I've legit got 0 braincells to cope with this rn
Been doing school shit for like 5 hours already
prisma wave
i think i've got it
jovial warren
@topaz bay hey you can't call me weird anymore because I started writing in Kotlin now lol
jovial warren
no idea what the fuck I was on about before but Kotlin >>>>>>>>>>>>>>> Java any day
hot hull
nah KM
onyx loom
🙂
onyx loom
kotlin good @hot hull
topaz bay
@jovial warren I dont know who you are
onyx loom
@hot hull did u know kotlin good
topaz bay
But good job
hot hull
It's simple, just didn't click in my head at first
topaz bay
Very proud of you
jovial warren
@topaz bay you can't remember the guy who said Java + Lombok is better than Kotlin? lol
topaz bay
Absolutely not.
jovial warren
fair enough xD
jovial warren
well once I found out that Kotlin compiles in to JS as well that definitely steered me toward it
prisma wave
how come lol
jovial warren
because I want to write a plugin with a built-in web interface
and knowing I don't even have to touch JS lol
you know how litebans has the php bans page?
jovial warren
my friend told me I could put is it ktor? embedded in to the plugin
so you don't even need to install a web server with php
prisma wave
yeah Ktor is pretty nice
jovial warren
I'm not sure yet though if I should also provide some sort of php-based web interface as well
or I should just add the stylesheet as an optional dependency in like the plugin's data folder or something
heady birch
spring
jovial warren
spring?
obtuse gale
big rip, my next year course at school focusses on php
jovial warren
heard of it before, got no idea what it is or how it works
yeah php is a weird language
I don't really think JS is that much better though
as a language
js is probably a better option than php though, since it's more responsive
prisma wave
@lunar cypress i just realised after I submitted that I could've removed all my imports 😭
prisma wave
possibly
my actual functionality is 2 lines
val N = readLine()?.toIntOrNull() ?: return
for(i in 1..N step 2) println(i)```
remote goblet
skript always wins
jovial warren
I don't know whether I could agree with that @lunar cypress
Kotlin wins since it compiles to Java and JS
lunar cypress
..what?
prisma wave
oh yeah python still wins
jovial warren
so you only need one codebase
prisma wave
@jovial warren we are talking about something else lol
prisma wave
trying to get the smallest code possible to print odd numbers
prisma wave
yeah lol
jovial warren
yeah python usually wins things like that
prisma wave
poor guy using Java
lunar cypress
This is my code ```clj
(run! println (filter odd? (range (inc (read)))))
But I need to specify an entry point and a namespace unfortunately
jovial warren
Java usually comes last in tests like that
prisma wave
😭
jovial warren
Kotlin comes somewhere in the middle I think
lunar cypress
that is correct
jovial warren
it's usually the language with the most boilerplate comes last and the language with the least boilerplate comes first
jovial warren
nice
prisma wave
rip
jovial warren
thing is though Java wasn't built for compactness, it was built on it's WORA policy
probably why it's got so much boilerplate
topaz bay
that.... isnt true
jovial warren
but Java was heavily built around that policy
jovial warren
yeah not an excuse for so much verbosity
rotund egret
Probaby has more to do so with that Java is built for readability
jovial warren
sounds about right
prisma wave
possibly
onyx loom
hey guys
prisma wave
yo
onyx loom
who wants to do a code review
prisma wave

jovial warren
go on then
heady birch
}
catch (e: KotlinNullPointerException) {
Don't catch NullPointerException
heady birch
😠
prisma wave
don't catch any RuntimeExceptions
onyx loom
aw
prisma wave
most of the time using !! is a bad idea
jovial warren
yeah don't catch null pointers
heady birch
You need to add a lie checker
onyx loom
it was recommended by IJ
prisma wave
IJ is dumb
unless you have VERY good reason you should never use !!
