The Kotlin Standard Library

This module creates the standard library for Kotlin.

Notes for contributors

We use some code generation to generate the various utility extension function for the various collection-like types like arrays, strings, Collection<T>, Sequence<T>, Map<K, V> etc.

These sources are placed into generated folder and their names are prefixed with the underscore, for example generated/_Collections.kt

To run the code generator use the following command in the root directory of the project:

./gradlew :tools:kotlin-stdlib-gen:run

Note: on Windows type gradlew without the leading ./

This then runs the script which generates a significant part of stdlib sources from the templates authored with a special kotlin based DSL.
