Software production with factory components Reuse of off-the-shelf factory components Development by assembly Adaptation to a specific context

EGF is an engine based on four types of generation unit:

• Task: it enables to execute code written in a language (e.g., Java, Ant, JRuby) or tools (e.g., Acceleo, ATL, Jet)
• Factory component: it declares generation parameters and orchestrates calls to tasks or other factory components
• Pattern: it is a powerful formalism which enables to process resources (e.g., model, file), in a language (e.g., Java, Jet), with parameters (e.g., navigation strategy, post-processor, reporter)
• Generation Chain: it is a domain-specific model which enables to abstract generations

EGF is designed to be extensible and accept new types of generation unit. On the other hand, because a task is able to execute code and tools, EGF is not strictly limited to generation.

Software Factories Portfolios

A software factory portfolio provides an off-the-shelf generation solution. EGF is released with two portfolios:

• Enhanced EMF Generation: 1) it enriches the EMF generation with new generation topics (e.g., html doc, ecoretools diagrams, Java doc), 2) it opens the EMF Generation customization with the EGF patterns
• Build chain editor and generator: it provides 1) an editor to model a build chain for continuous integration, and 2) a generator with targets, by default, Hudson/jenkins and Buckminster
