`String.sendChatMessage(ipsToSend: Map<String, Int>)` then `"Message".sendChatMe...
hm
surreal quarry
why is that ew?. you are sending a chat message to some ips that are stored in the form of Map<String, Int>

It's ew because it's not Java

No mutability

No
half harness
No mutability
oops
half harness
Dkim, you're not in Java
i know, what should i change
half harness
u guys aren't telling me what to do
surreal quarry
dkim you could do something like list.map probably or maybe list.associateBy. i forget the name
prisma wave
Make parseIpAndPort and then use .map for the list version
surreal quarry
instead of the mutability inside the method
prisma wave
^^
regal gale
The exception handling 🥲
surreal quarry
but BM what do you have against extension property here
astral quiver
with this approach with inline classes you can void logging in some cases
prisma wave
but BM what do you have against extension property here
Possibly nothing actually
I might have misunderstood
ocean quartz
i know, what should i change
fun List<String>.getMapFromIpAndPorts() = associateBy {
val (ip, port) = it.split(":")
ip to port.toInt()
}
Much nicer
surreal quarry
val List<String>.ipAndPorts: Map<String, Int>
get() = mapNotNull { it.split(“:”).getOrNull(0) to it.split(“:”).getOrNull(0).toIntOrNull() }```when we are doing debug log, sometimes we need alot of information and we need to proccess this information, like, mapping a values of a big list
half harness
```kt
fun List<String>.getMapFromIpAndPorts() = associateBy {
val (ip, port)...
what in the world is that
half harness
```kt
val List<String>.ipAndPorts: Map<String, Int>
get() = mapNotNull { it....
“ < "
surreal quarry
idk if what is sent would work even
prisma wave
```kt
val List<String>.ipAndPorts: Map<String, Int>
get() = mapNotNull { it....
Matt's looks nicer imo
ocean quartz
Yeah
surreal quarry
yea it does
ocean quartz
Don't think that'd make too much sense to be a property
prisma wave
Yeah properties should only be for short stuff imo
astral quiver
with this inline function format for logging, you avoid execunting something for just logging
half harness
fun List<String>.getMapFromIpAndPorts() = associateBy {
val (ip, port) = it.split(":")
ip to port.toInt()
}
```what does:
- associateBy do
- (ip, port) do
- ip to port.toInt() doassociateBy converts a List to a Map with a given function
obtuse gale
We know
surreal quarry
associateBy will associateBy
(ip, port) de structure
port.toInt()... i believe in you
half harness
i know what (ip, port) do
prisma wave
Then why did you ask
surreal quarry
you asked what it did
half harness
but now i dont know what ip to stuff does
stuck harbor
"getMapFromIpAndPort" christ
half harness
Then why did you ask
well i didn't know when i asked
i do now
because u told me
i think
prisma wave
but now i dont know what ip to stuff does
Open in IDE and look at the to function
It's for maps
surreal quarry
blah to blah creates a pair
distant sun
to is an infix for Pair.of()
half harness
i can't
stuck harbor
just call it "d" and make people look at the docs
astral quiver
the to creates a Pair
prisma wave
Constructing Pairs
prisma wave
Then read docs
distant sun
a to b = Pair.of(a, b)
astral quiver
associateBy requires a Pair if I recall
surreal quarry
every time
half harness
ill think abt it
prisma wave
associateBy is for (K) -> V and making a Map<K, V>
You want map() and toMap()
I think
obtuse gale
@obtuse gale
ocean quartz
Actually associateBy wouldn't work there, it'd be associate instead
half harness
```kt
fun List<String>.getMapFromIpAndPorts() = associateBy {
val (ip, port)...
