Comments in inherits have extra newlines inserted.

[bakhtiyarneyman]

paths = builtins.attrValues {
  inherit
    (pkgs)
    foo
    # This comment was supposed to be attached to bar.
    
    # But it gets split like this.
    
    bar
    baz
}

Besides the extra newlines, those lines are full of white spaces.

This happens with any trailing comment inside an expression:

{
  a = assert true; #
__
    1;
  b =
    foo #
____
    bar;
}

(superfluous spaces replaced with underscores for clarification)

I just experienced this issue.

Perhaps this was fixed in 3.1.0?

Before:

{paths = builtins.attrValues {
  inherit
    (pkgs)
    foo
    # This comment was supposed to be attached to bar.
    # But it gets split like this.
    bar
    baz;
};}

After

{
  paths = builtins.attrValues {
    inherit
      (pkgs)
      foo
      # This comment was supposed to be attached to bar.
      # But it gets split like this.
      bar
      baz
      ;
  };
}
