Functions

func CoreConsts

func CoreConsts() *vm.Consts

CoreConsts returns the global const pool populated during core boot. Used as parent for layered child pools during user code compilation.

func Eval

func Eval(src string) (vm.Value, error)

func PrecompiledNSChunk

func PrecompiledNSChunk(name string) *vm.CodeChunk

PrecompiledNSChunk returns the precompiled main chunk for a namespace, or nil.

func ReadString

func ReadString(s string) (vm.Value, error)

ReadString parses a string into a let-go Value.

Types

type CompileError

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

func NewCompileError

func NewCompileError(message string) *CompileError
