Umple as a Template Language (Umple-TL)

We extend Umple, a model-oriented programming language, to incorporate text emission from templates as an integral feature. Umple as a template language (Umple-TL) is the term we use to describe the template sublanguage of Umple. Using Umple-TL, developers can benefit from synergies among UML modelling, templating and programming in several target languages (Java, C++), all in one textual language - Umple. Umple itself is written in Umple; using Umple-TL, we eliminated Umple's dependency on third-party libraries for text emission. We also support any other application developed in JET to be converted to use Umple-TL and attain benefits such as smaller and faster executables, target-language independence and IDE independence. The word 'template' in this paper refers to patterns for the generation of output, and not to generic types, another common use of the term.
