Build fails with rescript 11.1.4

[rizo]

Getting the following build error when compiling rescript sources:

rescript: [6/6] src/rescript/Spice.cmj
FAILED: src/rescript/Spice.cmj

  We've found a bug for you!
  /home/rizo/Work/FCL/Code/fcl-app/node_modules/@greenlabs/ppx-spice/src/rescript/Spice.res:27:50-62

  25 │   }

  27 │ let intToJson = (i): Js.Json.t => Js.Json.Number(Float.fromInt(i))
  28 │ let intFromJson = j =>
  29 │   switch (j: Js.Json.t) {

  The module or file Float can't be found.

This seems to be related to the implicit usage of the Float module, which is not in scope. I suspect this has to do with the fact that the latest rescript version doesn't automatically expose some builtin modules.

Thank you for reporting the issue.
Can you inform me of what version of ppx_spice you are using?

This error was produced with v0.2.3. I've downgraded to v0.2.2, which works fine.

I tried altering Spice.res to add some opens: open Belt worked for the Float case, but BigInt wasn't in scope.

Correct.

I've added this section for the compiler compatibility guide before. I'll revise this more accurately. https://github.com/green-labs/ppx_spice#compatibility-on-the-compiler-versions

I'm having the same issue with v11, downgrading to v0.2.2 solves it.

Is there any progress on this issue?

There is no functional difference between v0.2.3 and v0.2.2, it's just that v0.2.3 is the version that starts supporting the v12 compiler. So you can use v0.2.2 for v11.

v11 -> v0.2.2
v12 -> v0.2.3
