[solid lion]

so i would "get" the item and then check the radius of said item for entities then do damage to them?

[summer scroll]

Yes

[solid lion]

okay ill try that out thank you

discord:
  - tellraw @a {"text":"https://discord.gg/spigotmc","underlined":true,"color":"blue",clickEvent:{action:open_url,value:"https://discord.gg/spigotmc"}}

YML parser has no problem with this, how do I go about this?

https://gyazo.com/5005432a65539beab6328f4894407cf5

Here's the error I get ^

https://gyazo.com/36353e6009d73f57c9002ca9b2a40e9d

wait

look at that screenshot instead

"invalid chtat component"

use json reader

look at the last link I sent

[neon minnow]

Im a bit confused, I used thread.sleep and it crashed my server, do i use async on that part where it is doing thread.sleep then? Im making a cooldown bar like this

::::::::::::::::::::::::::::::::::::.......

But when its executed because of thread.sleep it crashes server, so do i just put this into async? Will the bar still work after that ? Do i use bukkit scheduler or

[sullen marlin]

Do i use bukkit scheduler or

yes

[stray crescent]

ok got it to work

how do I give permission to an alias?

[sullen marlin]

the permission will be the same as the main command

[neon minnow]

hi md5 🙂

[stray crescent]

nooo won't work

must be discord.* then

cause i tried "discord"

maybe i do "discord.*"

[sullen marlin]

no

it would literally be minecraft.command.tellraw

aliases dont have permissions

they just execute the command

[stray crescent]

but i have it in a /discord command?

[sullen marlin]

commands.yml really isnt good, but the essentials echo command is sometimes used

its an alias

all an alias does is execute the commands you listed

if you want something more advanced you need a plugin

there's like 10000 custom command plugins

https://www.spigotmc.org/resources/zdiscord-a-simple-discord-command.63241/

top result on google

[stray crescent]

so i cant just have a default minecraft perm that allows de-opped to do all alias commands?

[sullen marlin]

ALIASES ARE NOT COMMANDS

[stray crescent]

Feels really trashy to add a whole plugin for 1 command

[sullen marlin]

well use a plugin that allows you to add 1000 commands 😉

[stray crescent]

I know but the fact that I can do /discord as an OP but not as a deop tells me that there's a built in permission

[sullen marlin]

the permission is the tellraw permission

because aliases just execute the commands you listed

[stray crescent]

so if they have that permission they cal also do /tellraw in chat right?

can*

[sullen marlin]

yes

[stray crescent]

alr just send me the commands plugin instead pretty please

[sullen marlin]

people will be happy they were able to help

[stray crescent]

Plugin to have a broadcast every 10 min?

[summer scroll]

bump

[stray crescent]

Plugin to have a broadcast every 10 min?

[sterile token]

Hey

[sterile token]

Are you cooding your own plugin?

[sterile token]

And if you are asking how to code your plugin for brocasting. I would recommend using timestamps with a runnable

[stray crescent]

nono just if there's a plugin for it

[sterile token]

That #help-server*

[stray crescent]

cant chat in there

[sterile token]

Try verifying your account

[worldly ingot]

are you writing in python? lol

[neon minnow]

fixed

[neon minnow]

Kotlin

[mortal hare]

I was thinking

is returning new completablefuture object as a callback to the bukkit runnable

bad if im using bukkit runnables, or is it ok

i don't have thread pool, and i don't want to execute my code in fjp so im using bukkit runnables

[worldly ingot]

You can make use of a BukkitRunnable to handle your CompletableFutures, yeah, that's fine

[lavish hemlock]

Out of curiosity: what does the scheduler do that the concurrency API doesn't?

[lost matrix]

You can actually call a method sync on the main thread form within a CF

[worldly ingot]

You could Thread#sleep() to handle your futures if you really wanted to lol

Operates based on ticks, Maow

Plugin association of tasks as well

[lavish hemlock]

API or implementation difference?

[mortal hare]

yes but i need to return it as a value from a function

im returning CompletableFuture<Boolean> for later handling

[mortal hare]

internally its just probably a wrapper around ExecutorService

[lavish hemlock]

Well, that'd be the reasonable conclusion.

But CraftBukkit works in strange ways.

[lost matrix]

  public CompletableFuture<ItemStack> getPlayerItemAsync(JavaPlugin plugin, UUID playerID) {
    return CompletableFuture.supplyAsync(() -> {
      try {
        return Bukkit.getScheduler().callSyncMethod(plugin, () -> this.getPlayerItem(playerID)).get();
      } catch (InterruptedException | ExecutionException e) {
        return null;
      }
    });
  }

  public ItemStack getPlayerItem(UUID playerID) {
    Player player = Bukkit.getPlayer(playerID);
    return player == null ? null : player.getInventory().getItemInMainHand();
  }

Example

[mortal hare]

    private final ThreadPoolExecutor executor = new ThreadPoolExecutor(
            4, Integer.MAX_VALUE,30L, TimeUnit.SECONDS, new SynchronousQueue<>(),
            new ThreadFactoryBuilder().setNameFormat("Craft Scheduler Thread - %1$d").setUncaughtExceptionHandler(new net.minecraft.DefaultUncaughtExceptionHandlerWithName(net.minecraft.server.MinecraftServer.LOGGER)).build()); // Paper

it uses ThreadPoolExecutor internally

it constructs threadpool manually

although that's paper

i don't know spigot

[mortal hare]

i don't want to use CompletableFuture with FJP, due to that i have blocking IO operations

it reduces your parallelism

[lost matrix]

What is FJP?

[mortal hare]

ForkJoinPool

[lost matrix]

Ah i see. Then just supply a single thread executor.

[mortal hare]

i have no idea how to manage an executor in my case

i need to shutdown somehow

whenever its not used

[lost matrix]

Why? Thats not something you should care about. Let java handle when to put threads to sleep.

[mortal hare]

you need to shutdown your executors

[lost matrix]

You can do that when the server stops. Just create an executor when it starts with the desired amount of threads. Then onDisable flush it in a blocking fashion.

[mortal hare]

and how would i encapsulate the thread executor

[lost matrix]

You dont really need to. Just create an instance and use it where its needed.

[mortal hare]

so you're saying that i should pass it as an argument

[lost matrix]

If you really want to encapsulate it:

public class SingletonThreadPool {

  private static final ExecutorService EXECUTOR = Executors.newSingleThreadExecutor();

  public static <T> T use(Function<ExecutorService, T> function) {
    return function.apply(EXECUTOR);
  }

}

usage

    CompletableFuture<Integer> cf = SingletonThreadPool.use(executor -> CompletableFuture.supplyAsync(() -> 10, executor));

[neon minnow]

How can I turn a string into an enum of sound

thanks

(playsound)

[lost matrix]

Enum#valueOf(String)

[mortal hare]

Enum.valueOf()?

