matt is this just a fun project ur doing? im not sure why ur making it 😅
its very cool tho

It's going to be a lib, making it so i can use on my plugins but also for anyone else who wants to use
Would be a cool chat plugin
ocean quartz
if clip wants he can use it

I really like the idea of having a convenient markdown-style language for mc chat. Let us know when it's public, I'll definitely use it
prisma wave
Yeah it seems very handy
ocean quartz
Will definitely do!
Gonna have to change it a bit if i want to do gradient
Also a bit worried about performance, doesn't seem awful right now, but needs more tests

you ever just looking over your code and you remember a monstrosity of a method that you wrote not too long ago
https://prnt.sc/txjxqf
what have I done it just got worse https://prnt.sc/txjyjj
tranquil crane
ended up renaming it to getPossibleStackableBlockMaterials() so I wouldn't keep making it worse
it was fun while it lasted
obtuse gale
If you keep extending the name, there's a point it's more readable to just inline the stream method instead of wrapping it in another method
tranquil crane
yeah I know, it's only ever used in one spot, I mostly just did it for organization but then it quickly grew into a joke

Take into account here the api design, which is the best?
Because most criteria never have children
Only a few will
API is the criteria class
Two snippets are to show how the criteria is structured

Fellas, using Monitor and not actually modifying the state of the event just sending a message if a condition is met should be fine right? (To ensure nothing else modifies it afterwards)

@hot hull Save EquipmentSlot as the key, instead of a String

How do I declare the default getter as private and override it with a custom public one in Kotlin?
lunar cypress
You don't, as far as I'm aware
empty flint
When the member attribute is declared in the primary constructor
You don't, as far as I' aware
@lunar cypress Kotlin bad then...
prisma wave
When the member attribute is declared in the primary constructor
not possible
there is a workaround
although i'm not sure why you need this
class SomeClass(blah: Type) {
val blah = blah
get() = blah.something
}
``` ?Well subclasses don't have access to private
@lunar cypress It has nothing to do with subclasses
lunar cypress
You talked about overriding
empty flint
overriding its own default getter
I basically don't want a getter for an attribute of a class
and a separate method to get and set the value
lunar cypress
wait what
empty flint
whatever, I think what Clojure did might work
prisma wave
write what you want to do in java
lunar cypress
You don't want a getter but a method to get the value
I think the terminology you're using is a little misleading
empty flint
Maybe I'm going at this all wrong
So I have a mutable map in a class
I don't want any outside class to be able to just change the values in the map directly
I want them to use methods to do it
so I want the map to be private
heady birch
no not possible
empty flint
and a getter and setter used to make changes within the map
heady birch
nothing works
empty flint
nothing works
@heady birch shut up 😄
prisma wave
but that's not a getter and setter?
hot hull
Any reason why you don't want people to directly change the map?
empty flint
but that's not a getter and setter?
@prisma wave No, it's not

kotlin class ClassName(private val map: MutableMap<Blah, Blah>) { fun put(key: Blah, value: Blah) { map[key] = value } }?

modules?
ocean quartz
Yeah, so for example if you don't want italic, you can disable it

yeah, have it takes excluded rather than included modules

How's pdm going?
lunar cypress

apart from the lack of relocation it's going pretty well
onyx loom
more than 0,.0.2 now
prisma wave
I had to skip 0.0.2 lol
onyx loom
were on 0.0.12 
prisma wave
I published to gradle and it failed and wouldn't let me try again
so I had to skip to 0.0.8 lmao
frail glade
Can I get a TLDR of the changes from 0.0.1?
ocean quartz
Was thinking about both yeah, just gotta think of a good way to do it
onyx loom
i would like that too
empty flint
What's pdm?
onyx loom
downloads dependencies at runtime
ocean quartz
Message.withModules(whitelist);
Message.withoutModules(blacklist);
This sounds pretty dumb right? xD
prisma wave
mostly bugfixes
the gradle plugin is a lot more reliable now (doesn't need kotlin plugin etc),
a few refactors (you use PDMBuilder instead of making a PluginDependencyManager now)
Johnny added some method that means you can do dependency loading before the plugin actually gets loaded
it supports parsing <parent> tags so things like Jackson should work
errant geyser
Matt, I'd have them all enabled, and then if they don't want certain bits, have a way to unregister the modules
prisma wave
and might be a little bit faster too
frail glade
So can I just put this onLoad and let it do its thing now?
lunar cypress
Yeah, but it doesn't make a difference unless you use code from dependencies on class load
Which is what I needed
lunar cypress
Before any dependency is used
That's the most important part
Would make sense in onLoad rather than onEnable of course
prisma wave
normally you probably want onEnable just so you can callback any initialization
frail glade
I would've thought 1.4 Kotlin be out by now.
prisma wave
😦
frail glade
I know it's in RC
prisma wave
yeah it's close
frail glade
Did you look at the stuff I sent you?
