Domain-specific languages are custom text or graphical interfaces that allow domain experts to create and modify their own software systems. With a syntax that's clear and familiar to the non-technical user, DSLs are precise enough to generate working software in traditional code with. Written for developers who need to create user-facing DSLs, Domain-Specific Languages Made Easy unlocks clear and practical methods to create DSLs with easy-to-use interfaces. By working through a detailed example of a car rental company, you'll see how creating a custom DSL can get rid of time-consuming and bureaucratic code adjustments, freeing you up to work on features whilst your clients and colleagues write their software themselves!
