AlexDaniel does anybody want to organize a squashathon for the next month? 00:51
it probably makes sense given that everybody is staying at home? :) 00:52

uzl[m] Yeah, it really helps when modules that do graphical stuff show samples of what the result will possibly look like ;-). 01:00
BTW, I'm wondering how everybody decide when to access a `$.` attribute through its `$!` twigil vs its method (and vice versa). I'm always inclined to use its `$!` twigil form but few modules I've come across use the accessor form instead. I figured I haven't weighted my decision that much. 01:01
01:08 NODE left 01:10 NODE joined
AlexDaniel` uzl: yeah, I probably meant `$!` any time I wrote `$.` 01:12
uzl[m] AlexDaniel: 😂 Any compelling reason why one would use `$.` instead `$!` when accessing the attribute? 01:16
AlexDaniel` uzl: I'm not sure, but what happens when a subclass decides to override the attribute somehow? 01:18
01:20 squashable6 left 01:21 squashable6 joined
uzl[m] Not sure. Wouldn't that be delegated to the parent class's attribute? 01:22

Altreus Aren't all iterative solutions writable as recursive solutions? 09:33
09:46 [Sno] joined
chloekek All iteration can be implemented with recursion, but without tail call optimization doing such is inefficient. 09:52
dakkar I mean, any computable function can be rewritten as a `while` with a `switch` inside, but it's not often a good idea to do so 😜 09:59

tbrowder trying to port perl regex to raku: can anyone translate perl's "\G" to raku? 11:05
jnthn I think you'd just use m:g in Raku? 11:07
Though I may be forgetting exactly what it does
11:07 xelxebar joined 11:08 ptrcmd joined
tbrowder perlre says "match only at pos()" 11:11
where "pos() is the end of last end-of-match position of prior m//g" 11:13
so m:g sounds like it. in the actual code i'm looking at it may be trying to match internal start/end of lines because they are using the 'm' modifier 11:17
back to the task, thnx 11:18

Kaiepi i have a problem with tracing for assignments to any attribute of a type that i'm not sure how to solve 14:02
the way i deal with tracing of all methods of a type is mix in a role to the type's HOW with a compose method that wraps its methods either before or after composition depending on the type of method 14:03
but for attributes, i can't deal with it after composition, somehow the tracing gets lost
but if i do it before composition, then any roles' attributes that get mixed in won't get traced
what can i do?
atm i make the role mix in a compose_attributes method instead, but that doesn't work with punned roles 14:04

Kaiepi ah, wrapping compose and compose_repr seems to work 14:17

guifa2 uggggh. Setting up new machine and Catalina doesnt like rakudo star 15:05
lizmat doesn't like Catalina to begin with: it broke several of my workflows 15:11
and if that's the way Apple continues, then I'll be looking for other hardware / software to work with
15:12 silug left
jnthn The new notarization stuff for Catalina is causing us a lot of trouble with shipping Comma on MacOS too. Especially 'cus we had it all working, and then they ratcheted the requirements up even further. :( 15:14

El_Che I have a mac laying around (my train laptop :) ), I don't even know what release it runs :) 15:42
I had to spend a lot of work to make the shortcuts human on an azerty keyboard 15:43
macos just takes the qwerty shortcuts and use them as is on other layouts
so ctrl ` (alt tabbing withing same apps): the ctrl you use is on the left, the ` en the extreme right 15:44
useless
and the ` is also too close to the right ctl, so you need 2 hands
I ment apple key
synthmeat i don't know. i have same mac machine for 7 years now, regularly updated. incoparably better experience than linux or windows before that. 15:46
incomparably, even.
helps that i live in cli tho :D 15:47
El_Che is certainly easier to code than on windows
but I pain compared to linux
(in my experience)
windows is by far the better machine for games thoughs :) 15:48
synthmeat definitely. consoles are even better. :)
El_Che I have a nice workflow on linux for testing my code: I run containers with podman (non root) and run tests against them 15:49
tried it on mac
pure pain
the podman in brew is just a proxy to send to a linux docker host :)
and every time I install something with brew I feel uneasy, securitywise 15:50
synthmeat i just ssh into server for development
El_Che I commute
synthmeat all dev tools on desktop are just for "play"
El_Che and some parts are spotty
therefor I worked on getting I good setup on the mac
synthmeat mosh works fine for me during commute
El_Che (I work on linux at home and work)
synthmeat (not that i commute a lot tho)
15:50 mowcat left
El_Che well, I have code that talks to the keycloak api, Vault and uses a db 15:51
so the tests to be usefull, need to talk or mock that
synthmeat yeh, different types of devs all around the world
El_Che really having the services available to my tests makes me very efficient
event if we have whole the CI infra 15:52
synthmeat i don't write tests or have CI :)

