Embed at compile time
embedFile :: FilePath -> Q Exp
Embed a single file in your source code.
import qualified Data.ByteString myFile :: Data.ByteString.ByteString myFile = $(embedFile "dirName/fileName")
Embed a directory recusrively in your source code.
import qualified Data.ByteString myDir :: [(FilePath, Data.ByteString.ByteString)] myDir = $(embedDir "dirName")
getDir :: FilePath -> IO [(FilePath, ByteString)]
Get a directory tree in the IO monad.
This is the workhorse of embedDir
Inject into an executable
dummySpace :: Int -> Q Exp
Arguments

| -> Maybe ByteString | new BS, or Nothing if there is insufficient dummy space |
Arguments
| :: ByteString | |
| -> FilePath | template file |
| -> FilePath | output file |
