jovial warren
to acknowledge player digging
but it's 1.15+ (from what I've read), meaning it didn't always exist
@ocean quartz I don't think there's a way to step back since it's pretty much impossible, as when you advance, you're advancing the program's execution, and you can't just turn back the clock like that
jovial warren

I will try to explaim here

So, I found dependencies that in <dependency> the Scope is not provided
by that pom
jovial warren
I swear PDM doesn't even support Shitven lol
astral quiver
instead, looks like it is provided by the parent pom
I will send a sample for you folks
astral quiver
But, the way that PDM does is looking into the <dependency>
jovial warren
since when did PDM support Maven
prisma wave
it supports maven repositories
since that's the standard
it doesn't have a maven plugin

it's ?
jovial warren
nah don't bother making a Maven plugin, fuck Maven users xD

distant sun
should i replace filter {}?
you said smth about not creating new collections
I guess sometimes that cant be avoided?
prisma wave
Oh
nah I think in this case trying to do it all in 1 line would hinder readability
however
if you're dealing with a lot of data, or a lot of operations it can be useful to use sequences instead of collections sometimes
since it's faster + less memory intensive
distant sun
there can be max 36 items on that inventory and items usually have 3 - 10 enchantments, may 15
prisma wave
yeah probably fine
distant sun
that are sequences though
prisma wave
?
distant sun
what*
prisma wave
ah
like java streams
but faster
I wrote a blog post about it but looks like it's been yeeted ๐
but basically, they process each element individually rather than making intermediate collections
like an iterator + loop
distant sun
uh
sequence<MutableMap.MutableEntry<CEHandler, Int>> { api.getEnchantments(item).entries }
.filter { it.key.isRefundable }
.sumByDouble { 2.0 }```
so like this?Maybe you could use Maven Aether just in the gradle plugin to do a better dependency resolution @prisma wave
Kotlin Sequence is really awesome
distant sun
is a map

oh, storry, this is a article sample

astral quiver
in this sequence, this is really more efficient @prisma wave ?
astral quiver
A good example would be like: first { it.age > 35 }
this could be a really good example
prisma wave
yeah I was trying to think of practical examples I guess
astral quiver
but, I guess, this is still more efficient then doing collections operations
prisma wave
indeed
astral quiver
Just want to think about it one sec
The problem is that Kotlin creates new collections everytime if I recall
prisma wave
correct
astral quiver
that could be needed in case like a linkedlist mutable implementation
because this operations use inline function
that I think is not the case for the Sequence
jovial warren
what are peoples' obsessions with doing thingys like this in Kotlin: kotlin fun myFunction(): Int { return 1 } instead of just ```kotlin
fun myFunction() = 1
expression functions = good
also challenge for you lot: try writing a program that prints the factorial of a given number n without running in to an integer overflow
prisma wave
expression functions = good
@jovial warren only in situations where readability isn't hindered. In that example a property without a backing field is probably better
jovial warren
yeah ik that's better in that case, but I was saying in general, people use single return thingys rather than expression functions
prisma wave
eh
I think situations where using an expression function would be better are quite limited
jovial warren
wat
prisma wave
I've seen very few situations where I've thought "you should use an expression function here"
they're very niche
possibly even a gimmick
but then again elara has them too, so can't be a hypocrite
jovial warren
also challenge for you lot: try writing a program that prints the factorial of a given number
nwithout running in to an integer overflow
also do this
prisma wave
on it rn
jovial warren
what you using?
jovial warren
because I wanna find a tool I can use to just throw a program together
prisma wave
overflow is gonna be caused by the data type you're using
BigInteger effectively makes overflow impossible
jovial warren
yeah I figured that one out after I'd wrote my initial program
what tool you using? just regular IJ?

how is recursion faster than tail recursion?
prisma wave
ยฏ_(ใ)_/ยฏ
jovial warren
show me
jovial warren
because mine looks like this: ```kotlin
tailrec fun factorial(number: BigInteger, accumulator: BigInteger = BigInteger.ONE): BigInteger = when (number <= BigInteger.ONE) {
true -> number * accumulator
else -> factorial(number - BigInteger.ONE, number * accumulator)
}
also don't even ask

mine is testing 1000 times and taking the average
although the compiler might have optimised some of the calls out
since i'm not using jmh or anything
Go would never have this problem
every operation = 0.005ms
i just realised
a factorial function is O(n) not O(n!)
