Free emacs like software for linux

Emacs::Lisp provides support for writing Emacs extensions in Perl.

Emacs allows you to customize your environment using Lisp. With EPL, you can use Perl, too. This module allows Perl code to call functions and access variables of Lisp.

You still need to learn some Lisp in order to understand The Elisp Manual, which is the definitive reference for Emacs programming. This document assumes a basic understanding of Emacs commands and Lisp data types. I also assume familiarity with Perls complex data structures (described in perlref) and objects (see perlobj).

Perlmacs was (is?) a project that embedded a Perl interpreter into the Emacs binary so that it could run Lisp, Perl, or any combination of the two. It uses Perls C interface, which requires patching and recompiling Emacs. As a result, each release is tied to a version of Emacs, it takes a lot of time and disk space to build, and it is not very portable.

EPL (Emacs Perl) accomplishes most of what Perlmacs can do, but it does not suffer from the same drawbacks. It uses unmodified Emacs and Perl and lets them work together through IPC (pipes). This may make some tasks much slower, but it is much more convenient to install and upgrade, and it works with XEmacs as well as Emacs 21 betas.

Easymacs is an easy-to-learn, one-size-fits-all configuration for new users of GNU Emacs. The project sets up key bindings that conform to a common denominator of the Gnome/KDE/OS X/Microsoft Windows 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. Many commonly-used functions can be accessed without having to learn the "chords" or multiple keystrokes that Emacs uses by default.
Humanists:
Easymacs was designed with the non-programmer in mind, someone who would like to use Emacs to edit mainly text files, especially LaTeX and TEI-conforming XML. Since many aspects of the configuration of Emacs require a certain knowledge of programming, this sort of person might find the default behavior of Emacs too foreign and too hard to reconfigure.
Programmers:
On the other hand, Easymacs is also a great environment for programmers who would like to use Emacs, but dont want to spend the time in learning how to configure it.
Main features:
- All of the usual features of an editor: undo, redo, search and replace, intelligent indentation and wrapping.
- Spell-checking as you type. This distinguishes between true misspellings and words which are used more than once in a file, and so are likely to be correct but unknown. You can correct misspellings with a single keystroke (F8).
- There are many convenient ways of entering non-ASCII text, including Unicode and various exotic encodings.
- Rectangular selection of text, which can be also used to insert the same text in many columns (Ctrl-Return).
- Most file-types define syntax-sensitive folding (F7).
- Visible, persistent bookmarks to mark particular lines in a file (Alt-F2).
- You can search for text in multiple files in a given folder or set of subfolders (Ctrl-Shtf-F9). The output displays a menu of the lines in the different files that match a your pattern, and you can jump from one to the next with a single keystroke (F10 or Alt-`).
- Auto-completion of words based on the content of other open files (F5), or on a dictionary (Shft-F8).
- Multiple cut and paste clipboards (just hit Ctrl-number before cutting, copying or pasting, and the commands will use the clipboard numbered 0-9 for that operation).
- History of clipboard contents: you can browse through the past contents of the clipboard and insert any one of the previous contents (Shft-Ctrl-V).
- Keyboard macros that let you record (Alt-Shft-F5) and play back (Alt-F5) a series of keystrokes, to ease repetitive tasks.
- You can look up the word at the cursor in dictionaries and thesauri with a single keystroke (Alt-F8).
- You can easily switch between open files via a menu (F9), or other quick shortcuts (Shft-F9, Ctrl-F9). There is also a menu of recently opened files (Alt-Shft-F1).
- There is a full command shell for manipulating files and running commands. (Alt-F9).
Enhancements:
- A number of small updates and additions were made.
- At a minimum, the forthcoming Emacs 22 is required.

