JetBrains’ IntelliJ has long been the gold standard for Java IDEs. Now the company is taking a shot at turning their suite into a good fit for Ruby and Rails development. This new love is coming in the form of a new official Ruby plug-in.
It features assisted Ruby coding, with keyword completion, syntax highlighting, on-the-fly code validation, error highlighting, and Rails templates and generator integration. They even put together a screencast to show it off.
Cool stuff. Especially if you already plugged down $400 for a license or work on an open-source project (free license, then).
