Emacs plug-in developed for Ruby on Rails

I mainly use two plug-ins: rinari and Yari.

Rinari supports fast jump to multiple files in the rails project. In addition, it provides the grep tool, which I found useful. The shortcut keys are easy to remember.

Yari provides an Emacs interface for the RI tool that comes with Ruby, which is compatible with the latest Ruby and easy to operate. You only need to use the Yari-Anything function. however, the Yari-Anything shortcut key F1 recommended in its official documentation has some remote terminal problems. I changed it to 'C-C; R '.
