## Introduction
2018-10-11 19:29:36 +00:00
2018-12-06 07:04:19 +00:00
Wasmer is a Standalone JIT WebAssembly runtime, aiming to be fully compatible with Emscripten, Rust and Go.

## Usage
2018-11-05 13:52:53 +00:00
`wasmer` can execute both the standard binary format (`.wasm`) and the text
format defined by the WebAssembly reference interpreter (`.wat`).

## Building & Running
To build this project you will need Rust and Cargo.
```sh
# checkout code and associated submodules
2018-11-22 06:15:13 +00:00
git clone --recursive https://github.com/wasmerio/wasmer.git
2018-10-11 19:29:36 +00:00
cd wasmer
# install tools
# make sure that `python` is accessible.
cargo install
```

## Testing
2018-11-22 06:15:13 +00:00
Thanks to [spectests ](https://github.com/wasmerio/wasmer/tree/master/spectests ) we can assure 100% compatibility with the WebAssembly spec test suite.
2018-10-24 10:07:52 +00:00
2018-10-14 21:49:10 +00:00
Tests can be run with:
```sh
2018-11-15 21:30:00 +00:00
make test
2018-10-14 21:49:10 +00:00
```
2018-10-24 10:07:52 +00:00
If you need to re-generate the Rust tests from the spectests
you can run:
```sh
make spectests
```
## Roadmap
2018-10-14 21:54:28 +00:00
Wasmer is an open project guided by strong principles, aiming to be modular, flexible and fast. It is open to the community to help set its direction.
2018-10-24 10:07:52 +00:00
Below are some of the goals (written with order) of this project:
2018-11-22 06:15:13 +00:00
- [x] It should be 100% compatible with the [WebAssembly Spectest ](https://github.com/wasmerio/wasmer/tree/master/spectests )
- [x] It should be fast _(partially achieved)_
2018-11-22 06:12:34 +00:00
- [ ] Support Emscripten calls _(on the works)_
2018-10-24 10:07:52 +00:00
- [ ] Support Rust ABI calls
