Lisp Blosxom is a port of the Perl Blosxom blogging engine to ANSI Common Lisp. Its goals are extensibility and speed. It's a filesystem-based blogging engine, which means that blog entries are just flat files on disk, although plugins can be written to extend or replace this behavior. The first line in the file is the title, while the remainder is the text of the body. Entry dates are taken directly from the filesystem's modification date for each entry. Furthermore, the structure of the blog is taken directly from the hierarchy of directories and files on disk.
InteLib is a library of C++ classes that lets you do Lisp/Scheme programming within your C++ programs, even without any additional preprocessing, without all those calling conventions. You can write code that is accepted by a C++ compiler while thinking in a "Lisp/Scheme mode", and the code you write will look much like Lisp/Scheme code, although it will be pure C++.
sawfish.wm.ext.pager is a C/Lisp extension that provides a functional desktop pager for the sawfish window manager. A pager is a map of your desktop. It shows not only the visible part of your desktop (the current viewport), but also the parts that extend beyond the sides of your screen. Also, if you have more than one workspace, the pager will follow you to where you are, or optionally show all workspaces at once. Of course you can select viewports and windows, and also move or raise/lower the latter.
The lisp-cgi-utils is a software package for developing CGI scripts with Common Lisp. It implements a very basic HTTP/CGI interface (sending headers, getting GET/POST and environment variables) and offers tools for easier HTML generation with special support for handling HTML forms.
LIME is a dynamic programming language with a LISP-like syntax. It features partial function application, eager and lazy evaluation, call-by-value and call-by-reference, macros, reading/writing LIME code as data, a standard library including infinite streams, and an interactive mode with auto-indentation.
HALoGEN is an extremely powerful and easy to use general-purpose natural language generation system. It consists of a symbolic generator, a forest ranker, and some sample inputs. The symbolic generator includes the Sensus Ontology dictionary based on WordNet. The forest ranker includes a 250 million word ngram language model (unigram, bigram, and trigram) trained on the Wall Street Journal newspaper text. The symbolic generator is written in LISP and requires a Lisp interpreter.
REDLisp is currently only an interpreter of a new dialect of Lisp. It already has GTK and SDL_mixer support. Functions partially work. Macros will be added very soon, as will classes, multiplatform sockets, and threads. REDLisp isn't meant to replace any current Common Lisp implementation, but is just a pet project of a college student.
