Variables

var ErrNotFound = errors.New("executable file not found in $PATH")

ErrNotFound is the error resulting if a path search failed to find an executable file.

Functions

func FindGit

func FindGit() (string, error)

func IsExecutable

func IsExecutable(path string) bool

func LookPath

func LookPath(file string) ([]string, error)

LookPath searches for an executable named file in the directories named by the PATH environment variable. If file contains a slash, it is tried directly and the PATH is not consulted. Otherwise, on success, the result is an absolute path.

In older versions of Go, LookPath could return a path relative to the current directory. As of Go 1.19, LookPath will instead return that path along with an error satisfying errors.Is(err, ErrDot). See the package documentation for more details.

func MustFindGit

func MustFindGit() string

Types

type LookPathError

type LookPathError struct {
	// Name is the file name for which the error occurred.
	Name string
	// Err is the underlying error.
	Err error
}

LookPathError is returned by LookPath when it fails to classify a file as an executable.

func (*LookPathError) Error

func (e *LookPathError) Error() string

func (*LookPathError) Unwrap

func (e *LookPathError) Unwrap() error
