Zeus engine setup.

custom_plan.rb

require 'zeus/rails'

ROOT_PATH = File.expand_path(Dir.pwd)
ENV_PATH  = File.expand_path('spec/dummy/config/environment',  ROOT_PATH)
BOOT_PATH = File.expand_path('spec/dummy/config/boot',  ROOT_PATH)
APP_PATH  = File.expand_path('spec/dummy/config/application',  ROOT_PATH)
ENGINE_ROOT = File.expand_path(Dir.pwd)
ENGINE_PATH = File.expand_path('lib/my_engine/engine', ENGINE_ROOT)

class CustomPlan < Zeus::Rails
end

Zeus.plan = CustomPlan.new

zeus.json

{
  "command": "ruby -rubygems -r./custom_plan -eZeus.go",

  "plan": {
    "boot": {
      "default_bundle": {
        "development_environment": {
          "prerake": {"rake": []},
          "runner": ["r"],
          "console": ["c"],
          "server": ["s"],
          "generate": ["g"],
          "destroy": ["d"],
          "dbconsole": []
        },
        "test_environment": {
          "test_helper": {"test": ["rspec", "testrb"]}
        }
      }
    }
  }
}

It works, just a little note.

If you see your tests running twice, one pass and another fail in case of passing spec, then you should remove

require 'rspec/autorun'

from your rspec_helper.rb file.

And at line 8 from custom_plan.rb https://gist.github.com/Tobscher/4674086#file-custom_plan-rb-L8 , do rename my_engine with your engine name as well.

Works for test and generate, but oddly enough, not for destroy:

jaiken@firefly➜ git:(master) git st
# On branch master
nothing to commit, working directory clean
jaiken@firefly➜ git:(master) zeus generate model Foo
      invoke  active_record
      create    db/migrate/20131030000225_create_foos.rb
      create    app/models/foo.rb
      invoke    rspec
      create      spec/models/foo_spec.rb
      invoke      factory_girl
      create        spec/factories/foos.rb
jaiken@firefly➜ git:(master) ✗ zeus destroy model Foo
      invoke  active_record
      remove    migration.rb
      remove    app/models/foo.rb
      invoke    rspec
      remove      spec/models/foo_spec.rb
      invoke      factory_girl
      remove        spec/factories/foos.rb
jaiken@firefly➜ git:(master) ✗ git st
# On branch master
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   app/models/foo.rb
#   db/migrate/20131030000225_create_foos.rb
#   spec/factories/foos.rb
#   spec/models/foo_spec.rb

Still, got me alot zeusy than I was before, thanks! :)
