Types

type Context

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

func NewContext

func NewContext() *Context

func (*Context) Bind

func (c *Context) Bind(name skim.Symbol, value skim.Atom) *Context

func (*Context) BindProc

func (*Context) Dup

func (c *Context) Dup() *Context

Dup clones a context, flattening it into a single Context of known bindings and c's upvalues.

func (*Context) Parent

func (c *Context) Parent() *Context

func (*Context) Resolve

func (c *Context) Resolve(name skim.Symbol) (value skim.Atom, ok bool)

func (*Context) SetUpvalue

type Evaler interface {
	skim.Atom

	Eval(*Context, *skim.Cons) (skim.Atom, error)
}

type Proc