Emacs Chess is an object-oriented library written in Elisp for manipulating chess objects (games, plies, positions, etc.), and for displaying them.
Main features:
- Emacs Chess is also an object-oriented library for manipulating chess objects (games, plies, positions, etc), and for displaying them. It supports a wide range of engine objects to use as move sources. This what allows chess.el to act as a chess client.
- chess-announce.el announces your opponents moves verbally, such as "knight takes at f4"provided you have "festival" installed.
- chess-sound.el is similar to chess-announce, but uses specific WAV files for each sound used. It takes up much more disk space, but is nicer to listen to. Available in English only at the moment.
- chess-irc.el provides a tiny IRC bot, allowing you to play games over IRC so long as your opponent enters moves in short algebraic notation. If they dont have chess.el, all they need is a regular chessboard, and a knowledge of SAN (short alegebraic notation).
- chess-ics.el lets you to play on Internet Chess Servers, using chess.el as your chessboard display (which means chess-announce works with it, etc). It has only been tested with FICS so far.
- chess-crafty.el, chess-gnuchess.el and chess-phalanx.el let you play against the Crafty, Gnuchess and Phalanx engines.
- chess-random.el will create Fischer Random positions to play against. Note that this feature only really works against opponents who are also using chess.el. Simply type "S" in the chessboard display buffer to setup a Fischer Random starting position.
- chess-network.el lets you play against other chess.el users directly, over a single open port on the server side. To be a server, you must have "netcat" installed, or be using Emacs 21.3 or higher (which supports server side network sockets). To be a client, all you need is Emacs 21.1 or higher.
- chess-link.el lets you tie two engines together, so that events from one are responded to by events from another. This can let you run a chess bot on your computer over any of the transport, or you can use it to pit two computer chess engines against each other.
- chess.el can even export chessboard display to other X servers, allowing you to play against people in your meeting room, even if they dont have Emacs installed!
Enhancements:
- This maintenance release includes several bugfixes.

KDM Vista like Theme is a very nice KDM theme that looks like Vistas one.
I didnt see any Vista like KDM login theme... I wanted one so I tried.
Enhancements:
- There are now two themes. One for widescreen which is the same as the previous one and one for 4/3 screen. This new one has been successfully tested on a 1600 x 1200 screen. If you have other resolution, please try and report if it works.

C# for Emacs is a derived mode implementing most of the C# rules.

After a good number of years, we noticed that there wasnt a "non-patched" version of a csharp-mode for Emacs.

There were a few, but most of them had comments that they were "in progress" or "about to merge", but then we noticed that those notices were there even after a couple of months.

Then, we saw a request for a csharp-mode on the cc-mode Emacs site, so we decided to follow the rules and create one that required no patching or modification to the core cc-mode engine (which is a good thing). So, this is the C# mode.
There was a 0.3.0 version, but it broke things more than it fixed, so we pulled it.

GNU TeXmacs is a free scientific text editor, which was both inspired by TeX and GNU Emacs. The editor allows you to write structured documents via a wysiwyg (what-you-see-is-what-you-get) and user friendly interface.
New styles may be created by the user. GNU TeXmacs implements high-quality typesetting algorithms and TeX fonts, which help you to produce professionally looking documents.
The high typesetting quality still goes through for automatically generated formulas, which makes TeXmacs suitable as an interface for computer algebra systems. TeXmacs also supports the Guile/Scheme extension language, so that you may customize the interface and write your own extensions to the editor.
Converters exist for TeX/LaTeX and they are under development for Html/MathML/Xml. In the future, TeXmacs is planned to evolve towards a complete scientific office suite, with spreadsheet capacities, a technical drawing editor and a presentation mode.
Enhancements:
- The user interface for the graphical mode has been simplified and the Maxima interface has been updated.
- Further progress was made for the upcoming new GUI.

Emacs Configuration Framework is a versatile configuration package for Emacs. It is meant for users whose Emacs configuration has become so complex that it appears to be unmanageable.
It enables you to write and load the configuration for individual Emacs packages in pieces. You can use it to setup some autoloads for a package when you start Emacs and then do extra configuration after the package has loaded.
This speeds up your Emacs startup without compromising your ability to do complicated things.
Enhancements:
- This release adds a new rc.d/lang directory.
- Modes added: speedbar, semantic, cedet, and ecb.
