Garbled output of Top-sorted list of all dependencies (macOS)

[andreasabel]

I would like to use cabal-plan to generate a extra-deps in a stack.yaml file automatically, using the list of all dependencies under Top-sorted:

$ cabal-plan

Unfortunately, the list of all packages gives garbled names (on macOS) for all non-core packages, due to

• The Grinch stole all the vowels: Odd naming in .cabal/store (macOS)  haskell/cabal#7209

A better access to the package names and version is provided by

$ cabal-plan fingerprint

Thus, this issue is maybe more a wart than a real problem and can wait for an upstream fix.

Use cabal-plan topo

Is this issue actionable then? UnitIds are unit-ids, they are arbitrary strings.

[andreasabel]

Use cabal-plan topo

Thanks!

I guess not.
