template

type Template ¶

type Template interface {
	Execute(grokValues map[string]string) (string, error)
	ReferencedGrokFields() []string
	Name() string
}

Works like golang's text/template, but additionally provides the list of referenced fields. Example: "{{if eq .field1 .field2}}{{.field3}}{{end}}" Executing this template is similar to text/template.Template.Execute(), and ReferencedGrokFields() yields {"field1", "field2", "field3"}

func New(name, template string) (Template, error)
