Learn to build configuration file readers, data readers, model driven code generators, source to source translators, source analyzers, and interpreters You don t need a background in computer science ANTLR creator Terence Parr demystifies language implementation by breaking it down into the most common design patterns Pattern by pattern, you ll learn the key skills you need to implement your own computer languagesKnowing how to create domain specific languages DSLs can give you a huge productivity boost Instead of writing code in a general purpose programming language, you can first build a custom language tailored to make you efficient in a particular domainThe key is understanding the common patterns found across language implementations Language Design Patterns identifies and condenses the most common design patterns, providing sample implementations of eachThe pattern implementations use Java, but the patterns themselves are completely general Some of the implementations use the well known ANTLR parser generator, so readers will find this book an excellent source of ANTLR examples as well But this book will benefit anyone interested in implementing languages, regardless of their tool of choice Other language implementation books focus on compilers, which you rarely need in your daily life Instead, Language Design Patterns shows you patterns you can use for all kinds of language applicationsYou ll learn to create configuration file readers, data readers, model driven code generators, source to source translators, source analyzers, and interpreters Each chapter groups related design patterns and, in each pattern, you ll get hands on experience by building a complete sample implementation By the time you finish the book, you ll know how to solve most common language implementation problems
