func NewDupName ¶

func NewDupName[T any](
	newNamer func(string) Namer,
	entries []T,
	freeze bool,
	pickName func(T) string,
) *DupName

The entries parameter exists to ensure that the non-duplicative values contained in entries are not changed.

Example:

// If a directory contains "foo.txt" ...
path := "path/to/the/directory"
entries, _ := os.ReadDir(path)
pick: = func(x os.DirEntry) string { return x.Name() }

// freeze parameter is set to 'false', nameA is "foo.txt" and nameB is "foo(2).txt".
dupName := NewDupName(NewNumberedName, entries, false, pick)
nameA, _ := dupName.Rename("foo.txt")
nameB, _ := dupName.Rename("foo.txt")

// freeze parameter is set to 'true', nameC is "foo(2).txt" and nameD is "foo(3).txt".
dupName = NewDupName(NewNumberedName, entries, true, pick)
nameC, _ := dupName.Rename("foo.txt")
nameD, _ := dupName.Rename("foo.txt")

// In the above case, it would be more suitable to set freeze parameter to 'true'.
