Rails core - Jan 2010 - Overriding the default rails app generator - how?

Hi,

I have been working a lot on getting a grasp of creating rails 3
generators.
I have created some nifty generators and some Mongo Mapper and Mongo
generators.

Now I am considering creating a complete Rails app generator, to
customize it to my needs.
It seems a bit akward to use the "current" approach where you simply
add on some steps at the end of the generation to remove certain files
and add some extras etc.

Does anyone have any idea for how to do this?
I think what is required is to simply create a Thor task and
installing it on the system, but how can I make this thor task call a
generator in an installed gem? Hmm.. I guess I could just require the
gem in the Thor task?

Thanks!

You could have the gem install the thor task for you. That way you
only get the task if the gem is available.

Sounds great! How would I do that exactly?

Thor, as it exists today, has two components:

    * The Thor superclass, which works exactly like CLI/Hermes, except
that you inherit from it instead of including it (class MyApp < Thor).
    * The Thor runner, which can run Thortasks that are in a local
directory or installed from a remote location

The thor runner allows you to make files like:

# module: random

class Amazing < Thor
  desc "describe NAME", "say that someone is amazing"
  method_options :forcefully => :boolean
  def describe(name, opts)
    ret = "#{name} is amazing"
    puts opts["forcefully"] ? ret.upcase : ret
  end

  desc "hello", "say hello"
  def hello
    puts "Hello"
  end
end


You can also install local tasks or remote tasks to your system thor
cache and make them available anywhere:

$ thor install task.thor

Not sure how to integrate this with a generator gem...

Fx this gem:
