[IR] Store preprocessed functions as private declarations

It is important to modify preprocessed inline functions to be
private. These functions are not supposed to be used anywhere.
Private declarations have a separate type of signatures.

If the signature remains public, then we can have clashes with
original functions. For example
1. Type parameter clash. If a type argument is used in the `typeOf`
call, then we handle it specially and keep it as is
(instead of erasure). This type argument must point to the type
parameter of the original function.
2. Reference to the inline function. If inside a preprocessed function
we have a reference to another inline function, then this reference
must point to the original one.

Kotlin Programming Language

Welcome to Kotlin!
Kotlin is a concise multiplatform language developed by JetBrains and contributors.

Some handy links:

Kotlin Multiplatform capabilities

Support for multiplatform programming is one of Kotlin’s key benefits. It reduces time spent writing and maintaining the same code for different platforms while retaining the flexibility and benefits of native programming.

Editing Kotlin

Build environment requirements

This repository is using Gradle toolchains feature to select and auto-provision required JDKs from AdoptOpenJdk project.

Alternatively, it is still possible to only provide required JDKs via environment variables (see gradle.properties for supported variable names). To ensure Gradle uses only JDKs from environmental variables - disable Gradle toolchain auto-detection by passing -Porg.gradle.java.installations.auto-detect=false option (or put it into $GRADLE_USER_HOME/gradle.properties).

On Windows you might need to add long paths setting to the repo:

git config core.longpaths true 

Building

The project is built with Gradle. Run Gradle to build the project and to run the tests using the following command on Unix/macOS:

./gradlew <tasks-and-options>

or the following command on Windows:

gradlew <tasks-and-options>

On the first project configuration gradle will download and setup the dependencies on

  • intellij-core is a part of command line compiler and contains only necessary APIs.
  • idea-full is a full blown IntelliJ IDEA Community Edition to be used in the plugin module.

These dependencies are quite large, so depending on the quality of your internet connection you might face timeouts getting them. In this case, you can increase timeout by specifying the following command line parameters on the first run:

./gradlew -Dhttp.socketTimeout=60000 -Dhttp.connectionTimeout=60000

Important gradle tasks

  • clean - clean build results
  • dist - assembles the compiler distribution into dist/kotlinc/ folder
  • install - build and install all public artifacts into local maven repository
  • coreLibsTest - build and run stdlib, reflect and kotlin-test tests
  • gradlePluginTest - build and run gradle plugin tests
  • compilerTest - build and run all compiler tests

To reproduce TeamCity build use -Pteamcity=true flag. Local builds don't run proguard and have jar compression disabled by default.

OPTIONAL: Some artifacts, mainly Maven plugin ones, are built separately with Maven. Refer to libraries/ReadMe.md for details.

To build Kotlin/Native, see kotlin-native/README.md.

Working with the project in IntelliJ IDEA

It is recommended to use the latest released version of Intellij IDEA (Community or Ultimate Edition). You can download IntelliJ IDEA here.

After cloning the project, import the project in IntelliJ by choosing the project directory in the Open project dialog.

For handy work with compiler tests it's recommended to use Kotlin Compiler Test Helper

Dependency verification

We have a dependencies verification feature enabled in the repository for all Gradle builds. Gradle will check hashes (md5 and sha256) of used dependencies and will fail builds with Dependency verification failed errors when local artifacts are absent or have different hashes listed in the verification-metadata.xml file.

It's expected that verification-metadata.xml should only be updated with the commits that modify the build. There are some tips how to perform such updates:

  • Delete components section of verification-metadata.xml to avoid stockpiling of old unused dependencies. You may use the following command:
#macOS
sed -i '' -e '/<components>/,/<\/components>/d' gradle/verification-metadata.xml
#Linux & Git for Windows
sed -i -e '/<components>/,/<\/components>/d' gradle/verification-metadata.xml
  • Re-generate dependencies with Gradle's --write-verification-metadata command (verify update relates to your changes)
./gradlew --write-verification-metadata sha256,md5 -Pkotlin.native.enabled=true resolveDependencies

resolveDependencies task resolves dependencies for all platforms including dependencies downloaded by plugins.

You can also use ./scripts/update-verification-metadata.sh script which includes both of these steps

Keep in mind:

  • If you’re adding a dependency with OS mentioned in an artifact name (darwin, mac, osx, linux, windows), remember to add them to implicitDependencies configuration or update resolveDependencies task if needed. resolveDependencies should resolve all dependencies including dependencies for different platforms.
  • If you have a local.properties file in your Kotlin project folder, make sure that it doesn't contain kotlin.native.enabled=false. Otherwise, native-only dependencies may not be added to the verification metadata. This is because local.properties has higher precedence than the -Pkotlin.native.enabled=true specified in the Gradle command.

Using -dev versions

We publish -dev versions frequently.

For -dev versions you can use the list of available versions and include this maven repository:

maven("https://redirector.kotlinlang.org/maven/bootstrap")