[neon minnow]

Does not exist in kotlin

[mortal hare]

i don't know kotlin

[neon minnow]

lol

[lavish hemlock]

Uhh you should be able to use valueOf

Are you trying it on Enum or your actual enum type?

[neon minnow]

Unresolved Reference

[lavish hemlock]

Because it doesn't exist on Enum

[neon minnow]

im trying it in

playsound

public static final Sound GLASS
// Enum constant ordinal: 22

[lavish hemlock]

Sooo Sound.valueOf(args[0])?

[neon minnow]

Thanks that worked

Sorry im still learning

[lavish hemlock]

I mean it's the same as Java's but yeah

I don't know why Kotlin doesn't have Enum.valueOf though

[mortal hare]

ok, but why singleThreadExecutor for io operations, wouldn't it be faster if i used couple threads instead

Even if you parallelize with multiple threads...IO to a single physical disk is intrinsically a serialized operation. Each thread would have to block, waiting for its chance to get access to the disk. In this case, multiple threads are probably useless...and may even lead to contention problems.

answered myself

im saving files to hard drive

so yeah

[neon minnow]

Do actionbars,tablistheaders,footers and title sending have an api in 1.18

[young knoll]

Yes yes yes and yes

[quaint mantle]

1.8 cringe

[sullen marlin]

Lol

[lavish hemlock]

Meh

I stopped caring about the 1.8 debate

Same shit, different day as my dad would say

[maiden thicket]

md5 :yooo:

[sullen marlin]

hi

[mortal hare]

is this ok

static getter for singlethreaded executor

[drowsy helm]

whats the usecase

[mortal hare]

for async IO operations

without depending on the tickrate and the plugin's instance

[elfin atlas]

He question is there a way to check from a list of locations what is the nearest from the player location and teleport them then there

[eternal night]

I mean, just a plain for loop would do

[mortal hare]

vector distance, but i bet there's a method for that

[eternal night]

use distanceSquared for this ^

[elfin atlas]

Okay

[eternal night]

final List<Location> locations = ...;
final Location playerLocation = ...;
Collections.min(locations, Comparator.comparing(l -> l.distanceSquared(playerLocation)));

[neon minnow]

I was thinking about this but what is a very simple method to do inventory pages? What would be the code behind it logically? Im not asking for spoonfeeding code, im just really wondering like -- what would it look like? if anyone can briefly write some pseudocode

[lost matrix]

There are two ways.

1. Having multiple inventory instances encapsulated in a wrapping class that handles the switching between them.
2. Having a single inventory that gets re-populated if you switch to another page.

So either a wrapping class with something like a List<GUIInventory> or one GUIInventory that can be updated with several page contents.

[neon minnow]

i unblocked you because you are being nice now

[lavish hemlock]

Really just depends on your abstractions

[lost matrix]

You can also have a LinkedList approach where each GUIInventory holds a reference to the next and to the previous one

[neon minnow]

Oh

Well i was thinking of something like getting the array of the data and just making the inventory every time the user flips the page and saves the number of the page so then it can remove X amount from array something like that

[lavish hemlock]

Hard to maintain, not a great idea.

[neon minnow]

and just calculating things if more pages are needed etc

[lost matrix]

Yeah you can have a single context and compute the amount of pages you need to display that content + the offset for each page

[rough drift]

So one of my plugin's files is taking up alot, alot of storage (for ex someone sent a ss of 789MB of data), and the format is like so

uuid
value
uuid
value

any better alternative? (this has to be loaded so i can check specific values for specific players, meaning 789MB won't cut it)

[lavish hemlock]

What file format are you using?

Like

JSON, YAML, etc.?

[neon minnow]

dont you have a db

[rough drift]

custom, i put it right here

[lavish hemlock]

No that's your structure

[rough drift]

its

uuid
value

[neon minnow]

what file

u storing in

and where you storing

why cant u use db

[rough drift]

oh, no ext

[lavish hemlock]

Oh so it's just line-by-line then?

[rough drift]

yes

[lost matrix]

This sounds like you might have a ton of duplicates.
Analyse the File and check for duplicated IDs.

[lavish hemlock]

Use DataOutputStream/DataInputStream or SQL

[rough drift]

nope, it only allows for one key to exist at any given time

with a single value

[lavish hemlock]

Storing it as binary would reduce that size by a lot

[lost matrix]

How do you assert that?

[lavish hemlock]

Probably via Map

[rough drift]

.

[lavish hemlock]

Map uses a Set for keys

Meaning there can be no duplicates

[lost matrix]

Other way around. A HashSet uses a backing HashMap for storage.

[lavish hemlock]

I meant keySet

[rough drift]

i mean if there was a builtin db i'd use it (one that people don't have to setup, most people using my plugin struggle editing the config lol)

[lost matrix]

Do you need all data to be loaded at all times?

[lavish hemlock]

Well a lot of people already have DBs

[rough drift]

Yes

it handles who is in the game and who is off the game

[lost matrix]

But 800mb can easily be couple hundred mb in memory...

[rough drift]

however it also stores some extra data

[rough drift]

yes

i know

[lavish hemlock]

Why are you storing this persistently?

[rough drift]

i might use this

[lost matrix]

Then you should re-design your data storage

[rough drift]

because it... has to be stored persistently

its not a round game

it just affects the world

[lavish hemlock]

Yeah but every time the server shuts down, you essentially invalidate the "is player online" data.

[rough drift]

wdym

[lost matrix]

I dont quite understand this... Everyone that isnt online is just offline. What do you need the offline data for all the time?

[lavish hemlock]

That is also true ^

[rough drift]

no no no

its like

if you are off, you can't join the server anymore, thats what i was talking about

its like an elimination system

[lavish hemlock]

So, a ban?

Oh I see

Okay so, then you don't need to store if a player is "on"

[rough drift]

nope

i aint doing that

[lost matrix]

But then why dont you load player specific data when a player tries to join?

[rough drift]

you.... make a very valid point

[neon minnow]

why not

[rough drift]

not storing on players

i hadn't tought of that

so you mean like

[lavish hemlock]

I mean all you really need to do is just store a list of UUIDs lol

[rough drift]

uuidofplayer (file)
data (in the file)

[rough drift]

i also store a tiny amount extra data needed

so yeah

[lost matrix]

AsyncPlayerPreLoginEvent is async and you can block the player there while you load his data.
Then one file per player would be better.
Just <UUID>.txt
storing all his content. This way you can load <UUID>.txt when the player joins because you will
have his uuid and therefor his file name.

[rough drift]

good point

ill do that

thanks :D

[lavish hemlock]

I'd also personally recommend using data output/input streams due to binary being smaller and faster.

[rough drift]

oh yeah

[lost matrix]

But then he would need to encode everything in binary... and that might be a LOT of work.

