This release is a pre-release and may not be stable for production use.
wabt-package
WABT, the WebAssembly Binary Toolkit, as a Python package: the prebuilt
command-line tools and the wasm2c runtime, installable with pip. Like libusb-package, but for WABT.
An unofficial redistribution (Apache-2.0).
pip install wabt-package
wat2wasm add.wat -o add.wasm
wasm2c add.wasm -o add.c
Version
x.y.z.b: x.y.z is the WABT release the tools are built from, b is the build number of this package
(1.0.42.0 is WABT 1.0.42, first build).
What is in it
| tools | spectest-interp, wasm-interp, wasm-objdump, wasm-stats, wasm-strip, wasm-validate, wasm2c, wasm2wat, wast2json, wat-desugar, wat2wasm |
| runtime | the C sources the code of wasm2c is compiled with (wasm-rt.h, wasm-rt-impl.c, ...), of the same version |
Each tool is a console script; python -m wabt_package wat2wasm ... runs one without relying on PATH.
import wabt_package as wabt
wabt.run("wat2wasm", "in.wat", "-o", "out.wasm") # subprocess.run, check=True by default
wabt.get_executable("wasm2c") # pathlib.Path
wabt.runtime_dir() # directory of wasm-rt.h, wasm-rt-impl.c, ...
wabt.wabt_version() # "1.0.42"
SIMD
The C that wasm2c writes for a module with SIMD instructions includes <simde/wasm/simd128.h>. The package does not
ship simde (neither do WABT's own releases, as far as the install rules of
1.0.42 go): add its headers with -I when compiling such a module. Modules without SIMD need nothing but runtime_dir().
Wheels
py3-none-<platform> wheels (the executables do not depend on the interpreter): Linux manylinux and musllinux
(x86_64, aarch64), Windows (x64, ARM64), macOS (arm64, x86_64). Anywhere else the sdist builds the tools from source and
needs a C++ compiler (cmake and ninja are fetched from PyPI).
The executables are linked statically against the C++ runtime and use WABT's own SHA-256 (no OpenSSL).
Development
git clone --recurse-submodules https://github.com/ballistics-lab/wabt-package
cd wabt-package
git -C wabt submodule update --init --depth 1 third_party/picosha2 # the only nested submodule needed
uv sync # builds WABT (a minute) and installs the package in editable mode
uv run pytest
To move to a new WABT release: check out its tag in wabt/, 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, as WABT. See LICENSE and NOTICE.md.
