Generic Parser
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 6
Abstract
This paper shows how to implement generic parsers as a family of streams. This allows for very readable, maintainable and flexible parsers. The method is illustrated with a parser for simple arithmetic expressions, but can easily be extended to a parser for a full-fledged programming language. Moreover, the same technique can be applied to the entire process from lexing to execution, since actions can be associated with each sub-parser. The parsing of input is a very important problem appearing in many different parts of software development - parsing user input in the form of command-line options, the parsing of arithmetic expressions in a calculator, parsing values in a user-defined configuration file or compiling some programming language. This makes it important to have different approaches. What we will present here in this project, is a method of parsing inspired by what is done in functional programming (FP). The paper is not about functional programming in C++. Moreover, the presence of too many parentheses makes the code harder to read and is hence also more error prone, rather it is about how to implement a particularly elegant idea from FP in an object oriented context.