[lavish hemlock]

It's not :p

[rough drift]

DataInputStream/DataOutputStreams do that

[lavish hemlock]

As he said it's only "a tiny amount of extra data"

And those streams provide a fuck ton of great utils

That make it really easy to encode/decode stuff.

[lost matrix]

How would you store a List<String> for example in binary?

[lavish hemlock]

<size of list> <string size> <string contents> <string size> <string contents>

Then you just read the list size, and iterate till you reach the end.

[lost matrix]

Yeah. And the you need a bytebuffer and know the size of each character. And the encoding and so on.

[lavish hemlock]

Nope

writeUTF/readUTF

Just store it as Java's modified UTF-8

And the size of a character in that format is always 1 byte iirc

(even though a char is 2 bytes? wtf Java?)

Legit I can write an implementation rn off the top of my head

try (DataInputStream src = ...) {
    final int size = src.readInt();
    final String[] strings = new String[size];
    for (int i = 0; i < size; i++ {
        strings[i] = src.readUTF();
    }
}

Done

[lost matrix]

I doubt that this is really beneficial to be honest. Json is way less error prone and the overhead is acceptable because all IO should be done async regardless.
And the user wont notice a difference between waiting 5ms or 30ms in login.

[lavish hemlock]

The speed isn't the concern it's the size

[rough drift]

^

i should also use a inflator/deflator stream wrapping the data streams

should also provide a tiny boost

[lavish hemlock]

You'd wanna wrap the data streams around the flators

[rough drift]

oh yeah

wrong order

[lost matrix]

Sacrificing stability, readability and maintainability for size does not sound like a good idea to me.
I would rather try another approach instead of hammering a 800mb blob into a smaller size.

[lavish hemlock]

It's still stable, readable, and maintainable. What are you on about?

[lost matrix]

Like having a <UUID>.json file for each user and only load data when its needed.

[rough drift]

this, its really easy to modify this

and really easy to read

[lavish hemlock]

If you need stability between changing the format, JSON isn't going to help you. Add a fucking versioning byte.

e.g. 0 = version 1, 1 = version 2 (new and improved!)

and so on

I'd argue it's readable due to the fact it's more readable than mainly encoding/decoding it I've done this before

Instead of using a lot of bit magic, you're just working with method calls

[lost matrix]

Binary data is not readable. And its for sure not easily maintainable.
Gson will save me hours and hours of development time while someone
dabbling in binary will have to implement custom serializations for each new
type of data.

[lavish hemlock]

Theoretically, you don't need to implement custom serializers/deserializers.

I wrote a library that can generate them automatically, and its default implementation uses data input/output.

Is that stable? Fuck no.

[lost matrix]

Ive come to the conclusion that binary data is not worth it unless minimal size is an absolutely crucial requirement.
Which is rarely the case.

[vivid cave]

https://i.imgur.com/LJJcqqX.png what kind of delay are we talking about?

• 1 tick because we need to make the PlayerJoinEvent finished triggering
• an arbitrary value, which may vary based on the server performance
• an arbitrary value, which may vary based on the player connection

[lavish hemlock]

But it's still an example of how easy it is for someone to do the same thing.

[lavish hemlock]

Binary data is readable when you're the one who wrote it.

It's easier to analyze a format you made because you know the patterns.

I can't remember an entire class file off the top of my head but I can remember a data file I wrote in binary.

[lost matrix]

Its probably a fixed amount of ticks. Try it one tick later and see what happens.

[lost matrix]

And json is standardized so everyone knows the pattern... not a good argument

[vivid cave]

alr thanks for your input buddy! i'll tell you

[lavish hemlock]

Why should people need to read my cached data files?

Either they're a contributor, in which case they can read the code, or they're just a curious server owner, who I'm not trying to appeal to.

"But ma bugtesting" - Then they can file an issue report so I can analyze it for them.

Also you could easily maintain binary given the proper abstractions.

[lost matrix]

Make one mistake when implementing binary serialization -> might corrupt everything without any chance of recovery.

[lavish hemlock]

I wrote said abstractions in like, less than 3 hours.

[lavish hemlock]

Well that's why you implement testing first.

Either through manual testing or unit testing.

[lost matrix]

So you can just throw any class at your serializer and it will scan all fields via reflections and has a ton of serializations for all kinds of collections and data structures?

And recursive serialization.

[lavish hemlock]

No I was referring to the actual serializer/deserializer bit, not scanning and common implementations.

But, yes, I have a framework that does that.

Even then, I'd argue that automatic serialization like that leaves you with a lot less control.

[lost matrix]

Alright you do you... I clearly have a different opinion on that topic. Wont even get started with data migration. Storing all that in a sql or nosql db would be fun for sure.

[lavish hemlock]

A problem I have with Gson is that you have to implement manual serialization just to have a better API in some cases.

You ever read a version manifest? The thing is filled with garbage that is just better to filter out.

(But, then you need to implement manual serialization, which is a nightmare with Gson)

(I know this because I had to write abstractions just to work with it)

[lost matrix]

Huh? how is that a nightmare? Its object oriented and way better than every other serialization library in that regard.
And you dont have to implement custom serializers you can simply define rules for your Gson instance on what needs
serialization and what doesnt-

[lavish hemlock]

Nullability.

And the amount of chained method calls.

[lost matrix]

Dont just throw keywords at me... Nullability is not a problem exclusive to Gson. And i dont even know what you mean my "chained method calls".

[lavish hemlock]

Meh

[rough drift]

imma still not go with json

i deeply not like json when there are better alternatives

[lost matrix]

  @Override
  public JsonElement serialize(PlaceholderExpression src, Type typeOfSrc, JsonSerializationContext context) {
    JsonObject jsonObject = new JsonObject();
    jsonObject.addProperty("original", src.getOriginal());
    jsonObject.add("icon", context.serialize(src.getIcon()));
    return jsonObject;
  }

Thats as complex as it gets with custom serialization when using Gson.

