Ever needed to convert erb to haml?
Just use the Html2Haml Tool provided at http://html2haml.heroku.com/.
Here's another gem that I use all of the time: http://www.htmltohaml.com
Did you ever tried this link? Even by name you can see that it's HTML to HAML converter, instead of ERB to HAML
Yup I tried it back than, and was happy with the results. I did check again if ERB can still be converted, and it works.
Did it work for you?
Found this online tool to convert erb to slim work perfectly https://erb2slim.herokuapp.com
<%= form_tag do %>

If you are using Atom, you can also use their Html2Haml converter plugin https://atom.io/packages/html2haml without even leaving your editor ;)
