Arch Haskell News: Mar 14 2009: 1000 Haskell Packages

We’ve reached a milestone: more than 1000 Haskell packages packaged up for Arch Linux.

Hackage now has 1163 (+41) Haskell packages, of which 1007 (+33) have been natively packaged for Arch in AUR. That’s 33 new packages in two weeks, and lots of updates as well.

Here’s this week’s updates, broken down by category, so you can get a sense for what’s new in your area of interest:

Algorithm

Concurrency

Control

Cryptography

Data

Database

Devel

Graphics

Language

Network

System

Testing

Text

Web

Xml

Chart: A library for generating 2D Charts and Plots

Chart is a fairly mature Haskell library by Tim Docker for generated nice 2D plots and graphs using GTK/Cairo. It is now available in AUR. Here’s a demo doing some simple graphs from the command line.

SG: Small OpenGL geometry library for vectors and collision detection

SG is a small geometry library by Neil Brown for dealing with vectors, points, lines, simple shapes, and their various intersection tests written in Haskell. It is now available in AUR. You can try it out with the sgdemo app.

Here’s a video exercising the library.

On Arch Linux, you can get it with:

$ yaourt sgdemo

Everywhere else, with:

$ cabal install sgdemo

Stand back! haskell-regex-tdfa reaches 1.0.0

Chris Kuklewicz announced, enthusiastically, the release of haskell-regex-tdfa 1.0. You can now get  the Arch Linux package for it here. Amongst the varied and many regex libs for Haskell regex-tdfa stands as being 100% Haskell (not a binding to a C library), and for its use in the Yi project.

To quote Chris on the 1.0 release:

I am proud of this release.
This is not just a bug fix release.
It is a serious improvement in the asymptotic running time.

The previous versions allowed bad combinations of pattern and searched text length to scale badly in the length of the text. Previously the worst case for text of length N was O(N^3).

The new worst case asymptotic runtime scaled as O(N).
There is never any backtracking.
And the worst case storage space is independent of N.

Good work, Chris, and thanks for all the regex packages.