How he was downloading from json and just relocating when it's loaded it?
lunar cypress
No callbacks needed if you just slap a join there 😎
frail glade
Loaded in*
prisma wave
oh yeah, I'll probably end up doing something similar
frail glade
Waiting on the day relocation works (:
prisma wave
although i'm gonna try and look into classpath isolation, which might be better than relocation
iirc lucko does something like that but only for a few dependencies
lunar cypress
Never heard of that
prisma wave
I really hope that's possible bc it's probably a lot easier than relocation lol
frail glade
So does that just mean you don't relocate in the shadowJar?
prisma wave
yeah I think it would mean that each plugin has its own classpath and can't interact with classes from other plugins
making relocation redundant
not sure how possible it is though
frail glade
Might be more of a headache
ocean quartz
Like this?
frail glade
Yeah I ended up fixing the jar size by simply removing runtime from everything and then runtime Kotlin. That alone made the jar small enough 😂
prisma wave
that'll do it lol
lunar cypress
What if you have compileOnly dependencies like apis from other plugins
frail glade
Okay so July 27th was Kotlin 1.4RC

How do compile-time unknown generics work in Kotlin?

@heady birch you should just be able to call functions on the arc directly
prisma wave
@lunar cypress https://github.com/knightzmc/pdm/blob/master/CHANGELOG.MD
lunar cypress
And use read()/write() respectively
onyx loom
@prisma wave wrong date mate

Which is more appropriate, considering:
- lots of threads writing very quickly
- 1-2 reading every now and again

Is there a kotlin way to do this better?
contextualValues.toSortedMap().values.first()
If contextualValues is an empty map it will result in a "NoSuchElementException". In java I'd check this with an inline-if
contextualValues.empty() ? null : contextualValues.toSortedMap().values.first()
Is there a kotlin expression that does something similar?
I want to avoid checking for emptiness in an if block if this is possible with a oneliner
Nvm
...firstOrNull()
is a thing
lunar cypress
why isn't it a sorted map to begin with
empty flint
Also, if is an expression if you didn't know
@prisma wave How do you mean?
empty flint
oh interesting. so it's different from java there
cool
thanks
why isn't it a sorted map to begin with
@lunar cypress Right you are. Kotlin good. Blocky bad
Hm what's the best way to create a new empty map like a sorted map?
sortedMapOf<...>() ??
Or is there something like new SortedMap() ?
or SortedMap::new
or whatever
ocean quartz
You can do something like val map = sortedMapOf(Pair("c", 3), Pair("b", 2), Pair("d", 1))
ocean quartz
Copypasted it from the documentation xD
rotund egret
Ooh didnt know I could make pairs like that
prisma wave
👀
empty flint
Is there a datastructure that is an order list equivalent where each element occurs only once in the list and every element of another collection or an enum or whatever has to occur in it?
prisma wave
that is incredibly specific
LinkedHashSet will preserve ordering and doesn't allow duplicates
Not sure about the final thing
How would it work if the original collection changed?
lunar cypress
you're basically describing sets
if all elements of a set are contained within another set, you have a super/subset relation
you enforce that with checks, not by baking it into some data structure
ocean quartz
I guess this isn't too bad, for constantly spamming the command
hot hull
Very bad
empty flint
Maybe I'm being stupid again but can somebody explain what the <init> in the kotlin doc actually means?
<init>(elements: Collection<E>)
How do I actually initialize this pos class? https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-linked-hash-set/-init-.html
there dpesn't seem to be a linkedHashSetOf(...) function
hot hull
Is there a key in IJ to import everything in a class?
empty flint
This is harder than I thought
heady birch
Johnny
println!("{:06x} {:04x} {:08} {}",
track.address,
track.squawk.unwrap_or(-1),
track.call_sign.as_ref().unwrap_or(&"--".to_string()),
track.emergency_status.as_ref().unwrap_or(&EmergencyStatus::None).get_name());
Anyway to make squawk, call_sign and emergency status to give empty string
when they dont exist
Or should I just concatanate as usual
prisma wave
there dpesn't seem to be a linkedHashSetOf(...) function
Because that's what mutableSetOf is
@empty flint
or just setOf afaik
prisma wave
you sure?
empty flint
Positive
prisma wave
Last I checked setOf and mutableSetOf used LinkedHashSet
Returns a new read-only set with the given elements. Elements of the set are iterated in the order they were specified. The returned set is serializable (JVM).
