Support for Python3 as the python interpreter?

[Leedehai]

WebAssembly's Getting Started says it needs Python2.7
Now it's 2018 and tools are adding support for Python3, and I think WebAssembly needs to be compatible with Python3, too. The later, the more difficult to add.

I believe Python 3 is supported in all the tools referenced there, so it may be that just those docs need to be updated. If so, can file an issue or PR here: https://github.com/WebAssembly/website ; otherwise, if you find a tool not fully working with Python 3, please file an issue in that tool's repo.

The build will fail if the python interpreter is not installed or on the PATH and build-js.sh is used to build binaryen.js and wasm.js from source. So every occurrence of python should be changed to python3 to make binaryen compatible with Python 3 at least. I haven't tested yet if the rest of the code is compatible with Python 3. Please remember that Python will reach EOL status next year. https://pythonclock.org/

I can do this.

Hi,

thanks for working on python3 support. However the work isn't complete yet. Binaryen 88 will fail to build from source because you forgot to replace the python command in build-js.sh with python3. There are also still various occurrences of #!/usr/bin/env python which should be #!/usr/bin/env python3

Thanks @apoleon, reopening. Hopefully someone has time to do those things, PRs welcome.
