This plugin integrates the Droplet Editor into an IntelliJ IDEA Plugin. The Droplet Editor is also used in Pencil Code (http://pencilcode.net/) and some code.org exercises. Eventually, we hope to support all languages supported by Droplet and the various tools in the JetBrains IDE family.
Amphibian can be installed like any other IntelliJ plugin through the plugin menu. It is also available on the JetBrains Plugin Repository (https://plugins.jetbrains.com/plugin/15716-amphibian-editor).
Amphibian uses a custom variant of the Droplet Editor from Pencil Code (http://pencilcode.net).
