highlight

Highlights one or more phrases everywhere in text by inserting it into a :highlighter string. The highlighter can be specialized by passing :highlighter as a single-quoted string with 1 where the phrase is to be inserted (defaults to ‘<strong class=“highlight”>1’)

Examples

highlight('You searched for: rails', 'rails')
# => You searched for: <strong class="highlight">rails</strong>

highlight('You searched for: ruby, rails, dhh', 'actionpack')
# => You searched for: ruby, rails, dhh

highlight('You searched for: rails', ['for', 'rails'], :highlighter => '<em>\1</em>')
# => You searched <em>for</em>: <em>rails</em>

highlight('You searched for: rails', 'rails', :highlighter => '<a href="search?q=\1">\1</a>')
# => You searched for: <a href="search?q=rails">rails</a>

You can still use highlight with the old API that accepts the highlighter as its optional third parameter:

highlight('You searched for: rails', 'rails', '<a href="search?q=\1">\1</a>')     # => You searched for: <a href="search?q=rails">rails</a>