@half harness
prisma wave
Yeah associate works too
ocean quartz
Associate prints {411.545.1.2=8000, 152.651.5.245=6000}
AssociateBy prints {(411.545.1.2, 8000)=411.545.1.2:8000, (152.651.5.245, 6000)=152.651.5.245:6000}
astral quiver
associateBy is for (K) -> V and making a Map<K, V>
I think this is associateWith
surreal quarry
doesnt that mean its going from (K) -> V into Map<V, K>
not (K) -> V into Map<K, V>
jovial warren
associateBy basically takes a list and associates its elements by some key
so you go from some List<V> to a Map<K, V>
prisma wave
uh oh
old wyvern
All types would have to be a resutl type or we will need it to be an expression
jovial warren
associateTo does the opposite, it takes a List<K> and transforms it into a Map<K, V>
old wyvern
Otherwise theres no way to find invalid matches
jovial warren
then associate takes any List<T> and transforms it into a Map<K, V>

old wyvern

Something like bind would be cool to pipe further things on the result
prisma wave
yeah
Tbh I think we should probably rework a lot of things if we want to go deeper into the functional side
Like when we made it, neither of us really understood FP I think
old wyvern
yea true
jovial warren
right, I gotta figure out how I want to do this now lol
a single entry point means I probably need to expose the loading stuff to the API
which sounds a bit whack
since a top-level function can't be abstract
surreal quarry
i dont think you do?
jovial warren
maybe I should take a different approach
surreal quarry
especially if its event based
jovial warren
either DI or single entry point, those are my thoughts
jovial warren
especially if its event based
I'm thinking in having the startup logic be a function that's called, but everything else can be event-based
surreal quarry
just have plugins listen for a startup event as the fun main()
You can load the plugins in the backend. you shouldn’t need to expose any of it
hmm
jovial warren
I was first thinking of just having the function take a context param that's injected when the function is called, but that gets a bit whack
then I thought of having main call a top-level function that takes a higher order function as an argument (say PluginContext.() -> Unit for example), but that would need to call something
and that wouldn't really work
surreal quarry
i think the context could be very nicely provided via the startup event.
the developer can create a top level variable of the context or something which can be used throughout the plugin to get things like the server, descriptor, etc
jovial warren
that gets a bit whack though
also, as I said, I'm not sure about having the startup logic be event-based
since that just once again increases boilerplate
surreal quarry
i dont think it does?
jovial warren
fun main() {
onStart(SomeEventHandler)
}
```or something to the equivalentyou would have to copy and paste that everywhere
surreal quarry
lateinit var context: Context
fun main() = listen<StartupEvent> { event ->
context = event.context;
// blah
}```yeah that looks a bit whack though tbh
first, you'd have to copy and paste that everywhere (unnecessary boilerplate imo)
second, using a lateinit var where you really shouldn't have to
old wyvern
Why not be a sane person and do what all frameworks do with an entry class dedicated to the plugin?
surreal quarry
why do you copy paste that everywhere? It’s less boilerplate than a class even if you do, but you dont.
// example event listener file
fun listenToMoveEvent() = listen<MoveEvent> {
//blah
}```
then just call `listenToMoveEvent()` in the startup event listenerif you mean ```kotlin
class MyPlugin : Plugin() {
init {
// some initialisation stuff
}
}
surreal quarry
you said it had too much boilerplate when you inject the server, description, etc
jovial warren
that's not what I meant by that
I meant ```kotlin
class MyPlugin(
val server: Server,
val folder: File,
val description: PluginDescriptionFile
) : Plugin(server, folder, description)
pls no
Make var illegal
surreal quarry
right. how do you avoid that?
i’m sure there’s a better way BM i was just writing something quick as a proof of concept
jovial warren
that's what I'm trying to figure out
ocean quartz
I mean use Koin if you feel like it'd be better
surreal quarry
i’m saying you avoid it with a startup event
jovial warren
I mean use Koin if you feel like it'd be better
what would that look like with Koin?
surreal quarry
you are saying you won’t do that because its too much boilerplate
jovial warren
the constructor thingy is yeah
surreal quarry
you said startup event is too much boilerplate
ocean quartz
Idk Koin too much, but from the example it'd look something like
class MyPlugin : Plugin() {
private val server: Server by inject<Server>()
}
yes ik
prisma wave
I mean use Koin if you feel like it'd be better
vomtigin_face
half harness
jovial warren
Idk Koin too much, but from the example it'd look something like
```kt
class MyP...
yeah idm that but BM will kill me for using property-based DI lol
also, boilerplate
old wyvern
Would using them in the parent class work?
