how to break line in ruby on rails after X characters?

I am using this code to display the headline if there is one

<%= @user.headline if @user.headline? %>

I have it limited to 100 characters. How can I break this headline after 50 characters and display the broken part below? I am planning to have them centered in two lines.

For example:

If this is the headline which goes over 100 characters then I want to display it like this

Display:

If this is the headline which goes over 100 characters then

I want to display it like this

You can break string as follows:

head_line = @user.headline.scan(/.{1,50}/)

In your case you can use word_wrap:

word_wrap(@user.headline, :line_width => 50)

You could use word_wrap from text helper:

include ActionView::Helpers::TextHelper
# or in a controller
# helper :text

word_wrap(@user.headline, :line_width => 50)

The word_wrap method was made specifically to address this.

However, it inserts newlines instead of what you'd need for breaking lines in HTML (such as encasing different lines in their own <p> tags). I'd implement that functionality as a helper method after taking a good look at how the TextHelper's word_wrap method is implemented.
