Abstract

) Roberto Ierusalimschy y Luiz Henrique de Figueiredo z Abstract Lua is a language specifically designed to be tailored for specific domains. In this sense, Lua can be regarded as a language framework. This paper describes our experience using Lua for building different Domain-Specific Languages. These domains include bibliographic databases, user-interfaces, graphical metafiles, and finite element analysis. 1 Introduction Many domain-specific languages can be classified as description, or configuration, languages. Under this label, we mean languages without strong run-time semantics, in which the output has a strong resemblance---sometimes an isomorphism---with the "program" tree itself. Well known examples of such languages are: ffl the language used by BibT E X to specify bibliographic references [6]; ffl UIL (User Interface Language), used to describe graphical user interfaces in Motif [4]; ffl VRML (Virtual Reality Modeling Language), used to describe three-dimensional o...
