let will return a nullable boolean so == true
winter iron
😦
but even so
?: will be fine here
if it returns null then i wanna default to false
if not will it not just return whatever is returned by let?
ocean quartz
Yeah, i just think == true is more readable, though that's preference
winter iron
thats true
alrdy gets weird with let
lets not make it aids
cooldowns[key] ?: 0
cooldowns.getOrDefault(key, 0)
🤔
i think default makes sense here
since i dont wanna deal with a null
ocean quartz
Get or default does exactly that
ocean quartz
Not really, it's one less call
Similar to Enum#equals it just returns enum == other
So instead is better to just do enum == other instead of calling equals

@all plugin devs: Are there any epic methods to promote Spigot plugins? I recently published my first. So far I've only shared it on spigotmc and polymart. How do I get the ball rolling?
old wyvern
wait.
ocean quartz
Small updates pushes your plugin up the recent list
obtuse gale
yeah updating is pretty important because of that
i made a plugin, published it on spigotmc, kept it up to date for some time very frequently and it got like uh idk how many few thousand downloads lmao
i don't regret it
but
🥲
old wyvern
lol
quaint isle
I suppose keeping an eye on r/admincraft and spigot forums won't hurt either, maybe I can suggest the plugin every now and then
I already published two updates (~3 days apart), guess I keep doing that for a while until I got a smol userbase.
Is it worth putting some SEO effort in the spigot description in order to get some organic traffic in from Google?
old wyvern
Um, is it me or does IntelliJ's embedded scene builder not render css updates?
obtuse gale
wow the one single time I'm using kotlin
it lets me down
this is extremely disappointing
cinder flare
wdym
obtuse gale
if you ever worked with regex patterns and match results etc, you'll know that you can make "groups", kinda like "sections" you can get out of the match result
so for instance \\d(\\w) will match any single digit + any single alphanumeric character, the () is grouping the match inside of it so I can "extract" it, result.group(1) (0 is the entire match, 1 first group, 2 second group, etc)
cinder flare
so kotlin and java don't have a way to get the groups?
obtuse gale
yeah yeah they do
but
I was expecting something like match[1] to get the first group
kinda like how you access a map or a list
but nooooo
i need to add that myself
old wyvern
Doesnt that already work?
old wyvern
I was expecting something like `match[1]` to get the first group
Are you using kotlin's regex or java's?
obtuse gale
kt
old wyvern
val res = "\\d(\\w)".toRegex().find("1w")?.groupValues ?: return
println(res[1])
This seems to work
obtuse gale
eeee not exactly what I want
old wyvern
oh rip
obtuse gale
because that's a list if i'm not mistaken
old wyvern
yea
cinder flare
i mean what else would it be

cinder flare
man this kotlin thing is getting better and better
old wyvern
its on spigot as well
cinder flare
paper too?
onyx loom
😭
old wyvern
yes, paper has everything spigot does
cinder flare
until the hard fork >:)
old wyvern
Probably wont change things instantly
They would end up with too many broken plugins
What would be the best way to setup a layout like this?
cinder flare
they should definitely like get a bunch of people to sign on and like prepare their plugin for paper only compatability
uh definitely a grid setup with like bootstrap
css also has its own but it's a lot less good
old wyvern
Its javafx star
old wyvern
I tried with stackpanes and ended up with this shit
cinder flare
javafx has a grid system
old wyvern
Yes, but I probably shouldnt have have multiple inner ones
old wyvern
I tried with stackpanes and ended up with this shit
That is already in a grid pane btw
cinder flare
well surely that could all be in one grid, just have the top row be like 7 - 5, second row be 4 - 4 - 4, bottom be like 4 - 8
old wyvern
old wyvern
I tried with stackpanes and ended up with this shit
This is what you're looking at in this image
old wyvern
well surely that could all be in one grid, just have the top row be like 7 - 5, ...
Im not sure if they would line up properly when text wraps
cinder flare
they really don't go next to eachother? that is so weird
well you just extend the height of the row
old wyvern
wdym?
cinder flare
like they should always be that width, but if there's like a whole paragraph in there just wrap it and make it taller
old wyvern
You meant a fixed width right?
cinder flare
well like, it changes based on percent right
old wyvern
Thats how its set rn
cinder flare
so you have the overall grid that takes like 80% of the screen
then the boxes inside all have a number or percent, bootstrap does 12
so then if you make it smaller it makes the middle bits smaller and eventually stacks them
cinder flare
well it's weird that it doesn't work how I'd think it should
old wyvern
The problem is the table-cell like area
ocean quartz
I love you
A fun thing, wouldn't apply to this case but pretty useful
val regex = "(?<example>\\d+).(?<second>\\d+)".toRegex()
val (example, second) = regex.matchEntire("5.5")?.destructured ?: return
example.toInt() // now 5 as int
second.toInt() // now 5 as int as well

