NO LONGER MAINTAINED. There are surely better tools for this out there now.

h1. AutoExcerpt

pre. [sudo] gem install auto_excerpt

Creates excerpts of html formatted text.

pre. AutoExcerpt.new("This is some fancy html formatted text homie", {:words => 5}) # => "This is some fancy html..."

h3. Features

• There are 4 different ways to limit the length of an excerpt: characters, words, sentences, paragraphs
• If the excerpt would be shorter than the limit that is set, the entire text will be shown.
• If limiting by characters the gem will ensure that the excerpt does not cutoff in the middle of a word.
• HTML can be stripped. You can also set specific tags that you don't want stripped.
• HTML tags are automatically closed.

h3. Options

@:characters@ The number of characters to display from the text. Default: 150 (does not need to be set to 0 if you choose another option)
