pattern matching makes maybe monad a work of art

I hope they find a nice way to bring pattern matching with optional too
prisma wave
They'd better

Pattern matching sealed classes π€€
potent nest
Because pattern matching is epic
jovial warren
isn't Java's pattern matching basically ported when?
ocean quartz
Haskell 
potent nest
Probably my favorite Haskell feature
potent nest
isn't Java's pattern matching basically ported `when`?
No, when is poor manβs pattern matching
prisma wave
isn't Java's pattern matching basically ported `when`?
I'd argue when technically isn't pattern matching
There's only one pattern you can match
jovial warren
show me the difference
jovial warren
There's only one pattern you can match
wat
prisma wave
the only thing when can match is booleans
jovial warren
not true...?
prisma wave
Pretty much true
jovial warren
when can match anything
potent nest
potent nest
It takes the first branch that evaluates to true
prisma wave
mhm
jovial warren
ah
prisma wave
Proper pattern matching is about matching the structure of objects
ocean quartz
Deconstructed is probably the only true pattern matching in Kotlin
jovial warren
you mean destructuring?
prisma wave
right back at pc now
obtuse gale
i.e. when is just a bunch of chained if else's π
jovial warren
yeah
prisma wave
case someFunctionThatReturnsAMaybe of
Just value -> putStrLn value
Nothing -> putStrLn "Function did not return a value"
this is a pretty basic example
jovial warren
that literally looks like a when
gusty glen
i.e. when is just a bunch of chained if else's π
when using when if less than 3 members (if I'm not mistaken here), it's compiled to if else, otherwise it is compiled to a switch statement
prisma wave
but i'd like to see when do that, in it's current state
the closest you could get is smart casting
when (val res = someFunction()) {
is Just -> println(res.value)
is Nothing -> println("no value")
more noise, and an extra variable
what else
you can pattern match lists too
potent nest
smart casting was a fault, change my mind
gusty glen
@prisma wave arrow-kt β€οΈ ```KT
val someValue: Option<Double> = Some(20.0)
val value = when(someValue) {
is Some -> someValue.value
is None -> 0.0
}```
jovial warren
that actually looks kinda nice ngl
prisma wave
not bad
jovial warren
the arrow one
prisma wave
although still noisier
jovial warren
close enough
obtuse gale
anyone into MERNING
jovial warren
wat
gusty glen
you can also use fold to pattern matching KT Some(3).fold({ 1 }, { it * 3 })
potent nest
I mean the Maybe monad is basically the easiest, but Haskell allows way more pattern matching
old wyvern
It also cant do further constructor matching
prisma wave
I mean the Maybe monad is basically the easiest, but Haskell allows way more pat...
yeah maybe monad is just scraping the surface
jovial warren
you can also use `fold` to pattern matching ```KT
Some(3).fold({ 1 }, { it * 3 }...
why is the initial there a function?
old wyvern
Even assignment is pattern matching in erlang
jovial warren
it should be fold(1) { acc, it -> acc += (it * 3) }
prisma wave
reverse l = case l of
[] -> [] -- reverse of empty list is empty list
[a] -> [a] -- reverse of single element is single element
(a:xs) = reverse xs ++ a -- head:tail turns into reverse(tail):head
list pattern matching in haskell
yeah ik guards
potent nest
I prefer multiple function declarations over case of
old wyvern
{message, Value, Id, {to, Uid}} = MyMsg
This would match MyMsg against the left structure and assign variables as they match,
So it would capture, Value, Id and Uid
gusty glen
why is the initial there a function?
what do you mean with initial there?
old wyvern
This also matches objects in them tho
jovial warren
you put { 1 }, which is a function secretx
prisma wave
yeah
gusty glen
you put `{ 1 }`, which is a function secretx
.
old wyvern
Destructuring cannot really match
gusty glen
yes
jovial warren
why don't they use the normal Kotlin fold style?
gusty glen
it's a default value in case the Option is None
old wyvern
```
{message, Value, Id, {to, Uid}} = MyMsg
```
This would match MyMsg against t...
This itself matches 2 atoms
jovial warren
ah
gusty glen
because the idea behind functional programming is laziness, all values must only be computed if needed, hence why 1 is a lambda (lazy supplier)
there's a lot of extension functions to work with nullables etc
jovial warren
maybe Krypton should use arrow and become more functional
prisma wave
structuring things functionally is hard
old wyvern
ErLang also does the "No Errors at Runtime" very differently even tho its functional
prisma wave
without experience
gusty glen
jovial warren
I'd rather use Arrow than switch to Haskell lol
prisma wave
obviously
old wyvern
Its way is to simply crash the process if any slight thing goes wrong
prisma wave
lmao
old wyvern
And spin the process back up
Yup
Its built to crash
Quite literally
But the entire application continues
ErLang processes are lightweight
prisma wave
that's like haskell's do notation, quite nice

