WebAssembly - WASI Support

[woncheol-kim]

What problem are you are trying to solve?

How do you think rclone should be changed to solve that?

Hello, first off, I want to express my gratitude for this incredible software that I rely on daily.

After conducting a search on this site, I've observed that there was an issue related to the WebAssembly build of rclone. I'm interested in obtaining a copy. Would it be possible to acquire one?

My intention is to utilize rclone within a-Shell, an iOS terminal with certain limitations. The developer suggests that compiling from source code into a WebAssembly build using WASI-SDK might enable its functionality within a-Shell, potentially bypassing Apple Store policies since it's technically not binary code subject to those policies.

I attempted to compile it myself, first in a Linux terminal and then in a macOS terminal, but when I executed it in a-Shell, I only received an empty shell without any feedback. I'm not a developer myself, and my attempts were made with the assistance of Copilot AI. Explaining step by step what might have gone wrong with my attempts would likely be a lengthy process.

For reference, here's the link to a-Shell's GitHub repository: https://github.com/holzschu/a-shell

Thank you.

The core of rclone builds with wasm, however we've never done wasi which would enable the command line usage you are looking for.

So that is why it doesn't work.

It would be a nice project to make things work with wasi for someone since go now has support for it directly

I'm not sure how hard this would be though!
