Overview

Package object provides the standard set of Risor object types.

For external users of Risor, often an object.Object interface will be type asserted to a specific object type, such as *object.Float.

For example: 

switch obj := obj.(type) {
case *object.String:
	// do something with obj.Value()
case *object.Float:
	// do something with obj.Value()
}

The Type() method of each object may also be used to get a string name of the object type, such as "string" or "float".

Functions

func AsIterator added in v0.10.0 

func AsIterator(obj Object) (Iterator, *Error)

func AsList 

func AsList(obj Object) (*List, *Error)

func AsMap 

func AsMap(obj Object) (*Map, *Error)

func AsObjects added in v0.14.0 

func AsObjects(m map[string]any) (map[string]Object, error)

AsObjects transform a map containing arbitrary Go types to a map of Risor objects, using the best type converter for each type. If an item in the map is of a type that can't be converted, an error is returned.

func AsSet 

func AsSet(obj Object) (*Set, *Error)

func CompareTypes 

func CompareTypes(a, b Object) int

func Equals 

func Equals(a, b Object) bool

func IsError

func Keys added in v0.14.0 

func Keys(m map[string]Object) []string

Keys returns the keys of an object map as a sorted slice of strings.

func NewArgumentsError 

func NewArgumentsError(message string, args ...interface{}) error

func ResolveIndex 

func ResolveIndex(idx int64, size int64) (int64, error)

ResolveIndex checks that the index is inbounds and transforms a negative index into the corresponding positive index. If the index is out of bounds, an error is returned.

func ResolveIntSlice 

func ResolveIntSlice(slice Slice, size int64) (start int64, stop int64, err error)

ResolveIntSlice checks that the slice start and stop indices are inbounds and transforms negative indices into the corresponding positive indices. If the slice is out of bounds, an error is returned.

func SetTypeConverter 

func SetTypeConverter(typ reflect.Type, conv TypeConverter)

SetTypeConverter sets a TypeConverter for the given Go type. This is not typically used, since the default converters should typically be sufficient.

func WithCallFunc 

func WithCallFunc(ctx context.Context, fn CallFunc) context.Context

WithCallFunc adds an CallFunc to the context, which can be used by objects to call a Risor function at runtime.

func WithCloneCallFunc added in v1.4.0 

func WithCloneCallFunc(ctx context.Context, fn CallFunc) context.Context

WithCloneCallFunc returns a context with a "clone-call" function associated. This function can be used to clone a Risor VM and then call a function on it synchronously.

func WithSpawnFunc added in v1.4.0 

func WithSpawnFunc(ctx context.Context, fn SpawnFunc) context.Context

WithSpawnFunc adds an SpawnFunc to the context, which can be used by objects to spawn themselves.

Type constants

type TypeConverter 

type TypeConverter interface {
	// To converts to a Go object from a Risor object.
	To(Object) (interface{}, error)

	// From converts a Go object to a Risor object.
	From(interface{}) (Object, error)
}

TypeConverter is an interface used to convert between Go and Risor objects for a single Go type.

func NewTypeConverter 

func NewTypeConverter(typ reflect.Type) (TypeConverter, error)

NewTypeConverter returns a TypeConverter for the given Go kind and type. Converters are cached internally for reuse.
