.landyacht. docs.raku.org appears to be down 02:08

coleman I think I've fixed the docs site now 02:14
02:14 landyacht joined, landyacht left
.landyacht. yep, working now 02:14
02:15 hulk left, kylese joined
on a related note, on my browser (desktop firefox running on linux), the main content of the docs site is shifted over to the right such that part of it is off-screen 02:16
turning off .container { max-width: 1140px; } under the >1204 @media selector fixes it 02:17
coleman mind filing a bug at github.com/Raku/docs-website 02:23

vasko SmokeMachine That sounds pretty good. Exactly not every Cromponent/Component needs a URL + methods does it? Some might just be used a a subcomponent shared between multiple resources. 10:02

sjm_ Hello channel, I would like to see if Raku can be used for a couple of new projects. One is a simple web service, the other will use Sparrow (Thanks for the suggestion Liz). I am looking for a minimal docker compose file that will run these, so seeking your suggestions. 11:18
lizmat sjm_ o/ 11:20
sjm_ lizmat o/ 11:25
lizmat librasteve might have some ideas for you 11:37
wayland melezhik might also have some ideas. 11:55
sjm_ great. I ahve created a container however :q 11:59
seem to be getting stuck with dependancies
11:59 [Coke] joined
sjm_ Maybe if I can get some help on the zef modules that I should install would unblock me. 12:00
I am using Debian Trixie as the base image
lizmat what does raku --version say ? 12:01
sjm_ Welcome to Rakudo™ Star v2025.02. 12:02
Implementing the Raku® Programming Language v6.d.
Built on MoarVM version 2025.02.
lizmat ok, so that's relatively recent 12:03
so that came with zef
what is the error message you get wrt dependencies ? 12:04
sjm_ this: failed to solve: process "/bin/sh -c zef install PrettyDump Test::Deeply::Relaxed Test::Output LibCurl URI Digest::SHA1::Native Text::MiscUtils Method::Protected Test::Run \"Rainbow:ver<0.3.0+>\" File::Directory::Tree Test::META" did not complete successfully: exit code: 1
I have removed some dependencies to see if I can narrow it down 12:05
lizmat that would be helpful
need to go afk, so hope someone else will be able to help you & 12:06
sjm_ thanks Liz
tbrowder Voldenet: ref Pod::TreeWalker, i've asked the original author, Dave Rolsky, for his opinion on the "is required" trait. 12:10
sjm_ actually with less deps, the container builds, so I will come back if there is something that I need that doesn't build. Also will share the docker recipe if it works (and the minimal CMS app). 12:15
Voldenet tbrowder: I have no strong feelings about `is built` - it works, but I use 'new' instead anyway 13:28
tbrowder thnx 13:38

Xliff \o 14:12
tellable6 2025-05-03T16:13:31Z #raku <wayland> Xliff: Under what conditions? Is .r a method? Does it exist? Are you calling it?
Xliff Does raku track the dependencies of a given module?
I see this comment (irclogs.raku.org/raku/2019-10-23.html#10:53) from Kaiepi in 2019, but would like to use a module's name rather than its file path. What's the best way to accomplish this? 14:20

