This package defines a class, 'Hashable', for types that can be converted to a hash value. This class exists for the benefit of hashing-based data structures. The package provides instances for basic types and a way to combine hash values.

Support code for reading and manipulating hashed file storage (where each file and directory is associated with a cryptographic hash, for corruption-resistant storage and fast comparisons). The supported storage formats include darcs hashed pristine, a plain filesystem tree and an indexed plain tree (where the index maintains hashes of the plain files and directories).

This package provides a couple of different implementations of mutable hash tables in the ST monad, as well as a type class abstracting their common operations, and a set of wrappers to use the hash tables in the IO monad.

Haskell-Source with Extensions (HSE, haskell-src-exts) is an extension of the standard haskell-src package, and handles most registered syntactic extensions to Haskell, including: * Multi-parameter type classes with functional dependencies * Indexed type families (including associated types) * Empty data declarations * GADTs * Implicit parameters * Template Haskell and a few more. All extensions implemented in GHC are supported. Apart from these standard extensions, it also handles regular patterns as per the HaRP extension as well as HSX-style embedded XML syntax.

The haskell-src package provides support for manipulating Haskell source code. The package provides a lexer, parser and pretty-printer, and a definition of a Haskell abstract syntax tree (AST). Common uses of this package are to parse or generate Haskell 98 code.

Produces ctags "tags" and etags "TAGS" files for Haskell programs.

Convert strings into hexadecimal and back.

Package 'bit64' provides serializable S3 atomic 64bit (signed) integers that can be used in vectors, matrices, arrays and data.frames. Methods are available for coercion from and to logicals, integers, doubles, characters and factors as well as many elementwise and summary functions. Many fast algorithmic operations such as 'match' and 'order' support interactive data exploration and manipulation and optionally leverage caching.

Contains several basic utility functions including: moving (rolling, running) window statistic functions, read/write for GIF and ENVI binary files, fast calculation of AUC, LogitBoost classifier, base64 encoder/decoder, round-off error free sum and cumsum, etc.
