BaSyx / Developer / Contributing

Contributing

For a contribution to Eclipse BaSyx, the Eclipse Contributor Agreement has to be signed.

Eclipse Contributor Agreement

Eclipse BaSyx is using the Eclipse environment for managing code. Due to this, a valid Eclipse Account with a signed Eclipse Contributor Agreement is needed.

Signed-Off

Additionally, your commit message does need to contain a "signed of by" message. This can be added by using the -s parameter when creating the commit. Below an example of a commit message containing both a change id and a signed of by is given:

 Fixes bug: TCP server threads were never closed
* Adds appropriate unit test
Signed-off-by: Frank Schnicke <frank.schnicke@iese.fraunhofer.de>

Developing new Components

There are multiple ways of implementing BaSys 4.0 conforming components.

Extending Existing Interfaces

For each component, there exist interfaces that can be implemented to realize e.g. new backends. These interfaces integrate seamless in the REST-API-Provider. Additionally, the already defined test suites for the different component types can easily be reused.

In consequence, this is the easiest and fastest way of introducing new components.

Conforming to the REST-API

If the interfaces provided by BaSyx can't be used (e.g. because the component is implemented in a programming language currently not supported by BaSyx), it has to be ensured that the component is conforming to the defined REST-API and behavior.

For this, BaSyx provides a Technology Compatibility Kit (TCK). The TCKs for the components can be found in the repository in components/tck. For each component, there exists a TCK. Each TCK allows to generate a jar file that tests component functionality of arbitrary http endpoints. Each jar can be called in the following way:

java -jar $JAR $HTTP_ENDPOINT

where $JAR is the name of the component's TCK jar and $HTTP_ENDPOINT is the endpoint on which the component's REST API is available.

Code Formatting

For the Java parts of Eclipse BaSyx, an Eclipse IDE Code Formatter profile is available: File:BaSyx Formatting.zip.