tbrowder i know you can collect them via zef 14:57

librasteve sjm_: hi! welcome to the fun house 15:54
sjm_ Hello librasteve! thank you. 15:56
librasteve on simple web service, the active framework options are raku.land/zef:rawleyfowler/Humming-Bird or cro.raku.org ... HB is lightweight, with Cro you can make HTTP services with eg web sockets
yw
sjm_ for the Sparrow app, I will try Cro 15:57
librasteve ok - please feedback your experience ... we are always aiming to improve 15:58
sjm_ what would have helped is a simple docker compose. I have created one and once verified as working, I can share 16:00
librasteve chatgpt.com/share/68178f19-6d8c-80...2741e329b4 looks about right for minimal web service (I don't see a use JSON::Fast so you may need to add that (there are also some Class <=> JSON tools over at raku.land you can search for) 16:02
sjm_ Thanks - will add JSON::Fast and anything else required. The solution must only use existing packages and not try to build anything. 16:03
librasteve I have not got around to making a docker compose for Cro - when I get to it my aim is to automate this github.com/librasteve/Air-Play#build (ie you should be able to follow these manual steps yourself and then automate most of it in docker compose - the rest in sparrow) 16:04
sjm_ what's picocss.org/ (site doesn't load) 16:06
librasteve s/org/com please can you point me to the error 16:08
(yeah there's a few things in Air such as SASS for Pico CSS) that you don't need 16:09
sjm_ readme line 50
from picocss.org
The site at picocss.org seems to be unavailable. 16:10
librasteve sorry that's a typo - should be picocss.com
please can you point me to the page where I made that error 16:11
sjm_ github.com/librasteve/Air-Play/blo...md?plain=1
librasteve ok fixed - tx!
sjm_ yw 16:12
librasteve also you can ignore anything related to installing Air and Red since you just want Cro 16:13
sjm_ will do. I think I am starting from something much simpler, but could then go on to build what you have here. Will test over next days and let you know. 16:15
librasteve btw - you don't have to run cro behind a reverse proxy like nginx unless (i) you want to make https / letencrypt easier or (ii) you want to reverse proxy for scalability
[I wanted (i) when I chose this setup] 16:16
sjm_ indeed - my infrastructure has edge proxies which manage ssl and some other housekeeping. I will be replacing nginx with sozu soon. 16:17
librasteve oh - i was planning to go from nginx to caddy - will take a look at that (simple letsencrypt is really all i need)
SmokeMachine sjm_: this may help (and I think it already creates a dockerfile for you): cro.raku.org/docs/cro-tool 16:18
librasteve good point!
sjm_ librasteve maybe not sozu than, it's main feature is the ability to send config to it live without restart. You may want something simpler. 16:20
SmokeMachine - thanks, will take a look 16:21
librasteve simple is good
if we had a docker-compose that could deploy from cro stub Dockerfile.yaml that would be very cool 16:23
SmokeMachine sjm_: if you end up liking Cro templates, you can also take a look att cromponents (but only if you like Cro templates… I’m not trying to show more options just to make it more complicated)
16:32 phogg` is now known as phogg
sjm_ I have two projects - one is a simple headless multi-site markdown cms, and the other is a more complex orchestration API service with a UI, and using Sparrow for remote execution. This is less about UI and more API. I believe I need Cro for the second, still learning. 16:36
librasteve sjm_: one last thing (thinking about it at bit) - the steps to do to go from install raku (which iiuc is done by Sparrow) to get Cro running (on AWS clean ubuntu 24.04LTS) are set out here github.com/librasteve/raku-CLI-AWS...akumod#L40 ... well lines 46-52 can be done better with sparrow - it's line 54 and then 56-59 that are prerequisites for 16:37
Cro
sjm_ I see, sparrow to install raku 16:38
I am using chatgpt to help get this started. Once concept is proven, 16:39
librasteve yeah Sparrow should get you to install raku and then run local cmds to install the other deps
so you will need to take my 4-5 lines of perl and convert to Sparrow
(dunno hw to do that ;-() 16:40
sjm_ ok, I will spend more time on this over the week, and feed back progress
librasteve then use Sparrow to load and run the Dockerfile made by Cro stub
sjm_ I may need to get some professional Raku support, assuming my concept is proven. For various reasons, I can only pay a french tax payer so if anyone knows of a French Raku dev, drop me a note please 16:41
librasteve that should run easily on http ... then for https should be able to add reverse proxy (eg my nginx example) or feedin cert info via Sparrow setting ENV for certificate / port info 16:43
sjm_ ok - that is all I can do today, will be back here in the week with updates, or for more help 16:44
thanks all for your help
librasteve anytime 16:45

Voldenet hm, I thought about how `is built` works and if I were to build a proper DI container, how would I find out the actual dependencies of a class? 17:47
`.^find_method('new').signature.param.map(*.type)` works in the trivial case where I use `new` for everything 17:48
erm, `.^find_method('new').signature.params.map(*.type)` 17:49
and this obviously won't work when class has `is built` 17:50
lizmat why wouldn't it ?
tbrowder Voldenet: I heard from Dave Rolsky and he said he hadn't looked at the code in a long time and all he rembers is he worked on it. No comment on the "is built" trait vs "is required" 17:52
Voldenet m: class Foo { has Str $!test is built }; Foo.^find_method("new").signature.params.map(*.type).say
camelia ((Mu) (Any))
Voldenet it simply doesn't have the Str, probably the *%_ gets passed down
m: class Foo { has Str $!test is built; method new(Str :$test) { self.bless(:$test) }}; Foo.^find_method("new").signature.params.map(*.type).say 17:53
camelia ((Foo) (Str) (Mu))
tbrowder lizmat: have you seen my PR for Pod::TreeWalker? if so, any comment on "is built" vs "is required" there? 17:55
lizmat didn't look in depth yet 17:56
Voldenet m: use nqp; class Foo { has Str $!test is built }; Foo.^attributes.grep({ nqp::getattr_i($_, Attribute, '$!is_built') }).map(*.type).say 18:24
camelia ((Str))
Voldenet that's a thing of beauty

lizmat Voldenet: too bad nqp is needed for that... I guess an accessor method in the Attribute class would be needed 19:06

lizmat if someone would make a PR to make an Attribute.built method, I would definitely merge that (and possibly for other Attribute attributes as well 19:10

tbrowder my naive take on Pod::TreeWalker: is there a practical use for the “is built” trait using this distro? if so, let’s put it in the README and create a test for it. 19:53
