πŸ’Ώ Plugin installation

You can install the plugin via the Eclipse Marketplace, or simply drag the following button to your running Eclipse window:

Drag to your running Eclipse* workspace. *Requires Eclipse Marketplace Client

Alternatively, head to the update site and follow the instructions listed there.

Once installed, the plugin will simply kick in when opening any Ruby file in Eclipse; there is no Ruby-specific project type or perspective.

πŸ“… Compatibility

This plugin requires Java 11 or more recent.

The aim is to provide support for all Eclipse releases that are at up to two years old. Versions older than that may be dropped at any point without notice. That being said, the plugin should currently still work with Eclipse versions as old as 2019-03 (4.11).

✨ Tips and tricks

  • You can fine-tune Solargraph's behaviour by creating a .solargraph.yml configuration file.
  • Similarly, you can fine-tune the code formatting and compiler warnings with a .rubocop.yml file.
  • To improve code completion and intellisense, it is recommended to generate YARD documentation for your gems (run yard gems in a terminal).
  • For web development on ERB files, it is recommended to also install the Wild Web Developer plugin.
