Applications and libraries/Operating system

Standalone implementations of operating systems in Haskell

House

House is a platform for exploring various ideas relating to low-level and system-level programming in a high-level functional language, or in short for building operating systems in Haskell.

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).

hfuse

Jeremy Bobbio's fuse bindings

Halfs, the Haskell Filesystem

ZipperFS

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
