A compatibility layer for base Provides functions available in later versions of base to a wider range of compilers, without requiring you to use CPP pragmas in your code. See the README for what is covered. Also see the changelog for recent changes. Note that base-compat does not add any orphan instances. There is a separate package, base-orphans, for that. In addition, base-compat does not backport any data types or type classes. See this section of the README for more info. base-compat is designed to have zero dependencies. For a version of base-compat that depends on compatibility libraries for a wider support window, see the base-compat-batteries package. Most of the modules in this library have the same names as in base-compat-batteries to make it easier to switch between the two. There also exist versions of each module with the suffix .Repl, which are distinct from anything in base-compat-batteries, to allow for easier use in GHCi.

Various small helper functions for Lists, Maybes, Tuples, Functions Various small helper functions for Lists, Maybes, Tuples, Functions. Some of these functions are improved implementations of standard functions. They have the same name as their standard counterparts. Others are equivalent to functions from the base package, but if you import them from this utility package then you can write code that runs on older GHC versions or other compilers like Hugs and JHC. All modules are plain Haskell 98. The package depends exclusively on the base package and only that portions of base that are simple to port. Thus you do not risk a dependency avalanche by importing it. However, further splitting the base package might invalidate this statement. Alternative packages: Useful, MissingH

Golden tests support for tasty This package provides support for «golden testing». A golden test is an IO action that writes its result to a file. To pass the test, this output file should be identical to the corresponding «golden» file, which contains the correct result for the test. To get started with golden testing and this library, see Introduction to golden testing.

RFC 4648-compliant Base16 encodings for ByteStrings This package provides support for encoding and decoding binary data according to base16 (see also RFC 4648) for strict (see Data.ByteString.Base16) and lazy ByteStrings (see Data.ByteString.Base16.Lazy). See the base16 package which provides superior encoding and decoding performance as well as support for lazy, short, and strict variants of Text and ByteString values. Additionally, see the base-encoding package which provides an uniform API providing conversion paths between more binary and textual types.

Batteries included conduit: adapters for common libraries. The conduit package itself maintains relative small dependencies. The purpose of this package is to collect commonly used utility functions wrapping other library dependencies, without depending on heavier-weight dependencies. The basic idea is that this package should only depend on haskell-platform packages and conduit.
