:: String -> [String] package:MissingH

Splits a string around whitespace. Empty elements in the result list are automatically removed.

Similar to NameManip but the first element won't be /.

nice_slice "/" -> []
nice_slice "/foo/bar" -> ["foo", "bar"]

Split a path in components. Repeated "/" characters don't lead to empty components. "." path components are removed. If the path is absolute, the first component will start with "/". ".." components are left intact. They can't be simply removed, because the preceding component might be a symlink. In this case, realpath is probably what you need. The case that the path is empty, is probably an error. However, it is treated like ".", yielding an empty path components list. Examples:

slice_path "/"        = ["/"]
slice_path "/foo/bar" = ["/foo","bar"]
slice_path "..//./"   = [".."]
slice_path "."        = []

See unslice_path, realpath, realpath_s.

Split a file name in components. This are the base file name and the suffixes, which are separated by dots. If the name starts with a dot, it is regarded as part of the base name. The result is a list of file name components. The filename may be a path. In this case, everything up to the last path component will be returned as part of the base file name. The path gets normalised thereby. No empty suffixes are returned. If the file name contains several consecutive dots, they are regared as part of the preceding file name component. Concateneting the name components and adding dots, reproduces the original name, with a normalised path: concat . intersperse "." . slice_filename == normalise. Note that the last path component might be "..". Then it is not possible to deduce the refered directory's name from the path. An IO action for getting the real path is then necessary. Examples:

slice_filename "a.b//./.foo.tar.gz" == ["a.b/.foo","tar","gz"]
slice_filename ".x..y."             == [".x.", "y."]

See unslice_filename, slice_filename'.

This is a variant of slice_filename. It is like slice_filename, except for being more efficient, and the filename must not contain any preceding path, since this case isn't considered. See slice_filename, unslice_filename.
