Functions

func All

func All() map[string]Operator

func ApplyOperator(op Operator, node ast.Node, returnType string, file *ast.File, enclosingFunc *ast.FuncDecl) ast.Node

func ListCategories

func ListCategories() []string

func Register

func Register(op Operator)

Types

type Context

type Context struct {
	ReturnType    string
	FunctionName  string
	PackageName   string
	FileName      string
	Position      token.Position
	EnclosingFunc *ast.FuncDecl
	File          *ast.File
	Parent        ast.Node
}

type ContextualOperator

type ContextualOperator interface {
	Operator
	CanApplyWithContext(node ast.Node, ctx Context) bool
	MutateWithContext(node ast.Node, ctx Context) ast.Node
}

type Operator

type Operator interface {
	Name() string
	CanApply(node ast.Node) bool
	Mutate(node ast.Node) ast.Node
}

func Get

func Get(name string) (Operator, bool)

func GetCategory

func GetCategory(name string) ([]Operator, bool)

func List

func List() []Operator

func ListAll

func ListAll() []Operator

ListAll returns every registered operator regardless of selection. Used by sub-config resolution to map operator names to instances.

func MustGet

func MustGet(name string) Operator

type OperatorInitializer

type OperatorInitializer func() Operator

type OperatorRegistry

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

func NewOperatorRegistry

func NewOperatorRegistry() *OperatorRegistry

func (*OperatorRegistry) All

func (r *OperatorRegistry) All() map[string]Operator

func (*OperatorRegistry) Get

func (r *OperatorRegistry) Get(name string) (Operator, bool)

func (*OperatorRegistry) List

func (r *OperatorRegistry) List() []Operator

func (*OperatorRegistry) Register

func (r *OperatorRegistry) Register(op Operator)

func (*OperatorRegistry) RegisterInitializer

func (r *OperatorRegistry) RegisterInitializer(name string, init OperatorInitializer)

type TypeAwareOperator

type TypeAwareOperator interface {
	RequiresTypeCheck() bool
}
