What's Changed

• Public API and Imports/Host Function DSL by @CharlieTap in #25

Breaking Changes

This version begins the stabilisation of a public api for chasm and hide its internals from downstream consumers. For this reason a layer of indirection has been introduced and all necessary public types are duplicated in chasm's public module.

A short summary of changes and basic migration guide are as follows:

• Creation of a store is now only possible using the factory method (previously you could call construct on the runtimes own store):

// The type will now be io.github.charlietap.chasm.embedding.shapes.Store
val store = store()

• Classes referenced in the chasms ast and runtime modules should now use the corresponding classes of the same name in the package io.github.charlietap.chasm.embedding.shapes.*

For example

// function
io.github.charlietap.chasm.embedding.shapes.Function

⚠️ There is one exception and that is the ModuleInstance is now known as io.github.charlietap.chasm.embedding.shapes.Instance

Other changes

There is also an experimental DSL builder api for defining imports and host functions, for now this will be undocumented as it may change as we develop a WASI layer on top of it. But as a sneak peak...

fun WasiPreview1(store: Store, memory: Memory) = imports(store) {
    function {
        moduleName = "wasi_preview_"
        entityName = "fd_write"
        type = functionType {
            params { i32() }
            results { i32() }
        }
        reference(fdWrite(memory))
    }
}