it doesn't solve any problems, it just defers them
jovial warren
IntelliJ sometimes tells you to do smart things and sometimes tells you to do stupid things
prisma wave
I would null check number, if it's null, send a message and return
lunar cypress
clash of code don't kick me challenge 2020
prisma wave
lol
ocean quartz
Just do return null!! easy
prisma wave
@onyx loom you could also do something like kotlin var number = calc() while(number == null) { println("Invalid Input") number = calc() }
ew
jovial warren
what does !! do again? sorry I'm still kinda new to Kotlin lol
ocean quartz
Asserts not null
jovial warren
ah okay
onyx loom
hmm i was thinking of looping it at first
prisma wave
basically throws an NPE if it's null
ocean quartz
We should call it the Java operator
prisma wave
They're unavoidable
jovial warren
ever since I started using Kotlin though I haven't seen a NPE in ages
lunar cypress
share code @prisma wave
prisma wave
You can't null check everything
rotund egret
Certainly you could
jovial warren
Java is very discrete with NPE's sometimes though
I remember the days of sitting there on debug mode just looking for them
brave minnow
is there a way to save a default folder (stored in the plugin) ?
topaz bay
cant relate
jovial warren
yeah when your command just runs but doesn't do anything
then you gotta run it in debug mode to find out it's a NPE
happened to me all the time
is there a way to save a default folder (stored in the plugin) ?
saveDefaultConfig()?
you can't save folders from what I remember
you can only save files
brave minnow
then other than saveDefaultConfig() ?
topaz bay
You can save folders, but not through the spigot api
jovial warren
and for things other than the config use saveResource()
brave minnow
thx 😄
topaz bay
I did it in voteparty
prisma wave
these are pretty fun @lunar cypress
lunar cypress
yeah they are
topaz bay
brave minnow
if I can't do a full folder it's not a problem it's like a config file and a custom file
jovial warren
is it glaze? something like that, his one is premium
and it doesn't have any DB support
topaz bay
It will
jovial warren
they working on it?
topaz bay
they?
brave minnow
can I use saveRessource() in an expansion ?
lunar cypress
this one was a joke @prisma wave
prisma wave
it was really easy
topaz bay
jovial warren
@topaz bay is that vote party plugin you sent a link to gonna have database support?
ah okay
so it's yours and darbyjack's
jovial warren
wait that's open-source?
hot hull
All of Glare's plugins are
jovial warren
they're premium and open-source?
hot hull
Freemium yes
prisma wave
yes
ocean quartz
Yeah
hot hull
You're paying for support
jovial warren
ah okay
prisma wave
which is very good imo
ocean quartz
Agree
hot hull
Everyone should do that
prisma wave
^
brave minnow
hulp me pls :c
jovial warren
does he have his own spigot page?
brave minnow
@hot hull 👍 
jovial warren
because clip's page for it doesn't mention anything about source code
topaz bay
jovial warren
that's the one I'm on
actually yeah it's not on clip's page
sorry the art being the same confused me
jovial warren
same guy who makes clip's art
topaz bay
jovial warren
no mention of source code on that page though
brave minnow
is there a way to use saveRessource() in an expansion as long as it's not extended from JavaPlugin ? :c
jovial warren
you can't use saveResource() outside of JavaPlugin or an extension of it
you'd have to use a built-in method
prisma wave
Files.copy
jovial warren
actually you could either have the main as a singleton or pass an instance of the main to the subclass using the constructor
ocean quartz
It'd save in the extension's plugin's folder if you did it with it's instance
brave minnow
can you show me an example pls ? I don't really understand ^^'
prisma wave
@lunar cypress anymore?
lunar cypress
yeah, our mate is still lost lmfao
prisma wave
oh yeah lmao
poor guy
@brave minnow you'll probably need to read from ClassLoader#getResource and copy to your file. Have a look how saveResource does it
i am pretty sure there's a method somewhere in Files for this
ocean quartz
It gets resource as inputstream i think
jovial warren
@topaz bay why are some parts of VoteParty still in Java?
even though most of it's in Kotlin
lunar cypress
we ended his suffering
ocean quartz
Imma join that on my phone
jovial warren
also for DB support I'd recommend just removing raw text file support completely and setting h2 as the default flat file driver, then maybe for people with the old versions you could have it migrate to h2 on startup if the old raw text file still exists or something @topaz bay
ocean quartz
Then take like 30 minutes to type it xD
brave minnow
isn't getRessource good for it ?
