truncate(text, options = {}, &block)
Instance Public methods
Truncates a given text after a given :length if
text is longer than :length (defaults to 30). The
last characters will be replaced with the :omission (defaults
to ââ¦â) for a total length not exceeding :length.
Pass a :separator to truncate text at a natural
break.
Pass a block if you want to show extra content when the text is truncated.
The result is marked as HTML-safe, but it is escaped by default, unless
:escape is false. Care should be taken if
text contains HTML tags or
entities, because truncation may produce invalid HTML (such as unbalanced or incomplete tags).
