var ErrPasteIndicator = pasteIndicatorError{}

ErrPasteIndicator may be returned from ReadLine as the error, in addition to valid line data. It indicates that bracketed paste mode is enabled and that the returned line consists only of pasted data. Programs may wish to interpret pasted data more literally than typed data.

type AsciiWriter 

type AsciiWriter struct {

	TimestampNano int64
	// contains filtered or unexported fields
}

func NewWriter 

func NewWriter(w io.Writer, opts ...AsciiOption) *AsciiWriter

func (*AsciiWriter) WriteHeader 

func (w *AsciiWriter) WriteHeader() error

func (*AsciiWriter) WriteRow 

func (w *AsciiWriter) WriteRow(p []byte) error

func (*AsciiWriter) WriteStdout 

func (w *AsciiWriter) WriteStdout(ts float64, data []byte) error

type Env 

type Env struct {
	Shell string `json:"SHELL"`
	Term  string `json:"TERM"`
}

type EscapeCodes 

type EscapeCodes struct {
	// Foreground colors
	Black, Red, Green, Yellow, Blue, Magenta, Cyan, White []byte

	// Reset all attributes
	Reset []byte
}

EscapeCodes contains escape sequences that can be written to the terminal in order to achieve different styles of text. 

type Header struct {
	Version   int    `json:"version"`
	Width     int    `json:"width"`
	Height    int    `json:"height"`
	Timestamp int64  `json:"timestamp"`
	Title     string `json:"title"`
	Env       Env    `json:"env"`
}

type Terminal 

type Terminal struct {
	// AutoCompleteCallback, if non-null, is called for each keypress with
	// the full input line and the current position of the cursor (in
	// bytes, as an index into |line|). If it returns ok=false, the key
	// press is processed normally. Otherwise it returns a replacement line
	// and the new cursor position.
	AutoCompleteCallback func(line string, pos int, key rune) (newLine string, newPos int, ok bool)

	// Escape contains a pointer to the escape codes for this terminal.
	// It's always a valid pointer, although the escape codes themselves
	// may be empty if the terminal doesn't support them.
	Escape *EscapeCodes
	// contains filtered or unexported fields
}

Terminal contains the state for running a VT100 terminal that is capable of reading lines of input.

func NewTerminal 

func NewTerminal(c io.ReadWriter, prompt string) *Terminal

NewTerminal runs a VT100 terminal on the given ReadWriter. If the ReadWriter is a local terminal, that terminal must first have been put into raw mode. prompt is a string that is written at the start of each input line (i.e. "> ").

func (*Terminal) GetSize 

func (t *Terminal) GetSize() (width, height int)

func (*Terminal) ReadLine 

func (t *Terminal) ReadLine() (line string, err error)

ReadLine returns a line of input from the terminal.

func (*Terminal) ReadLines 

func (t *Terminal) ReadLines() (lines []string, err error)

func (*Terminal) ReadPassword 

func (t *Terminal) ReadPassword(prompt string) (line string, err error)

ReadPassword temporarily changes the prompt and reads a password, without echo, from the terminal.

func (*Terminal) SetBracketedPasteMode 

func (t *Terminal) SetBracketedPasteMode(on bool)

SetBracketedPasteMode requests that the terminal bracket paste operations with markers. Not all terminals support this but, if it is supported, then enabling this mode will stop any autocomplete callback from running due to pastes. Additionally, any lines that are completely pasted will be returned from ReadLine with the error set to ErrPasteIndicator.

func (*Terminal) SetEcho 

func (t *Terminal) SetEcho(echo bool)

func (*Terminal) SetPrompt 

func (t *Terminal) SetPrompt(prompt string)

SetPrompt sets the prompt to be used when reading subsequent lines.

func (t *Terminal) SetSize(width, height int) error

func (*Terminal) Write 

func (t *Terminal) Write(buf []byte) (n int, err error)

type WrapperTable 

type WrapperTable struct {
	Labels      []string
	Fields      []string
	FieldsSize  map[string][3]int // 列宽，列最小宽，列最大宽
