This release is a pre-release and may not be stable for production use.
wasm-tools-package
wasm-tools, the Bytecode Alliance's WebAssembly toolkit, as a Python
package: the prebuilt wasm-tools executable, installable with pip. Like libusb-package, but for wasm-tools.
An unofficial redistribution (Apache-2.0 WITH LLVM-exception, Apache-2.0 or MIT).
pip install wasm-tools-package
wasm-tools parse add.wat -o add.wasm
wasm-tools validate add.wasm
Version
x.y.z.b: x.y.z is the wasm-tools release the executable is built from, b is the build number of this package
(1.262.0.0 is wasm-tools 1.262.0, first build). Requires Python 3.11+.
What is in it
| executable | wasm-tools, with all its subcommands: parse, print, validate, component, objdump, dump, strip, smith, shrink, mutate, wast, ... |
It is a console script; python -m wasm_tools_package parse ... runs it without relying on PATH.
import wasm_tools_package as wasm_tools
wasm_tools.run("parse", "in.wat", "-o", "out.wasm") # subprocess.run, check=True by default
wasm_tools.get_executable() # pathlib.Path
wasm_tools.wasm_tools_version() # "1.262.0"
Wheels
The publish workflow builds py3-none-<platform> wheels (the executable does not depend on the interpreter) for the desktop platforms
of cibuildwheel:
| Linux, manylinux | x86_64, aarch64, i686, armv7l |
| Linux, musllinux | x86_64, aarch64 |
| Windows | x64, ARM64, x86 |
| macOS | arm64, x86_64, universal2 |
See CHANGELOG.md for what each release has. There are no wheels for Android, iOS or
Pyodide: the tool runs on the machine that builds, and a package for those targets is built with the wheel of the host.
Anywhere else the sdist builds the executable from source and needs Rust 1.88 or newer (cargo, e.g. from rustup)
and network access to crates.io.
The Windows executable has the C runtime linked in, the Linux and macOS ones need only the system's own libraries (a test checks it on every platform).
Development
git clone --recurse-submodules https://github.com/natify-sh/wasm-tools-package
cd wasm-tools-package
uv sync # builds wasm-tools (a few minutes, needs cargo) and installs the package in editable mode
uv run pytest
--recurse-submodules also fetches the spec test suites of wasm-tools, which the build does not need; git submodule update --init wasm-tools is enough.
To move to a new wasm-tools release: check out its tag in wasm-tools/, commit the submodule, and tag v<release>.0
(the publish workflow checks that the tag starts with the submodule's release).
License
Apache-2.0 for the packaging; wasm-tools itself is Apache-2.0 WITH LLVM-exception, Apache-2.0 or MIT. See LICENSE and NOTICE.md.

Transparency logA note on package security
PyPI is a repository for distributing packages, not a service for auditing them. While third-party security researchers and our staff do their best to detect and remove malicious packages, PyPI cannot guarantee the quality, security or suitability of any given package.
