Can't find bundled superbol-free executable on darwin-arm64

[ilyagr]

A bit of an experience report: I successfully compiled the VS Code extension on ARM Mac OS using Nix. However, the extension did not work when installed because it couldn't find the LSP executable.

The reason seems to be that the LSP executable was named superbol-free-linux-x64, but the extension couldn't find it under that name even though it was in the correct _dist directory.

Workaround: The file should renamed from $HOME/.vscode/extensions/ocamlpro.superbol-0.1.5/_dist/superbol-free-linux-x64 to $HOME/.vscode/extensions/ocamlpro.superbol-0.1.5/_dist/superbol-free. After that, things work fine.

Relatedly, the VSIX file generated by the build process also ends up being called superbol-vscode-platform-0.1.5-linux-x64.vsix for some reason.

I found the workaround after looking at

superbol-studio-oss/src/vscode/superbol-vscode-platform/superbol_languageclient.ml

Lines 43 to 54 in 922588f

	let find_superbol root =
	let open Node.Process in
	let prefix = "superbol-free" in
	let suffix = if platform == "win32" then ".exe" else "" in
	Vscode.Uri.fsPath @@ find_existing @@ List.map (fun name ->
	Vscode.Uri.joinPath root ~pathSegments:[name]) @@ [
	Format.asprintf "%s-%s-%s%s" prefix platform arch suffix;
	Format.asprintf "%s-%s%s" prefix platform suffix;
	Format.asprintf "%s%s" prefix suffix
	] @ if platform = "darwin" && arch = "arm64" then
	[ Format.sprintf "%s-%s-%s%s" prefix platform "x64" suffix]
	else

Hope this helps, and thanks for making this extension!

Aside: To emphasize, the LSP executable that was built was in fact a darwin-arm64 executable despite the name:

$ file superbol-free-linux-x64
superbol-free-linux-x64: Mach-O 64-bit executable arm64
