Can I use Coffeescript and ERB in the same file and keep readable indentation?

Question

In Rails, I have a Coffeescript file in my views that gets rendered as the response to an AJAX request.

If I have some ERB control logic using <% %> , Id' like to be able to indent everything logically like I would in an HTML view:

exampleFunction = ->
  <% if condition %>
    alert("condition met!")
  <% else %>
    alert("condition not met!")
  <% end %>

But this usually means the Coffeescript throws indentation errors and won't compile. (The example I just gave might not fail, I haven't bothered to check, but it happens all the time in less contrived cases.)

So I have to indent things in this rather unwieldy way:

exampleFunction = ->
  <% if condition %>
  alert("condition met!")
  <% else %>
  alert("condition not met!")
  <% end %>

Is there any other way around this? Can I get Coffeescript and ERB to play nicely with eachother and allow for more readable indentation?

Answer 1

This doesn't quite answer the question, but I'd suggest setting variables using ERB, and then checking those in the logic instead - for example:

condition = <%= condition.to_s %>

exampleFunction = ->
    if condition
        alert("condition met!")
    else
        alert("condition not met!")

This will mean that all of the code is available when debugging/running, and makes the ERB template a lot easier to manage with regards to indentation.
