FYI the latest versions of universal-ctags come with markdown and scss configurations out of the box (and even yaml if compiled with libyaml support).

I've had problems with it though, so I have reverted back to an old version and your configuration comes in handy, especially the yaml one. Thanks!

@jeromedalbert thanks for the heads up.

thanks for the YAML definition, now I can jump back to variable definitions for my Ansible
