ArithmeticParser

Very Simple Proof of Concept Parser for Simple Arithmetic Expressions.

Build Status NuGet package

This is an example of Recursive Descent Parser which builds an Abstract Syntax Tree.

It also illustrates the usage of the Visitor Pattern to traverse the Syntax Tree.

Supported Operations:

  • Binary Operations
    • Addition
    • Subtraction
    • Multiplication
    • Division
    • Modula
    • Power
  • Function Calls
  • Variables
    • Constants

Sample Vistors include:

  • CalculateVisitor: calculates the result of the arithmetic expression as a double.
  • Parenthesizer: Several Visitors to create infix notation from a syntax tree.
  • RPN: Output as a postfix syntax tree also known as reverse polish notation
  • GraphViz: Visualize parse tree with GraphViz

Example 1

Some Simple Tests are included, but no exhaustive test suite, the Parser is intendet only as an academic example with a well designed architecture.
