KWasm is an Embeddable WebAssembly interpreter for the JVM
The primary goal of KWasm is to be a relatively lightweight, embeddable, WebAssembly interpreter for applications running in the JVM (or on Android). Beyond that, KWasm strives to:
- meet the latest current WebAssembly Specification's requirements,
- use minimal system resources,
- maintain WebAssembly's strict sandbox-like functionality, and
- support interoperation between Java/Kotlin code and the WebAssembly it is tasked with running.
Achieving good performance is a goal as well, but as with all interpeters: performance will never be as good as a compiled solution.
The primary benefit of interpretation over compilation is the capability for dynamic module loading & execution.
The development of KWasm will be done in a series of milestones:
- ✅ Implement text-based Wasm Parser Capability & AST-generation. (Completed 2020-01-01)
- ✅ Use the text-based Wasm Parser to develop/test the interpretation of the AST. (Completed 2020-12-23)
- ✅ Implement a binary wasm parser with AST-generation. (Completed 2021-01-07)
- Get all official spec tests to pass.
- Finalize API.
Prerequisites:
From the directory of your choice:
- Clone the repository to your local machine.
- Open IntelliJ/Android Studio, and Choose "New Project from Existing Sources"
- Select the
KWasmdirectory created in step 1.
That's it! The IDE will sync the project and you can begin working on KWasm.
You can run the entire test suite with:
