My name is Genadi and for the last 2 months, me and Guillermo Iguaran have been working on bringing rails console to the browser under the Google Summer of Code 2013 program. We named the project Web Console and as of this week, we consider the project stable and have released 1.0.0.
The great thing about the project is that it sneaks in a full-featured terminal emulator in the browser, so features like colors, auto completion, auto indentation work out of the box. That means that you can even run Pry and have its advanced features available. Running less or Vim inside of it is not a problem.
Because of the terminal emulator running most of the terminal applications just fine, we provide you a way to actually other commands than
rails console. For example, if you are running a Unix flavor, you can run
login to authenticate a user and spawn a login shell for it. I call that a poor man’s solution to SSH servers ;]
You can check out the project on GitHub for a bit more documentation on what the project can do and how (if you want to) to configure it to your likings.
