func
Abs(path
string) (
string,
error)
Abs returns an absolute representation of path.
If the path is not absolute it will be joined with the current
working directory to turn it into an absolute path. The absolute
path name for a given file is not guaranteed to be unique.
Abs calls Clean on the result.
func
Base(path
string)
string
Base returns the last element of path.
Trailing path separators are removed before extracting the last element.
If the path is empty, Base returns ".".
If the path consists entirely of separators, Base returns a single separator.
func
Clean(path
string)
string
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 Separator elements with a single one.
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,
assuming Separator is '/'.
The returned path ends in a slash only if it represents a root directory,
such as "/" on Unix or `C:\` on Windows.
Finally, any occurrences of slash are replaced by Separator.
If the result of this process is an empty string, Clean
returns the string ".".

Getting Dot-Dot Right,''

func
Dir(path
string)
string
Dir returns all but the last element of path, typically the path's directory.
After dropping the final element, Dir calls Clean on the path and trailing
slashes are removed.
If the path is empty, Dir returns ".".
If the path consists entirely of separators, Dir returns a single separator.
The returned path does not end in a separator unless it is the root directory.
func
EvalSymlinks(path
string) (
string,
error)
EvalSymlinks returns the path name after the evaluation of any symbolic
links.
If path is relative the result will be relative to the current directory,
unless one of the components is an absolute symbolic link.
EvalSymlinks calls Clean on the result.
func
Ext(path
string)
string
Ext returns the file name extension used by path.
The extension is the suffix beginning at the final dot
in the final element of path; it is empty if there is
no dot.
func
FromSlash(path
string)
string
FromSlash returns the result of replacing each slash ('/') character
in path with a separator character. Multiple slashes are replaced
by multiple separators.
func
Glob(pattern
string) (matches []
string, err
error)
Glob returns the names of all files matching pattern or nil
if there is no matching file. The syntax of patterns is the same
as in Match. The pattern may describe hierarchical names such as
/usr/*/bin/ed (assuming the Separator is '/').
Glob ignores file system errors such as I/O errors reading directories.
The only possible returned error is ErrBadPattern, when pattern
is malformed.
func
HasPrefix(p, prefix
string)
bool
HasPrefix exists for historical compatibility and should not be used.
Deprecated: HasPrefix does not respect path boundaries and
does not ignore case when required.
func
Join(elem ...
string)
string
Join joins any number of path elements into a single path,
separating them with an OS specific Separator. 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.
On Windows, the result will only be a UNC path if the first
non-empty element is a UNC path.
func
Match(pattern, name
string) (matched
bool, err
error)
Match reports whether name matches the shell file name pattern.
The pattern syntax is:
pattern:
{ term }
term:
'*' matches any sequence of non-Separator characters
'?' matches any single non-Separator 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.
On Windows, escaping is disabled. Instead, '\\' is treated as
path separator.
func
Rel(basepath, targpath
string) (
string,
error)
Rel returns a relative path that is lexically equivalent to targpath when
joined to basepath with an intervening separator. That is,
Join(basepath, Rel(basepath, targpath)) is equivalent to targpath itself.
On success, the returned path will always be relative to basepath,
even if basepath and targpath share no elements.
An error is returned if targpath can't be made relative to basepath or if
knowing the current working directory would be necessary to compute it.
Rel calls Clean on the result.
var
SkipDir error
SkipDir is used as a return value from WalkFuncs to indicate that
the directory named in the call is to be skipped. It is not returned
as an error by any function.
func
Split(path
string) (dir, file
string)
Split splits path immediately following the final Separator,
separating it into a directory and file name component.
If there is no Separator in path, Split returns an empty dir
and file set to path.
The returned values have the property that path = dir+file.
func
SplitList(path
string) []
string
SplitList splits a list of paths joined by the OS-specific ListSeparator,
usually found in PATH or GOPATH environment variables.
Unlike strings.Split, SplitList returns an empty slice when passed an empty
string.
func
ToSlash(path
string)
string
ToSlash returns the result of replacing each separator character
in path with a slash ('/') character. Multiple separators are
replaced by multiple slashes.
func
VolumeName(path
string)
string
VolumeName returns leading volume name.
Given "C:\foo\bar" it returns "C:" on Windows.
Given "\\host\share\foo" it returns "\\host\share".
On other platforms it returns "".
func
Walk(root
string, walkFn
WalkFunc)
error
Walk walks the file tree rooted at root, calling walkFn for each file or
directory in the tree, including root. All errors that arise visiting files
and directories are filtered by walkFn. The files are walked in lexical
order, which makes the output deterministic but means that for very
large directories Walk can be inefficient.
Walk does not follow symbolic links.
