Types

type Appearance

type Appearance struct {
	TypeName  string
	FieldName string
}

Appearance of a type in a different type.

type CommentsFlags

type CommentsFlags int

CommentsFlags comments encoding flags type.

const (
	// CommentsDisabled renders no comments.
	CommentsDisabled CommentsFlags = 0
	// CommentsExamples enables commented yaml examples rendering.
	CommentsExamples CommentsFlags = 1 << iota
	// CommentsDocs enables rendering each config field short docstring.
	CommentsDocs
	// CommentsAll renders all comments.
	CommentsAll = CommentsExamples | CommentsDocs
)

type Doc

type Doc struct {
	// Comments stores foot, line and head comments.
	Comments [3]string
	// Fields contains fields documentation if related item is a struct.
	Fields []Doc
	// Examples list of example values for the item.
	Examples []*Example
	// Values is only used to render valid values list in the documentation.
	Values []string
	// Description represents the full description for the item.
	Description string
	// Name represents struct name or field name.
	Name string
	// Type represents struct name or field type.
	Type string
	// Note is rendered as a note for the example in markdown file.
	Note string
	// AppearsIn describes back references for the type.
	AppearsIn []Appearance
}

Doc represents a struct documentation rendered from comments by docgen.

func (*Doc) AddExample

func (d *Doc) AddExample(name string, value interface{})

AddExample adds a new example snippet to the doc.

func (*Doc) Describe

func (d *Doc) Describe(field string, short bool) string

Describe returns a field description.

func (*Doc) Field

func (d *Doc) Field(i int) *Doc

Field gets field from the list of fields.

type Documented

type Documented interface {
	// Doc requests documentation object.
	Doc() *Doc
}

Documented is used to check if struct has any documentation defined for it.

type Encoder

type Encoder struct {
	// contains filtered or unexported fields
}

Encoder implements config encoder.

func NewEncoder

func NewEncoder(value interface{}, opts ...Option) *Encoder

NewEncoder initializes and returns an `Encoder`.

func (*Encoder) Encode

func (e *Encoder) Encode() ([]byte, error)

Encode converts value to yaml.

func (*Encoder) Marshal

func (e *Encoder) Marshal() (*yaml.Node, error)

Marshal converts value to YAML-serializable value (suitable for MarshalYAML).

type Example

type Example struct {
	Name string
	// contains filtered or unexported fields
}

Example represents one example snippet for a type.

func (*Example) GetValue

func (e *Example) GetValue() interface{}

GetValue returns example value.

func (*Example) Populate

func (e *Example) Populate(index int)

	Name string
	// Description file description, supports markdown.
	Description string
	// Structs structs defined in the file.
	Structs []*Doc
	// Types is map of all non-trivial types defined in the file.
	Types map[string]*Doc
}

FileDoc represents a single go file documentation.
