hexdump-lazy

A Haskell library that produces hex dumps lazily from various types of source.

The output is a list of lines with type [String]. Each line represents 16 bytes in the input.

Possible inputs include [Word8], ByteString and Ptr a.

The library itself has no dependencies beyond base and bytestring.

Example Output

$ cabal repl
λ> import qualified Data.ByteString as BS
λ> fp = "dist-newstyle/packagedb/ghc-8.10.2/package.cache"
λ> bs <- BS.readFile fp
λ> putStr . unlines . take 16 $ hexDumpByteString bs
