Tuples-KT contains tuples from 4 (Tuple4) to 36 (Tuple36) arity, to make up for that Kotlin only has Pair and Triple.
Tuples are useful if you don't want to create a local type or class, as the name is "unnecessary" and we just want to combine a few values together without having to name the class. Works well in combination with decomposition.
val (someValue, otherValue) = pair
val (someValue, otherValue, anotherValue) = triple
val (someValue, otherValue, anotherValue, thatValue) = tuple4
...
val (a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z) = tuple26
...In order to use Tuples-KT, you need to add jitpack to your project root build.gradle.kts
(or build.gradle):
// build.gradle.kts
allprojects {
repositories {
// ...
maven { setUrl("https://jitpack.io") }
}
// ...
}or
// build.gradle
allprojects {
repositories {
// ...
maven { url "https://jitpack.io" }
}
// ...
}In newer projects, you need to also update the settings.gradle file's dependencyResolutionManagement block:
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven { url 'https://jitpack.io' } // <--
jcenter() // Warning: this repository is going to shut down soon
}
}
and then, add the dependency to your module's build.gradle.kts (or build.gradle):
// build.gradle.kts
implementation("com.github.Zhuinden:tuples-kt:1.2.0")or
// build.gradle
implementation 'com.github.Zhuinden:tuples-kt:1.2.0'Copyright 2020-2023 Gabor Varadi
