Functions

func EncodeQuoted

func EncodeQuoted(t string) string

EncodeQuoted encodes a string into a series of quoted 255-octet chunks. That is, when decoded each chunk would be 255-octets with the remainder in the last chunk.

The output looks like:

`""`                                      empty
`"255\"octets"`                           quotes are escaped
`"255\\octets"`                           backslashes are escaped
`"255octets" "255octets" "remainder"`     long strings are chunked

func ParseQuoted

func ParseQuoted(s string) (string, error)

ParseQuoted parses a string of RFC1035-style quoted items. The resulting items are then joined into one string. This is useful for parsing TXT records. Examples: `foo` => foo `"foo"` => foo `"f\"oo"` => f"oo `"f\\oo"` => f\oo `"foo" "bar"` => foobar `"foo" bar` => foobar

func ToChunks

func ToChunks(s string) []string

ToChunks returns the string as chunks of 255-octet strings (the last string being the remainder).

Types

type State

type State int

State denotes the parser state.

const (
	// StateStart indicates parser is looking for a non-space
	StateStart State = iota

	// StateUnquoted indicates parser is in a run of unquoted text
	StateUnquoted

	// StateQuoted indicates parser is in quoted text
	StateQuoted

	// StateBackslash indicates the last char was backlash in a quoted string
	StateBackslash

	// StateWantSpace indicates parser expects a space (the previous token was a closing quote)
	StateWantSpace
)

func (State) String

func (i State) String() string
