Domain-Specific Language is a programming language intended for a particular application domain

A domain-specific language (DSL) is a programming language intended for a particular application domain.

Well-known examples that can be considered DSLs include for markup, for statistics.

There are three key points in above mentioned definition.

  1. Programming Language: DSL is a programming language, which is used by humans to instruct a computer to do something.
  2. Limited Expressiveness: DSL is not a general purpose language like C, Java, etc. It supports minimum features needed to support its domain. Programmer cannot build entire software system using DSL.
  3. Domain focus: DSL focuses on a small domain. The limited focus makes it easy to understand and easy to use.

Martin Fowler divides DSL mainly into two categories :

  1. A External DSL : it is a standalone language with its own custom syntax, but adopting other language such as XML syntax is common. Example of external DSLs are for database queries, languages.
  2. An Internal DSL : They are intrinsically embedded inside a general-purpose language, such as Lava (hardware description language on top of ), (build system on top of ), or (structured markup language on top of ).
