什么是最小的 stack.yaml 文件？

Question

I have projects compiling with cabal build (but using hpack for the convenience). For some reason, I would like to compile them with stack build . What goes into a minimal stack.yaml file?

The stack documentation gives details what goes into such a file, but does not show a minimal (or any, as much as I can see) example. I fear to use stack init on an existing project for unintended consequences.

What is a small example from which to go?

Answer 1

A minimal stack.yaml :

resolver: lts-19.16 # for ghc 9.0.2 newest lts

packages:
- .

A not-so minimal skeleton from which to expand:

resolver: lts-19.16 # for ghc 9.0.2 newest lts

packages:
- .
 
extra-deps:  # include here other local packages

ghc-options:
  "$everything": -haddock # to produce documentation with haddock
