NEXT Rails - WIP

next_rails is a gem that will help you upgrade your rails applications to the next rails version.

Usage

The first thing you want to do is setup dual bootin. This will allow you to boot your application with two versions of Rails, the current one and the one you are trying to upgrade to.

Init

$ next init --rails-version 6.0.0

This command will do a a few things:

  1. It will create a Gemfile.next symlink. This Gemfile will be used when you want to run your application with the new Rails version.
  2. It will modify your Gemfile to add magic 🔮 that the next tool will use

Now to execute commands in the context of your new Rails version all you have to do is prepend the next tool to any of your normal commands.

Example:

next install this will try to bundle istall with your new Rails version

next rspec spec/... check if your tests pass with your new Rails version.

$ next --help
Commands:
 next compatibility   # Check if your current "bundle" is compatible with a specific version of Ruby on Rails
 next init            # Configure dual booting
 next outdated        # Check which gems are outdated in your "bundle"
 next help [COMMAND]  # Describe available commands or one specific command
