can’t you just introduce another variable for T?

then the functions wouldn't be accessible outside of a do block

jovial warren
why does binary compatibility matter exactly
binary compatibility is the ability to take already compiled code and use it with an existing system
so e.g. when the API reaches 1.0, you'll be able to use 1.0 compiled code on say 1.35 and it'll still work normally
cinder flare
why would you not recompile
jovial warren
¯_(ツ)_/¯
cinder flare
that is not a good reason to stop using amazing language features

maintaining binary compatibility is a very important thing for public APIs though anyway

you increment the major version, because you made backwards incompatible changes

jovial warren
I dont think theres really a major issue with how kotlin handles it
the componentN and copy functions are where everything breaks

In fact, despite Java's binary compatibility features, I recommend frequent recompilations anyway, since other features of Java do a great job of letting the compiler spot bugs for you.
point deleted
i will continue using kotlin data classes thank you very much
jovial warren
I'm not saying that you shouldn't recompile when something is updated

I mean, there is ofc a limit
cinder flare
i don't see why changing the copy function would break anything
jovial warren
because you're changing the signature of the function Star
cinder flare
the copy function takes nothing and returns a new copy of the object
it's the same no matter which parts of the object there are
jovial warren
not true
ocean quartz
Just update your stuff, if people choose not to, it's their problem
jovial warren
I think you're confusing copy with clone Star
obtuse gale

cinder flare
oh huh

It takes all properties of the data class as optional params
cinder flare
well still, if they're updating your api they better be ready to fix some bugs
people can stay on legacy versions if they don't want to update
jovial warren

yeah I'm not saying we won't update, I'm just saying I don't want to end up on major 173 just because I made another tiny binary incompatible change

