# DRG

A Ruby utility to help automate common tasks! Currently includes stuff like enhanced dependency management using Bundler and RSpec scaffolding.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'drg'
```

## Tasks

```bash
rake drg:update
rake drg:pin
rake drg:pin:minor
rake drg:pin:major
rake drg:unpin
```

### drg:update

DRG can update your outdated gems, one-by-one, to the latest version. It'll update the gem and then run your tests.
If your tests pass, then the new version will be written to your Gemfile (similar to Gemnasium).

```bash
rake drg:update
```

### pin

DRG really wants to help you manage your project's gems. But DRG doesn't want to replace Bundler. Instead we want to build on
it. Pinning ignores gems that are fetched from somewhere other than rubygems. For example, gems listed with `:git`, `:github`,
or `:path` will be ignored. You can "pin" all your versions to the current version listed in the Gemfile.lock:

```bash
rake drg:pin
```

Which will change gems list in your Gemfile to their full version. So if you have a gemfile that looks like:

```ruby
gem 'rails'
gem 'byebug', require: false
gem 'therubyracer', '~> 0.12', platforms: :ruby
gem 'drg'
```

it'll get changed to

```ruby
gem 'rails', '4.2.3'
gem 'byebug', '5.0.0', require: false
gem 'therubyracer', '0.12.2', platforms: :ruby
gem 'drg', '0.4.1'
```

### pin:minor

Although, you may want to pin gems with their _minor_ version (which allows updating patches). Run:

```bash
rake drg:pin:minor
```

Which will update your Gemfile from

```ruby
gem 'rails', '4.2.3'
```

to 

```ruby
gem 'rails', '~> 4.2'
```

This can be combined with `bundle update` to quickly update all gems to the latest patch or minor level.

### pin:major

There is also a

 ```bash
 rake drg:pin:major
 ```

### drg:unpin

Remove the versions from your Gemfile. Start fresh!

```bash
rake drg:unpin
```

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake` to run the tests. 
You can also run `bin/console` for an interactive prompt that will allow you to experiment.
