DSL and Parser Combinator
Dávid Pollák, Vishal Layka, Andres Sacco · Apress eBooks · 2022
A domain-specific language (DSL) is a special-purpose language designed to express solutions to problems that belong to a particular problem domain. DSLs have an advantage over a general-purpose language such as Scala and Java. Unfortunately, these general-purpose languages have drawbacks. For example, if you want to execute a task on a database, then it is necessary to write a computer program to execute this task using a general-purpose language. However, a DSL could be used to perform several such tasks on a database. And this is why some experts regard SQL as a DSL. The scope of this chapter is to introduce you to the world of DSLs and how they interact with Scala.