man, the new sealed interfaces are pog
I'm using them in the new Krypton command system I'm designing (which I totally didn't at all completely steal from Velocity)
jovial warren
there's going to be 3 types of commands:
- Brigadier command, which wraps a Brigadier
LiteralCommandNode - Legacy command, which is modelled after BungeeCord's command
- Raw command, which is useful for "bolting on" external command frameworks
raw command gives you the arguments as a single string, without any processing
legacy command gives you them as an array of strings (I'm using an array since most cross-platform plugins seem to use an array, and having to convert to a list is expensive)
I wonder if I should keep the legacy command as an abstract class that takes parameters though or make it an interface
probably the former tbh, since I find that easier to work with

what kind of text are we talking about here

lemme give an example wait

then i can just print that in 1 line in my main method
cinder flare
do you care about what text you send? or do you just want to send all of it in order?
gilded granite
because i don't want 90% of my code to be print's
it would be exact text in exact order
im using it to make GUI's in a console rpg
cinder flare
oh yeah so you can just use a text file, separate it by newlines, and use a scanner to read through it in order
gilded granite
okay, do you know any guides for doing that? im quite new to java
cinder flare
Scanner sc = new Scanner(new File("potato.txt"));
while (sc.hasNextLine()) {
System.out.println(sc.nextLine());
}```that should do it

actually it should be by lines

Current Gear:
Level 3 Sword
Level 11 Helmet
it just reads them in line order

oh btw, anyone wanna see my newly designed command system for Krypton?
I based it off of Velocity's
I've officially deprecated the old Command (renamed to LegacyCommand now) to encourage the use of its (kinda) replacement, BrigadierCommand
BrigadierCommand is a command that's backed by Brigadier's LiteralCommandNode
then the other addition is RawCommand, which is a command that has its arguments supplied as a single string, to allow external frameworks to do their own processing
talk about breaking changes though amirite
what's binary compatibility though? /s