prisma wave
getResource won't work in an extension misunderstood, use getResourceAsStream
WHAT
HOW
prisma wave
i was pretty proud of my 1 line factorial function
lunar cypress
by 2 seconds lol
jovial warren
how do I ask glare?
topaz bay
?
jovial warren
what's his username?
topaz bay
hes literally in this server?
prisma wave
using java is just shooting yourself in the foot here lol
lunar cypress
what was your solution bm?
prisma wave
yeah pretty much lol
jovial warren
@topaz bay couldn't recognise his username lol
onyx loom
wat
jovial warren
he's got dm's from server members turned off, don't really blame him to be fair lol
ocean quartz
The waffle king
jovial warren
yep
I mean I could always fork the plugin, make my changes, then submit a merge request
probably best to talk to him about my proposed changes though
@frail glade I heard you were planning on adding database support for VoteParty, thought I'd propose a plan. I think you should just use relational databases and scrap raw text files completely, preferably using H2 as the default driver, then possibly adding in a migration system for the old raw text file system to H2, since there isn't really a reason to support raw text files once you support H2 anyway.
jovial warren
lol
onyx loom
how do i fix this 🙃
jovial warren
needed a notnull int and got a nullable int
onyx loom
hmm k
onyx loom
https://paste.helpch.at/urajiqusek.cs i took ur advice with the code review but idk if im doing it right haha
im in the dark here so ignore me
jovial warren
number is of type Int
it's inferred
toIntOrNull() returns a nullable integer, or Int?
onyx loom
when u said number = calc(), it was throwing a different error, so i put it to number = 0
jovial warren
try val number: Int? = 0
that will tell kotlin explicitly that you want a nullable integer
also I'd suggest just parsing number as a parameter to calc()
jovial warren
either that or change it to var
onyx loom
then it can be ig
prisma wave
Realistically number shouldn't be a global variable
prisma wave
1 method should parse the user input and return it, another method should check the input
onyx loom
ill get there eventually haha
prisma wave
eg kotlin fun main() { val age = readIntFromInput() validateAge(age) } something like that
jovial warren
also, repeated code
just put the println("You are $number years old.") outside of the if statement
frail glade
I probabaly won't add database anytime soon. It's not a priority.@jovial warren
hot hull
Glare should probably answer the guy in #general-plugins if you haven't already
onyx loom
thats how i had it at first, idk why i repeated it actually
jovial warren
@frail glade alright, I could just fork it and implement it myself then submit a merge request I guess
frail glade
If you want to
prisma wave
you've got a bit of spaghetti logic going on here @onyx loom . you go from main() to calc() and then back to main() over and over. You should have 1 function that loops until they put in a valid int, and then return that int
frail glade
I don't plan to rid flatifle support tho
jovial warren
H2 is flatfile
frail glade
Idc, I like json
jovial warren
alright
frail glade
You're welcome to offer a MySQL implmentation.
prisma wave
this is why OSS good
jovial warren
OSS?
frail glade
Ikr. I can go back to bed now.
prisma wave
https://img.bristermitten.me/14.07.18-2020.png @lunar cypress 😳
jovial warren
get that out of here right now
hot hull
What the fuck lmao
onyx loom
ye i will do that when i get parameter passing, but for now spaghetti good.
@prisma wave ^
prisma wave
spaghetti bad
onyx loom
😄
prisma wave
😦
prisma wave
strange
brave minnow
@prisma wave what should be the input stream to get the file in the plugin ?
prisma wave
ClassLoader#getResourceAsStream
brave minnow
kay :p
prisma wave
or just Class#getResourceAsStream
so eg getClass().getResourceAsStream("config.yml")
that one might not work tho
brave minnow
why ? 🤔
prisma wave
because papi & spigot both do some weird classloader stuff that can cause problems
Class#getResourceAsStream has never worked in my experience but you can try
@lunar cypress any more?
lunar cypress
missed the last one, currently waiting
lunar cypress
ok, most of the others left
so that's it for now
if enough people from this server participate, we can also do that some time
heady birch

prisma wave
What does it say is wrong?