[lavish hemlock]

Hell yeah, resist the public mentality @rough drift. You deserve a cookie 🍪

[rough drift]

xD

no but like seriusly

i don't wanna go like

[opal juniper]

i love json!

it’s so simple

[lavish hemlock]

Try it the other way around now

[rough drift]

public class MyPlayerDataFile {
  private String abc;

  public String getAbc() {
    return abc;
  }
}

Gson gson = new Gson();
gson.load(string, MyPlayerDataFile.class);
```or smt like that

thats just bad design

[lost matrix]

  @Override
  public PlaceholderExpression deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
    JsonObject jsonObject = json.getAsJsonObject();
    String original = jsonObject.get("original").getAsString();
    ItemStack icon = context.deserialize(jsonObject.get("icon"), ItemStack.class);
    PlaceholderExpression condition = new PlaceholderExpression(original);
    condition.setIcon(icon);
    return condition;
  }

Simple...

[lavish hemlock]

What if one of those are null?

Hell, what if all of them have the potential to be null?

We're talking theoretical situations here, not your actual use-case.

[rough drift]

meanwhile, data output streams:

out.writeUTF(abc);

in.readUTF();

[lavish hemlock]

pfff

[rough drift]

much easier to use those ngl

[lost matrix]

Then they are just null... which means the constructor will be called with null values. Which will be a problem with every de-serialisation method.

[lavish hemlock]

Sure but it's still a fuckin' nightmare in Gson

Mainly since you work with a lot of optional data at once

[lost matrix]

The code ive sent is null safe. Gson handles all of that.

[rough drift]

imagine the json structure changes, you have to change the class you load to and every class that uses it

[lavish hemlock]

Anyway I don't feel like arguing anymore since it's literally 4 AM for me

And it's my fucking birthday

Aaaand I'm not in a great mood

[rough drift]

oh happy bday

[lost matrix]

Oh happy birthday

[rough drift]

gn maow :D

[lost matrix]

I also got mine in a month. I just hope nobody bothers me XD

[rough drift]

(i guess its gn since 4am)

[lavish hemlock]

Probably only sleepin' at like 5-6 AM

[rough drift]

ohk

[lavish hemlock]

[rough drift]

private fun getOutputStream(file: String): DataOutputStream {

[neon minnow]

How do i use bukkit scheduler because i try to use it but my server is still lagging.....

I need to use thread.sleep

[rough drift]

wdym

[lavish hemlock]

Oh shit you use Kotlin?

Dang I like you

You are based like me

[rough drift]

yeah kotlin is good

[lavish hemlock]

Kotlin is fantastic

[neon minnow]

https://ibb.co/44sZWw5

[rough drift]

somethings i prefer java for some stuff (like api's that don't have a kotlin impl)

[lavish hemlock]

I think most of Kotlin's APIs are better but ye

You seen Clikt yet? Compare that shit to JCommander lmao

[rough drift]

nope but i gotta check it out

HOLY

its so good

[lavish hemlock]

It is

It really is

It covers like all possible use-cases too

[neon minnow]

Yeah i use kotlin too...

[lavish hemlock]

I don't code in Kotlin very often but it does consistently make me happy.

I'm just one of those people who is stuck with Java out of the comfort of already knowing it :/

[neon minnow]

How do I use bukkit scheduler (https://ibb.co/44sZWw5) because my server still lags when I do

            override fun run() {

                for (i in 1..100) {
                    myshitFunction()
                    Thread.sleep(cooldownTime.toLong())
                }
                for (i in 4 downTo 1) {
                    myshitFunction()
                    Thread.sleep(230)
                }
            }

        }.runTask(Instance.plugin)

[rough drift]

its like kambrik but for CLI (https://kambrik.ejekta.io/)

[rough drift]

Bukkit.getScheduler().scheduleSyncRepeatingTask or smt

[neon minnow]

i dont understand...

[chrome beacon]

Never use Thread.sleep when working with Spigot

[rough drift]

Bukkit.getScheduler().scheduleSyncRepeatingTask(yourPluginInstance, runnable, delay, interval) smt like that

[lavish hemlock]

Never use Thread.sleep in general, it's usually not a good idea :p

[chrome beacon]

A runnable won't magically fix the fact that you're pausing the server thread

[rough drift]

i mean, it can be helpful if you have no other option

tho generally its so slim, don't use it

[neon minnow]

Help me understand how to use cooldowns and other things like that I want to implement

[rough drift]

why not learn the bukkit api first-

[lavish hemlock]

?learnbukkit

lol

[rough drift]

?learnbukkitbeforemakingpluginsplease

aw i tought it was a command

Just use the BukkitScheduler like you've done above. But instead of using Thread.sleep use nested Schedulers or something like TaskChain (an additional dependency)

[lavish hemlock]

nah I meant for like

✨ dramatic effect

[rough drift]

o

[lavish hemlock]

e.g. when my boyfriend says some stupid shit and I have to take a moment to process and make fun of him

[rough drift]

lmao

[lost matrix]

Cooldowns should always be done with a timestamp.
So when a user executes and action -> you add a timestamp
When he tries it again you simply calculate the time between now and the timestamp
Eg delta is 3211ms and the cooldown would be 5s. Then you can tell him to wait around 2.7s before he can use that action again.
Dont use schedulers or threads for that.

[lavish hemlock]

That is confusing.

[neon minnow]

Im talking about a cooldown actionbar, that does a little animation like :::::::.....

[rough drift]

wouldn't it be more accurate to round to 3.2 so the player has to wait 2.8

(in the msg)

[lost matrix]

3.21 -> 2.79
If you format that using %.1f then it will be 2.7

[rough drift]

fair

[lost matrix]

Then you would still handle the cooldown with a timestamp. The only difference is that you check the stamp every N ticks. (5 should be fine)
This requires a scheduler.

[waxen barn]

Is there some easy way to store just 1 int between restarts or do I have to create a binary file for it?

[lost matrix]

Hm you could just use the PersistentDataContainer of the main world

If you really dont want to write into a file

[lavish hemlock]

The world has a PDC?

Does my computer also have a PDC?

Am...

Am I a PDC?

[waxen barn]

Oh, I didn't know that world itself has also a PersistentDataContainer, thx

[lost matrix]

Pretty new feature

Bukkit.getWorlds().get(0).getPersistentDataContainer().set(NamespacedKey.fromString("custom:version"), PersistentDataType.INTEGER, 90);

[waxen barn]

Do you know In what version it was added, because I want to know how much backwards compatible it would be?

[lost matrix]

Hm... quite recent. A workaround would be to use the PDC of a fixed chunk.
So the PDC of the chunk 0/0 at the main world. But lets see when the world got a PDC.

?stash

[undone axle]

https://hub.spigotmc.org/stash/

[eternal night]

world PDC is available on 1.18.1 only

the API was first added 3 days ago 😅

[waxen barn]

hmm, I'll probably need to use something different then xd

because I want to support more versions than just 1.18.1

[lost matrix]

So the PDC of the chunk 0/0 at the main world.
Just hack it in there

