Overview

Wraps the text so as the it fits on the page(:area_x). Wrapping happens at whitespace characters without hyphenation. Additionally you can make use of predefined tag and the special tag <br/> to break row. You can disable the parse with second parameter tag_parse=false.

Examples

doc=Document.new
doc.define_tags do
  tag :font1, :name => 'Helvetica', :size => 10, :color => '#F34811' 
  tag :font2, :name => 'Times',     :size => 11, :color => '#A4297A' 
  tag :font3, :name => 'TimesBold', :size => 12, :color => '#AA3903' 
end
my_text="<font1>foo, bar, baz</font1>,<font2>qux, quux</font2>, corge, grault, garply, waldo, <font3>fred, plugh,</font3> xyzzy,<br/> thud, bing" 
doc.text my_text

Without parse

text="<font1>foo, bar, baz</font1>,<font2>qux, quux</font2>, corge, grault, garply, waldo, <font3>fred, plugh,</font3> xyzzy,<br/> thud, bing" 
doc.text text,false
