JSweet407

JSweet407 is a Java-to-JS transpiler implementation that builds upon Jsweet, adding support for Java concurrency features.

Key Components

JSweet407 consists of two main components:

1. Transpiler Extension
2. JS Multithreading Runtime

Supported Features

• Thread class
• Runnable interface
• synchronized keyword
• Thread methods from the standard library, such as:
  • join
  • sleep

Lock Classes

The current design architecture also allows for the easy implementation of various lock classes from the Java standard library. Examples implemented in the project include:

• ReentrantLock
• ReadWriteLock
• StampedLock

Documentation

The file technical-report.pdf in the root directory provides a detailed explanation of the project's design, architecture, implementation, and limitations, along with relevant data visualizations.

Demo Video

The example.mkv video file in the root directory demonstrates how to run this project using the compiled JAR package.

System Requirements

• JDK 16+
• TSC (TypeScript Compiler)

Usage Instructions

We provide a bash script run.sh to compile files and view the results.

• The script uses the precompiled JAR package in the artifacts directory to compile files from the example folder.
• Note: Only one file should be placed in the example folder at a time to avoid potential conflicts.
• During execution, run.sh stores intermediate compilation results in the tsout directory and copies the final compiled JavaScript code to runtime/src/compiled.js.

Users can view the execution results by accessing runtime/src/test.html through an HTTP server. For detailed steps, refer to the demo video example.mkv.

Testing Instructions

All test cases are located in the benchmark folder in the project root directory.