huh
jovial warren
tailrec fun BigInteger.factorial(accumulator: BigInteger = BigInteger.ONE): BigInteger = when (this <= BigInteger.ONE) {
true -> this * accumulator
else -> (this - BigInteger.ONE).factorial(this * accumulator)
}
```this is better xDno it's not
jovial warren
yes it is
it's an extension function
I don't mean better in performance, I mean better than my last one
prisma wave
using when in place of a single if/else is gross
https://img.bristermitten.me/idea64_WQYm1dnSMQ.png
when getting 5000! fold seems to be fastest
jovial warren
what are you on btw
prisma wave
?
jovial warren
using when in place of a single if/else is gross
jovial warren
if (thingy) {
} else {
}
```looks worse than ```kotlin
when (thingy) {
true ->
else ->
}
you wouldn't do ```java
switch (condition)
case true: break
case false: break
}
at least have true and false instead of true/else
jovial warren
no because switch is weird and overly verbose, when is nice and clean
prisma wave
how is it weird
jovial warren
how is it not
prisma wave
because it isn't?
jovial warren
it only works on constants and primitives
prisma wave
yes
because unlike when it doesn't compile to if else
it's a standard switch case implementation
anyway
when should only be used for 3 or more branches
empty flint
if (thingy) {
} else {
}
```looks worse than ```kotlin
when (thingy) {
true ->
else ->
}
@jovial warren
if (thingy)
{
}
else
{
}
jovial warren
I mean, kotlin if (thingys) doThingys() else doOtherThingys() >```kotlin
when (thingys) {
true -> doThingys()
else -> doOtherThingys()
}
but single-line braced if-else statements look disgusting
prisma wave
if expressions should always have braces
jovial warren
again, another opinion that you're stating as fact
well I mean, you do use allman so that just explains it all I guess
jovial warren
find it in the specification and I'll accept it as fact
also if it wasn't an opinion, single-line non-braced if statements wouldn't be a thing
prisma wave
bruh
specification doesn't define everything
find "arrow code bad" in the specification
jovial warren
also if it wasn't an opinion, single-line non-braced if statements wouldn't be a thing
prisma wave
you realise that mistakes can be made in language design
jovial warren
yeah, but Java did it before Kotlin, and Kotlin decided to keep it in
prisma wave
I highly doubt they would've deliberately added it had Java not had it
jovial warren
why wouldn't they've
prisma wave
because it's commonly regarded as a bad idea to use it
jovial warren
without single-liners, val x = if (condition) y else z wouldn't be a thing
which is basically Kotlin's answer to ternary operators
distant sun
ternary operators look better ๐คท

this is one of the things that turns me off of functional programming
heady birch
If you can write assembly you can write pure binary
prisma wave
Map, filter, etc are all elements of functional programming
jovial warren
I don't mean first class functions are bad, I mean declaring variables and functions the same is bad
prisma wave
but why?
distant sun
Cuz it is.
jovial warren
because it gets confusing
prisma wave
If they're both identifiers + values, why should they be declared differently?
jovial warren
because it makes your code more readable
prisma wave
does it though?
jovial warren
because you should be able to easily distinguish between a variable and a function
prisma wave
First class functions
this is one of the things that turns me off of functional programming
@jovial warren
I don't mean first class functions are bad
@jovial warren
Also make your mind up lol
you can easily distinguish
By looking at the value
jovial warren
First class functions
@jovial warren
@jovial warren
Also make your mind up lol
I did make up my mind
I literally said that I meant by that original message that I meant first-class functions aren't bad, but your implementation of them is
prisma wave
What elara does is entirely possible in kotlin
val printHello = {
println("Hello")
}```having separate syntax for function declaration implies that they're separate things, even though they're not
jovial warren
that's an SAM-converted anonymous function, not a function declaration
jovial warren
also that code is not something that anyone does in Kotlin because you just don't do that
prisma wave
Why not?
heady birch
Ruby on rails vs spring
jovial warren
because it's bad
jovial warren
Ruby on rails vs spring
Spring better because it supports Kotlin
@prisma wave just look at that original thingy you sent
why isn't that bad
that's what I wanna know
heady birch
Kotlin + spring = ๐
jovial warren
@heady birch what the damn hell you been smoking this morning
prisma wave
Because it treats functions identically to any other values, and therefore makes passing functions around much more concise
heady birch
I have yet to experience its power
jovial warren
do you use Kotlin or not yet?
prisma wave
You could do ```
service.execute(printHello)
Instead of ```
service.execute(this::printHello)
I guess
prisma wave
If we're going to the extremes of not distinguishing between functions and variables, a variable could just be considered a function that returns itself

jovial warren
does abstraction work in Elara?
