How to compile a resource into a binary in Haskell?

Question

Say I have a dictionary.txt file, I need to read it into a map and use it in my program, how can I make this dictionary.txt file contained in the compiled exe f

Answer 1

You can store serialized data types as bytestring literals. Here's an example:

• http://code.haskell.org/~dons/code/compiled-constants/
• http://haskell.org/haskellwiki/Compiling_in_constants

However, the file-embed automates this process, making it easier to do non-trivial embeddings.

All approaches essentially boil down to representing the static data as a bytestring literal,

{-# LANGUAGE OverloadedStrings #-}

import Data.Binary
import qualified Data.Map as M
import qualified Data.ByteString.Char8 as S
import Data.ByteString.Lazy
import Codec.Compression.GZip

--
-- this is a gzip compressed literal bytestring, storing a binary-encoded Data.Map
