Types ¶
type Config ¶
type Config struct {
Fset *token.FileSet
Scanner *goscan.Scanner
Registry *object.SymbolRegistry
SpecialForms map[string]*SpecialForm
Packages map[string]*object.Package
Stdin io.Reader
Stdout io.Writer
Stderr io.Writer
}
Config holds the configuration for creating a new Evaluator.
type Evaluator ¶
type Evaluator struct {
object.BuiltinContext
// contains filtered or unexported fields
}
Evaluator is the main object that evaluates the AST.
func (*Evaluator) ApplyFunction ¶
func (e *Evaluator) ApplyFunction(call *ast.CallExpr, fn object.Object, args []object.Object, fscope *object.FileScope) object.Object
ApplyFunction is a public wrapper for the internal applyFunction, allowing it to be called from other packages.
func (*Evaluator) EvalToplevel ¶
func (e *Evaluator) EvalToplevel(decls []object.DeclWithScope, env *object.Environment) object.Object
EvalToplevel orchestrates the two-pass evaluation for a set of declarations from one or more files.
type SpecialForm ¶
type SpecialForm struct {
Fn SpecialFormFunction
}
SpecialForm represents a special form function.
func (*SpecialForm) Inspect ¶
func (sf *SpecialForm) Inspect() string
Inspect returns a string representation of the special form function.
func (*SpecialForm) Type ¶
func (sf *SpecialForm) Type() object.ObjectType
Type returns the type of the SpecialForm object.
