Function UnmarshalModule

caddyconfig/caddyfile/adapter.go:127–142

UnmarshalModule instantiates a module with the given ID and invokes UnmarshalCaddyfile on the new value using the immediate next segment of d as input. In other words, d's next token should be the first token of the module's Caddyfile input. This function is used when the next segment of Caddyfile

(d *Dispenser, moduleID string)

// type-asserted to the module's associated type for practical use
// when setting up a config.
func UnmarshalModule(d *Dispenser, moduleID string) (Unmarshaler, error) {
	mod, err := caddy.GetModule(moduleID)
	if err != nil {
		return nil, d.Errf("getting module named '%s': %v", moduleID, err)
	}
	inst := mod.New()
	unm, ok := inst.(Unmarshaler)
	if !ok {
		return nil, d.Errf("module %s is not a Caddyfile unmarshaler; is %T", mod.ID, inst)
	}
	err = unm.UnmarshalCaddyfile(d.NewFromNextSegment())
	if err != nil {
		return nil, err
	}