Although that might be for the kotlin DSL, try this https://github.com/JetBrains/Exposed/wiki/LibDocumentation
The groovy syntax is slightly different
lunar cypress
The snippet up there only works with kotlin
With groovy you can't separate artifact, group and version like that
brave minnow
@prisma wave sry a bit late but what should go in copyOption ? ^^'
brave minnow
so null ?
old wyvern
Umm shortness of breath is not a initial symptom of covid right?
brave minnow
Paths.get("plugins/PlaceholderAPI/mli/") how can I make a relative path ?

brave minnow
InputStream config = this.getClass().getClassLoader().getResourceAsStream("Language.yml");is it correct at least ?
@prisma wave help my deadass brain pls '-'
prisma wave
Looks good
brave minnow
why is null then ? :c
prisma wave
That's a good question
The answer might be Papi and spigot being weird
Is the file present in the jar?
hot hull
What is you even trynna do btw
obtuse gale
Is that....
brave minnow
is that ?
brave minnow
yes don't try to understand I also have ij '-'
prisma wave
https://img.bristermitten.me/15.12.31-2020.png that's a nice cry for help
brave minnow
yes it is x)
obtuse gale
white theme as well tho
brave minnow
I got in on every load lol
prisma wave
@brave minnow 2 things:
make sure the file is inside the jar
try Class#getResourceAsStream
if both of those fail then you might need to try something cleverer
brave minnow
I like the pain
onyx loom
i love pain too
prisma wave
don't we all
onyx loom
reeeeeeeeee
prisma wave
is the file in the exported jar?
brave minnow
yus
@prisma wave is it possible to grab from jar file with those ? ```private FileConfiguration customConfig = null;
private File customConfigFile = null;
Not really, you need to get the file from inside the jar somehow. does getClass().getResourceAsStream work?
prisma wave
wdym?
jovial warren
it is possible to get files from those configurations
as long as you initialise them
I think File has a load() method
prisma wave
FileConfiguration does, the difficulty is getting a File
jovial warren
this is why you're supposed to load configurations using the main class
since that one has the data folder
getDataFolder() in Java
prisma wave
this isn't a plugin
jovial warren
what is it?
prisma wave
an expansion i believe
jovial warren
an expansion of a plugin?
prisma wave
for papi
jovial warren
ah okay
the only time you make PAPI expansions though is with a plugin
unless you're trying to make an expansion to bridge PAPI and another plugin that doesn't use PAPI
which seems like a bad idea
prisma wave
you can have standalone papi expansions
jovial warren
purpose.exe not found
brave minnow
yep but I would say generate the file and the config from api methods
jovial warren
what are you actually trying to make?
brave minnow
the expansion or the file ?
jovial warren
the whole project
brave minnow
translatable placeholders
jovial warren
placeholders that can be translated in to other languages?
brave minnow
yes
jovial warren
what files are you trying to write? locale files?
brave minnow
yes
brave minnow
yes
brave minnow
yep but can't put one in the java archive and extract it :/
jovial warren
you using maven?
brave minnow
nope
jovial warren
gradle?
brave minnow
neither
jovial warren
any form of build automation tool?
brave minnow
nah
jovial warren
if you're using build path that's the first thing I would change
but that's not important
for the moment
brave minnow
why ? 🤔
jovial warren
makes dependency management like a million times easier
brave minnow
I guess ^^
prisma wave
easier, platform agnostic, more extendable, handles things like shading, etc
jovial warren
^^^^
prisma wave
but I think the problem is that papi's (and spigot)'s loading of classes suck
jovial warren
I would've thought PAPI's API would have some way to get the data folder
jovial warren
ah okay
so there's not a problem saving the file to the right place or what?