lichtkind guifa2: yes but there are not there in classical sense (which i consider a feature) 19:17
thank you 19:18
19:23 chloekek left
nine Sure we have abstract types: 19:24
m: role ImAbstract { method foo() { ... } }; ImAbstract.new
evalable6 (exit code 1) Method 'foo' must be implemented by ImAbstract because it is required by roles: ImAbstract.
in block <unit> at /tmp/Tsm1KksfDA line 1
guifa2 I guess I was thinking in a traditional sense an abstract type all of the methods would be abstract, but maybe I'm misremembering other languages' approaches 19:27
lichtkind yeah you can instanciate roles and use that to mimick the dehaviour - good point thant steffen

uzl[m] vrurg: Yeah, you're right! I didn't know you could do that. By the way, what's the Raku equivalent of super from other languages (e.g. Python)? 23:29
vrurg uzl[m]: $. works since last Nov. There is no super, only dispatching. In specific cases one might use class-qualified call format. 23:30
23:30 guifa2 left
uzl[m] synthmeat: You might want to give a try to Think Raku (github.com/LaurentRosenfeld/think_raku). Also you might find useful info on Andrew Shitov's books. 23:31
synthmeat uzl[m]: my impression was that Think Raku is mostly for beginner programmers. that's not true? 23:33
uzl[m] vrurg: Oh, I see. I figured one could use redispatching (next(same|with) and call(with|same)), however I haven't seen it used that much myself. Any ecosystem module out there using them? 23:34
synthmeat i was thinking about moritz's Parsing… book, grammars look like lotsa fun to go in-depth
uzl[m] synthmeat: Mostly true. You could skip straight to the second part about grammars, OO and functional programming. However, there's always the documentation. 23:35
vrurg uzl[m]: Basically, they're everywhere. That's how you pass control in Raku. 23:36
Dispatching is not only about inheritance, but it's also about multi-routines and wrapping.
uzl[m] I should look more closely then. I've only seen on the docs and related blogs. 23:37
Oh, sure. I meant specifically the redispatching routines.
23:38 sacomo joined
uzl[m] synthmeat: I haven't read Moritz's book but looking at the TOC it seems to go deep into grammars; I'd daresay it's de-facto book about Raku grammars at the moment, Shitov is working on a Raku grammar-related book. 23:40
23:40 guifa2 joined
Grinnz keeps reading re-dispatching as redis-patching 23:40
synthmeat uzl[m]: surprisingly a lot of good resources for something so little used, tbh :D 23:41
love it. it's paradise.
uzl[m] link: andrewshitov.com/creating-a-compiler-with-raku/ 23:42
synthmeat: Do you mean Raku? Or its grammars?
synthmeat raku
i love it though. horizontally, it has every feature i'd possibly want. vertically, it has the extreme depth on most generic feature of them all, interpreting tokens (grammars). 23:46
uzl[m] Well, I think the fact so many people have put a lot effort into it means it has some potential. In any case, I guess Raku is a love project for the many people involved in it. Furthermore, the language is quite new and nobody knows what the future may hold. 23:47
23:47 leont left
synthmeat yeah, i'm quite enamored with it now 23:47
uzl[m] synthmeat: I feel the same way. I don't know if it's an illusion but Raku makes you feel things are at arm reach. 23:48
guifa2 I've switched to using Raku for almost everything I've been doing
synthmeat v8 performance spoiled me though. it's insane how fast that thing is.
guifa2 jnthn++ is getting us in that direction
23:49 pecastro left
uzl[m] (jnthn and all the people involved)++ 23:51
synthmeat here's hoping language consistency and not being chained to running in browser makes it much easier job (moar vs v8) 23:52
