truncate

Truncates a given text to length truncate_to if text is longer than truncate_to:

'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 “…”). The total length will not exceed truncate_to unless both text and :omission are longer than truncate_to:

'And they found that many people were sleeping better.'.truncate(25, omission: '... (continued)')
# => "And they f... (continued)"

'And they found that many people were sleeping better.'.truncate(4, omission: '... (continued)')
# => "... (continued)"