ocean quartz
Btw @half harness that code I sent you will throw at least 3 errors if you don't do the pattern correctly
half harness
oh-
jovial warren
Would using them in the parent class work?
using the injections and then registering the plugin's main class as a Koin module? sure it would
half harness
Btw <@!521485088995672084> that code I sent you will throw at least 3 errors if ...
how do i do it correctly?
jovial warren
so I could use property-based DI in the super and then boom, no boilerplate in the impls
surreal quarry
dkim the error would probably be index out of bounds
prisma wave

it is
jovial warren
nah but you probably shouldnt be forcing users into that
forcing users into what?
old wyvern
Using Koin
surreal quarry
event driven api :)
jovial warren
it is
not having to do property-based DI yourself by me doing it myself on the backend is probably the best way to avoid boilerplate injection here
ocean quartz
how do i do it correctly?
You'll need some checks, for example 152.45.02.11 will IndexOutOfBoundsException, 152.45.02.11:sdasd will NumberFormatException
prisma wave
not having to do property-based DI yourself by me doing it myself on the backend...
it's still property DI
however you choose to hide it
surreal quarry
oh bardy. you could eliminate the lateinit var by providing the context in every place in the api. all events have it, commands have it, etc
jovial warren
oh bardy. you could eliminate the lateinit var by providing the context in every...
true, but then I risk compromising the constructor
and yet again running into the same issue
surreal quarry
wdym compromising the constructor
jovial warren
class MyCommand(private val context: PluginContext) : Command(context, name, permission, aliases)
DSL commands >
surreal quarry
command event 
jovial warren
if me using property-based DI on my end means my end users don't have to use constructor-based DI themselves then I'm willing to accept that
astral quiver
command("hey") {
}
yeah I'll have that too
I already have a DSL for Brigadier, so this would go with that
old wyvern
The other way would be to provide the plugin with something like a "PluginManager" and let the super constructor register itself
ocean quartz
Alternatively you can just do like Bukkit and have the server as a singleton 😬
old wyvern
and thus load whatever is needed
jovial warren
Alternatively you can just do like Bukkit and have the server as a singleton 😬
that's not what I want
prisma wave
when are you embedding the clojure script engine
jovial warren
also, that's the exact thing I'm trying to avoid by dependency injecting the server
old wyvern
All this wouldnt be a problem if you just embed Elara actually
define variables and execute
🙂
jovial warren
I want to strongly encourage DI and strongly discourage singletons
which is why I should probably just embed Koin tbh

jovial warren

spring heavily discourages it
prisma wave

what
you're acting like proper DI is impossible
old wyvern
class MyPlugin : Plugin(
"MyPlugin",
listOf(MyCommand::class, MyOtherCommand::class),
listOf(EventListener::class, OtherEventLister::class),
)
Spring do that, Dagger do that, Koin do that, Kodein do that
jovial warren
you're acting like proper DI is impossible
it's not, but it's going to increase boilerplate
prisma wave
Spring heavily discourages it, Dagger also discourages it, Koin doesn't, which I consider a problem
jovial warren
as I said, I would rather me suffer than the users of this suffer
astral quiver
I don't do that, but all top usage DI frameworks do that
prisma wave
Kodein is even worse
prisma wave
it's not, but it's going to increase boilerplate
by an incredibly marginal amount
who cares about having to override a constructor
big deal
astral quiver
Spring heavily discourages it, Dagger also discourages it, Koin doesn't, which I...
I will need to check the documentation again, because I learn to use Koin/Kodein as a constructor injection
prisma wave
Kodein's github only shows property based
if Koin supports actual constructor injection that's nice
astral quiver
also, KodeinAware and KoinComponent SUCK
prisma wave
but my other issues with it still stand
jovial warren
Koin makes you do all the instantiation yourself
that's also one thing I kinda like about Koin
no black magic
astral quiver
if Koin supports actual constructor injection that's nice
The first one that you learn in the Koin documentation is constructor injection with modules
jovial warren
beautiful
old wyvern
in Android, it is required
eh?
