Function GetBaseFileName

internal/tspath/path.go:840–853

Gets the portion of a path following the last (non-terminal) separator (`/`). Semantics align with NodeJS's `path.basename` except that we support URL's as well. If the base name has any one of the provided extensions, it is removed. // POSIX GetBaseFileName("/path/to/file.ext") == "file.ext" Ge

(path string)

//	GetBaseFileName("file:///") == ""
//	GetBaseFileName("file://") == ""
func GetBaseFileName(path string) string {
	path = NormalizeSlashes(path)

	// if the path provided is itself the root, then it has no file name.
	rootLength := GetRootLength(path)
	if rootLength == len(path) {
		return ""
	}

	// return the trailing portion of the path starting after the last (non-terminal) directory
	// separator but not including any trailing directory separator.
	path = RemoveTrailingDirectorySeparator(path)
	return path[max(GetRootLength(path), strings.LastIndex(path, string(DirectorySeparator))+1):]
}

// Gets the file extension for a path.
// If extensions are provided, gets the file extension for a path, provided it is one of the provided extensions.
