EMGM is a free and open source general-purpose Haskell library for generic programming with type classes.
The design is based on the idea of modeling algebraic datatypes as sum-of-product structures. Many datatypes can be modeled this way, and because they all share a common structure, we can write generic functions that work on this structure.
The library provides three main components:
- Common - A common foundation for building generic functions and adding support for datatypes. This includes the collection of datatypes (e.g. sum, product, unit) and type classes (e.g. Generic, Rep), that are used throughout the library. This is what you need to define your own generic functions, to add generic support for your datatype, or to define ad-hoc cases.
- Data - Support for using standard datatypes generically. Types such as [a], tuples, and Maybe are built into Haskell or come included in the standard libraries. EMGM provides full support for generic functions on these datatypes. The modules in this component are also useful as guides when adding generic support for your own datatypes.
- Functions - A collection of useful generic functions. These work with a variety of datatypes and provide a wide range of operations. For example, there is crush, a generalization of the fold functions. It is one of the most useful functions, because it allows you to flexibly extract the elements of a polymorphic container.

Main features:
- Datatype-generic programming using sum-of-product views
- Large collection of ready-to-use generic functions
- Included support for standard datatypes: lists, Maybe, tuples
- Easy to add support for new datatypes
- Type classes make writing new functions straightforward in a structurally inductive style
- Generic functions are extensible with ad-hoc cases for arbitrary datatypes
- Good performance of generic functions

System requirements:
- GHC

PyGTS is an open source and Python based package used to construct, manipulate, and perform computations on triangulated surfaces.
PyGTS is a hand-crafted and pythonic binding for the GNU Triangulated Surface (GTS) Library.

Main features:
- Simple object-oriented structure giving easy access to topological properties.
- 2D dynamic Delaunay and constrained Delaunay triangulations.
- Robust geometric predicates (orientation, in circle) using fast adaptive floating point arithmetic.
- Robust set operations on surfaces (union, intersection, difference).
- Surface refinement and coarsening (multiresolution models).
- Dynamic view-independent continuous level-of-detail.
- Preliminary support for view-dependent level-of-detail.
- Bounding-boxes trees and Kd-trees for efficient point location and collision/intersection detection.
- Graph operations: traversal, graph partitioning.
- Metric operations (area, volume, curvature ...).
- Triangle strips generation for fast rendering.

System requirements:
-

Enhancements
- Corrected internal typecasting for vertices. This fixes problems
- with using list of numbers as vertices.
- Improved cleanup code
- Build specifically for i386 of PPC under Mac OS X

htaGen is a project for managing the user file needed for securing access on apache web servers.
To secure a directory of a Apache web server you basically need two things: a user/password file and a .htaccess file.
You may use htaGen in order to generate the user file, but currently the htaccess needs to be created manually.

Main features:
- Multiple user files
- Group support
- Manage htaccess files
