### Basic Objects and Basic Usage

```ruby
require 'thinreports'

report = Thinreports::Report.new layout: 'report.tlf'

report.start_new_page do
  item(:title).value('Thinreports')
end

report.start_new_page do |page|
  # Item Finder
  page.item(:item_id) # => Item object
  page[:item_id]      # => Item object

  # Text block
  page.item(:text_block).value('Pure Ruby')
  page.item(:text_block).value = 'Pure Ruby'
  page[:text_block] = 'Pure Ruby'
  page.item('text_block').set('value', color: '#0000ff')
  page.item(:text_block).format_enabled(false)

  # Image block
  page.item(:image_block).src('/path/to/image.png')
  page.item(:image_block).src = '/path/to/image.png'
  page[:image_block] = '/path/to/image.png'
  require 'open-uri'
  page.item(:image_block).src(open('http://www.thinreports.org/assets/logos/thinreports-logo.png'))

  # Attributes
  page.item(:any).hide
  page.item(:any).show
  page.item(:any).visible(true)
  page.item(:any).visible? # => true
  page.item(:any).id # => "any"

  # Styles
  page.item(:text).style(:color, 'red')
  page.item(:text).style(:bold, true)
  page.item(:text).style(:italic, true)
  page.item(:text).style(:linethrough, true)
  page.item(:text).style(:underline, true)
  page.item(:text).style(:font_size, 20)

  page.item(:text).style(:align, :left or :center or :right)
  page.item(:text).style(:valign, :top or :center or :bottom)

  page.item(:rectangle).style(:border_color, '#ff0000')
                       .style(:border_width, 1)
                       .style(:fill_color, '#ffffff')

  # Bulk setting of styles
  page.item(:text).styles(color: '#00000', align: :right)

  # Bulk setting of values
  page.values text_block_a: 'value', text_block_b: 'value'

  # Helpers
  page.item_exists?(:existing_id)  # => true
  page.item_exists?('existing_id') # => true
  page.item_exists?(:unknown_id)   # => false
end

report.generate(filename: 'report.pdf')
```

```ruby
Thinreports::Report.generate(filename: 'report.pdf', layout: 'report.tlf') do |report|
  report.start_new_page do |page|
    # :
  end
end
```

### Report and Page

```ruby
report = Thinreports::Report.new layout: 'foo.tlf'

3.times { report.start_new_page }

# Returns all pages
report.pages # => [<Report::Page>, <Report::Page>, <Report::Page>]
# Returns number of pages
report.page_count # => 3

# Add a blank page
report.add_blank_page

report.pages.last # => Report::BlankPage
```

### Using multiple layouts

```ruby
report = Thinreports::Report.new

report.use_layout '/path/to/default.tlf', default: true
report.use_layout '/path/to/other1.tlf', id: :other

report.start_new_page do |page|
  # use '/path/to/default.tlf' layout
end

report.start_new_page layout: :other do |page|
  # use '/path/to/other1.tlf' layout
end

report.start_new_page layout: '/path/to/other2.tlf' do |page|
  # use '/path/to/other2.tlf' layout
end
```

### Callbacks

```ruby
report = Thinreports::Report.new layout: 'foo.tlf'

# It will be called before finalizing each page
report.on_page_create do |page|
  page.item(:text).value('Text for all pages')
end
```

end

10.times do |n|
  report.list.add_row do |row|
    row.item(:text_block).value(n)
  end
end

report.generate(filename: 'list.pdf')
```

```ruby
report = Thinreports::Report.new layout: 'list_with_footer.tlf'

report.list do |list|
  total_price = 0
  price_per_page = 0

  list.on_page_finalize do
    total_price += price_per_page
    price_per_page = 0
  end

  list.on_page_footer_insert do |footer|
    footer.values price: price_per_page
  end

  list.on_footer_insert do |footer|
    footer.item(:price).value(total_price)
  end

  [100, 200, 300].each do |price|
    list.add_row do |row|
      row[:price] = price
    end
    price_per_page += price
  end
end
```

### How to run feature tests

```
$ bundle exec rake test:features
```

In order to run `test:features`, you need to install [diff-pdf](https://github.com/vslavik/diff-pdf) in your environment, or you can run test in the docker container as below.

### How to develop in Docker container

You can use the Docker container for development. This container contains the libraries required for testing, such as diff-pdf.

```
$ docker build -t thinreports-dev .
$ docker run -v $PWD:/thinreports:cached -it thinreports-dev bash

> /thinreports#
```

You can run test:

```
> /thinreports# bundle install
> /thinreports# bundle exec rake test:features
```

1. Update the version number in `version.rb`
2. Update `CHANGELOG.md` and `README.md` (if needed)
3. Create the Release PR like #105
4. Merge the PR
5. Is the master CI green? If not, make it green
