Torben Ægidius Mogensen's "Basics of Compiler Design, Chapter 1: Introduction"
Read section 1.4, which gives reasons for studying compilers. In the discussion, the author suggests other applications for compiler techniques and tools. He specifically mentions domain-specific languages. Other applications derive from techniques and methods used in compilers. For example, if the input to a software system can be described using a formal grammar, then lexical- and syntax-phase techniques may be the most effective and efficient to use for inputting, verifying, and representing the data for processing. Front-end techniques can also be applied via software tools to the enforcement of development and programming standards and procedures. Knowledge of compiler techniques and methods helps in the design of new programming languages, new hardware architectures, generation of software applications, and the design of software tools.
