Building a Template Handler with Markdown + ERB
Several gems can compile Markdown syntax to HTML. For our template handler, letâs use RDiscount,[24] which is a Ruby wrapper to the fast Markdown compiler library called Discount, written in C.
Markdown Template Handler
We can create a template handler that compiles to Markdown in just a couple lines of code. Letâs first add another test to our suite:
| handlers/1_first_handlers/test/integration/rendering_test.rb | |
| â | test â".md template handler"â âdoâ |
| â | get â"/handlers/rdiscount"â |
| â | expected = â"<p>RDiscount is <em>cool</em> and <strong>fast</strong>!</p>"â |
| â | assert_match expected, response.body |
| â | âendâ |
And then letâs write our template in the filesystem:
| handlers/1_first_handlers/test/dummy/app/views/handlers/rdiscount.html.md ... |
