Haskell functions for working with posix paths
There are two primary modules, System.Posix.FilePath and
System.Posix.Directory.Traversals
System.Posix.FilePath provides an API for working with RawFilePath
paths (i.e. bytestrings). The API is largely compatible with the familiar
filepath module, although without windows-specific functionality (e.g. drives).
System.Posix.Directory.Traversals provides several functions to get the
contents of a directory structure. These are generally much faster than
similar functions defined elsewhere.
Current benchmarks compare performance of a directory traversal based upon a
well-known Haskell example, the same algorithm implemented with RawFilePath
instead of FilePath, the unix "find" utility, and this package's
allDirectoryContents, allDirectoryContents', and traverseDirectory.
