Build wasm4 games using Roc

roc-wasm4's Issues

Unused defs cause build to fail

This program runs successfully, but if I comment out either the unused import or the unused def, the build fails.

app "drum"
    packages {
        w4: "platform/main.roc",
    }
    imports [
        w4.Task.{ Task },
        # w4.W4,
    ]
    provides [main, Model] to w4

Program : {
    init : Task Model [],
    update : Model -> Task Model [],
}

Model : {}

main : Program
main = { init, update }

init : Task Model []
init =
    Task.ok {}

update : Model -> Task Model []
update = \model ->
    Task.ok model

# unused = "foo"

$ zig build -Dapp=foo.roc run

── UNUSED DEFINITION ───────────────────────────────────────────────── foo.roc ─

unused is not used anywhere in your code.

29│  unused = "foo"
     ^^^^^^

If you didn't intend on using unused then remove it so future readers
of your code don't wonder why it is there.

I am using the most recent version of the platform, roc from Jan 12, and apple silicon.