or is it just not bundling properly
brave minnow
there's a problem to grab the file not save it
prisma wave
https://github.com/PlaceholderAPI/PlaceholderAPI/blob/82fa8d7393442e18619b9c99192bf6f030be2874/src/main/java/me/clip/placeholderapi/util/FileUtil.java#L79 possibly because of this
brave minnow
file in jar jar in papi folder
jovial warren
yeah that's definitely questionable @prisma wave
prisma wave
i tried to make a kotlin script expansion for papi
the amount of class not found errors I experienced was horrific
jovial warren
making an efficient, user-friendly, working, actually looks like programmer gives a shit about end user API is harder than you think
although when the entirety of your project is an API you'd expect it to be written well
jovial warren
also why is it loading classes?
prisma wave
For the expansion to run
prisma wave
to load the classes from the jar?
but loading all the .class files is a questionable decision when URLClassLoader can load full jars in 1 line
jovial warren
sorry I don't know much about loading classes
jovial warren
I've never ever had to load classes
prisma wave
I had to make a module system a few years ago so I picked up a lot then
jovial warren
so that should be used to just load entire JAR files rather than separate classes?
prisma wave
indeed
there's no reason to iterate over the JarEntries when URLClassLoader can just load the entire jar
jovial warren
also yeah I've never made an API before so probably why I haven't ran in to things like this
prisma wave
which will include resources as well
jovial warren
if I want to optionally hook in to PAPI though I'll need to use this API won't I
though that method won't apply for me since I'll <scope>provided</scope> the PAPI API maven module
prisma wave
yeah PAPI won't need to load any classes in that case
the classloading is done for standalone expansions that aren't plugins
jovial warren
if you're wondering what I'm working on it's a free and open-source punishments plugin with built-in web server, bukkit and bungee support, possibly placeholder support, and as if not more customisable than paid alternatives such as LiteBans
also with a better API than LiteBans
currently a WIP
but anyway
brave minnow
is there a way to grab all file name in a dir ?
prisma wave
File#listFiles
yeah i remember you mentioning the Litebans rewrite a while back
sounds nice
jovial warren
it's written from scratch in Kotlin
the bukkit and bungee plugins will be separate JARs, unlike pretty much every other punishments plugin I seem to be able to find, mainly because I personally think having separate JARs is easier to distinguish between the versions
oh I forgot to mention that it has full database support as well
H2, MySQL, MariaDB, hopefully PostgreSQL, and SQL server I think
can't add MongoDB because it's not relational
anything else you think I should add?
jovial warren
yeah probably
prisma wave
nice
jovial warren
something I can embed in to the plugin
so that it doesn't even depend on an external web server like LiteBans does
not sure how I'm going to make it configurable
prisma wave
I think you should release the webserver as a standalone jar
so people can run it on a vps or something if they want
prisma wave
Kotlin/JS ?
prisma wave
even so
brave minnow
in case I'm making a placeholder expansion stored in papi folder the path to it (from the jar of expansion) will be plugins/placeholderapi/expansions isn't it ?
jovial warren
should it be a JAR if it's got no Java in it though?
brave minnow
well gud 😄
jovial warren
yeah
brave minnow
so File("plugins/placeholderapi/expansions") will show me the dir of it no ? 🤔
jovial warren
I want to make it be able to run standalone though
I mean the plugin
without actually requiring that the web server be added to be able to use it
if you know what I mean
jovial warren
yeah
prisma wave
@brave minnow I don't think so. new File("") will be `plugins/placeholderapi/expansions I believe
jovial warren
I could bundle it in to the JAR and then make it configurable
and yeah should be
also where's the PAPI maven dependency?
please don't tell me it doesn't have one

cheers
found it on the wiki
was just confused because it wasn't on the front page lol
also if I implement it in my plugin you don't need to make an expansion for it right?
hot hull
Nope
jovial warren
these expansions are just for the plugins that don't have it implemented in them right?
jovial warren
that answer is memory
I mean where are you storing it as in: if the server goes down, what happens?
hot hull
End goal for warp storage is gonna be mysql/flatfile
somber tulip
Is that per player warps too frosty? c:
jovial warren
if you want DB support I'd suggest just scrapping raw text file support
somber tulip
Good man
jovial warren
what I mean by that is just use H2 or SQLITE as the default driver
and scrap things like JSON, YAML or Plain Text
hot hull
We'll see what's easiest to use I guess
jovial warren
just, I wouldn't implement MongoDB support
since MongoDB isn't a relational database
also I'd suggest using some sort of object-relational mapping software
for Java I recommend ORMLite and for Kotlin I recommend Exposed
if you don't know what ORM is basically it just takes executing raw queries out of your hand by using objects that represent columns in a database

What's the cleanest way of validating that an input string exists as an enum?
