Create WebAssembly Guide with various languages

[nickvidal]

Is there an existing issue for this?

• I have searched the existing issues

Description

We want to create a WebAssembly Guide with a simple example using various programming languages that currently have support for WASI:

https://enarx.dev/docs/WebAssembly/Introduction

Fermyon has a good matrix showing languages that support WASI:

https://www.fermyon.com/wasm-languages/webassembly-language-support

Among these languages, recently we saw JavaScrip/TypeScript getting support:

https://blog.suborbital.dev/bringing-javascript-and-typescript-to-suborbital

Acceptance Criteria

The languages we are interested in are the following, currently ordered by their support of WASI and importance:

• Rust
• C
• C++
• Go
• JavaScript
• TypeScript
• AssemblyScript
• .NET
• Ruby
• Grain
• Zig
• Python
• Swift
• Kotlin
• Java
• Erlang
• Haskell
• Lisp
• COBOL

Suggestions for a technical implementation

We are thinking in using Fibonacci as an example:

If you are interested in contributing, please:

• Implement Fibonacci in your language of choice
• Add a markdown file to docs/WebAssembly
• Add a sidebar link at sidebars.js
• Create a PR against this repo

Thank you!

I have the C++ Demo already created
Here is the Link to the Repository for the Demo in C++:
https://github.com/Deepansharora27/HammingCodeGeneration

[Deepansharora27]

Shall I Raise another issue for the C++ Example or will embedding it here will work Nick ?

@nickvidal Hi Nick,
This is my demo example for Fibonacci Example in C++ as well.

So, C++ is done from my side now.

[moksh-pathak]

I will be implementing demo example for Fibonacci in Golang.

I will be implementing demo example for Fibonacci in Golang.

Hi Moksh, please check with Jennifer before, as I believe she's also interested in Golang. Maybe she can leave the Golang implementation to you, and do some exploration around Python.

[jnyfah]

@moksh-pathak I have done that of Golang and rust, currently trying C# and python

[moksh-pathak]

No worries @jnyfah. Good going!

[nickvidal]

If you are adventurous, you might want to explore AssemblyScript or Grain! :)

[moksh-pathak]

Would like to give it a shot!

[moksh-pathak]

I am also working on the Swift demo.

[mayankkumar2]

@nickvidal is kotlin,Erlang,Haskell,C up for taking?

[nickvidal]

Hi @mayankkumar2, I believe @Deepansharora27 is working on the C example, but the other ones are open.

[Deepansharora27]

Yes right @nickvidal I have also made a Pull Request for the Same.
Also I have already done work on the Java and Kotlin side of things.
Telling so that it doesn't block the workflow for others 😊

[mayankkumar2]

Ok then, I will take up Haskell and Erlang.

[aryankaushikdev]

I would like to create the guide with javascript.

[mayankkumar2]

I tried out erlang and Haskell, the tooling is giving me some trouble. lumen's latest release seems to not even compile the hello world example, will have to build from source and document the same. For Haskell with asterius, I got stuck with a weird error ahc-dist: internal error: Unable to commit 2902458368 bytes of memory, have been trying to debug what's going wrong :(. The example code for both these languages seems to compile perfectly with their native compilers but not with the web assembly toolings.

[nickvidal]

Hi @mayankkumar2, no worries. Perhaps the tooling is "not there" yet.

Would you be interested in exploring Python (with @jnyfah ) or Java (with @Deepansharora27)?

[nickvidal]

Regarding Python, I got some recommendations from @tiran:

I just got WASI builds working with help of https://github.com/singlestore-labs/wasix .

$ wasmtime --mapdir=.::../.. -- ./python.wasm -c "import sys;
print(f'Hello {sys.platform} from {[sys.implementation.name](http://sys.implementation.name/)}')"
Hello wasi from cpython

You can find instructions and build container at
https://github.com/tiran/cpython_builddep/#webassembly-build .

You have to run the command from a recent cpython git checkout. Next build a
native Python with ./build-python-build.sh and finally wasm32-wasi with
./build-python-wasi.sh

[mayankkumar2]

Sure @nickvidal, I will connect with them on Rocket Chat then, regarding what all they have done (tried out) till now.

[Deepansharora27]

@mayankkumar2 You can connect with Jennifer for python for now as Java is something that I would like to work on independently till Sunday and maybe if issue still prevails , then we can connect together on Monday

Anyone with .NET knowledge who wants to try this?

I would like to take this up

[nickvidal]

Anyone interested in exploring Ruby?

I saw that some hours ago over Twitter, I have started checking it out

[IIITM-Jay]

Hi @nickvidal , an outreachy applicant here,
May I work on swift or any other language?

[moksh-pathak]

Hi @IIITM-Jay, I have already taken up the Swift WASM demo before.
