Thanks for sharing.

Issue running the examples on linux (or maybe it is due to the latest esy version?)
Hi,
I'm totally inexperienced with native reason and esy, so I don't really understand what the issue is. But I was unable to get the bucklescript (test_bs) example working.
Here is the output when I try run yarn build inside the test_bs folder:
yarn run v1.22.0
$ bsb -make-world

$ node ./copyPlatformBinaryInPlace.js
ppx_42 does not support this platform :(
ppx_42 comes prepacked as built binaries to avoid large
dependencies at build-time.
If you want ppx_42 to support this platform natively,
please open an issue at our repository, linked above. Please
specify that you are on the linux platform,
on the x64 architecture.

}
This is because esy doesn't seem to create a file called bin/ppx_42-linux-x64.exe (or the copyPlatformBinaryInPlace.js file is wrong). I don't know if this could be because something changed in the latest version of esy or what.
I got the ppx working by changing the ppx-flags in the bs-config.json to be as follows:
"ppx-flags": [
// "esy x ppx_42"
"../_esy/default/build/default/bin/Bin.exe"
],
Anyway, big thanks for putting this together, building ppxs isn't a very approachable task for beginners at the moment, and this definitely helps a lot!
Include esy fallback for unsupported platforms
@aantron added in bisect_ppx a really nice fallback approach where after downloading, the ppx will build with esy if the user platform is not supported by the prebuilt binaries.
Would be nice to add this to the hello-ppx-esy example.
Error running esy build
Hello! I'm trying to run the command esy build as specified in the README, and I'm getting the following error:

Please add a <package>.opam file at the project root so that these elements

Any ideas on how to fix it? Note that I'm quite new to Reason so I apologize for an inconvenience. I'm attempting to learn how to write a PPX 😄 .
Thanks in advance!