heady birch
Spring
prisma wave
spring
hot hull
Cause valueOf throws ew errors if it doesn't
prisma wave
Enums.getIfPresent or something iirc
heady birch
A DTO
prisma wave
Enums.valueOf maybe
heady birch
Then @Valid annotations
hot hull
Km boi
heady birch
Build a validation
prisma wave
yes
ocean quartz
Enum's value of throwing error is so annoying, just return null
heady birch
final class final MyStringInput {
final @NotNull
final @MyEnumExists
final private final String final input;
final public final void final setInput(final String final input) {
final this.final input = final input;
}
final public final String final getInput() {
final return finalinput;
}
}```class MyStringInput {
private val input: String;
}
isn't that literally enough for Kotlin or is it just me lol

nvm that won't work
heady birch
Not enough OO
prisma wave
this needs improvement
heady birch
Not enough boiler plate
jovial warren
lol
heady birch
Not enough enterprise
jovial warren
I hope you're not actually being serious @heady birch xD
hot hull
public static boolean isValid(final Warp.Category inputEnum, final String input) {
Warp.Category being any enum I desire
heady birch
I think I misunderstood what he wanted anyway
hot hull
You get what I mean now?
prisma wave
not enough boilerplate you say?
heady birch
Why do this
prisma wave
bear with
hot hull
Because that's not the only enum I'm gonna be using it for
heady birch
Well then it wont work
jovial warren
also @hot hull you should learn Kotlin
hot hull
Bardy, be gone.
heady birch
use type
hot hull
type?
heady birch
public <T extends Enum<T>> boolean isValid(Enum<T> theEnum, String theEnumValue) {
for (T val : theEnum.values()) {
if (val.name().equalsIgnoreCase(theEnumValue)) {
return true;
}
}
return false;
}
Frosty is a hater 😢
jovial warren
someone should change this to say Java and Kotlin instead of Eclipse and IntelliJ lol
hot hull
why is that a void and a boolean Niall :p
prisma wave
smh
heady birch
Lol lmao
public <T extends Enum<T>> boolean isValid(Enum<T> theEnum, String theEnumValue) {
for (T val : theEnum.values()) {
if (val.name().equalsIgnoreCase(theEnumValue)) {
return true;
}
}
return false;
}
Havnt tested it should work
I cant even remember where the T definition goes
Do you like my apihttps://github.com/Niall7459/KiteBoard-Documentation/wiki/Developer-API
jovial warren
you want me to pick it apart?
heady birch
Criteria.Factory<MyCriteria> factory = MyCriteria::new;```Uses nice genreics
pick it apart?
if you mean criticize yes
would like to know how/if it can be improved
jovial warren
by pick it apart I basically mean go through it and find pretty much every fault there is lol
jovial warren
also if it's an API it always be improved
heady birch
Oh I like that
prisma wave
I made it as slow as possible
jovial warren
lol
prisma wave
Including useless concat() and toLowerCase() calls
heady birch
Oof
jovial warren
oh and it's written like that
prisma wave
Should probably add some Thread.sleep calls so we can make a nice progress bar
heady birch
Yes!
jovial warren
yeah
hot hull
I'm lost Niall
heady birch
BM do you like my api
prisma wave
I've not seen it much
jovial warren
what's it an API for @heady birch ?
