PVS-Studio continues a series of webinars on how to create your own programming language using C++. Previously, we discussed what a programming language is and its overall structure. This time, the talk host, Yuri Minaev, went a level deeper—into grammars. What's the talk about? A grammar consists of terminal and non-terminal symbols, production rules, and a starting point. Non-terminals define higher-level constructs in terms of other symbols, while terminals represent basic, indivisible elements like digits or characters. Yuri explains how the way you design grammar determines how expressions are parsed and evaluated, including the associativity and priority of operations. He also introduces recursive definitions and explains how they form tree-like structures during parsing. The webinar wraps up by connecting grammar theory to actual implementation, describing recursive descent parsing as a flexible and an easy to implement approach.…
