kawaii I have a question! How do I write unit tests for my Perl 6 modules that depend on proprietary APIs (i.e. they require a key, or in a another case they require running some software which is the interface the module is designed to work with)? 18:55
timotimo you can perhaps mock the external stuff
kawaii You see, that's what Altreus suggested, but it seems harder than writing the module itself :/ 18:56
jmerelo timotimo: is there some module for mocking? Or just by hand? 19:00
timotimo there is a module
github.com/jnthn/test-mock
kawaii It might be viable in my case to create a mock API response for the first module, given that it should just spit out a very small amount of JSON. 19:01
timotimo also test how your module reacts to spurious errors :) 19:03
jmerelo timotimo: great!

El_Che tony-o: may I guve some constructive criticism? 19:53
tony-o please 19:54
El_Che People like me, the paranoid kind, prefer to see a link to the repo with the Dockerfile. So I can fork it and build it myself. Running third party images is a big no-no (beside upstream OSes) in a lot of places (including my team, because of me). 19:55
While at it, it also inspire confidence if the image is autobuilt from github
it's fairly straightfwd 19:56

camelia (timeout)new output
Skarsnik the supply is a loop
that probably why
ryanth What's the cleanest way to say `my @squares = 1², 2², 3² ... 10²;` ? Best I have is `my @squares = (1 ... 10).map: { $_² };` but I'm not sure if there's a more canonical way to achieve that. 21:16
Skarsnik but I used an example that has the supply and the loop not ina function and this worked
it's like supply { loop { get github notification; emit notification; sleep 60} } 21:17
ugexe m: my @squares = (^10)>>²; say @squares[4] 21:18
camelia 16
ryanth Ooh, nice. Thanks. I'm still thinking like a p5 programmer. :-) 21:19
21:20 MasterDuke left
ugexe im not saying that is the cleanest way though. that is arguable 21:20
ryanth Fair enough. It's certainly a way I didn't know how to do 2 minutes ago, though!
discord6 <Rogue> Cleanst in my personal opinion would be this: 21:21
<Rogue> my @squares = (1..10)»²
<Rogue> using postfix exponentiation and the hyper operator 21:22
21:22 cpan-p6 joined, roguelazer left
timotimo not cleaner, but a different approach that also works: (1..10) »**» 2 21:23
ryanth Yeah, that is nice, Rogue. Is 1..10 vs ^10 a personal preference in this case, or is there a reason behind it?
ugexe i was hoping * * * could be used somehow
Juerd ryanth: 1..10 and ^10 are not the same.
ryanth: ^10 is 0..9
discord6 <Rogue> ^10 actually is the same as 0..9 (or 0..^10)
timotimo (^10 + 1)
ryanth Ack, right, I was just reading off of Rogue's example. Hadn't fully thought it through yet. 21:24
timotimo m: ((1..10) »xx» 2).map(* * *).perl.say
camelia (4, 4, 4, 4, 4).Seq
discord6 <Rogue> .. is inclusive, but you can put a karat on either side to make it exclusive on that side, which is where the ^x shortcut comes from
Skarsnik hm, I guess it try to sink the loop? 21:25
timotimo m: (1..10).map({$_,$_}).map(* * *).perl.say
camelia (4, 4, 4, 4, 4).Seq
timotimo oh, duh
m: ((1..10) X 2).flat.map(* * *).perl.say
camelia (2, 4, 6, 8, 10, 12, 14, 16, 18, 20).Seq
discord6 <Rogue> I kinda wish .. was tighter than hyper ops 21:26
Skarsnik ugexe, How I can tell it that the @ emited is not the loop?
I mean it try to get everything emit the loop will provide as a single @ if I understand correctly
in the for @output part 21:27
timotimo emit should only ever "send one message" even if you have something with an @ somewhere

