Constructor Details

#initialize(tag_name, raw_params, tokens) ⇒ Picture

First jekyll initializes our class with a few arguments, of which we only care about the params (arguments passed to the liquid tag). Jekyll makes no attempt to parse them; they’re given as a string.

Instance Method Details

#render(context) ⇒ Object

Then jekyll calls the ‘render’ method and passes it a mostly undocumented context object, which appears to hold the entire site including its configuration and the parsed _data dir.
