Christoph Herzog 7d801491ed chore: Remove wasi-experimental-io-devices
This library was an experiment to provide a simple framebuffer API.
It does not currently compile, and has not done so for over a year.

Removing it reflects the fact that this will not be maintained or
updated in the future.

wasmer-cli Build Status Join Wasmer Slack MIT License

This crate is the Wasmer CLI.

The recommended way to install wasmer is via the wasmer-installer.

However, you can also install wasmer via Cargo (you will need to specify the compilers to use):

cargo install wasmer-cli --features "singlepass,cranelift"

Or by building it inside the codebase:

cargo build --release --features "singlepass,cranelift"

Features

The Wasmer supports the following features:

  • wat (default): support for executing WebAssembly text files.
  • wast(default): support for running wast test files.
  • cache (default): support or automatically caching compiled artifacts.
  • wasi (default): support for WASI.
  • emscripten (default): support for Emscripten.
  • singlepass: support for the Singlepass compiler.
  • cranelift: support for the Cranelift compiler.
  • llvm: support for the LLVM compiler.

CLI commands

Once you have Wasmer installed, you can start executing WebAssembly files easily:

Get the current Wasmer version:

wasmer -V

Execute a WebAssembly file:

wasmer run myfile.wasm

Compile a WebAssembly file:

wasmer compile myfile.wasm -o myfile.wasmu

Run a compiled WebAssembly file (fastest):

wasmer run myfile.wasmu
