Overview ¶
Package interp evaluates GX code given an evaluator.
All values in the interpreter are represented in elements. The GX Context evaluates GX code represented as an intermediate representation (IR) tree (see github.com/gx-org/gx/build/ir), evaluates a function given a receiver and arguments passed as interpreter elements.

Functions ¶
func EvalExprInContext ¶
EvalExprInContext uses an evaluator to evaluation an IR expression.
func EvalFunc ¶
func EvalFunc(eval evaluator.Evaluator, fn *ir.FuncDecl, in *elements.InputElements, options []options.PackageOption) (outs []elements.Element, err error)
EvalFunc evaluates a function.
func NewRunFunc ¶
NewRunFunc creates a function given an IR and a receiver. The function is run when being called.
func ToSingleElement ¶
func ToSingleElement(ctx elements.FileContext, node ir.SourceNode, els []elements.Element) (elements.Element, error)
ToSingleElement packs multiple elements into a tuple. If the slice els contains only one element, this element is returned.
Types ¶
type EvalContext ¶
type EvalContext struct {
// contains filtered or unexported fields
}
EvalContext returns the context for the interpreter.
func NewInterpContext ¶
func NewInterpContext(eval evaluator.Evaluator, options []options.PackageOption) (*EvalContext, error)
NewInterpContext returns a new interpreter context.
func (*EvalContext) Evaluator ¶
func (eval *EvalContext) Evaluator() evaluator.Evaluator
Evaluator returns the evaluator used by in evaluations.
func (*EvalContext) NewFileContext ¶
NewFileContext returns a context for a given file.
