Hi Nathan,
Thanks for the advice but I'm not having any joy unfortunately.
I've placed the following in lib/kramdown_filter.rb
module KramdownFilter
include Haml::Filters::Base
def render(text)
::Kramdown::Document.new(text).to_html
end
end
I require the module in the environment.rb;
require 'kramdown_filter'
Then in my haml templates I use
:kramdownfilter
#[email protected]}
But I still get "Filter "kramdown_filter" is not defined."
Any help is greatly appreciated.
Sid
