stdlib

The Kotlin Standard Library

This module creates the standard library for Kotlin.

Notes for contributors

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

These sources are placed into the generated folder and their names are prefixed with an 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 written in a special Kotlin-based DSL.
