ANTLR4 Example

This project contains four examples of simple calculator grammar:

• Calc.g4 contains just grammar without any actions attached
• CalcSemantic.g4 contains grammar with semantic actions allowing to compute the result of expression
• CalcPatters.g4 is a variant of grammar with rules labels for use with Listener and Visitor patterns
  • for Listener pattern please check CalcListenerImpl implementation
  • for Visitor pattern please check CalcVisitorImpl implementation

Each example has its corresponding test in ANTLRExampleTest class