?
empty flint
Idk maybe I'm confused by learning a new language rn
I might be mistaken but doesn't setOf... return a HashSet?
prisma wave
no
The function itself returns a Set
But I am confident that the implementation is LinkedHashSet
gusty fulcrum

empty flint
Hm how do I format this xD
prisma wave
liskov
please
newContextPriorities.size == ContextType.values().size pretty sure this check is unnecessary
prisma wave
lol
hot hull
L
empty flint
Nope, won't work
newContextPriorities.size == ContextType.values().sizepretty sure this check is unnecessary
@prisma wave You're right, because it's a HashSet...
So just the setter this time:
set(newContextPriorities: LinkedHashSet<ContextType>) {
if(newContextPriorities.containsAll(ContextType.values().asList())) {
contextPriorities = newContextPriorities
} else {
throw IllegalArgumentException("New context priorities failed to meet criteria. The new set has to contain each context type exactly once.")
}
}
Declaring as LinkedHashSet is kinda ew
empty flint
Yes
prisma wave
is ContextType an enum?
empty flint
Yes
prisma wave
hmm
empty flint
I'm not sure how else to do it
I could give the enums some values that indicate the order
but then they would be fixed
and couldn't be changed anymore
So nothing cleaner then? That setter definition is fugly af
prisma wave
it's not great
empty flint
I mean I guess I could do away with the else, negate the if and put the throw inside and the assignment outside
set(newContextPriorities: LinkedHashSet<ContextType>) {
if(!newContextPriorities.containsAll(ContextType.values().asList())) {
throw IllegalArgumentException("New context priorities failed to meet criteria. The new set has to contain each context type exactly once.")
}
contextPriorities = newContextPriorities
}
pretty sure you should use
field = newContextPriorities
@prisma wave I am
prisma wave
contextPriorities = newContextPriorities ?
empty flint
ye
prisma wave
that's different
empty flint
then I didn't understand what you mean
pretty sure you should use
field = newContextPriorities

class Context private constructor(val id: String, val type: ContextType)
prisma wave
better than java
hot hull
Yes, every time.

Welcome to the circlejerk
lavish notch
Am I missing something?
String name = Bukkit.getOfflinePlayer(f.getKey()).getName() || "Unkown";
why have you got the or operator there?
lavish notch
I'm wanting "Unknown" to be returned if Bukkit.getOfflinePlayer(f.getKey()).getName() is null
lavish notch
buuuurrrr
errant geyser
val name = Bukkit.getOfflinePlayer(f.key).name ?: "Unknown"``` in kotlin, come over to us MolloyYou can do
Bukkit.getOfflinePlayer(f.getKey()).getName() != null ? Bukkit.getOfflinePlayer(f.getKey()).getName() : "Unknown"
or save Bukkit.getOfflinePlayer(f.getKey()).getName() in a variable and do the above thing with the variable
prisma wave
uh no you can't
empty flint
Or switch to Kotlin. I'm slowly starting to believe
lavish notch
@prisma wave If you teach me - sure 😛
empty flint
uh no you can't
@prisma wave Sure you can
lavish notch
Teach me the fundamentals, and get my kick started.
prisma wave
@empty flint you edited it, that's cheating
@lavish notch val a = 3 = final int a = 3;
that's all you need to start
a lot is similar to Java
the kotlin docs are really good
any questions ask me and I'll write a paragraph or something

@empty flint you edited it, that's cheating
@prisma wave It's called delayed compilation

What's the most efficient way to create a leaderboard?
ConfigurationSection cf = main.getplayerData();
cf.getValues(false)
.entrySet()
.stream()
.sorted((a1, a2) -> {
int points1 = (int) a1.getValue();
int points2 = (int) a2.getValue();
return points2 - points1;
})
.limit(3) // Limit the number of 'results'
.forEach(f -> {
int points = (int) f.getValue();
System.out.println(f.getKey() + " " + points);
String name = Bukkit.getOfflinePlayer(f.getKey()).getName() != null ? Bukkit.getOfflinePlayer(f.getKey()).getName() : "Unknown";
p.sendMessage(name + " " + points);
});
I have that - but it lags the server
empty flint
it won't do much for performance but I'm fairly sure you can prettify the sort lambda to ((a1, a2) -> a1.getValue().compareTo(a2.getValue())) or something of the sorts. It's definitely a one-liner.
