Transformation language

A transformation language is a computer language designed to transform some input text in a certain formal language into a modified output text that meets some specific goal^{[clarification needed]}.

Program transformation systems such as Stratego/XT, TXL, Tom, DMS, and ASF+SDF all have transformation languages as a major component. The transformation languages for these systems are driven by declarative descriptions of the structure of the input text (typically a grammar), allowing them to be applied to wide variety of formal languages and documents.

Macro languages are a kind of transformation languages to transform a meta language into specific higher programming language like Java, C++, Fortran or into lower-level Assembly language.

In the model-driven engineering technical space, there are model transformation languages (MTLs), that take as input models conforming to a given metamodel and produce as output models conforming to a different metamodel. An example of such a language is the QVT OMG standard.

There are also low-level languages such as the Lx family^[1] implemented by the bootstrapping method. The L0 language may be considered as assembler for transformation languages. There is also a high-level graphical language built on upon Lx called MOLA.^[2]

There are a number of XML transformation languages. These include Tritium, XSLT, XQuery, STX, FXT, XDuce, CDuce, HaXml, XMLambda, and FleXML.
