Question

Helo, I want to pass a block of html/text, could include links, into a method. The method needs to break words with more than 10 characters. Here’s what I have so far:

def magic_format(str, len = 10)
 fragment = /.{#{len}}/
 str.split(/(\s+)/).map! { |word|
  (/\s/ === word) ? word : word.gsub(fragment, '\0<wbr />')
 }.join


 # AutoLink URLs
 str = auto_link(str, :html => { :target => '_blank' })

end

The gsub doesn’t seem to be working for some reason, it isn’t adding wbr tags.

Thoughts? Thanks

The map and regex part of that works (not sure if it’s the nicest way of doing it, but it works). It’s just not changing str. This should do the trick…

def magic_format(str, len = 10)
  fragment = /.{#{len}}/
  str = str.split(/(\s+)/).map! { |word|
    (/\s/ === word) ? word : word.gsub(fragment, '\0<wbr />')
  }.join

  auto_link(str, :html => { :target => '_blank' })
end
