How can I convert the below example to use an external file instead of the embedded lazy text quasi quotes?
{-# LANGUAGE QuasiQuotes, OverloadedStrings #-}
import Text.Shakespeare.Text
import qualified Data.Text.Lazy.IO as TLIO
import Data.Text (Text)
import Control.Monad (forM_)
data Item = Item
{ itemName :: Text
, itemQty :: Int
}
items :: [Item]
items =
[ Item "apples" 5
, Item "bananas" 10
]
main :: IO ()
main = forM_ items $ \item -> TLIO.putStrLn
[lt|You have #{show $ itemQty item} #{itemName item}.|]
This is from the yesod online book.
You can use the
textFile
function, along the lines of$(textFile "some-file")
.
