This book discusses the concept of the basics of formal language and compilation. This book presents the subject in a minimalist way clear, reader-friendly and simple, presenting the principles and methods used to define the syntax of an artificial language and to implement a simple interpreter, as well as in designing the syntax-directed translator. Features: unify concepts and notations used in a variety of approaches parsing algorithms; concepts are illustrated with realistic examples of many, to facilitate understanding of the theory and the transfer to the application; theoretical models of automata, transducers and formal grammar is used widely; algorithms described in pseudo-code to avoid disturbing details of a programming language, but they are easy to convert to the execution procedure; problems and solutions are available through the author's site. This text is comprehensive and clearly written to be welcomed by graduate students as an ideal guide to the basics of this field.
