Why switch to Variant? It's not obvious to me that it'd have better ergonomics in this case. Do you have an example where you think it's better?

@garyb

So, I wanted to parse Path any any
I see there is type AnyPath a = Either (Path a Dir) (Path a File)

... well, I need type AnyAnyPath = Path Rel Dir /\ Path Abs Dir /\ Path Rel File /\ Path Abs File

so, I thought, better to use variant

PLUS, custom parsers, e.g. Path Rel Dir /\ Path Abs Dir /\ Path Rel File

[garyb]

Ah I see, yeah I guess that does make sense!

[garyb]

Not sure what the deal is with the npm issue now 🤨, I'm still mostly not using spago so I don't know if that's a known thing/there's a workaround.

The action defaults to search for the dependency file (package-lock.json, npm-shrinkwrap.json or yarn.lock) in the repository root, and uses its hash as a part of the cache key

maybe they dont say it, but they cache global node_modules too

and I need to remove to reinstall

If you are going to make pathy depend on https://github.com/natefaubion/purescript-variant , @srghma , then you should consider talking to Nate Faubion about moving variant to purescript-contrib. The packages in purescript-contrib should depend only on core libs and other purescript-contrib packages, and not on stuff in people’s personal accounts ( as @garyb once explained to me.)