But dumping data into a binary file is really not that much effort.

[eternal night]

chunk pdcs exist since 1.16 iirc

[lost matrix]

Perfect. You wouldnt want to support anything earlier.

[waxen barn]

hmm, that's probably ok

[eternal night]

Yea, just make sure to not grab 0/0 but preferably the servers spawn chunks (which might be moved)

chunk PDC has the unfortunate issue that chunks unload and load

so if someone moves the world spawn but you grab the PDC of the chunk at 0/0 a bunch -> loading that chunk over and over

[lost matrix]

@Data
public class SomeConstants {

  @Getter
  private static final transient SomeConstants instance = loadOrCreate();
  private static final transient Gson GSON = new GsonBuilder().disableHtmlEscaping().setPrettyPrinting().create();

  private static SomeConstants loadOrCreate() {
    JavaPlugin plugin = JavaPlugin.getPlugin(SmileCore.class);
    File folder = plugin.getDataFolder();
    File file = new File(folder, "constants.json");
    if (!file.exists()) {
      return new SomeConstants();
    }
    try {
      return GSON.fromJson(Files.readString(file.toPath()), SomeConstants.class);
    } catch (IOException e) {
      e.printStackTrace();
      return new SomeConstants();
    }
  }

  private SomeConstants() {}

  private int version;
  private String info;
  private double temp;

  public void save() throws IOException {
    JavaPlugin plugin = JavaPlugin.getPlugin(SmileCore.class);
    File folder = plugin.getDataFolder();
    folder.mkdirs();
    Files.writeString(new File(folder, "constants.json").toPath(), GSON.toJson(this));
  }
  
}

    String info = SomeConstants.getInstance().getInfo();
    SomeConstants.getInstance().setInfo("New Info");

  @Override
  public void onDisable() {
    try {
      SomeConstants.getInstance().save();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

Thats all a bit hacky but at least you can add as much data into the constants class and it will always be up to date without changing anything.

[waxen barn]

hmm, isn't it better to save the data using byte streams?

[lost matrix]

Huh? Why? What do you mean by better?

[lavish hemlock]

Lmao 7smile7 is just getting his ass beat by the bytes

[lost matrix]

The user does not notice a difference between 2ms and 20ms. Its literally 1/50th of a second.

[waxen barn]

idk, I think, that it has smaller size + you don't want the user to mess with data, that aren't in config, so he won't write there something incorrectly, and json is really easy to edit

[lost matrix]

And here you can literally just add a Map<String, Integer> or even some deeply nested shit with complex classes and you dont have to change a single line of code besides adding all the data you want.

[lost matrix]

base64 encode it then. You guys with your binary data. You can do that when fiddling with optimizing pdc types but
for stuff like that you should value modularity over everything else. Coming back to bin data and changing stuff without
invalidating every data out there is just not worth anyones time.

I mean. If its literally just a single int and you are 100% certain that you wont ever have to add any other data then go ahead and write your 4 bytes into a file.

hell you can even just use the name of an empty file

[lavish hemlock]

Ooh reminds me of the folders programming lang

https://esolangs.org/wiki/Folders

Fun fact: A newer spec of it is name-agnostic.

Ah yes that's my favorite instruction

Oh ye and you can write like

some programs in it

there's no way to do file IO or UI so it's basically as useless as brainfuck

but

y'know :)

[lost matrix]

brainfuck can use IO
stdout

[lavish hemlock]

Not file IO

[lost matrix]

Sure. You can use stdout to do file IO

[wispy plume]

Hey, how can I disable switching spectator targets?
I want to allow a spectator to get into an entity, but I don't want them to switch entities without dismounting from the first one and then mounting to another.
Is there an event called when doing that, or do I have to play with packets?

[lavish hemlock]

No I'm pretty sure Brainfuck doesn't support piping or redirection or whatever the fuck

[lost matrix]

It has access to stdout. It can do anything. You could even do http requests if you wanted.

[sullen marlin]

Pretty sure theres an event

[lavish hemlock]

Can I run Brainfuck in Brainfuck?

[sullen marlin]

Might be the teleport event with teleport reason

[waxen barn]

that the reason why I asked if there isn't some better solution that creating a 4 bytes file (I solved it by writing it to the spawn chunk)

[lost matrix]

its turing complete. You can do anything. Even write an interpreter for itself.

[wispy plume]

Yep, PlayerTeleportEvent.TeleportCause.SPECTATE
Thank you!

[lavish hemlock]

Can I run Minecraft in Brainfuck?

Add a permission or a programmatical condition with your UUID or name

[sullen marlin]

Definitely permission...

[chrome beacon]

^^

[warm light]

Which is best? Oracle JDK or OpenJDK or other?

[neon minnow]

OpenJDk

[lost matrix]

I mean. If he wants it to be absolute then permissions wont cut it as everyone else with this permission or op could execute that command

[lost matrix]

Basically the same. Just different licensing.

[warm light]

No diff? like performance or etc?

[lost matrix]

Its the same jvm. No difference at all performance wise.

[lost matrix]

If you want to improve your performance you should focus on jvm arguments. Mainly for garbage collection.

Ok

also what is the spigot server maven repo

for nms

[lost matrix]

What version are you on?

[gritty urchin]

1.8.8

dont shoot me

[lost matrix]

You need to run BuildTools once for 1.8.8 to install it into your local maven repo.
Then the dependency is the same with the exception of the artifactID which is now spigot instead of spigot-api

[chrome beacon]

?bt

[undone axle]

[gritty urchin]

yeah ok

i think ill just add it to dependencies manually

[lost matrix]

You cant just manually add a maven dependency. How do you compile?

[gritty urchin]

why not

its just provided

i dont need to compile with the project?

[lost matrix]

Ok but how do you compile your jars? Do you build artifacts?

[gritty urchin]

no

build with maven

[lost matrix]

Ok and what do you mean by "manually adding" the dependency. Using mvn install:install-file?

[gritty urchin]

just adding to modules and dependencies

and setting to provided

[lost matrix]

I mean. Just run BuildTools once and add

[spare prism]

removed the async part and now it returns what I want, lmao

but I have to do it async

cause it is a db connection

how can I fix it?

[lost matrix]

You wait for the transaction to complete. Async of course. One viable tool for this are CompletableFutures.

[grim ice]

what the fuck

that's fucked up imo

[lost matrix]

Hes joking. I think its 15 or 16

[spare prism]

can u give me an example pls

[grim ice]

15 or 16 still fucked up

15 was possibly an emo kid a year ago

[lost matrix]

That because beer is a staple food here.
No hard alcohol.

[lost matrix]

Hm. Not a simple one.

Show me some code

[spare prism]

List<String> result = new ArrayList<>();
ProxyServer.getInstance().getScheduler().runAsync(Main.getInstance(), () -> {
    // db connection etc...
