[web-devel] problems using yesod scaffolding

running yesod with the mini option caused some problems. I got
complaints of not being able to find Settings.hs, so I made some
changes to the import statements.
Also, I changed the directory config to Config to accommodate my changes.

Here's what the import sections look like now


module Aframe
    ( Aframe (..)
    , AframeRoute (..)
    , resourcesAframe
    , Handler
    , Widget
    , module Yesod.Core
    , module Config.Settings  <---- made a change here
    , StaticRoute (..)
    , lift
    , liftIO
    ) where

import Yesod.Core
import Yesod.Helpers.Static
import qualified Config.Settings as Settings  <---- made a change here
import System.Directory
import qualified Data.ByteString.Lazy as L
import Config.Settings (hamletFile, cassiusFile, juliusFile,
widgetFile) <----- made a change here
import Config.StaticFiles <----- made a change here
import Control.Monad (unless)

{-# LANGUAGE TemplateHaskell #-}
{-# LANGUAGE MultiParamTypeClasses #-}
{-# LANGUAGE OverloadedStrings #-}
{-# OPTIONS_GHC -fno-warn-orphans #-}
module Controller
    ( withAframe
    , withDevelApp
    ) where

import Aframe
import qualified Config.Settings as Settings <---- made a change here
import Yesod.Helpers.Static
import Data.ByteString (ByteString)
import Network.Wai (Application)
import Data.Dynamic (Dynamic, toDyn)

that said, I get out of scope errors when I try to run the scaffolding
generated code

Aframe withDevelApp
Attempting to interpret your app...
Compile failed:

Not in scope: `withDevelApp'

also get the same problem when trying withAframe

I can't see the reason for the out of scope problem. I think it has to
do with the changes I made. Anything suspicious pop out for anyone?
