Types

type Engine

type Engine struct {
	*tpl.CompileRet
	Interpreter interpreter.Interface
	// contains filtered or unexported fields
}

Engine represents an interpreter.

func New

func New(ipt interpreter.Interface, options *Options) (p *Engine, err error)

New creates an interpreter.

func (*Engine) EvalCode

func (p *Engine) EvalCode(fn interpreter.Interface, name string, src interface{}) error

EvalCode evals src code.

func (*Engine) FileLine

func (p *Engine) FileLine(src interface{}) (f interpreter.FileLine)

FileLine returns file name and line number of src.

func (*Engine) Source

func (p *Engine) Source(src interface{}) (text []byte)

Source returns the source text of src.

type Options

type Options struct {
	Scanner  tpl.Tokener
	ScanMode tpl.ScanMode
}

Options is options of an interpreter.

type RuntimeError