    result.add(resultSet.getString("test"));
});
return result;

[lost matrix]

The problem here is that the list will be empty when you return it because the database call takes a while.

[spare prism]

yeah

but how can I avoid it

I mean

to do it async

but to return a correct object

[lost matrix]

Solution: Dont return a List but return a CompletableFuture of that list.

  public CompletableFuture<List<String>> fetchData() {
    return CompletableFuture.supplyAsync(() -> this.loadData());
  }

  private List<String> loadData() {
    List<String> result = new ArrayList<>();
    // db connection etc...
    result.add(resultSet.getString("test"));
    return result;
  }

A completable future doesnt have that object right away. But it tells you that it will have that object eventually.
So you dont use the object directly but rather define actions for that object as soon as the CompletableFuture has it.

  public void tellPlayerAllBans(Player player) {
    CompletableFuture<List<String>> listFuture = this.fetchAllBannedPlayers();
    listFuture.thenAccept(list -> {
      for (String name : list) {
        player.sendMessage(name);
      }
    });
  }

  public CompletableFuture<List<String>> fetchAllBannedPlayers() {
    return CompletableFuture.supplyAsync(() -> this.loadAllBannedPlayers());
  }

  private List<String> loadAllBannedPlayers() {
    List<String> result = new ArrayList<>();
    // db connection etc...
    result.add(resultSet.getString("test"));
    return result;
  }

Compact version:

  public void tellPlayerAllBans(Player player) {
    this.fetchAllBannedPlayers().thenAccept(list -> list.forEach(player::sendMessage));
  }

  public CompletableFuture<List<String>> fetchAllBannedPlayers() {
    return CompletableFuture.supplyAsync(this::loadAllBannedPlayers);
  }

  private List<String> loadAllBannedPlayers() {
    List<String> result = new ArrayList<>();
    // db connection etc...
    result.add(resultSet.getString("test"));
    return result;
  }

CompletableFutures are really hard to understand initially. And you need to fully grasp the concept of lambdas because you will see them used a lot
in CF contexts.

[spare prism]

tysm, @lost matrix

I will try it

[spare prism]

it doesn't work either, @lost matrix

    public CompletableFuture<List<Punishment>> fetchPunishments(String key) {
        return CompletableFuture.supplyAsync(() -> this.retrievePunishments(key));
    }

if(dataManager instanceof MySQLManager) ((MySQLManager) dataManager).fetchPunishments(key).thenAccept(list -> this.punishments = list);

[blazing scarab]

Don't think about the result, think about what are you going to do with it

I'm going to initialize all my fields in the class 🙂

    @Override

        if(dataManager instanceof MySQLManager) ((MySQLManager) dataManager).fetchPunishments(key).thenAccept(list -> this.punishments = list);
        else this.punishments = dataManager.retrievePunishments(key);

it will work automatically?

[quaint mantle]

so i am trying to use this to deserialize an itemstack array in the same file as the menu class, how would i do so?

[gritty urchin]

Hey

how would I make a custom nms zombie

immune to sunlight

[young knoll]

Does it need to be NMS

[gritty urchin]

yes

I want custom entity pathfinding

and to override other default behaviour

[young knoll]

There’s probably a method that controls it

Or you can use the combust event

[gritty urchin]

I've found it

#n();

so what do i do now

[young knoll]

Well, what does the original n() do

[gritty urchin]

well its where the sunlight burning part is stored

[young knoll]

Override it

[gritty urchin]

yeah but then I have to rewrite every single method inside it

or most of them

cuz they are protected

[young knoll]

Not much you can do there

[gritty urchin]

also how do i find these methods

[bright wind]

how to write it?

[gritty urchin]

[wb, craftingi]

[bright wind]

thx

[young knoll]

Know your way around a decompiler or use remapped

[quaint mantle]

how would i make an ArrayList<ItemStack> just an ItemStack?

Get an element from it

A list is generally multiple of an object

[quaint mantle]

I'm not sure I understand. There are no blocks that clip through terrain as far as I'm aware

[quaint mantle]

there was a way to set no-clip to true before they updated Nms

that isnt a coding question

[devout sinew]

[gritty urchin]

Hey

how do I make a custom nms zombie

move to a specific location

[grim ice]

what class was it

EntityZombie right

or what class

[gritty urchin]

yeah EntityZombie

ive spawned the zombie

and overridden some default goals

[grim ice]

.getBukkitEntity() on the EntityZombie

does that exist

[gritty urchin]

yes

[grim ice]

ok

now u can .teleport()

on getBukkitEntity()

[gritty urchin]

yeah but I want it to walk

like move to another location

and turn its head also

in the direction it is facing

[grim ice]

then use pathfinder goals

I've found this but it's for 1.13.2

public void moveToLoc(Entity en, Location loc){
EntityCreature cr=((EntityCreature) ((CraftEntity) en).getHandle());
cr.getNavigation().a(loc.getX(), loc.getY(), loc.getZ(), 1);
}

or maybe its possible to make an invisible entity then make it the target of the mob

not sure if that is worth trying

[gritty urchin]

yeah that does nothing

[quaint mantle]

i have three arraylists, how would i merge them into one arraylist or something of the same purpose

public transient ArrayList<ItemStack> menuitems = new ArrayList<>();
public transient ArrayList<Integer> menupositions = new ArrayList<>();
public transient ArrayList<String> menunames = new ArrayList<>();

[gritty urchin]

I think its pathfinder goals have to defined

in its constructor

but idk how to do that

[grim ice]

found this in google tho

not sure if u wanna follow his advice

[gritty urchin]

ye but I dont think 1.8 does

1.13+

annoying

[grim ice]

make your own class

I assume you wanna make a Menu class

[hasty prawn]

I've had issues with goals and paper before, although I was using NMS

[quaint mantle]

this is in the class

i need to merge these three arrays somehow

since they output to json

[hasty prawn]

On Spigot my mob did everything right. On Paper he kinda just stood there with a blank stare 🧍‍♂️

[grim ice]

make your own class

[quaint mantle]

    @EventHandler
    public void onLeftCLick(PlayerInteractEvent e) {
            if (e.getAction() == Action.LEFT_CLICK_AIR){
                if (e.getPlayer().getInventory().getItemInMainHand().getItemMeta().getDisplayName().equalsIgnoreCase("§6Gyrokinetic Wand")){
                    new GyrokineticStorm(e.getPlayer()).play();```
How do i addnull check in this?

[grim ice]

basically make a class Menu

.getName(), .getPosition(), .getItem()

then an arraylist of that class

honestly idek what u wanna do

[grim ice]

what

anyways you shouldnt check items by names

[quaint mantle]

that was the easiest way i could find soo yeaa..

this is just to mess around with friends soo no need to make it too fancy

but i need to make a null check if held item aint null bcz if its null it spams console

[hasty prawn]

What's null

[grim ice]

then do it

[hasty prawn]

probably getItemInMainHand or getItemMeta

[grim ice]

