Types

type Field

type Field interface {
	GetKey() string                        // Key for the data map.
	GetLabel() string                      // Label to print as the prompt.
	GetLabelExtra() string                 // Extra info for the label, eg. defaults.
	GetContents(io.Reader) (string, error) // Read the field contents from the supplied reader

	// Sanitize user input and return the field's native type.
	Clean(s string) (interface{}, error)
}

A Field in a form.

type Form

type Form struct {
	Banner string
	Fields []Field
}

A Form used to handle user interactions.

func (Form) Run

func (f Form) Run(r io.Reader, w io.Writer) (map[string]interface{}, error)

Run executes the form against the specified input and output.

type PasswordField

type PasswordField struct {
	Key   string
	Label string
	Min   int
}

PasswordField masks password input

func (PasswordField) Clean

func (f PasswordField) Clean(s string) (interface{}, error)

Clean just checks if the minimum length is exceeded, it doesn't trim the string!

func (PasswordField) GetContents

func (f PasswordField) GetContents(r io.Reader) (string, error)

GetContents simply reads a string in cleartext from the supplied reader

func (PasswordField) GetKey

func (f PasswordField) GetKey() string

GetKey returns the field's key

func (PasswordField) GetLabel

func (f PasswordField) GetLabel() string

GetLabel returns the field's label

func (PasswordField) GetLabelExtra

func (f PasswordField) GetLabelExtra() string

GetLabelExtra doesn't return anything so we don't expose the current password

type ProgressBar

type ProgressBar struct {
	Width       int
	Progress    float64
	Left, Right func() string
}

func (ProgressBar) String

func (b ProgressBar) String() string

type StringField

type StringField struct {
	Key     string
	Label   string
	Default string

	// Length constraints.
	Min, Max int
}

StringField is just a simple field for reading cleartext strings

func (StringField) Clean

func (f StringField) Clean(s string) (interface{}, error)

Clean trims the spaces in the string and checks for min and max length

func (StringField) GetContents

func (f StringField) GetContents(r io.Reader) (string, error)

GetContents simply reads a string in cleartext from the supplied reader It's compllicated and doesn't use t he bufio utils because we can't read ahead of the newline and consume more of the stdin, because we'll mess up the next form field

func (StringField) GetKey

func (f StringField) GetKey() string

GetKey returns the field's key

func (StringField) GetLabel

func (f StringField) GetLabel() string

GetLabel returns the field's label

func (StringField) GetLabelExtra

func (f StringField) GetLabelExtra() string

GetLabelExtra returns the field's default value

type SummaryData

type SummaryData struct {
	Opts    lib.Options
	Root    *lib.Group
	Metrics map[string]*stats.Metric
	Time    time.Duration
}

SummaryData represents data passed to Summarize.

type TrendColumn

type TrendColumn struct {
	Key string
	Get func(s *stats.TrendSink) float64
}
