# Screenshots

This gem takes a list of URLs, gets the title of each page at those URLs, then builds an HTML string that can be copied-pasted in a blog article to present those web pages.
It assumes screenshots of those pages would have been uploaded on the blog.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'screenshots'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install screenshots

## Configuration

```ruby
# config/initializers/screenshots.rb
Screenshots.configure do |config|
  config.blog_assets_url = 'http://www.codeur.com/blog/wp-content/uploads/2014/07'
  config.image_extension = 'jpg'
end
```

## Usage

### Directly call the binary

    $ screenshots my-input-file.txt my_output_dir

### Generate HTML for a single URL

```ruby
Screenshots::Processor.generate('http://www.google.com')
```

It returns a string containing the HTML code to be copied in the blog post:
```html
<h2><a href="http://www.google.com">Google</a></h2>
<img src="http://www.codeur.com/blog/wp-content/uploads/2014/07/http_www.google.com.jpg" />
```

### Generate HTML for a list of URLs

```ruby
Screenshots::Processor.generate_list(['http://www.google.com', 'http://www.lemonde.fr'])
```
