	Examples []AnnotatedExample

	Fields FieldSpecs
}

ComponentSpec describes a Benthos component.

func (*ComponentSpec) AsMarkdown

func (c *ComponentSpec) AsMarkdown(nest bool, fullConfigExample interface{}) ([]byte, error)

AsMarkdown renders the spec of a component, along with a full configuration example, into a markdown document.

type FieldInterpolation

type FieldInterpolation int

FieldInterpolation represents a type of interpolation supported by a field.

const (
	FieldInterpolationNone FieldInterpolation = iota
	FieldInterpolationBatchWide
	FieldInterpolationIndividual
)

Interpolation types.

type FieldSpec

type FieldSpec struct {
	// Name of the field (as it appears in config).
	Name string

	// Description of the field purpose (in markdown).
	Description string

	// Advanced is true for optional fields that will not be present in most
	// configs.
	Advanced bool

	// Deprecated is true for fields that are deprecated and only exist for
	// backwards compatibility reasons.
	Deprecated bool

	// Default value of the field. If left nil the docs generator will attempt
	// to infer the default value from an example config.
	Default interface{}

	// Type of the field. This is optional and doesn't prevent documentation for
	// a field.
	Type FieldType

	// Interpolation indicates the type of interpolation that this field
	// supports.
	Interpolation FieldInterpolation

	// Examples is a slice of optional example values for a field.
	Examples []interface{}

	// AnnotatedOptions for this field. Each option should have a summary.
	AnnotatedOptions [][2]string

	// Options for this field.
	Options []string

	// Children fields of this field (it must be an object).
	Children FieldSpecs
}

FieldSpec describes a component config field.
