Types

type Stack

type Stack struct {
	Tables  []*tables.Table               `json:"tables"`
	Size    int                           `json:"size"`
	Imports map[string]*symbols.SymbolDef `json:"imports"`
}

Stack is a multi-level symbol table for parsing blocks of code

func (*Stack) LookupFromBlock

func (s *Stack) LookupFromBlock(name string, idx int) (*symbols.SymbolDef, symbols.SymbolType, error)

Lookup looks for the first occurrence of a symbol with the given name starting from a block idx

func (*Stack) LookupFunction

func (s *Stack) LookupFunction(name string) (*symbols.SymbolDef, error)

func (*Stack) LookupMethod

func (s *Stack) LookupMethod(datatype, methodName string) (*symbols.SymbolDef, error)

func (s *Stack) Pop()

Pop pops the top most symbol table from the stack

func (*Stack) Print

func (s *Stack) Print()

func (*Stack) PrintTop

func (s *Stack) PrintTop()

func (*Stack) Push

func (s *Stack) Push()

Push pushes a new symbol table at the top of the stack

func (*Stack) Reset