heady birch
Kiteboard
hot hull
=pl kiteboard
compact perchBOT
hot hull
This bad boi
prisma wave
"enterprise" 👀
heady birch
Also I documented one part wrong
prisma wave
Does that mean what I hope it does
heady birch
Do what
jovial warren
RegisteredServiceProvider<KiteBoard>serviceProvider = getServer().getServicesManager().getRegistration(KiteBoard.class);
not sure about that one
hot hull
I've legit no clue what I'm doing at this point
heady birch
Over .load(
jovial warren
I'd suggest just having some sort of API singleton main class and then just getting the instance
heady birch
😕
jovial warren
pretty sure LuckPerms does it the way I'm thinking of hold on
heady birch
@hot hull I will try in ide
jovial warren
https://github.com/lucko/LuckPerms/blob/master/api/src/main/java/net/luckperms/api/LuckPerms.java there it is
https://github.com/lucko/LuckPerms/blob/master/api/src/main/java/net/luckperms/api/LuckPermsProvider.java and it's used from here
then lucko registers the API in the plugin I think
might be wrong there
yeah common depends on the API
prisma wave
prisma wave
wait that's wrong
hot hull
That's hella quick KM
heady birch
@hot hull
public <T extends Enum<T>> boolean isValid(Class<T> theEnum, String enumName) {
for (T val : theEnum.getEnumConstants()) {
if (val.name().equalsIgnoreCase(enumName)) {
return true;
}
}
return false;
}
Reflection to get the constants
jovial warren
you've passed that a Class object though
I wouldn't've thought that object would have the getEnumConstants() method
or am I just talking out of my arse
heady birch
Warps.Category.class
jovial warren
ah okay
never had to do what he's doing before
also someone put that in to kotlin
I'm just curious what it'd look like
fun <T : Enum<T>?> isValid(theEnum: Class<T>, enumName: String?): Boolean {
for (value in theEnum.enumConstants) {
if (value!!.name.equals(enumName, ignoreCase = true)) {
return true
}
}
return false
}
ayy, works
jovial warren
that's what I got from IntelliJ
jovial warren
probably
prisma wave
inline fun <reified T : Enum<T>> isValid(name: String) : Boolean {
return enumConstantsOf(T::class.java).any {
it.name.equals(name, true)
}
}```I believe it would be that
but I typed it on mobile so
Then you could do like isValid<Material>("stone_bricks")
jovial warren
fun <T: Enum<T>?> isValid(theEnum: Class<T>, enumName: String?): Boolean = theEnum.enumConstants.forEach { it?.name == enumName } @prisma wave ?
prisma wave
You can access the class of a type parameter
jovial warren
actually no that returns Unit
prisma wave
reified means you can do T::class

@jovial warren enumConstantsOf is a thing that does the reflection for you, and I would avoid the nullability, and use any instead of forEach
hot hull
Happened two times within 2 days already, anyone got any idea why?

fun <T: Enum<T>?> isValid(theEnum: Class<T>, enumName: String?): Boolean = theEnum.enumConstants.any { it?.name == enumName } so this @prisma wave ?
prisma wave
I've noticed it seems to happen a lot on win 7
heady birch
Whats your fav template engine for spring BM?
hot hull
It hasn't happened in the last 6 months i've been using IJ, and now it started, sus af
prisma wave
@jovial warren that would work but for QoL I would not allow nullable things
I've only ever used thymeleaf
jovial warren
that return type can also be inferred
heady birch
freemarker and mustache, never used them though
jovial warren
I think the rule with inferences is if it's nullable it must be defined explicitly, otherwise it can usually be inferred
prisma wave
But you should be careful with inferred return types, unless the body is clear then it can be somewhat difficult to read
Nullable types can be inferred too
jovial warren
lemme correct that
heady birch
And goovy templates
prisma wave
Which can actually work against you
heady birch
yieldUnescaped '<!DOCTYPE html>'
html {
head {
title('Spring Boot - Groovy templates example')
link(rel: 'stylesheet', href: '/css/bootstrap.min.css')
}
body {
div(class: 'container') {
div(class: 'navbar') {
div(class: 'navbar-inner') {
a(class: 'brand',

}
}
}
div("This is an application using Boot $bootVersion and Groovy templates $groovyVersion")
}
}
}
That's intersting
prisma wave
yikes
jovial warren
the rule with inferences is: if the type you want to return is being returned by the method you're using, it can be inferred
ocean quartz
I really love Kotlin
hot hull
Also KM, I wouldn't be surprised if it's IJ since I'm using version 2018.3 :kek:

@jovial warren this shows when inference can be a bad idea sometimes https://twitter.com/kotlin/status/1255882186559029248?s=19
jovial warren
that must've bugged you every time you opened it up that it needs an update
hot hull

@ocean quartz destructuring is hands down of Kotlin's best features
prisma wave
some things can be destructured if they override the component operators
jovial warren
one of my favourite features is the ability to add methods to existing classes
prisma wave
So for example ```kotlin
playerXP.entries.forEach { (player, xp) ->
}
ah okay
prisma wave
Which is a lot more useful than it sounds
You can destructure lists like in Matt's example
jovial warren
yeah right now I'm like "usage.exe not found"
prisma wave
val (first, second, third) = listOf(1, 2, 3)
It's mostly for QoL
Makes working with regexes a lot nicer for example
ocean quartz
Basically any data class can be destructured into their independent variables
jovial warren
what are your thoughts on being able to add methods to existing classes though?
