Functions

func CheckFilenameValidity

func CheckFilenameValidity(filename string) error

CheckFilenameValidity checks if a filename is valid. If it is not, returns an error.

func ConsoleCancelableContext

func ConsoleCancelableContext() context.Context

ConsoleCancelableContext creates a context that can be canceled from the console. For example, by typing Ctrl + C.

func ReadableMemorySize

func ReadableMemorySize(bytes uint64) string

ReadableMemorySize returns a prettier form of some memory size expressed in bytes. Note: Do not exceed the float64 limit, as the result will overflow.

func ResolveURL

func ResolveURL(rawURL string) (string, error)

ResolveURL resolves the rawURL adding the http prefix, preferring https over http.
