Tracking pending PR required for testing

[hhugo]

Use this issue to track pending PRs up-streaming changes required for testing wasm.

• Adapt to latest version of sedlex janestreet/ppx_css#3
• Mising JavaScript and Wasm stubs janestreet/basement#3
• OCaml 5.3 compatibility (try 2) janestreet/typerep#7
• Wasm_of_ocaml runtime file inhabitedtype/bigstringaf#57
• Dune: provide wasm file janestreet/core_kernel#108

Also, the following repos use the effect identifier which conflict with the effect keyword in OCaml 5.3

• bonsai
• bonsai_web
• virtual_dom

@vouillon do you have other things to add here ?

[hhugo]

Janestreet packages still miss a release compatible with wasmoo.
We need to pin base, time_now, ppx_expect and ppx_inline_test to a fork to be able to run the jsoo testsuite with wasm.
I'm thinking about vendoring https://opam.ocaml.org/packages/ppx_expect_nobase/ to fix dependency.

[hhugo]

Testing wasmoo with OCaml 5.4 is currently blocked because of janestreet packages incompatibility.

[hhugo]

The main issue is that the dev branches are no compatible with ppxlib >= 0.36.
I would be much easier if testing was based on the latest public release of janestreet packages (v0.17.*).

It would be much easier if testing was based on the latest public release of janestreet packages (v0.17.*).

It is a significant amount of work to patch these packages to add the Wasm files and enable the tests, though.
