## Why this exists



When I was creating my first major Sinatra project, [Cook This Way](https://github.com/thebrianemory/cook-this-way), while doing [Learn Verified](https://learn.co/with/thebrianemory), I was looking for a way to build a Sinatra skeleton similar to running



    rails new APP-NAME



[Hazel](https://github.com/c7/hazel) was the closest thing I could find and this gem is based largely off of it. While it did provide a pretty good initial setup, I still had to tweak some things. The views were sitting in the root directory while I wanted them to reside in an app folder along with my models and controllers. There was also no environment.rb in the config folder as I had become accustom to having.



I also wanted to create a gem for future Learn students so they could easily get started building their projects. Although built with them in mind, this can get you off and running with any Sinatra app.



Install the gem, run `corneal new APP-NAME`, run `bundle install`, and you're all set! You can start up your server with `shotgun` and verify everything is working. It is as simple as that.



It uses a file structure similar to what you would see with Rails.



Directory structure:

```

├── config.ru

├── Gemfile

├── Gemfile.lock

├── Rakefile

├── README

├── app

│   ├── controllers

│   │   └── application_controller.rb

│   ├── models

│   └── views

│       ├── layout.erb

│       └── welcome.erb

├── config

│   ├── initializers

│   └── environment.rb

├── db

│   └── migrate

├── lib

│   └── .gitkeep

└── public

    └── spec_helper.rb

```



## Installation



    gem install corneal



## Commands

```

corneal -v              # Show Corneal version number

corneal help [COMMAND]  # Describe available commands or one specific command

corneal new APP-NAME    # Creates a new Sinatra application

corneal model NAME      # Generate a model

corneal controller NAME # Generate a controller

corneal scaffold NAME   # Generate a model with its associated views and controllers

```

The controller generator also have an optional views flag `--no-views` to create controllers without views.



## Using Corneal



To generate your app:



    corneal new APP-NAME



After Corneal is done generating your app, run `bundle install` from your app's directory:



    cd APP-NAME

    bundle install



You can then start your server with `shotgun`:



    shotgun



You can generate a model and migration file:



    corneal model NAME



You can also generate an entire MVC structure complete with a migration file:



    corneal scaffold NAME



The resulting structure will look like this:



```

└─app

  ├── controllers

  │   ├──application_controller.rb

  │   └──new_model_controller.rb

  ├── models

  │   └──new_model.rb

  └── views

      ├──new_models

      │  ├──index.html.rb.erb

      │  ├──show.html.rb.erb

      │  ├──new.html.rb.erb

      │  └──edit.html.rb.erb

      ├── layout.erb

      └── welcome.erb

```



You can also add your model attributes when you generate the scaffold structure and have them added to your migration file:



    corneal [model/scaffold] NAME name:string age:integer



```

class CreateUsers < ActiveRecord::Migration

  def change

    create_table :users do |t|

      t.string :name

      t.age :integer



      t.timestamps null: false

    end

  end

end

```



Visit [http://localhost:9393/](http://localhost:9393/) to verify your app is running.



You can also verify it is working by running `rspec` to see the passing test:



    1 example, 0 failures
