SmartExcerpt

Allows to create intellegent excerpt fields.

This is an extraction from RocketCMS

Add this line to your application's Gemfile:

gem 'smart_excerpt'

And then execute:

$ bundle

Or install it yourself as:

$ gem install smart_excerpt

You have two fields: a mandatory text and an optional excerpt. If your excerpt field is empty, it generates an excerpt of a given length from text. It will also truncate excerpts if they are more than 20% longer then allowed value

Add two fields: excerpt and text

Add it to your model:

class Article
  ...
  include SmartExcerpt
  smart_excerpt :excerpt, :text
end

Then display excerpt:

Article.first.get_excerpt

All excerpts are passed through strip_tags and html entity decode.

Article.first.get_excerpt(25) # same as {words: 25}
Article.first.get_excerpt(letters: 25)
Article.first.get_excerpt(sentences: 5)
Article.first.get_excerpt(trust_multiplier: 3) # allow for much longer manual excerpts
Article.first.get_excerpt(trust_excerpts: true) # allow any manual excerpts
Article.first.get_excerpt(keep_headers: true) # do not remove HTML headers from excerpt
Article.first.get_excerpt(keep_newlines: true) # do not remove newlines from excerpt
Article.first.get_excerpt(keep_html: true) # do not remove HTML tags from excerpt (might be unsafe/dangerous!)
