Internal: Extract excerpt from the content
By default excerpt is your first paragraph of a post: everything before the first two new lines:
--- title: Example --- First paragraph with [link][1]. Second paragraph. [1]: http://example.com/
This is fairly good option for Markdown and Textile files. But might cause problems for HTML posts (which is quite unusual for Jekyll). If default excerpt delimiter is not good for you, you might want to set your own via configuration option `excerpt_separator`. For example, following is a good alternative for HTML posts:
# file: _config.yml excerpt_separator: "<!-- more -->"
Notice that all markdown-style link references will be appended to the excerpt. So the example post above will have this excerpt source:
First paragraph with [link][1]. [1]: http://example.com/
Excerpts are rendered same time as content is rendered.
Returns excerpt String
# File lib/jekyll/excerpt.rb, line 107 def extract_excerpt(post_content) separator = site.config['excerpt_separator'] head, _, tail = post_content.partition(separator) "" << head << "\n\n" << tail.scan(/^\[[^\]]+\]:.+$/).join("\n") end