i like to use procyon where cfr miserably fails
but last time I checked, you really can't use procyon on an entire project
frail glade
FishSlapper says otherwise
old wyvern
I ussually just throw the jar into here http://www.javadecompilers.com/
quiet depot
I tried to use procyon for a commission once and the code it generated from the bytecode was just plain wrong
semantics were different
it's fine for quickly looking at shit
but I wouldn't use it to decompile a project to work on
old wyvern
I got GangsPlus working with that

If all of your plugin's code isn't from Google, you're doing it wrong.

they all have flaws

does this thing which is correct by spec but i mean lmao
quiet depot
from my experience I've found cfr & procyon to be the best mix
old wyvern
how do you mean mix?

you use cfr for the base project
then anything cfr fails on, or doesn't look quite right
you use procyon on

there must be a better way to do this in Kotlin
I also only kind of understand what's happening
is that basically converting the json into a Set of Maps of String and Any?
quiet depot
u using guice in that project?
cinder flare
not yet
quiet depot
well
when you do
Types.setOf(Types.mapOf(String.class, Any.class))
alternative to typetoken
cinder flare
That's a guice function?
cinder flare
well yeah but like earlier I just bound it to a cute little data class
is there no way to like, do the same thing with Sets and Maps?
old wyvern
is that basically converting the json into a Set of Maps of String and Any?
No, converts json to a map and iterates over its entries
cinder flare
val profile = gson.fromJson(content.toString(), MojangUUIDProfile::class.java) look at that!
cinder flare
No, converts json to a map and iterates over its entries
well yea yea I got that
cinder flare
it converts it to a set of maps
old wyvern
I think you were right
cinder flare
and iterates over that set
old wyvern
Yes
cinder flare
but is there no cute :: way of writing that?
cinder flare
i can barely read that on pc
cinder flare
quiet depot
no star because class instances don't hold runtime type parameters
quiet depot
yes
cinder flare
😮
old wyvern
The type token is a nice hack to overcome type erasure
cinder flare
it's really ugly though
cinder flare
maybe I'll just get guice and do that piggy thing

this looked 10x worse in java

are you saying you're a fan of this

cinder flare
I'll auto close you
quiet depot
the cast is necessary
old wyvern
Cant the type in the parameter be that?

no, because he calls .type which returns a java Type

this is what I meant btw pig fromJson<Set<Map<String, Any>>>
instead of using Any and casting

You could probably extract the typetoken part to a separate function
cinder flare
I mean is there really no way to get around that horribleness
quiet depot
bruh
old wyvern
I mean is there really no way to get around that horribleness
inline fun <reified T> typeOf() = object : TypeToken<T>() {}.type```.
cinder flare
oh yea I forgot about Guice
lemme get that
content = reader.lines().reduce { acc, line -> "$acc\n$line" }.orElse(null) this line will slap em all together separated by newlines or if there's nothing there it'll be null right
jovial warren
there's a library called Kotlin Guice that adds these sorts of things to Guice
and I made my own extensions library for Gson that has these sorts of reified thingies

