-- Hoogle documentation, generated by Haddock -- See Hoogle, http://www.haskell.org/hoogle/ -- | Use Template Haskell to embed file contents directly. -- -- Use Template Haskell to read a file or all the files in a directory, -- and turn them into (path, bytestring) pairs embedded in your Haskell -- code. @package file-embed @version 0.0.11 -- | This module uses template Haskell. Following is a simplified -- explanation of usage for those unfamiliar with calling Template -- Haskell functions. -- -- The function embedFile in this modules embeds a file into the -- executable that you can use it at runtime. A file is represented as a -- ByteString. However, as you can see below, the type signature -- indicates a value of type Q Exp will be returned. In order to -- convert this into a ByteString, you must use Template Haskell -- syntax, e.g.: -- --
-- $(embedFile "myfile.txt") ---- -- This expression will have type ByteString. Be certain to -- enable the TemplateHaskell language extension, usually by adding the -- following to the top of your module: -- --
-- {-# LANGUAGE TemplateHaskell #-}