jovial warren
also, even though it seems to be against the law apparently to do property injection, I still think it looks really nice
astral quiver
you can't instanciate a Application, Activity
old wyvern
You dont need koin at all
jovial warren
it just feels a lot cleaner
old wyvern
Thats pretty much equivalent to using singletons
prisma wave
yeah
old wyvern
Just waiting for Android to wipe everything clean
prisma wave
that's not dependency injection
old wyvern
mhm
astral quiver
well, ServiceLocator is that
old wyvern
Which?
astral quiver
using a singleton for DI
old wyvern
yea that not much of a great idea
astral quiver
In android, you can't run from property di
you can't create a custom constructor for Views (if you want use it in XML)
ou can't create a custom constructor for Activities
old wyvern
You dont use di in android
Atleast not in the same sense
you consider your activity to be the root element
And pass on dependencies to its dependencies
astral quiver
Application is the root element
astral quiver
and for Views?
old wyvern
Except for maybe with sticky services
old wyvern
and for Views?
What about them?
astral quiver
what do you do, how you get the dependencies?
old wyvern
If dynamically created just with constructor I assume?
If thorugh xml, pass in the properties you can
astral quiver
you can't pass property meaningful through xml
old wyvern
And if Views have access to the acitivity lifecycle probably hook into viewmodels?
old wyvern
you can't pass property meaningful through xml
Youd use other patterns to supplement those requirements ussually
Like Adapter for eg
astral quiver
Adapters you can instanciate
old wyvern
Even without viewbinding?
old wyvern
but, with Custom Views is not the same
Not sure what you are reffering to?
old wyvern
yea
astral quiver
is different from custom view
old wyvern
Whats the issue with inflating the view?
astral quiver
a Custom view, inflates a view, but its a custom view
inflates a layout*
is not the same
old wyvern
I didnt same they were the same*, i asked what would be the issue with inflating
astral quiver
You are questioning basically every single android application in the world
This is a commum use case in Android, you can't run from it
old wyvern
You are questioning basically every single android application in the world
In what sense?
astral quiver
saying that "is not required to use property injection"
old wyvern
This is a commum use case in Android, you can't run from it
Dependening on singletons is waiting for a disaster when android destroys and rebuilds the application
astral quiver
still does not understanding you are saying, there is no singletons when you use Koin in Android
old wyvern
What im saying is that there are work arounds to providing them in the normal sense which is seen throughout the provided API
astral quiver
you just startKoin on your Application class
old wyvern
still does not understanding you are saying, there is no singletons when you use...
Yes but a lot of the dependencies end up being "single"'s
astral quiver

old wyvern

The applications can continue inbetween after being destroyed sadly
You might not even rehit the point of "startKoin" I assume
old wyvern
As in when the battery manager temporarily kills the process
And reopens in the same state
astral quiver
Application class is not destroyed so easy
the Application class will run again, and the startKoin will also run again
old wyvern
Pretty sure Application is supposed to be similar to singletons
There is normally no need to subclass Application. In most situations, static singletons can provide the same functionality in a more modular way. If your singleton needs a global context (for example to register broadcast receivers), include Context.getApplicationContext() as a Context argument when invoking your singleton's getInstance() method.
astral quiver
They are, and what is the problem with that?
old wyvern
I assume they follow the same lifecycle if they were to recommend that
astral quiver
oh, I guess I get your point
old wyvern
They are, and what is the problem with that?
The issue being the same, that state being lost when the user is in an activity or fragment that expects a dependency in a certain state
astral quiver
You mean: in any place I can find my Application class and uses my dependencies in their?
jovial warren
oh btw, what do you guys think about the idea of a plugin.yml like Bukkit's anyway?
astral quiver
The issue being the same, that state being lost when the user is in an activity ...
