Running Goblins on Hoot

Architecture Hoot: Guile in WASM
,
1

I’ve been trying to get Goblins running on Hoot today and running into some issues. Been trying to get acclimated to the way Hoot handles module discovery, and so far I’ve gotten somewhere by adding the guile-goblins repo as a submodule within my repo/adding it to the load path with guild compile-wasm -L.

But a dependency of guile-goblins, (ice-9 vlist), seems to be unavailable:

jfred@reform ~/src/wasm-test [env]$ guild compile-wasm -L modules/goblins test.scm

I found one reference to this in an old Hoot issue: Stub/shim enough stuff to get (ice-9 format) kinda working (!248) · Merge requests · spritely / Guile Hoot · GitLab

…but I’m on Hoot 0.6.0 so I should have these changes I’d imagine. And (ice-9 vlist) should be part of Guile’s standard library, right?

(As an aside: is it expected that I’d need to add Goblins to my load path manually vs. having Guile discover it in my load path? Because I do have guile-goblins installed in the same manifest.)

(ice-9 vlist) is part of Guile’s standard library but not Hoot’s. Add whatever directory holds Guile’s module sources to HOOT_LOAD_PATH or add an additional -L flag.