(I mean methods without implementations, like in interfaces)
prisma wave
interfaces are more of an OOP concept although I am considering adding them
Probably wouldn't be necessary
abstraction isn't a thing
Not needed
Contract based
jovial warren
if you add more OOP principles in to Elara then I might consider using it
jovial warren
does it have all four key principles?
prisma wave
Kind of
jovial warren
those being:
- Inheritance
- Abstraction
- Encapsulation
- Polymorphism
prisma wave
Not in a traditional sense
But they are possible in a way
Although I'd argue those aren't exclusive to OOP
Probably the main OOP "feature" is the concept of a method
jovial warren
without those four key principles, you don't exactly have "all the OOP you need"
prisma wave
they can be replicated but they aren't specifically in the language
It's about as object oriented as Go is
Which is roughly "not entirely but kind of"

Kotlin has both lazy and eager "streams"
If you dont explicitly specify that you want to use the Sequence api, you dont get the same result as using Java streams
As in intermediate collections are made
jovial warren
most of the time, the benefits of sequences aren't all that worth it though
unless you're computing a lot of data, or doing something where performance is a massive deal
prisma wave
Sequences massively reduce the number of operations and memory count when you have a lot of transformations
old wyvern
mhm
jovial warren
yeah exactly what I said, worth it if you've got loads of data to compute or where performance makes a difference
old wyvern
Why did kotlin add the eager implementations? just to make collection transformation easier?
jovial warren
which ones are eager?
old wyvern
Collection#filter ...ect are eager
old wyvern
You need to use Collection#asSequence to begin using the sequence api
jovial warren
isn't the difference that lazy means the data only gets used when it's needed, and eager means it basically uses as much data as it can
prisma wave
For simple stuff there won't be any noticable overhead
old wyvern
yes bard
jovial warren
like I remember quantifiers in Regular Expressions being eager or lazy, eager meaning it takes as many as it can, giving back if it needs, and lazy means it only takes what it needs
prisma wave
Mhm
old wyvern
The Kotlin Sequence/ Java Streams do nothing unless you specify a terminal function
jovial warren
actually it's not eager in my case, it's greedy
(I mean it's referred to as "greedy" rather than "eager", but the same principles apply anyway)
old wyvern
Im pretty sure its reffered to as the "eager" implementation in this case

how do you explain to someone the reason for using stuff like Gradle instead of just importing jars
@remote goblet gradle go brrrrr

@remote goblet yes, maven go brr, gradle go brrrrr

maven go ew gradle go br

@remote goblet fast building, extendable, makes dependency management easier
quiet depot
regarding why to use a build tool, I have a reason on my gradle guide
hot hull
Gradle: Your gun goes pew pew, mine goes brrrrrrrrrrrrrrrrrrrrrrr
prisma wave
Just use a load of terms like "platform agnostic" and "reproducible" to make yourself sound smart

Is there a way to force a subclass to implement either one method or another, but not both?
hot hull
Any reason why you want it to be forced?
quiet depot
Is there a way to force a subclass to implement either one method or another, but not both?
no
prisma wave
messy
quiet depot
use interfaces
prisma wave
Incredibly messy
hot hull
Just have both as default and use the one you want, ez claps
empty flint
idk how to do this actually other than having two different abstract classes
so here's the thing
prisma wave
I swear all of your questions are "how do I do this impossible hacky thing"
empty flint
I swear all of your questions are "how do I do this impossible hacky thing"
@prisma wave Yeah cuz I don't have to ask about the easy stuff ๐
It's survivor bias
Anyhow
old wyvern
Whats the point of having then implement either A or B?
empty flint
here's what I need to do and idk how to do it cleanly
prisma wave
Interface segregation principle
empty flint
there's this api with two methods. One takes a functional interface (Foo) -> Int
and one takes a functional interface (Foo) -> Unit
and I want my classes to implement either one but not both
and depending on which one is used, that method gets called
hot hull
Just have two methods, both be default and just call both?
