Motivation for this change
Worktree locations were causing hash changes. With the
name
parameter you can avoid that.To quote the new inline doc: We recommend setting
name
wheneversrc
is syntactically./.
. Otherwise, you depend on./.
's name in the parent directory, which can cause inconsistent names, defeating caching.From the commit message
This change is API-compatible and hash-compatible with the previous
version.
At first I considered to write a rename function too, but adding
it name to cleanSourceWith was a no-brainer for ease of use. It
turns out that a rename function isn't any more useful than
cleanSourceWith.
To avoid having to write the identity predicate when renaming,
the filter is now optional.
builtins.path is supported since Nix 2.0 which is required by nixpkgs