ryanth Heh, that's a bit naughty. I love it. 21:30
Skarsnik well the issue timotimo it get stuck after the say "getting some output"; in the process-stuff($_) for @outputs; I guess it's because the @output try to get all the loop?
timotimo let me have a look at the code 21:31
Skarsnik gist.github.com/Skarsnik/36d62955b...feaaaa7a20
I put the supply out the module function 21:32
timotimo the sleep is probably the problem 21:33
supply doesn't introduce parallelism on its own
Skarsnik but why the emit happend and I get the text Getting GH notification : True 21:36
Notifications : 1 events
this should not even trigger the begining of the whenever block at all if the sleep was blocking 21:37
21:38 MasterDuke joined, MasterDuke left, MasterDuke joined 21:40 cpan-p6 left
Skarsnik I though it will emit, process stuff that tap on the supply, then continue after the emit? 21:41
timotimo is $res<success> true? 21:42
Skarsnik yes
21:42 cpan-p6 joined
timotimo oh, you do get the whenever block run once 21:42
Skarsnik the beginning run
but not the gh-process-event
ugexe wouldnt you need whenever start supply { ... } ->
timotimo oh 21:43
Skarsnik I think the @event get the loop
and not just what is emited
timotimo could it be getting the number of entries in @events exhausts the underlying sequence and the for loop just after that just crashes, but the exception somehow gets swallowed?
21:44 roguelazer joined
Skarsnik dunno, it disrupt the rest of the supply 21:44
it crash on sleep $res<headers><X-Poll-Interval> || 60; because $res became Str 21:45
for whatever reason
21:45 roguelazer left, vrurg left
timotimo it's not $res that's the str, but the X-Poll-interval, no? 21:45
m: sleep "10" 21:46
hm, that does work
camelia ( no output )
Skarsnik Died with the exception:
Type Str does not support associative indexing.
timotimo could also be what headers returns 21:47
Skarsnik hm right
but still the for @events prevent the gh-process-event to run :(
like basicly it will crash after the sleep is done 21:48
ugexe the readme says
my %res = $http.get("www.cpan.org/");
not my $res
maybe that will fix it?
Skarsnik why? There is already use of $res<stuff> that work x) 21:49
ugexe i'd prefer to not have to figure out the answer if its not the case 21:50
Skarsnik nvm, it crash in the process-event, but still why it block for 60 sec when the say in the whenever block happend imediatly after the emit :( 21:54
21:56 reach_satori joined
Skarsnik I guess I could use a Supply.Interval? but can I change the interval? 21:57
ugexe because the emit happens before the sleep 60 the first time only?
21:58 [Sno] joined, [Sno] left, sno left, [Sno] joined, cpan-p6 left
ugexe my $stuff := gather for 1..^Inf { take $_; sleep 60 }; # of course this "blocks" for 60 seconds everytime except for the first 21:58
Skarsnik what happend : the supply emit the @event; the whenever block start (it say "getting notification 1") then it block for 60 sec before even processing the event 22:00
then crash because the event is somehow empty now

timotimo that looks good already
jnthn Except that it's in CORE.setting so needs to be in the lexical scope of CORE.setting 22:25
timotimo ah, ok
jnthn And wrapping braces around that probably means it isn't
timotimo in that case just have my \Foo = do { ... }
or even enum Foo ( do { ... } );
jnthn That'd make it runtime-bound, though...
Right, the do inside of there is the way :)
timotimo right, would have been constant rather than my \Foo = do ... 22:27

jnthn Skarsnik: What causes the interval to change? 23:25
Skarsnik github header that give you the interval to poll between 2 requests 23:26
jnthn So it changes for every request?
SmokeMachine Xliff: have you seen the possibilities I added? 23:27
Xliff Was just looking at them.
jnthn Perhaps something like sub do-stuff-with-interval($seconds) { whenever Promise.in($seconds) { ...do stuff...; do-stuff-with-interval $new-seconds } }
Xliff Not sure I get the point of 'Bla:ver<0.2>.a = “{ Bla:ver<0.1>.b } & { Bla:ver<0.1>.c }”'
Why the &? 23:28

SmokeMachine I was just concatenating 2 strings with a & between them... 23:28
Xliff Ah. OK.
SmokeMachine Just a example... 23:29
Xliff That's not bad, then.
But I still think that "migration" should be a ClassHOW
SmokeMachine None of them I’m sure it is possible...
Xliff That gives us methods for model level changes. 23:30
And field level changes can be handled in those methods.
Skarsnik I am legit confused
MasterDuke SmokeMachine: does Red support upserts? 23:31

MasterDuke SmokeMachine: ok, just idle curiosity 23:32
jnthn Skarsnik: sleep isn't a good idea in a supply/react generally; sleep blocks a real thread
Xliff SmokeMachine: Let me give it a little more thought. I think I may have an idea. 23:33
Skarsnik jnthn, So what the good solution to what I want : basicly react every poll of a github request (notification) I was thinking of setting the supply interval, but I don't think you can do that x) 23:35
ryanth What's a good, general way to unroll a lazy list (i.e., make it not lazy)? 23:36
O
jnthn Skarsnik: Probably the constrct I just showed you
Skarsnik: Or at least replace the sleep with an `await Promise.in($seconds)` 23:37
MasterDuke ryanth: assign it to a @ ?

Skarsnik jnthn, Can I do that in a supply or both need to be into a promise? 23:41

Not sure if it’s that Nil is being converted to a blank string (which I don’t think it should) and the hash is blissfully unaware, or if it’s the hash that decides to interpret it as a blank string (but in which case, it makes less sense to toss a warning) 23:57
