Build Status BSD Haskell

Documentation: memory on hackage

A generic memory and related abstraction for haskell:

  • A polymorphic byte array abstraction and function similar to strict ByteString.
  • Different type of byte array abstraction.
  • Raw memory IO operations (memory set, memory copy, ..)
  • Aliasing with endianness support.

Also provides some useful helpers:

Versioning

Development versions are an incremental number prefixed by 0. No specific meaning is associated with the versions, specially no API stability.

Production versions : TBD

Coding Style

The coding style of this project mostly follows: haskell-style

  • OSX >= 10.8
  • Linux

On the following architectures:

  • x86-64
  • i386

On the following haskell versions:

Changes

0.6

  • fix compilation on architecture where endianness is not a compile time define related to their cabal arch().

0.5

  • Add Base32 support (Nicolas Di Prima)
  • Fix build on 32 bit by simplifying scrubber, and adding Word64 type + operations compatibility

0.4

  • Add Ord instances for SipHash and FnvHash (Nicolas Di Prima)
  • Fix GHC-7.2 build by defining unsafeShiftL (Adam Bergmark)
  • Fix show instance of Bytes to properly display each bytes instead of just the end one
  • Add View type that emulate a view on a ByteArray type (Nicolas Di Prima)

0.3

  • fix missing modules from tests on sdist

0.2

  • make concat more generic as to what the output is going to be, and at the same time reduce the constraint on the input to just Access
  • make all byte array operation safer related to negative size. now replicate, zero, and alloc will returns an empty byte array when asking for negative size
  • replace ‘pack’ in Data.ByteArray.Pack by ‘fill’, as to not conflict with ‘Data.ByteArray.pack’. Also swap the length and monadic action to be more naturally used
  • add a deprecated ‘pack’ that alias to ‘fill’ for now
  • loosen constraint of Data.ByteArray.Pack.putBytes from ByteArray to ByteArrayAccess

0.1

  • Initial release
