pybinaryen 1.3

python bindings for the binaryen webassembly library

Python interface to the Binaryen library

This module provides a Python interface to the binaryen webassembly library.

That library has to be installed separately, make sure it is available on your system as a shared library. You may need to add something to your link library search path to let python pick it up.

Requires Python 3.5 or newer. Also works on pypy3 (because it uses cffi).

Example

Running the following code:

import binaryen

module = binaryen.ModuleCreate()
params = binaryen.TypeCreate([binaryen.TypeInt32(), binaryen.TypeInt32()], 2)
results = binaryen.TypeInt32()
x = binaryen.LocalGet(module, 0, binaryen.TypeInt32())
y = binaryen.LocalGet(module, 1, binaryen.TypeInt32())
add = binaryen.Binary(module, binaryen.AddInt32(), x, y)
adder = binaryen.AddFunction(module, b"adder", params, results, binaryen.ffi.NULL, 0, add)
binaryen.ModulePrint(module)
binaryen.ModuleDispose(module)

results in the following Webasm Text output:

(module
 (type $i32_i32_=>_i32 (func (param i32 i32) (result i32)))
 (func $adder (; 0 ;) (param $0 i32) (param $1 i32) (result i32)
  (i32.add
   (local.get $0)
   (local.get $1)
  )
 )
)