if(item != null)

literally

llol

[grim ice]

he knows how to get that

in his code

[hasty prawn]

Or do it the other way ;)

if(item == null) return;

[grim ice]

thats what i usually do ^

[hasty prawn]

Yeah but he has to know what's going to be null

[quaint mantle]

oo thx

[hasty prawn]

If you just check a random thing that can't be null that's not very helpful

[grim ice]

he knows how to get the ite

ite

m

he did it in his code so

[hasty prawn]

Nevermind lol

[grim ice]

weird question tbh

eitherway

[quaint mantle]

i can use if(item == null) return; this right

[grim ice]

yes

[midnight shore]

Hi guys! I have a problem
Basically i want to have a variable named Health which can go up to Integer.MAX_VALUE and i want it to be my max health. But there is a catch: I don't want to have 500+ hearts. I want it to cap at 20 hearts maximum. How can i do this?

[quaint mantle]

its a very neat way ty

[grim ice]

setHealthScale() probably something with that

or you could store the health somewhere else

[tardy delta]

is streaming and filtering Bukkit.getOnlinePlayers less efficient than looping over them and checking with an if?

[midnight shore]

ty! it worked perfectly

[grim ice]

did it actually

[midnight shore]

i think yes

[quaint mantle]

i want to have these three arrays in a .json file

but since gson can't understand itemstacks, i have to deserialize menuitems seperately

so

[grim ice]

" if you have a small list; for loops perform better, if you have a huge list; a parallel stream will perform better. ... So although the difference is not that big, for loops win by pure performance. That being said; performance is not the only important metric to measure your code by"

[quaint mantle]

i cant make a class

[midnight shore]

wait, now there is another problem. my hp in general caps at 520 even if i have more than that

[grim ice]

the scale, or the actual health

[midnight shore]

the actual health

that message says that i've been healed

[grim ice]

I am not spanish or whatever that language is

either way

just make your own health system

[midnight shore]

that is my own health system

[grim ice]

although it will interfere with other plugins but whatever

[midnight shore]

and thats not spanish

[grim ice]

nah add an attribute to the Player

or

save each player health in a hashmap

[midnight shore]

never mind

i found the problem

[grim ice]

o alr

[gritty urchin]

@grim ice do u know any pathfinding libraries

for 1.8.8

[grim ice]

No

sadly

[midnight shore]

basically i wasn't setting the max health so it stayed to the one i had before testing this

[midnight shore]

Thats Italian tho

never mind

[quaint mantle]

null check is only working with items not with empty hand should i add a air check too?

[midnight shore]

The game crashed whilst unexpected error
Error: java.lang.NullPointerException: Cannot read field "A" because "☃" is null

what the hell is this

Hey
I'm trying to spawn a custom zombie using nms
it works
but the zombie just stands still
even though I haven't removed any of its goals
or targets
Is there any reason for this?
https://pastebin.com/x4bssZPW

CustomZombie.java

CustomZombie.EntityTypes.spawnEntity(zombie, new Location(p.getLocation().getWorld(), p.getLocation().getX() + 2, p.getLocation().getY(), p.getLocation().getZ()));```

where it is spawned

[mellow mesa]

Hey, I am currently having a problem many people in forums had, but I couldn't find any helpful answer. It's about world generation and how to just modify the existing world generator and not setting up a new one. In my case, I want to replace every generating block in a chunk so that every chunk consists of a random block. All the forum answers were rather confusing for me, so it would be great if someone can help me, maybe in DMs or so.

[hasty prawn]

Does it do anything if you hit it

[gritty urchin]

nope

no kb

but it takes damage

so you can kill it

been stuck on this for like 4 hours

[hasty prawn]

Hmm weird, I have no idea. If you were using 1.18 I could help you more but... 😟

[gritty urchin]

is there a lot of API change

between the two?

[hasty prawn]

Well for one, 1.18 has mojmaps so it's not obfuscated.

[gritty urchin]

ah

is there anyone here

who is good at 1.8.8 NMS?

or do you know anybody?

[hasty prawn]

Probably no one in here, afaik all the active helpers in here don't support 1.8.

Most the people asking questions are on 1.8

Or, most people who support 1.8 are asking questions, not answering them.

Generally if you're going to support 1.8 you're kinda on your own.

[young knoll]

I remember 1.8 NMS

Just like it was yesterday 7 years ago

[gritty urchin]

yeah I know it is outdated

I just want to know how to spawn a custom nms zombie

[hasty prawn]

Your best bet is to find also outdated forum threads then

[gritty urchin]

that doesn't stand still

[gritty urchin]

yeah no luck with that

[hasty prawn]

Yikes, well I'm not sure what's wrong with what you're doing tbh.

[obtuse torrent]

can i ask spigot questions here?

[vocal cloud]

I don't know can you?

[obtuse torrent]

i dont know thats why i ask

[young knoll]

Read the channel description

[obtuse torrent]

ok thanks

am trying to code in 1.8.8 i downloaded buildtools and ran it with git bash, i restarted intellij but i still cant change the version in pom

[vocal cloud]

?paste the not working pom you're trying to use

[undone axle]

https://paste.md-5.net/

[maiden thicket]

1.8 nms scares me

[obtuse torrent]

like the code?

[maiden thicket]

did u specify the version

[maiden thicket]

well yeah no one uses 1.8 anymore

no reason to

if someone uses it its "fOr pVp"

1.8 nms also is stinky

[obtuse torrent]

ok

[maiden thicket]

did u specify the version

when u ran buildtools

[obtuse torrent]

yeah

[maiden thicket]

are u using mave or gradle

[obtuse torrent]

maven

[maiden thicket]

show me ur dependency

[obtuse torrent]

why?

[maiden thicket]

to see if u wrote it correctly

[vocal cloud]

I love the why?

[obtuse torrent]

i used the minecraft developer plugin

in intellij

[maiden thicket]

that doesnt use nms

that uses spigot api

only

[vocal cloud]

We don't care what you used that's not what we're asking

show us the pom

[obtuse torrent]

i pasted the code in the paste.md thing

[vocal cloud]

Then you save it and send the url

[obtuse torrent]

its rn 1.12 but trying to change it to 1.8.8

https://paste.md-5.net/xeyopegize.xml

[maiden thicket]

yes so replace spigot-api w just spigot

and replace the version w 1.8.8-R0.1-SNAPSHOT

[obtuse torrent]

ok

oh that works

thanks

but its wierd in tutorials its spigot-api and it works but yeah

[maiden thicket]

spigot-api includes org.spigotmc and org.bukkit

spigot includes those w nms and craftbukkit

[obtuse torrent]

oh

[vocal cloud]

I mean 1.8.8-R0.1-SNAPSHOT works just fine for me

for spigot-api

[obtuse torrent]

do you use Minecraft developer plugin?

[vocal cloud]

Yes

[maiden thicket]

doesnt give u nms

[obtuse torrent]

wierd

[vocal cloud]

Wasn't talking NMS

[maiden thicket]

yeah i know he wanted nms tho

[vocal cloud]

1.8.8 NMS 🤢

[maiden thicket]

1.8.8 🤢

[lavish hemlock]

1.8 🤢

[maiden thicket]

old legacy versions 🤢

