Filters
Filters are modules that export their methods to liquid. All methods will have to take at least one parameter which represents the input of the filter. The return value will be the output of the filter.
module Jekyll
module AssetFilter
def asset_url(input)
"http://www.example.com/#{input}?#{Time.now.to_i}"
end
end
end
Liquid::Template.register_filter(Jekyll::AssetFilter)
ProTip™: Access the site object using Liquid
Jekyll lets you access the site
object through the
@context.registers
feature of Liquid at @context.registers[:site]
. For example, you can
access the global configuration file _config.yml
using
@context.registers[:site].config
.
