Tool Support For Domain-specific Language Languages
Many General-Purpose Modeling languages already have tool support available in the form of CASE tools. Domain-specific language languages tend to have too small a market size to support the construction of a bespoke CASE tool from scratch. Instead, most tool support for domain-specific language languages is built based on existing domain-specific language frameworks or through domain-specific language environments.
A domain-specific language environment may be thought of as a metamodeling tool, i.e., a modeling tool used to define a modeling tool or CASE tool. The resulting tool may either work within the domain-specific language environment, or less commonly be produced as a separate stand-alone program. In the more common case, the domain-specific language environment supports an additional layer of abstraction when compared to a traditional CASE tool.
Using a domain-specific language environment can significantly lower the cost of obtaining tool support for a domain-specific language language, since a well-designed domain-specific language environment will automate the creation of program parts that are costly to build from scratch, such as domain-specific editors, browsers and components. The domain expert only needs to specify the domain specific constructs and rules, and the domain-specific language environment provides a modeling tool tailored for the target domain.
Most existing domain-specific language takes place with domain-specific language environments, either commercial such as MetaEdit+ or Actifsource, open source such as GEMS, or academic such as GME. The increasing popularity of domain-specific language has led to domain-specific language frameworks being added to existing IDEs, e.g. Eclipse Modeling Project (EMP) with EMF and GMF, or in Microsoft's DSL Tools for Software Factories.

Famous quotes containing the words tool, support, language and/or languages:
“A broken altar, Lord, thy servant rears,
Made of a heart, and cemented with tears:
Whose parts are as thy hand did frame;
No workman’s tool hath touched the same.”
—George Herbert (1593–1633)
“Because the young child feels with such intensity, he experiences sorrows that seem inconsolable and losses that feel unbearable. A precious toy gets broken or a good-bye cannot be endured. When this happens, words like “sad” or “disappointed” seem a travesty because they cannot possibly capture the enormity of the child’s loss. He needs a loving adult presence to support him in his pain but he does not want to be talked out of it.”
—Alicia F. Lieberman (20th century)
“The hypothesis I wish to advance is that ... the language of morality is in ... grave disorder.... What we possess, if this is true, are the fragments of a conceptual scheme, parts of which now lack those contexts from which their significance derived. We possess indeed simulacra of morality, we continue to use many of the key expressions. But we have—very largely if not entirely—lost our comprehension, both theoretical and practical, of morality.”
—Alasdair Chalmers MacIntyre (b. 1929)
“It is time for dead languages to be quiet.”
—Natalie Clifford Barney (1876–1972)