Kotlin Guice!

why arent you just memory caching this?

also how would that change anything
this function would still need to exist to get the stuff to cache in the first place

not true its just a uuid and a string lol

content = it.lines().reduce { acc, line -> "$acc\n$line" }.get()
}
return gson.fromJson<Set<Map<String, Any>>>(
content,
object : TypeToken<Set<Map<String, Any>>>() {}.type
).map { it["name"].toString() }
}
}```okay how's that
potent nest
well that'll throw an exception if lines() returns an empty stream
cinder flare
well how do I not do that
potent nest
also there's .collect(Collectors.joining("\n"))
cinder flare
uh, doesn't seem so
potent nest
that's java api
cinder flare
please keep in mind I am doing all this functional stuff for the first time in Kotlin 🙂
distant sun
Doesnt lines() return a collection?
cinder flare
returns a Stream
distant sun
Ah
cinder flare
fun getPlayerNameHistory(pName: String): List<String> {
if (!ProxyServer.getInstance().config.isOnlineMode) {
throw RuntimeException("Can't get player name history from an offline server!")
}
// Fetch player's name history from Mojang servers
val url = URL("https://api.mojang.com/user/profiles/${Core.getUUID(pName)}/names")
with (url.openConnection() as HttpURLConnection) {
inputStream.bufferedReader().use { response ->
return gson.fromJson<Set<Map<String, Any>>>(
response.lines().reduce { acc, line -> "$acc\n$line" }.get(),
object : TypeToken<Set<Map<String, Any>>>() {}.type
).map { it["name"].toString() }
}
}
}```okay how bout that
quiet depot
still not using types util
cinder flare
also will that return an empty list if it doesn't succeed in any of those
yeah gettin there
distant sun
The one with $$?
quiet depot
ye
distant sun
bs
cinder flare
hey will that return an empty list or whatever it succeeds with?
cause I don't have another return...
distant sun
Most likely no
cinder flare
so why is it okay with me not having another return lol
distant sun
Kotlin doesnt force you to use try / catch
obtuse gale
```kt
inline fun <reified T> typeOf() = object : TypeToken<T>() {}.type```
this will work too btw....
for your type
cinder flare
wait why the fuck does this function throw a runtime exception
shouldn't it just like... return an empty list or something
old wyvern
Star, use reduce with the 2 args
Use an empty string as first arg
No need to use the optional version here
cinder flare
isn't that already reduce with the 2 args?
old wyvern
What are you confused about?
cinder flare
how to change my function to the one you said
I have literally the slimmest idea of how these work
i just copied from the kotlin examples page
old wyvern
Just add that emoty string argument like I showed above
cinder flare
k and then
old wyvern
And then remove the get()
cinder flare
ahhh I see
old wyvern
Because this one returns T instead of Optional<T>
cinder flare
Oh that's nice!
ah cause it'll just return an empty string if it doesn't have anything in it
now that's smart
old wyvern
Not an equivalent for a default btw
Its just what the initial value of acc will be
The identity value for your operation
cinder flare
well yea but if there's no elements in it, it'll just return whatever I pass in first right?
old wyvern
Mhm
old wyvern
yeah okay so sounds like a default
But a change in that string will affect your output string
This might still add an extra line to your output tbh
old wyvern
You could move the \n to the end of the string and trim at last
cinder flare
well hmm
to try it I have to do a lot more lol
can I just execute this script by itself
how do those kotlin scripts work lo
old wyvern
I just test on kotlin playground normally
cinder flare
kotlin playground don't have the type shit
old wyvern
Oh right gson
cinder flare
well I guess let's trial by fire it
prisma wave
How come you're not using Collectors.joining
cinder flare
because it's a Stream
old wyvern
Collectors.joining is used in a stream
old wyvern
Wait did you just want to join by newline?
potent nest
