RODF

RODF is a library for writing to ODF output from Ruby. It mainly focuses creating ODS spreadsheets.

As well as writing ODS spreadsheets, this library also can write ODT text documents but it is undocumented and will require knowledge of the ODF spec. It currently does not support ODP Slide shows. Also this is NOT an ODF reading library.

Install

gem install rodf

How do I use it?

RODF works pretty much like Builder, but with ODF-aware constructs. For example:

require 'rodf'

RODF::Spreadsheet.file("my-spreadsheet.ods") do
  table 'My first table from Ruby' do
    row do
      cell 'Hello world!'
    end
  end
end

For access to variables and methods from outer code you can use block parameter:

require 'rodf'

@data = 'Hello world!'

RODF::Spreadsheet.file("my-spreadsheet.ods") do |spreadsheet|
  spreadsheet.table 'My first table from Ruby' do |table|
    table.row do |row|
      row.cell @data
    end
  end
end

Adding many rows or cells at once is supported as well:

require 'rodf'

RODF::Spreadsheet.file("my-spreadsheet.ods") do
  table 'My first table from Ruby' do
    add_rows([
      [1, 'Alice'],
      [2, { value: 'Bob', color: '#ff0000'}],
      [3, 'Carol']
    ])

    row do
      add_cells ['ID', 'Name']
    end
  end
end

Procedural style

The declarative style shown above is just syntatic sugar. A more procedural style can also be used. Like so:

require 'rodf'

ss = RODF::Spreadsheet.new
t = ss.table 'My first table from Ruby'
r = t.row
c = r.cell 'Hello world!'

# two methods to write to file
ss.write_to 'my-spreadsheet.ods'
# or
File.write('my-spreadsheet.ods', ss.bytes) # you can send your data in Rails over HTTP using the bytes method
end

Both styles can be mixed and matched at will:

require 'rodf'

ss = RODF::Spreadsheet.new
ss.table 'My first table from Ruby' do
  row do
    cell 'Hello world!'
  end
end

ss.write_to 'my-spreadsheet.ods'

Styling and formatting is also possible:

require 'rodf'

RODF::Spreadsheet.file("my-spreadsheet.ods") do
  style 'red-cell', family: :cell do
    property :text, 'font-weight' => 'bold', 'color' => '#ff0000'
  end

  table 'Red text table' do
    row do
      cell 'Red', style: 'red-cell'
    end
  end
end

Conditional formatting is also possible:

require 'rodf'

RODF::Spreadsheet.file("my-spreadsheet.ods") do

  office_style 'red-cell', family: :cell do
    property :text, 'font-weight' => 'bold', 'color' => '#ff0000'
  end

  office_style 'green-cell', family: :cell do
    property :text, 'font-weight' => 'bold', 'color' => '#00ff00'
  end

  # conditional formating must be defined as style and the value of
  # apply-style-name must be an office_style
  style 'cond1', family: :cell do
    property :conditional, 'condition' => 'cell-content()<0', 'apply-style-name' => 'red-cell'

    property :conditional, 'condition' => 'cell-content()>0', 'apply-style-name' => 'green-cell'
  end

  table 'Red text table' do
    row do
      cell 'Red force', style: 'red-cell'
    end
    row do
      cell '-4', type: :float, style: 'cond1'
    end
    row do
      cell '0', type: :float, style: 'cond1'
    end
    row do
      cell '5', type: :float, style: 'cond1'
    end
  end
end
