Handly Contributor Guide ======================== Welcome to Handly, a technology project at Eclipse, and thanks for your interest in this project. Project description ------------------- Handly provides basic building blocks for handle-based models, with an emphasis on high-level code-centric models that render Eclipse workspace from a programming language angle. It allows creating highly scalable, robust, and thoroughly optimized models similar in quality to the tried-and-tested Java model of Eclipse Java development tools while reducing programming effort, fostering software reuse, and enabling interoperability. Handly is designed for flexibility and can be used to create source code models for practically any language, whether general-purpose or domain-specific; it is compatible with any parsing technology. The model implementor has complete control over the model's base-level API, including the ability to implement a preexisting handle-based model API. At the same time, the provided uniform meta-level API establishes a common language and makes it possible for IDE components to work in a generic way with any Handly-based model.

Make sure you have JDK 8 and Maven 3 installed. Both should be on the path. 2. Clone the Handly Git repository and pick the desired branch. 3. Open a shell to the Git workspace and execute $ cd releng $ mvn clean install Once the build completes, the `repository/target` folder in the Git workspace will contain a repository of build artifacts. Setting up a developer workspace -------------------------------- Handly currently uses `JavaSE-1.8` for compilation. Please add a matching JRE. Perfect match (i.e. JDK 1.8) is recommended to avoid build warnings. Handly employs specific Java code formatting conventions. Please import and use the formatter profile from `tools/formatter.xml`. Note that the current profile is intended to be used with the new formatter available since the Eclipse Mars (4.5) release, and may produce suboptimal results if used with previous Eclipse versions. Import all projects from the Git workspace (don't search for nested projects) and set the target platform using a `.target` file provided within the `targets` project. There are currently two target platforms defined. The base platform (`base.target`) defines the base API level, whereas the latest platform (`latest.target`) defines the latest functional level. Development tends to be done against the base platform, while continuous integration tends to be done against the latest platform. Handly Examples define some auxiliary Xtext-based languages. Note that for the MWE2 generator of the language infrastructure to work correctly, the Eclipse installation and the target platform should contain the same version of Xtext. A simple way to ensure that is to install Eclipse using one of the provided `.p2f` files that can be found in the Git workspace `tools` folder. These `.p2f` files are kept consistent with their namesake `.target` files.
