Types

type Action 

type Action struct {
	Action    string
	Arguments []call.Arg
	Markup    map[string]any
}

Run a script defined action. The action will be parameterized with the actor performing the action, and up to two other nouns. The actor is always the player's, the nouns are whichever were matched by Noun. This command usually appears last in a series of sub-scanners, after all of the earlier scanners have successfully matched.

func (*Action) GetMarkup 

func (op *Action) GetMarkup(ensure bool) map[string]any

Implements typeinfo.Markup

func (*Action) MakeScanner

type ChooseOne 

type ChooseOne struct {
	Options []ScannerMaker
	Markup  map[string]any
}

type Directive 

type Directive struct {
	Name   string
	Series []ScannerMaker
	Markup map[string]any

Starts a parser scanner. This is generated by story statement "DefineNamedGrammar" so that grammar doesn't have to import weave.

type Focus 

type Focus struct {
	Player string
	Series []ScannerMaker
	Markup map[string]any
}

Select a specific set of bounds for the scanner to use when matching nouns. Currently, the set of scanners is defined in golang, and cannot be extended by script. They are:

  • "" - the empty string for the current locale ( the default bounds )
  • "compass" - for nouns of kind "directions" ( north, east, etc. )
  • "player" - for the player's inventory
  • "debugging" - for all objects of kind "objects"

type Noun 

type Noun struct {
	Kind   string
