WebThere are many ways we could implement this parser. Here, we’ll use a “recursive descent” parsing technique. It’s the most common type because it’s the simplest to understand and implement. A recursive descent parser uses one function for each nonterminal in the grammar. It starts from the starting rule and goes down from there (hence ... WebA Bison file has three parts. In the first part, the prologue, we start by making sure we run a version of Bison which is recent enough, and that we generate C++. %require "3.2" %language "c++". Let’s dive directly into the middle part: the grammar. Our input is a simple list of strings, that we display once the parsing is done.
