Free gnu software for linux

GNU Go is a free program that plays the game of Go. GNU Go has played thousands of games on the NNGS Go server.

GNU Go is now also playing regularly on the Legend Go Server in Taiwan, on the WING server in Japan, and many volunteers run GNU Go clients on KGS. GNU Go has established itself as the leading non-commercial go program in the recent tournaments that it has taken part in.

GNU EMMS is the Emacs Multimedia System. It tries to be a clean and small application to play multimedia files from Emacs using external players. Many of its ideas are derived from MpthreePlayer , but it tries to be more general and cleaner.
The fact that EMMS is based on external players makes it powerful, because it supports all formats that those players support, with no effort from your side.
Main features:
- Free Software (as in Free Speech, and Free Beer)
- Extensible
- Very light (some might even say stealth)
- Audio support : MP3, Ogg Vorbis, FLAC
- Video support : MPEG, WMV, MOV, AVI, OGM, MKV, etc...
- Tagging capability, possibly batched
- Playlist management
- Remotely drivable via emacsclient (playlist creation via rox-filer, for example))
- And last but no least : Written in Emacs lisp.
Enhancements:
- This release includes a large amount of new features, and is released under the GNU General Public License version 3.

GNU tar program provides the ability to create tar archives, as well as various other kinds of manipulation. For example, you can use Tar on previously created archives to extract files, to store additional files, or to update or list files which were already stored.

Initially, tar archives were used to store files conveniently on magnetic tape. The name "Tar" comes from this use; it stands for tape archiver. Despite the utilitys name, Tar can direct its output to available devices, files, or other programs (using pipes), it can even access remote devices or files (as archives).

GNU m4 is an implementation of the traditional Unix macro processor. GNU m4 is mostly SVR4 compatible although it has some extensions (for example, handling more than 9 positional parameters to macros).

GNU m4 also has built-in functions for including files, running shell commands, doing arithmetic, etc.

GNU m4 is a macro processor in the sense that it copies its input to the output expanding macros as it goes. Macros are either builtin or user-defined and can take any number of arguments.

Besides just doing macro expansion m4 has builtin functions for including named files, running UNIX commands, doing integer arithmetic, manipulating text in various ways, recursion etc... m4 can be used either as a front-end to a compiler or as a macro processor in its own right.

Xnee is a suite of programs that can record, replay and distribute user actions under the X11 environment. Think of GNU Xnee as a robot that can imitate the job you just did.
Xnee can be used to:
- Automate tests e.g nightly automatic regression tests
- Demonstrate programs e.g record and replay a user interaction with your system
- Distribute actions e.g teachers actions can be sent to all students desktops
- Record and replay macro e.g Tie a key modifier combination (e.g using xkeymouse) to replay a recorded session. The macro is WM- and program independent.
- Retype a file e.g When testing an editor, Xnee can type in the content of a file. This can be compared with the original and thereby
Xnee consists of a library and two applications:
- cnees not an event amulator Command line program
- gnees not an emulator either Graphical User Interface (GUI) program
- libxnee is basically xnee Library used by cnee and gnee
All Xnee applications (gnee and cnee) receives X11 protocol data (e g XEvents) from an X server using the libxnee and prints them to a file. This file is used later on when replaying.
Events directly generated by the user (e.g KeyPress) can be replayed or faked. Requests, replies, errors and events not directly generated by the user (e.g MapNotify) can be recorded as well. By using these data Xnee applications can replay with synchronisation. This is not only useful but essential.
In order to verify that a program does the job its supposed to do, certain tests have to be made. These tests are, IMHO, perhaps the most boring things a programmer can do. To release the programmer from this burdon Xnee is made.
Xnee started out as a commad line program. During the development phase the main functionality was broken out to a library, called libxnee. The command line program changed its name to cnee. The thought behind making the library was to enable the writing of other clients than just a command line. Today there is a GUI program, gnee that uses the library.
With Xnee testcase(s) can be recorded and later on replayed. Xnee can also distribute events (both when recording and replaying) to other displays.
Xnee uses X Windows System.
Enhancements:
- doc/Makefile.in was missing and has been added. gnee->About->Close and pnee->About->Close were faulty and have been fixed.

Pth is a very portable POSIX/ANSI-C based library for Unix platforms which provides non-preemptive priority-based scheduling for multiple threads of execution also know as multithreading, inside event-driven applications.

All threads run in the same address space of the server application, but each thread has its own individual program-counter, run-time stack, signal mask and errno variable.

The thread scheduling itself is done in a cooperative way, i.e., the threads are managed by a priority- and event-based non-preemptive scheduler. The intention is that this way one can achieve better portability and run-time performance than with preemptive scheduling.

The event facility allows threads to wait until various types of events occur, including pending I/O on filedescriptors, asynchronous signals, elapsed timers, pending I/O on message ports, thread and process termination, and even customized callback functions.

Additionally Pth provides an optional emulation API for POSIX.1c threads ("Pthreads") which can be used for backward compatibility to existing multithreaded applications.
Notice: GNU pth and OSSP pth are exactly the same.

OSSP pth just became an official part of the GNU project some time ago. Thats why its primary name is now GNU pth, although it is still developed by the OSSP project only.

GNU Gadu is an "Instant Messenger" program created to work with protocols popular in Poland (but not only).

GNU Gadu is based on extensible plug-in idea, also graphical user interface (written in GTK+) is a plugin. We support Gadu-Gadu, Tlen.pl and Jabber protocols currently.
