Variables

var DisableColor = false

DisableColor can be used to make testing reliable

var TemplateFuncsNoColor = map[string]interface{}{

	"color": func(color string) string {
		return ""
	},
}

var TemplateFuncsWithColor = map[string]interface{}{

	"color": ansi.ColorCode,
}

Functions

func IsFieldNotMatch

func IsFieldNotMatch(err error) (string, bool)

IsFieldNotMatch reports whether an "err" is caused by a non matching field. It returns the Question.Name that couldn't be matched with a destination field.

Usage: err := survey.Ask(qs, &v);

if err != nil {
	if name, ok := core.IsFieldNotMatch(err); ok {
		[...name is the not matched question name]
	}
}

func RunTemplate

func RunTemplate(tmpl string, data interface{}) (string, string, error)

RunTemplate returns two formatted strings given a template and the data it requires. The first string returned is generated for user-facing output and may or may not contain ANSI escape codes for colored output. The second string does not contain escape codes and can be used by the renderer for layout purposes.

func WriteAnswer

func WriteAnswer(t interface{}, name string, v interface{}) (err error)
