Indeed, I use the following function in my projects:
# Copy everything under src into the Nix store except
# those paths that don't have one of the specified
# allowedPrefixes.
whitelistSource = src: allowedPrefixes:
builtins.filterSource
(path: type:
lib.any (allowedPrefix: lib.hasPrefix
(toString (src + "/${allowedPrefix}"))
path
) allowedPrefixes
) src;
In my Haskell projects I use it like:
src = whitelistSource ./. [
"my-project.cabal"
"src"
];
All other non-essential files like "dist", ".ghci", etc. are automatically
filtered out.
