Can I use a Coffeescript `switch` block in eco?

Can I use a Coffeescript switch block in the eco templating engine? I tried a couple of variations, but I keep getting unexpected dedent errors.

Update: To appease the downvoters, here is what I expected to work

<% switch x : %>
<% when 1 : %>
    one
<% end %>
<% when 2 : %>
    two
<% end %>
<% end %>

But I get "Parse error on line 5: unexpected dedent"

Solution

  • ECO templates don't appear to support the switch statement.

    The generated CoffeeScript code for your code is:

    switch x
  __out.push '\n'
  when 1
    __out.push '\n    one\n'
  __out.push '\n'
  when 2
    __out.push '\n    two\n'
  __out.push '\n'

    The two __out.push '\n' lines after switch x and the end of the second when statement don't seem to allow this CoffeeScript snippet to compile into JavaScript.

    Looking through the code, I couldn't figure out how to prevent those lines from being printed. This might be a good bug to report to the guys that make eco.
