AsmEdit 'AsmEdit' is an editor and IDE written in assembler. It includes source highlighting and support for external helper programs for compiling and debugging. It contains word processing features such as paragraphing and spelling in a binary of less than 20,000 bytes.

Astyle Artistic Style is a fast and small reindenter and reformatter of C, C++ and Java source codes. Using a series of filters, astyle takes code written in one editor and automatically reindents and reformats the source code files to eliminate unneeded spaces and tabs and standardize the look of the code.

Bless Bless is a fast and customizable hex editor written in GTK#. It efficiently handles very large files and supports multiple undo-redo actions. There are also plans for the addition of a Lua-based scripting language for binary file manipulation.

DVC for Emacs DVC is a common Emacs front-end for a number of distributed version control systems. It currently supports GNU Arch, Bazaar, git, Mercurial, and Monotone. Support for Darcs is being worked on but still lacks some features.

Easymacs 'Easymacs' is an easy-to-learn configuration for new users of GNU Emacs. It sets up key bindings that conform to a common denominator of the Gnome/KDE/OS human interface guidelines, and provides function-key bindings for other powerful Emacs features. It is fully documented, and the new user can productively edit text right away, without going through the Emacs tutorial. Users can access many commonly-used functions without learning the "chords" or multiple keystrokes that Emacs uses by default.

Emacs Extraordinarily powerful text editor with additional features including content sensitive major modes, complete online documentation, highly extensible through Lisp, support for many languages and their scripts through its multilingual extension, and a large number of other extensions available either separately or with the GNU Emacs distribution. Runs on many different operating systems regardless of machine. It offers true Lisp, smoothly integrated into the editor, for writing extensions and provides an interface to the X windows system.

IDLEfork The IDLEfork project is an official experimental development fork of Python's small, light, 'bundled' integrated development environment, IDLE. Its objective is to develop a version of IDLE which had an execution environment which could be initialized prior to each run of user code.

Indent 'indent' changes the appearance of a C program by inserting or deleting whitespace. It also has options for controlling the alignment of braces and declarations, program indenting, formatting of both C and C++ comments. and other stylistic parameters.

Led Led is a small, fullscreen text editor for unix, primarily intended for use as a programming editor. Programming modes do syntax highlighting and can do auto indentation. Keybindings, colors, and general options may be changed in each user's ~/.ledrc file. Features include multiple buffers, unlimited undo, better text killing commands, improved isearch and reverse searching, vertical and horizontal split screens, improved syntax highlighting, optional Perl scriptability, and an extensible, stackable view architecture which will someday be explained here.

PyPE PyPE (Python Programmers Editor) was written in order to offer a lightweight but powerful editor for those of you who think emacs is too much and idle is too little. Syntax highlighting is included out of the box, as is multiple open documents via tabs. Since it is written in Python and wxPython, PyPE can be used on basically every platform available.
