truncate(truncate_at, options = {}) click to toggle source

Truncates a given text after a given length if text is longer than length:

'Once upon a time in a world far far away'.truncate(27)
# => "Once upon a time in a wo..."

Pass a string or regexp :separator to truncate text at a natural break:

'Once upon a time in a world far far away'.truncate(27, separator: ' ')
# => "Once upon a time in a..."

'Once upon a time in a world far far away'.truncate(27, separator: /\s/)
# => "Once upon a time in a..."

The last characters will be replaced with the :omission string (defaults to “…”) for a total length not exceeding length:

'And they found that many people were sleeping better.'.truncate(25, omission: '... (continued)')
# => "And they f... (continued)"
# File pantograph_core/lib/pantograph_core/string_filters.rb, line 20

  return dup unless length > truncate_at

  omission = options[:omission] || '...'

      rindex(options[:separator], length_with_room_for_omission) || length_with_room_for_omission