half harness
```kt
fun main() = runBlocking { // this: CoroutineScope

also, what would be some alternatives to runBlocking?
since i think it creates the coroutine scope?
oh wait so runBlocking just runs, while blocking, but also creates a coroutinescope
so i'd assume theres something similar to runAsync {}?
prisma wave
runBlocking blocks
old wyvern
Inside a coroutine context you have async which exists for parrallel computation
prisma wave
also, what would be some alternatives to runBlocking?
Running in a scope / dispatcher
half harness
Running in a scope / dispatcher
if you run in a scope/dispatcher, it doesn't block?
old wyvern
If you dont want to execute skmething parallely just switch contexts with withContext where needed
cinder flare
hey Yugi
old wyvern
Hi star
cinder flare
remember that typescript thing
cinder flare
the data connector thing i was working on a month ago
prisma wave
if you run in a scope/dispatcher, it doesn't block?
Depends on the scope you use, but most are async yeah
cinder flare
yea
old wyvern
Yea?
cinder flare
i uh... need some more help
old wyvern
Sure

half harness
Depends on the scope you use, but most are async yeah
fun main() = runBlocking { // this: CoroutineScope
launch { doWorld() }
println("Hello")
}
// this is your first suspending function
suspend fun doWorld() {
delay(1000L)
println("World!")
}
```what exactly does the launch {} do? run async?In like 5 minute, not at pc rn
cinder flare
ah no problem, thanks in advance
prisma wave
```kt
fun main() = runBlocking { // this: CoroutineScope
launch { doWorld() ...
new coroutine
Because you're using runBlocking there's no benefit from using launch afaik
Unless you change contexts in doWorld
half harness
fun main() = runBlocking { // this: CoroutineScope
launch { doWorld() }
println("Hello")
}
// this is your first suspending function
fun doWorld() {
delay(1000L)
println("World!")
}
```if i removed the `suspend`, would it print ```
World!
Hello
```?it wouldn't compile
half harness
o
prisma wave
because delay is suspending
half harness
ah
fun main() = runBlocking { // this: CoroutineScope
launch { doWorld() }
println("Hello")
}
// this is your first suspending function
fun doWorld() {
println("World!")
}
```would it print ```
World!
Hello
```?ima be honest I think the coroutine library is really overcomplicated and hard to learn, so im not super familiar with how it works
jovial warren
```kt
fun main() = runBlocking { // this: CoroutineScope
launch { doWorld() ...
not necessarily
half harness
bardy's here!!!
jovial warren
you call launch, which launches a new coroutine
old wyvern
launch launches in the same context as a child
jovial warren
so that's gonna cause a race condition to see who can print the fastest
old wyvern
No bard
prisma wave
it's not a race condition if both are blocking
jovial warren
launch launches in the same context as a child
actually that is a good point
half harness
OH
jovial warren
launch isn't blocking though, is it?
old wyvern
There isnt a race condition here afaik
half harness
im barely understanding what yugi's saying
old wyvern
The oarent waits for the child
prisma wave
`launch` isn't blocking though, is it?
it launches in the runBlocking scope so yes, it is
old wyvern
The issue exists mostly for globalscopes
half harness
yugi u have to remember i have no idea what any of these are
jovial warren
does runBlocking use its own scope?
half harness
π₯²
jovial warren
didn't know that
half harness
fun main() = runBlocking { // this: CoroutineScope
launch { doWorld() }
delay(1000L)
println("Hello")
}
// this is your first suspending function
fun doWorld() {
println("World!")
}
```would it print ```
World!
Hello
```?yes
old wyvern
As long as you're launching in the same scope, it should wait for completion
old wyvern
Now say you are in scope A and you launch into GlobalScope, the job starts executing separately
half harness
launch = create new scope?
old wyvern
idk what scopes are
Scopes manage coroutine jobs
half harness
runBlocking = create new scope?
prisma wave
launch = new coroutine in the same scope
old wyvern
Every coroutine call you make, is split up into mutliple jobs for the scope by the compiler
prisma wave
runBlocking would kinda be the scope here
there's not an obvious one in this scenario
jovial warren
```kt
fun main() = runBlocking { // this: CoroutineScope
launch { doWorld() ...
I get the opposite results when using the Kotlin playground to fire that 1000 times
prisma wave
Yes because parent waits for child
half harness
kotlin playground?
jovial warren
half harness
Yes because parent waits for child
uh, what about #dev-general message tho
old wyvern
Parent jobs wait for child jibs
prisma wave
