Types

type Path 

type Path struct {

func ExecutablePath 

func ExecutablePath() Path

ExecutablePath returns the path to the running executable.

func FindExecutable 

func FindExecutable(name string) (Path, error)

func (Path) Files 

func (p Path) Files() PathList

Files reads the list of files in path.

func (Path) Glob 

func (p Path) Glob(pattern ...string) PathList

func (Path) Info 

func (p Path) Info() os.FileInfo

Info returns the file information for ths path.

func (Path) IsDir 

func (p Path) IsDir() bool

IsDir returns true if the path exists and is a directory.

func (Path) IsEmpty 

func (p Path) IsEmpty() bool

IsEmpty returns true if the path has no value.

func (Path) Join 

func (p Path) Join(join ...string) Path

Join returns a path formed from joining this base with a child path. If there are any / characters in the strings, they will be converted to they system separator.

func (Path) MarshalJSON 

func (p Path) MarshalJSON() ([]byte, error)

MarshalJSON implements custom JSON marshalling to write paths as simple JSON strings.

func (Path) Matches 

func (p Path) Matches(patterns ...string) bool

Matches returns true if the Path matches any of the patterns.

func (Path) NoExt 

func (p Path) NoExt() Path

NoExt returns the path excluding the file extension or '.'.

func (Path) Parent 

func (p Path) Parent() Path

Parent returns the parent directory of the path, if it has one. It will return the canonical version of the path if it is a root.

func (Path) RelativeTo 

func (p Path) RelativeTo(base Path) (string, error)

RelativeTo returns the path of this File relative to base.

func (*Path) Set 

func (p *Path) Set(value string) error

Set assigns the value of the path. This conforms to the flag variable interface.

func (Path) Slash 

func (p Path) Slash() string

Slash returns the full absolute path using the / separator.

func (Path) Smash 

func (p Path) Smash() (Path, string, string)

Smash returns the parent, name and extension of a path.

func (Path) Split 

func (p Path) Split() (Path, string)

Split returns the parent and name of the path.

func (Path) SplitExt 

func (p Path) SplitExt() (Path, string)

SplitExt returns the path excluding the file extension and the file extension. The extension includes the '.'.

func (Path) String 

func (p Path) String() string

The default string form uses the system representation.

func (Path) System 

func (p Path) System() string

System returns the full absolute path using the system separator.

func (Path) Timestamp 

func (p Path) Timestamp() time.Time

Timestamp returns the last modified time reported by the file system.

func (Path) URL added in v0.5.0 

func (p Path) URL() *url.URL

URL returns the full absolute path using the / separator prefixed by the URL file scheme.

func (*Path) UnmarshalJSON 

func (p *Path) UnmarshalJSON(data []byte) error

UnmarshalJSON implements custom JSON unmarshalling to read strings a paths.

func (PathList) String 

func (l PathList) String() string

func (PathList) Swap

	// contains filtered or unexported fields
}

PathSet is a list of file paths that does not allow duplicates.

func (PathSet) Append 

func (s PathSet) Append(paths ...Path) PathSet
