type Message

type Message struct {
	Key    string         // original specified text: "Sig:label:"
	Name   string         // names are lower_underscore
	Labels []string       // parameter names sans colons

	Markup map[string]any // from map keys starting with "--"; stored stripped of the dashes.
}

Signatures start with a capital letter, and contain parameter names separated by colons. Markup keys start with a double dash.

func (*Message) AddMarkup

func (op *Message) AddMarkup(k string, v any)

type Unhandled

type Unhandled string

func (Unhandled) Error

func (u Unhandled) Error() string