And then you just implement either or in your class
empty flint
Yeah that's what I did but it feels messy
quiet depot
it is messy
use a mixin-esque pattern with two interfaces
thatโll yield the cleanest result imo
hot hull
What's that Piggy?
quiet depot
on phone, donโt want to explain
best to look it up
donโt look for java examples
empty flint
@hot hull literally took me 2s to google mixin java ๐
hot hull
I looked it up Blocky yes. Confused by what the deal is here now
empty flint
use a mixin-esque pattern with two interfaces
@quiet depot That was my second idea that I haven't yet implemented and thought before I go and refactor shit I'd better ask if Kotlin has a better solution
lunar cypress
Elara: perfect in every way
What is this lmao
quiet depot
bmโs language
@empty flint idk, does kotlin have language level traits/mixins?
afaik it doesnโt
so doubt itโd be any better here
old wyvern
so mixin is like a function that isnt part of the actual object?
quiet depot
well the word โmixinโ describes it perfectly
old wyvern
mix-in
quiet depot
mixing functionality
lunar cypress
No not elara this meme
old wyvern
I mean would extensions be an example of that?
empty flint
internal abstract class <T> it is
quiet depot
technically yes yugi
old wyvern
hmm
empty flint
@empty flint idk, does kotlin have language level traits/mixins?
@quiet depot Comparable is a mixin.
So it does. Kinda
At least according to Google it is
I swear all of your questions are "how do I do this impossible hacky thing"
@prisma wave Hm do you mind that I ask dumbass questions where the answer is always something along the lines of "no and also why in the fuck would you ever need that"?
quiet depot
blocky the problem is if youโre asking these questions, youโre doing something wrong
prisma wave
What is this lmao
@lunar cypress good meme

android dev is kotlin right?

Using java for android apps will summon a horde of angry developers
old wyvern
you know borz, this would have worked out in Elara
type YourType => { firstThing (Foo) => Unit } || { secondThing (Foo) => Int }
Using java will summon a horde of angry developers
and im guessing android stuidos the way to go?
onyx loom
ig so
hot hull
Aj, sheesh I just downloaded AS as well
old wyvern
oi
quiet depot
surely everything android studio can do is possible in ij ult
empty flint
blocky the problem is if youโre asking these questions, youโre doing something wrong
@quiet depot But that's exactly the reason I ask them? If I did everything right, why would I be asking questions?
quiet depot
ik the other ides can be emulated in ij, as is a bit diff tho cuz google
old wyvern
Can it debug install properly straight onto the device?
quiet depot
so not sure
old wyvern
Not really sure
prisma wave
IJ has an android plugin which makes it literally android studio afaik
old wyvern
ah
onyx loom
lol
old wyvern
I swear Jetbrains have updates for their IDEs every week or something
prisma wave
Pretty much lol
old wyvern
Everytime I open toolbox there is always something to update
quiet depot
srp irl is too hard
obtuse gale
yo why did android stuido make a src/main/java when I told it im deving in kotlin ๐
old wyvern
quiet depot
why u got com and ult?
old wyvern
I had comm from earlier
onyx loom
damn com is taking up like 1gb of storage u should delete it!
old wyvern
meh
old wyvern
lemme check
quiet depot
probs about 1gb
obtuse gale
im immensely disappointed with AS
onyx loom
lol?
old wyvern
yup
obtuse gale
like wtf, making main/java when its a kotlin project
onyx loom
u just downloaded it 
hot hull
I mean if I can use IJ for android dev, Imma use it
onyx loom
ok nvm
hot hull
Why use another thing if this works
obtuse gale
AS has drag and drop shit doesnt it?
old wyvern
Yes
obtuse gale
surely ij doesnt have that
prisma wave
It does with the android plugin I think
obtuse gale
im doing something really stupid atm lol
old wyvern
I cant seem to come up with any ideas to work on to try this
onyx loom
@old wyvern does ij offer anything similar to that (like a design view in VS) with JFX / tornado?
quiet depot
pretty sure it does
old wyvern
mhm
quiet depot
you realise as is ij right?
old wyvern
SceneBuilder or something
Also I just realized Android Studio generated the kotlin classes inside the Java root
obtuse gale
thats what i was saying before lol
onyx loom
you realise as is ij right?
@quiet depot i mean yea but im too dumb to know where this stuff is
jovial warren
hey anyone here know how to create a set that is the complement of another set in Kotlin? (for enums)
what I mean by complement is a set that has none of the values that the other set has in it
old wyvern
just filter out the ones that is contained in the other set from the values array?
jovial warren
good idea
obtuse gale
Anyone know a good place to learn android dev stuff?

@jovial warren I don't see why it wouldn't
distant sun
Go to it's maven repo? @obtuse gale
ocean quartz
What does that annotation do?
