Missing module Unsafe.Coerce? #52

Closed PilchardFriendly closed 4 years ago

PilchardFriendly commented 4 years ago

I've only been using go for 30 minutes, and purescript for 3 days, so I'm not quite sure what to do next.... please go easy on me...

I've got spago to run the build (removed my GOPATH, and it all worked well). I've got a Main in the project root.

spago version
0.14.0
psgo --version
master, commit b5b1635138ba5e3f5dc90df77e3a2fb043e1a7e1

When I run ./Main it dumps at my option parser -> Data.Exists -> Unsafe.Coerce

What else can I tell you?

Stacktrace:


panic: Foreign value 'unsafeCoerce' for purescript module 'Unsafe.Coerce' not found

Ok - my /purescript-native/ffi_loader.go was missing _ "github.com/purescript-native/go-ffi/purescript-unsafe-coerce"

I've added that, and the problem changed:

The offending line is below. So - I'll go and have a look at ffi js code, and port it, right?


 var options Any = Apply(Options_Applicative_Extra.PS__execParser(), Apply(Options_Applicative_Builder.PS__info(), Apply(Options_Applicative_Internal_Utils.PS__apApplyFlipped(), Options_Applicative_Types.PS__parserApply(), PS__programOptions(), Options_Applicative_Extra.PS__helper()), Apply(Data_Semigroup.PS__append(), Options_Applicative_Builder.PS__infoModSemigroup(), Options_Applicative_Builder.PS__fullDesc(), Apply(Data_Semigroup.PS__append(), Options_Applicative_Builder.PS__infoModSemigroup(), Apply(Options_Applicative_Builder.PS__progDesc(), "Shokinin 20"), Apply(Options_Applicative_Builder.PS__header(), "Get to the food truck!")))))
    return func() Any {
        var seed Any = Run(Random_LCG.PS__randomSeed())
        var opts Any = Run(options)
        var logs Any = Run(Apply(Teletype.PS__runTeletype(), Apply(PS__program(), Apply(strategy, opts), seed)))
        return logs
    }```

I've added that, and the problem changed:

Sorry, I don't see error message (for the panic); I'm guessing some of the output is missing?

Otherwise, I'm guessing you're correct in identifying some missing implementations.
