BlogMax makes it easy to use Emacs to maintain a Web log. You define templates and an FTP site for uploads. Most of your site's content is defined by text files. Saving a text file automatically wraps the template around it, expands macros and shortcuts, and saves the HTML file. Other commands in "weblog" mode upload files via FTP, create an RSS file, yank links or blockquotes into the buffer, create shortcuts, etc. The BlogMax Web site was, of course, created with BlogMax. It has been tested in Emacs 20.3.1 on Windows and Emacs 20.4.1 on Mandrake Linux.
CMUCL is a free, high performance implementation of the Common Lisp programming language which runs on most major Unix platforms. It mainly conforms to the ANSI Common Lisp standard. CMUCL provides a sophisticated native code compiler; a powerful foreign function interface; an implementation of CLOS; the Common Lisp Object System; which includes multimethods and a metaobject protocol; a source-level debugger and code profiler; and an Emacs-like editor implemented in Common Lisp. CMUCL is maintained by a team of volunteers collaborating over the Internet, and is mostly in the public domain.
DictEm is an extremely customizable DICT client for (X)Emacs. It implements all functions of the client part of the DICT protocol (RFC-2229). Unlike dictionary.el, it widely uses autocompletion that is used for selecting a dictionary and search strategy. It provides several hooks that may be used for buffer postprocessing. Built-in hyperlinking and a highlighting mechanism are based on this ability. It supports the mechanism of virtual dictionaries that can be used for grouping dictionaries from different DICT servers into the client-side virtual dictionary.
ILISP is a package that is designed to integrate various Lisp implementations (mostly Common Lisp systems and various Scheme dialects, including Guile) within Emacs (or XEmacs). ILISP runs an inferior Lisp process (in Emacs parlance) and provides a specialized set of commands, key bindings, and menus to ease the interaction with it. ILISP commands access the underlying Lisp process and provide ways to make the editing, compilation, and execution of Lisp programs much easier.
Emaigos imports Google contacts and calendars into Emacs. Contacts are stored in a Big Brother Database (BBDB) file, which makes them usable with many Emacs email packages, like Gnus. Google calendars are stored as a single Org-mode file, so events may be viewed as a structured document and possibly shown within an Agenda view. With Emaigos, it's possible to use Google as a contacts and calendars manager, while having all the same data available within Emacs. The original Google contacts and calendars are not modified in any way by Emaigos. The name "Emaigos" is an acronym for "EMAcs Importer for GOogle Stuff".
GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