What about it?
jovial warren
because runBlocking is the parent here and launch is the child
and yet the println inside of the runBlocking runs before the launch code runs
so I get ```
Hello
World!
That's weird
jovial warren

Anyway coroutines overcomplicated and hard ExecutorService good coroutines bad

coroutines aren't that complex
half harness

prisma wave
We have already seen they're complex
jovial warren
contexts are a bit strange to understand, but they kinda make sense
prisma wave
i think the coroutines library is very overcomplicated
prisma wave
contexts are a bit strange to understand, but they kinda make sense
explain why hello world gets printed then, when parents are supposed to wait for children
jovial warren
you sure that launch gets executed under a child context here?
prisma wave
wat
jovial warren
what if it gets launched under the parent context and then happens to run after the println?
jovial warren
yeah ik that
half harness
idk i just think launch as create new coroutine
and since u create new one after, it runs after
but if you delay the first, the second runs
old wyvern
Then it works fine?
jovial warren
yeah those get executed sequentially since they're launched on the same scope and put into the same queue
jovial warren
what's the outcome of that?
jovial warren
who is the parent here though?
prisma wave
runBlocking
half harness
okay
jovial warren
yeah but how can the parent be waiting on the children if the parent gets executed first?
prisma wave
?
that's how coroutines work
it compiles to callbacks
Although probably not in this case
prisma wave
parent starts
suspends, waits for first launch call to finish
resumes
etc
parent finishes
jovial warren
yeah
old wyvern
yeah but how can the parent be waiting on the children if the parent gets execut...
Waiting as in the parent job doesnt end
the job is alive
jovial warren
ah
half harness
why is there apparently no main method for this: ```kt
import kotlinx.coroutines.*
fun main() = runBlocking { // this: CoroutineScope
launch { doWorld() }
launch { doHello() }
}
suspend fun doHello() {
delay(100L)
println("Hello!")
}
suspend fun doWorld() {
println("World!")
}
Waiting not in the blocking sense
jovial warren
I thought you meant waiting on the children to finish execution
that's usually what waiting in this context means
old wyvern
Now if you were to launch those into another scope, the parent would die befor the children
prisma wave
why is there apparently no main method for this: ```kt
import kotlinx.coroutines...
runBlocking returns the last call, launch {} returns a Job, so main returns Job<Unit> not Unit
old wyvern
This also means by cancelling the parent, you cant cancel the children
Another this is affects is exception handling
half harness
runBlocking returns the last call, launch {} returns a Job, so main returns Job<...
oh
jovial warren
Another this is affects is exception handling
english.exe not found
old wyvern
thing*
prisma wave
Add a return type*
jovial warren
@half harness just shove Unit at the end of runBlocking lol
old wyvern
another thing this*
jovial warren
adding a return type will cause you compile errors
prisma wave
adding a return type will cause you compile errors
Yes exactly
error is more obvious
half harness
import kotlinx.coroutines.*
fun main(): Unit = runBlocking { // this: CoroutineScope
launch { doWorld() }
launch { doHello() }
}
suspend fun doHello() {
delay(100L)
println("Hello!")
}
suspend fun doWorld() {
println("World!")
}
```this prints ```
World!
Hello!
so basically
jovial warren
fun main(): Unit = runBlocking { // Type inference failed. Expected type mismatch: inferred type is Job but Unit was expected
launch { doWorld() }
}
huh
idk it works for me tho
lol
maybe Unit is an exception?
jovial warren
```kt
import kotlinx.coroutines.*
fun main(): Unit = runBlocking { // this: Cor...
of course it does, since the launch calls are queued in order
half harness
ya
cinder flare
yeah Unit is like Object in java
old wyvern
Or should I say, everything extends Unit
half harness
of course it does, since the `launch` calls are queued in order

I can probably turn that off

thread.sleep sleeps the entire thread, delay suspends the coroutine and resumes it after the time has passed
half harness
i know that coroutines are different from threads
cinder flare
I can probably turn that off
you should do it then! that would make it okay in my book π
old wyvern
they both "sleep" the thread/coroutine
The difference would be that delay doesnt starve the thread
prisma wave
mhm
old wyvern
It schedules the continuation to be ran after that time and lets other jobs execute
half harness
so besides it letting other jobs execute
prisma wave