sounds useful
jovial warren
fun LocalDateTime.add(duration: String): LocalDateTime? {
if (!duration.matches("((\\d+)\\w*)+".toRegex())) return null
val matcher = "(\\d+)([a-z]*)".toPattern(Pattern.CASE_INSENSITIVE).matcher(duration)
var result = this
while (matcher.find()) {
val amount = matcher.group(1).toLong()
val unit = when {
matcher.group(2).matches("s(ec(onds?)?)?".toRegex()) -> SECONDS
matcher.group(2).matches("m(in(utes?)?)?".toRegex()) -> MINUTES
matcher.group(2).matches("h(ours?)?".toRegex()) -> HOURS
matcher.group(2).matches("d(ays?)?".toRegex()) -> DAYS
matcher.group(2).matches("w(eeks?)?".toRegex()) -> WEEKS
matcher.group(2).matches("mo(nths?)?".toRegex()) -> MONTHS
matcher.group(2).matches("y(ears?)?".toRegex()) -> YEARS
else -> SECONDS
}
result += Duration.of(amount, unit)
}
return result
}
that is so useful to have
prisma wave
Pretty much the first thing I write in any project is String.color to process color codes
jovial warren
you wanna know what that was in Java?
prisma wave
Some hideous helper method probably
jovial warren
public static long convertDuration(final String duration) {
Matcher regex = Pattern.compile("(\\d+)([a-z]*)").matcher(duration);
long milliseconds = 0L;
while (regex.find()) {
int amount = Integer.parseInt(regex.group(1));
switch (regex.group(2)) {
case "s": case "sec": case "second": case "seconds":
milliseconds += amount * 1000L;
continue;
case "m": case "min": case "minutes":
milliseconds += (amount * 1000L) * 60L;
continue;
case "h": case "hour": case "hours":
milliseconds += ((amount * 1000L) * 60L) * 60L;
continue;
case "d": case "day": case "days":
milliseconds += (((amount * 1000L) * 60L) * 60L) * 24L;
continue;
case "w": case "week": case "weeks":
milliseconds += ((((amount * 1000L) * 60L) * 60L) * 24L) * 7L;
continue;
case "M": case "mo": case "month": case "months":
milliseconds += ((((amount * 1000L) * 60L) * 60L) * 24L) * 30L;
continue;
case "y": case "year": case "years":
milliseconds += ((((amount * 1000L) * 60L) * 60L) * 24L) * 365L;
}
}
return milliseconds;
}
that mess
prisma wave
Oh dear god
onyx loom
YUCK
jovial warren
yep
prisma wave
I'm pretty sure there are ways to clean that up even more
Iirc you can destructure a Matcher for example
But you should definitely be caching those regexes
toRegex() is the same as Pattern.compile so it should be cached
jovial warren
the left one was stolen straight out of MaxBans lol
Kotlin really clears up your code a lot though
prisma wave
it really does

ngl, the second one is spicy af
jovial warren
https://github.com/Prevarinite/Punishments/blob/master/src/main/java/com/prevarinite/punishments/commands/BanCommand.java that's my old ban command lol
