ghc-base-compat 0.9.3 — Haskell compiler compatibility library

This library provides functions available in later versions of base to a wider range of compilers, without requiring the use of CPP pragmas in your code.

ghc-base-orphans 0.6 — Orphan instances for backwards compatibility

This package defines orphan instances that mimic instances available in later versions of base to a wider (older) range of compilers.

ghc-base-prelude 1.2.0.1 — The most complete prelude formed solely from the Haskell's base package

This Haskell package aims to reexport all the non-conflicting and most general definitions from the "base" package.

This includes APIs for applicatives, arrows, monoids, foldables, traversables, exceptions, generics, ST, MVars and STM.

This package will never have any dependencies other than "base".

Versioning policy:

The versioning policy of this package deviates from PVP in the sense that its exports in part are transitively determined by the version of "base". Therefore it's recommended for the users of ghc-base-prelude to specify the bounds of "base" as well.

ghc-base16-bytestring 0.1.1.6 — Fast base16 (hex) encoding and decoding for ByteStrings

This package provides a Haskell library for working with base16-encoded data quickly and efficiently, using the ByteString type.

ghc-binary 0.8.4.1 — Binary serialisation for Haskell values using lazy ByteStrings

Efficient, pure binary serialisation using lazy ByteStrings. Haskell values may be encoded to and from binary formats, written to disk as binary, or sent over the network. The format used can be automatically generated, or you can choose to implement a custom format if needed. Serialisation speeds of over 1 G\/sec have been observed, so this library should be suitable for high performance scenarios.

ghc-blaze-builder 0.4.0.2 — Efficient buffered output

This library provides an implementation of the older blaze-builder interface in terms of the new builder that shipped with bytestring-0.10.4.0.

It is suitable for high performance use, both in terms of large data quantities, or high speed requirements. The 'ByteString' functions follow the same style as ordinary lists, so it is easy to convert code from using 'String' to 'ByteString'.

ghc-bytestring-builder 0.10.8.1.0 — The new bytestring builder, packaged outside of GHC

This package provides the bytestring builder that is debuting in bytestring-0.10.4.0, which should be shipping with GHC 7.8. Compatibility package for older packages.

This library provides extensible optionally-pure exceptions for Haskell.

ghc-executable-path 0.0.3.1 — Find out the full path of the executable

The documentation of System.Environment.getProgName says that "However, this is hard-to-impossible to implement on some non-Unix OSes, so instead, for maximum portability, we just return the leafname of the program as invoked." This library tries to provide the missing path.
