Overview

Package util is forked from https://github.com/qri-io/starlib in order to prune excessive transitive dependencies from pulling in that library.

Functions

func IsEmptyString

func IsEmptyString(s starlark.String) bool

IsEmptyString checks is a starlark string is empty ("" for a go string) starlark.String.String performs repr-style quotation, which is necessary for the starlark.Value contract but a frequent source of errors in API clients. This helper method makes sure it'll work properly

func Marshal

func Marshal(data interface{}) (v starlark.Value, err error)

Marshal turns go values into starlark types

func Unmarshal

func Unmarshal(x starlark.Value) (val interface{}, err error)

Unmarshal decodes a starlark.Value into it's golang counterpart

Types

type Marshaler

type Marshaler interface {
	// MarshalStarlark marshal a custom type to starlark object.
	MarshalStarlark() (starlark.Value, error)
}

Marshaler is the interface use to marshal starlark custom types.

type Unmarshaler

type Unmarshaler interface {
	// UnmarshalStarlark unmarshal a starlark object to custom type.
	UnmarshalStarlark(starlark.Value) error
}

Unmarshaler is the interface use to unmarshal starlark custom types.
