Export Wasm globals ?

[ljulliar]

Hi there,

It is unclear to me whether one can access exported Wasm globals with ruby-ext-wasm. I tried and I got some kind of weird errors when instatiating a wasm module with exported globals like "global must be a const" (although the wasm code was perfectly valid)
Thanks!

I can implement that quickly, as I did for python-ext-wasm in wasmerio/wasmer-python#120. Would it fit your needs?

That would be great! In the meantime I put a workaround in place but not very elegant (basically I export a function that returns the value of the global). Side question too: is there a way from the Ruby extension to **import** a function in the wasm module that you can then call from the wasm code ? Thanks! Laurent

See #32 for the Global API.

To answzer your side question: For the moment, no, we need to support polymorphic host functions in Wasmer (the Wasmer runtime) directly. I'm working on it, since it will unblock host functions support in Ruby.

Hi Ivan, Are you thinking of releasing the wasmer rubygem 0.3.1 with this new feature for globals or there is just no need for it ? Thanks!
