path.Split

Replaces path separators with slashes (`/`) and splits the resulting path immediately following the final slash, separating it into a directory and file name component.

If there is no slash in the given path, path.Split returns an empty directory, and file set to path. The returned values have the property that path = dir+file.

{{ $dirFile := path.Split "a/news.html" }}
{{ $dirFile.Dir }} → a/
{{ $dirFile.File }} → news.html

{{ $dirFile := path.Split "news.html" }}
{{ $dirFile.Dir }} → "" (empty string)
{{ $dirFile.File }} → news.html

{{ $dirFile := path.Split "a/b/c" }}
{{ $dirFile.Dir }} → a/b/
{{ $dirFile.File }} → c
