Fields of Lake package defined in current working directory?

Stream: general

[Mekeor Melire]

Given a Lean4 Lake package source code in /my/great/program and a shell with current-working-directory being somewhere beneath that path, is it possible to easily and correctly access the fields (path to package root, path to lakefile in use, package name etc.) of the Lake package via Lean and Lake themselves? I'm imagining something along these lines:

lake env lean --stdin --run <<EOF
import Lake
def main : IO Unit := IO.println Lake.Some.Magic.currentPackage.dir
EOF
