In formal grammar theory, the deterministic context-free grammars (DCFGs) are a proper subset of the context-free grammars. They are the subset of context-free grammars that can be derived from deterministic pushdown automata, and they generate the deterministic context-free languages. DCFGs are always unambiguous, and are an important subclass of unambiguous CFGs; there are non-deterministic unambiguous CFGs, however. DCFGs are of great practical interest, as they can be parsed in linear time and in fact a parser can be automatically generated from the grammar by a parser generator. They are thus widely used throughout computer science. Various restricted forms of DCFGs can be parsed by simpler, less resource-intensive parsers, and thus are often used. These grammar classes are referred to by the type of parser that parses them, and important examples are LALR, SLR, and LL. (Wikipedia).

7.1: Intro to Session 7: Context-Free Grammar - Programming with Text
This video introduces Session 7: Context-Free Grammar from the ITP course "Programming from A to Z". A Context-Free Grammar is a set of recursive "replacement" rules to generate text. In this session, I discuss two JavaScript libraries: Tracery and RiTa.js for working with context-free gr
