Editing Domain-specific language (section)

===In design and implementation===
Domain-specific languages are languages (or often, declared syntaxes or grammars) with very specific goals in design and implementation. A domain-specific language can be one of a visual diagramming language, such as those created by the [[Generic Eclipse Modeling System]], programmatic abstractions, such as the [[Eclipse Modeling Framework]], or textual languages. For instance, the command line utility [[grep]] has a [[regular expression]] syntax which matches patterns in lines of text. The [[sed]] utility defines a syntax for matching and replacing regular expressions.  Often, these tiny languages can be used together inside a [[operating system shell|shell]] to perform more complex programming tasks.

The line between domain-specific languages and [[scripting language]]s is somewhat blurred, but domain-specific languages often lack low-level functions for filesystem access, interprocess control, and other functions that characterize full-featured programming languages, scripting or otherwise. Many domain-specific languages do not compile to [[byte-code]] or executable code, but to various kinds of media objects: GraphViz exports to [[PostScript]], [[GIF]], [[JPEG]], etc., where [[Csound]] compiles to audio files, and a ray-tracing domain-specific language like [[POV-Ray|POV]] compiles to graphics files.
