Contributor's guide

Prerequisites

We recommend using IntelliJ for developing ingraph. Make sure you install the Scala plug-in.

Importing the projects

  • Import the projects using New | Project from Existing Sources... (or simply click Import Project on the welcome screen).
    • Select the ingraph directory.
    • Tick Auto import.
    • Untick Create separate module per source set. Until this IntelliJ issue is resolved, tick Create separate module per source set.
    • Pick Use default gradle wrapper as your Gradle installation.
  • After importing, add the Scala SDK (version 2.11) to the module. (If you did not use Scala before, download it from the dialog box provided by IntelliJ).

Third-party dependencies

For parsing queries, we use the Slizaa openCypher Xtext grammar.
