page as block?

[runs_with_kona]

Is there a way to do something like,

page1 = new_page(options) {|page|
content...
}


If some_condition
pdf.render page1
else
pdf.render page2
end

[Gregory Brown]

Sure.

page1 = lambda { |pdf|
# ...
}

if some_condition
page1[pdf]
else
#...
end

You can also use ordinary methods for this.

A pattern I like to use is:

class MyDocument < Prawn::Document

# whatever helpers

end

MyDocument.generate("foo.pdf") { |pdf| ... }