that's why I mentioned it before
prisma wave
😵💫 😵💫
old wyvern
Reader#lineSequence().join("\n")
joinToString*
old wyvern
^
quiet depot
what r u tryna do
cinder flare
I'm not entirely sure tbh
quiet depot
pls no make me scroll up
old wyvern
Is response a BufferedReader?
cinder flare
yes
prisma wave
doesn't kotlin also have reader.readAllText or something
old wyvern
Then ok
cinder flare
man see this is why I got the Genius Bar here
imagine what I'd be doing without you guys
quiet depot
writing bad code
obtuse gale
why did you switch it to kotlin?
cinder flare
cause I think its pretty and nicer than Java
obtuse gale
jw idc if youre doing it to learn, i do not recommend pasting java code in then converting tho cuz it makes it aids
cinder flare
well this entire plugin is in Java
and is moderately poorly written
so I figure converting it to Kotlin then fixing it up real nice file-by-file is a pretty good solution for all the small parts
then when it becomes more manageable, I plan on implementing Guice and other niceties project-wide
plus look at how much I'm learning about streams and stuff!
okay well guys it worked perfectly
thank you all for your support ❤️
obtuse gale
gg, kotlin you dont have to use streams so often prolly unless you prefer them over kt sequeneces
cinder flare
are sequences the collection operations
cause I would like to use those a lot more, it's just that this is a Java stream boi
prisma wave
Nah sequences are a distinct thing
They're lazy rather than eager
Similar to streams
cinder flare
how would I go about using those
prisma wave
.asSequence()
obtuse gale
streams are pretty lazy as well tho yea
prisma wave
or sequenceOf()
prisma wave
Not particularly
Depends
If you have a big collection and / or lots of operations it might be worth converting to a sequence
cinder flare
okay I see
obtuse gale
love you bristy
prisma wave
Ily too
cinder flare
hey is RedisBungee like not a thing anymore
obtuse gale
ah just bridge it yourself
cinder flare
well this plugin had support for it like 5 years ago
so I'm just not touching it for a while lol
obtuse gale
lol jesus as long as it works
cinder flare
I am not sure if it works
I just am not touching it lol and the one person who wanted it does not use it so
we gucci
cinder flare
woah what
obtuse gale
were just intimate like that
cinder flare
dang yeah apparently
so this is a weird request but... is there an easy way to take that gson that's been mapped to a Map<String, Any> and use its values in a pretty string?
okay that's a weird one nevermind
but what about
val city = if (!(attributes["city"] as String?)!!.isEmpty()) attributes["city"] as String? else "unknown"```terser?
old wyvern
(attributes["city"] as? String) ?: "Unknown"
hey wait
old wyvern
oh empty
cinder flare
this JSON will only be strings won't it
old wyvern
one moment
cinder flare
why do I have a map of String and Any
old wyvern
idk lol
obtuse gale
thats probably what the conversion did
cinder flare
it's trying its hardest
obtuse gale
yea sometimes its handy
cinder flare
val city = if (attributes["city"].isEmpty()) attributes["city"] else "unknown"
that but condensed
how do
obtuse gale
make val attribute = attributes["city"]
cinder flare
what
I mean is there not a terser way of saying "if this condition, return this, otherwise return myself"
obtuse gale
not really thats kotlins way
cinder flare
hmmm
old wyvern
I mean is there not a terser way of saying "if this condition, return this, othe...
val city = attributes["city"].ifEmpty { "unknown" }
lol
cinder flare
There's a lot more querying of REST apis in this plugin than I thought there would be
this is the third time I've used that little Http script
old wyvern
retrofit?
cinder flare
what
old wyvern
for http requests
cinder flare
oh no the little thing we made earlier
val url = URL("http://ip-api.com/json/$ip?fields=country,countryCode,city")
with (url.openConnection() as HttpURLConnection) {
inputStream.bufferedReader().use { response ->
val attributes: Map<String, String> = gson.fromJson(
