Last active September 15, 2015 20:44

Custom renderer for redcarpet to render paperclip - images by their id and additional css


	# quick'm'dirty way to allow paperclip image-ids
	# instead of urls be passed to Redcarpet
	# so you can do:
	# ![title](42 'thumb\|pull-right') - whereas 'thumb' is your available paperclip-style and 'pull-right' a css-class
	# and also the knwon way:
	# ![title](http://i.ytimg.com/vi/Z6po6SS9Uz4/maxresdefault.jpg "my alt text")
	# all this b'cause there is no 'super' in redcarpet...
	#

my try to get turbolinks work with (piwik) javascript tracking somehow its not relayable - dunno why... it tracks sometimes - but not to the expected degree... figured out, that tracking works as today in firefox 26.0 on Linux as well as on Android Standard (safari-based?) Browser (4.3) - but on Chrome Version 31.0.1650.63 on Linux as well as an…
