IntelliJ IDEA 2017.3 Help

Rbenv Support

This feature is supported in the Ultimate edition only.

In this section:

Overview

rbenv is intended for *NIX and macOS!

IntelliJ IDEA supports rbenv versions up to the latest.

At startup, IntelliJ IDEA scans your ~/.rbenv folder, and automatically configures SDK's for each Ruby interpreter. The detected interpreters are shown in the Modules page of the Project Structure Dialog dialog.

IntelliJ IDEA also detects newly installed rbenv interpreters "on-the-fly". On reopening the Project Structure dialog, you will find updates in the Gems tab of the Modules page..

Prerequisites

  • rbenv is installed on your computer.
  • Ruby interpreters are installed.
  • IntelliJ IDEA supports rbenv Ruby interpreters installed in the default rbenv folder ~/.rbenv only.
  • rbenv is incompatible with rvm! Any references to rvm should be removed before using rbenv.

Support for rbenv-gemsets plugin

IntelliJ IDEA supports rbenv-gemsets plugin for *NIX and macOS.

  • The gemsets are shown as the children of rbenv SDK. When a gemset is selected, its gems are shown to the right, rbenv SDK with gemsets is selected, then all the gems of this SDK and the gemsets are shown.
  • IntelliJ IDEA provides libraries for gems from the current gemset list ( by '.rbenv-gemsets') including the default 'global' gemset
  • IntelliJ IDEA invokes all commands with the environment of the specified gemsets and selected SDK ( e.g. $ RBENV_GEMSETS="gemset1 gemset2" RBENV_VERSION="1.9.3-p125" #command)

File .rbenv-gemset

IntelliJ IDEA provides code insight for the .rbenv-gemset file:

  • Code highlighting
  • IntelliJ IDEA provides code completion for the current SDK gemsets in the .rbenv-gemsets file.
  • IntelliJ IDEA provides the ability to create a new gemset using the quick fix Create gemset <gemset name>. Just press Alt+Enter on a new name in the .rbenv-gemsets file:
    /help/img/idea/2017.3/rm_rbenv_gemsets_intention.png

etc.

Important note about remote interpreters

If you are configuring a remote interpreter using rbenv version manager, you have to specify ruby executable located under the directory versions, rather than shims.
