[Wasmer](https://wasmer.io/) is a standalone JIT WebAssembly runtime, aiming to be fully compatible with Emscripten, Rust and Go.

_**NEW ✨**: You can now embed Wasmer in your Rust application, check our [example repo](https://github.com/wasmerio/wasmer-rust-example) to see how!_
Wasmer runtime can also be embedded in different languages, so you can use WebAssembly anywhere ✨:

* [**Python**](https://github.com/wasmerio/python-ext-wasm)
### Usage
Wasmer can execute both the standard binary format (`.wasm`) and the text
format defined by the WebAssembly reference interpreter (`.wat`).
Once installed, you will be able to run any WebAssembly files (_including nginx and Lua!_):

# Dockerfile Documentation
The `Dockerfile` included in the project root directory could be used for development purposes or to build a small image containing the `wasmer` executable.
The `wasmer-build-env` stage in the Dockerfile contains the dependencies needed to compile Wasmer including LLVM.
The `wasmer-debug-env` stage adds the `valgrind` profiling tool to the `wasmer-build-env` stage.
The `wasmer-build` stage in the Dockerfile will copy the current directory, assuming the build context is the `wasmer` project, and build the project using `cargo build --release`.
The `wasmer` stage will copy the resulting `wasmer` executable from the `wasmer-build` stage into a new base image to create a smaller image containing `wasmer`.
## Example Usages
### Wasmer image
1. From the `wasmer` project directory, build the image:
`docker build -t wasmer --target=wasmer .`
2. List options:
`docker run wasmer --help`
3. Mount a directory, and run an example wasm file:
`docker run -v /Users/admin/Documents/wasmer-workspace:/root/wasmer-workspace wasmer run /root/wasmer-workspace/examples/hello.wasm`
### Profiling
1. Build `wasmer-debug-env`:
`docker build --tag=wasmer-debug-env --target wasmer-debug-env .`
2. Mount a directory from the host and run interactively:
`docker run -it -v /Users/admin/Documents/wasmer-workspace:/home/circleci/wasmer-workspace wasmer-debug-env /bin/bash`
3. Inside the container, build `wasmer` and run profiling tool:
```
cd /home/circleci/wasmer-workspace/wasmer`
cargo build
valgrind --tool=callgrind --dump-instr=yes --collect-jumps=yes --simulate-cache=yes target/debug/wasmer run test.wasm
```
The `callgrind.out` can be viewed with the `qcachegrind` tool on Mac OS (`brew install qcachegrind`).

The wasm file `test_vfs.wasm` is generated by compiling the `test_vfs.c` and writing a tar.zst blob with a single file
named `data.txt`.
The program expects to find a file named `data.txt` and reads the contents and the file descriptor.
The runtime should mount the virtual filesystem and expose the file.