Sir, this is dev general
oh umm then where should i ask
cinder flare
Sir, dev general is this
jovial warren
if you add a new field in the middle of the data class, the componentN function should return the value for the position of that argument
jovial warren
e.g. kotlin data class Person(val name: String, val age: String) component1 returns name and component2 returns age
prisma wave
#mc-server-general is definitely the right channel
old wyvern
xD
jovial warren
now, say if I add a new field in the middle of that, component2 should return that new field
prisma wave
e.g. ```kotlin
data class Person(val name: String, val age: String)
``` `compone...
data Person = Person { name :: String, age :: String} 😌
jovial warren
having that new field at position 2 be returned by component3 would kinda break the contract of the component functions
cinder flare
`data Person = Person { name :: String, age :: String}` 😌
struct Person {
name: String,
age: i32,
}```😌
jovial warren
I'm not saying you shouldn't use data classes, I'm saying you should exercise caution when using them in public APIs
ocean quartz
Or use them and don't care
jovial warren
well yeah, if you wanna break binary compatibility every time you add a new property and piss of developers, sure
cinder flare
this is why you have major releases
prisma wave
okay kotlin has introduced a major technical limitation
i dont think there is a fix for this
jovial warren
this is why you have major releases
yeah but you shouldn't be incrementing your major every time you add a new field to a class

I'd probably create a permissions table then when you need to add a permission to a user add the id instead of the permission directly
cinder flare
what are you storing complicated permissions in a database for is my question
obtuse gale
wdym
cinder flare
what permissions are you storing that need to be in a database
obtuse gale
I'd probably create a permissions table then when you need to add a permission t...
wont that just complicate things? Then if i wanna add a new perm i have to add it in the database instead of just adding a stirng to someones profile
obtuse gale
what permissions are you storing that need to be in a database
like what can be accessed and whatnot, but its for multiple different applications, so
cinder flare
Well what Matt said is just general relational database design
sounds like you could solve this with booleans
ocean quartz
That'd be the opposite, adding just a string to someone's profile will turn into a spaghetti in no time
obtuse gale
hm i see
but once the apps built the perms table wont change at all
since no new perms will need to be added
obtuse gale
true ig
so the user would have a list of ints or longs or whatever thats all the IDs of the perms they have?
cinder flare
yeah why use a relational database if you're not gonna design for a relational database
obtuse gale
yeah

@lunar cypress I remember the other day, we were discussing comparing vectors (which requires comparing floating point values too), and I'm using a fuzzy equals (absoluting the difference and checking against an epsilon value), but I was just wondering: what kind of hashCode should I write for this? because I don't think I can really fulfil the equals contract here using a fuzzy equals
current equals: ```kotlin
override fun equals(other: Any?) = other is Location &&
world == other.world &&
abs(x - other.x) < EPSILON &&
abs(y - other.y) < EPSILON &&
abs(z - other.z) < EPSILON &&
abs(yaw - other.yaw) < EPSILON &&
abs(pitch - other.pitch) < EPSILON
We discussed that too, remember?
I think there is no solution
As soon as you introduce floating point numbers you break the contract
jovial warren
yeah
lunar cypress
If you want your thing to be practical
jovial warren
so what should I settle for then? something like kotlin override fun hashCode(): Int { var hash = 3 hash = 19 * hash + world.hashCode() hash = 19 * hash + (x.toRawBits() xor (x.toRawBits() shr 32)).toInt() hash = 19 * hash + (y.toRawBits() xor (y.toRawBits() shr 32)).toInt() hash = 19 * hash + (z.toRawBits() xor (z.toRawBits() shr 32)).toInt() hash = 19 * hash + yaw.toRawBits() hash = 19 * hash + pitch.toRawBits() return hash } ? (which is what Bukkit uses for Location)
lunar cypress
I have no idea
jovial warren
(x.toRawBits() is basically the same as Double.doubleToLongBits(x) btw)
I think that calculation is what's used by java.lang.Double#hashCode
half harness
so what should I settle for then? something like ```kotlin
override fun hashCode...
what is hashCode used for?
jovial warren
generating hashed representations of objects
steel heart
Dkim rly
jovial warren
and that hash is used in things like maps and lists to store values iirc
cinder flare
what is hashCode used for?
see if object is the same as other object
jovial warren
that's equals
lunar cypress
no
half harness
but what about #equals?
jovial warren
lol
jovial warren
hashCode generates a hashed representation of the object
cinder flare
which you can use to test for equality
lunar cypress
yesn't
jovial warren
you can, but you generally don't
cinder flare
well that's what like file hashing is for
i mean you wouldn't use that like, in your program probably, that's why #equals exists lol
lunar cypress
The reason you hash files is because it's a lot more efficient
jovial warren
Tom Scott once described a hash as "a summary of data"
and that's basically what it is
old wyvern
equality wont really hold since collisions can happen
lunar cypress
But every hash function has some form of collision so when you have equals, you don't use hashCode for comparison
jovial warren
^
cinder flare
okay
but what about validating you downloaded the right file with an md5 hash
other hash algorithms are available
cinder flare
yeah but it's hashing right
jovial warren
yes
old wyvern
Yea
cinder flare
see, i knew I was talking about something
jovial warren
and if the algorithm is strong enough then it's pretty good for comparisons
but a hash isn't just for checking equality
lunar cypress
it's for checking integrity because universal hashing algorithms have the property that if you flip a single bit, the resulting hash is vastly different
jovial warren
for example, your passwords that you enter into most websites are hashed, but that's not for checking equality
cinder flare
for example, your passwords that you enter into most websites are hashed, but th...
hashed and salted 😉
old wyvern
salted and hashed
lunar cypress
It should be noted that although md5 is shit and shouldn't really be used for anything, you get values that are much longer from it
than hashCode()
cinder flare
salted and hashed
well no definitely not in that order
lunar cypress
hashCode() is just int
old wyvern
Isnt it salted before being hashed?
jovial warren
yeah hashCode is limited to like 4 billion values
jovial warren
Isnt it salted before being hashed?
yes
old wyvern
Thats what I have read about it star
jovial warren
the salt is just text that's used to get more randomising out of the hashing function
old wyvern
Havent really implemented it anywhere so 🤷
lunar cypress
Isnt it salted before being hashed?
bet most websites do not hash and salt properly
jovial warren
oh most definitely
old wyvern
Are there no general libraries for this?
lunar cypress
there are
old wyvern
So people just ignore them?
old wyvern
yooo you could make a hash function in haskell
😌
lunar cypress
php exists kekw
cinder flare
php exists kekw
oh no
lunar cypress
I think that has a top level md5 function that people have been rolling with for several years
even though now it has password_hash or something too

What happens if a project have two libs as implementation dependency, one require (e.g.) Guava 18.0.0, and the other require Guava 27.0.0, what version will be picken up by gradle? And what happens if I specify Guava as explicit dependency (e.g. version 30.0.0), will Gradle yeet the versions required by both libs?
steel heart
Weird shit happens, Idk but I think at runtime it can cause NoSuchFieldError, NoSuchMethodError and possibly LinkageError

what name is better, setStringList, setStringCollection, setList, or setCollection for this method (yes I know it's not technically a List)?
cinder flare
i like setStringList
since it only allows Collections of strings right? so unless you make a generic setCollection, that name would be wrong
gusty glen
since it only allows Collections of strings right? so unless you make a generic ...
yes, the idea is that you can pass either a set or a list to the method, since it doesn't matter since they're going to be written on the file as many entries anyway
steel heart
setStringCollection ?
