		Package path implements utility routines for manipulating slash-separated
		paths.
		
		The path package should only be used for paths separated by forward
		slashes, such as the paths in URLs. This package does not deal with
		Windows paths with drive letters or backslashes; to manipulate
		operating system paths, use the [path/filepath] package.


Code Examples

	
		package main
		
		import (
			"fmt"
			"path"
		)
		
		func main() {
			fmt.Println(path.Base("/a/b"))
			fmt.Println(path.Base("/"))
			fmt.Println(path.Base(""))
		}

	
		package main
		
		import (

				"a//c",
				"a/c/.",
				"a/c/b/..",
				"/../a/c",
				"/../a/b/../././/c",
				"",
			}
		
			for _, p := range paths {
				fmt.Printf("Clean(%q) = %q\n", p, path.Clean(p))
			}
		
		}

Package-Level Functions (total 8)


	
		Base returns the last element of path.
		Trailing slashes are removed before extracting the last element.
		If the path is empty, Base returns ".".
		If the path consists entirely of slashes, Base returns "/".


	
		Clean returns the shortest path name equivalent to path
		by purely lexical processing. It applies the following rules
		iteratively until no further processing can be done:
		
		 1. Replace multiple slashes with a single slash.
		 2. Eliminate each . path name element (the current directory).
		 3. Eliminate each inner .. path name element (the parent directory)
		    along with the non-.. element that precedes it.
		 4. Eliminate .. elements that begin a rooted path:
		    that is, replace "/.." by "/" at the beginning of a path.
		
		The returned path ends in a slash only if it is the root "/".
		
		If the result of this process is an empty string, Clean
		returns the string ".".

		Getting Dot-Dot Right,”
		https://9p.io/sys/doc/lexnames.html


	
		Dir returns all but the last element of path, typically the path's directory.
		After dropping the final element using [Split], the path is Cleaned and trailing
		slashes are removed.
		If the path is empty, Dir returns ".".
		If the path consists entirely of slashes followed by non-slash bytes, Dir
		returns a single slash. In any other case, the returned path does not end in a
		slash.


	
		Ext returns the file name extension used by path.
		The extension is the suffix beginning at the final dot
		in the final slash-separated element of path;
		it is empty if there is no dot.


	
		IsAbs reports whether the path is absolute.


	
		Join joins any number of path elements into a single path,
		separating them with slashes. Empty elements are ignored.
		The result is Cleaned. However, if the argument list is
		empty or all its elements are empty, Join returns
		an empty string.


	
		Match reports whether name matches the shell pattern.
		The pattern syntax is:
		
			pattern:
				{ term }
			term:
				'*'         matches any sequence of non-/ characters
				'?'         matches any single non-/ character
				'[' [ '^' ] { character-range } ']'
				            character class (must be non-empty)
				c           matches character c (c != '*', '?', '\\', '[')
				'\\' c      matches character c
		
			character-range:
				c           matches character c (c != '\\', '-', ']')
				'\\' c      matches character c
				lo '-' hi   matches character c for lo <= c <= hi
		
		Match requires pattern to match all of name, not just a substring.
		The only possible returned error is [ErrBadPattern], when pattern
		is malformed.


	
		Split splits path immediately following the final slash,
		separating it into a directory and file name component.
		If there is no slash in path, Split returns an empty dir and
		file set to path.
		The returned values have the property that path = dir+file.
