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.
gem install rodf
RODF works pretty much like Builder, but with ODF-aware constructs. For example:
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:
@data = 'Hello world!'
RODF::Spreadsheet.file("my-spreadsheet.ods") do |sheet|
sheet.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:
RODF::Spreadsheet.file("my-spreadsheet.ods") do |sheet|
sheet.table 'My first table from Ruby' do |t|
t.add_rows([
[1, 'Alice'],
[2, { value: 'Bob', color: '#ff0000'}],
[3, 'Carol']
])
t.row do |r|
r.add_cells ['ID', 'Name']
end
end
end
The declarative style shown above is just syntatic sugar. A more procedural style can also be used. Like so:
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
Both styles can be mixed and matched at will:
ss = RODF::Spreadsheet.new
ss.table 'My first table from Ruby' do |t|
t.row do |r|
r.cell 'Hello world!'
end
end
ss.write_to 'my-spreadsheet.ods'
RODF::Spreadsheet.file("my-spreadsheet.ods") do |sheet|
sheet.style 'red-cell', family: :cell do |s|
s.property :text, 'font-weight' => 'bold', 'color' => '#ff0000'
end
sheet.style 'row-height', family: :row do |s|
s.property :row, 'row-height' => '18pt', 'use-optimal-row-height' => 'true'
end
sheet.table 'Red text table' do |t|
t.row style: 'row-height' do |r|
r.cell 'Red', style: 'red-cell'
end
end
sheet.table 'Text with Paragraphs' do |t|
t.row style: 'row-height' do |r|
r.cell do |cell|
cell.paragraph do |paragraph|
text_array = my_text_content.split("\n").select{|x| !x.empty? }
text_array.each do |str|
if str.start_with?("#")
paragraph.span(str, style: 'red-cell')
else
paragraph.span(str)
end
end
end
end
end
end
end
Conditional formatting is also possible:
RODF::Spreadsheet.file("my-spreadsheet.ods") do |sheet|
sheet.office_style 'red-cell', family: :cell do |s|
s.property :text, 'font-weight' => 'bold', 'color' => '#ff0000'
end
sheet.office_style 'green-cell', family: :cell do |s|
s.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
sheet.style 'cond1', family: :cell do |s|
s.property :conditional, 'condition' => 'cell-content()<0', 'apply-style-name' => 'red-cell'
s.property :conditional, 'condition' => 'cell-content()>0', 'apply-style-name' => 'green-cell'
end
sheet.table 'Red text table' do |t|
t.row do |r|
r.cell 'Red force', style: 'red-cell'
end
t.row do |r|
r.cell '-4', type: :float, style: 'cond1'
end
t.row do |r|
r.cell '0', type: :float, style: 'cond1'
end
t.row do |r|
r.cell '5', type: :float, style: 'cond1'
end
end
end
Adding columns or columns width to your spreadsheet can be done with the following
RODF::Spreadsheet.file("my-spreadsheet.ods") do |sheet|
sheet.table "foo" do |t|
sheet.style('default-col-width', family: :column) do |s|
s.property(:column, 'column-width' => '1.234in')
end
col_count.times do
t.column style: 'default-col-width'
end
### OR
### Warning this will overwrite any existing table columns (cells remain unaffected)
sheet.set_column_widths(
table: t,
column_widths: [
{'column-width' => '1in'},
{'column-width' => '2cm'},
{'column-width' => '2.54cm'},
],
)
end
end
Available columns types are:
- :string
- :float
- :date
- :time
- :currency
- :percentage
### family: :cell or "table-cell"
style "my-cell-style", family: :cell do
property :text,
'font-weight' => :bold, #options are :bold, :thin
'font-size' => 12,
'font-name' => 'Arial',
'font-style' => 'italic',
'text-underline-style' => 'solid', # solid, dashed, dotted, double
'text-underline-type' => 'single',
'text-line-through-style' => 'solid',
align: true,
color: "#000000"
property :cell,
'background-color' => "#DDDDDD",
'wrap-option' => 'wrap',
'vertical_align' => 'automatic',
'border-top' => '0.75pt solid #999999',
'border-bottom' => '0.75pt solid #999999',
'border-left' => '0.75pt solid #999999',
'border-right' => '0.75pt solid #999999',
'writing-mode' => 'lr-tb',
end
### family: :column or "table-column"
style('my-col-style', family: :column) do
property :column,
'column-width' => '4.0cm'
end
### family: :row or "table-row"
style('my-row-style', family: :row) do
property :row,
'row-height' => '18pt',
'use-optimal-row-height' => 'true'
end
### family: :table
style('my-row-style', family: :table) do
property :table,
'writing-mode' => 'lr-tb',
RODF::Spreadsheet.file("my-spreadsheet.ods") do |sheet|
sheet.table 'My first table from Ruby', attributes: {'table-protected' => 'true'} do |table|
table.row do |row|
row.cell @data
end
end
