For those interested: @TerrorJack successfully compiled pandoc to WASM via ghc-wasm-meta.

Fantastic work!

It's too bad Lua filters don't work yet. This makes it less useful.

I experimented with it briefly using the iOS app a-Shell. I copied the URL of pandoc.wasm from the README and downloaded it with curl. When I run it, it hangs, but if I press CTRL-C, it produces the expected output. The hang isn't due to an attempt to read from stdin, because CTRL-D has no effect. Probably, it needs to be build with a-Shell's custom WASI-SDK, and perhaps some of TerrorJack's customization needs to be undone. Since this is not wasmtime but another platform, it may be that Lua filters can be made to work. However, I don't expect to dedicate time to this in the near future. Since I have no experience with Haskell, I imagine I'd have a hard time making a custom build of pandoc.
