Applications and libraries/Operating system

Standalone implementations of operating systems in Haskell

• House

Filesystems

• Fuse David Roundy's combination of a nice DarcsIO-style filesystem interface on the Haskell side (called FuseIO) with an interface to libfuse (which is a library for creating filesystems from user space on linux).

• Jeremy Bobbio's fuse bindings

• Halfs, the Haskell Filesystem

• ZipperFS is Oleg Kiselyov's file server/OS where threading and exceptions are all realized via delimited continuations.

Dynamic linking

• hs-plugins Library support for dynamically loading Haskell modules, as well as compiling source or eval code fragments at runtime.

Shell

Link collections on pure functional shells

• on Lambda the Ultimate
• Thesis Topic: The Design and Implementation of a Functional Shell

Haskell shell examples

HsShellScript

A library for using Haskell for tasks which are usually done by shell scripts, e.g. command line parsing, analysing paths, etc. It can be used also for tasks usually done GetOpt (a module for GNU-/POSIX-like option handling of commandline arguments). But also for many other things.

Jim Mattson's Hsh Haskell shell

on the software page by Ralf Hinze. Hsh seems to be written in Haskell 1.3.

HaSh

a nascent project page on a shell scripting system

Monadic i/o and UNIX shell programming

UNIX pipes as IO monads.

shell-haskell

library for communicating with other processes via Haskell code

Shell utilities

haskell-ls

A (near-)clone of the GNU ls utility.

h4sh

h4sh provides a set of Haskell List functions as normal unix shell commands. This allows us to use Haskell in shell scripts transparently. Each program is generated from the corresponding Haskell function's type
