# Domain-specific language | | A **Domain-specific language** (DSL) is a computer language specialized to a particular application domain. This is in contrast to a general-purpose language (GPL), which is broadly applicable across domains. There are a wide variety of DSLs, ranging from widely used languages for common domains, such as HTML for web pages, down to languages used by only one or a few pieces of software, such as MUSH soft code. DSLs can be further subdivided by the kind of language, and include domain-specific markup languages, domain-specific modeling languages, and domain-specific programming languages. Special-purpose computer languages have always existed in the computer age, but the term "domain-specific language" has become more popular due to the rise of domain-specific modeling. Simpler DSLs, particularly ones used by a single application, are sometimes informally called mini-languages. | |-|-| | | wikipedia:: [Domain-specific language](https://en.wikipedia.org/wiki/Domain-specific_language) | [[Puppet]] [[Ansible|Ansible]] [[Jenkins]] pipelines [[GitLab Pipelines]] [[HTML]] [[Regular Expressions|RegEx]]