[obtuse torrent]

java makes me rage quit

[lavish hemlock]

Then get better, scrub

[obtuse torrent]

no

[lavish hemlock]

Fair enough

[maiden thicket]

[austere cipher]

Question, would it be possible to use packets to create "sharding", where players build in the same location, though blocks appear visible only to them (client-sided) as packets are sent to them only? Minimalizing server resource usage

[vivid cave]

is there a way to cache packets in a player? i mean
i cache the packets inside their files/memory, and then instead of keep resending the same packets in cycle, i just tell them to use packet n°3 then n°4 then n°5 then back to n°1 in a loop
its for animated stuff, no i won't be using texture packs/data packs, right now the packets are cached on the server and i keep sending them to the player in a loop, instead i thought it would be better if i send them only once and tell them "switch to this packet for this, or to that packet"

[tardy delta]

poor zombie

[gritty urchin]

is anyone here familiar with 1.8.8 NMS?

[delicate lynx]

?ask

[grim ice]

Should I learn more java that I get to a fairly advanced level or do I learn another language

the only other language I might learn is Rust

other than Rust maybe C#

[waxen plinth]

Depends on your goals

[grim ice]

make ?dataja or edit ?ask to https://dontasktoask.com/ ngl

[waxen plinth]

Rust is a very cool language and definitely worth learning if you ask me

[grim ice]

My main goal is to progress as a developer

that might be too general

[waxen plinth]

Try a new language but I think it's good to have at least one language you could consider yourself an expert in

For interviews you will usually be able to pick a language to work in

[grim ice]

how much time of experience is an expert

[waxen plinth]

Having a language you know like the back of your own hand is extremely valuable for interviews

I've been doing Java for about 8 years and I feel very confident in my skills

[grim ice]

damn 8 years

[waxen plinth]

Where the actual line of "expert" is is hard to say

[lavish hemlock]

Yeah this is possible.

[waxen plinth]

But I could write code to do most things without the help of an IDE, without looking up how to do any of it

I don't have any other language I'm that good with

So I always interview in java

And it's been really useful

[vivid cave]

caching packets into player memory?

[waxen plinth]

My friend knows a lot of languages, definitely a lot more than me, but he's not really an expert of any of them so he struggles a bit more in interviews

It's not even so much about skill as it is just familiarity

[lavish hemlock]

I guess I know his answer to "Would you rather be an expert in one language or know a bunch of languages"

[waxen plinth]

Knowing the standard library off the top of your head makes a huge difference

[waxen plinth]

You should always be a bit of both

[grim ice]

oo

[waxen plinth]

I can use a lot of languages but I'm far better with Java than any other

[grim ice]

ic

[lavish hemlock]

I am a Java expert, with a good amount of Kotlin knowledge, and I know a lot of langs but am not a big fan of/am not good at them.

[grim ice]

ok then ill focus on java

tbh i find java perfect eitherway

it might not be as fast but its fine

[waxen plinth]

I really like Java too

It's plenty fast for almost everything

[lavish hemlock]

I don't, I'm just good at it.

[grim ice]

i find java organized

[waxen plinth]

It's pretty simple, fast, has good naming conventions, streams are really nice

[grim ice]

but it's not really good to make good looking applications with though

[waxen plinth]

Rust is probably the most immaculately designed language I have ever seen but it's hard to write

[lavish hemlock]

I find the problems with Java stem from verbosity

[grim ice]

How do people make really cool looking apps btw

[waxen plinth]

I think even an expert in rust could have difficulty writing code that will compile and work the first try

[grim ice]

is there some markup language for apps or smth

[waxen plinth]

It's become a lot less verbose lately

[waxen plinth]

Fxml?

[grim ice]

otherwise how do people make cool looking apps

okay makes sense

is javafx

the only good way

to make java apps

[lavish hemlock]

Not within it's object hierarchies.

Also yeah basically "good looking" Java apps come down to:

• Requiring an extensive knowledge of Swing
• Using JavaFX

[waxen plinth]

I never really had a problem with those

You can usually keep hierarchies relatively simple

[lavish hemlock]

I mean

Not when you have 2 modules

One API and one impl

And they sorta

mirror each other

Which is a very common pattern from what I've seen :p

It's unmaintainable.

[grim ice]

Alright so uh

what do you guys think I should learn now

[waxen plinth]

I always encourage people to write a JSON parser

[grim ice]

is there a reason why json is better than YML

[waxen plinth]

It's a good intermediate project that teaches you about a lot of good concepts

[lavish hemlock]

And I mean that's not the only problem I have with Java.
You have this situation where you need a factory class because using constructors doesn't give you enough power.

But y'know a factory per class is obnoxious, so static factory methods, although not everyone agrees on using them.

[waxen plinth]

Yml is much more annoying to parse

[lavish hemlock]

(Also sometimes your factories need to store a bit of state)

[grim ice]

how is it that ba

bad

[lavish hemlock]

(And people will scream static abuse)

[grim ice]

sounds easier than parsing json

[lavish hemlock]

Uhh YML is hard to parse because YML is an obnoxiously complicated format

[grim ice]

or maybe not

[grim ice]

i find json way too unreadable tbh

just looks ugly

[lavish hemlock]

Well it's not designed to be readable

It's designed for networking

[waxen plinth]

I can express json's entire format in just 11 lines of bnf

[lavish hemlock]

Yeah lol ^

[waxen plinth]

You literally cannot represent yaml with bnf

[grim ice]

what even is bnf

[waxen plinth]

A format for describing file formats

[lavish hemlock]

Backus-Naur Form: It's a grammar that allows you to describe formats/languages.

[grim ice]

what

[lavish hemlock]

https://en.wikipedia.org/wiki/Backus–Naur_form

[waxen plinth]

It's a bit like regex but much more powerful

[lavish hemlock]

Is YAML context-sensitive?

[waxen plinth]

Yes

Because indentation is syntactic

[lavish hemlock]

Oh dear

[waxen plinth]

Yeah lol

That's why you can't bnf it

[lavish hemlock]

So yeah BNF is described as a "metasyntax"

Meaning it's syntax for describing syntaxes

[grim ice]

i dont get it kekw

[waxen plinth]

Meanwhile here's json

[lavish hemlock]

It's typically used by people designing lexers/parsers

[waxen plinth]

https://github.com/Redempt/RedLex-JSON/blob/master/res/json.bnf

[lavish hemlock]

Or also by parser generators like ANTLR

[waxen plinth]

It's 13 lines but you can easily get it to 11

[lavish hemlock]

Also JSON is just faster to parse

Also to write

[waxen plinth]

Yeah just look at simdjson

JSON is honestly great

[grim ice]

oh so do parsers use bnf

[waxen plinth]

It's really simple and gets the job done
