path.Dir
Syntax
path.Dir PATH
path.Dir returns all but the last element of PATH, typically PATH’s directory.
The returned path will never end in a slash.
If PATH is empty, . is returned.
Note: On Windows, PATH is converted to slash (/) separators.
{{ path.Dir "a/news.html" }} → "a"
{{ path.Dir "news.html" }} → "."
{{ path.Dir "a/b/c" }} → "a/b"
{{ path.Dir "/x/y/z" }} → "/x/y"
