A domain-specific language (DSL) is a programming or executable specification language that offers, through appropriate notations and abstractions, expressive power focused on, and usually restricted to, a particular problem domain.
Forms of DSLs
- Configuration tool
- Library in a programming language
- Textual DSL
- Visual DSL
Advantages of DSLs over General-Purpose Languages (GPLs)
- Domain-specific abstractions
- Domain-specific concrete syntax
- Domain-specific error checking
- Domain-specific optimizations
- Domain-specific debugging, version control etc.