Anyways try and see it
distant sun
Imagine if android wasnt using xml for design ๐ญ
obtuse gale
pretty epic when stuff doesnt work and theres no errors ๐
jovial warren
@ocean quartz @Component? it basically makes the class managed by Spring
it's Spring's component annotation
ocean quartz
Ah fair
obtuse gale
I think im going crazy lol , I cant decide what to do, i started by fucking around with android dev, now imma make a spring website hehe
jovial warren
lol
heady birch
Spring is a good skill I think
obtuse gale
hm yeah, this will actually be a nice way to learn, its basically
Registration/Login,
Admin must verify your account before you can access a page
heady birch
If you need anyhelp ust ask me
obtuse gale
yeah what shit do i need from here lol
heady birch
Web -> Spring Mvc & Spring session
Template Engine -> Whatever you want (probably thymeleaf)
Security -> Spring Security
SQL -> Spring Data Jpa & MySQL Driver
jovial warren
or SQL -> Exposed for Spring Boot (can be obtained separately)
heady birch
Oh yeah actually maybe if your using Kotlin
jovial warren
yeah, imo Exposed > JPA for Kotlin
obtuse gale
hm?
jovial warren
you familiar with JetBrains Exposed?
obtuse gale
alright ill stick with it just cos ive used it
jovial warren
just use what you're most comfortable with
obtuse gale
I heard bm mention a kotlin plugin or something so you dont have to give everything default values, where would I find that?
cos in past projects ive just added default params to everything so theres a no-arg constructor, which jpa requires im guessing
obtuse gale
is it this? kotlin("plugin.jpa") version "1.3.72" I just noticed thingo added it to my build.gradle.kts
jovial warren
maybe
heady birch
For login page make a plain html form
Registration forms look into thymeleaf object binding
Create a pojo e.g
class RegistrationForm {
String name, email, password, confirmPassword;
}
prisma wave
@obtuse gale if you've set it to use kotlin it should add the jpa plugin automatically
ocean quartz
This is awesome, the way commonmark handles the parser is pretty cool, just made the colors escapable
�This \&cis &r*Sparta* &cnot escaped
prisma wave
Hot
ocean quartz
Very hot, this means i can make it so formats can pass through nodes and possible even through lines, so you'd have like gradient that would follow up through all lines
onyx loom
or just dont have exceptions, ez
ocean quartz
Oh boy, <#hex> format also works, now the fun part, the complex <g:hex:hex> and <r:1.0:1.0> 
ocean quartz
@prisma wave @old wyvern Question for you guys about Elara's parser, how do you guys detect double/float?
I have a scanner, which is basically a Stack, it has all the characters, i need to peek into the stack and check the combination of them is a double or not if you know what i mean
prisma wave
iirc that should be done in the lexer
which basically just checks if a . is present at all
probably a naive solution, but it works
numType := Int
for {
ch := s.read()
if ch == eof {
break
}
if ch == '\n' {
s.unread()
break
}
if ch == '.' {
numType = Float
} else if !unicode.IsNumber(ch) {
break
}
buf.WriteRune(ch)
}
the f is :=
prisma wave
variable declaration
but with inference
var [name] [type] is for traditional declaration
name := value is for type inference
ocean quartz
Let me give this a shot, and yeah it's basically a lexer but commonmark calls it a parser for some reason
prisma wave
odd
distant sun
ugly
hot hull
Berry
prisma wave
never disrespect go like that
hot hull
I mean not bad?
ocean quartz
Well, works well
Daba dee daba die
Oh, found a problem lmao, if no closing character is found it'll loop forever 
May not be the best implementation but it's cool, all sorts of combinations work, like 1, 1., 1.0, 1.25, .2, etc
And this doesn't throw error xD
hot hull
What a comek Matt
ocean quartz
Comek?

Is that Go?
numType := Int

ch := s.read()
if ch == eof {
break
}
if ch == '\n' {
s.unread()
break
}
if ch == '.' {
numType = Float
} else if !unicode.IsNumber(ch) {
break
}
buf.WriteRune(ch)
}
I think is elara
heady birch
for ? {
distant sun
Or the parser for elara written in go
heady birch
Is that for a loop?
prisma wave
Not exactly
distant sun
while true
prisma wave
I think they function more like while true yeah

you know how gradle has smth like this for setters of an object?
options {
x = 1
y = 1

Is there an equivalent for kt?options.apply

instead of
options.x = 1
options.y = 2
