Broken url insertion in coffeescript about shakespeare

[gregwebs]

widgetFile works as designed. You need to override the implementation, not sure if there is documentation for that.

The error you get is from the shakespeareRuntime code path (I believe not finding your routes in scope). I would guess that it has nothing to do with coffeescript.

Exactly the same code works fine with other JavaScript template language and if overriding widgetFile to support coffee script means something completely different from overriding it for julius (other than providing different extension name and parsing functions - it is broken. Especially is there is no documentation explaining you why coffee script is that different from Julius from yesod's point of view.

As far as I understand whole idea of scaffold is in having some sane set of defaults that you can use as is without having to write this code yourself, unless you want something strange (like using head or tail functions from Prelude, heh :) ).

This has been addressed in yesod devel, but as Greg mentioned, there's no built-in support for Coffeescript in widgetFile. If we include Coffeescript with the same level of control as Julius is supported, this problem will be resolved.

Is there documentation somewhere on how to override widgetFile?

widgetFile :: String -> Q Exp 
widgetFile = (if development then widgetFileReload else widgetFileNoReload )
    widgetFileSettings
  where
    widgetFileSettings = def { wfsLanguages = λhset → defaultTemplateLanguages hset ⧺
        [ 
          TemplateLanguage True  "coffee"  Text.Coffee.coffeeFile   Text.Coffee.coffeeFileReload
      ] }

I copied that information to https://github.com/yesodweb/yesod/wiki/Overriding-widgetFile, and I'll link to that Wiki page from the scaffolding. Should we close this issue?
