Types

type BuffPrinter

type BuffPrinter struct {
	Buff         *strings.Builder
	BuffOutPrint func(s string)
	BuffErrPrint func(s string)
}

BuffPrinter implements the console.Printer interface that writes to a buffer.

func NewBufferPrinter

func NewBufferPrinter() *BuffPrinter

func (*BuffPrinter) Error

func (b *BuffPrinter) Error(s string)

Error writes s to a buffer.

func (*BuffPrinter) Format

func (b *BuffPrinter) Format() []string

func (*BuffPrinter) Log

func (b *BuffPrinter) Log(s string)

Log writes s to a buffer.

func (*BuffPrinter) Warn

func (b *BuffPrinter) Warn(s string)

Warn writes s to a buffer.

type Transformer

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

func NewTransformer

func NewTransformer(r *goja.Runtime) *Transformer

func (*Transformer) RunStringUnsafe

func (t *Transformer) RunStringUnsafe(function string, payload interface{}) (interface{}, []string, error)

func (*Transformer) Transform

func (t *Transformer) Transform(function string, payload interface{}) (interface{}, []string, error)

Transform mutates the payload by the passed function The output of Transform should be idempotent

func (*Transformer) TransformUsingUnderscoreJs

func (t *Transformer) TransformUsingUnderscoreJs(function string, payload interface{}) (interface{}, []string, error)

TransformUsingUnderscoreJs downloads the underscore js library and then mutates the payload by the passed function. The output of TransformUsingUnderscoreJs should be idempotent
