func InitEnv(env *Env)

func InitEvalEnv 

func InitEvalEnv(env *Env, ee *EvalEnv, stackSize int)

Types

type DebugInfo 

type DebugInfo struct {
	Funcs map[*Func]FuncDebugInfo
}

func NewDebugInfo 

func NewDebugInfo() *DebugInfo

type Env 

type Env struct {
	NativeFuncs        []NativeFunc
	NameToNativeFuncID map[FuncKey]uint16

	UserFuncs    []*Func
	NameToFuncID map[FuncKey]uint16

	// debug contains all information that is only needed
	// for better debugging and compiled code introspection.
	// Right now it's always enabled, but we may allow stripping it later.
	Debug *DebugInfo
}

Env is used to hold both compilation and evaluation data.

func (*Env) AddFunc 

func (env *Env) AddFunc(pkgPath, funcName string, f *Func)

func (*Env) AddNativeFunc
