Instead of writing many different files and serializing this "virtual file system" to a byte array in a protobuf message, just write the needed stuff directly, as fields in the Library message. Make it consist of many Part messages, where the Part message is equivalent to the BuiltIns message in builtins.proto. The next step would be to combine Library.Part and BuiltIns, which will allow us to simplify some serialization-related code soon. In this commit, no changes happened to the .kjsm format. But since the code that serialized the abovementioned files was shared, a temporary abstraction over two serialization formats was made, see SerializerCallbacks. This commit temporarily breaks .kjsm decompiler and stub builder
JavaScript Translation
This module performs the translation of Kotlin source code to JavaScript.
There are various Kotlin APIs to JavaScript environments and libraries in the js.libraries project.
Compiling the standard Kotlin library to JavaScript
- the kotlin-js-library module creates a jar containing all the Kotlin source code for the runtime and standard kotlin library code (both definitions and implementation code) to be compiled to JavaScript.
- the kotlin-js-tests module then compiles a selection of test cases from the Kotlin standard library for the JVM to JavaScript. These tests can then be run in a web browser using QUnit
- the kotlin-js-tests-junit then runs the JavaScript tests for the standard library inside JUnit using Selenium and the underlying JavaScript & QUnit so that the JavaScript can be tested as part of the maven continuous integration build.
Reusing JVM based test cases in JavaScript
Any Kotlin test cases using the org.junit.Test annotation and the kotlin.test package, such as this test case are automatically converted to JavaScript using QUnit.
This allows the test cases to be ran directly in a web page in any web browser.
Using the Kotlin Library in JavaScript
There is a simple sample which shows how to use the Kotlin Standard Library from inside JavaScript in a web page or in a JVM using kool.io's JavaFX browser
Contributing
We love contributions! The JavaScript translation could really use your help! If you fancy contributing:
- check the contributing section on general stuff like getting the code etc
- here's the list of current excluded standard library unit tests from the JavaScript JUnit test run; see if you can fix one of those? (Check the TODO commands and the links to specific issues)
- try fix one of the pending JavaScript translation issues