response.lineSequence().joinToString("\n"),
object : TypeToken<Map<String, String>>() {}.type
)
return """&7City: &f${attributes["city"]?.ifEmpty { "Unknown" }}&7
| Country: &f${attributes["country"]?.ifEmpty { "Unknown" }}&e
| (&f${attributes["countryCode"]?.ifEmpty { "Unknown" }}&e)""".trimMargin()
}
}```I mean is it really worth it for the 3 times I used it?
old wyvern
🤷
quiet depot
use java 11 http api
cinder flare
which would look like?
quiet depot
oof
cinder flare
pfft
cinder flare
lmao even you're not exempt from the pron
quiet depot
guess not
old wyvern
pron?
quiet depot
hub
old wyvern
Did he actually mean porn?
cinder flare
yes but I did not want to be censored
old wyvern
lol
quiet depot
lame
cinder flare
rules are rules
until you go add an exception to Barry, that is
well hang on now
mr BodyHandlers, that doesn't map it to a cute data class for me
cinder flare
I'll body handle you
cinder flare
okay so there actually is a cute little BodyHandler maker
but my brain is much too small to understand the type declaration or how I could map it myself
so that's a function that takes a ResponseInfo! and returns a BodySubscriber of some type?
cinder flare
fun getUUID(pName: String): String {
val request = HttpRequest.newBuilder()
.uri(URI("https://api.mojang.com/users/profiles/minecraft/$pName")).build()
val response = httpClient.send(request, BodyHandlers.ofString()).body()
return gson.fromJson(response, MojangUUIDProfile::class.java).id
}```this is the final formm
cinder flare
good shout tho
quiet depot
looks like shit but i’m on phone
sly sonnet
Didn't you have to use {$pName}?
sly sonnet
Ah, now I see
cinder flare
val isEnabled = when (module) {
is BanConfig -> module.config.get(BanConfig.ENABLED)
is MuteConfig -> module.config.get(MuteConfig.ENABLED)
is CommentConfig -> module.config.get(CommentConfig.ENABLED)
is KickConfig -> module.config.get(KickConfig.ENABLED)
else -> false
}```damn is that beautiful or what
this could be Java some day
like, around september actually
old wyvern
Any reason module itself doesnt just expose a isEnabled method?
cinder flare
uhhh
cause I'm silly and just stapled on MF-CFG
the old cfg framework used inheritance, so it was just a single method to get any of the enabled states
but that is an excellent suggestion sir
cinder flare
you... don't like pattern matching switches?
prisma wave
That definitely breaks some principle / guideline
No you should be doing what yugi said
old wyvern
Kotlin bad?
old wyvern
gn
old wyvern
yea?
prisma wave
Do you know of a nice way of handling errors in haskell
MonadFail isn't really what I want
old wyvern
Either
old wyvern
I think thats what libraries commonly use atleast
prisma wave
what if there could be multiple errors?
steel heart
I think I started to understand what a monad is
prisma wave
nice
basically i am writing a math parser but obviously there will be certain things that don't work (dividing by 0, referencing variables that aren't bound, etc)
old wyvern
Hmm
prisma wave
class Evaluate t where
evaluate :: Context -> t -> Either Double String
``` have done something like this so farnot sure if that's the best option though
and then we can implement it with something like this: ```hs
instance Evaluate Expression where
evaluate context (VariableExpression name) = variables context M.!? name
Is Stream#flatMap a monad or no?
prisma wave
Stream is
old wyvern
try something like this maybe
data ParseException = DivisionByZero | UnboundVariableAccess | ...
class Evaluate t where
evaluate :: Context -> t -> Either Double ParseException
Oh pog
prisma wave
ooh that is a good idea
old wyvern
Is Stream#flatMap a monad or no?
flatMap is equivalent to a bind
steel heart
old wyvern
mhm
prisma wave
hmm
steel heart
mmh
prisma wave
now how to get nice error messages that show where the error occurred
i guess just have ParseException take a String too
and worry about that later
ooh i wonder if i can just store the Expression that caused the error
prisma wave
lol
