probably want to have a t/ test that verifies deps (whether it's a callout to zef or a handrolled one with use/require)
jmerelo [Coke]: zef install --deps-only will install new versions if they are more up-to-date 17:59
[Coke]: but that's right, we should have that.
[Coke]: it probably involves some CompUnit dark magic I don't really know how to do, but yes, we should have it.
[Coke] there was a point when docs upped the req to 0.5.0+ but 0.4.0 was still installed where my zef didn't fail. 18:00

Elronnd I have a c library with a function that has this signature void terminal_print_ext8(int, int, int, int, int, const char*, int*, int*). So I tried to wrap it like this: our sub print_ext(int32, int32, int32, int32, int32, int32, Str, Pointer[int32], Pointer[int32]) is native("BearLibTerminal") is symbol("terminal_print_ext8") { * }. But when I say my $destw = Pointer[int32].new(); my $desth = 19:57
Pointer[int32].new(); print_ext(0, 0, 0, 0, 0, "Bla", $destw, $desth), I get an error of Calling print_ext(Int, Int, Int, Int, Int, Str, NativeCall::Types::Pointer[int32], NativeCall::Types::Pointer[int32]) will never work with declared signature (int32, int32, int32, int32, int32, int32, Str, NativeCall::Types::Pointer[int32] $, NativeCall::Types::Pointer[int32] $). I'm guessing that this is down to a
mismatch between NativeCall::Types::Pointer[int32] $ and NativeCall::Types::Pointer[int32], but what really is the difference there?
And how do I resolve that? 19:58
timotimo i would recommend "int32 $destw is rw, int32 $desth is rw" instead
Elronnd how do I declare the variables of $destw and $desth then? 20:00

I tried my int32 $destw is rw, but got an error. If I just do my int32 $destw, I get the same signature mismatch 20:02
20:03 quester joined, p6bannerbot sets mode: +v quester 20:04 molaf joined 20:05 p6bannerbot sets mode: +v molaf
timotimo that should actually work, though 20:08
but the signature mismatch could be about something else
i mean having "my int32 $destw = 5" and then the "int32 $destw is rw" in the signature 20:09

Xliff Elronnd: Your problem isn't the pointers, it's the naked 0s 20:35
So: our sub print_ext(int32, int32, int32, int32, int32, int32, Str, Pointer[int32], Pointer[int32]) is native("BearLibTerminal") is symbol("terminal_print_ext8") { * }; my int32 ($a, $b, $c, $d, $e, $f) = (0 xx 6); print_ext($a, $b, $c, $d, $e, $f, "Bla", $destw, $desth) 20:37
Leaving $destw and $desth as you had them. 20:38
20:39 wamba left
Xliff Note that » my int32 ($a, $b, $c, $d, $e, $f) = (0 xx 6); « is the equivalent of » my int32 ($a, $b, $c, $d, $e, $f) = (0, 0, 0, 0, 0, 0); « 20:39
20:39 wamba joined
timotimo the default for int32 is also 0, so you can leave out the initialization if you want 20:39

Elronnd Xliff: nah, I found the issue, it was that I had the wrong number of args 20:45
I figured it out, works now
Xliff OK

[Coke] re: curly braces vs. square brackets (or parens or angle brackets) - suggestion for a word that covers the variety but isn't confusable with one of the individual kind? 22:39

reach_satori Is there something similar to beautifulsoup for perl6? 22:43
i'm trying (arduously) to learn it and a little web-scraper seems like a good first project
Geth doc: 0573fb5e69 | Coke++ | doc/Language/modules.pod6
whitespace
doc: 133c83753c | Coke++ | doc/Language/glossary.pod6
cover something that is not just a bracket
[Coke] what is beautifulsoup? 22:44
pypi.org/project/beautifulsoup4/ ?
reach_satori yes