In the forEach lambda, try to remove the second bukkit offline player call like so:
.forEach(f -> {
int points = (int) f.getValue();
System.out.println(f.getKey() + " " + points);
String name = Bukkit.getOfflinePlayer(f.getKey()).getName();
p.sendMessage((name != null ? name : "Unknown") + " " + points);
}
Getting Player or OfflinePlayer by name is deprecated. You're supposed to get them via UUID
The thing is you can't really get the UUID if the player is offline 😛
There is a trick tho
prisma wave
another good spigot api design
errant geyser
You could get the UUID from name via a Mojang API call, but thats prolly slower than just getting by name in the first place
hot hull
Anyone else have that frustration when a plugin is like .3 over the discord upload limit
lavish notch
Nope
prisma wave
You could get the UUID from name via a Mojang API call, but thats prolly slower than just getting by name in the first place
that's what getOfflinePlayer does behind the scenes iirc
just with caching

@errant geyser I think that's exactly what I was doing
Anyone else have that frustration when a plugin is like .3 over the discord upload limit
@hot hull Why would you upload a plugin to Discord?
errant geyser
to send it to whichever kiddo wants it
hot hull
Why would you upload it to GH or some shit when it's gonna be used by a single person?
empty flint
Hm should I go with the == nullcheck or with ===?
if(worldUuid != null && network == null && rank == null) or if(worldUuid !== null && network === null && rank === null) ?
hot hull
==
lavish notch
@empty flint so can I fetch a username faster with getOfflinePlayers with a uuid?
or does it not return UUIDs?
lavish notch
returns this currently
OfflinePlayer[] players = Bukkit.getOfflinePlayers();
p.sendMessage(String.valueOf(players));
String.join(", ", players)
lavish notch
wat
empty flint
@lavish notch here's my piece of code:
https://hastebin.com/usuyefoyoq.cs
hot hull
replace String.valueOf(players) with that
lavish notch
Cannot resolve method 'join(java.lang.String, org.bukkit.OfflinePlayer[])'
hot hull
What string are you importing?
lavish notch
OfflinePlayer[] players = Bukkit.getOfflinePlayers();
hot hull
Some wack thing
empty flint
You can also do players.stream().collect(Collectors.joining(", "))
hot hull
ew streams
lavish notch
So what exactly does getOfflinePlayers return?
hot hull
final List<OfflinePlayer> playerList = Arrays.asList(Bukkit.getServer().getOfflinePlayers());
String result;
for (int i = 0; i < playerList.length; i++) {
if (i == playerList.length -1) {
result = result + player.getName() + ".";
continue;
}
result = result + player.getName() + ", ";
}
boom
It returns an array Mackenzie
empty flint
final List<OfflinePlayer> playerList = Arrays.asList(Bukkit.getServer().getOfflinePlayers());
String result;
for (int i = 0; i < playerList.length; i++) {
if (i == playerList.length -1) {
result = result + player.getName() + ".";
continue;
}
result = result + player.getName() + ", ";
}
@hot hull I just vomited a little in my mouth
hot hull
That was the point
lavish notch
There isn't a more simpler and, less taxing way?
hot hull
Not really taxing
lavish notch
fucking hell
hot hull
It's not gonna affect performance at all
surreal quarry
to make it simpler just make it a method and never look at it again
hot hull
Or use kotlin, <insert code here @prisma wave>
prisma wave
kotlin?!?!!?
surreal quarry
kotlin good

@lavish notch I really think that String.join(...) is the simplest thing ^^ https://www.geeksforgeeks.org/java-string-join-examples/

@versed ridge Why would you even...?

making a plugin for someone that's on 1.8

ah yes, good idea
hot hull
Not gonna lie, it's almost impossible finding a commission which isn't 1.8 these days
prisma wave
very sad
frail glade
Just need to know where to look.
hot hull
Nah Glare, for you it might be easy since people throw them at you, and wouldn't consider having it public otherwise
empty flint
Ah you're doing commissions. Got it. I was just about to say I would not develop on 1.8 for free 😄
hot hull
Not like I'm complaining, I've had constant commissions for the past 2-3 months so
frail glade
Wouldn't consider having it public otherwise
Wdym?
hot hull
ie. request-paid, most are 1.8 ones, I've had some people dm me asking for a non 1.8 commission, which they didn't consider putting in there, as an example
frail glade
Ohhh, I get what you mean.
hot hull
You famous
frail glade
I often do try to pass on commissions to other people that I don't have time for. If I know someone is looking, I will consider them to pass it on to.

