[Jellyj-public] JellyJ Presentation

[Mohammad M. A. <am...@ce...>]

Dear Mr. Jaberipur
Salaam

This is a breif Overview of the JellyJ Project:
At Mar. 2002 (when we got the compiler course) we started the JellyJ 
project to design a simple (educational) object oriented programming 
language and write its compiler. Our motivation for it, was the compiler 
project as well as fulfilling our interest in designing a programming 
language. For this purpose, we started to read a good amount of papers and 
documents (to gain the minimum knowledge for designing a language and 
implementing its compiler). Fortunately, with a semi-continous work we 
finished design of the language as well as developing of its compiler.
The project was born on sourceforge and without dept it was licensed under 
one of open source licenses (LGPL). Now, we are proud to inform you about 
our job (in both compiler developing aspects and language design).

But unfortunately, at the last semester, despite of having a complete 
version of the compiler, we lost 3.5 points of our score (with the 
assumption that our project [as the best project which was done by last 
semester students] could gain the full score of project and even some an 
extra point). In our last semester plan, we had decided to present this 
project (and the work which was done for the JellyJ language design) in 
the Programming Language Design course as well. (because we beleive that 
our a good portion of our work was reading documents about language design  
aspects of an educational OO programming language)

The site is now up to date(http://jellyj.sourceforge.net). You can find 
there all the source and executable JellyJ compiler(from the Download 
menu). JellyJ API & Class Diagrams are available too, which uses java 
applets in its pages and you need to have a JVM installed on your machine 
to view the applet. The JellyJ lexer & parser is in the format of JavaCC 
Lexer & Parser Generator Tool(.jj file) which is accessible from the page.
As you can see, much more work than just a compiler implementation is done
in the JellyJ project. A list of some programming language concepts
efforts are available from the "Documents" and "Session Reports" menu in
the first page. Also, much more studies have been done on other Object
Oriented Languages such as Blue, SmallTalk & Eiffel, which their links are 
put in the "Resources" menu.
Please contact us for any problems with the site or to set a meeting time 
if necessary.

  Sincerely
-- JellyJ Design Group
