    Arcimboldo

    Arcimboldo

    Generator's generator (JSON templates plus automatic DSL generation)

    Generating the files of an application with the help of a DSL (domain specific language) is very nice . . . provided the development of the DSL itself is not more complex than the application development itself. This workbench is based on the JSON templates and a so-called description file that lists the files to generate. It requires thus a minimum of knowledge and effort to manage the templates and the source specification. It provides a powerful multi-file editor that highlights the cross-references between the templates, the JSON object, the description list and the resulting files. For example, a simple click in an application file allows a developer to see where the clicked symbol does come from. The workbench can be used as a JSON based generator, but a DSL based on Xtext and Xtend can be generated from the JSON object with a single click. The tool can be used to support model driven development.

    Auto

    Auto

    A collection of source code generators for Java

    Auto is a collection of source code generators for Java. Java is full of code that is mechanical, repetitive, typically untested and sometimes the source of subtle bugs. Sounds like a job for robots! The Auto subprojects are a collection of code generators that automate those types of tasks. They create the code you would have written, but without the bugs. Save time. Save code. Save sanity. Some of Auto subprojects are AutoFactory, JSR-330-compatible factories, AutoService, provider-configuration files for ServiceLoader, AutoValue, immutable value-type code generation for Java 7+, and Common, helper utilities for writing annotation processors. Auto is licensed under the Apache License, Version 2.0.