This is not a problem for DI, this is a problem with Android, you should use saveInstanceState for that
jovial warren
still thinking actually whether I should just use annotations tbh
old wyvern
saveInstanceState wouldnt work for the injected dependecies I assume?
astral quiver
I don't can't your point with losing state, this happen alot, but DI does not have anything with that
old wyvern
Im not saying DI has to do with it
astral quiver
I should not work with
old wyvern
Im saying relying* on DI will lead to places where a few expectations break
astral quiver
Koin uses Kotlin Delegate for the dependencies
jovial warren
old wyvern
Atleast in the form of injecting that way
old wyvern
Koin uses Kotlin Delegate for the dependencies
Yea
astral quiver
`as?` superior
Yes
prisma wave
`as?` superior
that's different
astral quiver
but, I should be a KotlinBukkitAPI instance or not find it
if there is some plugin with KotlinBukkitAPI name
jovial warren
if that returns null, you can't cast it to a nullable type, since apparently, according to Kotlin, null is not nullable lol
actually wait what am I reading
lol that confused me
astral quiver
getPlugin can return null
jovial warren
yeah ik
astral quiver
if the Plugin instance is not KotlinBukkitAPI, I want the cast issue
jovial warren
so you cast to a nullable type
astral quiver
but, I would use a better error message to do that
jovial warren
anyway, what do you guys think of me using a plugin.yml btw?
astral quiver
No, do it like Sponge does
astral quiver
yes
jovial warren
also, if I was going to use annotations, I could literally remove the use for any whacky loading logic anyway I swear
jovial warren
yeah the annotations get a bit whack with a lot of dependencies and big info text
jovial warren
for CI/CD propose
and that, yeah
astral quiver
like: publish with a commit version
jovial warren
also, should I do a Bukkit and require a main entry in the plugin.yml
I mean, the only other option I really have is classpath scanning I guess
which would be fucking slow to do at runtime
right, main it is then
astral quiver
Release it with a Gradle Plugin, needing to write a plugin.yml sucks
jovial warren
guess I could take the project name and version and use those to generate a plugin.yml?
jovial warren
or maybe just ```gradle
plugins {
id 'org.kryptonmc.plugin-config' version '1.0'
}
group 'me.lucko'
version '1.0'
pluginConfig {
name 'LuckPerms' // defaults to project name
main 'me.lucko.luckperms.krypton.KryptonLuckPerms'
version '1.0' // defaults to project version
}
TOML doesn't deal with nested structures very well
and JSON would be annoying to write
also, what's wrong with YAML anyway?
I mean, I can say that the YAML specification can be very lenient sometimes, but for the most part, I think it's really nice
I will support a multitude of formats for configuration
obtuse gale

TOML sucks!

and I thought YAML's specification was lenient lol
okay this is actually quite nice
how do arrays work in HOCON?
e.g. json "authors": [ "lucko", "BomBardyGamer" ] in JSON, or ```yaml
authors:
- lucko
- BomBardyGamer
is there a way to do something like that in HOCON?
jovial warren
how do you do arrays in HOCON?
actually nvm, got it
authors = [
"lucko",
"BomBardyGamer"

it's basically Bukkit minus the useless crap
a.k.a database, load, the single author string, website, prefix, and commands
the things you don't need
jovial warren
load is going because there isn't two loading states like there is in Bukkit
half harness
what is prefix?
jovial warren
prefix changes the logger name
half harness
what is database?
jovial warren
e.g. ```
2021-03-09 18:19 - [MyPlugin] hello there!
something that should have been removed years ago
jovial warren
it's basically what happens when Bukkit tries to make an ORM for accessing SQL databases
and that went as well as you could expect
half harness
Using MySQL increases chances of server crashes unless the database is hosted externally. Your server(s) can crash from reaching maximum HDD space allocated to your server.
epic
jovial warren
as I said, useless feature that should've been removed years ago
since we've moved out of the time where databases were a pain to get hold of or run yourself
oh btw, does HOCON by any chance support optional lists?
because that would be perfect for the authors lol
e.g. you can either have it be a string (single element), or a list (multiple elements)
probably not, but idk lol
also, should I support all the default values Bukkit does for permissions btw?
or should that just be a boolean
I mean, do I really need default states like op and notop?
they seem pretty useless tbh

wtf even is a monad
In functional programming, a monad is an abstraction that allows structuring programs generically. Supporting languages may use monads to abstract away boilerplate code needed by the program logic. Monads achieve this by providing their own data type (a particular type for each type of monad), which represents a specific form of computation, along with two procedures:
One to wrap values of any basic type within the monad (yielding a monadic value);
Another to compose functions that output monadic values (called monadic functions).[1]
Optional in Java is technically a monad