it can, but it will never be

Avoid NPE, don't cause them.

Bukkit.getOfflinePlayers()
.filterNotNull()

still better than what you had initially 👀

how do people use abstract classes for their plugin api?

I remember seeing this api who had no return of any methods but they worked
abstract / interface class
prisma wave
you return upon preconditions

FAQ Answer:
empty flint
umm this is flattened already
steel heart
its good to think that you should make your api based on interfaces
and well interfaces is mostly aimed to determine behaviour
hot hull
Imagine using else, ew
steel heart
well I've seen worse
empty flint
I mean, in this case I can't avoid it I don't think
there is one else in there
everything else is a guard clause
distant sun
@steel heart ok but I still dont know how it works xd
empty flint
I would love if there was some sort of switch or when for conditions with multiple conditionals and their combinations
Like write down all the permutations and just list all the results
distant sun
do you do something like public interface API, public class APIImplementation implement API and API api = new APIImplementation();?
empty flint
fuck off with that if if if else else else shit already
distant sun
I assume this way you can have a public api for premium plugins?
by providing only the interfaces
empty flint
yeah ignore that then ig
@steel heart It's necessary sometimes...
actually
I have an idea
steel heart
I mean a generally case is to not expose anything in the api itself as it should only define behaviour. Gaby but I mean you don't always have to follow it just like I don't follow solid.
I mean there's a lot of explanation out there but its most likely because for instance the end user who uses the api shouldn't really know how things are done and they don't really have to care anyways. They only need to make things for themselves. Trying to modify it such as implementing it could break the behaviour.
distant sun
I assume I can make them package private
steel heart
which one?
distant sun
Trying to modify it such as implementing it could break the behaviour.
Like the API interface
or it doesn't work for implement but only for creating an instance?
steel heart
I mean implement or extend it generally. Because your application that implements them should handle that part and for instance if the end user would extend the interface Shoe, that wouldn't necessarily break anything although it can cause weird behaviour.
There's also a lot of apis which has some implementing classes that might be handling security and algorithms which the end user most likely shouldn't be able to access.

condition permutations
I'm gonna use it...
I just wish there was a cleaner way to indicate the result of the condition instead of as a string with T and F. Maybe numbers with 1 and 0 but that's not clear enough
Kotlin is fun dude
I wish I knew about it sooner
empty flint
idk if Predicate<T> is useful
@steel heart in this case? I don't think it makes sense in this case
is that a class?
there is a BitSet in Kotlin tho
prisma wave
@steel heart it's not
empty flint
its a thing u do with raw bytes
@silk jewel Oh no I know what a bitmask usually is, I just thought you meant more by it
Idk how to compare a BitSet in the when body though
What do I compare it to?
prisma wave
@empty flint any reason you can't just use a boolean?
empty flint
@empty flint any reason you can't just use a boolean?
@prisma wave Yes. There's 3 of them.
So one would be 2 too little
prisma wave
so 3 potential states?
empty flint
and all their permutations, yes
prisma wave
oh and you want that expressed in a single class
steel heart
HexaPredicate
empty flint
that's 2^3 potential states.
empty flint
I just want
if(rank != null) { if(network != null) { if(worldUuid != null) { return ContextType.RANK_IN_NETWORK_ON_WORLD } return ContextType.RANK_IN_NETWORK } return ContextType.RANK } else if(network != null) { if(worldUuid != null) { return ContextType.NETWORK_ON_WORLD } return ContextType.NETWORK } return ContextType.GLOBAL
@empty flint this to be not so fugly to look at and maintain
I have basically 3 variables that can be null or not
and depending on their combination I want different things to happen

also kotlin fun conditionPermutations(vararg conditions: Boolean): String { return conditions.joinToString(separator = "") { if(it) "T" else "F" } }
use when perhaps?

@empty flint declarative is telling the computer what to do (eglistOf(1, 2, 3).map { it + 1 }.sum()), imperative is telling the program how to do it (eg a for loop creating a new list manually

when doesn't need a variable
@prisma wave Hm does when hit on the first condition that is met?
onyx loom
yes
prisma wave
val list = listOf(1, 2, 3)
val other = ArrayList()

other.add(element + 1)

var sum = 0
for (element in other) {
sum += element

return sum
this would be declarative
and yes
the first condition, then it stops

@prisma wave Is there a shorthand notation for == null and != null?
