Functions

func BytesToString 

func BytesToString(bytes []byte) string

This conversion *does not* copy data. Note that converting via "(string)([]byte)" *does* copy data. Also note that you *should not* change the byte slice after conversion, because Go strings are treated as immutable. This would cause a segmentation violation panic.

func ContextualRead added in v0.2.2 

func ContextualRead(context contextpkg.Context, reader io.Reader, p []byte) (int, error)

func CopySSH 

func CopySSH(host string, port int, username string, key string, reader io.Reader, targetPath string, permissions *int64) error

Generates a random RSA key pair and uses it to sign a X.509 certificate with a random serial number.

If host is empy it will default to "localhost". If rsaBits is 0 it will default to 2048. If duration is 0 it will default to one year.

func CreateSelfSignedTLSConfig added in v0.1.38 

func CreateSelfSignedTLSConfig(organization string, host string, rsaBits int, duration time.Duration) (*tls.Config, error)

Creates a TLS config with a single X.509 certificate signed with a new RSA key pair.

If rsaBits is 0 it will default to 2048. If duration is 0 it will default to one year.

func InitializeColorization(colorize string)

Attempts to enable colorization for os.Stdout and os.Stderr according to the colorize argument. If cleanup is required, will set register it with OnExit. Errors will Fail.

The colorize argument can be:

  • "true", "TRUE", "True", "t", "T", "1": Attempts to enable colorization if os.Stdout and os.Stdout support it. If it succeeds will set [ColorizeStdout], [StdoutStylist], [ColorizeStderr], and [StderrStylist] accordingly.
  • "false", "FALSE", "False", "f", "F", "0": Does nothing.
  • "force": Sets [ColorizeStdout], [StdoutStylist], [ColorizeStderr], and [StderrStylist] as if coloriziation were enabled.

func StringToBytes 

func StringToBytes(string_ string) (bytes []byte)

This conversion *does not* copy data. Note that converting via "([]byte)(string)" *does* copy data. Also note that you *should not* change the byte slice after conversion, because Go strings are treated as immutable. This would cause a segmentation violation panic.

func ToBase64 added in v0.1.4 

func ToBase64(bytes []byte) string

func ToBroadcastIPAddress added in v0.1.60 

func ToBroadcastIPAddress(address string) (string, error)

The argument is validated as being a multicast address, e.g. "ff02::1" (IPv6) or "239.0.0.1" (IPv4). For IPv6, if it does not include a zone, a valid zone will be added by enumerating the active local interfaces, chosing one arbitrarily.

func ToReachableIPAddress added in v0.1.60 

func ToReachableIPAddress(address string) (string, error)

Always returns a specified address. If the argument is already a specified address, returns it as is. Otherwise (when it's "::" or "0.0.0.0") will attempt to find a specified address by enumerating the active local interfaces, chosing one arbitrarily, with a preference for a global unicast address.

The IP version of the returned address will match that of the argument, IPv6 for "::" and IPv4 for "0.0.0.0".

Note that a returned IPv6 address may include a zone (when not a global unicast).

func ToSnakeCase added in v0.1.61 

func ToSnakeCase(name string) string

func WriteNewline(writer io.Writer) error

func WriteTLSCertificatePEM added in v0.3.13

Types

type BufferedWriter added in v0.1.22 

type BufferedWriter struct {
	// contains filtered or unexported fields
}

func NewBufferedWriter added in v0.1.22 

func NewBufferedWriter(writer io.Writer, size int, copy bool) *BufferedWriter

Creates a thread-safe io.WriterCloser that separates the acceptance of byte slices via BufferedWriter.Write from the actual writing of the data to the underlying io.Writer, which occurs on a separate goroutine.

The size argument is for the internal channel, referring to the maximum number of write submissions to be buffered (not the number of bytes). If the buffering channel is full then BufferedWriter.Write will return an error. The actual write errors are ignored.

When copy is true the implementation copies the byte slice before sending it to the separate goroutine. This ensures that the submitted data is indeed the data that will be written, even if the underlying array changes after submission.

func (*BufferedWriter) Close added in v0.1.22 

func (self *BufferedWriter) Close() error

(io.Reader interface)

func NewChannelWriter added in v0.1.57 

func NewChannelWriter(ch chan []byte, copy bool) *ChannelWriter

Creates an io.Writer that writes bytes to a channel. The expectation is that something else will be receiving from the channel and processing the bytes. Writing is non-blocking: if the channel is full then ChannelWriter.Write will return an error.

When copy is true the implementation copies the byte slice before sending it to the channel. This ensures that the submitted data is indeed the data that will be received, even if the underlying array changes after submission.

func (*ChannelWriter) Write added in v0.1.57 

func (self *ChannelWriter) Write(p []byte) (int, error)
