Dear all,

we already discuss about that in the moose and pharo mailing-list.
Maybe this is too late, but please find a small proposal for gsoc 2012 below.


Name: SciSmalltalk
Level: Intermediate
Possible mentor: Serge Stinckwich
Possible second mentor: ?

Smalltalk has at that time no equivalent to mathematical libraries
like NumPy, SciPy (Python) or SciRuby (Ruby).
The goal of the SciSmalltalk project is to develop an open-source
library of mathematical for the Smalltalk programming language (MIT

Technical Details
The development of this project is to be done in Pharo Smalltalk, but
the code should be portable to other Smalltalk flavors.
Numerous Smalltalk projects provide already some basic functionalities
(complex and quaternions extensions, random number generator, fuzzy
algorithms, LAPACK linear algebra package, Didier Besset's numerical
methods, ...). A first task will be to do an audit of all the existing
projects that provide some mathematical stuff and build a Pharo
Configuration to load them in a fresh Pharo Smalltalk image. After
that, the student help by his/her mentors will decide what are the
numeric algorithms to develop in priority.

The student will need to know some basic numeric algorithms usually
found in such libraries.
Units tests should also be provided.

Benefits to the Student
The student will help the Smalltalk community in a very concrete way.
The student will learn to design well-designed code with tests.

Benefits to the Community
Having a package providing more elaborate numeric libraries is really
important to develop the use Smalltalk in new domains (robotics, high
performance computing, computer vision, bio-computing, ...). The lack
of numeric librairies hamper the use of the Smalltalk in a scientific
context at the moment. An another goal of this project is to develop a
community of people interested by these topic.
